MCEWEN MINING: 2021 Outlook and 2020 Year End and Q4 Results
TORONTO, March 11, 2021 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) today reported fourth quarter and full year results for the period ended December 31, 2020, along with the outlook for 2021.
“2020 was a brutal year but we more than survived and have come out stronger from it. The ‘Going Concern Note’ has been removed from our financial statements; we released two feasibility studies that shows the potential to extend the life of our Mexican operations by 9.5 years, and outlines a 6-year life for our Gold Bar mine, which recovered from what was tantamount to a near-death experience for the operation in early 2020. The future of our Fox Complex is becoming more visible. Access to the Froome deposit is nearly complete and commercial production is planned to start in Q4. This will extend the life of the Black Fox mine by 2.5 years, providing a bridge to our second phase of growth at Fox, which we will unveil in Q2. Given our large gold resource base in the Timmins area, we expect it to support a potential ten-year mine life with annual production of 100-150,000 ounces of gold.
Our recent financings in late 2020 and early 2021 were met with huge market demand and more importantly have supplied us with adequate funds for our key development projects and exploration programs in 2021. We currently have liquid assets of $49 million! Finally, we extended the maturity date of our debt from August 2021 to August 2023, with a supportive lending partner.
Beneficial developments that we welcomed, but were beyond our control, were the massive increases in the prices of silver and copper and the resultant increase in the values of our silver and copper assets. For example, using the current price of copper in the financial model from our 2017 Preliminary Economic Assessment of Los Azules, we arrive at a Net Present Value, discounted at 8%, of approximately $5 billion. In respect of the potential value of our silver assets, if we combine the San José mine and the Fenix Project, it could potentially represent a medium-sized silver producer. One investment banker we spoke to suggested the value of such a company could be a minimum of $140 million. We believe that there is significant value to be realized by spinning these assets out in two separate vehicles. In this manner we could raise the necessary capital to advance these properties, while maintaining a large shareholding. I believe that the shares of these new companies will grow in value along with the growth in demand for these metals, on the back of the green technology movement. Specifically, the electrification of transportation, renewable energy technologies and the continuing urbanization of Asia and Africa.
While I am deeply pained by our awful financial performance in 2019 and 2020, I recognize that those years are behind us and the past cannot be changed, but we can and are shaping a better future. This year will not be stellar as we continue to fix operating issues and continue to invest in exploration and business systems - the foundations for a strong mining company. Looking beyond this year, myself and our entire senior management team, many of which are new hires, feel very optimistic about the company’s growth and are committed to delivering it to you!
Let me leave you with one last thought. As you know our stock symbol is MUX and here is what we are striving to make it mean – Motivated, United, Xceptional” commented Rob McEwen, Chairman & Chief Owner.

- For the full year 2020, production was 114,800 gold equivalent ounces(1) (GEOs)(see Table 1), compared to 174,400 GEOs in 2019.
Our consolidated net loss in 2020 of $152.3 million, or $0.38 per share (see Table 2) relates primarily to the impairment for the Gold Bar Mine of $83.8 million; investment of $27.5 million on advanced projects and exploration; a gross loss of $27 million from our operations; and general and administrative costs of $9 million.
- Our three 100%-owned mines generated a cash gross loss of $4.0 million(2) in 2020, and a gross loss of $27 million. Cash gross profit (loss) is calculated by adding back depletion and depreciation to gross profit (loss).
- We are forecasting our 2021 gold equivalent production to be in the range of 141,000 to 160,400 GEOs(1) a 23% to 40% increase over 2020.
- At Black Fox, development of the vent drive that will provide initial access to the Froome underground deposit has advanced 95% by the end of February 2021. We are on track to reach the main deposit before the end of March, and complete the necessary development work to allow for commercial production to be achieved by the fourth quarter of 2021.
- Gold Bar Feasibility Study Update was filed in February 2021. Using a $1,500/oz gold price the NPV(8%) is $55.2 million, over a 6-year mine life. Probable gold reserves estimated at December 31, 2020 were 300,000 oz (Table 3.2). Exploration programs are ongoing with the objective of extending the mine life beyond 6 years.
