Departure of Principal Officers http://ir.tri-valleycorp.com/secfiling.cfm?filingid=1162677-11-15 In a further reorganization of its minerals operations and an ongoing initiative to reduce operating costs, on January 4, 2011, Tri-Valley Corporation eliminated the separate office of President of Select Resources Corporation, Inc., formerly held by James G. Bush. In December 2010, Select Resources completed the sale of its Admiral Calder calcium carbonate quarry, which was a major asset of Select Resources. The chief executive position at Select Resources will be consolidated with responsibilities for other existing officers. Tri-Valley thanks Mr. Bush for his contributions to the company and its projects.
