THE LATEST exhibit at King Edward Mine Museum at Troon remembers a man killed in a rock fall underground in the early 20th century.
Captain Thomas Jenkin was 42 when he died in the incident at Basset Mines, Redruth on September 10, 1906.
The plaque put up in his honour at Mithian Church, which is now closed, was donated to KEM by the family.
Tony Brooks, from KEM, said the museum jumped at the chance of owning the plaque: "This is real social history and the mine where he died can be seen from KEM."
It was a Monday in September 1906, when Capt Jenkin and his assistant Cecil Thomas went down in the cage at Marriott's Shaft to the 230 fathom level, that is about 440 metres below the surface.
Accompanied by Capt William James jnr, they climbed upwards to survey another area, but were killed instantly at the 200 fathom level, when part of the roof collapsed.
Mr Brooks added: "It is a tragic story - one young man, Cecil Thomas, died on his first mining surveying job, plus Jenkin who had travelled the world mining, leaving a wife and five children, and William James, the general manager's son."
Capt William James jnr was 25 when he died and is buried at St Euny Church, Redruth.
Cecil Thomas, from St Blazey, spent two years at the Henderson Mining School before becoming Thomas Jenkin's assistant surveyor.
He died, aged 20, on his first underground assignment.
