This week several companies posted drilling intercepts from a variety of mineralizing systems. Structurally controlled intermediate sulfidation epithermal vein systems are represented by Prime Mining’s Los Reyes, Vizsla’s Panuco, both in Sinaloa, Silver Tiger’s El Tigre in Sonora and Defiance’s San Acacio vein system at the Zacatecas Silver project in Zacatecas. Porphyry copper systems are represented by Oroco’s Santo Tomás project in Sinaloa, with copper and gold intercepts, and Aztec’s Cervantes project in Sonora, with its gold intercepts. Silver Dollar’s La Joya, in Durango, is a little bit more difficult to categorize, but tentatively is mineralization related to intrusive bodies, then overprinted by intermediate sulfidation mineralization, which is a trade mark of several deposits in Mexico.
