An old mine, said to have been worked in 1577 and in the 1680s, it was then worked at various times between 1849-75 when 355 of lead ore concentrates is recorded. In 1874 150 ounces of silver were recovered from 150 tons of lead ore.
Although reopened about 1916-17 by the Union Zinc Company Ltd. and a new mill erected (SH 624412), the mine did not survive the 1921 slump in metal prices in 1921 and has remained inactive since.
