1.0Executive Summary

 

1.1Summary

 

SLR International Corporation (SLR) was retained by Westwater Resources, Inc. (Westwater or the Company) to prepare an independent Initial Assessment (without cash flow analysis) Technical Report Summary (TRS) on the Coosa Graphite Project (the Project or Coosa), located in Coosa County, Alabama, USA. The purpose of this TRS is to disclose an updated Mineral Resource estimate with an effective date of November 30, 2022. This TRS conforms to the United States Securities and Exchange Commission’s (SEC) Modernized Property Disclosure Requirements for Mining Registrants as described in Subpart 229.1300 of Regulation S-K, Disclosure by Registrants Engaged in Mining Operations (S-K 1300) and Item 601 (b)(96) Technical Report Summary.

 

Westwater is a 45-year old public company currently focused on developing battery-grade natural graphite. Originally incorporated in 1977 as Uranium Resources, Inc. to mine uranium in Texas, the Company has been reborn as an energy materials and technology developer. Westwater is focused on battery-grade natural graphite after its acquisition of Alabama Graphite Corp. (AGC) in April 2018.

 

The Coosa graphite deposit is located at the southern end of the Appalachian Mountain range, in Coosa County, Alabama. The deposit area is approximately 50 miles south-southeast of the city of Birmingham and 23 miles south-southwest of the town of Sylacauga. The Project’s mineral tenure is comprised of approximately 41,965 acres of privately owned mineral rights that the Company holds under a long-term lease. The Project is located in the flake graphite belt of central Alabama, also known as the Alabama Graphite Belt.

 

SLR’s Qualified Person (QP) visited the Project on April 21-23, 2022. The SLR QP toured the Kellyton Graphite Plant offices, warehouses, operational areas, and processing facility (currently under construction), located in Kellyton, Alabama. At the Project, the SLR QP also toured drilling and trench site locations in the deposit area, reviewed drill core logging and sampling procedures, reviewed geologic cross sections and previous modeling procedures with Westwater’s geologist and other staff, and discussed ongoing and future exploration plans.

 

A Mineral Resource estimate for the Project, based on 205 drill holes totaling 39,434 ft, was completed by SLR with an effective date of November 30, 2022. Table 1-1 summarizes the Coosa Mineral Resources at a 1.98% graphitic carbon (Cg) cut-off grade envisaging an open pit mining scenario. Indicated Mineral Resources total 26.0 million short tons (Mst) at an average grade of 2.89% Cg for a total of 754,000 st Cg. Inferred Mineral Resources total 97.0 Mst at an average grade of 3.08% Cg for a total of 3.0 Mst Cg.

Notes:

1.The S-K 1300 definitions were followed for Mineral Resources.

2.Mineral Resources are constrained within a Whittle pit shell using a cut-off grade of 1.98% Cg.

3.Mineral Resources are estimated using a long-term graphite concentrate price of US$1,100/st.

4.Bulk density ranges from 1.68 t/m3 to 3.03 t/m3 (0.05 st/ft3 to 0.09 st/ft3).

5.Mining dilution equals 5.0%

6.Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

7.Numbers may not add due to rounding.

8.Mineral Resources are 100% attributable to Westwater.

 

1.1.1Conclusions

 

SLR offers the following interpretations and conclusions on the Project:

 

·Graphite generally occurs as a result of metamorphism (regional or contact) of organic matter in sediments. Flake graphite is assumed to be derived from fine-grained sediments rich in organic matter.

 

·Graphite ores mined historically were almost entirely from the weathered zone (60 ft to 100 ft), partly because weathering is deep in this area and partly because the weathered rock could be gently crushed without blasting.

 

·The sample preparation, analysis, and security procedures at Coosa are adequate for use in the estimation of Mineral Resources.

 

·The quality assurance and quality control (QA/QC) programs as designed and implemented by Westwater and its predecessor AGC meet current industry standard practice and the assay results within the database are suitable for use in a Mineral Resource estimate.

 

·No significant database issues were identified and the SLR QP is of the opinion that the database verification procedures for the Project comply with industry standards and are adequate for the purposes of Mineral Resource estimation.

 

·Relogging of previously drilled holes in conjunction with new drilling information allowed for more accurate interpretation and separation of lithologic units and improved understanding of the geologic environment resulting in:

 

oImproved geologic model correlation to the 2014 Airborne Magnetic survey.

 

oIdentifying widespread and strong vanadium (roscoelite) mineralization in very close association with flake graphite mineralization.

 

·The Company has carried out an extensive geochemical sampling program to determine the presence and intensity of vanadium mineralization at the Project. Vanadium potential tonnage and grade are currently estimated to be 21.0 Mst to 67.0 Mst and 0.19% V2O5 to 0.13% V2O5, respectively. SLR notes that the potential quantity and grade are conceptual in nature, there has been insufficient exploration to define a Mineral Resource, and it is uncertain if further exploration will result in the target being delineated as a Mineral Resource.

1.1.2Recommendations

 

SLR offers the following recommendations regarding the advancement of the Project. Westwater is considering a program to advance the development of the Project, which includes an initial budget estimate of approximately US$1,600,000, as presented in Table 1-2. The program consists of two phases, updating Mineral Resources following completion of the delineation drilling programs. Following completion of the update of the resource estimates, SLR recommends that Westwater proceed with activities that will allow completion of a Pre-Feasibility Study (PFS). The PFS will cover the following activities:

 

·mine planning

 

·metallurgical testwork, pilot plant, product testing

 

·geotechnical and hydrogeological studies

 

·condemnation drilling

 

·tailings management facility design, material characterization and site geotechnical

 

·permitting

 

·environmental management studies and data collection

 

·capital and operating cost estimation

 

·infrastructure evaluation and costing

 

·financial evaluation

 

·project management and administration.

 

1.1.2.1Exploration Drilling

 

1.Complete six-phase infill/delineation drilling activities in the NX, Fixico Mine, SW, Main Grid, Main Grid/Fixico and HS South areas of the Project to convert Inferred oxide resources to the Indicated Mineral Resources category. This work is expected to require approximately 115 drill holes and 1,700 assays. The phased drilling programs are independent of each other and can be conducted simultaneously or on an individual basis. The estimated cost to complete the program is $936,000.

 

2.Drill additional holes down dip and review the classification criteria as more data become available.

 

1.1.2.2Advancement of Coosa Graphite Mineral Resources

 

1.Complete a PFS of the Project and update the S-K 1300 TRS accordingly after completion of the exploration drilling program.

 

2.Revisit and update mining and processing costs and recalculate cut-off grade.

 

3.Revisit and update the Whittle pit with new cost parameters.

A 2% net smelter return (NSR) royalty is payable by Westwater to the lessor from the commercial production and sale of graphite from the properties, as well as royalties for any precious metals, mica, iron, magnetite, manganese, calcium carbonate, copper, tantalum, and rare earths commercially produced and sold from the properties. An additional 0.5% NSR royalty is payable to Charles Merchant, an arm’s length party, who was engaged as an independent contractor to assist AGC with establishing its graphite operations in Alabama.

 

1.2.3History

 

The presence of graphitic schists in Alabama was recognized before the Civil War (1861-1865) by M. Tuomey. Dr. Gessner, employed by the Confederate Government to recover sulfur from the pyrite deposit at Pyriton, is credited with the first discovery of flake graphite in Alabama. The first commercial graphite operation dates back to 1899 when the Allen Graphite Company built a mill near the Quenelda deposits in Clay County using a patented oil flotation process and produced the first refined graphite in Alabama.

 

The mineral and surface rights of four sections in the Fixico Mine area of the Project were acquired by the Fixico Mining Company (Fixico) in 1901-1902. The mine operated from 1902 to 1908. There is no record of the amount of graphite and grade produced.

 

AGC’s subsidiary, Alabama Graphite Co. Inc. (Alabama Graphite), acquired the Project from Eugenia W. Dean (since 2014 the Estate of Eugenia W. Dean), Birmingham, Alabama in 2012 and carried out exploration from 2012 to 2018, including channel sampling, trenching, airborne and ground geophysical surveys, and four drilling programs.

 

Westwater acquired AGC on April 23, 2018. After acquisition, Westwater’s technical staff carried out a review of historical data and geologic information derived from previous graphite exploration drilling and surface trenching programs at Coosa to determine the potential for the presence of substantial vanadium mineralization at the Project. In late 2018, Company personnel carried out an extensive geochemical sampling program, collecting nearly 2,000 samples from many previously completed drill holes and trenches, to determine the presence and intensity of vanadium mineralization at Coosa. The laboratory analytical results of this sampling program outlined widespread and strong vanadium mineralization in very close association with strong flake graphite mineralization at numerous localities within the Project area.

 

1.2.4Geological Setting, Mineralization, and Deposit

 

The Project is located at the southern end of the Appalachian Mountain range, a northeast trending belt of folded and metamorphosed rocks of Neoproterozoic to Lower Paleozoic age. These are covered by the Coastal Plain Sediments of Cretaceous and younger age in the southern half of Alabama. The rocks of the southwestern end of the Appalachians are generally separated into four physiographic and geologic provinces which are, from northwest to southeast: the Interior Low Plateau province, the Appalachian Plateau province, the Valley and Ridge province, and the Piedmont province. The Alabama Graphite Belt is located in the Northern Piedmont.

 

The Northern Piedmont has three structural blocks: the Talladega Block on the northwestern side with low grade greenschist facies metasedimentary and metavolcanic rocks; the central Coosa Block with high grade, upper greenschist to kyanite and sillimanite grade metamorphic rocks, and abundant pegmatite and small granitoid bodies; and the Tallapoosa Block on the southeastern side of high grade, middle to upper amphibolite facies metasedimentary, metavolcanic, and metamorphosed ultramafic and mafic rocks, with large areas of quartz diorite to granitic plutonic rocks.

Technical Report Summary - December 1, 20221-5 

 

 

 

The host of the Project is the Higgins Ferry Formation in the Wedowee Group of the Coosa Block. The Higgins Ferry Formation is defined as an interbedded sequence of four major lithologic units, from top to bottom: a quartz-graphite schist (QGS), a mixed QGS-quartz-muscovite-biotite-graphite schist unit (called INT or intermediate unit), quartz muscovite biotite graphite schist (QMBGS), and a quartz-biotite-garnet schist (QBGS).

 

The Coosa graphite deposits are flake graphite deposits in high grade metamorphic rocks. Graphite flakes occur as part of the rock forming minerals in the schists. They are often associated with disseminated pyrrhotite and minor pyrite. In places, the green vanadium (V) bearing muscovite, roscoelite, also occurs. Minor late stage, straight-sided veinlets of cubic pyrite up to 10 mm wide with smectite clay cross cut the schistosity and pegmatites. The deposits are characterized by deep weathering.

 

The lithologic sequence at Coosa, from top to bottom, is QGS overlying INT, overlying QMBGS, overlying QBGS. QGS generally grades downward into INT, then into QMBGS, which in turn grades downward into QBGS. QMBGS is more highly metamorphosed than QGS and less metamorphosed than QBGS. All of the units are moderately to well foliated, with the foliations probably representing paleo-bedding of the original sedimentary rocks. In addition, several amphibolite intrusives occur on the Project, cutting the metamorphic units and intruding them.

 

QGS is the main host of graphite mineralization at Coosa. QGS can be fine to coarse grained, with minor small biotites and small to medium muscovites, and is usually well foliated. Graphite grades are typically in the order of 2% to 4%, occasionally up to 5% to 7%. QGS also generally contains the largest amount of vanadium-rich muscovite (roscoelite for a field term). Pyrite and/or pyrrhotite can be present, generally averaging less than 1% to 2%, are fine grained, and occur as either disseminated grains or thin (hairline to 1/8 in. thick) veinlets along foliations. Occasional hairline to 1/4 in. thick late pyrite veinlets are found cutting the foliations at high angles. Outcrops of QGS can be light green-gray to dark green, depending on the amount of weathering and oxidation. Roscoelite imparts the light to dark green color to the QGS.

 

INT reflects a gradual increase in metamorphic grade with depth and/or laterally from QGS towards QMBGS. Graphite ranges from 1% to 2%, occasionally up to 3%. In some places there is a gradual increase in the grain size of muscovite and biotite as the QGS is metamorphosed to QMBGS. In other places, the INT unit is marked by interlayers of QGS and QMBGS. These interlayers vary from several inches to several feet thick. Where there is a gradual change from QGS to QMBGS, graphite grade decreases with increasing metamorphic grade. In areas with interlayers of QGS and QMBGS, the QGS layers have higher graphite grade than the QMBGS layers. INT is rarely distinguishable in outcrop, due to limited vertical exposures providing evidence of interlayering and due to the gradual grain size change from QGS to QMBGS. Roscoelite content in the INT decreases with increasing metamorphism from QGS to QMBGS.

 

QMBGS is noticeable by its medium to coarse grained nature and by the large biotites and muscovites that occur along foliations. Biotite can be honey colored to dark brown. Pyrite and pyrrhotite can be present, usually less than 1% to 2% and fine to medium grained. QMBGS is well foliated, with the foliations commonly moderately to strongly contorted. Outcrops can range from light to dark gray to grey-brown. Graphite assays are typically less than 1% to 2%, with the graphite often being coarse grained due to recrystallization of the graphite grains.

 

1.2.5Exploration

 

Several surface exploration campaigns were conducted between 2012 to 2015. Due to the lack of outcrop and dense vegetation, the exploration techniques used were rock sampling in channels mainly along road cuttings, trenching, geophysics, and drilling. Since acquisition of the Project in 2018, Westwater has completed in-fill/delineation diamond drilling for a total of 5,551 ft in 65 holes. The Company has also conducted a geochemical sampling program using available core and trench material to determine the presence and intensity of vanadium mineralization at the Project.

Technical Report Summary - December 1, 20221-6 

 

 

 

To date, a total of 236 holes for 45,715 ft have been drilled at the Project, of which 205 holes totaling 39,434 ft were used in the Mineral Resource estimation. Since 2012, most drilling was focused on the Main Grid and NX target areas of the Project.

 

1.2.6Mineral Resource Estimate

 

A Mineral Resource estimate was completed by SLR using a conventional block modeling approach. The general workflow performed by SLR included the construction of a geological or stratigraphic model representing the Higgins Ferry Group Graphitic Schist sequence in Seequent’s Leapfrog Geo (Leapfrog Geo) from mapping, drill hole logging, and sampling data, which was used to define discrete domains and surfaces representing the upper contact of each unit. The geologic model was then used to constrain resource estimation. The resource estimate used regularized block models, the inverse distance squared (ID2) methodology, and length-weighted, 10 ft, uncapped composites to estimate the Cg and V in a three-search pass approach, using hard boundaries between subunits, ellipsoidal search ranges, and search ellipse orientation informed by geology. Average density values were assigned by lithological unit.

 

Estimates were validated using standard industry techniques including statistical comparisons with composite samples and parallel nearest neighbor (NN) estimates, swath plots, and visual reviews in cross-section and plan. A visual review comparing blocks to drill holes was completed after the block modeling work was performed to ensure general lithologic and analytical conformance and was peer reviewed prior to finalization.

 

Mineral Resources have been classified in accordance with the definitions for Mineral Resources in S-K 1300. Mineral Resources estimated by SLR used all drill results available as of March 17, 2022, and are summarized in Table 1-1.

 

To ensure that all Mineral Resource statements satisfy the “reasonable prospects for eventual economic extraction” (RPEEE) requirement, factors significant to technical feasibility and potential economic viability were considered. Mineral Resources were defined and constrained within an open-pit shell prepared by SLR and based on a US$1,100/st graphite value.

 

The SLR QP is of the opinion that with consideration of the recommendations summarized in this section of the TRS, any issues relating to all relevant technical and economic factors likely to influence the prospect of economic extraction can be resolved with further work. There are no other known legal, social, or other factors that would affect the development of the Mineral Resources.

2.0Introduction

 

SLR International Corp. (SLR) was retained by Westwater Resources, Inc. (Westwater or the Company) to prepare an independent Technical Report Summary (TRS) on the Coosa Graphite Project (the Project or Coosa), located in Coosa County, Alabama, USA. The purpose of this TRS is to disclose an updated Mineral Resource estimate with an effective date of November 30, 2022.

