This mine worked a series of NE-trending lodes within a transverse distance of about 30 fathoms in the area east of Camborne Beacon. Most development was done on Main lode, which was opened up by six shafts sunk over a distance of about 1,000 yards. Only little work was done on other lodes, which were mainly accessed through crosscuts from the workings on Main Lode. Much of the area is now built over, but there are still extensive dumps around Hope's Shaft and Pryce's Shaft, south of Condurrow Road. On the opposite side of the road, an engine house ruin survives at Woolf's Shaft.

From 1856 to 1865, the mine produced 30,495 tons of 6.5% copper ore, 2,030 tons of black tin, 6.5 tons of pyrite and 34 tons of arsenic. The mine was re-opened in 1911 as Condurrow Mines Ltd. and small amounts of black tin were raised, but operations ceased in 1913 just as the mine had been unwatered.
