Test drilling has started at the old South Crofty tin mine at Pool - after a long delay caused by the coronavirus crisis.
Crofty was Cornwall's last working mine before it closed in 1998.
The site is operated by Strongbow Exploration - which plans to start by drilling a shaft a kilometre deep to try to discover how much tin is still there.
The tin mineralisation that was mined up until 1998 continues beneath the old workings and we believe continues a long way past the old workings, and we think the mine could have a long life again.
Footage shows a wall of mud crashing into a lake at a jade mine in Myanmar, killing more than 160.
