TORONTO, March 16, 2020 (GLOBE NEWSWIRE) -- McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) today reported fourth quarter and full year results for the period ended December 31, 2019.
- For the full year 2019, production was 174,420 gold equivalent ounces(1) (GEOs)(see Table 1), compared to 175,640 GEOs in 2018.
- Our three 100% owned mines generated a cash gross profit of $33.7 million(2) in 2019, and a gross profit of $9.0 million. Cash gross profit, is a new non-GAAP measure used for the first time in our Form 10-K, and is intended to evaluate our ability to generate cash flow. Cash gross profit is calculated by adding back depletion and depreciation to gross profit, which is a GAAP measure.
- We received $8.9 million in dividends from our interest in the San José mine in 2019 (49% owned).
- We invested $47.3 million on advanced projects and exploration in 2019, which contributed to our consolidated net loss of $59.7 million, or $0.17 per share.
- We performed 132 miles (213 km) of drilling in 2019, with approximately 90% completed at the Black Fox Complex, and the balance at the Gold Bar Property.
- A review of the Gold Bar reserve estimate is ongoing, and a downward revision of the reserve estimates is anticipated (see the Gold Bar Mine section below for further details).
- The Grey Fox project Indicated resource estimate increased 33% (see Table 2.4).
- Exploration delivered many high-grade drill intersections on extensions of the Black Fox Mine, in the Grey Fox area, and on the Stock Property, where drilling led to the discovery of a new gold mineralized zone at Stock West.
- Our year-end conference call will take place tomorrow, Tuesday, March 17th at 2pm EDT. Details are provided below.
Operations Update
San José Mine, Argentina (49% Interest)
Our attributable production from San José in 2019 was 51,684 gold ounces and 3,354,487 silver ounces, for a total of 91,654 GEOs. Compared to 2018, gold and silver production increased 9% and 11%, respectively, primarily due to approximately 10% higher average metal grades of processed ore. For 2019, total cash costs(2) and all-in sustaining costs (AISC)(2) were $867 and $1,140 per GEO, respectively. During 2019, we received $8.9 million in dividends from our interest in San José, compared to $10.4 million in dividends received during 2018.
Production guidance for 2020 on a 49% basis is 45,700 gold ounces and 3,200,000 silver ounces, for a total of 82,000 GEOs. For 2020, cash costs and AISC are projected to be between $950-$1,000 and $1,200-$1,250 per GEO, respectively.
In addition to exploration drilling at the mine itself, exploration of the San José land package is planned to include a Titan deep penetrating geophysical survey, drilling at the Telken target close to Newmont’s Cerro Negro mine, and an assessment of other regional opportunities in the southern part of the property.
The mineral resource and reserve estimates for the San José mine have been updated (Tables 1.1 and 1.2) to reflect mine depletion and additions from exploration.
Black Fox Mine, Canada (100% Interest)
Production from Black Fox in 2019 was 35,721 GEOs. Compared to 2018, gold production decreased by 27%, due to operational challenges in the year and depleting reserves. For 2019, total cash costs and AISC were $825 and $1,225 per GEO, respectively.
Our exploration activities during 2019 included 489,000 feet (149,000 m) of surface-staged diamond drilling, and 57,000 feet (17,500 m) of underground-based exploration drilling. We invested $25.5 million in 2019 on exploration across the Black Fox Complex, compared to $22.0 million in 2018.
Development of underground access to the Froome ore body, located approximately 3,000 ft (900 m) away from the Black Fox open pit, commenced in December 2019. Mining from Froome is scheduled to begin in Q4 2021, and continue to 2023.
A feasibility study examining the development of the Grey Fox deposit by open pit mining methods is being started, and is expected to be complete in Q4 2020. Additionally, to further expand future production potential, we are considering dewatering the Stock Mine to enable us to drill the Stock West discovery and the depth extension of the mine from underground.
Production guidance for 2020 is 35,000-40,000 GEOs at cash costs and AISC of between $1,000-$1,150 and $1,150-$1,250 per GEO, respectively. Higher cash costs reflect the impact of development and related costs being expensed over the short mine life.
The mineral resource and reserve estimates for the Black Fox mine have been updated (Tables 2.1 to 2.4) to reflect mine depletion, additions from exploration, and the deletion of certain resource blocks that are deemed inaccessible due to prior mining activity. The mineral resource for the Stock East and Grey Fox projects were updated and increased.
Gold Bar Mine, USA (100% Interest)
Gold Bar produced 30,712 GEOs in 2019. The ramp-up to commercial production saw delays that adversely impacted our gold production in the first half of 2019. Gold Bar production increased during Q3, while production in Q4 was impacted by lower throughput at the crushing plant and lower grades as mining transitioned to the Gold Pick West open pit. In 2019, cash costs and AISC were $1,101 and $1,282 per GEO, respectively.
