Great Wheal Charlotte

Great Wheal Charlotte, also known as Wheal Charlotte, is an abandoned copper and tin mine lying between St Agnes and Porthtowan in Cornwall, England. All that is left of the mine now is the wall and door arch of an engine house and an adjacent fenced-off mine shaft. The surviving wall is surrounded by rock debris and the extensive remains of spoil tips, mostly of bare rock fragments crisscrossed by paths that link the South West Coast Path with surrounding land owned by the National Trust. Predominantly a copper producer, in its heyday, in the 1830s, the mine extracted ore containing 7.25% copper. It may have partially closed around 1840. However, ore production was high in this year, and records of output extend at least to 1856, and possibly to 1863.
