The Cornish tin and copper mines date back to the 16th century but minerals have been found and dug out of the ground here for over 4000 years. The coastal mines are accessed from the cliff face at a point level with the seam of minerals several meters below the surface. In the 20th century they went deeper and spread further to get to more remote minerals eventually reaching under the sea. I met a miner who worked in these deep mines and told me that on stormy nights they would hear rocks grinding over the seabed above.
Inside the mines copper minerals seep through cracks in the granite and collect into blue green liquid pools slowly forming crusts of crystal like copper carbonates, in some places the colour streams down the cliff face marking the site of the mine within.
