The factors set forth under “Risk Factors” in Item 1A of this annual report on Form 10-K.

 

Many of these factors are beyond our ability to control or predict. Although we believe that the expectations reflected in our forward-looking statements are based on reasonable assumptions, such expectations may prove to be materially incorrect due to known and unknown risks and uncertainties. You should not unduly rely on any of our forward-looking statements. These statements speak only as of the date of this annual report on Form 10-K. Except as required by law, we are not obligated to publicly release any revisions to these forward-looking statements to reflect future events or developments. All subsequent written and oral forward-looking statements attributable to us and persons acting on our behalf are qualified in their entirety by the cautionary statements contained in this section and elsewhere in this annual report on Form 10-K.

 

CAUTIONARY STATEMENT REGARDING MINERALIZED MATERIAL

“Mineralized material” as used in this annual report on Form 10-K, although permissible under the United States Securities and Exchange Commission’s (“SEC”) Industry Guide 7, does not indicate “reserves” by SEC standards. We cannot be certain that any deposits at the Velardeña Properties, the El Quevar, Santa Maria or Rodeo properties or any deposits at our other exploration properties, will ever be confirmed or converted into SEC Industry Guide 7 compliant “reserves”. Investors are cautioned not to assume that all or any part of the disclosed mineralized material estimates will ever be confirmed or converted into reserves or that mineralized material can be economically or legally extracted. In addition, in this annual report on Form 10-K we also modify our estimates made in compliance with National Instrument 43-101 to conform to SEC Industry Guide 7 for reporting in the United States. Mineralized material is substantially equivalent to measured and indicated mineral resources (exclusive of reserves) as disclosed for reporting purposes in Canada, except that the SEC only permits issuers to report “mineralized material” in tonnage and average grade without reference to contained ounces.

ITEMS 1 AND 2:  BUSINESS AND PROPERTIES

 

Overview

 

We are a mining company holding a 100% interest in the Velardeña and Chicago precious metals mining properties and associated oxide and sulfide processing plants in the State of Durango, Mexico (the “Velardeña Properties”), a 100% interest in the El Quevar advanced exploration silver property in the province of Salta, Argentina, and a diversified portfolio of precious metals and other mineral exploration properties located primarily in or near historical precious metals producing regions of Mexico, Nevada and Argentina. The Velardeña Properties and the El Quevar advanced exploration property are our only material properties.

 

We remain focused on evaluating and searching for mining opportunities in North America with near term prospects of mining, and particularly for properties in Mexico within reasonable haulage distances of our Velardeña processing plants. We are also focused on evaluation activities at our El Quevar exploration property in Argentina and are continuing our exploration efforts on selected properties in our portfolio of approximately 12 exploration properties located primarily in Mexico.

 

Our management team is comprised of experienced mining professionals with extensive expertise in mineral exploration, mine construction and development, and mine operations. Our principal office is located in Golden, Colorado at 350 Indiana Street, Suite 650, Golden, CO 80401, and our registered office is the Corporation Trust Company, 1209 Orange Street, Wilmington, DE 19801. We also maintain an office at the Velardeña Properties in Mexico and exploration offices in Argentina and Mexico.

 

No Proven or Probable Mineral Reserves/Exploration Stage Company

 

We are considered an exploration stage company under the SEC criteria since we have not demonstrated the existence of proven or probable mineral reserves at any of our properties. In SEC Industry Guide 7, the SEC defines a “reserve” as that part of a mineral deposit which could be economically and legally extracted or produced at the time of the reserve determination. Proven or probable mineral reserves are those reserves for which (a) quantity is computed and (b) the sites for inspection, sampling, and measurement are spaced so closely that the geologic character is defined and size, shape and depth of mineral content can be established (proven) or the sites are farther apart or are otherwise less adequately spaced but high enough to assume continuity between observation points (probable). Mineral reserves cannot be considered proven or probable unless and until they are supported by a feasibility study, indicating that the mineral reserves have had the requisite geologic, technical and economic work performed and are economically and legally extractable.

 

Prior to suspending mining and processing at the Velardeña Properties in November 2015, we had revenues from the sale of silver, gold, lead and zinc products from the Velardeña and Chicago mines. We have not completed a feasibility study with regard to any of our properties to date. Any mineralized material discovered or extracted by us should not be considered proven or probable mineral reserves. As of December 31, 2019, none of our mineralized material met the definition of proven or probable mineral reserves. We expect to remain an exploration stage company for the foreseeable future. We will not exit the exploration stage until such time, if ever, that we demonstrate the existence of proven or probable mineral reserves that meet the guidelines under SEC Industry Guide 7.

 

Company History

 

We were incorporated in Delaware under the Delaware General Corporation Law in March 2009. From March 2009 through September 2011, we focused on the advancement of our El Quevar silver project in Argentina. On September 2, 2011, we completed a business combination transaction with ECU Silver Mining Inc. (“ECU”), resulting in our ownership of the Velardeña and Chicago silver, gold and base metals mines located in the Velardeña mining district in the State of Durango, Mexico as further described below under “—Velardeña Properties”.

 

Corporate Structure

 

Golden Minerals Company, headquartered in Golden, Colorado, is the operating entity through which we conduct our business.  We have a number of wholly-owned subsidiaries organized throughout the world, including in Mexico, Central America, South America, the Caribbean and Europe. We generally hold our exploration rights and properties through subsidiaries organized in the countries in which our rights and properties are located.

 

Our Competitive Strengths and Business Strategy

 

Our business strategy is to establish Golden Minerals as a mid-tier precious metals mining company focused in North America and Argentina. We also review strategic opportunities from time to time.

 

Velardeña Properties. Due to continuing net operating losses, we suspended mining and sulfide processing activities at the Velardeña Properties during the first half of November 2015 in order to conserve the future value of the asset. We have placed the mine and sulfide processing plant on care and maintenance to enable a re-start of either the mine or the mill when we are able to develop mining and processing plans that at then current prices for silver and gold indicate a sustainable positive operating margin (defined as revenues less costs of sales) or we are able to locate, acquire and develop alternative mineral sources that could be economically mined and transported to the Velardeña Properties for processing. The Velardeña Properties include a 300 tonne per day flotation sulfide mill, which includes three flotation circuits in which we can process sulfide material to make lead, zinc and pyrite concentrates. The properties also include a conventional 550 tonne per day cyanide leach oxide mill with a Merrill-Crowe precipitation circuit and flotation circuit located adjacent to our Chicago mine. In July 2015, we leased the oxide plant to Minera Hecla, S.A. de C.V. (“Hecla”), a Mexican corporation and wholly-owned subsidiary of Hecla Mining Company, to process its own material through the plant. The lease with Hecla has since been extended through December 31, 2020. We continue to evaluate and search for other oxide and sulfide feed sources, focusing on sources within haulage distance of our sulfide and oxide mills at the Velardeña Properties.

