A small copper mine immediately south of Wheal Liberty, which worked an ENE-trending lode that crossed the valley of Trevellas Coombe southwest of Mithian. It was first worked in the years 1805-1817, and reworked from 1825 until 1829. The materials advertised for sale in 1829 included a 54 inch cylinder engine.
In its first period of working, the mine sold 86 tons of copper ore. Another 530 tons of ore were raised in the years 1825-1829.
Most of the workings of this mine were on the west side of the valley. A number of overgrown dumps are remaining south of the viaduct.
