SCIENTIFIC AND TECHNICAL INFORMATION

Unless otherwise indicated, scientific and technical information in this Annual Information Form relating to each of our: Marigold mine has been reviewed and approved by Greg Gibson, P.E. and SME Registered Member, our General Manager at the Marigold mine, and James N. Carver, SME Registered Member, our Exploration Manager at the Marigold mine, each of whom is a qualified person under National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”); Seabee Gold Operation has been reviewed and approved by Cameron Chapman, P.Eng., our General Manager at the Seabee Gold Operation and Jeffrey Kulas, P. Geo., our Manager Geology, Mining Operations at the Seabee Gold Operation, each of whom is a qualified person under NI 43-101; Puna Operations has been reviewed and approved by Robert Gill, P.Eng., our General Manager at Puna Operations, and F. Carl Edmunds, P. Geo., our Vice President, Exploration, each of whom is a qualified person under NI 43-101; and other mineral properties has been reviewed and approved by Samuel Mah, P.Eng., our Director, Mine Planning, and F. Carl Edmunds, P.Geo., our Vice President, Exploration, each of whom is a qualified person under NI 43-101. See “Interests of Experts”.

A “qualified person” for the purposes of NI 43-101 means an individual who is an engineer or geoscientist, holding the required accreditation, with at least five years of experience in mineral exploration, mine development or operation or mineral project assessment, or any combination of these, has experience relevant to the subject matter of the mineral project, and is a member in good standing of a professional association.

CAUTIONARY NOTICE REGARDING MINERAL RESERVES AND MINERAL RESOURCES ESTIMATES

The disclosure included in this Annual Information Form uses Mineral Reserves and Mineral Resources classification terms that comply with reporting standards in Canada and the Mineral Reserves and Mineral Resources estimates are made in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards on Mineral Reserves and Mineral Resources (the “CIM Standards”) adopted by the CIM Council on May 10, 2014, and NI 43-101. NI 43-101 is a rule developed by the Canadian Securities Administrators (“CSA”) that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. The following definitions are reproduced from the CIM Standards:

A Mineral Resource is a concentration or occurrence of solid 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 eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. Mineral Resources are sub-divided, in order of increasing geological confidence, into inferred, indicated and measured categories.

- 4 -

An 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. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.

An Indicated Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve. “Modifying Factors” are considerations used to convert Mineral Resources to Mineral Reserves. These include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.

A Measured Mineral Resource is that part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.

A Mineral Reserve is the economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at Pre-Feasibility or Feasibility (as such terms are defined in the CIM Standards) level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified. The reference point at which Mineral Reserves are defined, usually the point where the ore is delivered to the processing plant, must be stated. It is important that, in all situations where the reference point is different, such as for a saleable product, a clarifying statement is included to ensure that the reader is fully informed as to what is being reported. Mineral Reserves are sub-divided in order of increasing confidence into Probable Mineral Reserves and Proven Mineral Reserves. The public disclosure of a Mineral Reserve must be demonstrated by a Pre-Feasibility Study or Feasibility Study.

A Probable Mineral Reserve is the economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource. The confidence in the Modifying Factors applying to a Probable Mineral Reserve is lower than that applying to a Proven Mineral Reserve.

A Proven Mineral Reserve is the economically mineable part of a Measured Mineral Resource. A Proven Mineral Reserve implies a high degree of confidence in the Modifying Factors.

Unless otherwise indicated, all Mineral Reserves and Mineral Resources estimates included in this Annual Information Form have been prepared in accordance with NI 43-101. These standards differ significantly from the requirements of the U.S. Securities and Exchange Commission (“SEC”) set out in SEC Industry Guide 7. Consequently, Mineral Reserves and Mineral Resources information included in this Annual Information Form is not comparable to similar information that would generally be disclosed by domestic U.S. reporting companies subject to the reporting and disclosure requirements of the SEC.

- 5 -

In particular, SEC Industry Guide 7 applies different standards in order to classify mineralization as a reserve. As a result, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” used in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC standards, mineralization may not be classified as a “reserve” unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Among other things, all necessary permits would be required to be in hand or issuance imminent in order to classify mineralized material as reserves under the SEC standards. Accordingly, Mineral Reserves estimates included in this Annual Information Form may not qualify as “reserves” under SEC standards.

In addition, this Annual Information Form uses the terms “Mineral Resources,” “Measured Mineral Resources,” “Indicated Mineral Resources” and “Inferred Mineral Resources” to comply with the reporting standards in Canada. SEC Industry Guide 7 does not recognize Mineral Resources and U.S. companies are generally not permitted to disclose resources in documents they file with the SEC. Furthermore, disclosure of “contained ounces” is permitted disclosure under Canadian regulations; however, the SEC only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measures. Investors are specifically cautioned not to assume that all or any part of the mineral deposits in these categories will ever be converted into SEC-defined mineral reserves. Further, “Inferred Mineral Resources” have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists. In accordance with Canadian rules, estimates of “Inferred Mineral Resources” cannot form the basis of Feasibility or Pre-Feasibility studies. It cannot be assumed that all or any part of “Mineral Resources,” “Measured Mineral Resources,” “Indicated Mineral Resources” or “Inferred Mineral Resources” will ever be upgraded to a higher category. Investors are cautioned not to assume that any part of the “Mineral Resources,” “Measured Mineral Resources,” “Indicated Mineral Resources” or “Inferred Mineral Resources” reported in this Annual Information Form is economically or legally mineable. In addition, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” under reporting standards in Canada differ in certain respects from the standards of the SEC. For the above reasons, information included in this Annual Information Form that describes our Mineral Reserves and Mineral Resources estimates is not comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of the SEC.

2019 DEVELOPMENTS

Offering of $230 Million Convertible Senior Notes

On March 19, 2019, we completed an offering of $230.0 million aggregate principal amount of 2.50% convertible senior notes due 2039 (the “2019 Notes”) for net proceeds of $222.9 million after payment of commissions and expenses related to the offering. We used $152.3 million of the net proceeds from the offering of the 2019 Notes to repurchase, in separate privately negotiated transactions, $150.0 million of our outstanding 2013 Notes.

Acquisition of 8,900 Hectares Contiguous to Marigold Mine

On June 27, 2019, we acquired approximately 8,900 hectares of land contiguous to the Marigold mine, comprised of a 100% interest in the Trenton Canyon and Buffalo Valley properties from Newmont Corporation (“Newmont”) and Fairmile Gold Mining, Inc. (“Fairmile”), net of a 0.5% net smelter returns (“NSR”) royalty on the properties. The aggregate purchase price included $22.0 million in cash and the assumption of related long-term environmental and reclamation obligations then valued at approximately $13.0 million. The acquisition of Trenton Canyon and Buffalo Valley increased the land position at the Marigold mine by 84% and provides a potential opportunity to increase mineralization.

Purchase of SilverCrest Shares

In August 2019, we completed the purchase of 780,000 common shares of SilverCrest Metals Inc. (“SilverCrest”) for total consideration of C$4,563,000, pursuant to the equity participation right under our agreement with SilverCrest. Upon closing of the transaction, we owned approximately 9.8% of the issued and outstanding common shares of SilverCrest on a non-diluted basis. As at December 31, 2019, we owned approximately 8.4% of the issued and outstanding common shares of SilverCrest on a non-diluted basis.

Acquisition of Remaining 25% Interest in Puna Operations

On September 18, 2019, we completed the acquisition of the remaining 25% interest in Puna Operations from Golden Arrow Resources Corporation (“Golden Arrow”) for aggregate consideration totaling approximately $32.4 million. The transaction allowed us to consolidate ownership in Puna Operations and streamline our reporting structure, and is expected to allow for cost savings and operational flexibility, along with near-term, low-risk silver production growth. See “Mineral Properties – Puna Operations” for further details.

2018 DEVELOPMENTS

Change to Board of Directors

On January 1, 2018, we appointed Mr. Simon A. Fish and Ms. Elizabeth A. Wademan to our Board of Directors with the objective of strengthening the Board’s expertise in the areas of international capital markets and legal and corporate governance. See “Directors and Executive Officers – Directors” for additional information on each of Mr. Fish’s and Ms. Wademan’s prior experience.

Change to Chief Operating Officer

On May 3, 2018, we announced the appointment of Mr. Kevin O’Kane as Senior Vice President and Chief Operating Officer effective June 4, 2018, replacing Mr. Alan Pangbourne, who retired at the end of May 2018. See “Directors and Executive Officers – Executive Officers” for additional information on Mr. O’Kane’s prior experience.