El Quevar Project. We continue to advance our El Quevar silver project in Salta Province, Argentina.  In September 2019, we released final results from the 2019 drilling program conducted at the El Quevar property, which began to outline a new shallow high-grade silver zone in the Vince area about 2 kilometers south west of the known Yaxtché deposit and suggested the potential to add to existing mineralized material estimates in the northeast sector of the Yaxtché deposit. We are continuing surface exploration in the district to identify further drill targets in the 57,000-hectare property area. Our property holdings contain two district-scale high sulfidation epithermal systems with potential to host additional precious metals deposits. We plan to continue to advance El Quevar as much as possible within the limits of our

current exploration budget and remain open to finding a partner to contribute to the funding of further exploration and development.

Exploration Focus. We are focused on evaluating and searching for mining opportunities in North America with high precious metal grades and low development costs with near term prospects of mining, and particularly properties within reasonable haulage distances of our Velardeña processing plants. We are also continuing our exploration efforts on selected properties in our portfolio of approximately [12] exploration properties located in Mexico, Nevada and Argentina.

 

Experienced Management Team. We are led by a team of mining professionals with approximately 60 years of combined experience in exploration, project development, and operations management, primarily in the Americas. Our executive officers have held senior positions at various large mining companies including, among others, Cyprus Amax Minerals Company, INCO Limited, Meridian Gold Company, Barrick Gold Exploration and Noranda Exploration.

 

Velardeña Properties

 

Location, Access and Facilities

 

The Velardeña Properties are comprised of two underground mines and two processing plants within the Velardeña mining district, which is located in the municipality of Cuencamé, in the northeast quadrant of the State of Durango, Mexico, approximately 65 kilometers southwest of the city of Torreón, Coahuila and approximately 140 kilometers northeast of the city of Durango, which is the capital of the State of Durango. The mines are reached by a seven kilometer road from the village of Velardeña which is reached by highway from Torreón and Durango. The Velardeña mining district is situated in a hot, semi-arid region.

 

Of the two underground mines comprising the Velardeña Properties, the Velardeña mine includes five different major vein systems including the Terneras, Roca Negra, San Mateo, Santa Juana and San Juanes systems. During 2015, we mined from the San Mateo, Terneras and Roca Negra vein systems as well as the Santa Juana vein system to augment grades as mining and processing rates ramped up.

 

We own a 300 tonne per day flotation sulfide mill situated near the town of Velardeña. The mill includes three flotation circuits in which we can process sulfide material to make lead, zinc and pyrite concentrates. We also own a conventional 550 tonne per day cyanide leach oxide mill with a Merrill-Crowe precipitation circuit and flotation circuit located adjacent to our Chicago mine. In July 2015, we leased the oxide plant to Hecla to process its own material through the plant. See “-Velardeña Properties Activities” below. The lease with Hecla has since been extended through December 31, 2020. We continue to evaluate and search for other oxide and sulfide feed sources, focusing on sources within haulage distance of our sulfide and oxide mills at the Velardeña Properties.

 

Prior to shutting down production at the Velardeña mines in 2015, we trucked material from the Velardeña mines to the sulfide plant. In January 2012 we completed a tailings pond expansion at the sulfide plant, which is fully permitted and has capacity to treat tailings for approximately four additional years at the average processing rate of 285 tonnes per day. At the oxide plant, Hecla is required to either leave unused at the end of the lease term an agreed amount of capacity in the tailings facility, or construct an additional expansion at its cost.

 

Power for all of the mines and plants is provided through substations connected to the national grid. Water is provided for all of the mines by wells located in the valley adjacent to the Velardeña Properties. We hold title to three wells located near the sulfide plant and hold certificates of registration to three wells located near the oxide plant. We are licensed to pump water from all six wells up to a permitted amount. We are currently pumping from the three wells associated with the oxide plant which is more than sufficient for Hecla’s processing operations.

 

The following map shows the location of the Velardeña Properties.

Property History

 

Exploration and mining in the Velardeña district extends back to at least the late 1500s or early 1600s, with large scale mining beginning in 1888 with the Velardeña Mining and Smelter Company. In 1902, the mining properties were acquired by ASARCO, who mined the property until 1926 when the mines were closed. For the next 35 years, the mines were operated from time to time by small companies and local miners. The property was nationalized in 1961, and in 1968 the sulfide processing plant was built by the Mexican government. In 1994, William Resources acquired the concessions comprising the Velardeña Properties. In 1997, ECU Gold (the predecessor to ECU Silver Mining Inc.) purchased from William Resources the subsidiaries that owned the concessions and the oxide processing plant. The sulfide processing plant was acquired in 2004.

 

Title and Ownership Rights

 

We hold the concessions comprising the Velardeña Properties through our wholly-owned Mexican subsidiary Minera William S.A. de C.V. At present, a total of 28 mineral concessions comprise the Velardeña Properties. The Velardeña Properties encompass approximately 316 hectares. The mineral concessions vary in size, and the concessions comprising each mineral property are contiguous within each of the Velardeña and Chicago properties. We are required to pay annual concession holding fees to the Mexican government to maintain our rights to the Velardeña mining concessions. In 2019, we made such payments totaling approximately $78,000 and expect to pay approximately $23,000 in 2020. We also own the surface rights to 144 hectares that contains the oxide plant, tailings area and access to the Chicago mine, along with surface lands that may be required for potential plant expansions. 

 

The Velardeña Properties are subject to the Mexican ejido system requiring us to contract with the local communities, or ejidos, surrounding our properties to obtain surface access rights needed in connection with our mining and exploration activities. We currently have contracts with two ejidos to secure surface rights for our Velardeña Properties with a total annual cost of approximately $35,000. We have a ten-year contract with the Velardeña ejido, which provides surface rights to certain roads and other infrastructure at the Velardeña Properties through 2021, and a 25-year contract with the Vista Hermosa ejido, which provides exploration access and access rights for roads and utilities for our Velardeña Properties until 2038.

We hold water concessions in wells that provide water for the Velardeña Properties. In Mexico, water concessions are granted by the National Commission of Water (“CNA”). Currently no new water concessions are being granted by the CNA; however, companies can acquire water concessions through purchase or lease from current concession holders. We hold title to three wells located near the sulfide plant and hold certificates of registration to three wells located near the

oxide plant. We are licensed to pump water from all six wells up to a permitted amount. We are required to make annual payments to the CNA to maintain our rights to these wells. In 2019 we made such payments totaling approximately $25,000 and expect to pay approximately the same amount in 2020. We are required to pay a fine to the CNA each year if we use too much water from a particular well or alternatively if we do not use a minimum amount of water from a particular well.

 

Geology and Mineralization

 

The Velardeña district is located at the easternmost limit of the Sierra Madre Occidental on the boundary between the Sierra Madre Oriental and the Mesa Central sub-provinces. Both of these terrains are underlain by Paleozoic and possibly Precambrian basement rocks.

 

The regional geology is characterized by a thick sequence of limestone and minor calcareous clastic sediments of Cretaceous age, intruded by Tertiary plutons of acidic to intermediate composition. During the Laramide Orogeny, the sediments were folded into symmetrical anticlines and synclines that were modified into a series of asymmetrical overturned folds by a later stage of compression.