 

This TRS conforms to United States Securities and Exchange Commission’s (SEC) Modernized Property Disclosure Requirements for Mining Registrants as described in Subpart 229.1300 of Regulation S-K, Disclosure by Registrants Engaged in Mining Operations (S-K 1300) and Item 601 (b)(96) Technical Report Summary.

 

Westwater is a 45-year old public company currently focused on developing battery-grade natural graphite. Originally incorporated in 1977 as Uranium Resources, Inc. to mine uranium in Texas, the Company has been reborn as an energy materials and technology developer. Westwater is focused on battery-grade natural graphite after its acquisition of Alabama Graphite Corp. (AGC) in April 2018.

 

The Coosa graphite deposit is located at the southern end of the Appalachian Mountain range, in Coosa County, Alabama. The deposit area is approximately 52 miles south-southeast of the city of Birmingham and 23 miles south-southwest of the town of Sylacauga. The Project’s mineral tenure is comprised of approximately 41,965 acres of privately owned mineral rights that the Company holds under a long-term lease. The Project is located in the flake graphite belt of central Alabama, also known as the Alabama Graphite Belt.

 

AGC acquired the Project in 2012 based on the geologic setting. On April 23, 2018, Westwater acquired a 100% interest in AGC as part of a strategic decision to refocus the Company to supply battery manufacturers with low-cost, high-quality, and high-margin natural graphite products. As a result of that business transaction, Westwater became the owner of the Project.

 

The Coosa graphite deposit is expected to be mined by conventional small-scale open pit mining methods through several shallow pits (less than 100 ft deep each) that will be developed over life of the project. At full-scale production, the mining rate will be approximately 577,000 short tons per annum (stpa), at an average grade of 3.2% Cg. Mine operations will employ small conventional loading and haulage equipment, including a 6.0 cubic yard excavator and 45-ton articulated haul trucks. Mineralized material will be ripped with a bulldozer to prepare the mineralized material for mining with the excavator.

 

In late November 2018, Westwater announced the discovery of significant concentration of vanadium-bearing micas at several locations, hosted in the graphitic schists at Coosa. Westwater subsequently commenced the first of a four-phase exploration program designed to determine the extent, character, and quality of the vanadium mineralization at Coosa. As announced by the Company on February 19, 2019, the first phase demonstrated widespread positive values for vanadium that extended beyond the Coosa graphite deposit.

 

2.1Site Visits

 

SLR’s Qualified Person (QP) visited the Project on April 21-23, 2022. The SLR QP toured the Kellyton Graphite Plant offices, warehouses, operational areas, and processing facility (currently under construction), located in Kellyton, Alabama. At the Project, the SLR QP also toured drilling and trench site locations in the deposit area, reviewed drill core logging and sampling procedures, reviewed geologic cross sections and previous modeling procedures with Westwater’s geologist and other staff, and discussed ongoing and future exploration plans.

3.0Property Description

 

3.1Location

 

The Coosa graphite deposit is located at the southern end of the Appalachian Mountain range, in the western part Coosa County, Alabama, USA. The deposit area is approximately 50 miles (mi) south-southeast of the city of Birmingham and 23 mi south-southwest of the town of Sylacauga. The Project is located in the flake graphite belt of central Alabama, also known as the Alabama Graphite Belt.

 

3.2Land Tenure

 

The Coosa property mineral tenure is comprised of approximately 41,965 acres of privately owned mineral rights held by Westwater under a long-term lease located in parts of townships T. 21 N., T. 22 N., T. 23 N., and T. 24 N. and ranges R. 16 E., R. 17 E., R. 18 E., and R. 19 E. The western boundary is approximately the Coosa River.

 

The primary target areas of interest for this TRS are located in parts of Sections 4, 5, 6, 7, 8, and 9, T. 22 N, R. 17 E, Coosa County, Alabama. The primary area of interest is referred to as the Coosa Graphite Project and is divided into six target areas (HS-North is excluded from this resource estimate due to limited number of drill holes):

 

1.Northern Extension (NX)

 

2.Main Grid

 

3.Southwest Extension (SW)

 

4.Fixico Mine

 

5.HS-North

 

6.HS-South

 

The approximate geographical center of the target areas of interest is located at 32°54’40.7”N and longitude 86°23’52.4”W. All surface data coordinates are State Plane 1927 Alabama East FIPS 0101 (US feet) system. Maps of the Project location, mineral rights, and target areas are provided in Figure 3-1, Figure 3-2, and Figure 3-3 respectively. A list of the mineral rights is given in Table 3-1.

 

The mineral rights are patents of private land issued between 1842 and 1860. The surface land rights were subsequently sold separately from the mineral rights and are now held by a different owner. The ownership of the mineral rights is a matter of public record in the Probate Records of Coosa County, Alabama. The authority for the State of Alabama non-fuel minerals surface mining is the Alabama Department of Labor, Mining Division. No assessment work is required to hold mineral rights on private land. The mineral rights were granted in perpetuity. The Coosa mineral rights are identified by their township, range, section and, where relevant, quarters, in the same manner as land rights, and do not have an identification number or name. The mineral rights have not been surveyed.

 

As the mineral rights are patents of private land and were issued before the introduction of the General Mining Law of 1872, which governs mining on Federal public lands, this law is not applicable to the Project and the mineral rights are not held as either patented or unpatented lode claims. Thus, the mineral rights do not have claim names and are not defined by metes and bounds.

3.3Underlying Agreement

 

On August 1, 2012, AGC’s subsidiary, Alabama Graphite Co. Inc. (Alabama Graphite), a company registered in Alabama, entered into a Mining Lease Agreement (the Agreement) and Option with Eugenia W. Dean (since 2014 the estate of Eugenia W. Dean), Birmingham, Alabama pursuant to which it: (a) leased the mineral rights in respect to an area with the potential for graphite comprising 14,020.86 acres (approximately 5,674 ha) in township 22N, range 17E, Coosa County, Alabama; and (b) received an option of first refusal to lease the mineral rights to adjacent areas comprising 30,756.52 acres (12,447 ha). On November 5, 2012, Alabama Graphite exercised the option and leased an additional 27,944.02 acres (approximately 11,308 ha) of the remaining available acres under the same terms as in the initial agreement. The total property under lease is now 41,964.88 acres (approximately 16,982 ha).

 

Under the terms of the Agreement, the lease is for successive renewable five-year terms (not to exceed 70 years) in consideration of an initial cash payment of $30,000 and annual advance royalty payments of $10,000, starting on July 1, 2015 (paid). Alabama Graphite also paid $1,000 for the Option and was required to make annual payments of $1,000 to keep the Option in good standing. Alabama Graphite made a payment of $48,537 on November 5, 2012, to exercise the Option as an initial three-year payment through November 4, 2015, and issued 25,000 shares to the lessor.

 

Alabama Graphite is also obliged to pay the lessor a net smelter returns (NSR) royalty of 2% from the commercial production and sale of graphite from the properties, as well as royalties for any precious metals, mica, iron, magnetite, manganese, calcium carbonate, copper, tantalum, and rare earths commercially produced and sold from the properties.

 

In connection with entering into the Agreement and Option, Alabama Graphite engaged Charles Merchant (Merchant), an arm’s length party, as an independent contractor to assist it with establishing its graphite operations in Alabama. As consideration for his services, Alabama Graphite paid Merchant the cash sum of $320,000 and he is entitled to 800 common shares1 of the Company (the “Finder’s Shares”) to him once Alabama Graphite has a surface rights agreement to engage in meaningful mining operations on the mineral interests for the Coosa Graphite property. There is currently no surface rights agreement in place for the Coosa Graphite property.

 

 

 

1On August 1, 2012, an Agreement was executed by Mr. Merchant, Alabama Graphite Company, Inc., and Keymark Resources, Inc. (Keymark), which provided Mr. Merchant with an ownership interest in 500,000 shares of Keymark common stock but with that ownership only vesting on the Surface Rights Date. The Surface Rights Date is the date when a Surface Rights Agreement is executed; a Surface Rights Agreement would allow AGC to engage in meaningful mining operations on the mineral interests specified in the Agreement; and there is no Surface Rights Agreement currently in place for any properties associated with the Coosa Graphite properties. At the time of the execution of the Agreement, Keymark was the parent company for Alabama Graphite Company, Inc. On August 31, 2012, Keymark changed its name to Alabama Graphite Corp. (AGC), When Westwater acquired AGC on April 23, 2018, each share of AGC common stock was exchanged for 0.08 shares of Westwater’s common stock. In other words, the 500,000 shares of AGC’s stock became 40,000 shares of Westwater’s common stock. Further, one year later on April 23, 2019, following approval by Westwater’s stockholders and an action by the Westwater Board of Directors, a 1-for-50 reverse split of Westwater’s common stock became effective, and those 40,000 shares would now be only 800 shares.

Alabama Graphite is obliged to pay Merchant an additional $100,000 upon receipt by Alabama Graphite of a bankable feasibility study (FS) in respect of the leased property and a further $150,000 upon full permitting of the leased property. This TRS is not an FS, and currently the Coosa Graphite property does not have any permits. The Company is also obliged to pay Merchant NSR royalties of 0.5% up to an aggregate amount of $150,000 if and when graphite mining operations commence on the leased property.

 

3.4Encumbrances

 

On November 23, 2020, Westwater executed a temporary access permit (TAP) with Hancock Forest Management, Inc. (Hancock) which currently owns the surface rights for the Coosa graphite properties. Hancock purchased the surface rights from Headwaters Investment Corp. in 2018. The TAP allows Westwater to engage in core drilling and testing for graphite deposits, and to travel to the Project via vehicles on existing roads and routes, until January 31, 2023. On January 28, 2021, the TAP was amended to allow access to the property even during the hunting season provided hunter orange vests are worn.

 

Previously, AGC had a Surface Use Agreement with Headwaters Investments Corporation covering 3,481 acres (1,409 ha). The first period of that agreement was until September 1, 2013, and it was renewed for a second period until September 30, 2015. The agreement covered the area of the drill grid and allowed AGC to carry out exploration including sampling, trenching and drilling. Payments of $53,000 were made for the first period and $50,000 for the second period plus a guarantee of $20,000 placed in escrow. The payments were based on the amount of anticipated surface disturbance. The Surface Use Agreement provided for unrestricted access to the property with the stipulation that AGC is responsible for reclamation of any surface disturbance caused by its exploration activities.

 

Headwater Investments Corp. has fee simple ownership of the surface rights. They are required to pay an annual property tax of $1.13 per acre. The property taxes have been paid in full to date and the property is in good standing.

 

3.5Royalties

 

SLR is not aware of any royalties other than those discussed in the previous sections.

 

3.6Required Permits and Status

 

Exploration, road access, and drilling at the Project is subject to environmental permits from the Alabama Department of Environmental Management (ADEM) including a Construction storm water permit under the National Pollutant Discharge Elimination System (NPDES), and General Permit #ALR1000000 authorizing discharges. A Construction Best Management Practices Plan (CBMPP) was issued on March 12, 2021 for Westwater’s 2021-2022 drilling program and expires on March 31, 2026.

 

3.7Other Significant Factors and Risks

 

SLR is not aware of any environmental liabilities on the property. Provided that TAP is extended beyond its current expiration date of January 31, 2023, Westwater has all required permits to conduct the proposed work on the property. SLR is not aware of any other significant factors and risks that may affect access, title, or the right or ability to perform the proposed work program on the property.

4.0Accessibility, Climate, Local Resources, Infrastructure and Physiography

 

4.1Accessibility

 

Access to the Project site is via Highway US 280 for approximately 50 mi south from Birmingham, Alabama to State Highway AL-9S, then approximately 10 miles west to State Highway AL-22 W, 12 mi west to Coosa County Road 29, and 12 mi north to the property. Sylacauga and Alexander City, Alabama, located approximately 24 mi and 38 mi respectively from the property are the closest small cities with hotels and services. The nearest major airport with scheduled flights is in Birmingham, Alabama, and there is an airfield at Sylacauga. All material mined from the Project will be milled at the Project site and the concentrate will be transported to Westwater’s graphite processing plant located in Kellyton, Alabama, approximately 35 mi to the east.

 

4.2Climate

 

The climate zone of Alabama is classified as humid subtropical (Cfa) under the Koppen Climate Classification. The Holdridge Life Zones Climate Classification is subtropical moist forest.

 

The nearest climatic data available is for Sylacauga, 20 mi northeast of the Project. The average annual temperature is 61.7°F. The warmest month is July with an average temperature of 78.7°F and the coolest month is January with an average temperature of 43.2°F. The maximum average high is 90.6°F in July, and the minimum average low is 31.4°F in January. Average annual precipitation is 55.2 in. The wettest month is March with an average of 5.9 in. Snow is rare with an average of 0.8 in. It is humid in the summer. The state is prone to tropical storms, hurricanes, thunderstorms, and tornadoes. Due to the moderate climate in the Project area, the operating season is year round.

 

4.3Local Resources

 

Personnel and supplies for future mining operations are expected to be sourced from the nearby towns of Birmingham and Sylacauga, Alabama (50 mi and 23 mi, respectively). The area within 10 mi of the property is very sparsely populated, so a mine would directly affect very few people. Mining has been a traditional industry in the area, and marble quarries are still active.

 

4.4Infrastructure

 

There is no infrastructure in the immediate area of the property, other than a network of well-maintained logging access roads. An electrical transmission line occurs approximately one mile west of the drill grid. Water is abundant in small streams and in Mitchell Lake, a large impoundment on the Coosa River at the western edge of the property.

 

4.5Physiography

 

The property is located in an area of ridges and valleys with elevations of approximately 350 fasl to 1,200 fasl. The area of the drill grid is a peneplain surface dipping gently south at an elevation of 600 fasl to 700 fasl and incised by a meandering river system to give a local relief of up to 300 ft. The elevations of the drill collars vary from approximately 351 fasl to 766 fasl.

The land use is forestry with thick mixed hardwoods and pines, and significant areas of pine plantations which are harvested every 20 to 25 years. There are clearings at towns and for agriculture. Due to extensive weathering, natural outcrops are sparse and most useful exposures are in road cuts, stream drainages, or old mine workings.

 

Weogufka Creek runs from northeast to southwest on the north side of the drill grid, and joins Swamo Creek, the Coosa River, and the Mitchell Lake dam. This is a tributary of the Alabama River which flows southwest, becomes the Mobile River, and then flows into the Gulf of Mexico at Mobile.

5.0History

 

5.1Prior Ownership

 

The long and complicated history of ownership of the mineral and surface rights of the Project is described in the Preliminary Title Review dated May, 2021 and prepared by Deborah L. S. Goetz of Landres Management Consultants, for Sections 3, 4, 5, 7, 8 and 9, Township 22 N, range 17 E, where AGC and Westwater have carried out exploration activities. A brief summary is provided below.

 

The mineral and surface rights of Sections 3, 4, 5, 7, 8 and 9 are patents of private land issued between 1842 and 1860. Most of them were acquired by the Fixico Mining Company in 1901-02. Several other companies and individuals owned other parts. Following bankruptcy of Fixico in 1910, their mineral and surface rights were acquired by John R. Hegeman. In 1929, the mineral rights were acquired by Charles A. Dean (senior). He acquired more mineral rights over the years and, on his death in 1952, they passed to multiple heirs who sold a half interest to Robert A. Russell. In 1980, Charles A. Dean, Junior, acquired all of the mineral rights from the other Dean heirs and the Russell heirs. On the death of Charles A. Dean, Junior in 2008, the mineral rights were inherited by his wife, Eugenia W. Dean, and following her death in 2014, they were inherited by the Estate of Eugenia W. Dean.