- Fenix Feasibility Study was filed in February 2021. Using a $1,500/oz gold price and $17/oz silver price the NPV(8%) is $32 million, over a 9.5-year mine life. Fenix has the key permits towards construction.
- The Grey Fox project’s Indicated resource estimate was updated in April 2020, increasing 43% to 888,000 oz Au at 7.1 g/t (see Table 2.4). An independent preliminary economic study on expanding production at the Fox Complex is expected to be completed by the end of Q2.
- In 2020, we completed 43,000 feet (13,000 meters) of drilling at Black Fox, and 111,000 feet (34,000 meters) of drilling at Gold Bar.
- Cash and liquid assets(2) at March 10th, 2021 was $49 million.
- Our year-end conference call will take place today, Thursday, March 11th at 11am EST. Details are provided below.
Operations Update
Black Fox Mine, Canada (100% Interest)
Production from Black Fox in 2020 was 24,400 GEOs. Total cash costs and AISC were $1,397 and $1,650 per GEO, respectively.
We incurred $6.5 million in 2020 for exploration initiatives, compared to $25.8 million in 2019. We remain focused on our principal exploration goal of cost-effectively discovering and extending gold deposits adjacent to our existing operations to contribute to near-term gold production.
The Froome deposit, which is part of the Fox Complex, is accessed from two declines starting at the Black Fox pit and is situated approximately one-half mile west of the Black Fox mine. The mineralized material from Froome will be hauled approximately 20 miles (32 km) to the Stock Mine mill, where it will be processed. Development of the vent drive that will provide initial access to the Froome underground deposit has advanced 95% by the end of February 2021. We are on track to reach the main deposit before the end of Q1 and to complete the necessary development work required to achieve commercial production by the fourth quarter of 2021.
The Stock exploration area sits adjacent to our Stock mill, which currently processes ore from our Black Fox mine. The Stock West mineralized zone was discovered in mid-2019; in 2020 five drill rigs completed 53,600 feet (16,350 meters) of follow-up drilling. Initial results suggest the potential to define a significant new zone of mineralization 800m (1/2 mile) from our Stock processing facility. The majority of our 2020 drilling was designed to infill the gaps between our encouraging 2019 intercepts. This will increase the density of the data needed to develop a 3D model and the Company expects to generate an initial resource estimate while drilling continues. Four contracted drill rigs completed a total of 58,600 feet (17,900 meters) by year-end. Drilling resumed in early January 2021. Assuming this drilling is successful in identifying sufficient gold to support a decision to re-open the historic Stock Mine, we are well positioned to act quickly and begin dewatering the mine in the second half of 2021. Previously the mine was dewatered in just 4 months.
In April 2020, the Indicated resource estimate for Grey Fox project increased 43% to 888,000 oz Au at 7.1 g/t. We have engaged an independent engineering group to complete a Preliminary Economic Assessment (PEA) on the Grey Fox - Black Fox, Stock and Timmins resources utilizing our existing central milling capacity. We plan to grow annual production at the Fox Complex to 100-150,000 ounces of gold, at a targeted cash cost of $800/oz and an all-in sustaining cost (AISC) of $1,100/oz, over a +10-year life, with production envisioned to start ramping up from 2022. The PEA’s completion is expected in Q2, and will support the optimal business case on which to further complete a feasibility study. Mining from the Froome deposit, as described above, is expected to bridge gold production, providing cash flow while we continue to drill and assess additional potential resources at the Black Fox, Grey Fox, Stock and Timmins projects for future development towards expanded production.
Gold Bar Mine, USA (100% Interest)
Gold Bar produced 28,000 GEOs in 2020. Total cash costs and AISC were $2,106 and $2,459 per GEO, respectively.
The outbreak of the COVID-19 pandemic had a significant impact on 2020 production, as the Gold Bar operation shut down in Q2 and isolation quarantine protocols reduced operating shifts in Q4 after site personnel tested positive for COVID-19. The slower ramp up to full mining rates following the shutdown was primarily due to delays related to mining contractor rehiring of operators.