 

A series of younger Tertiary stocks have intruded the older Cretaceous limestone over a distance of approximately 15 kilometers along a northeast to southwest trend. The various mineral deposits of the Velardeña mining district occur along the northeast southwest axis and are spatially associated with the intrusions and their related alteration.

 

An important northwest-southeast fracture system is associated with these intrusions and, in many cases, acts as the main focus of mineralization. The Velardeña Properties are underlain by a thick sequence of limestone that corresponds to rocks of the Aurora and Cuesta del Cura formations of Lower Cretaceous age.

 

Several types of Tertiary intrusive rocks are present in the Velardeña district. The largest of these rocks outcrops on the western flank of the Sierra San Lorenzo and underlies a portion of the Velardeña Properties. It is referred to as the Terneras pluton and forms a northeast oriented, slightly elongated body, considered to represent a diorite or monzodiorite that outcrops over a distance of about 2.5 kilometers. The adjacent limestone has been altered by contact metamorphism (exoskarn), and locally the intrusive has been metamorphosed (endoskarn).

 

The following is a description of the individual geological characteristics and mineralization found on each of the properties comprising the Velardeña and Chicago mines.

 

Velardeña Mine

 

The Santa Juana, Terneras, San Juanes and San Mateo vein deposits on the Velardeña property are hosted by Aurora Formation limestone, the Terneras intrusion and related skarn. The limestone is intruded by a series of multiphase diorite or monzodiorite stocks (Terneras intrusion) and dikes of Tertiary age that outcrop over a strike length of approximately 2.5 kilometers.

 

Two main vein systems are present on the Velardeña property. The first is a northwest striking system as found in the Santa Juana deposit, while the second is east-west trending and is present in the Santa Juana, Terneras, San Juanes and San Mateo deposits.

 

In the Santa Juana deposit, vein trends are steeply northeast dipping and northwest trending. The Terneras, San Juanes and San Mateo veins all strike east-west and dip steeply north. The most extensive of these is the Terneras vein, which was mined in the past over a strike length of 1,100 meters. All of these veins are observed to have extensive strike lengths and vertical continuity for hundreds of meters. The mineralogy of the east west system is somewhat different in that it contains less arsenic than the northwest Santa Juana veins.

 

Mineralization in the deposits located at the Velardeña mine belongs primarily to epithermal calcite quartz veins with associated lead, zinc, silver, gold and copper mineralization, typical of the polymetallic vein deposits of northern Mexico. The veins are usually thin, normally in the 0.2 meter to 0.5 meter range, but consistent along strike and down dip. Coxcomb and rhythmically banded textures are common.

 

2014 Technical Report

 

During the first quarter of 2015, the engineering firm of Tetra Tech, Inc. (“Tetra Tech”) completed an estimate of mineralized material at the Velardeña Properties, set forth in the following table:

 

				Silver		Gold

The Tetra Tech mineralized material estimate assumed a silver price of $25 per troy ounce, a gold price of $1,446 per troy ounce, and a cutoff grade of a net smelter return (“NSR”) of $100 per tonne.

 

The following table shows the commodity prices and metallurgical recoveries used to determine the cutoff grade.

 

					Sulfide		Oxide		Mixed
					Metallurgical		Metallurgical		Metallurgical
					Recovery		Recovery		Recovery
Metal		Metal Prices*			%		%		%
Silver		$	25 (oz)		89		68		50
Gold		$	1,446 (oz)		68		71		29
Lead		$	0.96 (lb)		83		—		25
Zinc		$	0.91 (lb)		83		—		37

 

---

* Amounts represent three-year average prices.

 

The cutoff grade of $100 NSR per tonne of mineralized material was determined by adding the estimated average costs of mining ($53 per tonne), processing ($27 per tonne) and general and administration ($20 per tonne). The average cost estimates are the same for both the Velardeña and Chicago mines. The NSR value of mineralized material was determined for each type of mineralized material (sulfide, mixed, and oxide) by multiplying a fractional factor that represents an estimated combination of metallurgical recovery, treatment charges, penalties and payment terms by the unit value of each metal and then multiplying by the expected amount of that metal in each block of inventoried material.

 

The following table shows the reduction in mineralized material reported in the Tetra Tech report that resulted from extraction and processing of mineralized material in 2015. As a result of the shutdown of mining and processing in November 2015, there are no results for 2016, 2017, 2018 or 2019.

Velardeña Properties Activities

 

In 2019 we received approximately $7.7 million in revenue from the lease of the oxide plant at Velardeña, comprised of approximately $5.3 million for direct plant charges and fixed fees and approximately $2.4 million for other

net reimbursable costs related to the services we provide under the lease. The lease is described in detail below. We also incurred approximately $1.7 million in expenses related to shut down costs and maintenance at our Velardeña Properties as a result of the suspension of mining and processing activities in November 2015. We retained a core group of employees, most assigned to operate the oxide plant that is leased to a third party and not affected by the shutdown. The retained employees also include an exploration group and an operations and administrative group to continue to advance our plans in Mexico, oversee corporate compliance activities, and to maintain and safeguard the longer-term value of the Velardeña assets.

 

In July 2015 we entered into a leasing agreement with Hecla to lease our Velardeña oxide plant for an initial term of 18 months beginning July 1, 2015. The lease agreement contained several lease extension options, and in the third quarter 2016, the lease was extended through June 2017. The 2016 extension included an agreement under which Hecla would construct, at its cost, certain tailings expansion facilities to accommodate Hecla's increased use of tailings capacity in excess of an agreed amount, while preserving flexibility for future tailings expansions. The tailings expansion has since been completed. The parties agreed that Hecla would either leave unused at the end of the lease term an agreed amount of capacity in the expanded tailings facility or construct an additional expansion at its cost. In connection with their agreement regarding tailings impoundment expansions, the parties agreed that Hecla had the right to extend the lease for an additional 18 months following June 30, 2017, or until December 31, 2018. On March 24, 2017, Hecla exercised its right to extend the lease until December 31, 2018.

 

On August 2, 2017, we granted Hecla an option to extend the oxide plant lease for an additional period of up to two years ending no later than December 31, 2020. On October 1, 2018, Hecla exercised its option to extend the oxide plant lease until December 31, 2020. On December 2, 2019 we entered into an additional amendment of the lease agreement with Hecla to reduce the per tonne fee payable by Hecla for the duration of the lease term, commencing on January 1, 2020, from $22 per tonne to $11 per tonne, however, the per tonne fee reverts back to $22 per tonne for any month in which either of the following conditions are met: (1) the Comex daily silver spot closing average price for such month is $20 per ounce or greater, and (2) the mill head grade average from the metallurgical balance for such month is 1,000 grams per ton equivalent silver head grade or greater. If either condition is met in any month, Hecla will pay the higher fee of $22.00 per tonne on all amounts processed in the oxide plant during such month. The reduced fee only applies to the tonnage-based payments under the lease agreement; the monthly lease payment of $125,000 per month is not affected by the amendment. The latest amendment also extended notice period for Hecla’s right to terminate the lease for any reason from 120 days’ notice to 150 days. Hecla has a one-time right of first refusal to continue to lease the plant following a termination notice through December 31, 2020 if we decide to use the oxide plant for our own purposes before December 31, 2020.

