McEwen Mining: Q2 2021 Results

TORONTO, Aug. 04, 2021 - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) today reported its second quarter (Q2) and first half (H1) results for the period ended June 30^th, 2021.

• Our operations delivered strong production results in line with our expectations, and we are on track to meet our 2021 production guidance of 141,000 to 160,400 GEOs.
  
  
• We continue to execute on our turnaround strategy and have made significant progress both from an operational and a financial perspective (see Tables 1-3 below). We expect this trend to continue to the remainder of 2021, as the Froome mine at the Fox Complex reaches commercial production in Q4.
  
  
• On July 6, 2021, we announced that a subsidiary that holds 100% of the Los Azules copper project will be raising financing for the continued development of that project, as well as to fund a modest exploration program for its Elder Creek copper exploration property in Nevada. McEwen Copper is seeking to raise up to $80 million in a private offering and Rob McEwen has committed the first $40 million dollars.
  
  
• Our quarterly webcast will take place on Thursday, August 5^th at 2 pm EDT. Please see the details below.

Operations Update

Gold Bar Mine, USA (100% Interest)

Gold Bar produced 14,100 GEOs in Q2 at total cash costs⁽²⁾ and all-in sustaining costs (AISC)⁽²⁾ of $1,463 and $1,619 per GEO sold, respectively. This compares to 6,100 GEOs in Q2 2020 at total cash costs and AISC of $1,772 and $2,462 per GEO, respectively. The cost decrease is driven by the increase in production and by the significant operational improvements we have been continuing to work through over the past year. We expect to see this trend continue into the second half of 2021.

Exploration is focusing on testing near-mine targets and further defining oxide resources on the neighboring Tonkin property. During the quarter we incurred exploration expenses of $1.3 million of a total $5.0 million budget for 2021.

Fox Complex, Canada (100% Interest)

Black Fox produced 7,100 GEOs in Q2 at total cash costs and AISC of $917 and $1,088 per GEO sold, respectively. This compares to 2,200 GEOs in Q2 2020 at total cash costs and AISC of $3,121 and $3,332 per GEO, respectively. Mining has transitioned to the Froome deposit and is performing to plan, commercial production expected in Q4 2021.

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. During the quarter we incurred exploration expenses of $3.5 million of a total $9.0 million budget for 2021.

A Preliminary Economic Assessment (PEA) to expand the production from the Fox Complex is expected to be released in the second half of the year, following additional drilling and resource estimate updates at the Stock and Grey Fox properties.

San Jos? Mine, Argentina (49% Interest)

Our attributable production from San Jos? in Q2 was 9,300 gold ounces and 607,000 silver ounces, for a total of 18,200 GEOs⁽³⁾. For Q2, total cash costs and AISC were $1,105 and $1,500 per GEO sold, respectively. This compares to 9,000 GEOs in Q2 2020 at total cash costs and AISC of $1,280 and $1,476 per GEO, respectively. In Q2 2020, operations at San Jos? were adversely impacted by government-imposed COVID-19 restrictions.

We received $2.6 million and $7.6 million in dividends in Q2 and H1, respectively, compared to $0.3 million dividends received during the same periods in 2020.

El Gallo Project, Mexico (100% Interest)

In Q2, El Gallo produced 1,300 GEOs from residual leaching of the heap leach pad. Incremental residual leaching cost for the period was $2.7 million⁽⁴⁾. The residual leaching activities at El Gallo are expected to wind down in early 2022.

Los Azules Copper Project, Argentina (100% Interest)

On July 6, 2021, we announced the formation of a wholly-owned subsidiary to hold the Los Azules Copper project ("McEwen Copper") and to raise financing to advance the project to a preliminary feasibility study and to construct a road to the project providing year-round access compared to the current 5-month seasonal access window. McEwen Copper will hold the Los Azules assets as well as the Elder Creek exploration project in Nevada. McEwen Copper is seeking to raise up to $80 million in a private offering.

Table 4 below provides production and cost results for Q1, Q2 and H1 2021 and comparative results from 2020:

Notes:

1. Gold Equivalent Ounces (GEOs) are calculated based on a gold to silver price ratio of 68:1 for Q1 and Q2 2021, 94:1 for Q1 2020, 104:1 for Q2 2020, and 75:1 for full year 2021 Production Guidance.
2. 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 a description 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^st, 2020 filed on EDGAR and SEDAR.
3. Represents the portion attributable to us from our 49% interest in the San Jos? Mine.
4. 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.

COVID-19
All our operations have implemented rigorous health and safety measures to prevent the spread of the COVID-19 virus. Currently, the COVID-19 pandemic is not materially affecting our operations, or our future plans and objectives.

Reliability of Information Regarding San Jos?
Minera Santa Cruz S.A., the owner of the San Jos? Mine, is responsible for and has supplied to the Company all reported results from the San Jos? Mine. McEwen Mining's joint venture partner, a subsidiary of Hochschild Mining plc, and its affiliates other than MSC do not accept responsibility for the use of project data or the adequacy or accuracy of this release.

Technical Information
The technical contents of this news release have been reviewed and approved by G. Peter Mah, P.Eng., COO of McEwen Mining and a Qualified Person as defined by Canadian Securities Administrators National Instrument 43-101 "Standards of Disclosure for Mineral Projects."

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 dor? 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 Quarterly Report on Form 10-Q for the quarter ended June 30, 2021.

Cash Gross Profit
Cash gross profit is a non-GAAP financial measure and does not have any standardized meaning under GAAP. 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 or loss. Cash gross profit is calculated by adding back the depreciation and depletion expense to gross profit or loss. A reconciliation to gross profit, the nearest U.S. GAAP measure is provided in McEwen Mining's Quarterly Report on Form 10-Q for the quarter ended June 30, 2021.

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 dor? 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 Quarterly Report on Form 10-Q for the quarter ended June 30, 2021.
