The mine was first operated by Frank Tucker of the Bristol Construction Company, probably during the summer of 1940, when several cuts were made in three pegmatites. Cut A in pegmatite no. 1 is about 90 feet long, 12 to 22 feet wide, and 5 to 15 feet deep. The deepest part is a small inclined stope down the dip of the pegmatite. Cut C in pegmatite no. 2 is 15 feet long, 10 feet wide, and 5 feet deep. Cut D is 10 to 15 feet long, 10 feet wide, and 5 feet deep. Cut E in pegmatite no. 3 is 11 feet long, 7 feet wide, and 2 to 3 feet deep. Cut F is 28 feet long, 16 feet wide, and 5 to 10 feet deep. In July 1943 the mineral rights were leased by William Lislie of Melrose Highlands, Mass. Cut B, 15 feet long, 10 to 17 feet wide, and 5 to 10 feet deep was excavated southeastward into the hillside along the strike of pegmatite no. 1. From September to December 1943 the mineral rights were leased by the Hill Mining Co. of Bristol. The inclined stope in cut A was drained, partly cleaned, and then deepened by underhand stoping to about 40 feet (measured along the dip). Cut B was extended southward approximately 15 feet.
