The Wethered shaft (named after Oliver Wethered, one of the founders of the mine) was begun in 1909 and initial development occurred around it. By 1919, the works were moving west toward the coastline and the Victory shaft (named to celebrate the end of the First World War) was sunk about 540 metres to the north-west. The mine suspended operations in 1921 and again for 12 months during the tin crisis in 1930 that permanently closed many other Cornish mines. In 1944 working through Wethered shaft was discontinued, but the Victory shaft continued in use.
