Sierra Metals Announces Share Repurchase Program

/THIS RELEASE IS NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR FOR DISSEMINATION IN THEUNITED STATES./

TORONTO, March 26, 2013 /CNW/ - Sierra Metals Inc. (TSXV: SMT) (BVL: SMT) ("Sierra Metals" or the "Company") is pleased to announce that its board of directors has approved a share repurchase program (the "Share Repurchase") pursuant to a normal course issuer bid in the open market through the facilities of the TSX Venture Exchange (the "TSXV"). Pursuant to the Share Repurchase, the Company proposes to repurchase for cancellation up to 7,886,873 common shares of the Company ("Common Shares"), which is the maximum number of Common Shares permitted to be purchased under the applicable policies of the TSXV. Haywood Securities Inc. will conduct the Share Repurchase on behalf of the Company.

In connection with its implementation of the Share Repurchase, Sierra Metals has obtained TSXV approval of its notice of intention to make a normal course issuer bid. The notice provides that Sierra Metals may purchase up to 7,886,873 Common Shares through the facilities of the TSXV during the 12-month period commencing on April 2, 2013 and ending on or before April 1, 2014.

In accordance with applicable TSXV policies, purchases made under the Share Repurchase will not, when aggregated with the total of all other purchases in the preceding 30 days, exceed 2% of the total issued and outstanding Common Shares at the time the purchases are made.

Sierra Metals will not make purchases of Common Shares other than open-market purchases. Any Common Share purchases made pursuant to the Share Repurchase will be at the prevailing market price at the time of the transaction, purchased in accordance with the policies of the TSXV and conducted by the appointed broker. All such Common Shares will be subsequently returned to treasury and cancelled by the Company.

Sierra Metals is adopting the Share Repurchase because it believes that its Common Shares have been trading in a price range which does not adequately reflect the underlying value of such securities in relation to the Company's business and future prospects. Accordingly, the reduction of its share capital that will result in the cancellation of any Common Shares acquired pursuant to the Share Repurchase will increase the proportionate interest of all remaining shareholders of the Company.