 

On August 1, 2012, AGC’s subsidiary, Alabama Graphite, a company registered in Alabama, entered into a Mining Lease Agreement and Option with Eugenia W. Dean (since 2014 the estate of Eugenia W. Dean), Birmingham, Alabama pursuant to which it: (a) leased the mineral rights in respect to an area with the potential for graphite comprising 14,020.86 acres (approximately 5,674 ha) in township 22N, range 17E, Coosa County, Alabama; and (b) received an option of first refusal to lease the mineral rights to adjacent areas comprising 30,756.52 acres (12,447 ha). On November 5, 2012, Alabama Graphite exercised the option and leased an additional 27,944.02 acres (approximately 11,308 ha) of the remaining available acres under the same terms as in the initial agreement. The total property under lease is now 41,964.88 acres (approximately 16,982 ha).

 

On April 23, 2018, Westwater acquired a 100% interest in Alabama Graphite as part of a strategic decision to refocus the Company to supply battery manufacturers with low-cost, high-quality, and high-margin natural graphite products. As a result of that business transaction, Westwater became the owner of the Coosa Graphite Project, which was the principal asset of Alabama Graphite.

 

5.2Exploration and Development History

 

5.2.1The Alabama Graphite Belt

 

The following sections describe the history of graphite mining and exploration in the Alabama Graphite Belt and is provided for background information on the regional setting of the Coosa Project. The information is taken from published sources as summarized by Pallister and Thoenen (1948) and Durgin (2013). These are not necessarily an indication of the mineralization that occurs on the Coosa Project.

 

The Alabama Graphite Belt is a 70 mi long, northeast-trending belt in Clay, Coosa, and Chilton Counties. Most of the historical mines were in the northeast segment around Ashland, Clay County (Area A of Pallister and Thoenen, 1948), approximately 18 mi long, separated by an 11 mi gap from the 40 mi long, southwest segment extending from Goodwater, Coosa County, to Verbena, Chilton County (Areas B and C). The geology of the graphite deposits at Ashland was described by Brown (1925). The Coosa Project occurs beside the historic Fixico Mine in the southwestern part of the belt (Area C).

The presence of graphitic schists in Alabama was recognized by M. Tuomey before the Civil War (1861-1865; Jones, 1929). Dr. Gessner, employed by the Confederate Government to recover sulfur from the pyrite deposit at Pyriton, is credited with the first discovery of flake graphite in Alabama (Clemmer et al., 1941). The first attempt at development was in 1888, however, an experimental mill using water for flotation was unsuccessful. The first commercial graphite operation dates back to 1899 when the Allen Graphite Company built a mill near the Quenelda deposits in Clay County using a patented oil flotation process and produced the first refined graphite in Alabama.

 

The Fixico Mine in Coosa County, adjacent to the Project, and the Dixie Mine in Chilton County began operations in the early 1900s. By 1906, there were several mines in operation and by 1913, the graphite industry was well established in central Alabama. World War I caused the disruption of foreign graphite imports, leading to significantly higher prices and the Alabama graphite industry boomed. By 1918, there were 25 flotation plants operating in the district with a total production in 1918 of 7.8 million pounds of graphite (Pallister and Thoenen, 1948).

 

The end of the war and the resumption of foreign imports depressed prices and the Alabama graphite industry dwindled to seven operating plants in 1920. In 1929, the last two mines in the district, the Ceylon Graphite Company in Coosa County and the Superior Flake Plant in Clay County, were closed.

 

At the start of World War II in 1939, C. J. Johnson rebuilt the mill at the Ceylon Mine and began production of flake graphite on a small scale. In 1940, as a result of the interruption of graphite imports from Madagascar, the US Bureau of Mines made a preliminary survey of the Alabama graphite deposits to determine the viability of resumption of mining, with a report by Clemmer et al. (1941). As the demand for graphite rose, the War Production Board, the Metals Reserve Company, and the Reconstruction Finance Corporation (all federally funded) turned their attention to the district, and a detailed study of the district was carried out between 1942 and 1944 which resulted in a report by Pallister and Thoenen (1948). Based on this report, the graphitic deposits were found to contain significant amounts of green vanadium-bearing mica (roscoelite). A total of 11 mining areas including 49 graphite deposits were mapped and studied in detail for graphite and vanadium. More than nine miles of access roads were built; 17,930 ft of bulldozer trenches, 2,670 ft of power scoop trenches, 5,234 ft of hand trenches, and 3,279 ft of existing trenches were dug and sampled. Diamond drilling totaled 5,453 ft in 84 holes (Pallister and Thoenen, 1948).

 

A field laboratory was established in Ashland with the capacity for pilot crushing-milling-flotation testing and graphite analyses. In 1943, the Crucible Flake Mill of Haile Mines, Inc. and the Alabama Flake Graphite Co. plant (Gisler, 1943) began to produce. The three plants produced 8.1 Mlb of graphite, with Alabama again ranking first in graphite production in the US. The Crucible Flake Mill was closed at the end of 1943, leaving only two producers in the district.

 

After World War II, production declined rapidly due to the resumption of imports and subsequent decline in prices. By 1950, only the Pocahontas Mine near Ashland and the Bama Mine in Chilton County were still in production, and they closed in 1953. The Alabama graphite industry has been idle since that time. The processing plants have all been dismantled, burned down, or overgrown, and the graphite workings are hidden under more than 60 years’ vegetation. With the current resurgence of interest in graphite deposits, attention is being turned again to the central Alabama Graphite District.

 

Mineable grade graphite bodies were greatly elongated along strike and were referred to as “leads”, and often included selvages of waste rock. Cameron and Weiss (1960, p. 263) described the leads as follows:

 

The total length of some of the larger leads may be measurable in miles, but the full length of a lead is not necessarily ore, for there is much variation in graphite content both along and across strike. A typical section shows alternating layers of rocks of low graphite content, of high graphite content, and of intermediate graphite content. The individual layers range from fractions of an inch (<1 cm) to 10 feet (3 m) in thickness, with aggregate thickness in some cases greater than 100 feet (30 m). Exposures outside the mine workings are poor and none of the individual leads is exposed. The Pocahontas lead was traced by trenching along strike for approximately 4,000 feet (1,220 m) and Brown (1925) reported that he was able to trace a lead on the Griesemer property for a like distance.

Two good examples of mines in the Ashland area are the Quenelda Mine and the Pocahontas Mine. At Quenelda, there were seven pits spaced along the strike of the leads for approximately 2,000 ft. The pits were almost entirely in weathered mineralization along two leads 20 ft to 40 ft apart. The southeast lead was 40 ft to 65 ft thick, and the northwest lead was 50 ft to 80 ft thick, with a strike of 55° to 75° to the northeast and a dip of 55° to 85° to the southeast. Graphite grades averaged approximately 3.0%.

 

The Pocahontas Mine of the Alabama Flake Graphite Company was one of the last operating mines in Alabama. The workings comprised three parallel open cuts in the leads that were approximately 50 ft wide and several hundred feet long. The depth of weathering could exceed 80 ft. Pallister and Thoenen (1948) indicated that the lead was shown to extend for another 2,400 ft southwest from the third cut. The grade was reported to average 4.0% to 5.0% graphite in later years.

 

The two most significant mines in the southwestern portion of the Alabama Graphite Belt were the Ceylon and Bama mines. The Ceylon deposit is located approximately eight miles west of the town of Goodwater. One of the largest mines in the district, it operated from 1916 to 1929 and from 1939 to 1947. The principal working developed during the later period was 925 ft long, up to 300 ft wide, and up to 70 ft deep on a series of leads striking 45° to the northeast and dipping 55° to the southeast. The grade ranged from 2.0% to 6.0% graphite and averaged 3%.

 

The Bama Mine in Chilton County near the southwest end of the graphite belt operated from 1925 to 1930 when the mill burned down. The main pit was 625 ft long, 150 ft wide, and 40 ft to 80 ft deep. Two smaller pits approximately 200 ft long were mined along strike between the main pit and the mill. The deposits trended 20° to 25° to the northwest and dipped 50° to 60° to the south, due to the presence of a large fold.

 

5.2.2Coosa

 

The Fixico Mine is located approximately 0.5 mi southeast of the Coosa Main Grid area and is a former producer that operated from 1902 to 1908. There is no record of the amount of graphite and grade produced. Westwater geologists have located the old pits and the old wooden dam, described below. The mine was described by Pallister and Thoenen (1948, pp. 72-73):

 

The Fixico graphite mine, named for the Indian chief Fixico, who lived near the mine. It is in the southern part of sec. 8, T. 22 N., R. 17 E., 11 miles west of Rockford. C. F. Whoolock, who first used a “flotation” process to separate graphite in 1898 at the A. A. Allen plant in Clay County, operated the Fixico mine with his son Kennard. About 1902, they built a log dam, which is still intact, a mill, and houses for their employees and operated the mine until about 1908. It is thus probably the oldest mine in Coosa County.

The graphitic schist that was mined is exposed on the western slope of a tributary of Hatchett Creek, the backwater of which, caused by the Mitchell Dam, is not far from the property. The western slope rises for over 100 feet above the creek level, and the pits open off a small cross valley. Mine pits were opened at various levels and running at angles from northeast through west to southwest. The largest pit is about 10 feet above the creek and extends northeast for a distance of 150 feet. It is 75 feet wide and 50 feet deep at the face. A short distance to the northwest are two parallel pits each 100 feet long, 25 to 30 feet wide, and 30 feet deep with a narrow “horse” between them. The floor of these pits is 40 feet higher than the floor of the largest pit. Four additional pits cut across the top of the slope towards the west, and two more extend southwest at a lower level opposite the northeast pits.

 

The schist has a general N45°E strike and 45°SE dip. The beds of graphitic schist extend for 150 to 200 feet in thickness, with barren layers between the schist beds. The country to the northeast rises for 400 to 500 feet before it drops off, giving room for large possible reserves.

 

From 2012 to 2018, exploration on the Project was carried out by AGC’s subsidiary Alabama Graphite and included channel sampling, trenching, airborne and ground geophysical surveys, and drilling. Further details for Alabama Graphite’s exploration are provided in Section 7 of this TRS.

 

5.3Historical Resource Estimates

 

A thorough review was made of all the known graphite producing areas in the Alabama Graphite Belt district in 1942-1944 (Pallister and Thoenen, 1948), which resulted in a historical mineral resource estimate of 25,910,000 st in all classes. This included 11,059,000 st of “measured weathered ore reserves”, 3,351,000 st of “Inferred weathered ore”, and 11,500,000 st of “unweathered ore” in “Measured”, “Indicated” and “Inferred” categories, with an average recoverable grade in the “Measured weathered ore” estimated at 3.0% graphite (Pallister and Thoenen, 1948, p. 77).

 

These estimates are considered historical in nature as they predate the introduction of the SEC standards and S-K 1300 and are quoted for information purposes only and should not be relied upon. These are mineral resource estimates rather than mineral reserve estimates. The assumptions, parameters, and methods used to make these estimates are not stated in the original publication. The historical resources include multiple deposits throughout the Alabama Graphite District. They were made to evaluate the potential of the whole district. A QP has not completed sufficient work to classify the historical estimate as current Mineral Resources or Mineral Reserves, and Westwater is not treating the historical resource estimate as current Mineral Resources or Mineral Reserves.

 

5.4Past Production

 

There is no record of the amount of graphite and grade produced from the Fixico Mine area and no production has taken place on other parts of the Project.

 

There has been historical production from the Alabama Graphite Belt, however, the records are not complete. In 1899, the Allen Graphite Company “was able to produce several hundred tons of graphite” (Jones, 1929). In 1917-1919 Alabama ranked first in production of flake graphite in the USA, and again in 1943 (Pallister and Thoenen, 1948). Between 1913 and 1920, approximately 35.5 Mlb of graphite were produced, with the greatest number of producers in 1918.

 

In 1929, three mills produced 3.5 Mlb of graphite, but all were closed by 1930. In 1943, a total of 8.1 Mlb were produced, and two mills continued to produce until 1953. Production statistics are unavailable.

6.0Geological Setting, Mineralization, and Deposit

 

6.1Regional Geology

 

The Project is located at the southern end of the Appalachian Mountain range, a northeast trending belt of folded and metamorphosed rocks of Neoproterozoic to Lower Paleozoic age. These are covered by the onlap Coastal Plain Sediments of Cretaceous and younger age in the southern half of Alabama. The geology of Alabama is shown in Figure 6-1. The rocks of the southwestern end of the Appalachians are generally separated into four physiographic and geologic provinces which are, from northwest to southeast: the Interior Low Plateau province, the Appalachian Plateau province, the Valley and Ridge province, and the Piedmont province. The Alabama Graphite Belt is located in the Northern Piedmont.

 

The regional geology is described by Raymond et al. (1988) in “Alabama Stratigraphy”. The Interior Low Plateau is a Paleozoic limestone plateau of moderate relief. The Appalachian Plateau is underlain by a thick series of carbonates overlain by sandstones and shales of Cambrian to Pennsylvanian age. The rocks have open folding and are moderately dissected resulting in sandstone and shale synclinal plateaus and, in the eastern part, three linear anticlinal limestone valleys. The Valley and Ridge Province is a fold-thrust belt, with east dipping thrusts, of carbonates, sandstones, and shales of Cambrian to Pennsylvanian age, similar to the stratigraphy of the Appalachian and Interior Low Plateaus. It is separated from the Appalachian Plateau by a large scale east dipping thrust fault and consists of a series of subparallel ridges and valleys.

 

The Piedmont Province is formed of Neoproterozoic to early Paleozoic metamorphic rocks. The metamorphic grade increases across the Piedmont from lower greenschist facies in the northwest to high grade migmatite facies in the southeast. It is divided into three lithotectonic provinces which are, from northwest to southeast: the Northern Piedmont, Inner Piedmont, and Southern Piedmont, each bounded by major faults. The physiography of the Northern Piedmont is characterized by prominent ridges with peaks up to 2,407 ft, becoming lower to the southeast. The Inner and Southern Piedmont provinces have much more subdued topography.

 

The Northern Piedmont has three structural blocks:

 

The Talladega Block on the northwestern side with low grade greenschist facies metasedimentary and metavolcanic rocks (marble, phyllite, sandstone, chert, quartzite, greenstones);

 

The central Coosa Block with high grade, upper greenschist to kyanite and sillimanite grade metamorphic rocks (phyllite, schist, graphite schist, gneiss, migmatitic gneiss, quartzite, amphibolites), including the Alabama Graphite Belt, and abundant pegmatite and small granitoid bodies;

 

The Tallapoosa Block on the southeastern side of high grade, middle to upper amphibolite facies metasedimentary rocks (phyllite, gneiss), metavolcanic (amphibolite) and metamorphosed ultramafic and mafic rocks (pyroxenite, gabbro), with large areas of quartz diorite to granitic plutonic rocks.

 

The Coosa Block is thrust over the younger, lower-greenschist facies metamorphic rocks of the Talladega Block along the Hollins Line Fault, located three miles northeast of the Coosa graphite deposit.

 

The Inner Piedmont includes two groups of high grade metamorphic rocks, including schists, gneisses, and amphibolites: the Dadeville (schist, amphibolite, gneiss, granitic gneiss) and Opelika (schist, gneiss) complexes, with pyroxenite lenses and deformed granites.

Technical Report Summary - December 1, 20226-1 

 

 

 

The Southern Piedmont occupies the southeastern corner of the region. It is also underlain by high grade metamorphic rocks of the Pine Mountain Block and the Wacoochee and Uchee complexes. The Pine Mountain Block contains quartzite, quartzitic schists, and dolomitic marble. The Wacoochee Complex is largely granitic gneiss and feldspathic muscovite-biotite schist. The Uchee Complex contains a dioritic gneiss and a leucocratic quartz diorite. Folding is much less evident there.

 

Regionally, the Coosa Block is interpreted to be part of the Eastern Blue Ridge terrane which formed on the rifted margin of Laurentia on the breakup of the Rodinia super-continent in the Neoproterozoic, and consists of rifted margin metasedimentary and rift-related volcanic rocks (Hatcher, 2010). The southern part underwent metamorphism to upper amphibolite facies in the Taconian orogeny at 460 to 455 Ma (Upper Ordovician) and is bounded on the west side by the Taconian suture (Hollins Line Fault) which can be traced for the length of the Appalachians, with different names. The Western Blue Ridge terrane including the Talladega belt is a Laurentian margin terrane of Neoproterozoic to Lower Carboniferous (Mississippian) age which was deformed and accreted in the Devonian to Mississippian Neoacadian orogeny (Hatcher, 2010).