 

Hecla is responsible for ongoing operation and maintenance of the oxide plant. During the year ended December 31, 2019, Hecla processed approximately 158,000 tonnes of material through the oxide plant, resulting in total revenues to us of approximately $7.7 million, comprised of approximately $5.3 million for direct plant charges and fixed fees and approximately $2.4 million for other net reimbursable costs related to the services we provide under the lease. The $2.4 million of reimbursable costs are also reported as plant lease costs, resulting in net operating margin of approximately $5.3 million for the year ended December 31, 2019. However, because Hecla has the right to terminate the lease on 150 days’ notice, there is no assurance that these amounts will be received.

 

Mining and Processing

 

Aside from some minor test mining and crushing activities, there were no mining or processing activities, other than the Hecla lease, at our Velardeña Properties in 2018 or 2019 as a result of the shutdown of the mining and sulfide processing activities in November 2015. We expect to incur approximately $0.4 million in quarterly holding costs for as long as mining and processing activities remain suspended.

 

Environmental Matters and Permitting

 

We hold environmental licenses and environmental impact assessments that allow us to run our mines, plants and tailing facilities at our Velardeña Properties. We are required to update our environmental licenses and environmental impact assessments for expansion of or modification to any of the existing two processing plants. The construction of new infrastructure beyond the current plant facilities also would require additional permitting, which could include environmental impact assessments and land use permits.

 

Certain Laws Affecting Mining in Mexico

 

Mexico, officially the United Mexican States, is a federal constitutional republic in North America and bordered by the United States of America, Belize and Guatemala. Mexico is a federal democratic republic with 31 states and Mexico City. Each state has its own constitution and its citizens elect a governor, as well as representatives, to their respective state congresses. The President of Mexico is the head of the executive federal government. Executive power is exercised by the President, while legislative power is vested in the two chambers of the Congress of the Union. The three constitutional powers are the Judiciary, the Executive and the Legislature which are independent of each other.

 

Legislation Affecting Mining

 

The Mining Law, originally published in 1992 and amended in 1996, 2005, 2006 and 2014, is the primary legislation governing mining activities in Mexico. Other significant legislation applicable to mining in Mexico includes the regulations to the Mining Law, the Federal Law of Waters, the Federal Labor Law, the Federal Law of Fire Arms and Explosives, the General Law on Ecological Balance and Environmental Protection and regulations, the Federal Law of Duties and the Federal Law on Metrology and Standards.

 

The Concession System

 

Under Mexican law, mineral deposits are property of the Mexican republic, and a mining concession, granted by the executive branch of the federal government, is required for the exploration, exploitation and processing of mineral deposits. Mining concessions may only be granted to Mexican individuals domiciled in Mexico or companies incorporated and validly existing under the laws of Mexico. Mexican companies that have foreign shareholders must register with the National Registry of Foreign Investments and renew their registration on an annual basis. Mining concessions grant rights to explore and exploit mineral deposits but do not grant surface rights over the land where the concession is located. Mining concession holders are required to negotiate surface access with the land owner or holder (e.g., agrarian communities) or, should such negotiations prove unsuccessful, file an application with the corresponding administrative authority (Ministry of Economy or Ministry of Agrarian-Territorial-Urban Development) to obtain an easement, temporary occupancy, or expropriation of the land, as the case may be. An application for a concession must be filed with the Mining Agency or Mining Delegation located closest to the area to which the application relates.

 

Mining concessions have a term of 50 years from the date on which title is recorded in the Public Registry of Mining. Holders of mining concessions are required to comply with various obligations, including the payment of certain mining duties based on the number of hectares of the concession and the number of years the concession has been in effect. Failure to pay the mining duties can lead to cancellation of the relevant concession. Holders of mining concessions are also obliged to carry out and prove assessment works in accordance with the terms and conditions set forth in the Mining Law and its regulations. The regulations to the Mining Law establish minimum amounts that must be spent or invested on mining activities. A report must be filed in May of each year regarding the assessment works carried out during the preceding year. The mining authorities may impose a fine on the mining concession holder if one or more proof of assessment work reports is not timely filed.

 

Pursuant to amendments to the federal corporate income tax law, effective January 2014, additional duties are imposed on mining concession holders; see “—Taxes in Mexico”.

 

Environmental Legislation

 

Mining projects in Mexico are subject to Mexican federal, state and municipal environmental laws and regulations for the protection of the environment. The principal legislation applicable to mining projects in Mexico is the federal General Law of Ecological Balance and Environmental Protection, which is enforced by the Federal Bureau of Environmental Protection, commonly known as “PROFEPA”. PROFEPA is the federal entity in charge of carrying out environmental inspections and negotiating compliance agreements. Voluntary environmental audits, coordinated through PROFEPA, are encouraged under the federal General Law of Ecological Balance and Environmental Protection. PROFEPA monitors compliance with environmental legislation and enforces Mexican environmental laws, regulations and official standards. If warranted, PROFEPA may initiate administrative proceedings against companies that violate environmental laws, which proceedings may result in the temporary or permanent closure of non-complying facilities, the revocation of operating licenses and/or other sanctions or fines. According to the Federal Criminal Code, PROFEPA must inform the relevant governmental authorities of any environmental crimes that are committed by a mining company in Mexico.

 

Concession holders under the exploration stage may submit themselves to comply with the Mexican Official Norm: NOM-120-SEMARNAT-1997, which provides, among other things, that mining exploration activities to be carried out within certain areas must be conducted in accordance with the environmental standards set forth in NOM-120-SEMARNAT-1997; otherwise, concession holders are required to file a preventive report or an environmental impact study prior to the commencement of the exploration, exploitation and processing of mineral resources. An environmental impact study is required for exploitation and processing of mineral resources activities.

 

In 2014 Mexico developed an energy policy applicable to private investment companies whereby new mining concessions are now subject to prior approval from the Ministry of Energy. Current mining concessions forming the Velardeña Properties are not subject to or affected by this approval requirement, but any new mining concessions acquired will be subject to this additional approval.

 

Taxes in Mexico

 

Mexico has a federal corporate income tax rate of 30%, and there are no state taxes on corporate net income. In determining their corporate income tax, entities are allowed to subtract from gross income various deductions permitted by law, and they are allowed a ten-year carry-forward of net operating losses. Pursuant to amendments to the federal tax laws effective January 1, 2014, a 10% withholding tax is charged on dividends distributed to shareholders, regardless of the tax residence of the recipient, out of after tax profits. However, in the case of nonresident shareholders the limitations and tax rates provided in the treaties to avoid double taxation will prevail. A foreign resident company is subject to income tax if it has a permanent establishment in Mexico. In general, a permanent establishment is a place of business where the activities of an enterprise are totally or partially carried out and includes, among others, offices, branches and mining sites.

