|Location and accuracy||The Sugarloaf Association placer gold occurrence is along a small stream about two miles north of the summit of Sugarloaf Mountain; it is in the center of sec. 33, T. 14 S., R. 40 W., of the Seward Meridian. The location is accurate within one-quarter mile.|
Geologic descriptionThis gold-bearing stream drains Sugarloaf Mountain and nearby highlands which are are underlain mostly by Lower Tertiary andesitic and dacitic lava flows and breccias. The Tertiary rocks are intruded or overlain by minor basaltic plugs, dikes, and flows (Riehle and others, 1993). Activity at this occurrence seems to be limited to claim staking and minor exploration. Several blocks of claims, denoted as Nos. 1 and 2 were filed in 1978-1984.
