Sierra Madre Developments and its partner, Riverside Resources Inc. are pleased to announce additional drill results from the 2012 drill program at the El Capitan Target (a near surface, shallow dipping, oxide gold deposit), which forms part of the Companys Peñoles Project in Durango, Mexico. Drilling in 2011 (18 holes) indicated potentially economic grade mineralization over significant widths (30 to 110 meters) and good continuity of the mineralized zone over a strike length of approximately 700 meters (referred to as the Main zone see press release dated October 24, 2011). The El Capitan Zone is exposed in the side of a low ridge and most of the 2011 program consisted of inclined holes drilled from the top of the ridge at an azimuth of 030 degrees (perpendicular to the strike of El Capitan). The current program consists of an additional 20 holes (funded by Sierra Madre) designed to test the down dip extent of mineralization and provide sufficient drill hole density for an initial resource calculation.