 

Under the 2014 amendments to the federal corporate income tax law, titleholders of mining concessions are required to pay an annual special duty of 7.5% of their mining related profits. Titleholders of mining concessions also are required to pay a 0.5% special mining duty, or royalty, on an annual basis, on revenues obtained from the sale of silver, gold and platinum. Both the 7.5% annual special duty and the 0.5% duty are due at the end of March each year. The special duty of 7.5% is generally applicable to earnings before income tax, depreciation, depletion, amortization, and interest. In calculating the special duty of 7.5%, there are no deductions related to depreciable costs from operational fixed assets, but exploration and prospecting depreciable costs are deductible when incurred. Both duties are tax deductible for income tax purposes.

 

Mexico has several taxes in addition to income tax that are relevant to most business operations, including (i) the Value Added Tax (“VAT”); (ii) import duties; (iii) various payroll taxes; and (iv) statutorily entitled employee profit sharing (“PTU”). In addition, annual mining concession fees are charged by the government.

 

VAT in Mexico is charged upon alienation of goods, performance of independent services, grant of temporary use or exploitation of goods, or import of goods or services that occur within Mexico’s borders, at a rate of 16%. There is no VAT in the case of export of goods or services or for the sale of gold, jewelry, and gold metalwork with a minimum gold content of 80%, excluding retail sale to the general public. The sale of mining concessions is subject to VAT as concessions are not considered to be land. VAT paid by a business enterprise on its purchases and expenses may usually be credited against its liability for VAT collected from customers on its own sales. This creditable VAT may also be directly refunded, but under new regulations beginning in January 2019, the creditable VAT can no longer offset other Mexican federal taxes.

 

Import duties apply for goods and services entering the country, unless specifically exempted due to a free trade agreement or registered under specific programs like IMMEX, under which we are currently registered. Payroll taxes are payable in most states including Durango and Coahuila, and social security, housing and pension contributions must be made to the federal government when paying salaries.

 

Employees of Mexico entities are statutorily entitled to a portion of the employer’s pre-tax profits, called PTU. The rate of profit sharing is currently 10% of the employer’s taxable income as defined by the Income Tax law. A taxpayer may reduce its income tax base by an amount equal to the PTU. Certain companies are exempt from paying PTU, which include companies in the extractive industry (principally the mining industry) during the period of exploration.

 

El Quevar

 

Location and Access

 

Our El Quevar silver project is located in the San Antonio de los Cobres municipality, Salta Province, in the altiplano region of northwestern Argentina, approximately 300 kilometers by road northwest of the city of Salta, the capital city of the province. The project is also accessible by a 300-kilometer dirt and gravel road from the city of Calama in northern Chile. The small village of Pocitos, located about 20 kilometers to the west of El Quevar, is the nearest settlement. We have established a camp approximately 10 kilometers west of the project to house project workers. A high-tension power line is located approximately 40 kilometers from the site, and a high-pressure gas line devoted to the mining industry and subsidized by the Salta government is located within four kilometers of the El Quevar camp.

 

The El Quevar project is located near Nevado Peak with altitudes at the concessions ranging from 3,800 to 6,130 meters above sea level. The climate of the area is high mountain desert, with some precipitation in summer (such as snow) and little snow in winter.

 

The following map shows the location of the El Quevar project.

 

Property History

 

Mining activity in and around the El Quevar project dates back at least 80 years. Between 1930 and 1950, there was lead and silver extraction of mineralized materials from small workings in the area, but we have no mining records from that period. The first organized exploration activities on the property occurred during the 1970s, although no data from that period remains. Over the last 30 years, several companies have carried out exploration activity in the area, including BHP Billiton, Industrias Peñoles, Mansfield Minerals and Hochschild Mining Group, consisting primarily of local sampling with some limited drilling programs.

 

Title and Ownership Rights

 

According to Argentine law, mineral resources are subject to regulation in the provinces where the resources are located. Each province has the authority to grant mining exploration permits and mining exploitation concession rights to applicants. The Federal Congress has enacted the National Mining Code and other substantive mining legislation, which is applicable throughout Argentina; however, each province has the authority to regulate the procedural aspects of the National Mining Code and to organize the enforcement authority within its own territory.

 

In the province of Salta, where the El Quevar project is located, all mining concessions are granted by a judge in the Salta Mining Court. The El Quevar project is comprised of exploitation concessions. Exploitation concessions are subject to a canon payment fee (maintenance fee) which is paid in advance twice a year (before June 30th and

December 31st of each calendar year). Each time a new mining concession is granted, concession holders are exempt from the canon payment fee for a period of three years from the concession grant date. However, this exemption does not apply to the grant of vacant exploitation concessions; only to the grant of new mining concessions.

 

The El Quevar project is currently comprised of 31 mining concessions that we hold directly. In total, the El Quevar project encompasses approximately 57,000 hectares. The area of most of our exploration activities at El Quevar is within the concessions that are owned by Silex Argentina S.A., our wholly-owned subsidiary.

 

We are required to pay a 1% net smelter return royalty on the value of all minerals extracted from the El Quevar II concession and a 1% net smelter return royalty on one-half of the minerals extracted from the Castor concession to the third party from whom we acquired these concessions. We can purchase one half of the royalty for $1 million in the first two years of production. The Yaxtché deposit is located primarily on the Castor concession. We may also be required to pay a 3% royalty to the Salta Province based on the net smelter value of minerals extracted from any of our concessions less costs of processing. To maintain all of the El Quevar concessions, we paid canon payment fees to the Argentine government of approximately $57,000 and $36,000 in 2018 and 2019, respectively. In 2020 we expect to pay approximately $30,000.

The surface rights at El Quevar are controlled by the Salta Province. There are no private properties within the concession area. To date, no issues involving surface rights have impacted the project. Although we have unrestricted access to our facilities, we have been granted easements to further protect our access rights.

 

Geology and Mineralization

 

The geology of the El Quevar project is characterized by silver-rich veins and disseminations in Tertiary volcanic rocks that are part of an eroded stratovolcano. Silver mineralization at El Quevar is hosted within a broad, generally east-west-trending structural zone and occurs as a series of north-dipping parallel sheeted vein zones, breccias and mineralized faults situated within an envelope of pervasively silicified brecciated volcanic rocks. There are at least three sub-parallel structures that extend for an aggregate length of approximately 6.5 kilometers. Several volcanic domes (small intrusive bodies) have been identified and mineralization is also found in breccias associated with these domes, especially where

they are intersected by the structures. The silver mineralization at the Yaxtché zone is of epithermal origin. The cross-cutting nature of the mineralization, the assemblage of sulfide and alteration minerals, and the presence of open spaces with euhedral minerals, all point to an origin at shallow to moderate depths (a few hundred meters below surface) from hydrothermal solutions.

 

During 2012, we released an estimate of mineralized material at our El Quevar project. This estimate assumed mining of oxide material from an open pit on the east end of the Yaxtché deposit and sulfide material from both the open pit and an underground mine on the western portion of the Yaxtché deposit. The estimate was based on results from 270 core drill holes.

 

In 2017, Wood Group USA, Inc. (formerly known as Amec Foster Wheeler E&C Services, Inc.) (“Wood”) undertook an analysis and re-modeling of data utilized in a 2012 mineralized material estimate based on results from 270 core drill holes and assumed mining material from the Yaxtché deposit. The Wood estimate, which we announced in February 2018, used updated geologic controls and a modeling method that optimized silver grade assuming mining would occur solely underground.

