| October 5, 2011 Orko Silver Corp. (TSX Venture Exchange: OK.V) is developing one of the world's largest primary silver deposits, La Preciosa, located near the city of Durango, in Durango State, Mexico. The La Preciosa silver project and adjacent mineral concessions cover 32,400 hectares (80,000 acres) of contiguous mining claims. ![]() On August 11, 2011, the Company released the results of a positive Preliminary Economic Assessment for La Preciosa Project, and the Company has now published the Preliminary Economic Assessment on SEDAR. The updated fully diluted resource estimate, effective June 30, 2011, is shown in this table:
(1)Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. No Mineral Reserves have been estimated. Mineral Resources have accounted for minimum mining width and planned mining dilution. (2)Cut-off grades are based on operating cost estimate and metal prices of $25/oz silver and $1250/oz gold. Metal prices are based on a weighted average of historical three year average daily silver prices and a two year future price forecast. (3)Silver equivalent grade values assume a gold to silver ratio of 50 to 1 based on the assumed metal prices. The metallurgical recoveries and refining charges are assumed to be the same for silver and gold for the purposes of the equivalence calculation only. The resource estimate is based on 667 drill holes completed as of November, 2010, by Orko Silver and Pan American, working with Major Drilling International. Pan American drilling, combined with Orko's 2005-2008 drilling, surpasses the 242,000 metre mark. There remains significant potential for defining a larger resource. On April 14th, 2009 Pan American Silver Corp. and Orko Silver announced that they have agreed to form a joint venture to develop the La Preciosa project. Pan American will contribute its demonstrated mine development expertise, as well as 100% of the funds necessary to develop and construct an operating mine, in consideration for a 55% interest in the joint venture. Orko Silver retains a 45% interest fully carried to production. Orko Silver's shareholders will benefit from the financial capacity and extensive mine development expertise that Pan American brings to the joint venture as well as retain the upside potential for the discovery of additional resources from Orko Silver's exploration team. Pan American Silver is examining various scenarios for the Feasibility Study at La Preciosa, including coordinating the work of external engineering studies.