Updated Life of Mine Plan for the Marigold Mine

On June 18, 2018, we released an updated life of mine plan for the Marigold mine in Nevada, U.S., which outlined an anticipated mine life of over ten years based on Mineral Reserves as at December 31, 2017. We filed a technical report titled “NI 43-101 Technical Report on the Marigold Mine, Humboldt County, Nevada USA” dated July 31, 2018 with an effective date of December 31, 2017 (the “Marigold Technical Report”) in support of the updated life of mine plan. See “Mineral Properties – Marigold Mine” for further details.

Sale of Pretium Shares

As of June 30, 2018, we sold our remaining position of 9.0 million common shares of Pretium Resources Inc. (“Pretium”) for pre-tax cash proceeds of approximately $63.4 million, and no longer hold any Pretium shares.

Declaration of Commercial Production at the Chinchillas Mine

On December 1, 2018, we declared commercial production at Puna Operations’ Chinchillas mine. Development of the mine, located approximately 45 kilometers from the Pirquitas plant, commenced in early 2018 and extends the life of the Pirquitas plant through mining of ore at Chinchillas, transporting the ore to Pirquitas and processing it through the existing Pirquitas plant.

Strategic Investment in SilverCrest Metals

On December 10, 2018, we completed a transaction with SilverCrest to purchase, by way of private placement, 8,220,645 common shares of SilverCrest at a price of C$3.73 per common share for total consideration of C$30.7 million. SilverCrest owns the Las Chispas project, a high-grade development project, in Mexico.

2017 DEVELOPMENTS

Change to Chairman of the Board

On March 27, 2017, we announced that, after serving over ten years on our Board of Directors, Mr. Peter W. Tomsett decided to retire from his position of Chairman at the close of our 2017 annual and special meeting of shareholders. The Board of Directors appointed Mr. A. E. Michael Anglin to assume the role of Chairman, effective as of May 4, 2017. Mr. Anglin has served as a member of our Board since 2008. See “Directors and Executive Officers – Directors” for additional information on Mr. Anglin’s experience.

Resolution of Export Duty Claim in Argentina

We entered into a fiscal stability agreement with the Federal Government of Argentina in 1998 for production from the Pirquitas mine. In December 2007, the National Customs Authority of Argentina (Dirección Nacional de Aduanas) (“Customs”) levied an export duty of approximately 10% from concentrate for projects with fiscal stability agreements pre-dating 2002 and Customs asserted that the Pirquitas mine was subject to this duty. We had previously challenged the legality of the export duty applied to silver concentrate.

On March 31, 2017, we entered into the tax moratorium system in Argentina to resolve this long-standing dispute. Under the conditions of the moratorium, which converts the export duty liability to Argentine pesos, we have agreed to pay approximately ARS 1 billion with 5% down payment initially and the balance in installments over 60 months. Outstanding ARS amounts are subject to interest at a minimum rate of 1.5% per month. Upon completion of these payments, all liabilities related to historical export duties and interest will be extinguished. We are no longer challenging the legality of the application of the export duty other than with respect to our right for reimbursement of the $6.6 million in export duties that we paid.

Formation of Puna Operations Joint Venture

On May 31, 2017, we formed the Puna Operations joint venture with Golden Arrow comprised of our Pirquitas property and Golden Arrow’s Chinchillas properties and owned on a 75%/25% basis by each company, respectively. See “Mineral Properties – Puna Operations” for further details.

Amendment to Credit Facility

During the second quarter of 2017, we extended the maturity of our $75.0 million senior secured revolving credit facility (the “Credit Facility”) to June 8, 2020, and concurrently reduced applicable margins, increased covenant flexibility and added a $25.0 million accordion feature. Amounts that are borrowed under the Credit Facility will incur variable interest at London Interbank Offered Rate plus an applicable margin ranging from 2.25% to 3.75% determined based on our net leverage ratio. All debts, liabilities and obligations under the Credit Facility are guaranteed by certain of our material subsidiaries and secured by certain of our assets, certain of our material subsidiaries, and pledges of the securities of certain of our material subsidiaries. The Credit Facility may be used for reclamation bonding, working capital and other general corporate purposes.

Change of Name

Effective August 1, 2017, we changed our name to SSR Mining Inc. from Silver Standard Resources Inc. to better reflect our business focus as a precious metals producer.

Seabee Gold Operation PEA Supports Mine Expansion Plan

On September 7, 2017, we reported the results of a PEA for the Seabee Gold Operation, which provided a mine expansion scenario. The PEA contemplated near-term production growth, extended production to 2024, expanded operating margins and improved processing plant performance while requiring low capital investment. The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves. Consequently, there is no certainty that the results set out in the PEA will be realized. We subsequently filed the technical report entitled “NI 43-101 Technical Report for the Seabee Gold Operation, Saskatchewan, Canada” dated October 20, 2017 with an effective date of December 31, 2016 (the “Seabee Gold Operation Technical Report”) in support of the PEA. See “Mineral Properties – Seabee Gold Operation” for further details.

DESCRIPTION OF THE BUSINESS

GENERAL

We have an experienced management team of mine-builders and operators with proven capabilities. We are engaged in the operation, acquisition, exploration and development of precious metal mineral properties located in the Americas. We are committed to delivering safe production through relentless emphasis on Operational Excellence. We are also focused on growing production and Mineral Reserves through the exploration and acquisition of assets for accretive growth, while maintaining financial strength.

In addition to the Marigold mine, the Seabee Gold Operation and Puna Operations, we own two development projects: the Pitarrilla project, a silver-lead-zinc project in Mexico; and the San Luis project, a high-grade gold-silver project in Peru. We also hold interests in several other properties in North and South America at various stages of exploration.

PRINCIPAL PRODUCTS

The Marigold mine and Seabee Gold Operation produce gold in doré form. Doré is unrefined gold bullion bars usually consisting of in excess of 90% gold that is refined to pure gold bullion prior to sale to our customers, which are typically bullion banks. Puna Operations produces silver/lead and zinc concentrates, which are sold to smelters or traders for further refining. During 2019, one customer accounted for 42% (compared to 51% in 2018) of our concentrates revenue.

Our revenue by product category for the financial years ended December 31, 2019 and December 31, 2018 was as follows:

- 11 -

The market prices of gold and silver are key drivers of our profitability. The price of these metals can fluctuate widely and is affected by a number of macroeconomic factors, including but not limited to: global or regional consumption patterns; the supply of, and demand for, these metals; interest rates; exchange rates; inflation or deflation; and the political and economic conditions of major gold-producing and gold-consuming countries throughout the world.

The price of gold traded between $1,270 per ounce and $1,350 per ounce in the first two quarters of 2019 and then increased steadily until early September, recording its highest level in 2019 at $1,552 per ounce, before declining slightly to finish 2019 at $1,517 per ounce. The PM fix average of $1,393 per ounce in 2019 was higher than the 2018 average of $1,268 per ounce. The silver price trading pattern closely followed that of gold with the first two quarters of 2019 trading within a range between $14.35 and $16.00 per ounce. From July through September, the price of silver increased to its highest level in 2019 of $19.57 per ounce and closed the year at $17.83 per ounce. The 2019 average silver fix price of $16.21 per ounce was higher compared to the 2018 average of $15.71 per ounce.

SPECIALIZED SKILLS AND KNOWLEDGE

Various aspects of our business require specialized skills and knowledge, including in areas of geology, engineering, drilling, metallurgy, permitting, logistics, planning and implementation of exploration programs as well as legal compliance, finance, accounting, environmental and community relations. There remains demand for highly skilled, experienced and diverse workers in our industry. We face competition for qualified personnel with these specialized skills and knowledge, which may increase our costs of operations or result in delays. See “Risk Factors” for further details.

COMPETITIVE CONDITIONS

The precious and base metals mineral exploration and mining business is competitive. Competition is primarily for: mineral properties that can be developed and produced economically; technical experts that can find, develop and mine such mineral properties; labour to operate the mineral properties; and capital to finance exploration, development and operations.

We compete with other mining and exploration companies in the acquisition of mineral properties and in connection with the recruitment and retention of qualified employees. There is significant competition for mineral properties. Many larger competitors conduct business globally and thus have greater financial and technical resources available to them. If we are unsuccessful in acquiring additional mineral properties or qualified personnel, we may not be able to replace Mineral Reserves, maintain production or grow.

