Resumen
This presentation of the San Francisco project (3600 ha) begins by explaining the history of the San Francisco de los Andes Mine that was in production between the 40s and 70s of the last century, producing bismuth, copper and gold. The history of the Exploration / Drilling of this Mine is also presented. The San Francisco breccia corresponds to the Pipe-type Breccia Model (Kirwin 2017 2020), not related to porphyries, which normally occur in the cap of granite batholiths or in their box rock. To date, including Compañía Aguilar, Ministry of Mining and Aurora Mining, more than 11,600 meters of diamond have been drilled. Aurora Mining is already in its third phase of drilling. The first two were in 2019 and 2020. The Company in its three campaigns is exceeding 10,900 meters of drilling. These types of pipe gaps extend for long distances at depth and tend to widen. Current Aurora drilling is confirming this theory, by drilling deep up to 625 meters, observing that the gold, silver and copper mineralization remains open at depth, as observed in hole 039 (72m @ 3.47% Cu, 0.71 g / t Au & 100 g / t Ag - 6.7 g / t AuEq; 5.0% CuEq) from 397m). Aurora is complying with an anti-covid campaign applying a strict biosafety protocol.
