SUMMARY
Three principal Au-Ag-bearing structures uncovered at the Baluarte property are characterized by 300 m to 1 km-long silicified and hematized veins and breccias carrying average Au and Ag (g/t) values of 9.93 g/t Au and 381 g/t Ag (Santa Rita), 5.84 g/t and 26 g/t Ag (El Sacrificio) , 4.18 g/t Au and 291 g/t Ag (La Campana east) and 16.67 g/t Au and 626 g/t Ag (La Campana west). These elevated gold and silver concentrations indicate a favorable geological environment for the discovery of a Au-Ag mine in a little explored area of the southern Sierra Madre Occidental.
The low-sulfidation epithermal Au-Ag Baluarte property is located 75 km east from the city of Mazatlan, Mexico on frontier between the Sinaloa and Durango states. The property consists of three mineral concessions totaling 1000 hectares located on the western flank of the Mid-Tertiary Sierra Madre Occidental geological Province. The mineralized structures were emplaced in the Oligocene Upper Volcanic Supergroup within a thick sequence of rhyolitic to andesitic breccias and tuffs accompanied by scattered andesitic porphyric flows.
The La Campana showing forms a 1 km long structure oriented 255º dipping 74º to the NW. The main showing exposes a strongly altered Au and Ag mineralized breccia previously mined along an adit that reveals brecciated andesitic rocks that show extensive signs of hematization and silicification.
