Operating and Financial Highlights

Production Costs

Total cash costs, all-in sustaining costs (AISC) and all-in costs per gold equivalent ounce sold for Q2 2015 on a consolidated basis were $713, $1,048 and $1,151 per ounce, respectively. Total cash costs and AISC at our El Gallo Mine totaled $351 and $546 per gold equivalent ounce respectively. Total cash costs and AISC at the San José Mine were $933 and $1,215 per gold equivalent ounce, respectively. The year over year decrease in total cash costs per gold equivalent ounce sold is due to higher average gold grade mined and processed at the El Gallo Mine and improved processing efficiencies.

Production

Gold equivalent production in Q2 2015 totaled 39,164 ounces, which includes 21,839 gold equivalent ounces attributable to us from our 49% interest in the San José Mine in Argentina, and 17,325 gold equivalent ounces from the El Gallo Mine in Mexico. Production increased year-over-year due to higher grades and better recoveries at the El Gallo Mine.

Earnings from Operations

Earnings from operations for Q2 2015 were $13.4 million, compared to $6.6 million for Q2 2014. The increase was attributable to an increase in gold and silver sales, resulting from increased production at the El Gallo Mine.

Cash Flow

Net cash flow generated from operations was $6 million or $0.02 per share for Q2 2015, compared to net cash used by operations of $7 million or $0.02 in Q2 2014. The higher cash flow is reflective of an increased number of ounces sold during the quarter. Our El Gallo Minecontributed $37.7 million in gold and silver sales compared to $22.8 million in Q2 2014.

Net Loss

Consolidated net loss was $14.1 million or $0.05 per share for Q2 2015, compared to a net loss of$104.0 million or $0.35 per share for Q2 2014. The net loss was attributable to an impairment of$28.5 million on certain mineral properties in Nevada which we decided to drop. After related deferred income tax recoveries the after-tax impairment was $18.5 million.

Adjusted Net Income

Adjusted net income for Q2 2015, which removes the impact of impairment of mineral properties, foreign exchange fluctuations and income tax recoveries, was $1.8 million or $0.01 per share. This compares to an adjusted net loss of $8.6 million or $0.03 per share in Q2 2014.

Ounces Sold

Gold equivalent ounces sold in Q2 2015 totaled 36,016 ounces, which includes 22,439 gold equivalent ounces attributable to us from our 49% interest in the San José Mine, and 13,577 gold equivalent ounces from the El Gallo Mine.

Average Realized Prices

The average realized price of gold and silver sold during Q2 was $1,172 and $15.34 per ounce respectively.

Production and Cost Guidance

We maintain our 2015 production guidance of 96,500 gold ounces and 3.1 million silver ounces, at a cash cost and AISC of $725 and $1,125 per gold equivalent ounce, respectively.

Treasury

We ended the quarter with $28.9 million in cash, cash equivalents, and precious metals; and a$5.8 million outstanding debt against our Mexican IVA (local VAT tax) receivable, which is drawn in Mexican Pesos. This short term debt will be retired in due course as and when we receive our IVA refunds during the year.

Distribution

As a result of improving operational performance and growing cash reserves, the Company started an annual distribution to shareholders of $0.01 per share. The distribution will be paid on a semi-annual basis, with the first installment of $0.005 payable on August 17th, 2015 to shareholders of record on July 31st, 2015. Our distribution is generally not taxable for residents ofthe United States and Canada because it is considered a return of capital. You are advised to speak to a financial professional should you have any questions or concerns about taxation.

El Gallo Mine, Mexico (100%)

The El Gallo Mine continues to outperform, having exceeded guidance in Q1 by 17% and Q2 by 15% as a result of higher grades and improved process efficiencies. Production in Q3 has so far been above expectations.

Our budget for sustaining capital and capital expenditures for 2015 is $3.2 million, including an estimated $1.4 million to be spent in the expansion of our leach pads, and $1.3 million for other operational improvement projects. In the six months ended June 30th, 2015 we spent $0.4 millionon capital expenditures.

The 2015 exploration budget for Mexico is $4.7 million. In the six months ended June 30th, 2015 approximately $2.9 million was spent on exploration.

San José Mine, Argentina (49%)

Production in the quarter was 21,839 gold equivalent ounces, compared to 20,576 gold equivalent ounces in Q2 2014. Total cash costs in Q2 was $933 per gold equivalent ounce compared to$938 in Q2 2014. Costs have remained level during the past year despite difficult economic conditions in Argentine, which is a result of prudent management by our partner. The San José Mine remains on target to produce 46,500 ounces of gold and 3.1 million ounces of silver in 2015. This equates to 87,800 gold equivalent ounces at cash costs of $825 and AISC of $1,225 per gold equivalent ounce.

During Q2 2015, McEwen Mining received $0.5 million in dividends from its 49% interest in the San José Mine.

Gold Bar Development Project, Nevada, U.S. (100%)

We continue to advance the Gold Bar permitting process for construction and production of the open-pit heap leach project. Final permit approval is expected in the second half of 2016.

A drill program consisting of 38 in-fill holes was completed during the quarter at cost of $0.5 million. The focus of the program was to increase the mineral resource confidence by converting inferred gold ounces to the measured and indicated categories. In addition to upgrading our confidence, several holes returned significant results including 4.65 gpt gold over 41.1m and2.2 gpt gold over 52m. An updated resource estimate and feasibility study which will incorporate the results of the drill program is scheduled to be released in the third quarter.

