The dramatic coastline of Cornwall in southwest England is dotted with chimney stacks left over from its long-gone mining industry.
But out to sea lies another legacy — thousands of tons of tin, waiting to be mined.
“There’s 22,000 tons of tin there,” said Mike Proudfoot, chief executive of the mining firm Marine Minerals, looking out over the stunning north Cornish coast and stretching a hand over the deep blue expanse of the Celtic Sea.
The whole of the north coast of Cornwall is massively important for tourism so anything that would damage the tourism industry has to be taken really seriously.
