The Carrock Mine (Caldbeck Fells, Lake District) was redeveloped by the Government sponsered Non-ferrous Metals Development Company using Canadian Army engineers. There are some details and a cracking photo in MP Cooper and CJ Stanley's "Minerals of the English Lake District - Caldbeck Fells" published by the Natural History Museum Pg 46 "The Government financed Non-ferrous Metals Development Company re-opened the mine in 1942 using Canadian Army engineers to develop the property. A new low level adit was driven [NY 3225 3295] and a goood deal of exploratory driving done on the Harding and Smith veins. This enabled the Ministry to prove the ore reserves, but no stoping was done. To help in the search for scheelite a portable UV prosepcting lamp was specially delivered by the General Electric Compnay; with the batteries it weighed nearly 74 lbs (Rabone 1945). By 1943 the tungsten supply position had improved and the Government decided that further work was not necessary" Rabone, P 1945 - Transactions of Institute of Mining and Metallurgy, 54 231-241, 256.
