Commodity: Silver-Gold
Deposit Type: Low Sulfidation Epithermal Au-Ag
Location: Sonora, Mexico
Size: 807 hectares
Status: Available for Option

Los Cuarentas is a low sulfidation epithermal Au-Ag target characterized by strong argillic and phyllic alteration surrounding low sulfidation epithermal vein systems that host gold and silver mineralization. Vein textures and silica polymorphs suggest that the higher levels of the epithermal systems are present throughout the under-explored district. Hydrothermal alteration is overprinted in places by strong oxidation after pyrite and other sulfides. Several target zones have been identified and most are ready for drilling; these are named: Santa Rosalia, Santa Rosalia Sur, and El Sombrero.

The property is located in northern Sonora, 170 km northeast of Hermosillo and located 17 km northwest of SilverCrest Metals’ Las Chispas Mine (PEA (Preliminary Economic Assessment), estimates annual production of 9,559,000 oz AgEq[1]). The Los Cuarentas Project is also located 15 km northeast of Premier Gold’s Mercedes Mine, (produced 89,699 oz Au and 321,814 oz Ag in 2018[2]).
