A lead and copper mine, started in 1847 and initially worked in conjunction with Legossick Mine. The sett comprises a NS-trending main lode and a SW-trending caunter lode, which were opened up to a depth of 91 fms below surface (55 fms below adit) from a shaft located on the west slope of a narrow valley northeast of Carthew farm. The mine was abandoned in 1853 and reworked as St Issey Wheal Phoenix from 1862 until 1867.

As Carthew Consols, the mine produced 139 tons of 70% lead ore and 120 oz of silver between 1849 and 1852, and 205 tons of 6.5% copper ore between 1850 and 1851.
