White Mt. Metal Ore Mining District. - Hydrothermal vein deposit on a fault. Often referred to simply as the Gorham Lead mine. The mid-level adit of the complex was called the Galena King adit by the workers, and this name is sometimes still used as a name for the mine. The real name of the site is Mascot Mine. (The Mascot Mining Company, organized in 1881, first worked the deposit.)
This site is in Leadmine State Forest, owned by the State of New Hampshire. Collecting is allowed on the dumps using hand tools only. Entry into the mine itself is forbidden, the openings gated. Collectors are not allowed to dig up the mine road itself.
Reports of bornite and other primary copper minerals from this site which are not listed here have been proven to be in error by recent studies. Analysis of the rarer sulfates and carbonates was accomplished with SEM and XRD. There are still several "unknowns" being analyzed.
