Southwest shore of Pyramid Lake
Structure: Breccia Zone

Alteration: Quartz-Sericite-Pyrite To Propylitization

Deposit type: Porphyry Mo, low-F

Geology: Quartz monzonite porphyry intrudes ash flow tuffs of hartford hill rhyolite thin oxide zone caps primary sulfides. Alteration and mineralization present in the quartz monzonite stock suggests the possibility of a commercial body of moly ore.

Ore(s): Breccia Zone
