This mine worked the Perran Iron Lode for about 300 yards east of the Treamble Mine. The grid reference marks the site of Engine Shaft. Hamilton Jenkin notes that the engine house still standing there in 1953 was wantonly destroyed in 1956. Today, no trace of the workings is left.

Between 1858 and 1880, the mine produced 10,826 tons of iron ore, 11,639 tons of zinc ore, 198 tons of 75% lead ore and 600 oz of silver.
