A small copper mine on the Camel estuary, between Trewornan and Dinham hamlets. It was started around 1800 as Trewornan Mine and later worked as Wheal Sisters. The workings consist of an adit at the base of the cliff and a shaft on the cliff edge. Sir Arthur Russell, who erroneously referred to this mine as Dinham Mine, reported jamesonite fron the shaft dump. The grid reference marks the approximate position of the adit portal.

Around 1850, during its last period of working, the mine sold 33 tons of copper ore.
