Deposit | Oxidized and enriched ore is present but not economically important. At the historic mine, there were 2 ore bodies. The mined-out East ore body was hosted by siliceous and calcareous conglomerate within the lower part of the Battle Formation, which was altered to quartz-k-spar-biotite rock with sulfides distributed throughout. The West ore body is in a garnet skarn surrounded by an envelope of diopside, tremolite-actinolite, and biotite, north of and adjacent to the granodiorite contact in Copper Canyon. Total sulfide content (mainly pyrite and pyrrhotite) increases to as much as 75% by volume toward granodiorite contact, with chalcopyrite important closer to the contact. Metal zoning is well developed. The average size of the ore body was said to be 1,500 x 600 x 180 meters. |
