Mount Mica Discovery

Gary Freeman began mining pegmatite at Mount Mica, Maine, in August of 2003. For a number of years, he posted mine information and updates of mineral finds on his website http://www.coromotominerals.com/. That mining history with illustrations through 2008 remains on line. However, Gary’s mining has continued ever since with Brian Pedersen. In the course of their more recent work, they have encountered pockets containing lepidolite and polychrome tourmaline for which the mine is renown. However, a recent large pocket proved exceptional on January 3, 2019. This video, taken by Brian Pedersen and provided by Gary Freeman, shows Gary’s wife, Mary, extracting a large and brilliantly blue-green tourmaline. Their exploration of the large pocket continues.
