| Summary : A tin and copper mine which exploited lodes in the valley near Trelissick and Carnmeal Downs. It was first documented during the early 16th century as an openwork and was operated mainly by openworks and adits until the 19th century. Shaft mining took place between 1836-1840 and 1847-68 producing tin, copper, arsenic and wolfram (tungsten). In 1864 the mine was served by five engines which included a 70-inch and 40-in pumping engines, 24-inch and 20-inch winding engines and a 36-inch stamping engine. The mine had 457 employees. The mine was reworked in 1877, and worked sporadically between 1892-1909. The mine produced 2,992 tons of tin, 322 tons of copper. It also produced tungsten and arsenic. |
