Report: This mica deposit had one open adit (at least 40 ft long) and highwalls when visited 08/10/99. The timber and lagging were buckling and splintering. The adit was caved from above at the 40 ft length. It was dry. Four lengths of 18 in. diameter plastic culvert were on the ground in front of the adit and a pickup truck was parked nearby. There were two open cuts on the hillside above with 10 to 20 ft slopes. Mica (muscovite?) was abundant on the dump and the host rock was gneisses, silty quartzite, graphic granite, and amphibolite. It was mined in 1954, and 1956 through 1962 (McMannis and Chadwick, 1964).
