Mining Operations at Mount Mica & Orchard Pit Mines, Oxford County, Maine.

These charts prepared by Dr. Skip Simmons and Al Falster from their analysis of material recovered from pocket MMP28-04, identify four specimens of tourmaline. They are elbaite, rossmanite, foitite and schorl. Their work is the first to confirm the occurrence of rossmanite at Mt. Mica. In addition to the pocket 28 material, tourmalines mined by A.C. Hamlin in 19th century and by Frank C. Perham in the 1960s were also analyzed.