6.2Local Geology

 

Information on local geology is based on an internal memorandum by David Greenan, Consulting Geologist, Westwater (Greenan, 2022) and other documentation provided to SLR by Westwater.

 

The Coosa graphite deposit is hosted in high grade metamorphic rocks. Graphitic carbon (Cg) material is present in two types of schist of an uncertain age ranging from Precambrian to Paleozoic, a quartz-graphite schist, which generally has grades greater than 1% Cg, and a quartz-biotite-graphite schist, which has grades generally less than 1% Cg.

 

The host schists exhibit both regional and local folding as well as local-scale low and high angle faulting. Foliations within the mineralized intervals display a variety of dips, ranging from low angle to steeply dipping features. A strong and well developed weathering profile is present in the mineralized units throughout the Project area, with a strongly weathered zone (“saprolite”) exposed at the surface and locally extending to a depth of up to 100 ft. The strongly weathered units overlie a “transition zone” of mixed oxidized and unoxidized material, which in turn, overlies an unoxidized (unweathered or reduced) zone. While the strongly weathered graphitic schist is the primary target of Westwater’s exploration and development evaluation, strong flake graphite mineralization is present in the transition and unweathered zones as well. Graphite mineralization is widespread throughout Westwater’s surface and mineral property holdings, however, the focus of previous exploration has been centered upon the so-called Main Grid area deposit, and its northeastern and southwestern extensions and only portions of the HS-North, HS-South, and Fixico Mine target areas have been tested.

 

6.3Property Geology

 

Information on property geology is based on an internal memorandum by David Greenan, Consulting Geologist, Westwater (Greenan, 2022) and other documentation provided to SLR by Westwater.

 

The host of the Project is the Higgins Ferry Formation in the Wedowee Group of the Coosa Block (Figure 6-2). The Higgins Ferry Formation is defined as an interbedded sequence of three major lithologic units, from top to bottom:

 

1.Quartz-graphite schist (QGS)

 

2.Mixed QGS-quartz-muscovite-biotite-graphite schist (QMBGS) unit called INT or intermediate unit

 

3.Quart muscovite biotite graphite schist (QMBGS)

 

4.Quartz-biotite-garnet schist (QBGS)

 

QGS grades downward into INT, then into QMBGS, which in turn grades downward into QBGS. QMBGS is more highly metamorphosed than QGS and less metamorphosed than QBGS. In most places, the mixed QGS-QMBGS unit (INT) consists of interlayers of finer grained QGS with QMBGS layers containing medium to large muscovites and biotites, reflecting a gradual increase in metamorphic grade from the QGS to the QMBGS (Greenan, 2022).

In some places, QGS grades downward into QMBGS without interlayering of the two units. The contact between these two units is somewhat arbitrary and is taken as where the muscovites and biotites become much larger and more common than in the QGS and where the rock has larger, coarser foliations. This change is reflected in the Cg assays, with the QMBGS generally having much lower Cg grades than the QGS.

 

In some of the drill core, the transformation from QGS to QMBGS appears to have been caused by the introduction of a large number of pegmatites emplaced very close together. The heat from this process caused recrystallization and regrowth of the muscovites and biotites. The heat also caused remobilization and growth of the Cg flakes, giving rise to medium to very large Cg flakes in many of these zones. Cg grades are sometimes lower due to the pegmatites, while the flake size is larger.

 

Overall, metamorphism increases with depth. This may be caused by the depth of a lithological unit and/or regional metamorphism, or by a buried heat source below the QBGS (contact metamorphism). Near the bottom of some of the holes, the QBGS has gneissic intervals. These are suggested to be fingers/sills of a gneissic intrusive that may have caused the different metamorphic grades.

 

Metamorphic grade can also increase laterally, with a transition from QGS to INT to QMBGS. Changes such as these appear to be evidence of a contact metamorphic aureole, possibly from a buried amphibolite or other intrusive body. These types of changes, along with thrust faulting, help explain the apparent lack of horizontal and/or vertical continuity of the various lithologies in the cross sections. Increasing metamorphic grade from QGS to QMBGS also generally correlates with lower Cg values, indicating that the Cg was driven off by the metamorphism. In general, metamorphic grades increase from east to west in the Main Grid area. Kyanite and sillimanite increase closer to the large amphibolite intrusive that occurs to the east of the Main Grid area. These also increase closer to a postulated buried granitic intrusive that occurs on the southeast end of Line 05 in the Main Grid area (Figure 6-3).

 

There is no definitive correlation between the different iron oxides (jarosite, goethite, and hematite) and Cg mineralization. However, areas with more jarosite ± goethite generally occur above more pyritic unoxidized QGS. Quartz veins/veinlets that cut the foliations usually have more hematite than jarosite or goethite. Hematite is most common in and close to amphibolite sills and intrusives.

 

There appears to be at least two distinct generations of quartz veins.

 

1.White to light gray quartz veins 2 in. to 12 in. thick emplaced mostly along and parallel to foliations without causing contortion of the foliations. Since they mimic the foliations, in the Main Grid area they usually occur at low angles.

 

2.White, more massive quartz veins 2 in. to 24 in. thick cutting across the foliations at high angles, often with hematite on the selvages. These often cause contortions of the foliations and often appear to cause small-scale offsets in what appears to be a normal-fault sense of movement. These types of veins appear to be more common in proximity to the various amphibolite intrusives and cut both the amphibolites and the metasediments.

 

In addition to the quartz veins, there are two types of pegmatites found on the Project:

 

1.Fine to medium grained quartz-albite to albite-quartz pegmatites, sometimes with possible remobilized vanadium giving them a greenish color. This type of pegmatite generally occurs along foliations.

 

2.Medium to coarse grained albite-quartz pegmatites that are often argillically altered and occur in the upper plate of a postulated thrust fault. These pegmatites often cut across the foliations at a shallow to fairly steep angle. Thrusting is evidenced by slickensides along, or at a low angle to, foliations.

Technical Report Summary - December 1, 20226-6 

 

 

 

Larger Cg flakes often appear to be from remobilized carbon/graphite and are generally associated with/found in:

 

1.Fractures in quartz veins and pegmatites.

 

2.The margins of granitic sills, quartz veins, and pegmatites.

 

3.In the QMBGS unit near the QGS contact in and along the margins of the large muscovites and biotites, especially in areas with larger quantities of pegmatites.

 

4.In microfractures in the QGS in the sulfide zone.

 

In addition to larger Cg flakes occurring in the QMBGS unit, larger, coarser grained Cg flakes appear to occur more often in areas that have been more fractured, with the Cg occupying the fractures and microfractures, in particular in the QGS, INT, and QMBGS units. Quartz veins and pegmatites that have been fractured also often have larger Cg flakes occupying the fractures, including what looks like veinlets of graphite, some of which may be amorphous. Larger Cg flakes can also often occur on the edges of the pegmatites and quartz veins, providing more evidence of remobilization of the Cg. Further evidence of remobilized graphite is observed in the sulfidic portions of some of the core, where Cg flakes can be seen cutting across and/or causing embayments in pyrite. Good examples of this occur in drill hole AGC-F04 at 79.5 ft.

 

Granitic sills appear to have been one of the earliest episodes of intrusives and are sometimes cut by later pegmatites. The granitic sills appear to have been emplaced in thermal equilibrium with the metasediments as there are no visible alteration haloes on the selvages of the granitic sills. Granitic sills can range from 0.5 in. Up to 12 in. thick. Based on the relogging of the AGC holes, there appears to be a granitic body beneath the drill holes in the Main Grid area in the vicinity of holes AGC-H05, I06, and J05, continuing southwest close to drill hole AGC-I04 (Figure 6-3). In many cases, these are associated with increased Cg flake size and increased fracturing of the host rock. However, the granitic sills themselves are rarely cut by Cg veinlets or have Cg flakes in fractures.

 

In the Main Grid area, foliations generally strike 20˚ to 35˚ to the northeast, dipping at 10˚ to 45˚ to the southeast. The foliations generally flatten with depth. Steeper foliations appear to be related to a northwest directed thrust fault or, more accurately, zone of thrusting. The presence of steeper foliations on and near surface in the trenches and drill holes in the Main Grid, NX, SW Extension, Fixico Mine, HS-North, and HS-South areas also point to a thrust fault. In general, foliations flatten with depth, especially in the finer grained QGS layers.

 

This thrust fault extends from the SW Extension area through the Main Grid area and continues through the NX area, trends approximately 20˚ northeast from just west of hole AGC-15-L006 on its southwest end up to just west of AGC-15-G20 on the northeast end. This thrust is evidenced by fault/fracture zones in the drill holes near this proposed fault, along with highly contorted foliations and slickensides along the foliations. Much of the core exhibits slickensides along the foliations (which in outcrop often have shallow dips to the southeast), indicating subhorizontal (probably thrust-fault related) movement. These occur in the QGS in roscoelite-rich layers, and in Cg-rich and pyrite-rich layers. These often occur in multiple foliations close together, which indicates that the units slid over each another and over themselves like a deck of cards, with large quantities of small movement in many layers. In spite of the large books of muscovite and biotite, slickensides in the QMBGS unit have not been observed.

Technical Report Summary - December 1, 20226-7 

 

 

 

Highly contorted foliations furnish further evidence of thrusting. These occur more often in and near layers with slickensides, especially in areas with granitic sills, pegmatites, and quartz veins. The contortion of the foliations would help to take up the strain of thrusting. The siliceous nature of the various intrusives would prevent slipping, forcing them to contort in order to take up the strain of thrusting. Several of the drill pad cuts have highly contorted foliations that appear to indicate west-northwest directed thrusting. This occurs in areas where amounts of remobilized graphite along the contacts of the sills or veins with the country rock are not large.

 

The granitic sills, pegmatites, and the early generation of quartz veins extend parallel with and along the foliations and generally do not cut the foliations, except possibly at low angles. If the foliations are contorted, so are the quartz veins, pegmatites, and granitic sills. These indicate that the granitic sills, pegmatites, and early generation quartz veins were emplaced before the deformation and contortions of the foliations occurred. If the contorted foliations are related to thrust faulting, that means that the early quartz veins, pegmatites, and granitic sills were emplaced before thrust faulting occurred. Due to their brittle nature, only the quartz veins are shattered where they are highly contorted.

 

Pegmatites in the southeast part of the Main Grid area and in the Fixico Mine area are often of a different nature than those that occur to the north and west. This may partly be due to these occurring in the upper plate of the thrust fault, which may have encountered a different intrusive environment before thrusting occurred. These pegmatites are often larger/thicker, coarser grained, and often have clasts of the country rock (usually QGS) within them. They are also generally argillically altered and cut across the foliations of the QGS at shallow to moderately steep angles. These all indicate a more dynamic emplacement environment, possibly closer to an igneous source. Similar to the granitic sills, there is no visible evidence to thermal alteration along the contacts of the pegmatites with the country rock, indicating that they were in thermal equilibrium when the pegmatites were emplaced.

 

In the geologic literature, the graphite in the lithologic units at Coosa is believed to be stratabound and stratiform (Greenan, 2022). Near and within areas of thrust faulting at Coosa, the Cg appears to cut across the strata, but this may be due to the offsetting and stacking of the layers by thrusting.

 

Cg grades in the QGS are generally higher than in the INT, which usually has higher Cg grades than QMBGS, with almost no Cg in the QBGS, due to much higher temperatures driving off the graphite. Cg grades also appear to be higher in the NX, SW Extension, Fixico Mine, and HS areas than in the Main Grid area. These higher Cg grades correlate well with higher V-rich muscovite content but are not always related to each other. Note that most of the Main Grid area appears to be in the lower plate, underneath the thrust fault.

 

Grain size/coarseness of the QGS unit is usually larger in the upper plate of the thrust fault. V-rich mica grains/clots are also larger in the upper plate of the thrust. This may be related to the original protolith being coarser grained, and/or related to the depositional environment, wherein the upper plate portion of the QGS was deposited in an area with more vanadium in solution. Deformation within the QGS is also much more pronounced in the upper plate of the thrust fault, indicating that above the main thrust plane there is a zone of thrusting, with multiple layers stacked over each other. In the eastern portion of the Man Grid area and in the NX, SW Extension, Fixico, and HS areas, a generally larger graphite flake size is coincident with the larger grain size.

In addition to graphite, vanadium may be able to be recovered from the schists at the Project. Vanadium occurs in a V-rich mica called roscoelite. This is somewhat of a “field term” at Coosa, where the “roscoelite” does not necessarily have a sufficiently high concentration of vanadium to be “true” roscoelite. Roscoelite occurs in the QGS, INT, and QMBGS units, with lower to much lower amounts in the QMBGS unit. There is an approximately 50% correlation between the V and Cg grades, but higher Cg does not necessarily mean higher V, and vice versa. This may be due to vanadium being carried in solution under oxidizing conditions and deposited in anoxic environments where the graphite and graphite precursors would occur. Breaking out the different lithologies and oxidized versus reduced might show a higher V:Cg correlation in the reduced portions. The oxidized portions might be more problematic due to mobility of vanadium in oxidized environments, with the amount of remobilization/leaching of vanadium possibly dependent on the amount/strength of oxidation, the size of the V-rich muscovite flakes, and the type of (iron) oxides involved.

 

Although there does not appear to be a correlation between iron oxides and graphite grades, there does appear to be an inverse relationship between the amount of the various iron oxides and the amount of roscoelite. Areas with higher amounts of jarosite, goethite, and/or hematite often have lower amounts of roscoelite and/or the roscoelite has leached edges. This could be due to vanadium being very mobile in an oxidizing environment, with oxidation of pyrite ± pyrrhotite causing acidic groundwater that caused the vanadium to go into solution. This leaching of vanadium from oxidized schists at Coosa may partly be responsible for the V: Cg correlation being not higher than approximately 50%.

 

In the QMBGS, the roscoelite is often metamorphosed and remobilized into light to medium green glassy clots/layers (in the AGC logs, this was noted as “possible nephrite”). Westwater indicates that Harold Stowell of the University of Alabama and his students are working on thin sections that include this type of material to provide a definite identification of its mineralogy.

 

Some of the white clays that occur in the upper portions of the drill holes in zones with high Cg may be weathered and/or altered roscoelite. These white clays often have Cg in or on their margins. None of the other clays have this type of association. Harold Stowell and his students are examining thin section samples of some of this material to provide a more definitive identification.

 

There is a large amphibolite body in the northeast part of the NX area, near drill holes AGC-007, AGC-008, and AGC-009 and underlying proposed drill holes CD-3, CD-4, and NX-17. In general, this amphibolite appears to mimic the resistivity high on the airborne geophysical map. It should be noted that core recovery from some of these holes is not good and the few pieces of core in the boxes appear to be weathered, oxidized amphibolite, and some pieces are weakly magnetic. Figure 6-4 and Figure 6-5, below, show the conductivity low associated with the amphibolite and the outline of the amphibolite based on core photos, core, and reconnaissance surface mapping, respectively. Another amphibolite, possibly part of the same one mentioned above, occurs to the east, on the north side of the HS area, and forms outcrops along the county road.

 

The upper portion of hole AGC-15-K20 appears to be weathered amphibolite, often intruding into the QBGS, grading downward into highly contorted QBGS, often with gneissic textures. Hole AGC-009 begins in what appears to be weathered amphibolite, with an inverted stratigraphy below it, going from QBGS downward into mixed QMBGS-QGS (INT) and then into QGS. This inverted stratigraphy, coupled with the approximately 45° dips of the foliations on the surface caused by the thrust fault, may be the reasons that Alabama Graphite interpreted high angle tight isoclinal folds with repetition of beds in the geology of this area. A more plausible explanation of the geology is that the amphibolite in the area outlined on Figure 6-6 was originally much thicker and occurs as a sill or cap over the metamorphic package. This served as a heat engine to metamorphose the sediments, causing higher metamorphic grades near the contact, including kyanite and sillimanite, with decreasing in metamorphic grade away from the amphibolite. Note that this only applies to the metasediments underneath the amphibolite, as those on and near the lateral margins do not show a high degree of metamorphism. This may be due to the near vertical contact, which would have allowed heat to quickly escape and prevented higher grade metamorphism of the country rock.

The increasing metamorphic grade with depth may be an indication of a larger amphibolite or other intrusive body (possibly gneissic) at depth. The amphibolite exposed on the surface may be a plug or apophysis off of this intrusive. Mapping of the road cuts of the areas surrounding the amphibolite, working outward from the margins, to see if the metamorphic grade of the metasediments decreases away from the amphibolite, may help confirm this suggestion.

 

The intrusion of the amphibolite appears to have occurred after thrusting, as the QGS on the surface has quartz veins at or near the contact and is often clay altered on the margins of the amphibolite. Further away from the margins of the amphibolite, weak to strong acid leaching of the QGS occurs, with sometimes mostly silica and Cg remaining in the QGS (as seen in hole AGC-15-J11). This may have been caused by the oxidation of pyrite in reduced QGS, coupled with the high iron content of the amphibolite, forming sulfuric acid and leaching the QGS. This acid leaching is very subtle in outcrop and float and would require detailed surface mapping to try to define it on the surface.

 

In general, the amphibolite appears to have intruded into the QGS unit parallel with the foliations, following zones of weakness, and very rarely appearing to cut the foliations. In many cases, the amphibolite sills occur adjacent to/in contact with granitic sills and/or pegmatites. Larger bodies of amphibolite often have quartz veins within them and/or on their edges. Sills of the amphibolite within the QGS, as exposed in the cut for the pad for hole NX-17, do not appear to have been offset or deformed by thrusting, also indicating that the amphibolite was intruded after thrusting occurred.

 

There is very little to no thermal metamorphism in the QGS along the contacts with the amphibolite sills, granitic sills, or pegmatite sills. This indicates that these were all in thermal equilibrium when they intruded the metasediments. While this may sound contradictory compared to the proposed contact metamorphism related to the amphibolite mentioned above, the lack of alteration may be due to the relatively quick emplacement of the sills.

 

Besides the change in metamorphic grade from the QGS to QMBGS to QBGS, the most common evidence of metamorphism is conversion of roscoelite to kyanite or sillimanite. This can occur in the QGS, INT, and QMBGS units. In some places, the roscoelite appears to have been remobilized into thicker layers up to one to three inches thick with a somewhat porcelaneous to glassy texture. In some places, the change from mica to kyanite or sillimanite occurs in highly contorted foliations in or near proposed thrust planes, indicating that this change may be more related to local pressure and temperature changes than regional metamorphism. Increased sillimanite and/or kyanite are also associated with lower Cg grades.

6.4Mineralization

 

Graphite flakes occur as part of the rock forming minerals in the schists. They are often associated with disseminated pyrrhotite and minor pyrite. In places, the green vanadium bearing muscovite, roscoelite, also occurs. Minor late stage, straight-sided veinlets of cubic pyrite up to 10 mm wide with smectite clay cross cut the schistosity and pegmatites.

 

Graphite ores mined historically were almost entirely from the weathered zone (60 ft to 100 ft), partly because weathering is deep in this area and partly because the weathered rock could be gently crushed without blasting, liberating the graphite without significantly reducing the size of the larger flakes.

 

The oxide and transition zones were logged in core and modelled for resource estimation. The oxide zone is defined as the zone of total oxidation of sulfides to give an orange-red-brown color to core, and a much softer rock. The base of the oxide zone is often sharp and occurs over an interval of less than one foot. The transition zone is defined as the zone of partial oxidation of sulfides and the rock is significantly crumblier than the underlying reduced or sulfide zone. The top of the transition zone is marked by the first appearance of sulfides downhole, and the base is marked by the disappearance of iron oxides, and a marked increase in hardness. Generally, there is more oxidation on fractures and veins in this zone.

 

The main schist compositions and logging units defined by Westwater geologists (Figure 6-2) in drill core are as follows:

 

Quartz-graphite schist (QGS): This schist is both finer grained and better laminated than the QMBGS unit. The color varies from dark gray to black. Contorted foliation and pegmatites are less common. Pyrite and pyrrhotite are both finer grained and more abundant than in the QMBGS unit and form laminae parallel to foliation. Graphite is more abundant in this unit, with grades higher than 1% Cg.

 

Mixed QMBGS/QGS (INT): The QMBGS and QGS are commonly interbedded at a centimeter scale forming a mixed unit with graphite grades higher than 1% Cg.

 

Quartz-muscovite-biotite-graphite schist (QMBGS): This schist is medium to coarse grained in texture and is characterized by large porphyroblasts of muscovite. The color varies from medium gray to dark gray-green. It is moderately foliated and commonly contorted, with lenticular pegmatites parallel to foliation. Pyrite and pyrrhotite are common accessory minerals and occur as large, disseminated grains. Sillimanite fibers have been observed. Graphite flakes are generally coarse in this unit, although the average carbon content is generally less than 1% Cg.

 

Quartz-biotite-garnet schist (QBGS): This unit is subordinate to both the QMBGS and QGS units. It is medium grained and medium to dark gray-green in color. The garnets are usually fine grained with a diameter of about one millimeter, but in places are up to 5 mm to 10 mm. The garnets are light pink in color, suggesting a high manganese (spessartine) content. Foliation is irregular with abundant pegmatites. Pyrite is sparse. Graphite is sparse and grades are less than 1% Cg.

6.5Deposit Types

 

Graphite deposits occur in three forms: flake graphite, vein graphite, and amorphous graphite. These are described by Mitchell (1993):

 

Graphite generally occurs as a result of metamorphism (regional or contact) of organic matter in sediments. Flake graphite is assumed to be derived from fine grained sediments rich in organic matter. As metamorphic grade increases, carbonaceous material converts to “amorphous” graphite. Flake graphite forms from its amorphous precursor at or beyond amphibolite grade metamorphism (Landis, 1971). Vein graphite is assumed to form by partial volatilization of graphite and subsequent recrystallization during regional granulite and/or charnockite facies metamorphism. Amorphous graphite is generally considered to have originated by thermal or regional metamorphism of coal or carbonaceous sediments.

 

Positive vanadium and nickel anomalies and negative boron anomalies are possible signatures for graphite if geochemical survey data are available. The presence of sulphides and trace amounts of uranium may be an indicator.

 

Landis (1971) tentatively concluded that graphite formation is primarily dependent on metamorphic temperature and forms above 750°F (400°C), with pressure and variation in starting material constituting secondary controls.

 

The Coosa graphite deposits are flake graphite deposits in high grade metamorphic rocks. They are associated with anomalous vanadium, including the vanadium-mica roscoellite, and nickel, as well as other elements.

7.0Exploration

 

7.1Exploration

 

Prior to Westwater acquiring the property in 2018, Alabama Graphite, then a subsidiary of AGC, conducted several surface exploration campaigns between 2012 to 2015. Due to the lack of outcrop and dense vegetation, the exploration techniques used were rock sampling in channels mainly along road cuttings, trenching, geophysics, and drilling. Westwater has conducted additional in-fill/delineation diamond drilling (DD) in the Project area during 2021 and 2022. The Company has also conducted a geochemical sampling program using available core and trench material to determine the presence and intensity of vanadium mineralization at the Project.

 

7.1.1Channel Sampling

 

Channel sampling was carried out initially by AGC close to the Coosa target and later over a large area around it. A total of 1,025 channel samples were reported taken at 328 locations in 2012 to 2014, as shown in Figure 7-1. This comprised 115 samples in 2012 (a further 113 samples had unreliable analyses and the results were discarded), 268 samples in 2013, and 642 samples in 2014. One to sixteen samples would be taken at each sample locality, with an average of 3.125 samples per locality. The distribution of sample locations was not systematic due to the lack of rock outcrop and dense vegetation. Samples were typically collected along road cuts where bed rock was exposed. Small trenches were excavated by hand with a pickaxe and shovel, and ranged from two to three inches in depth and 5 ft to 35 ft in length. The trenches were typically cut perpendicular to the bedrock foliation to provide a representative sample of the outcrop and expose structural features such as foliation.

 

Before the sample was collected, a global positioning system (GPS) was used to record the location of the start of the trench and all measurements were recorded in a field notebook and later tabulated into a Microsoft (MS) Excel database. Material collected from the trench was placed in a sample bag and labeled.

7.1.2Trenching

 

A program of mechanical trenching was carried by Alabama Graphite in the winter of 2014 using an excavator. A total of 30 trenches were dug with a total length of 10,790 ft. Of these, nine trenches with a total length of 3,600 ft were dug in the Coosa resource estimate area and used in the database for the resource estimate, and another 21 trenches with a total length of 7,190 ft were dug on exploration targets.

 

The objective was to cut long trenches across the strike of the graphite mineralization in the grid area to infill between DD holes and demonstrate continuity of near surface mineralization. Trenches were also dug on geophysical exploration targets away from the drill grid. The average depth of the trenches was 4 ft to 5 ft with a maximum depth of 8 ft. The trenches were backfilled and revegetated as soon as they had been sampled.

 

The trenches were treated as low angle drill holes for surveying, sampling, logging, and the database. The starting point (collar) of the trench was surveyed by GPS, and measurements of azimuth and inclination were taken by compass and tape at 25 ft. These were treated as downhole directional surveys to plot the trench. Samples were surveyed by compass and tape to give length, azimuth, and inclination. Samples were taken continuously in 5 ft lengths from the base of the wall of the trench using a geological hammer and a plastic core box as a receptacle. A 20 lb to 25 lb bulk composite sample was also collected on 25 ft lengths for metallurgical test work.

 

7.1.3Geophysics

 

7.1.3.1Surface

 

Alabama Graphite carried out two trial ground geophysical surveys. A GEM2 ground frequency domain EM survey was carried out using a GEM2 instrument along roads and had a depth of penetration of 50 ft. In addition, a ground time-domain electromagnetic (TDEM) survey was tested but not found to be useful due to the high contrast in the EM response between the oxide and reduced (unweathered) zones.

 

7.1.3.2Airborne

 

A helicopter borne magnetic, radiometric, and TDEM survey was carried out by the contractor Prospectair (Québec) in March 2014 over exploration areas surrounding the Coosa resource estimate area (Figure 7-2). Data processing and interpretation were completed by Dubé & Desaulniers Geoscience (Québec) and are described in a report by Dubé (2014).

 

The survey covered two areas named Coosa North, centered on the Coosa Main Grid area, and Coosa South, over the Bama project in Chilton County, which is not described further in this TRS. A total of 554 line miles were flown on Coosa North on lines oriented 126° with a 328 ft line spacing, and perpendicular control lines spaced at 3,280 ft. The average height above the ground of the helicopter was 291 ft. Graphite targets were defined based on high conductivity from the TDEM survey (graphite and/or sulfides) combined with magnetic lows (no pyrrhotite), as shown in Figure 7-2. A number of these targets were followed up by channel sampling, trenching and, in some cases, drilling.

7.1.4Vanadium

 

In early 2018, Westwater’s technical staff carried out a review of historical data and geologic information derived from previous graphite exploration drilling and surface trenching programs at the Project to determine the potential for the presence of substantial vanadium mineralization. This work identified significant potential for the discovery of vanadium mineralization in the Project area.

 

In late 2018, Company personnel carried out an extensive geochemical sampling program, collecting nearly 2,000 samples from many previously completed drill holes and trenches, to determine the presence and intensity of vanadium mineralization at the Project. The laboratory analytical results of this sampling program outlined widespread and strong vanadium mineralization in very close association with flake graphite mineralization at numerous localities within the Project area.

 

The vanadium mineralization at the Project occurs principally as the mineral roscoelite, a medium to dark green mica mineral that has been a global source for vanadium for more than one hundred years. In addition to the presence of widespread vanadium mineralization in drill hole and trench samples, impressive zones of vanadium mineralization have been outlined in surface exposures at several locations within the Project area.

 

7.2Exploration Target

 

In late 2018, Company personnel carried out an extensive geochemical sampling program, collecting nearly 2,000 samples from many previously completed drill holes and trenches, to determine the presence and intensity of vanadium mineralization at the Project. The laboratory analytical results of this sampling program outlined widespread and strong vanadium mineralization in very close association with flake graphite mineralization at numerous localities within the Project area.

 

Due to the limited number of assays collected and wide-spaced drilling between holes sampled for vanadium, all the vanadium pentoxide (V2O5) is considered to be exploration potential. Vanadium potential tonnage and grade are currently estimated to range from 21.0 Mst to 67.0 Mst and 0.19% V2O5 to 0.13% V2O5, respectively. SLR notes that the potential quantity and grade are conceptual in nature, there has been insufficient exploration to define a Mineral Resource, and it is uncertain if further exploration will result in the target being delineated as a Mineral Resource.

 

7.3Drilling

 

Core DD on the property is the principal method of exploration and delineation of graphite mineralization after initial targeting using rock sampling and geophysical surveys. Drilling can generally be conducted year-round on the Project.

 

As of the effective date of this TRS, Westwater and its predecessor companies have completed 45,715 ft of drilling in 236 holes (181 DD = 33,117 ft, 24 Sonic = 1,303 ft, 31 Trenches = 11,295 ft) over the Project, as summarized in Table 7-1 and illustrated in Figure 7-3.

Six drilling campaigns have been carried out by Westwater and its predecessor AGC at the Project from 2012 to 2022. Drilling focused in the NX and Main Grid areas, however, exploration drilling has also been completed on the remaining three areas. Between 2012 and 2015, 171 drill holes totaling 40,164 ft were completed by Alabama Graphite. From 2021 to March 15, 2022, Westwater completed 65 DD holes totalling 5,551 ft.

 

In 2021, all drill core, including core previously collected by Alabama Graphite, was transported from drill sites and from Alabama Graphite’s prior office in Sylacauga to the Westwater core facility located in Kellyton, Alabama, via pick-up. Core was logged, photographed, sampled, and stored in core racks at the core logging facility.

 

Of the 236, 205 holes totaling 39,434 ft were drilled in the Coosa target area and are used in the database for the Mineral Resource estimate. The remaining 31 holes totaling 6,281 ft are exploration holes drilled in the HS-North area (13) or are isolated single holes (18) outside the Coosa block model boundaries were excluded from the resource estimation.

 

7.3.1Alabama Graphite

 

Alabama Graphite conducted four drilling programs at the Project between 2012 and 2015 comprising 171 drill holes totaling 40,164 ft.

 

7.3.1.12012 Diamond Drilling (Stratigraphic Lines)

 

The first program of diamond drilling was carried out between September 27, 2012, and October 23, 2012, and consisted of two northwesterly trending fences of six holes each for a total of 6,003 ft (holes AGC-001 through AGC-012). All fence holes were drilled at an inclination of -50° perpendicular to the stratified graphite horizons to gain information regarding the stratigraphy and graphite distribution. The two fences were approximately 3,000 ft to 3,800 ft apart, with hole spacing averaging 500 ft. The fence holes were core holes of HQ (2.5 in.) diameter and were drilled to a nominal depth of 500 ft.

 

7.3.1.22012 Diamond and Sonic Drilling (Resource Grid)

 

The second drilling program was carried out between October 23, 2012, and December 21, 2012, and consisted of 57 vertical holes drilled on a 200 ft x 200 ft grid in the Main Grid area for a total of 14,415 ft. The holes were numbered by the grid location and included holes AGC-A04 to AGC-J09. The grid drilling was a combination of sonic core and HQ core. Diamond drilling gave low core recovery (<50%) in the upper weathered zone so a sonic drill was used to drill core through the weathered zone and set casing for the HQ diamond core drill. This method proved to be very effective due to the approximately 100% core recovery from the sonic drill, however, in some holes there is a gap of up to 10 ft in sampling between the end of the sonic core and the start of the diamond core.

 

7.3.1.32014 Sonic Drilling for Exploration

 

Twenty-four sonic holes were drilled in summer 2014 for a total of 1,303 ft numbered AGC-10S, AGC-12S, AGC-14-K03S, and AGC-14-01S to AGC-14-21S. The core diameter was HQ.

