Mining is the process of getting materials out of the ground. We use all sorts of things that have been dug up, for building, making metals, burning for heat and power. We can’t live our modern lives without mining.
Mining is one of our oldest industries. As soon as people worked out how to make tools from metal the hunt was on for places on Earth where minerals and ores containing metals existed. Devon and Cornwall have a very long history of mining due to their unique geology.
Mining is one of the oldest industries on earth. For as long as humans have used metals and minerals there have been mines.
South West England and Wales were famous from the Bronze Age
onwards for the quality and amount of minerals and metals mined here. It’s likely tin and copper from Devon and Cornwall were exported across Europe from about 2000BC.
Wealth and access to tin and copper was probably one of the reasons the Romans wanted to invade Britain. This changed the history of Britain forever. By the medieval times tin was one of England’s main exports, along with lead and wool.
Demand for copper increased in the 18th century as the Royal Navy began sheathing its ships with copper to combat barnacle growth and shipworm. Competition from foreign mines forced closure of most copper mines in the 1860s.
Tin mining in Devon and Cornwall continued into the Twentieth Century, but eventually became uneconomic in competition with imported tin.
In recent years there has been increasing interest in mining in Devon and Cornwall, with mining resuming at Hemerdon mine near Plymouth for tungsten, and a new lithium mine in Cornwall opening.

There are guides to the best places to visit in Devon to look at the geology, what rocks can be seen and even a list of active quarries showing what rocks they are mining from each one. There’s a wealth of rock related information available here.
