One of the last deep tin mines in Cornwall, this mine closed in 1992 and has now been converted into a museum and tourist attraction. The Victory shaft and the mine buildings are situated on the site of the former North Levant Mine, which was incorporated with the Geevor sett in 1920. The original Geevor Mine sett lay about 250m further southeast (closer to Pendeen village).
An extensive history of the mine is recorded in “GEEVOR”, by Cyril Noall.
Tin and copper have been mined from the general area of Geevor since at least the late 1700s. It was originally a small enterprise known as Wheal an Giver, “a piece of ground occupied by goats”. The area was worked under the name of North Levant Mine until 1891 when it closed. During the 1880s there had been up to 176 workers at the mine, but in the ten years after North Levant's closure, the site saw only intermittent activity by a few miners.
The Wethered shaft (named for 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 northwest.
By the 1970s Geevor's sett covered an area of about 3 square miles (ca. 7.7 km²) and included Boscaswell Downs mine, Pendeen Consols, and Levant mine. 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, it is exhausted of tin that is recoverable economically.
From old maps, several veins and lodes were encountered:
Veins: Footwall vein, Hanging Wall vein, and Prospect East vein.
Lodes: Edwards Lode, Mundic Lode, Carn Lode, New Lode, North Pig Lode, Peath Lode, Pig Lode, Coronation Lode, Simms Lode, Prince of Wales Lode, Treglowns Lode, Stennack Lode, Whisky Lode, Savells Lode, Prospect B Lode, Grenfell Lode, North Lode, South Pig Lode, Jumbo Lode and Caunter Lode, as the major ones.
Note on the mineral list: Botallackite has not been reported from the Geevor lodes. All specimens reputedly found at Geevor mine came from the Levant workings (mostly from South lode), with which Geevor is connected underground.

Geochronology
Mineralization age: Phanerozoic : 290 ± 7 Ma to ~45 MaImportant note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
