A Cu,Zn,Pb claim

This claim is located on the Spirit Lake-Guler Trail.

It worked a shear zone in basalt.

Developments include a 340' drift and a shaft.
Tectonics: Cascade Volcanic Arc

Deposit: Shear zone in basalt contains irregular lenses of quartz from 1 in.-2 ft thick. Glassy white and gray quartz contains sparse sulfide minerals. Ore minerals also occur along fractures in the footwall. A shaft was sunk 80 ft on an unexposed mineralized quartz vein in diorite. Quartz fragments on dump of shaft contain minor disseminated sulfides. Consists of several unpatented mining claims. Location map available, moen (1977). ; info.src : 1 pub lit; 2 unpub rept

Deposit type: Polymetallic veins

Development: Deposit was worked between 1897 and 1934, but production, if any, would have been small

Includes tuffaceous and arkosic sandstone, shale, and carbonaceous shale beds in central and southern Cascade Mountians. Rhyodacite and quartz latite flows in northwestern Ferry County. Comments: Percentage of dacite thought to be andesite in the field; predominate over basaltic and rhyolitic rock (Warren, 1941). Large flows in Ferry County mostly dacite and andesite (Stoffel and others, 1991).
