Tin, copper and arsenic. Last active in 1926 when copper was precipitated from the run off from the dumps.
Ref: Richardson P.H.G. (1991) Mines of Dartmoor & the Taymar Valley after 1913, Devon Books, Tiverton.
A very extensive site, from the crooked chimney on the hilltop at the top of the arsenic flue to the rock dumps beside the river. The majority of remaining buildings are on the hillside just above the red sand dumps, which are said to contain 124 000 tons of material and do seem to go on forever. The remains of a small arsenic labyrinth is located directly below these dumps. Further on down towards the river are more dumps now heavily overgrown, a massive set of lime kilns and many other buildings. This part of the sett is separated from the main rock dumps down towards the old brickworks chimney by a small steam draining the tailings which contains many pebbles coated with bright blue/green copper mineral precipitates (Oct 2004).
