Tony & Roger,
Bampfylde Mine in North Devon was the largest copper producer in the South West during the 19th century. Until recently there was no evidence of smelting on the site.
However, discoveries of slag last year, and subsequent C14 dating indicate a smelting date of mid 15th century. The charcoal for the C14 date was extracted from within the slag.
Probably time to rethink?
Kindest regards,
Trevor
