Three companies announced during the week results from drilling campaigns on projects in Mexico.

First Majestic Silver released results from drilling on the Sinaloa-Elia, Roberta, Santa Teresa and Coronado veins within its San Dimas project in Durango. The program was designed to explore for new veins, expand mineral resources, and upgrade inferred mineral resources to indicated mineral resources. The company is exploring for extension of mineralized zones not previously tested by modern techniques. The district hosts classic low sulfidation epithermal mineralization.

At the San Marcial deposit in the Plomosas project in Sinaloa, GR Silver Mining presented results from the ongoing step-out drilling campaign. “Drilling at the Parallel Breccia target that hosts the latest results is designed to explore the down-dip continuity of anomalous surface channel silver results in the vicinity of the Resource Area boundary”. This area presents intermediate sulfidation mineralization.

Avino Silver and Gold Mines released results from four twin holes at La Preciosa, in Durango, aimed to replicate values encountered in historic drilling. “mineralization in the area occurs in veins, veinlets, and stockwork. These veins average in true width less than 15 m (Martha Vein) and consist of several stages of banded crustiform to colloform, quartz (and cryptocrystalline quartz at shallow depths), adularia, barite, and typically later carbonates (both calcite and rhodochrosite); illite commonly replaces the adularia. There are variable amounts of pyrite, sphalerite, and galena plus argentite, and variable amounts of tetrahedrite – tennantite, freibergite, and Ag sulfosalt”. An interesting feature in the zone is the combination of low and high angle intersecting structures.
