La Cocolmeca

La Cocolmeca is a northeasterly trending fault that juxtaposes Paleocene bimodal volcanics in the southeast against Late Cretaceous and older rocks to the northwest. This fault is mineralized at several locations including the past-producing San Antoñio Gold Mine.

Historic production from La Cocolmeca is mostly from San Antoñio Mine, a surface cut located 280 meters northwest of La Gloria. Host rocks in the hanging wall northwest of the mine are pyroclastic rocks correlated to the Socavón member of the Tarahumara Volcanic Arc. The footwall to San Antoñio is shoshonite in bimodal Paleocene volcanic rocks. Mineralization consists of chalcopyrite, sphalerite, and galena in white to grey quartz. Vein selvedges are altered to white mica. Wall rocks peripheral to the vein are pervasively silicified and contain stockworks of quartz with piedmontite (pink Mn-epidote), sphalerite and galena. Most of the sampling is from surface and underground. In 2021 Brigadier Gold successfully intercepted precious and base metals this vein in DH-BRG-026 and -027.