In 2020, we spent $5.1 million on exploration activities in and around the Gold Bar mine, which included 110,500 feet (33,700 m) of drilling and metallurgical testing to support the updated reserve estimates. Drilling at Gold Bar South has successfully advanced the project and is expected to contribute to Gold Bar mine’s future production. Subject to the receipt of permit approvals as planned, the mining of Gold Bar South could begin as early as Q1 2022.
In January 2021, updated resource model and resource and reserve estimates were completed, providing us with a more accurate model to plan from moving forward. Remodeling of these deposits has been completed in-house and reviewed by an independent third-party mining consultant. Optimization of the reserve will continue into 2021, to improve ore deliveries to the pad.
San José Mine, Argentina (49% Interest)
Our attributable production from San José in 2020 was 31,800 gold ounces and 2,013,000 silver ounces, for a total of 54,500 GEOs. Total cash costs(2) and all-in sustaining costs (AISC)(2) were $1,233 and $1,514 per GEO, respectively.
Gold and silver production decreased significantly in 2020 as a result of suspensions of mining activities due to COVID-19 combined with operating below capacity during ongoing countrywide travel restrictions.
In 2021, our partner Hochschild Mining is planning a significant exploration program at San José. Towards the end of 2020 drilling started to return encouraging results in the Saavedra area close to where mining takes place. During Q1 2021, 6,500 ft (2,000 m) of resource drilling is planned at the Betania and Isabel veins, with campaigns also continuing at the Telken zone close to Newmont’s Cerro Negro mine and at Aguas Vivas, north-west of San José.
El Gallo Project, Mexico (100% Interest)
Production from El Gallo in 2020 was 8,000 GEOs from residual leaching of the heap leach pad. During 2020, residual leaching costs were $11.4 million, or $1,409 per GEO sold.
For 2021, we expect to recover 4,500-5,900 GEOs from residual leaching of the heap leach pad.
COVID-19 Update
McEwen Mining continues to maintain wide-ranging prevention measures for its workforce and neighboring communities, including screening, physical distancing, travel restrictions, contact tracing and avoiding exposure for at-risk individuals.

Notes:
- 'Gold Equivalent Ounces' are calculated based on a gold to silver price ratio of 85:1 for Q4 2019, 77:1 for Q4 2020, 84:1 for 2019, and 89:1 for 2020. 2021 production and cost guidance is calculated based on 75:1 gold to silver price ratio.
- Cash gross profit, cash costs per ounce, all-in sustaining costs (AISC) per ounce, and liquid assets are non-GAAP financial performance measures with no standardized definition under U.S. GAAP. For definition of the non-GAAP measures see "Non-GAAP Financial Measures" section in this press release; for the reconciliation of the non-GAAP measures to the closest U.S. GAAP measures, see the Management Discussion and Analysis for the year ended December 31, 2020 filed on Edgar and SEDAR.
- Gold Bar started commercial production on May 23, 2019.
- Represents the portion attributable to us from our 49% interest in the San José Mine.
- Both cash costs and AISC per GEO no longer represent key metrics used by management to evaluate residual leaching at the El Gallo Project. For this reason, the Company has ceased relying on, and disclosing, cash costs and all-in-sustaining costs per ounce as a key metric.

Resource and Reserve Updates
The following statements apply to information contained in the resource and reserve tables below:
- Mineral Resources are inclusive of Mineral Reserves;
- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that any part of the Mineral Resources estimated will be converted into a Mineral Reserves estimate;
- Numbers in the tables have been rounded to reflect the accuracy of the estimates and may not sum due to rounding;
- The Inferred Mineral Resource in these estimates has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration;
- Quantity and grade of reported Inferred resources are uncertain in nature and there has been insufficient exploration to classify these Inferred resources as Measured or Indicated;
- Mineral Resources and Reserves were estimated using the guidelines set out in the CIM Definition Standards for Mineral Resources and Reserves prepared by the CIM Standing Committee on Reserve Definitions, reserves estimates are also compliant with SEC Industry Guide 7;
San José Mine
Hochschild Mining Plc (“Hochschild”), our joint venture partner, prepared the mineral resource and mineral reserve estimates for the San José mine as at December 31, 2020.

