Mount Wellington Tin mine, two miles east of the village of St Day in Cornwall, in the United Kingdom, opened in 1976 and was the first new mine in the region in many years. With the fall of tin prices and the withdrawal of pumping subsidies, the mine finally closed in 1991. An attempt to revive the mine occurred when an individual tried to transform it into a visitor attraction, but his endeavour failed. The site was bought by Mount Wellington Mine Ltd in early 2007, who removed the remaining headgear stump, and have proceeded to renovate the site and turned it into a private, gated, business park. There are a number of tenants who operate exclusively in the renewable energy sector including Kensa Heat Pumps. History 1920s-30s During the 1920s, three brothers called Wellington worked the old Wheal Andrew lodes close to surface. The brothers were mining in a small way, working with primitive plant and operations, taking ore to a Cornish stamps down the valley to be treated for its tin content. Captain Josiah Paull, of the Mines and Metallurgical Club in London, reported that the ore the Wellingtons were breaking was yielding an average of 30 lb. of black tin per ton. The workings around the shaft they were working were crushed at a later date, putting the shaft out of action, and “being only ordinary Cornish miners”, the Wellingtons did not have the money to either open up the adit or put down another shaft. In 1935 Mount Wellington Ltd, backed by the British Non-ferrous Mining Corp Ltd, acquired the rights on United and Consolidated Mines, Wheal Clifford and Wheal Andrew. On 5 February shares in Mount Wellington Mine Ltd were advertised for sale. During the 1930s further shafts and mining buildings were built at Mount Wellington the mine acquired mining rights to the adjacent mines. However, by the end of the decade, milling was being suspended due to low tin prices, and it faced difficulties extracting the ore at sufficient quantities to show a profit. On 16 December 1939 work stopped at Mount Wellington Mine due to lack of finance. 1960s-70s In 1963 International Mine Services Ltd of Toronto became interested in the mineral potential of Cornwall. By 1967 exploratory drilling began at Mount Wellington Mine and by 1969 a contract to sink No.1 Wellington Shaft and erect buildings was awarded to Thyssen (Great Britain
