Exhibit 99.1

MCEWEN MINING REPORTS Q1 2018 PRODUCTION RESULTS

TORONTO, Apr 16, 2018 - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) reports consolidated production for Q1 2018 of

35,069 gold ounces and 695,651 silver ounces, or 44,344 gold equivalent ounces(1)(“GEOs”), using a 75:1 gold to silver ratio.

Consolidated Production Summary

Highlights of the first quarter from our three producing mines and our newest mine in Nevada, which is under construction, are as

follows:

Gold Bar Mine, USA (100%)

Construction activities at Gold Bar focused on finishing civil works related to the heap leach pad, ponds and site infrastructure, in

preparation for major equipment and material deliveries in the second quarter. Construction is advancing on schedule for completion

by the end of 2018. During the first three years of operation beginning in 2019 Gold Bar is projected to produce 55,000, 74,000 and

68,000 ounces of gold respectively.

Black Fox Mine, Canada (100%)

Black Fox produced 12,078 GEOs, in line with our full year production guidance for 2018 of 48,000 GEOs. A $12 million exploration

program is ongoing across the Black Fox Complex, drilling results and other developments will be released quarterly, with the next

update anticipated by the end of April.

A new technical report and resource/reserve estimates for the Black Fox Complex was published on April 6, 2018. The complete

report, with an effective date of October 31, 2017, is available on the Company’s website and on www.sedar.com. For comparative

purposes the previous resource/reserve estimates by the former property owner had an effective date of December 31, 2016. The new

mineral resource estimate for the Black Fox Mine resulted in a 40% increase in gold resource in the Indicated category to 538,000

ounces, and a decrease of 2% in the Inferred category to 44,000 ounces (see Table i). The overall increase is mainly attributable to

improvements in methodology used to constrain high and low-grade domains within lithological and alteration envelopes. This

significantly reduced internal dilution that previously resulted in the exclusion of potential resource. Additionally, capping grades and

variography parameters were reviewed and tailored to each domain.

The new mineral reserve estimate for the Black Fox Mine resulted in a 2% increase in Proven and Probable gold reserves to 113,000

ounces (see Table ii).

Resource estimates for the Froome and Grey Fox deposits were also updated. The new Froome resource estimate is in line with the

previous estimate. At Grey Fox, the updated resource considered a potential underground mining scenario (previously open pit and

underground) and was calculated using additional drill hole data, updated geological and structural interpretations and tighter controls

on the estimation process. Comparing underground resources only, gold resource in the Indicated category increased by 44% to

465,000 ounces, and the Inferred category decreased by 32% to 100,000 ounces.

Q1 ‘18 Q4 ‘1 7 Q3 ‘17 Q2 ‘17 Q1 ‘17

Gold ounces 35,069 48,609 19,051 22,191 20,096

Silver ounces 695,651 926,739 749,749 779,48 7 722,767

GEOs 44,344 60,965 29,047 32,584 29,733

El Gallo Mine, Mexico (100%)

El Gallo produced 12,217 GEOs, in line with our budget and full year production guidance for 2018 of 32,000 GEOs. Mining from the

existing open pits will cease in Q2, while heap leaching activities are expected continue until 2020, or as long as it remains

economical to do so. Operating expenses will diminish significantly in Q2, while gold production will decline more gradually,

resulting in an overall reduction in cost per ounce produced for the balance of 2018.

San José Mine, Argentina (49%)

Our attributable production from San José was 10,822 gold ounces and 692,052 silver ounces, for a total of 20,049 GEOs. Production

at San José in the first quarter is typically lower than other quarters due to regularly scheduled maintenance, however the mine is on-

track to achieve our full year guidance for 2018 of 91,000 GEOs. We received approximately $5 million in dividends from our interest

in San José during Q1, and with spot gold and silver prices significantly above budget, we expect to continue to receive dividends in

each of the subsequent quarters.

First Quarter Financial Results

Operating costs for the quarter ended March 31, 2018 will be released with our 10-Q Quarterly Financial Statements in early May. As

of April 6, 2018 we are debt-free with liquid assets of approximately $52 million.

Table i: Mineral Resource Statement, Black Fox Complex, SRK Consulting (Canada) Inc., October 31, 2017

x Mineral resources are not mineral reserves and do not have demonstrated economic viability. All figures rounded to reflect the

relative accuracy of the estimates. Composites were capped where appropriate. Mineral resources reported at variable cut-off

grades as indicated, assuming an underground extraction scenario, a gold price of US$1,500/oz, C$:US$ exchange rate of 1.25;

and metallurgical gold recoveries of 96 percent for Black Fox, 90 percent for Froome and 80 percent for Grey Fox.

Table ii: Mineral Reserve Statement, Black Fox Mine, SRK Consulting (Canada) Inc., October 31, 2017

x Mineral reserves are included in the mineral resources. All figures have been rounded to reflect the relative accuracy of the

estimate. Mineral reserves are based on a cut-off value of 3.72 g/t gold (4.28 g/t including 15% dilution) assuming a gold price of

US$1,250/oz, a C$:US$ exchange rate of 1.25:1:00, milling recoveries of 96%, royalty of 4.55%, and operating cost of C$171/t.

Mineral reserves are stated at a mill feed reference point and include for diluting materials and mining losses.
