Aura has been exploring the Taviche District project area located in Oaxaca State, Mexico since 2006. The project area is located about 10km south of the City of Ocotlan where the Company has a field office.
The Taviche District has a long history of mining. The San Jose Mining District has been active intermittently since Spanish colonial times and was Mexico's first historical silver-mining area containing more than 60 recorded underground mines. As is widely known, Mexico ranks as the largest silver producer in the world. In fact, the project is adjacent to Fortuna Silver Mines Inc. San Jose gold/silver Mine which in 2015 produced 4.9 million ounces of silver and over 38,000 ounces of gold. The mine is 40km to the west of the property boundary.
The Taviche Project currently consists of one permitted concession held 100% by Aura.
The San Jose mining district offers a wide number of ore types but primary targets sought after by Aura are epithermal silver (gold) deposits. Surface exposures are dominated by hydrothermal breccias with lesser amounts of massive to banded quartz-chalcedony veins. Historical mining occurred intermittently along the vein systems at structural intersections of cross-cutting veins. Samples from the old mine dumps commonly contain in excess of 5 g/t gold (Au) and 200 g/t silver (Ag) with values up to 94.7 g/t Au and 1,845 g/t Ag.
The major target within the Taviche concession has been the 7.5 km long Higo Blanco mineralized corridor where epithermal-style gold stockwork mineralization was discovered that flanks and caps silver-bearing silicified limestone breccias. An 865,000 tonne inferred ore zone grading 119 g/t silver and a 3.3 million tonne inferred ore zone averaging 0.51 g/t gold has been outlined by 14 drill holes. Deeper drilling to test for higher grade gold in the Mezcal vein structure is required where grades to date appear to be increasing with depth. In addition, future programs would include further testing of the extension of the silver mineralization with deeper holes to locate the source testing several "organic geochemical" targets. The Company is actively looking for a partner to continue the drilling.
