This mine was already active in the early 18th century, and was operated intermittently until 1891. It worked a number of ENE-trending lodes in metamorphosed killas overlying the west flank of the Carn Marth granite. The workings are located under Redruth town; the shafts are built over and most of the many small mines that were included in its sett cannot be identified today. Coordinates given are those of the stepped chimney near Engine and Sump shafts, which was erected around 1824.

The lodes are intersected by two NW-trending cross-courses, about 100 fms apart. The western cross-course, which is said to carry cobalt ores, has been traced southwards to Wheal Sparnon. The eastern cross-course (or, Braggs cross-course) presumably carries uranium ores.

During its last working period, from 1854 to 1891, the mine produced 1,090 tons of 5.5% copper ore, 7,700 tons of black tin, and, together with Wheal Sparnon, 974 tons of arsenic. It was by far the largest tin producer in the area.
