Guadalupe y Calvo Advanced Exploration Project
The Guadalupe y Calvo gold-silver exploration project is in a previously mined area adjacent to the town of Guadalupe y Calvo in the southwest corner of the State of Chihuahua in Mexico. It is approximately 300km southwest of the city of Chihuahua.
Geological Setting
As with the Ocampo Mine, the Guadalupe project is located in the Sierra Madre Occidental (“SMO”) physiographic province. Volcanic stratigraphy has been broken down into two main groups, the Lower Volcanic Group (“LVG”) and the Upper Volcanic Group (“UVG”). LVG rocks are the host of nearly all of the gold and silver deposits that have been found in the Sierra Madre to date.
Guadalupe y Calvo is a classic gold-silver epithermal district and in general is classified as a pluton low-sulfidation epithermal vein system. The system contains quartz veins, quartz breccias and stockworks hosting economically significant gold and silver mineralization.
The main structural feature in the project area is the Rosario fault complex. Total width of the mineralized zone within the Rosario fault complex is up to 80 metres. Historic underground mining widths of high-grade gold-silver mineralization were up to 10 metres.
Mineralization
The Guadalupe y Calvo project contains an Inferred Resource of 1.08 million ounces of gold and 45.6 million ounces of silver, or 2.02 million gold equivalent ounces (Pincock Allen & Holt November 2002).
