Southwest 1/4 of section 17, T10-R6E

A Cu,Au,Ag claim

This claim is located near Black Falls on the Green River.

It worked a leached, silicified, sericitized breccia zone to 2' wide in granite.

Developments include a 80' adit with a 84' drift, 35' shaft, and a 900' adit.

There was minor production prior to 1935.
Alteration: Oxidation, Sericitized

Tectonics: Cascade Volcanic Arc

Deposit: Deposit has been given the informal name of a breccia pipe cu deposit, for which there is no published model. Adit was driven along a persistant fracture zone in quartz monzonite - fractures range from several in.-2 ft thick. Material in fracture zone consists of quartz, gouge, talc, and wall-rock fragments cemented by quartz. Pyrite and minor chalcopyrite are present in quartz and in silicified and sericitized wall rock. Chalcocite containing 80 oz/ton Ag is reported to be exposed at the bottom of a 100 ft winze. About 10 ft belo W drift in no. 2 winze is spectacular exposure of nearly massive bornite and chalcopyrite. Maps of claims and mine workings available and property description, moen (1977, p. 18-24) mrds record m700155 has been merged with this record and deleted

Development: Main development work undertaken by cascadia mining & developemtn co from 1901 through 1905. Drilling in summer of 1991 being undertaken by champion international corp. And continued in 1992
