The Santa Teresa trend is the longest and best developed vein system within the Northwest Vein Corridor (NWC) at Abriaqui (Figure 1). Surface outcrop is minimal and until recently, Santa Teresa was characterized by only two drill intercepts and a number of samples taken from existing underground mine workings. Artisanal mining historically concentrated only on the high grade core of the veins, and mine workings available for sampling did not necessarily represent the full thickness of the mineralization. To date this has ranged up to 4.1 meters in the drill holes on Santa Teresa. In a recent program of mine mapping (see Press Release of June 23, 2021) several new mines were accessed which included areas where crosscuts were developed perpendicular to the vein trend. Recent channel sampling along these crosscuts has allowed for a much better characterization of the full width of mineralization. Phase 2 drilling, currently underway, is further testing Santa Teresa and several other veins in the NWC. Results from the first two holes will be reported soon.
