Around 1845, there was activity at a site where surface erosion had uncovered four copper deposits running east to west and one containing silver and lead running north to south. This latter vein was believed to be connected to a lead-rich geological feature known as Devon Great Consols’ White Maria. However, this endeavor didn’t seem to be successful, as by 1848, equipment such as a rotary engine, water-wheel, and flat rods were advertised for sale in a mining publication. In 1851, the site was reopened under the name Devon Consols North, with promotional material highlighting the good condition of the previous engine shaft, which was 40 fathoms deep. Despite further investment, including the addition of two or possibly three new shafts, the mine ceased operations in 1854. At that point, the 22-inch steam engine and horse-powered whim were put up for auction. Despite its significant development, this mine is not mentioned in the works of Dines or Collins, two notable authorities on mining.
