History
Founded over 450 years ago, the town of Coneto de Comonfort was originally established as a mining community. It is located in the heart of the Coneto Mining District in the "Mexican Silver Trend", on the Mesa Central, east of the Sierra Madre Occidental mountains. This epithermal gold and silver-rich district has a long history of exploration and small scale production, dating back to the mid 16th century. The district has been explored by Orex Minerals Inc. (TSX.V: REX) and their project partner Fresnillo plc (LSE: FRES).

Geology
Gold and silver mineralization is hosted in over 40 epithermal quartz veins and breccias of low to intermediate sulfidation. A corridor of veining extends northwesterly for 17 km and has a width of about 4 km. Individual veins can be traced for up to 2 km and vary from 1 to 20 metres thick. These are exposed in an erosional window of Lower Volcanic Series (LVS) andesite domes, flows, tuff and agglomerate, surrounded by Upper Volcanic Series (UVS) rhyolites and dacites. The main silver-bearing mineral is acanthite and native gold is associated with hydrothermal hematite. The base metal minerals galena, sphalerite and minor chalcopyrite increase with depth. Associated with the mineralized structures are hydrothermal alteration zones, including kaolinitization, silicification, and pyritization.[5]