CAUTIONARY NOTE TO US INVESTORS REGARDING RESOURCE ESTIMATION
McEwen Mining presently prepares its resource estimates in accordance with standards of the Canadian Institute of Mining, Metallurgy and Petroleum referred to in Canadian National Instrument 43-101 (NI 43-101). These standards are different from the standards permitted in reports filed with the SEC under Industry Guide 7 (“Guide 7”). Under NI 43-101, McEwen Mining reports measured, indicated and inferred resources, measurements which are generally not permitted in filings made with the SEC under Guide 7. The estimation of measured and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves. U.S. investors are cautioned not to assume that any part of measured or indicated resources will ever be converted into economically mineable reserves. The estimation of inferred resources involves far greater uncertainty as to their existence and economic viability than the estimation of other categories of resources. Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be legally or economically mined.
Canadian regulations permit the disclosure of resources in terms of “contained ounces” provided that the tonnes and grade for each resource are also disclosed; however, under Guide 7, the SEC only permits issuers to report “mineralized material” in tonnage and average grade without reference to contained ounces. Under Guide 7, the tonnage and average grade described herein would be characterized as mineralized material. We provide such disclosure about our properties to allow a means of comparing our projects to those of other companies in the mining industry, many of which are Canadian and report pursuant to NI 43-101, and to comply with applicable disclosure requirements.
CAUTIONARY NOTE REGARDING NON-GAAP MEASURES
In this release, we have provided information prepared or calculated according to United States Generally Accepted Accounting Principles (“U.S. GAAP”), as well as provided some non-U.S. GAAP ("non-GAAP") performance measures. Because the non-GAAP performance measures do not have any standardized meaning prescribed by U.S. GAAP, they may not be comparable to similar measures presented by other companies.
Cash Costs and All-in Sustaining Costs
Cash costs consist of mining, processing, on-site general and administrative costs, community and permitting costs related to current operations, royalty costs, refining and treatment charges (for both doré and concentrate products), sales costs, export taxes and operational stripping costs, and exclude depreciation and amortization. All-in sustaining costs consist of cash costs (as described above), plus accretion of retirement obligations and amortization of the asset retirement costs related to operating sites, sustaining exploration and development costs, sustaining capital expenditures, and sustaining lease payments. Both cash costs and all-in sustaining costs are divided by the gold equivalent ounces sold to determine cash costs and all-in sustaining costs on a per ounce basis. We use and report these measures to provide additional information regarding operational efficiencies on an individual mine basis, and believe that these measures provide investors and analysts with useful information about our underlying costs of operations. A reconciliation to production costs applicable to sales, the nearest U.S. GAAP measure is provided in McEwen Mining's Annual Report on Form 10-K for the year ended December 31, 2019.
Cash Gross Profit
Cash gross profit is a non-GAAP financial measure and does not have any standardized meaning. We use cash gross profit to evaluate our operating performance and ability to generate cash flow; we disclose cash gross profit as we believe this measure provides valuable assistance to investors and analysts in evaluating our ability to finance our ongoing business and capital activities. The most directly comparable measure prepared in accordance with GAAP is gross profit. Cash gross profit is calculated by adding depletion and depreciation to gross profit. A reconciliation to gross profit, the nearest U.S. GAAP measure is provided in McEwen Mining's Annual Report on Form 10-K for the year ended December 31, 2019.
Liquid assets
The term liquid assets used in this report is a non-GAAP financial measure. We report this measure to better understand our liquidity in each reporting period. Liquid assets is calculated as the sum of the Balance Sheet line items of cash and cash equivalents, restricted cash and investments, plus ounces of doré held in precious metals inventories valued at the London PM Fix spot price at the corresponding period. A reconciliation to the nearest U.S. GAAP measure is provided in McEwen Mining's Annual Report on Form 10-K for the year ended December 31, 2019.
