SAN JUAN RC DRILLING
The San Juan zone mineralization occurs right at the contact between flow-banded, flow-dome spherulitic rhyolites and interbedded tuffs, lapilli tuffs with minor black argillite. The contact has been interpreted as a fault. There are several short adits and open cuts within a 0.3 km2 area. A high silver soil anomaly (up to 48.9 g/t) with base metals extends up to 100 m beyond the area of workings. Channel chip returned high silver (average 139.2 g/t) with anomalous gold, zinc and lead.
The Footwall rocks have disseminated pyrite. The host rocks carry elevated barium values. High grade silver was intersected in the upper part of the holes in carapace breccias with sericitic alteration and anomalous antimony. Stockwork MS mineralization is intersected lower in the holes in sericite altered rhyolite. Zinc-lead MS mineralization is generally associated with anomalous arsenic and copper. High grade silver is locally coincident with the MS mineralization. Peripheral alteration is chlorite, pyrite and silica.

Locally the drilling intersected anomalous tungsten suggesting the presence of scheelite and a third, separate mineralization event.