 

Eleven of these holes were located in the Coosa resource area and are included in the database for the Mineral Resource estimate. Of these eleven, holes AGC-14-010S and AGC-14-012S were re-drilled in the upper parts of diamond drill holes AGC-010 and AGC-012, but are treated as separate drill holes as they were not pre-collars; three holes (AGC-14-13S, AGC-14-18S, and AGC-14-20S) were deepened by diamond drilling in 2015 (respectively holes AGC-15-H14, AGC-15-I19, and ACG-15-I21); and one hole was not deepened and is only a sonic hole (AGC-14-K03S).

The other 13 sonic holes drilled in 2014 are exploration holes to test geophysical anomalies away from the Coosa resource area and were not used in the database for the Mineral Resource estimate.

 

7.3.1.42015 Diamond Drilling Program

 

The 2015 drilling program was designed to extend the Main Grid and resource to the north and south, with the emphasis on the oxide and transition zones. A different drill contractor was used, Dycus Diamond Drilling LLC (3D Drilling) of Wytheville, Virginia, with two truck mounted Longyear 38 drill rigs. The contractor was chosen for their ability to achieve high core recoveries of almost 100% in the oxide and transition zones by drilling at a slower rate with less weight on the bit. The core diameter was HQ. The three deeper exploration holes were reduced to NQ (1.9 in.) diameter at 150 ft depth.

 

A total of 37 diamond drill holes for 5,333.5 ft were drilled on the Coosa resource grid in 2015, of which three holes totaling 142.0 ft were pre-collared by sonic drilling in 2014. The holes were numbered by the year and grid location and are AGC-15-E003 to AGC-15-O006.

 

In addition, nine holes for 1,755 ft were drilled on two exploration targets in 2015, Fixico Mine (holes AGC-15-FIX01 to AGC-15-FIX03) and Holy Schist (holes AGC-15-HS01 to AGC-15-HS06). One of these was pre-collared by sonic drilling in 2014. These holes were not used in the database for the Coosa Mineral Resource estimate.

 

Downhole surveys of the diamond drill holes were taken by the drilling company with a Reflex Instruments EZ Shot Survey tool (all 2012 holes, 22 of the 2015 holes) or a Multishot tool (24 of the 2015 holes). The instruments were adjusted for the local magnetic declination of 3.5° west and recorded the azimuths relative to grid north. Measurements were made at the end of the hole and, in the deeper holes, at a midway depth. Downhole surveys were not carried out on the sonic drill holes as they were short and vertical, and most were pre-collars for diamond drill holes.

 

Drill collars are capped by plastic pipe with a cap and cemented in place. Collar locations were surveyed with a high precision 2005 Trimble GeoXM GPS unit with submeter accuracy. The collars of the 2014 sonic holes were surveyed with a handheld Garmin GPS unit with lower accuracy 3 m to 5 m (10 ft to 16 ft). The datum used was NAD83 UTM Zone 16N in meters.

7.3.2.12021-2022 Diamond Drilling Program

 

From late May 2021 to mid-March 2022, Westwater completed 5,551 ft of drilling in 65 drill holes. More than 95% of the footage drilled was NQ. The drilling campaign had three main objectives: confirmation of historic drilling results, infill drilling to test the continuity of the Cg mineralization, and collection of drill core for vanadium geochemical assessment.

 

No downhole surveys were completed due to the shallow depth of drilling, with an average depth of 85 ft.

8.0Sample Preparation, Analyses, and Security

 

8.1Sample Preparation and Analysis

 

Information in the following sections contained in this TRS have been derived, and in some instances extracted, from the subsequent drilling programs discussed above and documentation and standard operating procedures (SOP) supplied to SLR by Westwater for review.

 

8.1.1AGC Channel Samples 2012 Preparation and Analysis

 

AGC initially used Mineral Labs, Inc. (Mineral Labs) of Salyersville, Kentucky (not accredited) and Société Générale de Surveillance (SGS) at Lakefield, Ontario (ISO/IEC 17025:2005 certified) for sample preparation and carbon analyses of channel samples taken in 2012 and for the first drill hole, AGC-001C. Both laboratories are independent of AGC.

 

The first batch of 113 channel samples was prepared by Mineral Labs at their laboratory in Birmingham, Alabama, and analyzed for carbon by the loss on ignition (LOI) method at their laboratory in Salyersville. These results were subsequently found to be erroneous and too high and were discarded.

 

The second batch of 115 channel samples was prepared and analyzed for carbon by the LECO method by SGS Lakefield and were shown to be reliable by secondary check analyses at ALS Minerals in Elko, Nevada (ISO/IEC 17025:2005 certified/accredited). The sample pulps were also analyzed at Mineral Labs, and comparison with the other laboratories showed that the Mineral Labs assays were unreliable.

 

Core from the first drill hole, AGC-001C, was submitted to SGS at their laboratory in Birmingham, Alabama for preparation. The pulps were sent to SGS Lakefield for carbon analysis. The marble blank samples were reported to contain greater than 11% Cg because of inadequate acid removal of carbonate carbon prior to the LECO analysis. In addition, it was found that the sample preparation laboratory in Birmingham had only prepared a few pieces of core from each bag instead of the entire sample. The SGS analyses of hole AGC-001C were not used. After these failed results, the unprepared samples, rejects, and pulps were retrieved from the two SGS laboratories, recombined by AGC, and submitted to ALS Minerals for preparation and analysis.

 

8.1.2AGC 2012–2015 Preparation

 

All further sampling from 2012 through 2015 samples was prepared and analyzed either by ALS Minerals in Elko, Nevada and Vancouver, British Columbia (ISO 9000:2008 registered and ISO 17025 accredited in North America) or by Activation Laboratories Ltd. (Actlabs) in Ancaster, Ontario (ISO 9000:2008 registered and ISO 17025 accredited, as well as accredited to CAN-P-1579, which is specific to mineral analysis laboratories). All three laboratories are independent of AGC and Westwater. ALS Minerals was used as the primary laboratory for the 2012 and 2013 drill programs and Actlabs as the secondary laboratory; this was reversed for the 2014 and 2015 drilling, trenching, and sampling programs.

 

8.1.2.1ALS Minerals

 

Samples were prepared by ALS Minerals at their laboratory in Elko, Nevada. The sample preparation procedure was to log the samples into the tracking system and add a bar code label (procedure code LOG-22), weight the samples (code WEI-21), dry them at high temperature of up to 120°C (code DRY-21), fine crush by jaw crusher to greater than 70% passing -2 mm (code CRU-31), split off 1,000 g using a riffle splitter (code SPL-21), and pulverize the 1,000 g split to greater than 85% passing 75 microns (200 mesh) in a ring and puck style grinding mill (code PUL-32). The entire sample preparation method is referred to by ALS Minerals as code PREP-31B.

8.1.2.2Actlabs

 

Samples were prepared by Actlabs at their laboratory in Ancaster, Ontario. The sample preparation procedure was to log the samples into the tracking system and add a bar code label, weight the samples, dry them at 60°C, crush the entire sample by jaw crusher to greater than 90% passing 10 mesh (1.7 mm), split off 250 g using a riffle splitter, and pulverize the split to greater than 95% passing 150 mesh (105 microns) in a mild steel ring and puck style grinding mill. The sample preparation method is referred to by Actlabs as code RX1.

 

8.1.3AGC 2012–2015 Analysis

 

8.1.3.1ALS Minerals

 

ALS Minerals shipped the sample pulps from Elko, Nevada, to their laboratory in Vancouver, British Columbia for analysis. A 1 g subsample of the sample pulp was analyzed for total carbon by sample combustion in a LECO induction furnace at high temperature which generates carbon dioxide. This is quantitatively detected by infrared spectroscopy and reported as percent carbon, with a range of detection of 0.01% to 50% C (code C-IR07). Inorganic carbon (carbonate) was analyzed by carbon dioxide (CO2) coulometry, with a range of detection of 0.2% to 15% CO2 (code C-GAS05). The procedure is to acidify the sample with perchloric acid (HClO4) in a heated reaction vessel to evolve free carbon dioxide. This is subsequently transferred to a CO2 coulometer using a carbon-free gas, where the CO2 is quantitatively absorbed and reacts with monoethanolamine in the presence of an indicator that fades in color with increasing CO2 concentration. The color change is detected by a photo-cell and is used to determine the amount of CO2 in the sample. Carbon is calculated from carbon dioxide and the results are rounded to two decimal points and one decimal point respectively. Check calculations often show variation of ±0.01% carbon due to rounding.

 

The sample weight and results for C (C-IR07), C (C-GAS05) and CO2 (C-GAS05) were reported to AGC on MS Excel spreadsheets and in Certificates of Analysis in secure Adobe Acrobat file format, transmitted by email and available on a secure internet sample tracking site called Webtrieve™.

 

Graphite carbon was calculated by AGC by subtracting inorganic carbon from total carbon. This assumes that the only other form of carbon present in the samples, other than graphite carbon, is contained within carbonates.

 

Multi-element analysis was carried out for one entire drill hole (AGC-010) by ALS Minerals at their Reno, Nevada laboratory. The samples were analyzed for 53 elements by aqua regia digestion and ICPMS analysis (method code ME-MS41L).

 

8.1.3.2Actlabs

 

Actlabs analyzed graphitic carbon on 0.5 g samples in an Eltra resistance or induction furnace with measurement by infrared spectrometer (method code 5D-C Graphitic Infrared). The samples were subjected to a multistage furnace treatment to remove all forms of carbon with the exception of graphitic carbon, with no acid digestion required. The samples were heated to 1,000°C in nitrogen in a resistance or induction furnace to burn off CO2 in carbonate and any organic carbon, leaving graphite carbon behind. The residue was then combusted in an oxygen environment to oxidize the graphite to determine the graphite content. The laboratory report graphite carbon (C-Graph) with a lower limit of detection of 0.05%. The sample weight and results for Cg were reported to AGC on MS Excel spreadsheets and in Certificates of Analysis in Adobe Acrobat file format.

8.1.4Westwater 2021-2022 Analysis

 

During 2021 and 2022 drilling programs, Westwater continued to use Actlabs as its primary laboratory with secondary checks being completed by SGS.

 

8.1.4.1Actlabs

 

Samples were prepared by Actlabs at their laboratory in Ancaster, Ontario. The sample preparation procedure was to log the samples into the tracking system and add a bar code label, weigh the samples, dry them at 60°C, crush the entire sample by jaw crusher to greater than 90% passing 10 mesh (1.7 mm), split off 250 g using a riffle splitter, and pulverize the split to greater than 95% passing 150 mesh (105 microns) in a mild steel ring and puck style grinding mill. The sample preparation method is referred to by Actlabs as code RX1.

 

8.1.4.2SGS

 

Analysis for graphitic carbon was carried out by SGS in accordance with its procedure for graphitic carbon determination in ores, concentrates, and metallurgical test products by hydrochloric acid leach and combustion infrared (IR) detection.

 

A weighed sample is roasted in oven at 500 C for one hour to remove all organic carbon. Carbonate carbon is then leached/evolved using HCl. The sample is then dried to remove the chlorides. The residue is mixed with metal accelerators and placed in the LECO IR combustion system. The residual carbon is taken as graphitic carbon. With high grade carbon, samples are wetted with methanol prior to acid addition.

 

Samples higher than 30% graphitic carbon are analyzed on the SC632 instrument. The SC632 uses high temperature combustion followed by IR detection to determine concentrated carbon content in a wide variety of organic materials as well as some inorganic materials such as soil, cement, and limestone.

 

8.2Bulk Density

 

A total of 263 specific gravity measurements were carried out by ALS Minerals at their laboratory in Elko, Nevada, in 2013 on three-inch to five-inch (7.6 cm to 12.7 cm) samples of split core provided by AGC from several holes from the 2012 program. The holes were selected to ensure representability of different rock types. A further 12 determinations were made by ALS Minerals in 2015 on samples from the oxide and transition zones in the 2015 drill program. Seven check specific gravity determinations were made by Actlabs in September 2015.

 

During the 2021-2022 Westwater drilling campaign an additional 121 bulk density measurements were sent to Actlabs with 89 of the measurements taken within the oxide horizon (Table 8-1).

 

At ALS Minerals, bulk density was determined after wax coating the sample (ALS Minerals method OA-GRA08n) while at Actlabs the specific gravity was determined without wax coating (code Specific Gravity Core).

8.3Quality Assurance and Quality Control

 

Quality assurance (QA) consists of evidence to demonstrate that the assay data has precision and accuracy within generally accepted limits for the sampling and analytical method(s) used in order to have confidence in a resource estimate. Quality control (QC) consists of procedures used to ensure that an adequate level of quality is maintained in the process of collecting, preparing, and assaying the exploration drilling samples. In general, QA/QC programs are designed to prevent or detect contamination and allow assaying (analytical), precision (repeatability), and accuracy to be quantified. In addition, a QA/QC program can disclose the overall sampling-assaying variability of the sampling method itself.

8.3.1AGC 2012–2015 Drilling

 

Between 2012 and 2015, AGC had a comprehensive QA/QC program for trench and drill core samples that met the best practices guidelines within industry standards. QA/QC samples were not inserted in the channel samples as these are not used for resource estimation.

 

AGC inserted one coarse blank in every 20 samples and took one field (core) duplicate in every 20 samples, giving approximately 10% QC samples. No certified reference materials (CRM) were available commercially for graphite carbon for the 2012 to 2014 programs. For the 2012 drill programs, AGC monitored the laboratory’s internal standard data.

 

In 2015 AGC, established the use of two CRM and inserted one CRM in every 20 samples in the 2015 drill program.

 

After the individual drill programs were complete, a replicate (check) analyses were made of approximately 10% of all samples at the second laboratory.

 

8.3.2Westwater Resources 2021–2022 Drilling

 

Since acquiring the property in 2018, Westwater has developed a comprehensive QA/QC program for drill core sample. The program continues the procedures previously established by AGP and meets the best practices guidelines currently used within the industry.

 

Westwater geologists insert at least one CRM and one duplicate for each hole, even if they are less than 100 ft deep (industry standard of 5% would mean one standard or one blank, and one duplicate per 100 ft, using a five foot sample interval).

 

The core samples are placed in plastic bags that are wire-tied shut, with five samples put into a rice bag, which are then put into wooden shipping boxes. The standards and blanks are also placed into plastic bags, similar to the core samples, but each standard and blank will be double bagged before being put into the rice bags with the other samples in order to help prevent confusion at the laboratory as to placement of the standards and blanks in the sample stream.

 

Certified Reference Materials (CRM)

 

The insertion of CRM, as mentioned above, will be randomized as to which standard is used and when they are inserted in the sample stream. To increase randomization and checks on the laboratory, standards will occasionally be inserted after blanks in the sample stream. Exceptions to the randomization include:

 

Occasionally standards will be inserted after visually high grade samples to provide a further check on the laboratory.

A standard close to the mining cut-off grade of 2% Cg will be inserted after some of the samples that visually appear to contain approximately 2% Cg.

Drill hole numbers were removed from corresponding sample numbers which provided another quality control check on the laboratories.

Technical Report Summary - December 1, 20228-5 

 

 

 

Blanks

 

The drill holes will be cut and sampled in the order that they were drilled. Because all of the planned holes at Coosa are less than 120 ft, multiple holes will be submitted to the laboratory at the same time. One blank of 50 g (two envelopes) will be inserted into the sample stream at the beginning of each hole, and one blank will be inserted at the end of the group of holes to be submitted at the same time. Other blanks (at least one per hole) will be inserted after a randomly selected visually high grade interval.

 

Duplicates

 

Duplicates should be taken in a more orderly fashion, at least one every ten samples, or at least one per hole even for holes less than 50 ft deep. These should include both visually high-grade and near cut-off grade samples to provide more certainty as to the assay results

 

8.3.3Certified Reference Materials

 

Results of the regular submission of CRMs are used to identify issues with specific sample batches, and biases associated with the laboratory. Results of the CRM sample analyses are plotted monthly in control charts with upper and lower limits of the acceptable values and the certified value.