As at December 31, 2019, of the 636 full-time employees in Argentina, 376 were represented by a union.

Environmental Protection Requirements

We have certain reclamation obligations at our mineral properties, including the Marigold mine, the Seabee Gold Operation and Puna Operations. At the Marigold mine, we engage in concurrent reclamation practices and provide bonds for all permitted features, as part of the State of Nevada permitting process. Current bonding amounts are based on third party cost estimates to reclaim all permitted features at the Marigold mine, with the exception of a few features permitted as permanent, post-mining features. The Bureau of Land Management (“BLM”) and the State of Nevada both review and approve the bond estimate, and the BLM holds the financial instruments providing the bond backing. As at December 31, 2019, the Marigold mine, including the Trenton Canyon and Buffalo Valley properties, had reclamation bond requirements totaling approximately $75.2 million.

At the Seabee Gold Operation, we also have an approved closure plan and financial assurance held by the Province of Saskatchewan. The closure plan addresses all final reclamation requirements as well as the longer-term post-reclamation monitoring and maintenance phase. As required by our environmental permits, the closure plan is periodically updated. As at December 31, 2019, the Seabee Gold Operation had reclamation bond requirements totaling approximately $6.3 million.

At Puna Operations, the present value of the current closure and reclamation cost estimate, to be spent over a number of years, using a discount rate of 9.9%, is approximately $26.3 million.

We also have certain reclamation obligations at the Duthie property and the Silver Standard mine property, both located in British Columbia, Canada. In 2019, our reclamation work program at these properties was carried out at a cost of approximately $0.1 million.

See “Corporate Social Responsibility – Environment and Sustainability” and the disclosure regarding environmental matters under the respective descriptions of the Marigold mine and the Seabee Gold Operation for further details regarding environmental matters.

Foreign Operations

Any changes in regulations or shifts in political attitudes in the jurisdictions in which we operate, including Argentina, Mexico, Peru and the United States, are beyond our control and may adversely affect our business. Current and future development and operations may be affected in varying degrees by certain economic, political and other risks and uncertainties including, but not limited to: claims by governmental bodies; restrictions on production; expropriation or nationalization; employee profit-sharing requirements; foreign exchange controls; restrictions on repatriation of profits; import and export regulations; cancellation or renegotiation of contracts; changing fiscal regimes and uncertain regulatory environments; fluctuations in currency exchange rates; high rates of inflation; changes in royalty and tax regimes, including the elimination of tax exemptions; underdeveloped industrial and economic infrastructure; unenforceability of contractual rights and judgments; changes to environmental legislation; land claims of local people; and mine safety. We cannot accurately predict the effect of these factors. See “Risk Factors” for further details.

CORPORATE SOCIAL RESPONSIBILITY

For us, being a responsible corporate citizen means protecting the natural environment associated with our business activities, providing a safe workplace and work processes for our employees and contractors, and investing in the communities where we operate so that we can enhance the lives of those who work and live there beyond the life of such operations. We take a long-term view of our corporate responsibility, which is reflected in the policies that guide our business decisions, and in our corporate culture that fosters safe and ethical behavior across all levels of SSR Mining.

SAFETY AND HEALTH POLICY

Our Safety & Health Policy (the “Safety & Health Policy”) defines the organization’s safety priorities and is designed to guide us in advancing each of those priorities, and to ensure that we develop and implement effective management systems to identify, minimize and manage health and safety risks. It is also used to promote and enhance employee commitment and accountability. The Safety & Health Policy is available for viewing on our website at www.ssrmining.com.

- 13 -

HEALTH AND SAFETY

We reflect our commitment to the health and safety of our employees by creating and maintaining a safe working environment, equipment, work processes, effective safety and health management systems, and by complying with all applicable health and safety laws and regulations. We acknowledge that there are inherent risks associated with our business and, through proactive risk management, continuously strive to minimize and control these risks.

Our safety vision is “Safe for Life”, and our ultimate goal is to deliver safe production every day. We seek to ensure our employees are safe for their families and at work. Our safety framework puts emphasis on effective risk-centered management systems, positive and effective work cultures and proactive leadership to drive culture enhancement. We emphasize balancing the human and technical aspects of safety: blending leadership behaviours with traditional management activities to create a safe, productive culture. We ensure that our workers understand their individual contributions to safe production. In this way, our employees maintain safety awareness, recognize hazards and analyze risk in their daily activities. Each employee has established commitments related to their personal and work and off-the-job safety and health behaviors and is empowered to take the necessary actions to minimize risks. The technical aspects of safety are addressed by identifying and assessing job-related risks, establishing systems, policies and procedures, providing appropriate training and verifying training competencies. Performance measurement and accountability provides feedback and maintains focus on continuous improvement.

In 2019, we made a major commitment to improve leadership competencies among our line managers through the implementation of a customized leadership development system (L.E.A.D.). In addition to defining critical competencies that impact safety and operations, we commenced a long-term development program in 2019 that will be followed by additional site-specific leadership development activities designed to foster long-term leadership enhancement.

SAFETY AND SUSTAINABILITY COMMITTEE

Our Board of Directors has established a Safety and Sustainability Committee that, as part of its mandate, is responsible for reviewing our safety, health, security, risk, environment, community relations and sustainability policies and practices and monitoring our performance in these areas. The Safety and Sustainability Committee meets and reports to the Board of Directors on a quarterly basis. Our Safety and Sustainability Committee charter is available for viewing on our website at www.ssrmining.com.

ENVIRONMENTAL AND COMMUNITY POLICY

Under our Environmental & Community Policy (the “Environmental & Community Policy”), we are committed to executing our business with strong environmental and community stewardship through the development of a sustainable approach to corporate social responsibility. The Environmental & Community Policy is available for viewing on our website at www.ssrmining.com. Our Vice President, Environment and Community Relations oversees environmental management and reports directly to the Chief Operating Officer. The Chief Operating Officer reports directly to the Chief Executive Officer. Executive compensation and remuneration is based on the achievement of our corporate objectives, which include health, safety, environment and sustainability goals.

ENVIRONMENT AND SUSTAINABILITY

Our activities are subject to extensive laws and regulations governing the protection of the environment and natural resources. These laws address, among other things, emissions into the air, discharges into water, management of waste, management of hazardous substances, protection of natural resources, antiquities and endangered species and reclamation of lands disturbed by mining operations. We are required to

- 14 -

obtain governmental permits and, in some instances, provide bonding requirements under federal, state, or provincial air, water quality, and mine reclamation rules and permits. Violations of environmental laws are subject to civil sanctions and, in some cases, criminal sanctions, including the suspension or revocation of permits. The failure to comply with environmental laws and regulations could result in temporary or permanent closure of our mining operations, project development delays, material financial impacts or other material impacts to our projects and activities, fines, penalties, lawsuits by the respective government or private parties, revocability of property or material capital expenditures. Additionally, environmental laws in the countries in which we operate require that we periodically perform environmental impact studies and updates at our mines. These studies could reveal environmental impacts that would require us to make significant capital outlays or cause material changes or delays in our intended activities. See “Risk Factors”.

We comply with regulatory requirements and diligently apply appropriate methodologies to protect the environment throughout our exploration, development, mining, processing and closure activities. Our environmental obligations include, but are not limited to, obtaining and maintaining all environmental permits and approvals required for the conduct of our operations, the proper handling, storage and disposal of regulated materials and the timely and accurate submission of required reports to the appropriate government agencies.

In 2007, the Marigold mine became the first operating gold mine in the world certified as fully compliant with the International Cyanide Management Code (the “Cyanide Code”). The Cyanide Code is a voluntary industry program for companies involved in the production of gold by the cyanidation process. The Cyanide Code addresses the production of cyanide, its transport from the producer to the mine, its on-site storage and use, decommissioning and financial assurance, worker safety, emergency response, training, stakeholder involvement and verification of implementation of the Cyanide Code. The Marigold mine has been recertified in compliance with the Cyanide Code each time it has been audited by the International Cyanide Management Institute, with the fourth successful recertification occurring in 2018.

We believe that how we close a mine is just as important as how we open and operate a mine. Our commitment to excellence in mine closure is demonstrated by our highly successful and award-winning approach to closing one of our historic flagship projects, the Duthie mine in British Columbia, Canada. In recognition of our efforts and success in closing the mine, we received recognition for Outstanding Reclamation Achievement by the Technical and Research Committee on Reclamation from the Mining Association of British Columbia and the British Columbia Ministry of Energy and Mines.

