Deposit: Best vein material is associated with the incline shaft in main part of camp (sample site 2924). Vein material includes hydrothermal breccia with chalcopyrite, and possible tetrahedrite. Sample 2925 was from a shaft on hillsdie SW of main camp a few hundred yards. Dump material here included granite, epidote, and less mineralized material containing pyrite, sdierite, and chalcopyrite. Iron oxides are common in all veins. Discovery year: 1930's ?

Deposit type: Low-sulfide Au-quartz vein

Development: No activity at time of examination in 1985. Workings appear to date from 1930's.
