Fresnillo announces investment in Sinda Ltd.

Fresnillo plc ("Fresnillo" or "the Company") is pleased to announce today that it has entered into an agreement to acquire shares of common stock (the "Common Shares") of Sinda Ltd ("Sinda") pursuant to a private placement concurrent to Sinda's initial public offering (the "IPO") and NYSE listing in the United States (the "Concurrent Placement"). The purchase price per Common Share for the Concurrent Placement will be the same as the per share public offering price to be set forth on the cover page of the final prospectus relating to the IPO. Upon completion of the Concurrent Placement, Fresnillo will hold up to approximately 5.0% of the issued and outstanding of Common Shares of Sinda, on a non-diluted basis. The closing of the Concurrent Placement is conditioned on the completion of the IPO.

Sinda holds title to, or has exploration and exploitation rights on, five contiguous mining concessions covering a large-scale, high-grade, silver-gold greenfield discovery (the "Sinda Property" or the "Project"), adjacent to Fresnillo's advanced exploration project, located in the historic Guanajuato epithermal silver belt of Mexico. The Sinda Property is a large primary silver asset that has the potential to be a globally significant mining operation.

Fresnillo is acquiring the Common Shares to enhance its exposure to attractive geological silver districts, complementary to the Company's organic portfolio.

Closing of the Concurrent Placement is subject to customary closing conditions, including the closing of the IPO. In connection with the closing of the Private Placement, Fresnillo and Sinda will enter into an investor rights agreement providing, among other things, a standstill on customary terms and conditions and participation rights in favour of Fresnillo to maintain its pro-rata interest in Sinda on a non-diluted basis, provided Fresnillo maintains a certain ownership threshold in Sinda. In addition, Fresnillo has entered into a lock-up on customary terms with respect to the Common Shares purchased in the Concurrent Placement.

A registration statement on Form S-1 has been filed with the U.S. Securities and Exchange Commission ("SEC") relating to the shares to be offered in the IPO (the "IPO Shares") but has not yet become effective. The Common Shares, like the IPO Shares, will be listed on the NYSE, and will have the same rights and privileges and rank equally, share ratably, and be identical in all respects for all purposes as the IPO Shares, except that the Common Shares may not be offered and sold in the United States absent registration or an applicable exemption under the Securities Act. Sinda has agreed to file a registration statement promptly following the closing of the Concurrent Placement to permit the resale of the Common Shares in the United States. The Common Shares may not be sold nor may offers to buy be accepted until such registration statement becomes effective and the applicable lock-up periods have elapsed. Copies of the registration statement can be accessed through the SEC's website at www.sec.gov. This press release shall not constitute an offer to sell or a solicitation of an offer to buy the securities described herein, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state or jurisdiction.
