Geology

Host type:Rhyolite,Tuff
Associated rock:Auld Lang Syne group
Associated type:Metasedimentary Rock
Structure:Northerly and northeasterly structural trends dominate the area. Breccia zones are associated with rhyolite intrusives that cut rhyolite flows and metasedimentary rocks. Oxide ore zone in section 9 appears to follow a NE trend. The reported sulfide zone in sec. 10 is exposed along a narrow drainage that extends south from Willow Canyon. Metasedimentary rock outcrops limit the extent of the disseminated, rhyolite-hosted ore zone to the NE and east. The earlier-prospected deposit is a polymetallic sulfide vein containing silver-lead-copper mineralization. Drilling in 1984 confirmed the existence of a large deposit high in silver in a 100-ft vein along a N-S-trending fault structure.
Alteration processes:Alteration is widespread and consists of silicification and argillization.
