There are more than a dozen individual mines in the area of the Caldbeck Fells, which were an important source of copper, lead, arsenic, baryte and tungsten from the 16th-century up to the 1980s. The larger copper mines included Mexico Mine, Red Gill Mine, Roughton Gill Mine and Silver Gill Mine. Carrock Fell Mine was the last in the area to remain active and the only one to produce wolfram and scheelite in England outside Devon and Cornwall.
