Cornish Mines Underground 4: the next set of images show some of the mines accessible around the St Agnes area.
The images below were taken at Cligga Head Wolframite Mine in the late 1990’s. Wolframite was the main source of Tungsten which was widely used in the manufacture of munitions. The surface area of the site was the location for the British and Colonial Explosives factory which opened in 1893. This was eventually purchased by the Nobel Explosive Company, the site was in production until 1909 when a drop in metal prices closed many of the neighbouring mines.
The Cligga Head Mine opened in 1938 and was closed on the completion of the Second World War in 1945. In the 1960’s Geevor Mine in collaboration with other mining companies, re-commenced underground works with active exploration and diamond drilling. No great results were forthcoming and in 1964 Geevor Mine decided to expand their own sett with the re-entry of the Levant Mine workings, so the site was again abandoned. More work on the site was planned for the 1980’s, however the huge drop in the price of Tin due to the market collapse halted this project. The story here is not over yet, with rising Tin prices I believe there has been renewed interest in the site, the future, who knows.
