This mine, which was also known as Wheal Maiden lies within the Camborne-Redruth-St Day mining district and is in Gwennap parish.
The mine is bounded on the south by Great Consolidated Mines, the actual boundary being the stream that flows through the valley that now contains the old tailings dams from the Mount Wellington Mine. On the north it adjoins the Poldice sett.
It is recorded that five lodes were present in the mine being Tremaynes Lode, Martyns Lode, North Lode, South Lode and an unnamed lode.
Whilst an exploration project was carried out in the early 1980's known as the 'Wheal Maid Decline', this was undertaken wholly within the Great Consolidated Mines sett and did not link with any of the Wheal Maid workings.
14 valid minerals.
