Geevor Tin Mine

Geevor Tin Mine, formerly North Levant Mine is a tin mine in the far west of Cornwall, England, between the villages of Pendeen and Trewellard. It was operational between 1911 and 1990 during which time it produced about 50,000 tons of black tin. It is now a museum and heritage centre left as a living history of a working tin mine. The museum is an Anchor Point of ERIH, The European Route of Industrial Heritage. Since 2006, the mine has been part of the UNESCO World Heritage Site Cornwall and West Devon Mining Landscape.

History
at Geevor in 2026 Tin and copper have been mined from the general area of Geevor since the late 18th century. It was originally a small enterprise known as Wheal an Giver, "a piece of ground occupied by goats". During the 1880s as many as 176 workers were employed at the mine, but in the ten years after North Levant's closure the site saw only intermittent activity by a few miners. They leased the area and conducted more thorough prospecting, being encouraged enough to set up a company called Levant North (Wheal Geevor) in 1901. The Wethered shaft (named after Oliver Wethered, one of the founders of the mine) was begun in 1909 and initial development occurred around it. By 1919, the works were moving west toward the coastline and the Victory shaft (named to celebrate the end of the First World War) was sunk about 540 metres to the north-west. The mine suspended operations in 1921 and again for 12 months during the tin crisis in 1930 that permanently closed many other Cornish mines. In 1944 working through Wethered shaft was discontinued, but the Victory shaft continued in use. From the end of World War II until the early 1960s both Geevor and South Crofty found it hard to raise capital and to recruit skilled miners. Both mines took on Polish and Italian miners at this time. and at this time around 270 staff were employed by the mine. During the 1960s there was much underground exploration; this included extending into the undersea workings of the Levant mine that had closed in 1930, work that was complicated by a hole in the seabed that first had to be plugged before the workings could be drained. By the 1970s Geevor's sett covered an area of about three square miles and included Boscaswell Downs mine, Pendeen Consols and Levant mine. and the pumps were switched off in May 1991 allowing the workings to flood. at Geevor Tin Mine at Geevor Tin Mine ==Geology==
Geology
The mine's lodes were located in an outer zone of coarse-grained biotite granite of Carboniferous age, intruded into surrounding Devonian age "killas" - a series of metamorphosed sedimentary and volcanic rocks, visible to the north west of the mine around the cliffs. As the influence of the granitic emplacement increases toward the contact zone, the killas becomes spotted with cordierite, then mica-rich phyllites and finally at the contact, banded hornfels and tourmaline schist. The tin appears as cassiterite (with around 65-70% tin), within veins associated with quartz, tourmaline, metal sulphides and fluorite. The veins are predominantly in a north west - south east orientation and the cassiterite itself forms around 1% of the vein material. ==Tourist attraction==

Through the commitment of the local community and local bodies, notably Cornwall County Council and Pendeen Community Heritage, the site has remained accessible to the public. Geevor Tin Mine is now a museum and heritage centre, covering an area of which makes it the largest preserved tin mining site in Great Britain. It is an important part of the Cornwall and West Devon Mining Landscape and was recognised by UNESCO in 2006. It has been the subject of a £3.8 million improvement programme funded by the Heritage Lottery Fund, Objective One, Cornwall County Council and Penwith District Council. Geevor's new Hard Rock museum is part of the final stage of this improvement programme. The museum tells the story of tin mining in Cornwall and Geevor in particular, showing what happened on the surface and underground and what life was like for those who worked there, including oral history recordings. Visitors can also walk through the mine buildings to see the original machinery and there is a guided underground tour into Wheal Mexico, an 18th-century mine. The site has a souvenir shop and a cafe that overlooks the Atlantic Ocean. There are interactive activities e.g. panning for gold and gemstones. == Mineral Statistics ==
