NARICERO/SAN NICOLAS/REFUGIO RC DRILLING
The zone covers three historic operations and the zone is underlain be a sequence of volcanoclastics, pillow lava and black argillite intruded by a porphyritic intrusion and diorite along the Naricero fault. The Refugio and San Nicolas historic operations are located along a north-south splay of the fault.
Mineralization characteristics are similar to San Juan with zinc-lead MS with anomalous arsenic and copper while the high grade silver is associated with antimony. The drilling also encountered a couple of tungsten intersections.
A couple of holes intersected historic workings.
