Lock Map
Locality type:Vein


The southern extension of the Harding vein in Coomb Height was once called Coombside vein.

The vein was worked from several levels to the valley floor and was stoped to surface on both sides of Grainsgill.

According to Hitchen (1934), bismuth minerals were most common in the 'west band of the Harding vein'.
