International Northair Mines Ltd. is very pleased to announce the acquisition of a significant package of mineral concessions totaling nearly 32,000 hectares contiguous to the Company’s La Cigarra silver project located in the state of Chihuahua, Mexico. The land package was acquired through an option agreement, staking and purchase to cover permissive ground that surrounds the Company’s original La Cigarra concessions. Drilling at La Cigarra by the Company has outlined a potentially surface minable mineralized system with an open ended strike length in excess of three (3) kilometres. An initial resource estimate utilizing the results from 111 core holes and 11 reverse circulation holes covering 2,400 metres of this system is presently being calculated.

MAG Silver Corp. is pleased to announce that Roscoe Postle Associates Inc. has completed the first independent mineral resource estimate for the Bridge Zone/Jose Manto on its 100% owned Cinco de Mayo Property in northern Chihuahua, Mexico. Inferred Mineral Resources are estimated to be 12.45 million tonnes at 132 grams per tonne (3.9 ounces per ton) silver, 0.24 g/t gold, 2.86% lead, and 6.47% zinc (9.33% lead plus zinc).

Wealth Minerals Ltd. is pleased to announce that geological mapping and sampling at the Valsequillo property has provided confirmation of bulk-tonnage potential. In the Western Corridor (Figure 1, Table 1), discovery of additional veins and silicified fault zones now outlines a priority target area measuring approximately 900 metres long and 1,000 metres wide. Sampling of artisanal workings (29 samples) returned encouraging grades peaking at 494 g/t silver, 1.07 g/t gold, 11.9% zinc, 4.09% lead and 9.47% copper (data ranges and mean grades are provided in Table 1). Phase II exploration is now being planned with the goal of defining priority targets for drill testing.

SilverCrest Mines Inc. is pleased to announce the results of an additional 15 holes of the Phase II drill program and additional surface sampling currently underway at its La Joya Property in Durango, Mexico. The Phase II drill program has been expanded by 10 holes to 90 holes totaling 20,000 metres. Phase II drilling reported to date has extended the Main Mineralized Trend (“Trend”) beyond the area containing the current Inferred Resource of 101.9 million ounces Ag Eq.(i) (see News releases dated March 20 and May 7, 2012 and attached figure). Newly constructed drill roads have exposed high grade surface mineralization with Ag Eq values ranging from 72.6 grams to 187.6 grams over sample intervals ranging from 39.7 metres to 99 metres. Drilling and surface sampling has now extended the Trend to approximately 2.5 kilometres with an average width of approximately 700 metres.
