Wheal Gorland mine
Wheal Gorland was worked from 1790 at Wheal Muttrall. Wheal Gorland worked a number of lodes through at least 12 shafts, these included Davey's shaft, Sims' shaft; Roberts shaft, Collins' shaft, Williams' shaft; Bawden's shaft, Muttrall shaft, Old Engine shaft; Green's shaft, Garby shaft, Paul's shaft and Davey's Footway shaft on the site. Wheal Gorland produced copper, tin, arsenic, wolfram and tungsten prior to its closure in July 1911. There was even some gold found. Production was erratic and like many Cornish mines it opened and closed depending on demand. Wheal Gorland became part of the St. Day United Group in 1852. In 1833 George Abbot wrote of Wheal Gorland in An Essay on the Mines of England: Their Importance as a Source of National Wealth "the mine had made profits of over £300,000 and produced 1,400 tons of ore per annum." It ranked third, in terms of profits, just behind Dolcoath and Consolidated Mines, in a table of Mines which had been continuously productive, and were still working profitably.
There is little to see apart from the area in which it was sited, now mostly a housing estate, between the B3298, Telegraph Hill, St. Day and Tolgullow. More information about Wheal Gorland and its immediate surroundings can be found at the Camborne School of Mines Virtual Museum website (www.projects.exeter.ac.uk/geomincentre/excur-gwennap). King Edward Mine museum has a 3D model of the under ground workings.
