In 1930 the mine closed. Some miners continued working above adit level. The mine was de-watered in the mid-1930s in an attempt to reopen it. The effort was abandoned and the mine closed permanently in 1939. During this time, on Bal Lane a terrace of twenty-six houses were built for miners. The ruins at Great Work reveal a fraction of the mine's extent. In the photo the engine house on the far left is the Leeds shaft and is all that remains.
