Wheal Josiah Mine

Wheal Josiah Mine, Devon

Wheal Josiah (part of Devon Great
) is located just below the cottages of the same name and to the
east of the chimney. There are extensive rock dumps with plenty of arsenopyrite
(massive form) and siderite (1mm orange/brown crystals in vugs). This was the
location of the deepest shaft on the sett, sunk at the insistance of the Duke
of Bedford who hoped to prove tin at greater depths as has been found at Wheal
Phoenix. This however proved a costly failure and no tin was found.