 

In September 2018, we completed a PEA prepared pursuant to NI 43-101 that used the February 2018 revised estimate of mineralized material for the Yaxtché deposit as a basis. The PEA contemplates a six-year underground mining operation using pre-existing and new underground development at a mine production rate of 1,200 tonnes per day using a post-pillar cut-and-fill mining method that will deliver 2.45 million tonnes of diluted sulfide material at an average grade of 409 g/t silver. As contemplated in the PEA, the mined material would be processed using a conventional single product flotation mill that would produce a silver-rich bulk concentrate suitable for sale.

 

For further detail regarding mineralized material, see “CAUTIONARY STATEMENT REGARDING MINERALIZED MATERIAL”.

 

Exploration and Advancement of El Quevar

 

The Yaxtché deposit is the primary target currently identified at the El Quevar project. In the first quarter 2019, we initiated a 3,000 meter, approximately $0.6 million, drilling program to further define the potential for additional mineralized material in the Yaxtché deposit and surrounding area and completed that drill program in the second quarter 2019. In September 2019, we released final results from the drilling program.  See “Management’s Discussion and Analysis of Financial Condition and Results of Operations – 2019 Highlights – El Quevar” for a discussion of the 2019 drill program.

 

We spent approximately $1.3 million and $2.0 million at our El Quevar project in 2018 and 2019, respectively. The increase in 2019 was primarily related to a drilling program conducted during the year. From the inception of our exploration activities in 2004 through December 31, 2019 we have spent approximately $82.0 million on exploration and related activities at El Quevar, including amounts spent by our predecessor, Apex Silver Mines Limited. In 2020, we expect to spend approximately $0.8 million at our El Quevar project to fund ongoing exploration and evaluation activities, care and maintenance and property holding costs.

 

We are continuing surface exploration in the district to identify further drill targets in the 57,000-hectare property area. Our property holdings contain two district-scale high sulfidation epithermal systems with potential to host additional precious metals deposits. We plan to continue to advance El Quevar as much as possible within the limits of our current exploration budget and remain open to finding a partner to contribute to the funding of further exploration and development.

Exploration Properties

 

In addition to Velardeña and El Quevar, we currently control a portfolio of approximately 12 exploration properties located primarily in certain traditional precious metals producing regions of Mexico, Nevada and Argentina. We do not consider any of our exploration properties to be individually material, including those noted below.

 

In 2020 we plan to focus our exploration efforts primarily on evaluating and searching for mining opportunities in North America with near term prospects of mining. We are also focused on continuing our exploration efforts on selected properties in our portfolio of approximately 12 exploration properties located in Mexico, Nevada, and Argentina. During 2020 we expect our expenditures for the exploration program to total approximately $3.0 million, with approximately $0.3 million in property holding costs in Mexico, $0.1 million in holding costs in Nevada and approximately $0.5 million in administrative and general reconnaissance costs in Mexico.

 

Sale of Mogotes and Pistachon Properties

 

On December 18, 2019, we sold the non-strategic Mogotes and Pistachon properties in Mexico to a subsidiary of Industrias Peñoles for $3.0 million. The Mogotes and Pistachon properties are comprised of a total of four mining concessions located near our Velardeña Properties in Durango State, Mexico and adjacent to mineral concessions controlled by subsidiaries of Industrias Peñoles. None of the claims in the properties contained any identified mineralized material estimates.

 

Our Rodeo claims are comprised of approximately 1,900-hectares located 80 kilometers west of the Velardeña Properties in Durango, Mexico. Previous exploration by other companies has identified a gold-bearing epithermal system exposed at the surface. During 2016, we completed a 2,080-meter core drilling program at the Rodeo property at a cost of approximately $0.4 million. The results from the program show a gold and silver bearing epithermal vein and breccia system with encouraging gold and silver values over an approximate 50 to 70-meter true width. The system is exposed at the top of a northwesterly striking ridge and dips steeply to the northeast over about one kilometer of strike length.

During January 2017, Tetra Tech completed an estimate of mineralized material at the Rodeo deposit, prepared pursuant to NI 43-101, based on two different operating scenarios. The first operating scenario reflects a smaller amount of higher-grade material and estimated mineralized material of 0.4 million tonnes containing 3.3 gpt gold and 11 gpt silver. This scenario provides a potentially shorter time to processing with lower capital costs since we already own the mill, located within trucking distance of the Rodeo property. The second operating scenario reflects a larger amount of lower grade material and estimated mineralized material of 3.6 million tonnes containing 0.8 gpt gold and 12 gpt silver. The second mineralized material estimate envisions a standalone heap leach operation, depending on leachability of the material and development and operating costs. We believe the Rodeo material, as currently identified, could provide additional mined material for our Velardeña oxide mill following the completion of the Hecla lease, which is currently set to expire on December 31, 2020.

In initial test work conducted in 2017, we received confirmation of good gold and silver metallurgical recoveries for milled material in initial test work. Bottle roll cyanide leach testing of the high-grade samples resulted in gold extractions of 80 to 86 percent. Silver extractions ranged from 72 to 76 percent for all tests. Test work also indicates that the material is not suitable for gold and silver recovery by heap leaching. 

 

We plan to initiate a small drilling program at Rodeo to provide greater resource definition for a mine plan and to provide samples for additional metallurgical testing. We have begun the process of obtaining the required mining and environmental permits for an open pit mining operation, a process that could take up to one year. Complementary to the permitting process, we have initiated an internal study to support the potential economic results of the planned operation.

 

Yoquivo

 

The Yoquivo property was acquired in 2017 and with the recent additional acquisition of a claim internal to the exterior boundary the project consists of 1,975 hectares in 7 claims that cover an epithermal vein district hosted in Tertiary andesitic volcanic rocks that is exposed in an erosional window through Oligocene rhyolite on the eastern margin of the Sierra Madre Occidental of northern Mexico. The property is 200 km SW of Chihuahua city in the state of Chihuahua, Mexico. Surface rock sampling done in 2018 demonstrated gold and silver values of potential economic interest in several of the veins in the district. We have an option to purchase the six concessions that comprise the Yoquivo property for payments totaling $0.75 million over four years subject to a 2% to 3% NSR royalty on production, capped at $2.8 million.

 

In October 2018 we announced high-grade silver-gold assays from the Yoquivo project. Multiple silver-gold bearing epithermal veins were mapped and sampled, with the two most important veins being the San Francisco and Pertenencia veins. A new vein, the La Nina vein, was discovered in the northwest of the property where it splits off from the main San Francisco vein. Two other veins, the Esperanza and El Dolar veins have been identified and sampled. Based on sampling and mapping we have identified the most attractive targets on the property and have permits in hand to initiate the drill program. Subject to the availability of capital, we intend to begin a drill program in the second or third quarter of 2020 to test the most promising portions of the veins.

