Work has started to excavate Britain's first new metal mine for more than 40 years.
The Hemerdon tungsten mine on the edge of Dartmoor will cost about £130m to dig and is expected to start producing the metal in 2015.
The mine, near Plympton, will exploit the world's fourth-largest deposit of tungsten.
