One thing is certain, it has to come out at some point. My bet is that it would be easier to flash up Geevor than start a fresh mine at Killifreth/etc.
Anyway........
Just out of interest during the last reincarnation about 40 years ago, I believe the last shaft in Cornwall was sunk. And that was the first for 40 years.
Pendarves Mine
Old workings known as Pendarves Consols, Pendarves United and Tryphena occur between Pendarves [646 379 and Beacon [657 393]. Cornish Explorations began re-examining this area in 1962 and a drilling programme commenced in 1963 with limited examination of old workings. Various mining companies financed the venture includinc Bibis Yukon, Guggenheim Exploration Co. Ltd, Pacific Tin Consolidated Corporation and Tehidy Minerals Ltd. Union Corporation (UK) Ltd joined the consortium in 1966 to manage the project. The consortium, under the name of Camborne Tin Limited, drilled vertical boreholes on the site of the proposed Pendarves Shaft upon which work was begun in late 1967. The shaft, first to be sunk in Cornwall for 40 years, was completed to 260m and commissioned in 1969. In 1970 the company managing the mine became Camborne Mines Ltd and started underground exploration by crosscutting north-west and south-east to Harriet and Tryphena lodes respectively. A decision to commence production was made and in 1971 Straus Exploration Incor¬porated obtained additional finance for this purpose.
Also in 1971, the Cornish Tin Smelting Company Ltd was purchased in order to process the Pendarves ore at their Roscroggan mill. 432 tonnes of ore were produced but operations were suspended in 1972 and the mine was taken over by Great Western ores Ltd, a subsidiary of South Crofty (St Piran Ltd) in 1973. The shaft was deepened to 6-level in 1976 and further exploration of Harriet and Tryphena lodes carried out. By 1973 the shaft had been sunk to 7-level and exploration of Tryphena Lode yielded poor results. A drilling programme was initiated in the same year to ex¬amine the Great Flat Lode in the area west of South Tolcarne Mine [656 386], and possible extensions of Dolcoath South lodes. As a result of the international tin crisis of 1985/6 the mine was closed and placed on care and maintenance on 31 July 1986.
The past is a foreign country: they do things differently there.
