Wheal Metal is a tin mining sett in west Cornwall, England, UK. Whilst not as famous as neighbouring Wheal Vor, it was thus described by the Mining Journal in July 1885: " Truly this is a wonderful mine--probably the richest tin mine in the world." It also hosts a very remarkable engine house of the mid 19th century that once stood over Trelawney's shaft on Wheal Vor, and since the Wheal Vor area itself has no visible remains, this is the only large surviving engine house of this group of mines which accounted for over a quarter of Cornish tin production in the mid 19th century.
