The most extensive mine developed on the Perran Iron Lode. The lode was first worked by opencasts; then by shafts sunk to a depth of 145 mts at Roebucks shaft. In would appear from Dines (1956) that the ore shoots were confined between NNW transverse planes (?faults). The iron lode is intersected by a N-S lead lode, which has some development on it. The mine is known to have been active at times between 1828-86. The decomposition of pyrite in the mine is said to have been a problem. Due to the high temperatures and bad air it created.
Recorded output:
34000 tons of iron ore
760 tons of pyrite
180 tons of ochre
20000 tons of zinc ore
185 tons of copper ore
3 tons of lead ore
