The mine remained closed until 1942 when a tungsten shortage during World War II led to the Ministry of Supply re opening the mine for just over a year. Mining began again in the 1970s and continued until 1981. There are five mineral veins of importance at Carrock Fell; from west to east they are the Wilson, Smith, Harding, Waterfall and Emerson.
