A relatively minor mine in economic terms, but with a long history, if intermittent, history.

The mine was working in the the 18th century, reference being made to a dispute with the nearby Wheal Ruby in 1758.

Worked in 1835 in conjunction with Wheal Ruby by the Wedron Royal Mining Company, the mine was pumped out again in 1855.

In 1865, the group was known as Garlidna United, but working ceased, said due to the inability of the shareholders to pay their "calls".

Further work was done on a new lode at Garlidna in the years 1912-16, but with little success.

Site visted February 2011 by B Millington, no signs of any of the old buildings, a recent owner of the land appears to have bulldozed and removed the majority of the tips and filled in the majority of the shafts. The area is heavily overgrown with furze, bracken and trees. Examination of what mine waste that is left consists of mainly granite impregnated with plentiful red earthy hematite, massive fine-grained hematite and some specular hematite. Also noted was white banded quartz with occasional banded amethyst. Also noted were rare stones containing poor malachite with chalcopyrite and pyrite.
