A copper-silver mine located just west of the Okanogan/Ferry County border on a lobe of Horseshoe Mtn. It worked mineralized shoots up to 16' long in a highly silicified zone in phonolite. This is the southernmost mine on the Silver Bell-Zalla M mineralized belt. Development includes a 97' drift with a 97' winze and small prospect pits. It produced about 60 tons of ore in 1918-1919.
Tectonics: East-West Extension During The Eocene Resulted In Formation Of The Toroda Creek Graben And Other Structures In Which A Thick Section Of Volcanic And Sedimentary Rocks Was Deposited And Preserved (Holder And Others, 1989).
Deposit: The main adit is 97 feet long and trends n45e along a mineralized shear zone. Several small prospect pits were present. Dump samples collected by moen (1980, p. 69) contained a trace to 12.5 oz/ton ag.
Geology: Volcanic rocks in this part of the torada creek graben plot As rhyolite on a tas diagram, but they contain sparse plagioclase and mafic phenocrysts in an aphanitic groundmass that contains abundant plagioclase microlites. Plagioclase phenocrysts are commonly strongly sericitized, and mafic minerals are generally replaced by some combination of chlorite, calcite, epidote, and sphene; shapes of altered mafic minerals suggest that they were originally pyroxene. The presence of silica stringers and veinlets in some of these rocks suggests that silica was introduced during alteration (stoffel, 1990, p. 11).
Ore(s): The Main Mineralized Structure Is A 2-8-Ft-Wide Silicified Shear Zone That Strikes N45e And Dips 50nw. Brecciated And Sheared Volcanic Rock Is Cemented By Quartz And Sanadine And As Much As 5% Fluorite. The Silicified Fluoritized Breccia Body Exposed On The Surface Above The Adit Is As Much As 250 Feet In Diameter. The American Flag Is The Southernmost Property Of The Zalla M-Silver Bell Mineralized Belt That Is About 1 Mile Long And Several Hundred Feet Wide (Moen, 1980, P. 69).