 

8.3.3.1AGC 2012 Drill Program

 

No CRMs were available commercially for graphite in order to maintain an independent control. Instead, the internal standards used by the laboratory, ALS Minerals, were plotted. Four standards, with a range of carbon grades, were used routinely. The recommended values and upper and lower limits (defined as two standard deviations from the recommended value or the 95% confidence limits (P95)), as supplied by ALS Minerals, are listed in Table 8-2. These samples were manufactured by CANMET Mining and Mineral Services Laboratories, Ottawa, Canada as part of the Canadian Certified Reference Materials Project (CCRMP). These samples are certified for other elements and carbon is uncertified and is given as an “informational value”, “provisional value” or “approximate value”. Plots of the results of total carbon analyses by sample are shown in Figure 8-1 through Figure 8-4. The results are within the upper and lower confidence limits and show no trends or drift with time, thus indicating that the analyses have good precision and accuracy.

8.3.3.2AGC 2015 Drill Program

 

AGC had two CRM made by Actlabs in 2015 using coarse rejects of oxidized graphite schist from Coosa trench samples. The samples were pulverized, mixed, and homogenized, and 10 samples of each were analyzed at four laboratories (Actlabs, SGS, ALS Minerals, and Acme), from which the mean and standard deviation were calculated (the Acme data was not used as they use a different assaying method and digestion which gave a different mean and standard deviation). The recommended values are shown in Table 8-3.

 

The CRM results are monitored using control charts which are graphs with sample number or time on the x-axis and values on the y-axis. There are horizontal lines for the recommended mean value (green), and ±2 (yellow) and ±3 (red) standard deviations (SD). CRM values within ± 2SD are accepted; an isolated sample above ± 2SD but below ± 3SD is acceptable but is a warning; two consecutive samples above ± 2SD are rejected; and any sample above ± 3SD is rejected.

 

Zscore plots of the results of the Cg analyses by sample (time) is shown in Figure 8-5. The results are acceptable and show no trends or drift with time and indicate that the analyses have good precision and accuracy.

8.3.3.3Westwater 2021-2022 Drill Program

 

Westwater obtained four CRMs certified for carbon and one blank from CDN Resource Laboratories, Ltd. (CDN), located in Langley, British Columbia, Canada to account for different grade ranges (Table 8-4).

A total of 113 CRMs were inserted in the 2021-2022 sampling analysis, representing an insertion ratio of 10.0% considering all the samples. SLR received the CRM results, prepared control charts, and analyzed temporal and grade trends. Figure 8-6 presents the results for the Std 1 through Std 4 CRMs and indicates moderately good precision of the laboratory for STD 2, STD 3, and STD 4 and only small low bias in some cases. However, approximately 56% of STD 1 are outside the lower and upper limits of ±2SD. One sample from STD 2 is outside ±2SD.

 

Westwater did not rerun any additional checks on the failed batches and the cause of the STD 1 failures is suspected to be poor homogeneity in the standard sample quality. SLR is of the opinion that the STD 1 results are not materially impacting the Mineral Resource estimate or have relevance for this TRS but recommends that Westwater check and/or remove STD 1 for future assay analysis.

8.3.4Blanks

 

Blank material is used to assess contamination or sample-cross contamination during sample preparation and to identify sample numbering errors.

 

8.3.4.1AGC 2012 Drill Program

 

Coarse blanks were inserted in the drill and trench samples at approximately one every 100 ft (30 m), which equals one in every twentieth sample (approximately 5%).

 

Local marble was initially used as a blank but reported high C in LECO analyses because of problems with incomplete dissolution of carbonate. The blank was then changed to diorite in the form of coarse rock chips of 1 in. to 2 in. (2.5 cm to 5.1 cm) size bought as landscape rock from a local hardware store. Neither of these samples were analyzed previously for carbon or other elements. The diorite blank was introduced together with the marble blank from hole AGC-002C, and diorite was used exclusively from hole AGC-007C onwards. A total of 18 marble blanks and 221 diorite blanks were analyzed out of a total of 3,856 unknown drill samples in the 2012 drill programs (6.2% total blanks including 5.7% diorite blanks; note that the total unknown samples analyzed was higher and some have been eliminated from the database due to overlap between core samples and sonic samples). The diorite blanks are plotted in Figure 8-7 with reference lines at the lower limit of detection (0.01%), and five and ten times the lower limit of detection (LLD), 0.05% and 0.10%, respectively. Eleven samples (5% of the blanks) are greater than 0.10%, including four samples (1.8%) above 0.20% Cg, with values of 0.23%, 0.37%, 1.35%, and 1.91% Cg, which may be due to contamination, sample switches, or mislabeling.

8.3.5Duplicates

 

Duplicate samples are used to monitor preparation, assay precision, and grade variability as a function of sample homogeneity and laboratory error.

 

8.3.5.1AGC 2012 Drill Program

 

One field (core or trench) duplicate was collected approximately every 100 ft (30 m), which equals one in every twentieth sample (approximately 5%).

 

Core duplicates were taken by cutting the normal half core sample lengthwise to give two one-quarter core samples which were submitted for analysis as original and subsequent duplicate. These samples are half of the weight of normal half-core samples, which may thus introduce greater inhomogeneity than average. Trench duplicates were made by taking another sample along the same channel as the original.

 

A total of 160 pairs of field duplicates were analyzed out of a total of 3,856 unknown drill samples (4.1%) from the 2012 drill programs. The results are shown in a scatter plot in Figure 8-11 and in a plot of relative difference versus original value in Figure 8-12. These show that 91% of the duplicates are within ±20% of the average. The overall correlation is close to unity with scatter distributed evenly on either side, interpreted as geological heterogeneity, and there is no systematic bias. The average of the original samples is 1.86% Cg, and the duplicates is 1.86% Cg, with a relative difference of -0.23%.

Figure 8-13 presents the results of the analyses for the 39 pairs of field (trench channel) duplicates from the 2014 trenching program included in the Resource Estimate. This shows that 87% of the duplicates are within ±20% of the average. This is slightly lower than the core samples and is a function of greater sample variability in trench channels. The overall correlation is close to unity with scatter distributed evenly on either side, interpreted as geological heterogeneity, and there is no systematic bias. The average of the original samples is 2.26% Cg, and the duplicates is 2.31% Cg, with a relative difference of 2.26%.

8.3.5.2AGC 2015 Drill Program

 

A total of 61 pairs of field duplicates were analyzed out of a total of 1,404 drill samples (4.3%) from the 2015 drill program. The results are shown in a scatter plot in Figure 8-14 and in a plot of relative difference versus original analysis in Figure 8-15. This shows that 95% of the duplicates are within ±20% of the original, with three outliers. The overall correlation is close to unity with scatter distributed evenly on either side, interpreted as geological heterogeneity, and again there is no systematic bias. The average of the original samples is 2.57% Cg, and the duplicates is 2.61% Cg, with a relative difference of 1.5%.

 

It is concluded that the duplicate core samples show geological variability but there is no systematic bias, and the relative difference of the average grade of all originals and duplicates is very low, i.e., the average values are almost identical.

8.3.6Secondary Laboratory Check

 

8.3.6.1AGC 2012–2015

 

AGC carried out replicate analyses of a complete drill hole, AGC-03C, early in the drill program, and of 11.4% of samples from all drill holes after drilling had been completed.

 

AGC reanalyzed all samples from hole AGC-03C at a second laboratory in the early stages of the drill program. The preparation was carried out by a local laboratory which split the sample pulp into two, hence these are replicate analyses (same pulp). One pulp was sent to the prime laboratory, ALS Minerals, and the second sent to the second laboratory, Actlabs. A scatter plot of the two sets of analyses is shown in Figure 8-18 and shows a good correlation, with some scatter about the mean above 1% Cg. The average grade of the original analyses is 1.03% Cg versus the 1.01% for the replicate analyses, a difference of 0.02% Cg, and a relative difference of 1.9%.

Figure 8-18: Scatter Plot of Replicate Analyses of Hole AGC-03C

 

AGC sent 438 sample pulps from the whole drill program to Actlabs for replicate analyses. Samples were selected by taking every tenth sample. This represents 11.3% of the total of 3,856 unknown drill samples. One replicate sample was a marble blank which had originally given an unreliable analysis and so it was eliminated, leaving 437 samples to plot. A scatter plot of the original and replicate analyses is shown in Figure 8-19 and shows a close correlation between the two laboratories, with some scatter in the 1% to 2% range, and a possible slight high bias at Actlabs above 2.0% Cg. The average grade of the original analyses is 1.85% Cg and the average grade of the replicate analyses is 1.86%, with a relative difference of -0.8%.

 

A plot of the mean versus relative difference is shown in Figure 8-20. This plot shows that the majority of the samples (95.0%) have less than ±20% relative difference, i.e., the reproducibility is very good. Samples with a high relative difference along the x-axis are a data artifact close to or below the LLD: Actlabs has a LLD of 0.05% Cg, with eight samples below this which were converted to half of the LLD to plot, whereas ALS has a lower LLD of 0.01% with two samples below the LLD. The plot also shows a slight trend for the original ALS analyses to be higher and with more scatter than the replicates for samples below 1.5% Cg, whereas the Actlabs analyses are slightly higher than the originals for samples above 3% Cg. These slight systematic differences are interpreted to be inter-laboratory differences which may be due to differences such as analytical procedure, reagents used, and instrument calibration. The small differences are not considered to be significant and no adjustments to the original data are recommended. Overall, the data shows very good reproducibility.

No secondary laboratory lab checks have been completed by Westwater since acquiring the property.

 

8.4Sample Security

 

Core and samples are stored in a secure warehouse owned by Westwater in Kellyton, Alabama 35 miles to the east of the project that also has facilities for the field office, core logging, core cutting and core sampling. Core is stored in waxed card boxes on wooden pallets by hole number and wrapped with shrink wrap. Sonic core is stored in long plastic boxes. Pallets are moved by forklift truck.

 

Core is collected from the drill rig by Westwater geologist and brought to the warehouse by an Westwater truck, where it is logged, photographed and sampled. Diamond core is cut lengthwise by diamond saw in the warehouse, and one-half core is put in a plastic or cloth bag with a consecutive sample number tag, sample number in indelible marker, and sealed with a cable tie. The remaining half-core is returned to the core box and stored in the warehouse for reference. The sample number is marked in the core box by a sample number tag. Sonic core is cut lengthwise with a knife and sampled, numbered and stored in the same way as diamond core.

Samples are put in wooden crates on a pallet for shipping, each holding approximately 1,000 lbs (454 kg). The sample crates are covered but not sealed. They are transported by a UPS courier truck to the Actlabs laboratory in Elko, Nevada, or to the Activation Laboratories Ltd. (Actlabs) laboratory in Ancaster, Ontario, for sample preparation and analysis. The coarse sample rejects and pulps are back-shipped in the same crates by UPS to the warehouse in Sylacauga for storage.

 

8.5Conclusions

 

In the SLR QP’s opinion, the QA/QC program as designed and implemented by Westwater and its predecessor AGC meet current industry standard practice and the assay results within the database are suitable for use in a Mineral Resource estimate.

 

In the SLR QP’s opinion, the sample preparation, analysis, and security procedures at Coosa Graphite are adequate for use in the estimation of Mineral Resources.

9.0Data Verification

 

Data verification is the process of confirming that data has been generated with proper procedures, is transcribed accurately from its original source into the Project database, and is suitable for use in Mineral Resource estimation.

 

The SLR QP, visited the Project on April 23, 2022, accompanied by David Greenan (Consulting Geologist) of Westwater. During the site visit, the SLR QP was given an overview of the ongoing exploration drilling activities and a surface Project tour. The SLR QP also reviewed core handling, logging, sampling, and storage procedures.

 

As part of the data verification procedure, drill data was spot checked and audited by SLR for completeness and validity using standard database validation tests using tools provided within the Leapfrog Geo and Vulcan software programs and MS Excel to check for potential issues including:

 

Sample length and overlap issues

 

Maximum and minimum lengths and assay grades

 

Negative assay values

 

Drill hole deviations

 

Overlapping and/or duplicate entries

 

Gaps in assays/unsampled intervals

 

Assay outliers

 

AGC previously contracted Perry Remote Sensing, LLC (PRS) to purchase a precision digital elevation model (DEM) data for 56.5 mi2 (91 km2) of the Project area. The DEM data was used to make a triangulation surface in Vulcan which was used to register drill hole collars to this surface.

 

In addition, SLR reviewed the QA/QC methods and results, verified assay certificates against the database assay table, and reviewed drill core. No limitations were placed on SLR’s data verification process. The review of the QA/QC program and results is presented in Section 8, Sample Preparation, Analyses and Security. No independent samples were taken as part of this TRS.

 

No significant database issues were identified and the SLR QP is of the opinion that the database verification procedures for Coosa comply with industry standards and are adequate for the purposes of Mineral Resource estimation.

10.0Mineral Processing and Metallurgical Testing

 

Since acquiring the property in 2018, Westwater has conducted no metallurgical testing on the Project.

 

Bench-scale metallurgical test work programs on samples from the Coosa County deposit had been carried out at the SGS Minerals laboratories in Lakefield, Ontario, Canada in 2013 focusing on the grindability and flotation response of the various samples

 

In addition, a program of preliminary test work on flotation concentrates was carried out at a Canadian laboratory in 2015 to examine the response to thermal purification processing.

11.0Mineral Resource Estimates

 

11.1Summary

 

Mineral Resources have been classified in accordance with the definitions for Mineral Resources in S-K 1300. Mineral Resources estimated by SLR used all drill results available as of March 17, 2022. Graphitic carbon (Cg) material is present in two types of schist of an uncertain age ranging from Precambrian to Paleozoic, a quartz-graphite schist that generally has grades greater than 1% Cg and a quartz-biotite-graphite-schist that has grades generally less than 1% Cg and are often associated with disseminated pyrrhotite and minor pyrite along with the green vanadium-bearing muscovite and roscoelite mineralization.

 

The Mineral Resource estimate was completed using a conventional block modeling approach. The general workflow performed by SLR included the construction of a geological or stratigraphic model representing the Higgins Ferry Group Graphitic Schist sequence in Seequent’s Leapfrog Geo (Leapfrog Geo) from mapping, drill hole logging, and sampling data, which was used to define discrete domains and surfaces representing the upper contact of each unit. The geologic model was then used to constrain resource estimation. The resource estimate used regularized block models, the inverse distance squared (ID2) methodology, and length-weighted, 10 ft, uncapped composites to estimate the Cg and V in a three-search pass approach, using hard boundaries between subunits, ellipsoidal search ranges, and search ellipse orientation informed by geology. Average density values were assigned by lithological unit.

 

Estimates were validated using standard industry techniques including statistical comparisons with composite samples and parallel nearest neighbor (NN) estimates, swath plots, and visual reviews in cross-section and plan. A visual review comparing blocks to drill holes was completed after the block modeling work was performed to ensure general lithologic and analytical conformance and was peer reviewed prior to finalization.

 

Table 11-1 summarizes Cg Mineral Resources at a 1.98% Cg cut-off grade envisaging an open pit mining scenario. Indicated Mineral Resources total 26.0 Mst at an average grade of 2.89% Cg for a total of 754,000 st Cg. Inferred Mineral Resources total 97.0 Mst at an average grade of 3.08% Cg for a total of 3.0 Mst Cg.

To ensure that all Mineral Resource statements satisfy the “reasonable prospects for eventual economic extraction” (RPEEE) requirement, factors significant to technical feasibility and potential economic viability were considered. Mineral Resources were defined and constrained within an open pit shell that was prepared by SLR and based on a US$1,100/st graphite value.

 

The SLR QP is of the opinion that with consideration of the recommendations summarized in Sections 1 and 23 of this TRS, any issues relating to all relevant technical and economic factors likely to influence the prospect of economic extraction can be resolved with further work. There are no other known legal, social, or other factors that would affect the development of the Mineral Resources.

 

While the estimate of Mineral Resources is based on the QP's judgment that there are reasonable prospects for eventual economic extraction, no assurance can be given that Mineral Resources will eventually convert to Mineral Reserves.

