A mica mine opened by the New Hampshire Mica & Mining Co in 1942, worked continuously until March 1945, except for the period January 1 to April 15, 1943.

About 3,100 tons of rock was mined from the location, exclusive of rock taken from the shaft. Waste rock was hoisted in a skip on a wooden track. Mica was sorted out at the head frame and the waste moved to the dumps.

Granite pegmatite, Alstead field.