COMMUNITY ENGAGEMENT

Our community relations program is based on open and continuous communication with the members of communities located in our areas of operation. We take a shared-value approach to local development activities to promote sustainable long-term economic and social benefits. In addition, we strive to ensure that local stakeholders have an opportunity for input and dialogue. Projects aimed at assisting and advancing our communities include training and employment, development of infrastructure and support for education and medical services, among others. At all times, we work to be a partner in the long-term sustainability of the communities in which we operate.

Community support and engagement is well-established at our Marigold mine, and several of our employees are key participants in local development efforts. Our employees work closely with the University of Nevada, Reno in creating a graduate program in mining, in addition to providing internships for students and ongoing support to the university. We also support local high schools through scholarships, contribution of equipment and supplies and employee volunteer efforts. In addition, our Marigold emergency response team actively supports the emergency preparedness and wellness in the local community and has participated in various activities including training drills and delivering flu vaccinations at health fairs.

Our Seabee Gold Operation is located in northern Saskatchewan, within the traditional territories of the Lac La Ronge Indian Band and the Peter Ballantyne Cree First Nation. Since our acquisition of the operation in May 2016, we have identified training, education and employment of northern communities as priorities for community engagement. This has resulted in over 35% of our employees at the Seabee Gold Operation being self-identified as indigenous and over 20% from Northern Saskatchewan communities. In 2019, we partnered with Indspire to create scholarships for Indigenous communities in the vicinity of the Seabee Gold Operation.

At Puna Operations in Argentina, we support the educational system in the Province of Jujuy through collaboration with local schools. We have assisted with the renovation of six local educational facilities and with a number of information sessions and educational activities held for students throughout the region. We have also collaborated with the Argentina Ministry of Education to create a program allowing members of local communities, including our employees, to complete their secondary education. Furthermore, we provide medical services and administer health campaigns in the remote areas in close proximity to the Pirquitas property. The Pirquitas health center provides emergency services for the local communities and we have initiated a general practitioner outreach program for local towns, commenced a dental care program and held numerous illness prevention workshops. We also built two sports centers in 2016 for the surrounding communities.

As part of the development of the Chinchillas property, we have enhanced community engagement targeting education, training and employment opportunities. Over 300 employees have been trained and are working at Chinchillas and nearly 100% of these employees are from the local communities.

At our Pitarrilla project in Mexico, as part of our agreement with the Ejido Casas Blancas, we have funded the construction of Lienzo Charro, a traditional rodeo site, and supported health and cultural activities. As part of our agreement with the Ejido San Francisco De Asís, we have funded infrastructure and cultural activities.

Over the past years at our San Luis project in Peru, we have engaged in and funded several projects aimed at developing the social and economic conditions in local communities. We are currently coordinating with the Social Management Office of the Ministry of Mining and Energy and a local university to advance a training program for local residents, including a mining internship program.

TRANSPARENCY

In 2019, we published our inaugural Sustainability Report (the “2018 Sustainability Report”), which was developed using the Global Reporting Initiative framework. The 2018 Sustainability Report outlines our approach to sustainability across a range of areas and summarizes our 2018 sustainability performance. The report also underscores our ongoing commitment to transparency with our stakeholders. The 2018 Sustainability Report is available for viewing on our website at www.ssrmining.com.

In addition, we disclose certain categories of payments we make to domestic and foreign governments at all levels under the Canadian Extractive Sector Transparency Measures Act (“ESTMA”). Our annual ESTMA reports are available on our website at www.ssrmining.com.

HUMAN RIGHTS POLICY

As part of our commitment to being a responsible corporate citizen, we recognize the important role and responsibility we have in respecting the human rights of our stakeholders. In 2019, we adopted a Human Rights Policy (the “Human Rights Policy”), which is aligned with the United Nations Guiding Principles on Business and Human Rights, the United Nations Global Compact, and the Organization for Economic Cooperation and Development Guidelines for Multinational Enterprises. This includes support and respect for the human rights expressed in the International Bill of Human Rights and the principles concerning fundamental rights set out in the International Labour Organization’s Declaration on Fundamental Principles and Rights at Work. The Human Rights Policy is available for viewing on our website at www.ssrmining.com.

In 2019, as part of our commitment to increasing awareness of our human rights commitments, we delivered internal human rights training targeted at department managers at all of our sites and offices.

DIVERSITY

Our Corporate Governance and Nominating Committee (the “CGN Committee”) has responsibility for recommending to the Board the nominees for election or re-election as directors at the annual meeting of Shareholders. As part of this process, our CGN Committee assesses the skills, expertise, experience and backgrounds of our directors annually, in light of the needs of our Board, including the extent to which the current composition of our Board reflects a diverse mix of identified competencies. Our CGN Committee charter is available for viewing on our website at www.ssrmining.com.

Our Board of Directors recognizes that a board composed of men and women with a mix of differing skills, experience, perspectives, age and characteristics leads to a more robust understanding of opportunities, issues and risks, and to stronger decision-making. In 2018, our Board of Directors adopted a Board Diversity Policy (the “Board Diversity Policy”), which promotes the benefits of, and need for, board diversity. Our CGN Committee reviews this policy annually and assesses its effectiveness in promoting a diverse Board, which includes an appropriate number of women directors. Our Board Diversity Policy is available for viewing on our website at www.ssrmining.com.

In addition, each of our Code of Business Conduct and Ethics (the “Code of Conduct”) and our Employee Assistance Program promotes and supports diversity and inclusion. Our Code of Conduct is available for viewing on our website at www.ssrmining.com.

We are committed to a merit-based system for board composition within a diverse and inclusive culture, which solicits multiple perspectives and views and is free of conscious or unconscious bias and discrimination. We are also committed to improving the gender representation of our Board, and undertake to work diligently towards, among others: achieving a Board composition by 2022 in which at least thirty percent (30%) of our directors are women; and ensuring that our CGN Committee includes women directors.

Gender diversity was a particular focus for our CGN Committee in the most recent director search process in 2017, along with the need to recruit directors to strengthen our expertise in the areas of the international capital markets, legal and corporate governance. This search resulted in the appointment of each of Ms. Elizabeth A. Wademan and Mr. Simon A. Fish to the Board, effective January 1, 2018. As of such date, and during 2019, two of our nine directors (22%) were women. We also recognize the need to promote gender diversity within our executive officer positions, and our five-member executive team includes one woman, Ms. Nadine J. Block as Senior Vice President, Human Resources (20% of our executive officers). See “Directors and Executive Officers – Executive Officers” for further information.

In March 2019, we became a member of each of the Catalyst Accord 2022 and the 30% Club Canada, diversity initiatives aimed at accelerating the advancement of women in Canada. The Catalyst Accord 2022 aims to increase the average percentage of women on boards and women in executive positions in corporate Canada to 30% or greater by 2022 and share key metrics with Catalyst to benchmark collective progress towards these goals. The 30% Club Canada works with the business community to achieve better gender balance on the boards and senior leadership of Canadian companies, and is focused on building a strong foundation of business leaders who are committed to meaningful and sustainable gender balance in business leadership.

ANTI-BRIBERY AND ANTI-CORRUPTION POLICY

Our Anti-Corruption Policy (the “Anti-Corruption Policy”) outlines the requirements that must be fulfilled by all our employees, officers and directors, as well as by any third party working for or acting on our behalf. These requirements include prohibitions against bribing government officials, making facilitation payments and commercial bribery. The Anti-Corruption Policy also provides employees with clarity regarding the following: books and records transparency; giving gifts to government officials; making political or charitable contributions; and third-party oversight and due diligence. The Anti-Corruption Policy is available for viewing on our website at www.ssrmining.com.

Notes to Mineral Reserves and Mineral Resources Table:

All estimates set forth in the Mineral Reserves and Mineral Resources table have been prepared in accordance with NI 43-101. The Mineral Reserves and Mineral Resources estimates have been reviewed and approved by Samuel Mah, P.Eng., our Director, Mine Planning, and F. Carl Edmunds, P.Geo., our Vice President, Exploration, each of whom is a qualified person as defined under NI 43-101.

All Mineral Resources are reported inclusive of Mineral Reserves. Mineral Resources which are not Mineral Reserves do not have demonstrated economic viability. Due to the uncertainty that may be attached to Inferred Mineral Resources, it cannot be assumed that all or any part of an Inferred Mineral Resource will be upgraded to an Indicated or Measured Mineral Resource as a result of continued exploration.