 

11.2Resource Database

 

Westwater maintains a property wide drill hole database in a series of Excel spreadsheets. The Coosa resource database, dated March 17, 2022, includes drill hole collar locations (including dip and azimuth), assay, alteration, geochemical, and lithology data from 236 drill holes totalling 45,715 ft of drilling completed from 2012 through spring of 2022. The database contains information from diamond drilling (DD), sonic drilling, and trenches. Of the 236 drill holes completed, 205 drill holes totaling 39,434 ft were used in the resource estimation. The remaining 31 holes totaling 6,281 ft are exploration holes drilled in the HS-North area (13) or are isolated single holes (18) outside the Coosa block model boundaries and were excluded from the resource estimation. A summary of the drill hole database used for resource estimation is provided in Table 11-2.

Technical Report Summary - December 1, 202211-2 

 

 

 

Drilling holes completed by AGC generally were downhole surveyed with a single shot Reflex EZ Shot tool. Angled fence holes were surveyed at a midway depth of 250 ft (76.2 m) and again at the end of the hole (approximately 500 ft / 152.4 m) while the vertical grid holes were only surveyed at the end. Westwater did not conduct any downhole surveys due to the shallow depth of drilling (generally less than 100 ft). The SLR QP considers that the drill hole paths have been defined with sufficient accuracy for Mineral Resource estimation.

 

11.3Geological Interpretation

 

SLR geologists constructed geologic models for the Project in Leapfrog Geo software using topographic surfaces and drill hole lithology logs and cross sections supplied by Westwater. The four main mineralized geologic units modelled include QGS, INT, QMBGS, and QBGS. The SLR QP reviewed the sectional interpretations in section and on plan and is of the opinion that the cross sections reasonably honor the lithologic data.

 

In addition, the SLR QP also constructed geological models for the oxidized, transitional, and reduced (unweathered) zones. The geologic and weathering models at Coosa Graphite are illustrated in Figure 11-1 and Figure 11-2.

 

Westwater geologists completed 23 cross sections on generally 200 ft spacing oriented northwest-southeast across the Property. A relogging of previous drill core along with newly acquired core resulted in the identification of 20 thrust fault planes controlling lithologic boundaries. The relogging also updated the identification of amphibolite and pegmatite material showing interbedded lower grade mineralization within the QGS. The cross sections were digitized into Leapfrog Geo to aid in the resource estimation.

11.4Statistical Analysis

 

The geologic model was used to code the drill hole database and to identify samples within the mineralized zones. These samples were extracted from the database on a group-by-group basis, subjected to statistical analyses for their respective domains, and then analyzed by means of histograms and probability plots. A total of 9,198 graphitic carbon and 1,594 vanadium samples were contained within the mineralized wireframes. Statistics are summarized in Table 11-3 and the graphite grade histogram is illustrated in Figure 11-3.

Figure 11-3: Grade % Cg Histogram by Lithology

 

11.4.1Capping Levels

 

Where the assay distribution is skewed positively or approaches log-normal, erratic high grade assay values can have a disproportionate effect on the average grade of a deposit. One method of treating these outliers to reduce their influence on the average grade is to cut or cap them at a specific grade level.

 

The SLR QP employed a number of statistical analytical methods to determine an appropriate capping value, including preparation of frequency histograms, probability plots, decile analyses, and capping curves. Using these methodologies, SLR examined selected capping values for the mineralized zones for the Project and found that the assay grade distributions are reasonably uniform throughout the deposit. As a result, no capping was required for estimating a Mineral Resource.

 

11.5Compositing

 

Composites were created from the uncapped, raw assay values using the downhole compositing function in the Leapfrog Geo modelling software package. The composite lengths used during interpolation were chosen considering the predominant sampling length, the minimum mining width, style of mineralization, and continuity of grade. Sample lengths ranged from 1.0 ft to 70.0 ft within the wireframe models, with 97% of the samples taken at 5.0 ft intervals (Figure 11-4). Given this distribution, and considering the width of the mineralization, SLR chose to composite to 10.0 ft lengths.

11.6Variography

 

SLR generated downhole and directional variograms using the Cg composite values located within the QGS mineralized domain within the Main Grid area. The variograms were used to support search ellipsoid anisotropy, linear trends observed in the data, and Mineral Resource classification decisions. The downhole variograms suggest a relative low nugget effect of approximately 0.13%. Long range directional variograms were focused in the primary plane of mineralization, which generally strikes N30oE and is dipping 25o to the southeast.

 

Most of the variance occurs within the first 200 ft and is not represented by many sample pairs with the current drill hole spacing.

11.8Block Models

 

A regularized whole block approach was used whereby the block was assigned to the domain where its centroid was located. The block model was constructed using Leapfrog Edge version 2022.1 software oriented with an azimuth of 30o, dip of 0.0°, and a plunge of 0.0° to align with the overall strike of the mineralization with a parent cell size of 40 ft by 40 ft in the X (along strike) and Y (across strike) directions and 20 ft in the Z (vertical or bench height) direction, honoring modeled geological surfaces.

 

The model fully enclosed the modeled lithologic wireframes, with the model origin (lower-left corner at lowest elevation) at State Plane 1927 - Alabama East FIPS 0101 (US feet) coordinates 321,000 E, 876,000 N, and 200 fasl. A summary of the block model extents is provided in Table 11-5.

11.9Search Strategy and Grade Interpolation Parameters

 

The key element variables, C_graph and V_final, were interpolated using the ID2 methodology. Estimation of grades was controlled by mineralized geologic zones and target area boundaries. Hard boundaries were used to limit the use of composites between different mineralization domains for both graphite and vanadium interpolation.

 

The interpolation strategy involved setting up search parameters in three nested estimation runs. Most search ellipse dimensions were 100 ft x 100 ft x 25 ft for a 4:4:1 anisotropic ratio in the first pass, 250 ft x 250 ft x 25 ft for a 10:10:1 anisotropic ratio in the second, and 500 ft x 500 ft x 25 ft for a 20:20:1 anisotropic ratio for the third pass. Interpolation parameters for the Project Mineral Resource domains are listed in Table 11-6.

11.10Cut-off Grade and Whittle Parameters

 

Metal prices used for reserves are based on consensus, long term forecasts from banks, financial institutions, and other sources. For resources, metal prices used are slightly higher than those for reserves.

 

The Coosa Mineral Resource was constrained to a Whittle optimized pit shell to demonstrate RPEEE. The block model was exported from Leapfrog Edge into Vulcan by SLR engineers and then imported into Whittle. Input parameters for the Whittle pit optimization are provided in Table 11-7 and were based on available graphite project costs ($1,190/t at +80 mesh, 94% to 95% C) provided by Westwater based on the August 2022 Benchmark Mineral Intelligence Graphite Price Assessment. Applying these factors resulted in a COG of 1.98% Cg.

11.11Classification

 

Definitions for resource categories used in this TRS are those defined by SEC in S-K 1300. Mineral Resources are classified into Measured, Indicated, and Inferred categories.

 

A Mineral Resource is defined as a concentration or occurrence of material of economic interest in or on the Earth’s crust in such form, grade or quality, and quantity that there are reasonable prospects for economic extraction. A mineral resource is a reasonable estimate of mineralization, considering relevant factors such as cut-off grade, likely mining dimensions, location, or continuity, that with the assumed and justifiable technical and economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of all mineralization drilled or sampled.

Technical Report Summary - December 1, 202211-12 

 

 

 

Based on this definition of Mineral Resources, the Mineral Resources estimated in this TRS have been classified according to the definitions below based on geology, grade continuity, and drill hole spacing.

 

Measured Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of conclusive geological evidence and sampling. The level of geological certainty associated with a measured mineral resource is sufficient to allow a qualified person to apply modifying factors, as defined in this section, in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a measured mineral resource has a higher level of confidence than the level of confidence of either an indicated mineral resource or an inferred mineral resource, a measured mineral resource may be converted to a proven mineral reserve or to a probable mineral reserve.

 

Indicated Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of adequate geological evidence and sampling. The level of geological certainty associated with an indicated mineral resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an indicated mineral resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.

 

Inferred Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. The level of geological uncertainty associated with an inferred mineral resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an inferred mineral resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an inferred mineral resource may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

 

The SLR QP has considered the following factors that can affect the uncertainty associated with each classification of Mineral Resources: reliability of sampling data, confidence in interpretation and modelling of geological and estimation domains, and confidence in block grade estimates. The SLR QP offers the following conclusions related to each of these factors:

 

Reliability of sampling data:

 

oDrilling, sampling, sample preparation, and assay procedures follow industry standards.

 

oData verification and validation work confirm drill hole sample databases are reliable.

 

oNo significant biases were observed in the QA/QC analysis results.

 

Confidence in interpretation and modelling of geological and estimation domains:

 

oMineralization domains are interpreted manually in cross-sections and refined in longitudinal sections by an experienced resource geologist.

 

oThere is good agreement between the drill holes and mineralization wireframe shapes.

 

oThe mineralization wireframe shapes are well defined by sample data in areas classified as Indicated.

 

Confidence in block grade estimates:

 

oIndicated block grades correlate well, spatially and statistically, with composite data, both locally and globally.

Technical Report Summary - December 1, 202211-13 

 

 

 

 

Blocks were classified as Indicated or Inferred based on drill hole spacing, confidence in the geological interpretation, and apparent continuity of mineralization. All blocks supported by drill hole spacings up to 200 ft were classified as Indicated. All remaining blocks were assigned an Inferred category. SLR recommends drilling additional holes down dip and reviewing the classification criteria as more data become available.

 

11.12Block Model Validation

 

Blocks were validated using industry standard techniques including:

 

·Swath plots (Figure 11-6 to Figure 11-8).

·Visual inspection of assays and composites versus block grades (Figure 11-9).

·Statistical comparison (Table 11-8).

 

SLR found grade continuity to be reasonable and confirmed that the block grades were reasonably consistent with local drill hole composite grades.

 

11.12.1Swath Plots

 

The block model grades and nearest neighbor (NN) grades were compared by swath plots, examples of which are shown in Figure 11-6 to Figure 11-8. The swath plots show that there is good spatial correlation between the NN grades and block model grades, with both being slightly lower than the composite grade, indicating the block model results may be slightly conservative and underestimating the resource. SLR is of the opinion that this correlation could improve with additional deeper drilling across the property.

Technical Report Summary - December 1, 202221-1 

 

 

 

22.0Interpretation and Conclusions

 

SLR offers the following interpretations and conclusions on the Project:

 

·Graphite generally occurs as a result of metamorphism (regional or contact) of organic matter in sediments. Flake graphite is assumed to be derived from fine-grained sediments rich in organic matter.

 

·Graphite ores mined historically were almost entirely from the weathered zone (60 ft to 100 ft), partly because weathering is deep in this area and partly because the weathered rock could be gently crushed without blasting.

 

·The sample preparation, analysis, and security procedures at Coosa are adequate for use in the estimation of Mineral Resources.

 

·The QA/QC programs as designed and implemented by Westwater and its predecessor AGC meet current industry standard practice and the assay results within the database are suitable for use in a Mineral Resource estimate.

 

·No significant database issues were identified and the SLR QP is of the opinion that the database verification procedures for the Project comply with industry standards and are adequate for the purposes of Mineral Resource estimation.

 

·Relogging of previously drilled holes in conjunction with new drilling information allowed for more accurate interpretation and separation of lithologic units and improved understanding of geologic environment resulting in:

 

oImproved geologic model correlation to the 2014 Airborne Magnetic survey.

 

oIdentifying widespread and strong vanadium (roscoelite) mineralization in very close association with flake graphite mineralization.

 

·The Company has carried out an extensive geochemical sampling program to determine the presence and intensity of vanadium mineralization at the Project. Vanadium potential tonnage and grade are currently estimated to be 21.0 Mst to 67.0 Mst and 0.19% V2O5 to 0.13% V2O5, respectively. SLR notes that the potential quantity and grade are conceptual in nature, there has been insufficient exploration to define a Mineral Resource, and it is uncertain if further exploration will result in the target being delineated as a Mineral Resource.

Westwater Resources Announces Completion of Technical Report Summary for Its Coosa Graphite Deposit in Alabama

 

Centennial, CO – December 6, 2022: Westwater Resources, Inc. (“Westwater” or the “Company”) (NYSE American: WWR), an energy technology and battery-grade natural graphite development company, today announced it has completed the Initial Assessment (“Initial Assessment”) for the Company’s Coosa graphite deposit in Alabama (the “Coosa Deposit”) and filed its S-K 1300 Technical Report Summary (“TRS”) on Form 8-K with the Securities and Exchange Commission (“SEC”), disclosing mineral resources for the Coosa Deposit. The mineral resource estimate for the Coosa Deposit, based on 205 drill holes totaling 39,434 ft., was completed by SLR International Corporation (“SLR”) with an effective date of November 30, 2022.

 

Background:

 

·As a U.S. domestic and domiciled company, Westwater reports all mineral resources in accordance with Item 1300 of Regulation S-K (“S-K 1300”);

·S-K 1300 was adopted by the SEC to modernize mineral property disclosure requirements for mining registrants and to align U.S. disclosure requirements more closely for mineral properties with current industry and global regulatory standards; and

·The mineral resource estimates set forth in the TRS have not previously been reported under the S-K 1300 format.

 

The TRS was prepared as an Initial Assessment in accordance with S-K 1300 and was filed with the SEC on Form 8-K on December 6, 2022. The TRS was prepared on behalf of the Company by SLR, which qualifies as a Qualified Person as defined under Item 1302 of Regulation S-K.

 

Terence J. Cryan, Westwater’s Executive Chairman, stated: “We are pleased to achieve another milestone in advancing our graphite business with the completion of a technical study on the graphite resource at the Coosa Deposit. We believe the results of the technical study indicate that the Coosa Deposit is capable of supplying graphite concentrate to our Kellyton Graphite Processing Plant, and we continue to believe that the vertical integration of the Coosa Deposit and our Kellyton Graphite Processing Plant will create future shareholder value.”

 

About the Coosa Deposit

 

The Coosa Deposit is located at the southern end of the Appalachian Mountain range in the western part of Coosa County, Alabama. The deposit area is approximately 50 miles south-southeast of the city of Birmingham and 23 miles south-southwest of the town of Sylacauga. Westwater holds the mineral rights to approximately 41,965 acres under a long-term lease. The Coosa Deposit is located in the flake graphite belt of central Alabama, also known as the Alabama Graphite Belt, in parts of townships T. 21 N., T. 22 N., T. 23 N., and T. 24 N. and ranges R. 16 E., R. 17 E., R. 18 E., and R. 19 E.

 

 

 

 

The mineral resource estimate for the Coosa Deposit, based on 205 drill holes totaling 39,434 ft., was completed by SLR with an effective date of November 30, 2022. Based on a 1.98% graphitic carbon (Cg) cut-off grade indicated mineral resources total 26.0 million short tons (Mst) at an average grade of 2.89% Cg for a total of 754,000 short tons (st) Cg. Inferred mineral resources are estimated as 97.0 Mst at an average grade of 3.08% Cg for a total of 3.0 Mst Cg.

 

Cevat Er, Westwater’s Chief Technical Officer, commented: “The results of the Westwater drilling program completed earlier this year shows the potential for enhanced graphite carbon grades at the northern extension, HS-South, and the Fixico Mine areas of the Coosa Deposit. The Qualified Person recommends additional in-fill drilling that we expect, upon completion and evaluation, will convert a majority of inferred graphite resources in the oxidized zone to indicated resources, and could identify expansion opportunities. Westwater will be considering those and other recommendations as plans are developed to continue progressing the Coosa Deposit to production by the end of 2028.”

 

Mineral Resources

 

The TRS was prepared in accordance with the regulations set forth in S-K 1300 with the objective of disclosing the mineral resources at the Coosa Deposit. Based on the density of drilling, continuity of geology and mineralization, testing, and data verification, the mineral resource estimates meet the criteria for indicated or inferred mineral resources as summarized in the TRS.

 

Estimated mineral resources are summarized in the following table for indicated and inferred mineral resources, respectively, at a 1.98% Cg.  Mineral resources were estimated separately for each mineralized horizon.  Mineral resources are not mineral reserves and do not have demonstrated economic viability. However, considerations of reasonable prospects for economic extraction were applied to the mineral resource calculations within the TRS.
