Stanhopeburn Mine was a large lead mining complex dating back to at least 1830. The mining of galena from the Red Vein ended here in 1875, but fluorspar extraction continued until the mine closed in 1982. The flues on the hillside above the mine were associated with a lead smelt mill once situated on the site. These channelled and condensed toxic fumes released by the smelting process. Remaining fumes were carried to a chimney high on the hillside.