Mineral Reserves and Mineral Resources figures have some rounding applied, and thus totals may not sum exactly. All ounces reported herein represent troy ounces, and “g/t” represents grams per tonne. All $ references are in U.S. dollars. All Mineral Reserves and Mineral Resources estimates are as at December 31, 2019.

Mineral Reserves are estimated using the following commodity prices: $1,250 per ounce of gold; $18.00 per ounce of silver; $1.00 per pound of zinc; and $0.90 per pound of lead. Additional modifying parameters such as mine recovery, dilution, metallurgical recovery and geotechnical are appropriately taken into consideration. Mineral Resources are estimated using the following commodity prices: $1,400 per ounce of gold; $20.00 per ounce of silver; $1.30 per pound of zinc; and $1.10 per pound of lead, except as noted below for each of the San Luis project and the Amisk project.

All technical reports for the properties are available under our profile on the SEDAR website at www.sedar.com or on our website at www.ssrmining.com.

“Measured Resources”, “Indicated Resources” and “Inferred Resources” are defined under the heading “Introductory Notes – Cautionary Notice Regarding Mineral Reserves and Mineral Resources Estimates”. Although Measured Resources, Indicated Resources and Inferred Resources are Mineral Resources confidence classification categories defined by CIM and are recognized and required to be disclosed by NI 43-101, the SEC does not recognize these categories. Disclosure of contained ounces is permitted under NI 43-101; however, the SEC permits mineralization that does not constitute “reserves” by SEC standards to be reported only as in place tonnage and grade. See “Introductory Notes – Cautionary Notice Regarding Mineral Reserves and Mineral Resources Estimates”.

MARIGOLD MINE

The following disclosure relating to the Marigold mine is based on information derived from the Marigold Technical Report prepared by James N. Carver, SME Registered Member, Karthik Rathnam, MAusIMM (CP), Thomas Rice, SME Registered Member, and Trevor J. Yeomans, ACSM, P.Eng., each of whom is a qualified person under NI 43-101. Each of Messrs. Carver, Rathnam and Yeomans is an employee of SSR Mining. The Marigold Technical Report is available for review under our profile on the SEDAR website at www.sedar.com or on our website at www.ssrmining.com. All scientific and technical information relating to the Marigold mine subsequent to the effective date of the Marigold Technical Report has been reviewed and approved by Greg Gibson, P.E. and SME Registered Member, our General Manager at the Marigold mine, and James N. Carver, SME Registered Member, our Exploration Manager at the Marigold mine, each of whom is a qualified person under NI 43-101.

Project Description, Location and Access

The Marigold mine is located in southeastern Humboldt County, in the northern foothills of the Battle Mountain Range, Nevada, U.S. The mine is situated approximately five kilometers south-southwest of the town of Valmy, Nevada. Other nearby municipalities include Winnemucca and Battle Mountain, Nevada, which are located approximately 58 kilometers to the northwest and 24 kilometers to the southeast of the Marigold mine, respectively. Access to the Marigold mine is via a five kilometer long public road consisting of hard packed clay and gravel, emanating from the Exit 216 off Interstate Highway 80.

The authorized plan of operations (“PoO”) area of the Marigold mine encompasses approximately 10,600 hectares, with approximately 2,450 hectares within the PoO permitted for mining-related disturbance. Land and mineral ownership within the PoO for the mine are generally noted as having a “checkerboard” ownership pattern. In 2015, we acquired the Valmy property, a 2,844 hectare land package surrounding portions of the Marigold mine to the east, south and west. In 2018, we completed the acquisition of certain parcels of land, and the associated mineral and surface rights, proximal to the PoO boundary. In 2019, we acquired the Trenton Canyon and Buffalo Valley properties, an 8,900-hectare land package to the south and contiguous with the Marigold mine, which increased our total land holding at Marigold to 19,800 hectares. We anticipate that operating synergies and exploration benefits will be realized from the incorporation of these lands into the Marigold mine land package.

We hold a 100% interest in the Marigold mine through our wholly-owned subsidiary, Marigold Mining Company. The surface and mineral rights we hold at the Marigold mine are comprised of certain real property, unpatented mining claims, and leasehold rights to unpatented mining claims, millsite claims and certain surface lands. Such mineral claims are federally-based and managed by the BLM.

In accordance with certain of the leases in respect of which we hold leasehold interests, we are required to make certain NSR royalty payments to the lessors and comply with certain other obligations, including completing certain work commitments or paying taxes levied on the underlying properties. Such NSR royalty payments are determined based on the specific areas of the Marigold mine that gold is extracted from and are payable when the related ounces extracted from such areas are produced and sold. The NSR royalty payments for the Marigold mine vary between 2.125% and 10% of the value of gold production net of offsite refining costs. We are required to pay an annual maintenance fee to keep our mining claims in good standing.

For a discussion of permitting and environmental liabilities at the Marigold mine, see “Infrastructure, Permitting and Compliance Activities” below.

Location of the Marigold Mine

History

The following is a brief chronological description of mining that has occurred at the Marigold mine prior to our ownership:

- 23 -

On April 4, 2014, we completed the acquisition of the Marigold mine from subsidiaries of Goldcorp and Barrick for total cash consideration of $268 million after closing adjustments.

The following is a brief chronological description of mining that has occurred at the Valmy property prior to our ownership:

On September 24, 2015, we completed the acquisition of the Valmy property in Nevada, U.S., which is contiguous with our Marigold mine, for $11.5 million in cash from Newmont.

The following is a brief chronological description of mining that has occurred at the Trenton Canyon and Buffalo Valley properties prior to our ownership:

As of December 31, 2019, the historical Indicated Mineral Resources estimate for Buffalo Valley is 418,000 ounces of gold (20 million tonnes at an average gold grade of 0.65 g/t) as of December 31, 2018, based on a metal price assumption of $1,400 per ounce of gold, as reported by Newmont in its news release dated February 21, 2019. The Indicated Mineral Resources estimate disclosed by Newmont has been grossed up to illustrate 100% ownership of Buffalo Valley and is subject to rounding. Such estimate is based on Newmont data (including collar, survey, lithology and assay data), using ordinary kriging with appropriate estimation parameters in accordance with industry standards. Such estimate needs to be verified by SSR Mining by conducting detailed verification checks, including quality assurance/quality control (“QA/QC”) of location, geological, density and assay data. A qualified person for SSR Mining has not done sufficient work to classify the historical estimate at Buffalo Valley as current Mineral Resources and therefore we are not treating the historical estimate as current Mineral Resources.

- 24 -

On June 27, 2019, we completed the acquisition of the Trenton Canyon and Buffalo Valley properties in Nevada, U.S. from Newmont and Fairmile, net of a 0.5% NSR royalty on the properties. The aggregate purchase price included $22.0 million in cash and the assumption of related long-term environmental and reclamation obligations for the properties.

Geological Setting, Mineralization and Deposit Types

Regional Geology

The Marigold mine is located in north-central Nevada within the Basin and Range physiographic province, bounded by the Sierra Nevada to the west and the Colorado Plateau to the east. The western part of the North American continent has undergone a complex history of extensional and compressional tectonics from the Proterozoic through to the Quaternary. Predominantly Paleozoic rifting and basin subsidence led to the formation of thick (hundreds of meters) passive margin sedimentary sequences, and repeated inter-plate collisions caused accretion of arc related volcanics and ocean floor rocks which were pushed together with the basin sediments to form fold and thrust belts. Later extension related to subduction and back arc basin rifting resulted in the development of basin and range topography. Crustal thinning caused by the extension allowed the rise of magma close to the surface which produced extensive and voluminous magmatism from the mid Eocene to late Miocene. Crustal extension with bi-modal volcanism occurred in the region from the late Miocene to the present day.

Local and Property Geology

The Marigold mine is located in the Battle Mountain mining district on the northern end of the Battle Mountain-Eureka trend, a conspicuous lineament of sedimentary rock-hosted gold deposits. The Battle Mountain district hosts numerous mineral occurrences, including porphyry copper-gold, porphyry copper-molybdenum, skarn, placer gold, distal disseminated silver-gold, and Carlin-type gold systems.

Three packages of Paleozoic sedimentary and metasedimentary rocks are present at the Marigold mine. In ascending tectonostratigraphic order, these include:

- 25 -

A series of late Cretaceous porphyritic quartz monzonite dikes crosscut the Paleozoic rock package at the Marigold mine. The intrusions are typically several meters wide, and several can be traced along strike for tens to hundreds of meters. The dikes strike west-northwest to north and are typically steeply dipping.

There are no Mesozoic sedimentary rocks in the Marigold mine area; however, approximately two-thirds of the Marigold mine is covered by Tertiary to Quaternary intercalated gravel and volcanic material.

Mineralization

The gold deposits at the Marigold mine cumulatively define a north-trending alignment of gold mineralized rock more than 8 kilometers long. Gold mineralizing fluids were primarily controlled by fault structure and lithology, with tertiary influence by fold geometry. The deposition of gold was restricted to fault zones and quartzite-chert dominant horizons within the Valmy Formation and high permeability units within the Antler sequence. Gold mineralization was also influenced by fold geometry in the Valmy Formation.

In oxidized rocks, gold occurs natively in fractures associated with iron oxide. Rocks within the Marigold mine area are oxidized to a maximum depth of approximately 450 meters. The redox boundary is not consistent throughout the Marigold mine and is substantially influenced by lithology. Shale, argillite, and siltstone units are frequently unoxidized adjacent to pervasively oxidized quartzite horizons.

The table below provides the key stratigraphic and structural elements controlling the mineralization at each deposit:

- 26 -

Deposit Types

The deposits at the Marigold mine have been described as distal disseminated silver-gold deposits. Such deposits are disseminated equivalents of polymetallic vein deposits, characterized by a geochemical signature that includes silver, gold, lead, manganese, zinc, copper, antimony, arsenic, mercury and tellurium. Typically, they contain substantially more silver relative to gold than other types of disseminated gold deposits and may feature supergene enrichment of silver if significantly oxidized. In Nevada, distal disseminated silver-gold deposits are proximal to Jurassic, Cretaceous, and mid-Tertiary granitoid intrusions. A fundamental requirement of the distal disseminated silver-gold model necessitates a genetic link between silver-gold mineralization and causative intrusions; however, no such relationship has been conclusively demonstrated at the Marigold mine.

A Carlin-type gold deposit is a unique type of disseminated, sedimentary rock-hosted gold deposit. The genesis of Carlin-type gold deposits is currently not well understood. In Nevada, Carlin-type gold deposits occur along several main mineral trends, including the Carlin trend and Battle Mountain-Eureka trend, and are primarily hosted by silty carbonate rocks. Gold occurs in arsenian pyrite rims on pyrite grains and is associated with arsenic, sulphur, antimony, mercury and thallium. Even though the genesis of Carlin-type gold deposits remains enigmatic, there is consensus that all Carlin-type gold deposits in Nevada formed during the Eocene period.

Distal disseminated silver-gold deposits may share similarities with Carlin-type gold deposits, including ore body morphology, structural setting and alteration styles, but drastically differ with respect to alteration zonation, geochemical signature, hypogene mineralogy and endowment. Distal disseminated silver-gold deposits show a more definitive magmatic signature than Carlin-type gold deposits that includes zoning of alteration relative to felsic hypabyssal intrusions, base metal enrichment, significantly higher silver-to-gold ratios, and distinctive hypogene ore mineralogy (e.g., base metal sulfides, native gold and silver, electrum, silver sulfides and silver sulfosalts), and are typically much smaller in terms of gold endowment. Recent work suggests that the gold deposits at the Marigold mine are best classified as Carlin-type gold deposits, based on many similarities with the Carlin-type gold deposits model and a lack of evidence for causative hypabyssal intrusions.

Exploration

Subsequent to our acquisition of the Marigold mine in 2014, we initiated a review of the exploration activities conducted by previous owners. Based on this review, we initiated a gravity survey at a grid spacing of approximately 150 meters by 150 meters in areas not previously covered by a gravity survey. The main objective of this work was to delineate possible fluid conduits or feeder structures for the Marigold mineralization.

The data processing involved removal of spurious anomalies produced by dumps and leach pads. The survey successfully defined and confirmed the north-south structural zone as well as the north-east and north-west structures. Coupled with other historical geophysical programs conducted by previous owners of the Marigold mine, this information has provided a more complete structural understanding of the subsurface geology at the property to aid in our exploration program.

- 27 -

Exploration activities in 2016 included a pre-faulting reconstruction of the geology over our entire land package. This work yielded significant interpretative conclusions which identified several near-surface oxide targets. In the third quarter of 2016, we expanded our gravity survey coverage to include portions of the Valmy property and Marigold mine, including the additional lands to the east, south and west of the original Marigold mineral claims. This data, together with our understanding of the sub-surface geology, was used to select drill sites for our deep sulphide exploration program targeting a high grade style of mineralization.

In 2017, exploration and development activities included structural and compilation work at the North Red Dot target, which was tested and confirmed continuity of mineral controlling fault systems. Initial exploration of the Showdown target area yielded several encouraging intervals of shallow low grade gold mineralization between the East Basalt deposit and the Valmy deposits. The known zone of mineralization has been extended below and east of the current resource pit at East Basalt based on drill results. Positive drilling results were received within the resource portions of the Red Dot deposit, which confirmed the geologic interpretation.

Exploration activities in 2018 focused on the upgrading of Mineral Resources at Red Dot and growth within and along the various phases of the Mackay pit. Drilling also targeted Mineral Resource additions along the North and South Red Dot expansion areas.

In 2019, our Red Dot exploration program focused on geotechnical drilling and engineering with the goal of declaring additional Mineral Reserves. In the fourth quarter of 2019, we completed the second phase of confirmation drilling and, based on the results of our evaluations, we converted Mineral Resources to Mineral Reserves at Red Dot. We also conducted exploration activities in the Mackay pit, North and South Red Dot, Valmy, East Basalt and the Trenton Canyon areas aimed at extending known gold mineralization and discovery.

Drilling

Prior to our acquisition of the Marigold mine, as at December 31, 2013, a total of 6,860 drillholes for approximately 1,357,413 meters of drilling had been completed, as set out in the table below. The first hole was drilled in 1968 and drilling continued sporadically until 1985, when Cordex began systematic exploration of the 8 South area.

Prior to our acquisition of the Valmy property, Hecla, SFP Gold and Newmont completed a total of 852 drillholes for approximately 109,363 meters of drilling. Historical exploration activities conducted between 1980 and 2012 by SFP Gold and Newmont at Trenton Canyon and Horizon Gold, SFP Gold, Fairmile and Newmont at Buffalo Valley consisted of an aggregate of 2,747 drillholes totaling 341,584 meters of drilling.

Since acquiring the Marigold mine in 2014, the Valmy property in 2015 and the Trenton Canyon and Buffalo Valley properties in 2019, we have completed a total of 1,244 drillholes for 364,554 meters of drilling, as set out in the table below.

1980 to 2013 Drilling Programs

Drilling at the Marigold mine from 1985 to 1994 mainly targeted the high grade zone (greater than 1.71 grams of gold per tonne) in the 8 South deposit with a focus on gold recoverable in a mill and cyanide gold recovery circuit. In 1994, as these higher grade zones were depleted, the decision was made for the operation to migrate to a ROM heap leach operation. Consequently, the exploration strategy was adjusted to explore for and discover large tonnage ore deposits with average grades equal to or greater than 0.34 grams of gold per tonne.

Drilling activities commenced at the Valmy property in 1980 and were focused on shallow lower grade oxide mineralization amenable to ROM heap leach operations. Hecla and SFP Gold carried out drilling programs between 1980 and 1998, identifying the Valmy deposit. Exploration activities conducted by Newmont from 1998 to 2005 were mainly focused on infill drilling at the Valmy pit and also identified the Mud and NW pit deposits.

Drilling activities at the Trenton Canyon property commenced in 1980 and were focused on shallow oxide mineralization amenable to ROM heap leach operations. SFP Gold and Newmont carried out exploration activities between 1980 and 2012 identifying seven different mineral centers, including the North Peak deposit, South pit, West Pit and the Relay Ridge deposit.

In 1980, Horizon Gold commenced exploration activities at Buffalo Valley and similarly focused on shallow oxide mineralization amenable to ROM heap leap operations. Newmont advanced this project through multiple drill campaigns between 2006 and 2012.

