Structure: The Trail Creek fault emplaced western assemblage cherts and argillites over transitional assemblage rocks a few miles north of the Blue Jacket Mine The area is transected by a series of northeast-trending faults
Commodity: Ore Materials: galena, sphalerite, tetrahedrite,copper carbonates Gangue Materials: quartz, calcite, pyrite, iron oxides, copper oxides.
Deposit: The deposit is a replacement vein in dark gray, finely crystalline limestone and finely laminated siliceous shale of the Ordovician Aura Formation. Galena, pyrite and iron oxides occur in a white quartz vein with minor amounts of sphalerite and tetrahedrite. The vein also contains boxwork pods of iron and copper oxides. The limestone in the mine area is cut by abundant white calcite veins. Much of the mine dump rock consists of brecciated white vein quartz recemented by silica and iron oxides. Smaller workings in the vicinity of the main shaft are aligned along a fault striking N54E.
Deposit type: Polymetallic veins
Development: The Blue Jacket was the first discovery in the district in 1868 and was worked through 2 tunnels and a shaft until the early 1900s. Two 5-stamp amalgamation mills were built in Blue Jacket Canyon to treat the ore. The bulk of the mine?s production took place between 1876 and 1885. The area was idle by 1908, and all workings were inaccessible in 1956. The area was re-explored in the 1960s, and sporadic mining and reworking of the dumps continued into the 1970s. The Blue Jacket Mine and Millsite are patented.
Geology: The area is transected by a series of northeast-trending faults. Some intrusive granodiorite was also found on the dumps.
Ore(s): The ore deposition was apparently controlled by northeast-trending fissures and shear zones
