Geevor Tin Mine
 |
Geevor Tin Mine was operational between 1911 and 1990. Tin and copper have been mined from the general area of Geevor since the late 18th century. In 1985 the International Tin Council failed and there was a dramatic fall in the price of the metal. The mine struggled on for a few years, but closed in 1990, and the pumps were switched off in May 1991 allowing the workings to flood. The mine is not geologically exhausted of tin, but it is exhausted of tin that is recoverable economically. During the 20th century Geevor drove over 85 miles of tunnels from which it produced around 50,000 tons of black tin and made a profit of over £7 million. On average over a million gallons of water, a quarter of which was sea-water, was pumped from the mine daily.
