Here is an exploration from February 2023. This mine was owned by the Golding-Keene Co., out of Keene, who operated the mine between 1942 and 1944, primarily for feldspar and mica. The site consists of a massive cavern, a short tunnel, and a flooded shaft that is said to extend 90 feet below the surface.