With respect to our operational experience at Gold Bar, the majority of material mined during 2019 was from the Cabin Creek pits, which has reconciled positively to our block model for both gold grade (+18%) and contained gold ounces (+8%), but negatively for ore tons (-8%). The recent transition to mining from the Gold Pick West pit has returned lower ore tons, gold grade and contained ounces from the upper benches as compared to the block model. This appears to be due to greater structural control of the mineralization than was previously expected, but which is now exposed in the newly developed pit. In light of the significant differences recently observed between the modeled (expected) and mined (actual) ore tonnage and gold grade from the Gold Pick West pit, the reserve estimate for the Gold Pick deposit as at December 31, 2018 and the future mine plan is being evaluated.
Remodeling of the Gold Pick deposit is underway by independent engineers and preliminary iterations suggest that a significant reduction in ore tonnage, partially offset by an increase in ore grade, and a resulting significant reduction in contained gold ounces from the 2018 reserve estimate is likely.
The impact on our operations for 2020 is that we expect to place fewer gold ounces than originally planned on the heap leach pad, reducing our planned production for the year.
We will publish the revised mineral reserve estimate as soon as it is completed, and a new mine plan, if necessary, will be implemented thereafter. At this time, we do not have sufficient information to provide accurate 2020 production or cost guidance for Gold Bar.
In 2019, we spent $7.2 million on exploration activities at the Gold Bar Complex, compared to $5.2 million spent in 2018. The mineral resource estimate for the Gold Bar South satellite deposit has been updated (Table 3.1).
We are working to complete the permitting and engineering work required to bring Gold Bar South into the mine plan. Additional drilling is planned over the north and south extensions of the deposit, which remain open.
El Gallo Project, Mexico (100% Interest)
Production from El Gallo in 2019 was 16,333 GEOs from residual leaching of the heap leach pad. Beginning with Q4 2019, we have ceased relying on, and disclosing, cash costs and AISC per GEO as key metrics for El Gallo because those measures include the expensing of accumulated heap leach pad inventory costs, which are not informative when accessing the current economics of residual leaching. We estimate that residual leaching will continue for as long as incremental revenue exceeds incremental costs. During 2019, residual leaching costs were $11.6 million, or $688 per GEO sold.
For 2020, we expect to recover 12,000 GEOs from residual leaching of the heap leach pad.

Notes:
- 'Gold Equivalent Ounces' are calculated based on a 75:1 gold to silver price ratio for periods up to and including Q1 2019, 88:1 for Q2 2019, 87:1 for Q3 2019, and 85:1 for Q4 2019. 2020 production and cost guidance is calculated based on 88:1 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, 2019 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
Mineral resources have been updated for the Gold Bar South (Nevada), Stock and Grey Fox Projects (Ontario), and resources and reserves have been updated for the Black Fox Mine (Ontario), and San José Mine (Argentina). For a summary of all McEwen Mining’s resources and reserves refer to the tables on our website.
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 Resource and Reserve Update
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, 2019.
These figures, reported on a 100% basis, were prepared by Hochschild and audited by P&E Mining Consultants Inc. whose audit letter dated February 10, 2020, concluded that the estimates for the San José mine prepared by Hochschild at December 31, 2019 provide a reliable estimation of reserves and resources. The reserves as presented are in-situ and include mining dilution and mining losses, however they do not include allowances for mill or smelter recoveries.

Technical Information
The technical contents of this news release has been reviewed and approved by Chris Stewart, P.Eng., President & COO of McEwen Mining and a Qualified Person as defined by Canadian Securities Administrators National Instrument 43-101 "Standards of Disclosure for Mineral Projects."
The technical information in this news release related to resource and reserve estimates has been reviewed and approved by Luke Willis, P.Geo., McEwen Mining’s Director of Resource Modelling and Qualified Person as defined by Canadian Securities Administrators National Instrument 43-101 "Standards of Disclosure for Mineral Projects."
CAUTIONARY NOTE TO US INVESTORS REGARDING RESOURCE ESTIMATION
McEwen Mining Inc. is required to prepare reports under the Securities Exchange Act of 1934 and the Canadian Securities Administrators’ National Instrument 43‑101 “Standards of Disclosure for Mineral Projects” (“NI 43‑101”), under the Canadian securities laws because we are listed on the Toronto Stock Exchange (“TSX”) and subject to Canadian securities laws. Standards under NI 43-101 are materially different than the standards generally permitted in reports filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”).
Under NI 43‑101, we report measured, indicated and inferred resources, which are measurements that are generally not permitted in filings made with the SEC. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves under Industry Guide 7. 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, the SEC only permits issuers to report “mineralized material” in tonnage and average grade without reference to contained ounces. Under U.S. regulations, 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.