Goldcorp and Barrick supported ongoing near mine exploration work at the Marigold mine between 2006 and 2013. This included development drilling for mineral conversion and exploration drilling to discover additional Mineral Resources. This exploration work led to the discovery of mineralization in the Red Dot area, while the development work grew the Antler and Basalt deposits into one larger open pit with discovery and definition of additional Mineral Resources near and between these two deposits. Subsequent exploration drilling campaigns have expanded on the potential for an area which encompasses the 8 South, 8 North, 8 Deep and the Terry Zone North deposits, all of which comprise the Mackay North exploration area.

2014 to 2019 Drilling Programs

In June 2014, we initiated a program of infill and exploratory RC drilling, which targeted the discovery of near-surface gold mineralization proximal to the open pits and the upgrading of Inferred Mineral Resources to Indicated Mineral Resources. From June 2014 to 2017, our drilling production included: 706 RC drillholes for 170,684 meters; 37 sonic drillholes in rock stockpiles (included in RC totals); and seven HQ diamond core holes for 7,588 meters. We drilled on targets and resource areas, including East Basalt, Battle Cry, Showdown, Valmy SE, Mud & NW, Crossfire, HideOut, 8 South pit extension, Terry Zone North, 8 Deep, 5 North, Red Dot, North Red Dot, Mackay pit extensions and the Mackay Herco Keel structure.

In 2017, exploration activities included structural and compilation work at the North Red Dot target, which was tested and confirmed continuity of mineral controlling fault systems. Initial exploration of the Showdown target area yielded several encouraging intervals of shallow low grade gold mineralization between the East Basalt deposit and the Valmy deposits. Positive drilling results were also received within the resource portions of the Red Dot deposit and in the Mackay pit expansion phases 4 and 5, which encompasses the earlier phase 1 of mining on the Mackay pit. The drilling results confirmed the working geologic understanding of the Mackay and Red Dot deposit interpretation.

The focus of our 2018 exploration program was to conduct infill drilling to upgrade Mineral Resources at Red Dot and to explore higher grade structural zones within various phases of the Mackay pit, with work also targeting Mineral Resource addition.

The main focus of our 2019 exploration program was to convert Mineral Resources into Mineral Reserves at Red Dot. We also conducted exploration drilling along areas that were north and south of Red Dot, within the Mackay pit, on Valmy target areas such as Crossfire and East Basalt, and at Trenton Canyon.

For 2020, we are planning RC and core drilling for Mineral Resources growth at Trenton Canyon, Valmy, East Basalt, Mackay, and two recently acquired small land parcels internal to the Marigold mine’s mineral claims package. This work includes diamond drilling to explore for higher-grade sulphide hosted gold deposits between East Basalt and Trenton Canyon.

Sampling, Analysis and Data Verification

Exploration activities by each of Rayrock Mines, Glamis Gold and Goldcorp have contributed the majority of the assays in the Marigold database spanning the period from 1985 to 2013. Sampling and analytical procedures are known and documented covering this period, and it is assumed that analytical information prior to 1985 has no impact on the current Mineral Resources, as those volumes containing samples collected prior to 1985 have been mined out.

Most of the samples that inform the Marigold database were generated from RC drill cuttings. In general, the practice for the collection of RC samples has changed very little since 1985; however, there have been numerous sequential improvements in sample preparation, security and analysis to date. Marigold has generally followed and continues to follow industry best practices.

There is an extensive sample storage facility at the Marigold mine that preserves the raw sample material which supports the Marigold database. Most of the laboratory pulp reject (since 1987), coarse reject (since 2006) and split diamond drill core are catalogued and securely stored in shipping containers on the property.

Sample Preparation and Analysis

Until the end of 1999, fire assay (“FA”) with a gravimetric finish was the preferred analytical method for gold in samples. Since then, all samples have been subjected to first-pass gold cyanide solution assay, which if results were greater than 0.17 grams of gold per tonne, samples were also subjected to FA determination with gravimetric finish at the onsite Marigold laboratory, or FA with atomic absorption (“AA”) spectroscopy finish and FA with gravimetric finish for over limits, at commercial laboratories.

All Newmont-provided samples that inform the resource database for the Valmy area were assayed at various commercial laboratories. The preferred assay method was FA with AA spectroscopy finish, followed by gold cyanide solution assay on select samples within the mineralized zone.

For our 2014 to 2019 drilling programs, all exploration samples from Marigold and the Valmy and Trenton Canyon properties were analyzed at American Assay Laboratories (“AAL”), an ISO 17025 certified facility in Sparks, Nevada. AAL is independent from SSR Mining. All samples are subjected to first-pass FA determination with an AA finish and FA with gravimetric finish for over-limits. This is followed by a gold cyanide solution assay with an AA finish on samples that have FA values greater than or equal to 0.03 g/t gold.

In 2019, exploration samples from Marigold and the Valmy and Trenton Canyon properties were also analyzed at Paragon Geochemical Laboratories in Sparks, Nevada. Paragon Geochemical Laboratories is independent from SSR Mining. All such samples were subjected to first-pass FA determination with an AA finish and FA with gravimetric finish for over-limits. This is followed by a gold cyanide solution assay with an AA finish on samples that have FA values greater than or equal to 0.03 g/t gold.

Quality Assurance/Quality Control Procedures

As historical QA/QC procedures at the Marigold mine did not meet current standard best practices, we collected a spatially and temporally representative selection from the well-preserved drillhole sample pulps (from the years 1987 to 2013) stored at the property and sent these to AAL for analysis. The aim of this re-assay program was to check the assay quality (i.e., accuracy and precision, from the laboratories that were used during these years). Drillhole sample pulp material was not available for the period 1968 to 1986. The 2014 pulp re-assay program returned values which did not demonstrate any systematic errors in the accuracy or precision of analytical assays from the period between 1987 and 2013. The results from the 2014 pulp re-assay program show the quality of the assay analysis only and give no indication of other potential sampling errors at any stage of the sample collection and preparation stage.

Similar to Marigold, because the historical QA/QC procedures for the Valmy property did not meet current industry standards, after our acquisition of the property, we drilled eight drillholes within a resource block of 200 meters by 150 meters. A total of eleven historical drillholes were within the same block. The infill drill comparison indicated that there was no systematic error in the historical sampling and assaying methodology when compared to current practices, and, therefore, the historical data could be used to develop the Mineral Resources for the Valmy property.

The data received from Newmont for the Trenton Canyon and Buffalo Valley properties are currently being reviewed. Appropriate data verification processes will be put in place to validate the historical database so that the historical data can be used to develop the Mineral Resources for the Trenton Canyon and Buffalo Valley properties.

As part of our QA/QC protocol for our 2014 to 2019 drilling programs, we inserted certified reference material or certified standards (“CRM”) every 20th sample, a blank sample every 50th sample and a field duplicate every 20th sample into the sampling stream. Sample data was monitored on a real-time basis (upon receipt of data from the analytical laboratory) to ensure that sample batches with control sample data were within acceptable limits and those batches outside the limits were re-submitted for analysis in a timely manner. Samples included eleven reference standard samples, unmineralized blank samples and field duplicate samples. The CRM was purchased from Rocklabs Ltd. (“Rocklabs”). Based on the results of the standard control samples, the assay data generated is unbiased and accurate, and suitable for use in our Mineral Resources estimate. Blank control samples indicated that sample cross-contamination was not an issue during the analytical work. The variability in the field duplicate control sample assays were within acceptable levels of precision.

Data Verification

For data collected after April 2014, the following verification steps were completed:

Three technical issues were identified in the Marigold Mineral Resources database, each of which has since been resolved:

There have been changes in the lower detection limit for cyanide soluble gold assays over time as the ROM cut-off grade has been reduced. Prior to 2009, assay values below detection were entered into the database as 0.0 oz/t. This data artefact was under-representing the mineralized volume of the Mineral Resources estimate at the low-grade range of the analytical distribution and contributing to the positive reconciliation experienced at the Marigold mine.

The issue of below-detection-limit analyses in the database was addressed through a systematic assay program implemented in 2015 and 2016 (the “Assay Program”). A total of 153,023 pulp samples from pre-2009 drill holes reporting a 0.0 oz/t gold cyanide soluble result and located within the reserve pits were recovered from storage and analyzed for gold at AAL. Certified standards and blanks were inserted into the pulp sample list at a rate of one standard in 20 samples and one blank in 50 samples. The samples were analyzed using a 30-gram FA with an AA finish, followed by a gold cyanide solution assay with an AA finish for those samples that returned FA results of 0.03 g/t or greater. The Assay Program identified additional mineralized areas, and the incorporation of this lower grade material, that had been previously estimated as 0.0 oz/t or deemed as waste, increased ore tonnage.

