The dues, l-18th are paid to the Duke of Cornwall. There is only one lode worked on. The depth of the mine is 43 fathoms. 55 men, 4 females, and 20 boys, employed on the works (in 1861). The water is pumped by a 26-inch cylinder engine. Purser, Mr. H. Rogers, Helston; manager, Captain John Burgan, Helston; agent on the mine, Captain Bennet Dunstan. The company are now working in a spirited manner, with good prospects of success. There is some copper-ore in the lode, but tin predominates'.
