Last worked 1914-20 and 1923-4 with Tavy Consols.
Ref: Richardson P.H.G. (1991) Mines of Dartmoor & the Taymar Valley after 1913, Devon Books, Tiverton.
The mine is on the western hillside of the Tavy Valley across from Virtuous Lady. Whim shaft lies on the river side of the disused railway, Gills Shaft was covered by the railway and West Shaft is further up the hillside.
Worked in the 1840s for copper producing around 40 tons of 8% ore, in the 1850s a rich pocket of tin was discovered and in the early 1900s is was reworked again for arsenic.
Most of the output seems to have come from the upper levels around Whim Shaft though this was sunk to a 30 fathom level and then on down 20 fathoms more to deep adit with a portal on the river bank.
The lode is thought to be an extension of that at Bedford Consols on the hillside above Gawton. The physical form and pattern of deposition of the arsenopyrite would tend to support this supposition. Anatase included in the arsenopyrite lode would tend to confirm this.
