A gold prospect with surface and underground workings located in the East-center & SE¼SE¼ of sec. 7, T4S, R13W, about ¼ mile south of the Golden Harp claim, eastern foothills of the Tank Mountains (NE edge of the Puzzle Mts [portion of the Tank Mts]).
Mineralization is varied: (1) Scattered, short, lenticular, and narrow, gold-bearing quartz, carbonate, iron oxide and minor, partly oxidized, copper and iron sulfide veins in fissure zones in Mesozoic granitic intrusive and metamorphic schist, with dioritic to rhyolitic dikes. Wall rocks are sericitized, silicified, and carbonatized. Gold concentrated by weathering in near-surface iron oxides and quartz. The quartz vein is within somewhat foliated chlorite schist and schistose diorite. This vein strikes N.30ºW. and dips 45º NE. It is heavily shattered and, as exposed in a shallow shaft & open cut, apparently has been cut off by a fault.
Local structures include the vein which is heavily shattered, and has apparently been cut by a fault. Veinlets of ferroan calcite traverse the vein along parallel fractures. Tectonic influences include block faulting. In the Puzzles area, the schists contain several iron-stained quartz stringers that, in the early days, yielded a few small, rich pockets of gold ore.
Workings include a shallow shaft and open cut.
