Day: June 27, 2012

Soltoro Ltd. recently concluded a ground geophysical survey over the entire El Rayo Project which served to identify a possible structural extension to the gold resource area. To date Soltoro has defined Indicated Mineral Resources of approximately 22,600 ounces of gold and Inferred Mineral Resources containing approximately 18,900 ounces of gold on the northwest end of the El Rayo structure. The most promising area sampled to date is the La Ocotera zone, which is located to the northwest of the El Rayo gold resource and would add approximately 750 metres of prospective structure to be explored. Results of trenching completed to date include intercepts of 4.8 metres of 1.01 g/t gold and 6.5 metres of 0.91 g/t gold in the La Ocotera area. Selected results from trenching and rock sampling were returned as follows:

Riverside Resources Inc. and its partner, Sierra Madre Developments are pleased to announce additional drill results from the 2012 drill program at the El Capitan Target (a bulk tonnage oxide gold deposit), which forms part of the Company’s Peñoles Project in Durango, Mexico. Drilling in 2011 demonstrated good continuity over a strike length of approximately 700 meters (referred to as the Main zone – see press release dated October 24, 2011) and the current program (funded by Sierra Madre) is designed to test the down-dip extent of mineralization and provide sufficient drill-hole density for an initial resource calculation for El Capitan.

Westminster Resources Ltd. announces the first ever diamond drill hole has been completed at the Cumbral copper, silver and gold project located in Sonora, Mexico. The initial phase expected to be 1,200 meters (of a total planned 4,000 meters) targets four geophysical anomalies. The balance of the program, weather permitting (rainy season), will evaluate other numerous prospects identified on the 8,000 hectare property.

Quaterra Resources Inc. and 50% joint-venture partner Blackberry Ventures 1, LLC, today announced that an updated independent resource estimate has substantially increased contained silver ounces at their Nieves property in northern Zacatecas, Mexico.

Westridge Resources Inc. announces that the Company plans to focus the next phase of drilling and sampling on its Charay Project in Sinaloa State, Mexico, with a view to define NI 43-101 compliant resources on the high grade El Padre vein system in the near future.
