New Cook's Kitchen Shaft headgear, South Crofty Mine, Carn Brea. Looking north-east, Cornwall. 

South Crofty Mine headgear. Ore is hoisted by self-dumping skip to the ore bin, left of the headgear, waste rock is fed into trucks and conveyed to the dump (left in foreground). The pump, made in 1873, has an unequal beam (10 feet stroke in the cylinder and 9 feet in the shaft) and plungers are 20 feet diameter down to 1,150 feet below the surface. The shaft is 340 fms. deep. The headgear of Robinson's Shaft (335 fms. deep) is seen on the right. The Carn Brea area embraces the northern slopes of the Carn Brea granite and the thermally metamorphosed killas and greenstone that overlie the northern flank. Practically all fissures in the area have yielded copper in the upper levels with tin beneath to a proved depth of 2,500 feet.  Date of image: 1945. BGS Old Photograph number A08101.
