Sierra Madre Developments Inc. and its partner Riverside Resources Inc. have announced drill results including 20.9 meters of 1.01 g/t gold from the first two drill holes completed as part of the 2012 drill program at the El Capitan Target (a bulk tonnage oxide gold deposit), which forms part of the Company’s Penoles Project in Durango, Mexico. Drilling in 2011 tested approximately 60% of the strike extent of the zone and the objective of the current drill program (funded by Sierra Madre) is to test the down dip extent, possible extensions to the west and provide sufficient drill hole density for an initial resource calculation for El Capitan.

Bearing Resources Ltd. announces results from its 1,172 metre (7 hole) diamond drill program at the Parrandera gold-copper property located in the Mapimi region of Durango, Mexico. The Parrandera property was the initial and smallest property optioned when establishing the Mapimi project (40,000 hectares). The drill program was highlighted by drill hole PA12-01 which returned 12.95 metres grading 0.858 grams per tonne (g/t) gold beginning at a down hole depth of 16.3 metres. While the drill program identified gold and copper mineralization over narrow intercepts, the results did not meet Bearing’s exploration target criteria therefore the Parrandera property will be returned to the property vendors.
