Western States Copper Mine; Quartz Creek Mine


A Cu-Mo-Au-Ag mine located in the NW¼ sec. 16, T. 24 N., R. 10 E., on Quartz Creek.

It worked 2 mineralized breccia pipes called the East (Rainy)and West (Poncho) areas. One rich pod of ore produced significant silver values in 1952 - 1953, by the Gilbreath brothers. The old mine site, tunnels, and tailings have been reclaimed and buried, 2011.
Structure: Strong E-W Sheeting

Alteration: Potassic, Propylitic, Silica Flooding

Tectonics: Cascade Volcanic Arc

Commodity: Commodity distribution is zoned. Slight radioactivity recorded at one location. Pb isotope data is available in church and others

Deposit: Deposit has been given the informal name of a breccia pipe cu deposit, for which there is no published model. Two eliptical mineralized breccia pipes, dimensions are for east pipe. A low-grade porphyry system may be present at depth mrds record w017919 has been merged with this record and deleted

Development: Deposit has been drilled several times since 1957.

Geology: Grant (1969) refers to host rocks As quartz creek stock of the snoqualmie batholith. Deposit is near west-central contact of snoqualmie batholith. Calligan formation and mount garfield volcanics in grant are probably equivalents of western melange belt and unnamed volcanic rocks of tabor and others, respectively.

Rock formation(s): Snoqualmie Batholith, Northern Phase;Snoqualmie Batholith, Northern Phase
