Sierra Metals announces favourable ruling in Polo y Ron Minerals litigation

VANCOUVER, Aug. 1, 2014 /CNW/ - Sierra Metals Inc. (TSX:SMT)(BVL:SMT) ("Sierra Metals" or the "Company") is pleased to report a positive development in the Polo y Ron Minerals legal process.  A Federal Court in the State of Chihuahua has ordered that Sierra is entitled to receive proper notice of the adverse resolution previously issued by the State Court of Chihuahua as disclosed in the Company's press release on March 16, 2013.

This is an important procedural step that allows the Company to proceed with its appeal (writ of "amparo") of the State Court's previous resolution. The adverse resolution has been temporarily suspended since March 2013, which suspension will remain in place pending the writ of amparo.  The amparo will be heard in Federal Court and will challenge the State Court's ruling.  The Federal Court's verdict in the amparo will be final and non-appealable.

The Company continues to vigorously defend its position by applying the proper legal resources necessary to defend its position.  Sierra continues to believe that the original claim is without merit.

In October 2009, Polo y Ron Minerals, S.A. de C.V. ("P&R") sued the Company (under the name Dia Bras Exploration Inc., the Company's previous name) and one of its subsidiaries, Dia Bras Mexicana, S.A. de C.V. P&R claimed damages for the cancelation of an option agreement (the "Option Agreement") regarding the San Jose properties in Chihuahua, Mexico (the "San Jose Properties").

The Company believes that it has complied with all of its obligations pertaining to the Option Agreement.

In October 2011, the 8th Civil Court of the Judicial District of Morelos in Chihuahua issued a resolution that absolved the Company from the claims brought against it by P&R on the basis that P&R did not provide evidence to support any of its claims. P&R appealed this resolution to the State Court, which overruled the previous resolution and ordered the Company to: (i) transfer to P&R 17 mining concessions from the Company's Bolivar project, including the mining concessions where mine operations are located; and (ii) pay US$422,674 to P&R.

The San Jose Properties are not located in any areas where Dia Bras Mexicana, S.A. de C.V currently operates, nor are these properties included in any resource estimates of the Company.
