Other Names: Virgin Mountain chrysoberyl Mine , Mica Notch deposits and Leavitt claims
Commodities: mica and beryllium
Location: Township 15 S, Range 71 East, Section 17,18
History: Earliest work was done for mica in about 1900; some beryllium ore was produced in 1935.
Geology: Muscovite mica occurs in pegmatite dikes associated with chrysoberyl, beryle, garnet, magnetite, and tourmaline. The dikes cut Precambrian garnet-mica schist; gneiss foliation trends northeast and dips southeast. The mica occurs in books up to several inches thick and g to 8 inches square. Specks of foreign material are present and it is not cleavable in large sheets.

This is what remains of the old mining shack of the Mica Notch Mine. You can can still see some of the old shingles from the roof:
