Site Description: Coastal mine which is now operating as a visitor attraction. Tin and copper have been mined from the general area of Geevor since the late 18th century. Wethered Shaft began in 1909, by 1919 work moved west towards the coast and Victory Shaft was sunk. Operations were suspended in 1921 and again in 1930 due to falling tin prices. In 1944 Victory Shaft continued to be used. During the 1960s there was much underground exploration including the undersea workings of Levant mine (which closed in 1930). The mine closed in 1990 and the mine was left to flood from 1991.

Engine Shaft Hinds Engine Shaft Kistles Shaft Harveys Shaft Bassets Shaft

Site Description: Dines: Amalgamated with Wheal Basset. The mines in this group lie in the valley between Carnmenellis and Carn Brea. North Wheal Basset was originally a copper mine, it produced over 30,000 tons of copper ore between 1846 and 1869. In 1854 a large ore deposit of copper was discovered and development and shaft deepening took place to access it. It was discovered in 1857 that the potential ore reserves had been seriously overestimated. North Wheal Basset mine was comparatively short-lived. Wheal Uny mine was opened at the end of the 19th century, but was only operational for a short period. It closed in 1893. Wheal Buller was one of the greatest copper mines in Cornwall. Wheal Buller produced some 242,000 tons of copper in its working life.A new shaft was sunk in summer 1856 known as Kistler's (or Kistle's) Shaft but production continued to fall. The mine struggled on into the 1870's but the position of the mine was unsustainable and the mine equipment was sold off in 1875. Tresavean Mine was active in the middle of the 18th Century and was reopened in the early 19th Century. It became an important copper producer in 1829; it was worked until 1870. Mining recommenced in 1910 but the mine closed in 1928 due to the fall in tin values. Trounson: The Great Flat Lode was virtually exhausted in the Basset group with the exception of a short ore-shoot near Lyle’s Shaft. Wheal Uny is worthy of

further investigation. Safeguarding

Site Description: Dines: Pendarves dates back to 1854, as a group of mines including Wheal Nelson, West Condurrow, Tryphena, Tolcarne and South Tolcarne. Worked in the 1840's, again producing a small amount of copper ore. The mine extracted ore from one chief lode known unsurprisingly as Main Lode. It worked from seven shafts: Plantation, Bennetts', Pendarves, Newton, Vivian's, Tolcarne and Roaring Water Shafts. In 1967/68, Simms shaft was sunk to a depth of 260m. Some limited mining was carried out until 1973, when the mine was purchased by a subsidiary of South Crofty Ltd. Production was scaled up to 40,000 tons of ore per year until 1981. The output declined and in 1984 the mine had run out of developed ore reserves and had to close.

M18 South Crofty Grid reference: SW664 410 Mineral type: Tin, copper Planning Status: Active (not currently working) Site Description: Large, active underground tin mine covering much of Pool, although not currently producing

metals. Several shafts and associated infrastructure within the mineral planning permission area. Extant planning permission for processing plant, yet to be implemented. South Crofty Mine is located in Pool, mid-way between Camborne and Redruth in west Cornwall. Mining in this area is thought to date back to the late 1590s, only becoming known as South Wheal Crofty in 1854. Typical of early mines in the area, working commenced as a shallow tin and copper prospects, turning to the deep tin zone from the 1860s onwards. After the 1890s, the mine acquired other setts as the surrounding mines closed, including New Cook's Kitchen Mine, Tincroft, Carn Brea, North Roskear, South Roskear and Dolcoath Mines. The mine effectively ceased to operate in 1998. In June 2001, Baseresult Holdings Ltd (BHL) acquired South Crofty and the associated mine plant and developed a tunnel from the Tuckingmill Decline to connect to New Cooks Kitchen Shaft and Old Engine Shaft. The former to be used as a service shaft and the latter for secondary egress. In November 2007, Western United Mines (WUM) was launched following a joint venture between BHL and Cassiterite LP. In December 2010, WUM became a wholly owned subsidiary of Cornish Minerals Limited (CML). In 2013 WUM announced that they had entered into administration and that the mine was placed under ‘care and maintenance’

M26 Wheal Vor and Wheal Metal

Grid reference: SW626 304 Mineral type: Tin Planning Status: No planning permission Site area: N/A Shafts: Borlase Shaft, Boundary Shaft, Engine Shaft, Metal Shaft, Trelawney Shaft,

Iveys Shaft Site Description: Wheal Vor and Wheal Metal was a metalliferous mine about 2 miles (3.2 km)

north west of Helston and 1 mile (1.6 km) north of the village of Breage. Little remains of the extensive workings of 15 or so engines said by the historian Joseph Y. Watson in his 'A Compendium of British Mining' to 'resemble a small town'. Wheal Vor had its heyday between 1812 and 1848 and was said at the time to 'contain the richest tin lode in all of Cornwall'. Other mines working the extended sett included Wheal Metal. Wheal Vor closed in 1848 to 1853 and reopened in 1858. In 1870 Ivey's shaft at Wheal Metal reached a depth of 227 fathoms but had problems with water, a shaft collapse, drop in ore grade combined with a fall in tin prices. This resulted in the ceasing of all production from the mines to the east of Edward's Shaft in 1874. Dines: Attempts made to open both Carleen and Wheal Vor between 1906 and 1915 were not successful, largely owing to water difficulties. Trounson: In 1860 the old mine (Wheal Vor) was abandoned and operations continued at Wheal Metal which was becoming very productive. There are about 1,500ft of almost entirely unexplored ground between Wheal Vor and Wheal Metal. Wheal Metal is probably worked out. A prospecting company was formed in 1961 but difficulties arose. It is thought that ore remains.