Major optimizations considered in the new feasibility study will include: 1) a new resource estimate, 2) a revised mine plan that reduces pre-development capital and accesses ore earlier, 3) removal of 2-stage crushing in favor of a run-of-mine heap leach, 4) electrical power alternatives, and 5) an owner operated vs. contractor trade off analysis.

El Gallo 2 Development Project, Mexico (100%)

Work to update the feasibility study for El Gallo 2 is ongoing, however, due to the recent decline in the silver price more capital cost savings and processing improvements are necessary. The scope of the changes currently being considered will require additional work on certain aspects of the project, and will delay the release of a new feasibility study into 2016. Efforts to optimize the metallurgical recoveries have so far been successful, with both higher and more rapid silver recoveries demonstrated in lab tests.

Los Azules Project, Argentina (100%)

For 2015, we have budgeted $0.7 million for Los Azules. While no significant exploration work or drilling program is expected, we will continue to advance the project with baseline environmental studies. For the three and six months ended June 30th, 2015, expenditures on the Los Azules project totaled $0.2 million and $0.3 million respectively.

The Company's intention is to monetize Los Azules and to use proceeds to advance its development projects.

TECHNICAL INFORMATION

The technical contents of this news release has been reviewed and approved by Nathan M. Stubina, Ph.D., P.Eng., FCIM, Managing Director and a Qualified Person as defined by Canadian Securities Administrator National Instrument 43-101 "Standards of Disclosure for Mineral Projects".

RELIABILITY OF INFORMATION REGARDING THE SAN JOSÉ MINE

Minera Santa Cruz S.A., the owner of the San José Mine, is responsible for and has supplied to the Company all reported results from the San José 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.

CAUTIONARY NOTE TO US INVESTORS REGARDING RESOURCE ESTIMATION

McEwen Mining 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 generally permitted in reports filed with the SEC. Under NI 43-101, McEwen Mining reports measured, indicated and inferred resources, measurements, which 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. 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.

CAUTIONARY NOTE REGARDING NON-GAAP MEASURES

In this report, we have provided information prepared or calculated according to 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.

(1) Total Cash Costs and All-in Sustaining Costs

Total cash costs consist of mining, processing, on-site general and administrative costs, community and permitting costs related to current explorations, royalty costs, refining and treatment charges (for both doré and concentrate products), sales costs, export taxes and operational stripping costs. All-in sustaining cash costs consist of total cash costs (as described above), plus environmental rehabilitation costs, amortization of the asset retirement costs related to operating sites, sustaining exploration and development costs, and sustaining capital expenditures. In order to arrive at our consolidated all-in sustaining costs, we also include corporate general and administrative expenses. Depreciation is excluded from both total cash costs and all-in sustaining cash costs. For both total cash costs and all-in sustaining costs we include our attributable share of total cash costs from operations where we hold less than a 100% economic share in the production, such as MSC where we hold a 49% interest. Total cash cost and all-in sustaining cash cost per ounce sold are calculated on a co-product basis by dividing the respective proportionate share of the total cash costs and all-in sustaining cash costs for the period attributable to each metal by the ounces of each respective metal sold. We use and report these measures to provide additional information regarding operational efficiencies both on a consolidated and an individual mine basis, and believe these measures provide investors and analysts with useful information about our underlying costs of operations. 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, 2015.

(2) Adjusted net income (loss)

Adjusted net income (loss) excludes the following items from net income (loss): impairment charges (including inventory and IVA taxes receivable write-downs, and impairments of long-lived assets), and the related income tax recovery; foreign currency gains and losses, including the impact of foreign currency fluctuations on our deferred income tax liabilities denominated in Argentine peso; and other non-recurring items, if applicable. We use and report this measure because we believe it provides investors and analysts with a useful measure of the underlying operating performance of our core mining business. A reconciliation to the nearest U.S. GAAP measure is provided in McEwen Mining's Quarterly Report on Form 10-Q for the quarter endedJune 30, 2015.

(3) Earnings from mining operations

The term Earnings from Mining Operations used in this report is a non-GAAP financial measure. We use and report this measure because we believe it provides investors and analysts with a useful measure of the underlying earnings from our mining operations.

We define Earnings from Mining Operations as Gold and Silver Revenues from our El Gallo 1 Mine and our 49% attributable share of the San José Mine's Net Sales, less their respective Production Costs Applicable to Sales. To the extent that Production Costs Applicable to Sales may include depreciation and amortization expense related to the fair value increments on historical business acquisitions (fair value paid in excess of the carrying value of the underlying assets and liabilities assumed on the date of acquisition), we deduct this expense in order to arrive at Production Costs Applicable to Sales that only include depreciation and amortization expense incurred at the mine-site level. The San José Mine Net Sales and Production Costs Applicable to Sales are presented, on a 100% basis, in Note 5 of McEwen Mining's Quarterly Report on Form 10-Q for the quarter ended June 30, 2015.

(4) Average realized prices

The term average realized price per ounce used in this report is also a non-GAAP financial measure. We report this measure to better understand the price realized in each reporting period for gold and silver. Average realized price is calculated as sales of gold and silver (excluding commercial deductions) over the number of ounces sold in the period.