 

On October 16, 2019, we entered into an option agreement for the sale of our right to acquire a 100% interest in the Santa Maria and Las Marias exploration properties to Magellan Gold Corporation (“Magellan”). The agreement provides for a period of up to 150 days during which Magellan will complete its due diligence review and secure financing for the project. Prior to the end of such period, Magellan will have the right to exercise its option to acquire our interests in the project. Under the terms of the agreement, if Magellan exercises its option, it will make a cash payment of $1.0 million to us upon closing. We will retain a 6.5% NSR royalty from all production at Santa Maria until a total of $3.0 million has been paid to us under the royalty agreement. Thereafter, we will retain a 3.0% NSR royalty for the balance of the mine’s life. If Magellan fails to achieve commercial production from the project within one year following closing, we will not be obligated to convey our interests in the project to Magellan and we will retain our interest in the project with no obligation to return any payments to Magellan.

 

In August 2014, we entered into an option agreement giving us the right to acquire for $1.2 million the Santa Maria mine, a privately held property comprised of a single mining claim of 18 hectares west of Hidalgo de Parral, Chihuahua State, Mexico. Since 2015, we have completed test mining and processing of approximately 7,100 dry tonnes from the Santa Maria mine, with average grades of 338 gpt silver and 0.8 gpt gold. In March 2017, an updated PEA was completed on our behalf by the engineering firm Tetra Tech, prepared pursuant to NI 43-101, and presented a base case assessment of developing Santa Maria’s mineral deposit. In September 2018, Tetra Tech completed an updated PEA for the Santa Maria project that incorporates data accumulated since March 2017 as well as information from a 22-hole, 4,800-meter drilling program begun in August 2017 and completed in April 2018. In total, we have drilled 9,900 meters in 59 holes since acquiring the property. Since 2015, we have completed test mining and processing of 7,100 dry tonnes from the Santa Maria mine west of Hidalgo de Parral, Chihuahua, with average grades 338 g/t Ag and 0.8 g/t gold (“Au”).

 

We have the right to acquire 100% of the Santa Maria property under two separate option agreements representing the total concessions that comprise the property for additional payments of $0.6 million, payable through August 2021. The first option agreement covers concessions we acquired in August 2014 and requires an additional minimum payment of approximately $0.2 million in 2020. In addition, until the total due under the first option agreement has been paid, the property owners have the right to 50% of any net profits from mining activities from the concessions related to the option, after reimbursement of all costs incurred by us since April 2015, to the extent that such net profit payments exceed the minimum payments. The second option agreement covers concessions acquired in August 2017 and requires an additional approximately $0.4 million be paid by making additional payments of $0.1 million in 2020 and $0.3 million in 2021. Under

the terms of the agreement discussed above, Magellan will assume responsibility for making the additional payments if it elects to exercise the option.

 

Sand Canyon

 

During the second quarter 2019 we entered into an earn-in agreement with Golden Gryphon Explorations for the Sand Canyon project located in northwestern Nevada, where surface work has identified a large system of epithermal veins with potential for gold and silver deposits. We hold an option to earn a 60% interest in the Sand Canyon project by spending $2.5 million in exploration expenses over four years, with guaranteed minimum expenditures of $0.5 million in year one. To continue to earn interest in the project, we must spend at least $0.75 million in each of years two and three and $0.5 million in year four, and drill at least 5,000 feet of core or 10,000 feet of reverse circulation or a combination of the two, by the end of the second year. We paid $25,000 cash and $50,000 in reimbursed exploration expenditures to acquire the option and will make staged payments of a total additional $135,000 ($35,000 in 2020, $50,000 in 2021 and $50,000 in 2022) over the next three anniversaries of the agreement.

 

We have completed surface exploration activities on the project including mapping and geochemical sampling to identify drill targets. Based on this work we have obtained the necessary drill permits and have begun a drilling program, with initial results expected in the second quarter of 2020.

Metals Market Overview

 

We are an emerging precious metals exploration company with silver and gold mining properties in Mexico and a large advanced exploration silver project in Argentina. Descriptions of the markets for these metals are provided below.

 

Silver Market

 

Silver has traditionally served as a medium of exchange, much like gold. Silver’s strength, malleability, ductility, thermal and electrical conductivity, sensitivity to light and ability to endure extreme changes in temperature combine to make it a widely used industrial metal. While silver continues to be used as a form of investment and a financial asset, the principal uses of silver are industrial, primarily in electrical and electronic components, photography, jewelry, silverware, batteries, computer chips, electrical contacts, and high technology printing. Silver’s anti-bacterial properties also make it valuable for use in medicine and in water purification. Additionally, the use of silver in the photovoltaic and solar panel industries is growing rapidly, and new uses of silver are being developed in connection with the use of superconductive wire and radio frequency identification devices.

 

Most silver product is obtained from mining in which silver is not the principal or primary product. The Silver Institute, an international silver industry association, noted that for 2018 only around 26% of output came from so-called primary silver mines, where silver is the main source of revenue.

 

The following table sets forth for the periods indicated on the London Fix high and low silver fixes in U.S. dollars per troy ounce. On February 25, 2020, the closing price of silver was $18.33 per troy ounce.  

		Silver
Year		High			Low
2012		$	37.23		$	26.67
2013		$	32.23		$	18.61
2014		$	22.05		$	15.28
2015		$	18.23		$	13.71
2016		$	20.71		$	13.58
2017		$	18.56		$	15.22
2018		$	17.52		$	14.13
2019		$	19.31		$	14.38
2020*		$	18.78		$	17.47

 

*Through February 25, 2020.

 

Gold Market

 

Gold has two main categories of use: fabrication and investment. Fabricated gold has a variety of end uses, including jewelry, electronics, dentistry, industrial and decorative uses, medals, medallions and official coins. Gold investors buy gold bullion, official coins and jewelry. The supply of gold consists of a combination of production from mining and the draw-down of existing stocks of gold held by governments, financial institutions, industrial organizations and private individuals.

 

The following table sets forth for the periods indicated on the London Fix PM high and low gold fixes in U.S. dollars per troy ounce. On February 25, 2020, the closing price of gold was $1,650 per troy ounce.

 

		Gold
Year		High			Low
2012		$	1,792		$	1,540
2013		$	1,694		$	1,192
2014		$	1,385		$	1,142
2015		$	1,296		$	1,049
2016		$	1,366		$	1,077
2017		$	1,346		$	1,151
2018		$	1,355		$	1,178
2019		$	1,546		$	1,270
2020*		$	1,672		$	1,527

*  Through February 25, 2020.

 

Employees

 

We currently have 170 employees, including seven in Golden, approximately 152 in Mexico (including approximately 76 assigned to the oxide plant which is leased to a third party and 19 involved in exploration activities), and 11 in Argentina, primarily in connection with the El Quevar project.

 

Competition

 

There is aggressive competition within the mining industry for the acquisition of a limited number of mineral resource opportunities, and many of the mining companies with which we compete have greater financial and technical resources than we do. Accordingly, these competitors may be able to spend greater amounts on acquisitions of mineral properties of merit, as well as on exploration and advancement of their mineral properties. We also compete with other mining companies for the acquisition and retention of skilled mining engineers, mine and processing plant operators and mechanics, geologists, geophysicists and other experienced technical personnel. Our competitive position depends upon our ability to successfully and economically advance new and existing silver and gold properties. Failure to achieve and maintain a competitive position could adversely impact our ability to obtain the financing necessary for us to advance our mineral properties.

