Great Rock Mine is a disused micaceous haematite mine about 3 km north of the town of Bovey Tracey in Devon, England. It was worked from the nineteenth century until 1969,[1] and was the last active mine in the Dartmoor National Park area.[2]
At its most active during the 1940s, the mine produced 2,500 tons of micaceous haematite per year.[3] The mineral was an important ingredient in the rust-resistant paint used on Royal Navy ships and on bridges, including the Royal Albert Bridge and the Sydney Harbour Bridge.[1]
