Otherwise known as Hemerdon Bal, Hemerdon Mine is an abandoned open-cast tungsten mine near Plymouth. The locality is famed for its high quality scorodite (among the best in Europe) and cassiterite. On 4th December 2007 it was announced that an Australian company, Wolf Minerals LLC, had acquired the rights to mine this deposit, and current plans are to reopen the site as a full-scale opencast metal mine for tungsten and tin, producing up to 3000 tonnes of tungsten metal per year. The only recorded output is 31 tons of wolfram (tungsten) and 7.5 tons of black tin between 1918 and 1920.