Based on the verification steps and adjustments outlined, the exploration data (including collar, survey, lithology and assay data) is suitable for use in the generation of our Mineral Resources and Mineral Reserves estimates, which can form the basis for mine planning studies.

Sample Security

The bulk of the sample values in the Marigold mine assay database are for samples analyzed at the secure on-site Marigold mine laboratory. Samples shipped off-site were either delivered to a commercial laboratory by a Marigold mine geologist or technician, or were collected by employees of the Marigold mine laboratory, and all samples were sent with a manifest listing the number of samples included in the shipment. Exploration personnel are unaware of any instances of tampering with samples either on site or in transit to the laboratory.

During our 2014 to 2019 drilling programs, all exploration samples were collected from the Marigold mine site by an employee of AAL. All sample dispatches included a manifest listing the sample identifiers and number of samples included in the shipment. AAL electronically acknowledged the receipt of the samples within 24 hours after physically reconciling the samples with the manifest. We are unaware of any instances of tampering with samples either on site or in transit to a laboratory.

Mining Operations

Marigold uses standard open pit mining methods at a current mining rate of 200,000 tonnes per day. The mine conducts conventional drilling and blasting activities with a free face trim row blast to ensure stable wall rock conditions. Electronic detonators are used to control the timing of the blasthole detonation.

Mining occurs on 15.2 meter (50 foot) benches for pre-stripping waste and 7.6 meter (25 foot) benches for ore. Loading operations are performed using three primary loading shovels. Waste and ore haulage are performed with a fleet of 25 units (300 tonne) primary haulers.

With the low grade nature of the Mineral Reserves and Mineral Resources at the Marigold mine, such large, efficient and cost effective machinery must be utilized for mining. Waste is hauled to storage locations near the mining pits to minimize haulage costs.

Processing, Recovery and Metallurgical Testing

The Marigold processing plant and facilities incorporate standard industry ROM heap leaching, carbon adsorption, carbon desorption and electro-winning circuits to produce a final precious metal (doré) product. All processing of ore, which is oxide in nature, is completed via ROM heap leach pad, and is a cost-effective method to recover the gold produced. ROM ore is delivered to the leach pad by haulage truck and stacked in 6.1 meter (20 foot) to 12.2 meter (40 foot) lifts. At any given time, approximately 0.5 million square meters of pad area is being leached.

Barren leach solution (cyanide bearing solution, very low in gold grade) is applied selectively to different areas of the pad. The leach solution is pumped to the leach pad and the pregnant solution (gold bearing) from the leach pad is then collected in a pregnant solution pond before it is pumped to carbon column trains where gold is adsorbed from solution onto activated carbon. Carbon loaded with gold is taken from the carbon columns and transported to the on-site process facility where gold is stripped from the carbon by solution. The precious metal bearing solution is passed through electro-winning cells where metals are plated out of the solution. The plated material is retorted for mercury removal and drying prior to smelting for final precious metal recovery.

Cumulative gold produced from the leach pads is equivalent to 70.3% recovery, whereas total gold recovery including recoverable gold inventory in the leach pads is estimated at 73.6%.

Infrastructure, Permitting and Compliance Activities

Infrastructure

The Marigold mine has infrastructure existing onsite for delivering power and water to the various mine shops, heap leach pads, and process and ancillary facilities. Electrical power is supplied from NV Energy, Inc. via an existing 120 kilovolt (“kV”) transmission line and routed through a 25 kV grid.

Water is supplied from three existing groundwater wells located near the access road to the property. We own groundwater rights collectively allowing up to 3.137 million cubic meters of water consumption annually, the majority of which is used as makeup water for process operations. Approximately 5.3 cubic meters per minute of fresh water is required during peak periods in the summer months. The water is primarily consumed by retention in the leach pads, evaporation, processing operations and dust suppression.

The infrastructure facilities at the Marigold mine include ancillary buildings, offices and support buildings, access roads into the plant site, source of electrical power and power distribution, source of fresh water and water distribution, fuel supply, storage and distribution, waste management and communications. The Trenton Canyon property also includes the North Peak heap leach pads and processing facilities. The Marigold mine is located in a favorable area for natural resource development with significant existing resources to support the mining industry.

Environmental, Permitting and Social Responsibility

Given that significant portions of the Marigold mine exist on public lands administered by the BLM, the BLM is the primary permitting agency and our activities undergo environmental evaluation by the BLM. Past permitting actions were conducted under BLM authority as part of the regulations under the National Environmental Policy Act (“NEPA”), which require various degrees of environmental impact analyses dictated by the scope of the proposed action.

Marigold prepared a proposed amendment to the existing PoO to permit the future mining of all pits to their planned maximum depths as part of the Mackay Optimization Project Environmental Impact Statement (“EIS”). The environmental baseline studies to support the EIS process were initiated in 2013. These baseline studies included, but are not limited to, socioeconomics, air quality impacts, cultural and archaeological resources, groundwater model, pit lake model, screen-level ecological risk assessment, waste rock/material characterization, water characterization, sage grouse habitat evaluation, evaluations for flora and fauna, and feasibility evaluation and pilot testing for rapid infiltration basins. We received a minor modification to the PoO for 2019 and approval of the EIS in the fourth quarter of 2019.

Specific federal, state and local (Humboldt County, Nevada) regulatory and permitting requirements apply to Marigold mine activities. We currently hold active, valid permits for all current facets of the mining operation. At present, there are no known environmental issues that impact our ability to extract Mineral Resources at the Marigold mine.

We have an extensive monitoring program in place at the Marigold mine for both groundwater quantity and quality, as well as seasonal surface water quantity and quality. Results from this program as well as long-term trend data is reported to both state and federal agencies. Air, geochemical, vegetation, wildlife, and industrial health monitoring are also regularly conducted according to permit requirements. Agency representatives conduct routine compliance inspections on a quarterly basis.

We engage in concurrent reclamation practices and are bonded for all permitted features of the Marigold mine, as part of the State of Nevada permitting process. Current bonding requirements are based on the Nevada Standardized Reclamation Cost Estimator and Cost Data File established by the Nevada Division of Environmental Protection (“NDEP”) to reclaim all permitted features at the Marigold mine. Both the BLM and State of Nevada review and approve the bond estimate, and the BLM holds the financial instruments providing the bond backing.

- 34 -

The State of Nevada requires a tentative closure plan to be filed when a permit application is submitted or modified, and a final closure plan to be filed two years prior to the facility actually commencing closure. Each of a tentative closure plan and reclamation permit for the Marigold mine has been filed and maintained with the NDEP, which, in conjunction with standard reclamation and re-vegetation of all disturbed areas, includes discussions on removal of infrastructure, environmental monitoring, and notably long-term process fluids/heap leach drain down solution management.

There are currently no outstanding negotiations or social requirements regarding operations at the Marigold mine. Community support and engagement is well-established and will continue, with regular updates provided by mine management to local stakeholders and regulators.

Capital and Operating Costs

The capital and operating cost estimates derived for the Marigold mine are based on a combination of the data set forth in the Marigold Technical Report and budgetary estimates, and reflect our current estimates as of December 31, 2019.

Capital costs are estimated to be $395.5 million for the life of the Marigold mine, which does not include capitalized stripping or capitalized exploration costs. The life of mine capital costs estimate is shown in the table below.

The breakdown of estimated operating costs for the life of mine, which include deferred stripping, is shown in the table below. Estimated operating costs for mine operations includes both expensed and capitalized mining costs.

Costs in individual years may vary significantly as a result of, among other things, current or future non-recurring expenditures, changes to input costs and exchange rates, and changes to our current mining operations or mine plan.

Exploration, Development and Production

Gold production at the Marigold mine is expected to increase in 2020 compared to 2019 as the mine benefits from an additional hydraulic loading unit purchased in 2019, expected to be commissioned in the first quarter of 2020, and continued operational efficiencies. Capital investments are expected to total $60.0 million, including $12 million for two replacement haul trucks and $15 million for an additional leach pad to be built in 2020. Capitalized stripping is expected to total $20 million with the majority incurred through the first three quarters of the year. Exploration expenditures totaling $12 million are expected to focus on drill programs at Mackay, Basalt, Valmy and Trenton Canyon with the goals of adding Mineral Reserves and defining additional Mineral Resources within these areas. Exploration expenditures include $2 million for drill testing Trenton Canyon’s sulphide targets.
