Minaurum Gold has entered into an option agreement to earn a 100 percent interest in the La Quintera Silver Project.
According to the press release:
Quintera encompasses a number of wide, high-grade epithermal veins with significant historical production. The project has seen little modern exploration and has never been drilled.
Quintera covers 4,698 hectares and is located 8km west of Alamos, 45km northwest of Pan American’s Alamo Dorado silver mine, and 15km south of Cobre Del Mayo’s Piedras Verdes copper mine. Quintera hosts excellent infrastructure and is fully permitted from exploration through to production.
The Quintera Project, which includes the Promontorio, La Quintera, La Aduana, and Minas Nuevas mines, is estimated to have produced more than 120 Moz of silver from about 1680 to the early 1900s. Vein widths average 4m but locally range up to 20m. The primary target vein has a strike length of 3.5km and the entire vein system measures more than 7 km long. Historical records of selective mining indicate grades of over 2,000 g/t Ag were recovered using a cut-off grade of 1,000 g/t Ag.
Director of Minaurum, Dr. Peter Megaw, stated “The Quintera vein swarm produced the majority of the silver mined in the historic Alamos Silver Camp and has somehow eluded systematic exploration for over 100 years. We look forward to having the first crack at applying modern epithermal vein exploration concepts to this system.”
The last known production in the district occurred between 1948-1957 in which an American Company processed historical dumps at a rate of 300tpd. In 2012, the Servicio Geológico Mexicano (“SGM”) took a total of 105 samples over 3 waste piles and 4 tailings ponds at the La Quintera and the Promontorio mines. Based on the results, the SGM estimated that the Promontorio Waste Dump hosted 157,728 tonnes grading 169g/t Ag, 0.69g/t Au, 1.61% Pb, 0.77% Cu and 3.12% Zn. SGM also estimated that the Quintera dump hosted 66,712 tonnes grading 173g/t Ag, 0.57% Pb and 0.84% Zn. Neither of these estimates is NI43-101 compliant.
