This small mine has a recorded history spanning from 1792 to 1798, then from the early 1800s to 1818, and again from 1850 to 1855. Although known to have produced copper, tin, and silver ores, the only documented output is 1230 tons of copper ore. The silver ore was found in the form of capillary native silver.

The mine was situated where Engine (Red) lode, running east-west, intersected with a cross-course lode running north-south, potentially indicating the source of the silver. Silver mineralization associated with north-south cross-course faulting is not uncommon in Cornwall.

Unfortunately, the site was largely destroyed about 20-30 years ago. Specimens of adamite in the Natural History Museum, London, reportedly collected from this location between 1953-55 by Arthur Kingsbury (1906-68), are now considered ‘implausible’ and likely originated from Lavrion, Greece. This mine is one of several likely or definitively falsified Kingsbury localities.
