Gold-Silver
The San Pedro Analco property is a past producer consisting of 1,136 hectares covering an extensive low sulfidation silver/gold epithermal system. The Project is located within the Cinco Minas - San Pedro Analco mining district, 70 kilometers northwest of Guadalajara. The Project has excellent infrastructure with road access, ample water available, and a high voltage transmission line less than one kilometer from the property. The mine reportedly operated until 1988.
Location & Access
San Pedro Analco is located in Jalisco State, 70 km northwest of Guadalajara, Mexico’s second largest city.
Land Status
Premium has an option to earn 100% of 1,136 hectares by making staged cash and share payments and exploration expenditures over three years.
Exploration Targets
San Pedro Analco hosts an extensive low sulfidation silver/gold epithermal system with at least five vein structures on the property.
Mineralization
Silver and gold with lesser amounts of zinc and lead within veins and breccias.
The district is currently the focus of significant exploration activity by several junior mineral exploration companies. Located immediately southwest of San Pedro Analco, Stroud Resources Ltd. report samples from old mine workings which assayed “37.6 grams to 1466.6 grams silver per tonne and 0.17 grams to 3.94 grams gold per tonne” from their Santo Domingo Project. Eleven kilometers south, Bandera Gold Ltd. is exploring the Cinco Minas area, where in the 1920s, 15 million ounces of silver and 97,500 ounces of gold were produced from 1.2 million tons of mine ore, with recoveries of the silver and gold ranging from 88% to 90.5%. The main mineralized zone had a length of 550 meters and was mined to a depth of 700 meters.
San Pedro Analco is a past producer, reportedly operating as recently as 1988, with production from five underground mines. There appears to be extensive mining, but production data is unavailable. From observations made during the initial mapping by Premium geologists there is little indication of any mining activity covering the 700m between the historic mines to the north and south, or that any historic exploration activity was conducted beyond the existing mine workings. Therefore, it appears that there is approximately 700 meters of undeveloped and unexplored potentially mineralized structure between the mines, as well as down dip extensions below the historic mines.
A preliminary sampling and mapping program was conducted in four of five of the larger mines. A total of 1,600m of mine workings were mapped from which 71 chip samples and nine grab samples (from ore chutes) were collected from five mines. For the four mines mapped, the results for samples with greater than 100 g/t Ag and/or 1.0 g/t Au are presented in the tables below. Thirty-seven of the 80 samples collected returned elevated gold and/or silver values.
The next phase of exploration will include surface and underground mapping and sampling in preparation of a geophysical survey to map structures at depth. This will be followed by drilling to test the extent of mineralization outward from the mines.
