  )</sup>
  
  (GEOs), at the average gold:silver price ratio for the quarter of
  
  79:1
  
  .

• For Q3 we spent
  
  $8.5 million
  
  on exploration and advanced projects, and are reporting a net loss of

  ^th
  
  we closed a private placement of flow-through common shares at a price of
  
  $1.65
  
  per share (representing a premium of
  
  21
  
  
  %
  
  over the share price) for gross proceeds of
  
  $10.4 million
  
  . These funds will be used exclusively for exploration activities in the Timmins region over the next 12 to 24 months.

“I am feeling much better this year than I did last year








at this time








because the bad news is behind us. Our operations are starting to turn around and improve; the financial pressure on our balance sheet has been alleviated; and our future growth is becoming much brighter. Investment capital is still in the early stages of moving into precious metals. There are a number of companies that are still being largely ignored but appear to have considerable upside potential. I believe McEwen Mining is one of those companies whose share price has a lot of catching up to do. Yes, last year was a nightmare and as shareholders we all suffered great frustration and confusion over the large loss of share value at a time when the price of gold was climbing ever higher. Our problems were many, some




were due to non-recurring events and others were operational. Our senior management at both head office and at our mines are focused on improving operating efficiencies and profit margins. Over the next several quarters we expect to deliver better operating results along with exploration news that we hope will start to close the price performance gap,”






commented Rob McEwen, Chairman & Chief Owner.

Operations Update

San José Mine


, Argentina


(49%


Interest)

Our attributable production from San José in Q3 was

8,600

gold ounces and

571,000

silver ounces, for a total of

15,900

GEOs

<sup>(

5)</sup>

. For Q3, total cash costs

<sup>(

)</sup>

and all-in sustaining costs (AISC)

<sup>(

)</sup>

were

$1,2


69

and

$1,


538

per GEO, respectively. During Q3, government-imposed COVID-19 travel restrictions limited the mobilization of personnel resulting in the mine continuing to operate below normal capacity.

Black Fox Mine


, Canada


(100%


Interest


)

Production from Black Fox was

5,8


00

GEOs in Q3, at cash costs and AISC of

$1,


581

and

$


1,644

per GEO, respectively. The operation is benefitting from the additional development work completed during Q2, which increased mining flexibility. We expect production to continue to trend higher during Q4, and mining from Black Fox to continue into Q1 2021, while we transition to mining the Froome deposit.

Black Fox – Underground Drilling

Delineation and definition drilling around the 240 m and 280 m level stoping areas in the central and west part of the Black Fox Mine has recently returned impressive grades including:

The positive results from these drill programs are being fast-tracked and evaluation for potential additions to mine planning inventory is ongoing.

A complete summary of new underground drilling results from Black Fox is available here:

Froome




– Development

Development of the underground access to the Froome deposit, located a half mile (800 m) west of the Black Fox mine, is on track, having advanced

47


%

by the end of the quarter. We plan to reach the main deposit in Q2 2021 and expect to achieve commercial production from Froome in Q4 2021. Froome offers several benefits compared to Black Fox such as a straighter, more efficient haulage route and wider, more consistent mineralization that is amenable to lower cost bulk mining methods. We are targeting an average annualized production rate of

40-45,000

GEOs from Froome over a period of approximately 2.5 years.

Fox Complex Expansion – Economic Study

We have engaged an independent engineering group to complete a Preliminary Economic Assessment (PEA) for the Fox Complex that includes Grey Fox, Black Fox, Stock and Lexam resources all utilizing our existing or potentially expanded central milling capacity. The PEA results are expected to be available in Q4 2020 and will suggest the optimal business case on which to complete a feasibility study in 2021. Combined, the Fox Complex deposits host nearly 3.0 million gold ounces in Measured and Indicated resources, and an additional 1.0 million gold ounces in Inferred resources

<sup>(

)</sup>

. The objective of the upcoming PEA is to develop a plan for the Fox Complex to grow to an annual production of

100-150,000

ounces of gold, at a cash cost of $800/oz and an all-in sustaining cost (AISC) of $1,100/oz, over a 10-year life, with production envisioned to start ramping up from 2022.

Grey Fox and Stock – 2020 Exploration

On September 10

^th

we completed a flow-through financing, which provides US$10 million for exploration activities in the Timmins region over the next 12 to 24 months. The initial focus is on two high-potential targets within 2 miles (3.2 km) of our existing operations at the Fox Complex:

Stock West

and

Whiskey Jack

. Both of these targets returned very encouraging results during the 2018-2019 drilling campaigns, and we are looking forward to continued exploration programs at these exciting discoveries, with the objective of defining additional resources.

