| Deposit | Quartz stockwork is abundant, sericitization is locally prevalent, but K-spar-quartz alteration predominates in most rock. Sheeting in rhyolite averages N20E, dip 75 SW. Locally some flat structures with abundant sericite dip as low as 15 degrees. Mineralized zones in Weaver Rhyolite follow the N20E, 75SW trend of sheeting. Quartz-sulfide stockworks are abundant and presumably control ore distribution. Both oxide copper and chalcopyrite occur but are not abundant. More than 99% of the ore in the pit is oxidized. Sulfide is more abundant in the old pit along the contact lode. Ore averages between 1-2 ounces of silver per ton with a tace of gold. Unoxidized rock contains abundant disseminated pyrite, minor chalcopyrite, and some sulfides in quartz veinlets and arsenic sulfide stockworks. |
