Dear Ms. Jenkins:

On behalf of Southern Copper Corporation (the “Company”), I, Oscar Gonzalez Rocha, the Company’s President and Chief Executive Officer, submit our response to your letter dated July 26, 2012, relating to the above-referenced filing.

To assist in the Staff’s review of the Company’s responses, we have preceded our response with the text (in bold type) of the comment as stated in your letter.

Property Book Value, page 7

2.In conjunction with the capitalization of costs associated with your Tia Maria development project, mineral reserves should be disclosed.  Please include this disclosure in your filing or tell us why you are unable to do so.  In this regard we reference paragraph (c) of the Instructions to 102 of Regulation S-K.

We appreciate the Commission’s comment. As we reported to the Commision in our prior response, at December  31, 2011, the total amount spent on the Tia Maria project was $434.1 million which was recorded as construction in progress in our consolidated balance sheet; see Note 6, Property.   However, we did not disclose the proven and probable mineral reserves of the Tia Maria project because it was suspended by governmental action in April 2011.

As we disclosed in our prior response, we are currently in the process of preparing a new Environmental Impact Assessment study in order to obtain the necessary environmental approvals and permits, which will allow us to restart the project.  Once the approvals are obtained, we will disclose the proven and probable mineral reserves of the Tia Maria project in future Form 10-K filings, as required.  At present, no assurances can be given as to the specific timing of the approvals.
