Built in 1897, this calciner was used to roast arsenic ore - check out the date above the archway. Arsenic gas was driven off by the heat and travelled towards the stack higher up the hill and through the labyrinth, or lambreth, where it condensed on the walls. See this link for a diagram of the Brunton roasting furnace with the revolving hearth upload.wikimedia.org/wikipedia/commons/a/af/Brunton_roasting_furnace.png

Worth climb to the cairn for the downhill section on the main access road. Then drop into single track round the back lanes of Carharrack. Sweet! :)

South Wheal Frances was originally a copper mine in the 1820s, before becoming a tin mine from the 1850s. The mine was active until 1918. The structures are relatively well preserved, including the remains of the engine house which contained an unusual inverted vertical beam engine.
