A uranium mine.
The mine began life working ochre at the surface and iron ore, principally magnetite at depth. Some tin was also raised.
Uranium ores were also discovered close to the surface, principally hydrated minerals such as Torbernite, known locally as 'Green Jim'.
Pitchblende was discovered at greater depth and in later years became the mainstay of the mine until closure in 1930.
Whilst uranium ores had been found in other Cornish mines, occurrence was sporadic. South Terras was unique in Cornwall in that a lode of some 250 fathoms length (457.2m) was found with uranium derivatives being the principal ores (taken from the Journal of the Royal Institution of Cornwall Vol. 1, 1993).
The whole site is measurably radioactive. The house remained occupied well into the 21st century but has been abandoned as of 2021. If the normal background radiation is 10 to 12 counts/second, across the South Terras site and even out in the road the counts wander from 50 to 200 counts/second. However, in places counts rise to 500/s and at the head of the new adit shaft contaminated water is evidently seeping out as counts across wide parts of the sunken floor exceed 2000/second.
Note on the mineral list: Xanthiosite, aerugite, and bismutoferrite have been removed from the list due to the high probability of fraudulent recording of discovery by A.W.G. Kingsbury.
There are several probable uranium species awaiting analytical confirmation from material collected on a Russell Society visit made in 2018. Initial quantative analysis indicate a combination of elements which do not completely conform to the species listed.
