	Response Dated January 23, 2017
	File No. 001-33190

Dear Mr. Arakawa:

We refer to your correspondence dated January 31, 2017, addressed to Andrew Elinesky, Chief Financial Officer of McEwen Mining Inc. (“McEwen Mining”, the “Company” or “we”), relating to the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 (the “2015 Form 10-K”). This letter contains the responses to the comments contained in your January 31, 2017 letter.

The Company’s responses are as follows:

Form 10-K for the Fiscal Year ended December 31, 2015

Management’s Discussion and Analysis of Financial Condition and Results of Operations

Non-GAAP Financial Performance Measures, page 61 through 66

Comment No. 1

We have reviewed your response and proposed disclosure to comment 1 noting you do not believe you have substituted an individually tailored accounting principle for the one in GAAP in your non-GAAP presentation of earnings from mining operations, total cash costs, all-in sustaining costs, all-in costs, and average realized prices. We note from your response and proposed disclosure that you are merely multiplying each individual line item on the financial statements of Minera Santa Cruz by your ownership percentage of 49%.  Please note that under the equity method of accounting you own an interest in the investee as a whole and do not have a proportionate legal interest in each financial statement line item.  Since you account for your interest in the Minera Santa Cruz mine using the equity method, inclusion of a proportionate economic ownership in the non-GAAP measures does not appear to be consistent with the guidance in Question 100.04 of the updated non-GAAP Compliance and Disclosure Interpretations issued on May 17, 2016. Please revise your non-GAAP disclosures accordingly.

Response:

Upon reviewing the staff’s recent comments in conjunction with our non-GAAP disclosure in the 2015 Form 10-K, and having further conversations with the staff, we identified certain modifications which we propose to incorporate prospectively, commencing with our 2016 Form 10-K. Specifically, we intend to cease consolidating the proportionate economic ownership of Minera Santa Cruz (“MSC”), in our non-GAAP measures and to separate the presentation of non-GAAP measures relating to our majority owned and controlled mine (El Gallo 1 Mine) from results of our minority owned mine (Sane José Mine, through our interest in MSC). In addition, our all-in sustaining costs will exclude the allocation of corporate general and administrative costs, and as such, we will revise our definition of the calculation of all-in sustaining costs to explain this removal to provide clarity in our report.

Consistent with our response dated January 23, we also propose to include additional disclosure in the narrative preceding the non-GAAP measures to alert the reader that we do not control the interest in, or operations of, MSC and the presentation of any assets, liabilities, revenues or expenses of MSC do not represent our legal claim to those items.

Please refer to the proposed prospective disclosure, using our 2015 Form 10-K non-GAAP performance measures for illustrative purposes, attached to this letter as follows:

·Appendix A: earnings from mining operations,

·Appendix B: total cash cost,

·Appendix C: all-in sustaining costs, and

·Appendix D: average realized prices.

Within each illustration, we excluded disclosure of consolidated results and consolidated totals.

Additionally, to avoid the appearance of providing individually tailored accounting principles as substitutions for GAAP measures, we will no longer provide the all-in costs metric as a whole because on a non-consolidated basis, the metric does not provide an appropriate comparison to our industry peer group.

In light of our consideration and the proposed revisions described herein, we also propose to eliminate the enhanced note disclosure, describing our equity investment in MSC, initially outlined in Appendix A of our January 23, 2017 response.

In speaking with the staff, we understand that it has allowed a transition period for implementing the changes to non-GAAP disclosure as a result of, among other items, the Compliance Disclosure Interpretations issued on May 17, 2016. We appreciate this opportunity and propose to take advantage of it.  In this regard, we intend to present consolidated earnings from mine operations, total cash costs, all-in sustaining costs, all-in costs, and average realized prices in our 2016 earnings release and related disclosure (but not in the 2016 Form 10-K). Furthermore, we intend to provide our future guidance of non-GAAP measures in line with the proposed disclosure to our 10-K as discussed above.

With the forgoing undertaking and explanation, we believe that we have responded to all the comments in the staff’s letter. Should you have any additional questions or comments, please contact the undersigned at 647-258-0395.

Sincerely,

MCEWEN MINING INC.
