Report: Brooks A caved adit and a prospect pit explore a N30W fault zone in Devonian Jefferson dolomite near its contact with diorite related to the Boulder Batholith. The adit is caved and trends N20W. The zone and the surrounding limestone contain quartz, garnet, calcite, chlorite, tremolite, and secondary copper minerals. Supposedly there were some small pockets of very rich gold ore, worth $4-5 per pound (Sahinen, 1950). There is a spring below the workings, but waste dumps do not appear to affect it. The dump is loaded with copper; seems to be a garnet skarn. The dump is about half copper and half iron cap (gossan). There is a spring. Sample BJB-1, a dump composite, was taken.