Whiskey Jack




– Surface Drilling

Exploration drilling at Whiskey Jack continued to generate encouraging high grade results since our last update, from October 16

^th

, 2020 (for press release

Gold Bar Mine, USA (100% Interest)

Gold Bar produced

6,


8


00

GEOs in Q3 at cash costs and AISC of

$1,


585

and

$


1,769

per GEO, respectively. Operations at Gold Bar continued to ramp up during September, and savings from operational improvement initiatives are taking effect. For example, the combined average contractor and owner unit mining costs per ton of ore and waste moved decreased from $3.42/t in Q2 to $2.45/t in Q3, for a 28% decrease quarter on quarter. We expect costs to continue to trend lower in future quarters.

Evaluation of the resource estimate continued in Q3. We expect to have new resource and reserve estimates and an updated feasibility study in Q4.

El Gallo


Project, Mexico (100% Interest)

El Gallo produced

1,900



GEOs from residual leaching of the heap leach pad, compared to 1,900 GEOs in Q2 2020. Incremental residual leaching costs for Q3 were $3.1 million

<sup>(

)</sup>

, or

$1,


505

per GEO. An updated feasibility study for the Fenix Project is being finalized, and we expect to release the results in late Q4.

Production and Costs

Notes:

1. 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 definition of the non-GAAP measures see “NonGAAP 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 three months ended September 30, 2020 and for the year ended December 31, 2019 contained in our Form 10-Q and 10-K, respectively.
2. All amounts are reported in US dollars unless otherwise stated.
3. ‘Gold Equivalent Ounces’ are calculated based on a gold to silver price ratio of 75:1 for Q1 2019, 88:1 for Q2 2019, 87:1 for Q3 2019, 94:1 for Q1 2020,104:1 for Q2 2020 and 79:1 for Q3 2020.
4. Consolidated production guidance for Q4 2020 assumes an average gold:silver ratio of 80:1.
5. Represents the portion attributable to us from our 49% interest in the San José Mine.
6. Resources and Reserves for all the McEwen Mining projects can be found on our website at:
   
   https://www.mcewenmining.com/operations/reserves-and-resources/default.aspx
   
7. 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 key metrics for this operation.
8. Gold Bar commercial production was attained on May 23, 2019, with cash costs and AISC reported from Q2 2019. Pre-commercial production at Gold Bar during Q1 2019 was 2,030 GEOs.

Reliability of Information Regarding San José


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.

Technical Information


The technical contents of this news release has 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.”

Technical information pertaining to Fox Complex geology and exploration contained in this news release has been prepared under the supervision of Ken Tylee, P.Geo. Mr. Tylee is Qualified Person as defined by Canadian Securities Administrators National Instrument 43-101 “Standards of Disclosure for Mineral Projects.”

CAUTIONARY NOTE REGARDING NON-GAAP


FINANCIAL


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 doré 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 September 30, 2020.

Liquid


A


ssets


The term liquid assets used in this report is a nonGAAP financial measure. We report this measure to better understand our liquidity in each reporting period. Liquid assets are calculated as the sum of the Balance Sheet line items of cash and cash equivalents, restricted cash and investments, plus ounces of doré 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 September 30, 2020.

CAUTIONARY NOTE TO US INVESTORS REGARDING RESOURCE ESTIMATION


McEwen Mining Inc. is required to prepare reports under the Securities Exchange Act of 1934 and the Canadian Securities Administrators’ National Instrument 43101 “Standards of Disclosure for Mineral Projects” (“NI 43101”), under the Canadian securities laws because we are listed on the Toronto Stock Exchange (“TSX”) and therefore subject to Canadian securities laws. Standards under NI 43-101 are materially different than the standards generally permitted in reports filed with the United States (“U.S.”) Securities and Exchange Commission (“SEC”).

Under NI 43101, we report measured, indicated and inferred resources, which are measurements that 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 under Industry Guide 7. 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. Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. Therefore, U.S. investors are also cautioned not to assume that all or any part of inferred resources exist, or that they can be legally or economically mined.

Canadian regulations permit the disclosure of resources in terms of “contained ounces” provided that the tonnes and grade for each resource are also disclosed; however, the SEC only permits issuers to report “mineralized material” in tonnage and average grade without reference to contained ounces. Under U.S. regulations, the tonnage and average grade described herein would be characterized as mineralized material. We provide such disclosure about our properties to allow a means of comparing our projects to those of other companies in the mining industry, many of which are Canadian and report pursuant to NI 43101, and to comply with applicable disclosure requirements.
