Holman's test mine was opened in 1888 and originally used to test and showcase compressed air drills. In the 1920's, Camborne School of Mines began using the mine for teaching until 2017.
The part of the Carnmenellis granite in which this test mine is located does not host a great deal of interesting minerals, however, whilst mucking out after a blast in one of the main drives around 1990, a small amount of Fluorite associating with a few small Apatite crystals were found, although not of great quality or quantity.
2 valid minerals.
