Having built its fortunes extracting and producing metal for export around the world, Cornwall is a town known for tin mining. But in recent years, the industry has all but disappeared with only shore based mining taking place in one or two sites. The impact on the economy is tangible and has even decimated previously prosperous towns. According to Coastline Surveys, a new and exciting project has been launched that will build on the town’s mining heritage with an ambitious proposal to recover tin deposits from the waters off the North Coast of Cornwall.