ITEM 1A:RISK FACTORS 

Investors in Golden Minerals should consider carefully, in addition to the other information contained in, or incorporated by reference into, this annual report on Form 10-K, the following risk factors:

We have historically incurred operating losses and operating cash flow deficits and we expect to incur operating losses and operating cash flow deficits through 2020; our potential profitability in the foreseeable future would depend on our ability to identify, acquire and mine properties to generate sufficient revenues to fund our continuing activities.

   We have a history of operating losses and we expect that we will continue to incur operating losses unless and until such time as our Velardeña Properties, our El Quevar project, or another of our exploration properties, generates sufficient revenue to fund our continuing business activities. Although we have leased the oxide plant at the Velardeña Properties to a subsidiary of Hecla Mining Company, the cash that we expect will be generated from that lease will not be sufficient to fund all of our continuing business activities as currently conducted. In addition, the oxide plant lease may terminate sooner or produce less revenue than we anticipate. There is no assurance that we will develop additional sources of revenue.

   In addition, the potential profitability of mining and processing at any of our properties would be based on a number of assumptions. For example, profitability would depend on metal prices, costs of materials and supplies, costs at the mines and processing plants and the amounts and timing of expenditures, including expenditures to maintain our Velardeña Properties, our El Quevar project and to continue exploration at other exploration properties, and potential strategic acquisitions or other transactions, in addition to other factors, many of which are and will be beyond our control. We cannot be certain we will be able to generate sufficient revenue from any source to achieve profitability and eliminate operating cash flow deficits, or to cease to require additional funding.

We will require additional external financing to fund our continuing business activities in the future. 

As of December 31, 2019, we had approximately $4.6 million in cash and cash equivalents. With anticipated costs during 2020, including exploration expenditures, care and maintenance costs at the Velardeña Properties, exploration and evaluation expenditures and property holding costs at the El Quevar project, and general and administrative expenses, offset by anticipated net operating margin from the lease of the oxide plant of $3.3 million, we expect our current cash and cash equivalent balance will be approximately zero by the end of 2020, unless we are successful in raising additional capital or selling certain exploration assets. Even with these anticipated revenues throughout 2020, our cash balance in 2020 will not be sufficient to provide adequate cash reserves in the event of an unexpected termination of the Hecla lease, variations from anticipated care and maintenance costs at the Velardeña Properties and costs for continued exploration, project assessment and development at our other exploration properties, requiring us to seek additional funding from equity or debt or from monetization of non-core assets.

   We do not have a credit, off-take or other commercial financing arrangement in place that would finance our general and administrative costs and other working capital needs to fund our continuing business activities in the future, and we believe that securing credit for these purposes may be difficult given our limited history and the continuing volatility in global credit and commodity markets. In addition, commercial financing arrangements may not be available on favorable terms or on terms that would not further restrict our flexibility and ongoing ability to meet our cash requirements over a reasonable period of time. Access to public financing has been negatively impacted by the volatility in the credit markets and metals prices, which may affect our ability to obtain equity or debt financing in the future and, if obtained, to do so on favorable terms. We also may not be able to obtain funding by monetizing additional non-core exploration or other assets at an acceptable price. We cannot assure you that we will be able to obtain financing to fund our general and administrative costs and other working capital needs to fund our continuing business activities in the future on favorable terms or at all.

Although we may be able to access public equity markets, including through issuances under our At-the-Market program we entered into in December 2016 (the “ATM Program”) or the committed equity program with Lincoln Park Capital that we entered into in May 2018 (the “LPC Program”), significant issuances under those programs may be heavily dilutive to existing shareholders. 

Hecla may terminate the oxide plant lease.

   In July 2015 we entered into a leasing agreement with a wholly owned subsidiary of Hecla Mining Company to lease our Velardeña oxide plant for an initial term of 18 months beginning July 1, 2015. The lease agreement contained several lease extension options, which Hecla exercised, extending the current lease term through December 31, 2020. Hecla is responsible for ongoing operation and maintenance of the oxide plant and during the year ended December 31, 2019, Hecla's mining and processing activities resulted in a net margin of $5.3 million for us. The lease may terminate sooner than the end of 2020 if Hecla experiences mining problems or delays at its nearby mine, if there are disputes between Hecla and us, or for other reasons. Hecla has the right to terminate the lease on 150 days’ notice. Moreover, the lease payment from Hecla is based, in part, on the amount of ore processed at the plant, and we have no control over their production.

One of our stockholders owns a significant percentage of our common stock and could block decisions or transactions that could be beneficial to other stockholders.

   One of our stockholders, The Sentient Group, through the Sentient executive funds (“Sentient”), owns approximately 38% of our outstanding common stock. With this level of ownership, Sentient could exert significant control over us, including over the election of directors, changes in the size or the composition of the board of directors, and mergers and other business combinations involving us. Through greater control of the board of directors and increased voting power, including the potential to prevent a quorum at stockholders meetings, Sentient could control certain decisions, including decisions regarding qualification and appointment of officers, operations of the business including acquisition or disposition of our assets or purchases and sales of mining or exploration properties, dividend policy, and access to capital (including borrowing from third-party lenders and the issuance of equity or debt securities). Sentient’s large share ownership will also make it difficult, if not impossible, for us to enter into a change of control transaction that may otherwise be beneficial for our other shareholders.

If we commence mining in Mexico, we will likely enter into a collective bargaining agreement with a union that, together with labor and employment regulations, could adversely affect our mining activities and financial condition.

As is the case at our Velardeña Properties, mine employees in Mexico are typically represented by a union, and our relationship with our employees is, and we expect in the future will be, governed by collective bargaining agreements. Any collective bargaining agreement that we enter into with a union is likely to restrict our mining flexibility in and impose

additional costs on our mining activities. In addition, relations between us and our employees in Mexico may be affected by changes in regulations or labor union requirements regarding labor relations that may be introduced by the Mexican authorities or by labor unions. Changes in legislation or in the relationship between us and our employees may have a material adverse effect on our mining activities and financial condition.

We may not mine the Velardeña Properties again.

 

In mid-November 2015, we shut down the mines and sulfide processing plant at our Velardeña Properties and placed them on care and maintenance. Commencing mining again is subject to numerous risks and uncertainties, including:

Based on these risks and uncertainties, there can be no assurance that we will restart mining activities at the Velardeña Properties.

Our ability to successfully conduct mining and processing activities resulting in long-term cash flow and profitability will be affected by changes in prices of silver, gold and other metals.

Our ability to successfully conduct mining and processing activities in Mexico, Argentina or other countries, to establish reserves and advance our exploration properties, and to become profitable in the future, as well as our long-term viability, depend, in large part, on the market prices of silver, gold, zinc, copper and other metals. The market prices for these metals are volatile and are affected by numerous factors beyond our control, including:
