MCEWEN MINING REPORTS INITIAL RESOURCE AND

HIGH GRADE DRILL INTERSECTIONS AT STOCK PROPERTY

TORONTO, Sept. 6, 2018 - McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) reports an initial Inferred resource estimate for the Stock East Deposit, and highly encouraging early stage exploration results from targets located on the Stock Property, part of the Black Fox Complex near Timmins, Ontario, Canada.

Highlights include:

· The initial Stock East Deposit Inferred resource estimate is 114,000 gold ounces at a grade of 2.54 g/t (combined open pit and underground), which is part of a 2 km long mineralized trend that also hosts the past-producing underground Stock Mine (historical production of 137,000 gold ounces at a grade 5.5 g/t, and no current resource estimate).

· Stock East drilling intersected 25.16 g/t gold over 2.09 m.

· Stock Mine drilling intersected 22.15 g/t gold over 1.39 m and 7.01 g/t gold over 2.98 m on the depth extension of the mine.

Drilling started in February at Stock East, a target that was unexplored for over 20 years. The encouraging results from that campaign prompted us to extend drilling activities over a 2 km long trend that includes the Stock Mine, Gap and Stock East targets. Positive drill results include narrow higher grade intersections, and also wider and lower grade intersections that may support the potential for open pit mining,” stated Sylvain Guerard, Senior Vice-President Exploration.

Stock East

The Stock Property covers a 6.5 km section of the Destor-Porcupine fault. The Stock East Zone is located 700 m east of the former Stock Mine and current mill facilities (see Figure 1). Drilling to date has outlined a thick sequence of gold-bearing altered mafic volcanic rocks believed to represent the eastern strike extension of the former Stock Mine.

An initial drilling program beginning in February 2018 (Phase 1) returned encouraging intersections of gold mineralization, which were previously reported in press releases dated April 30 and July 25, 2018. A follow-up drilling program began in June 2018 (Phase 2) and is still in progress.

Stock East highlights are listed in the table below:

Drilling has outlined an open pit and underground Inferred resource estimate for the Stock East Deposit totaling 114,000 gold ounces at a grade of 2.54 g/t. Stock East has a strike length of approximately 400 m and extends vertically from surface to a depth of at least 350 m and is open in all directions. An infill drill program is ongoing with the objective of upgrading the resource to the Indicated category later in 2018.

Stock Mine and Gap Target

In addition to drilling the Stock East Zone, the current Phase 2 program is also testing two other areas at the Stock Mine and the Gap Zone, which have had very little previous drilling.

Four holes have been drilled underneath the historical mine workings testing for the extension of the Stock Mine mineralization at depths from approximately 320 to 700 m below surface. In addition, 11 holes have been drilled along a 400 m trend east of the Stock Mine, testing continuity in sparsely drilled areas located along the main structure (Gap Zone).

Gold mineralization has been intersected in a variety of lithological settings including altered feldspar porphyry intrusions, altered mafic volcanic rocks and fuschite-altered ultramafic rocks. The zones include wide intervals of lower-grade gold mineralization (grades from 0.8 to 1.25 g/t gold over widths of 18 to 30 m) and narrow intervals of higher-grade gold mineralization (grades of 5 to 22 g/t gold over widths of 1 to 4 m).

The results below support the potential to extend the mineralization down plunge from the Stock Mine, and for shallow mineralization along the 2 km long trend that extends from the hanging wall of the Stock Mine to the Stock East Zone. Follow-up drilling is ongoing.

Stock Mine highlights are listed in the table below:

Stock East Resource

The Stock East Deposit Inferred resource estimate, effective September 5, 2018, is comprised of two components; an open pit constrained Inferred resource of 40,000 gold ounces, and an underground resource of 73,000 gold ounces. Details are as follows:

Classification |  | Cut-off Grade Gold (g/t ) |  | Quantity (‘000 t) |  | Gold Grade (g/t) |  | Contianed Gold (oz) |
Open Pit Inferred |  | 0.25 |  | 798 |  | 1.58 |  | 40,000 |
Underground Inferred |  | 2.40 |  | 591 |  | 3.85 |  | 73,000 |
Total |  |  |  | 1,389 |  | 2.54 |  | 114,000 |

Stock East Mineral Resource Estimate Notes:

· The Mineral Resource Statement complies with the standards for reporting mineral resources as set out under CIM guidelines;

· Resources are presented undiluted and in-situ and are considered to have reasonable prospects for eventual economic extraction;

· Mineral resources are not mineral reserves and do not have demonstrated economic viability; all figures are rounded to reflect the relative accuracy of the estimate;

· Open Pit constrained resources are reported at a cut-off grade of 0.25 g/t Au; underground resources are reported at a cut-off grade of 2.4 g/t Au.

· Drill hole intervals were composited to 1 m lengths within mineralized domains;

· After statistical analysis, grade capping was not used for the composite data; however a high grade restricted search was utilised;

· A density value of 2.60 t/m3 was applied to all lithologies. Additional density measurements on the various lithologies and host rocks to be undertaken;

· Estimation parameters were determined by variography; all zones were interpolated using Ordinary Kriging (OK);

· Block dimensions were 6x6x6 m with sub-celling down to 1 m blocks;

McEwen Mining is not aware of any known environmental, permitting, legal, title-related, taxation, socio-political or marketing issues that could materially affect the mineral resource estimate.

The resource estimate is the result of detailed logging and assaying of 69 surface drill holes. In addition to the recent drilling and assay results from 20 drillholes completed by McEwen between February and August 2018, data from a further 47 historic drillholes from the 1990s was used. A re-sampling program of the historic holes have shown that the re-assays are comparable with the historical grades. Statistical analysis of the data (including a 2 sample t-test) indicate that the difference between the original grades and re-assays is close to zero. However, most of the re-sampling was completed on the core from the low-grade intersections of the historical holes, as the core from higher-grade historical intersections was mostly unavailable for re-sampling.

TECHNICAL INFORMATION

All intercept widths are true widths unless otherwise specified.

All exploration drill core samples at the Black Fox Complex were submitted as 1/2 core. Analyses reported herein were performed by the independent laboratories: ALS Laboratories, which is ISO 9001/IEC17025 certified, Activation Labs, which is ISO 9001/IEC17025 certified, and SGS Canada Laboratories, which is ISO9001/IEC17025 certified. Samples from definition and select delineation drilling, and development sampling completed within the Black Fox mine are assayed at McEwen’s onsite laboratory. McEwen’s quality control program includes systematic insertion of blanks, standard reference material and duplicates to ensure laboratory accuracy.

To determine the lengths of significant mineralized intervals, the following composite criteria was established: a minimum reportable interval length of 3 m was determined by establishing a cut-off grade of 3 g/t Au for underground (0.5 g/t Au for near surface). A consecutive maximum length of 3 m of internal waste, including sub cut-off grade material, is allowed and incorporated into the reported composites. Where an interval of less than 3 m is considered, if the grade x length calculation is greater than 9 (3 for surface), it may be reported. There is no top cutting or capping of assays.
