Commodity and development information
Well developed mineralogical zonation in district is concentric around the deposit. Preliminary fluid inclusion homogenization temperatures 217 to 434 degrees C. Location is that of Corralitos gossan (oxidized surface expression of the Tahonas porphyry copper deposit). Corralitos is a porphyry copper prospect held by EXMIN in 2008 at the edge of the Batopilas silver camp and 4.5 km NW of the Satevo prospect. Phelps Dodge previously explored the area and defined a small near-surface oxide copper body, but determined that it was not big enough for them. However, little work has been done surrounding the copper core to the deposit, and there is potential for silver mineralization surrounding the intrusion. On Sinaloa-Durango border. Cluster of deposits. System is tilted 90 degrees on its side. Mo-rich core and fault between Cu-rich zone. Approximately 5 km W is the Los Ocotes prospect.
