Production

Operation type: Surface-Underground
Deposit type: replacement, fracture fillings; secondarily-enriched.
Production size: Small
Development status: Past Producer
First production started: 1875

Geology

Host rock:Harmony Formation, Battle Formation, Antler Peak Formation
Host type:Sandstone,Siltstone,Limestone,Shale
Associated type:Granodiorite,Quartz Monzonite,Porphyry
Structure:North-south-trending fractures exert minor control on mineralization. Low angle NNE-and NNW-trending-faults have been important in localizing supergene ore bodies., Major deformation of the Paleozoic rocks occurred during the Mississippian Antler and Late Permian -Early Triassic Sonoma orogenies before the intrusive and mineralization events occurred.
Alteration processes:Strong-potassic, silicic, sericitic, propylitic, pyretic alteration of host granodiorite to quartz monzonite porphyry
