Treasury

As of March 31 , 2017 we had $55.1 million in cash, investments and precious metals valued at the spot prices; and no debt. This

compares to liquid assets of $58.8 million and no debt at the end of Q4 2016.

Ounces Produced

Consolidated gold equivalent production in Q1 2017 totaled 29,733 ounces, which consists of 9,808 gold equivalent ounces from

the El Gallo mine, and 19,925 gold equivalent ounces attributable to us from our 49% interest in the San José mine.

Production Costs

For our El Gallo mine in Q1 2017, total cash costs and all-in sustaining cash costs were $564 and $668 per gold equivalent ounce,

respectively. For our San José mine in Q1 2017, total cash costs and all-in sustaining costs were $915 and $1,165 per gold

equivalent ounce, respectively.

Earnings from Mining Operations

In Q1 2017, earnings from mining operations from our El Gallo mine were $8.2 million, compared to $12.4 million in the same

period in 2016; and earning from mining operations from our 49% interest in the San José mine were $5.7 million, compared to

$7.0 million in the same period in 2016.

Net Income/ Loss

Our consolidated net loss for Q1 2017 was $3.0 million, or $0.01 per share, compared to a net income of $13.0 million, or $0.04

per share for the same period in 2016. The net loss was mainly due to a $6.4 million decrease in sales of gold and silver by our El

Gallo mine; coupled with a $6.7 million increase in exploration costs, mostly related to the drilling campaign performed at the Los

Azules project, compared to the same period during 2016.

Cash Flow

Net cash used in operations was $6.9 million in Q1 2017, compared to net cash provided by operations of $14.7 million for the

same period in 2016. In Q1 2017, our El Gallo mine contributed $14.8 million in gold and silver sales to operating cash flow,

compared to $20.3 million in the same period in 2016. The significant change in cash flow quarter over quarter related mainly to a

reduction in the number of ounces sold from the El Gallo mine, coupled with lower VAT collection from our Mexican operations

and the increase in metals inventory. In Q1, 2017 our 49% interest in the San José mine contributed $2.5 million in dividends to

operating cash flows, compared to $2.6 million in the same period in 2016.

Average Realized Prices

Average realized prices in Q1 2017 were $1,220 per ounce of gold sold, and $17.54 per ounce of silver sold at our El Gallo mine;

and $1,253 per ounce of gold sold and $18.18 per ounce of silver sold for the San Jose mine. In comparison, the average realized

prices in the same period in 2016 were $1,171 per ounce of gold sold, and $14.64 per ounce of silver sold at El Gallo mine; and

$1,257 per ounce of gold sold and $15.29 per ounce of silver sold for the San Jose mine.

Return of Capital

The fourth return of capital installment of 1/2¢ per common share was paid on February 14, 2017. To date a total of $6 million has

been returned to share owners.

Production Guidance

Production for 2017 is expected to be 49,700 ounces of gold and 24,000 ounces of silver from the El Gallo mine, and 50,000

ounces of gold and 3,300,000 ounces of silver from the San José mine. Using a silver to gold ratio of 75:1 for the year 2017, this

represents projected consolidated production of 144,000 gold equivalent ounces.

Cost Guidance

For 2017, total cash costs and all-in sustaining costs at the El Gallo mine are forecast to be $760 and $900 per gold equivalent

ounce, respectively; and total cash costs and all-in

sustaining costs at the San José mine are forecast at $780 and $990 per gold

equivalent ounce, respectively. Our guidance is based on an average silver to gold ratio of 75:1.

Strategic Acquisition of Timmins Projects

On April 26, 2017 the acquisition of Lexam VG Gold Inc. was completed. This represents a strategic acquisition of former producing

mine properties (brownfield sites) in the heart of the world class Timmins gold mining district in Canada. Situated within a mile radius

around our newly acquired assets are large former and currently producing mines with past gold production in excess of 55 million

ounces.

Our Timmins brownfield sites have good access to roads, power and nearby experienced workforce. Some of the properties have mine

infrastructure in place, such as existing shafts, ramps and pits from previous mining activities. This should reduce future development

costs. The current NI 43-101 resources are: 1.5 million gold ounces in the Measured and Indicated categories, and 1 million gold

ounces in the Inferred category. For 2017, we have budgeted $3.0 million for exploration and development related activities in

Timmins. Of particular interest are the high grade drill intercepts of past exploration programs.

Operations & Projects

Mexico

El Gallo Gold Mine (100%)

Production at the El Gallo Gold mine for Q1 2017 declined quarter over quarter by 51% to 9,808 gold equivalent ounces, due to

slower than planned access to higher grade ore. However, the mine is on track to meet our 2017 production guidance of 50,000 gold

equivalent ounces. The El Gallo gold mine is a mature operation that has mined and depleted most of its oxide resources. While ore

grades processed during Q1 2017 averaged 1.28 gpt gold, compared to 3.62 gpt gold in Q1 2016, Optimization

Exploration efforts are now focused on defining resources in sulfide and transitional mineralization that could extend the asset life,

and, as such, we have budgeted a total of $1.8 million for exploration activities at the El Gallo mine, and $2.0 million for sustaining

capital expenditures for 2017.

El Gallo Silver Project (100%)

During Q1 2017, work continued on the El Gallo silver project to identify opportunities to reduce the initial capital investment

required to start the project and reduce its projected operating cost. Our 2017 budget for El Gallo Silver is approximately $7.8 million,

comprised of $4.8 million for exploration and $3.0 million for development.

Argentina

San José Mine (49%)

Gold and silver production attributable to us from our 49% interest in the San José mine for Q1 2017 increased quarter over quarter by

12% to 19,925 gold equivalent ounces. During Q1 2017 we received $2.5 million in dividends from the San José mine.

For the remainder of 2017 we expect to continue to receive dividends from our 49% interest in San José. We anticipate receiving

dividends totaling $10.0 million or more, with the final amount being determined by the mine’s profitability, treasury position, and

decisions on capital and exploration investments.

Los Azules Project (100%)

During Q1 2017 we spent $6.3 million at the Los Azules project on a combination of infill and exploration drilling, significant

advances were made in determining the best logistics, power and infrastructure options and further economic and engineering

modeling of the production. Results from the drilling campaign are expected to be finalized during the second half of 2017.

Gold Bar Project, Nevada, U.S. (100%) — Advancing Towards Construction

the US Bureau of Land Management (“BLM”) published the Draft Environmental Impact Statement in the Federal Register on

March 3 , 2017 and subsequently closed the 45-day public comment period. Comments received during the public comment period

are now being addressed and will be incorporated in the final Environmental Impact Statement.

During Q1 2017 we spent $0.9 million on various requirements to complete our permitting process for Gold Bar. We also expect to

spend an additional $1.1 million in permitting activities during the remainder of 2017.

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. 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 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 the nearest U.S. GAAP measure is provided in McEwen

Mining’s Quarterly Report on Form 10-Q for the quarter ended March 31, 2017.

(2) 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 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 March 31, 2017.

(3) 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 (net of deduction units). A reconciliation to the

most directly comparable U.S. GAAP measure, Sales of Gold and Silver, is provided in McEwen Mining’s Quarterly Report on

Form

10-Q for the quarter ended March 31, 2017.

(4) Cash, investments and precious metals

The term cash, investments and precious metals used in this report is a non-GAAP financial measure. We report this measure to better

understand our liquidity in each reporting period. Cash, investments and precious metals is calculated as the sum of cash, investments

and ounces of doré held in inventory, valued at the London P.M. Fix spot price at the corresponding period. A reconciliation to the

most directly comparable U.S. GAAP measure, Sales of Gold and Silver, is provided in McEwen Mining’s Quarterly Report on

Form 10-Q for the quarter ended March 31, 2017.
