Deposit MINERALIZED SHEAR ZONE WITH OXIDIZED, ARGENTIFEROUS LEAD ORE.
Deposit THE KEYSTONE MINE, LOCATED ON THE N. SLOPE OF SPRUCE MT., IS DEVELOPED BY OPEN CUTS, SHALLOW SHAFTS, AND SHORT ADITS. A MINERALIZED SHEAR ZONE OCCURS AT THE SHAFT, AND SILVER-BEARING OXIDIZED LEAD ORE HAS BEEN MINED FROM IT. THE KEYSTONE HAS HAD A SMALL PRODUCTION, MOSTLY PRE 1916.
