The St Peters Vein was discovered in 1902 during the driving of Blackett Level. Thought at the time, to be the continuation of Swinhope Vein, the deposit was worked initially from Blackett Level by W B Lead then from the St Peters Shaft by the Weardale Lead Co. The productive ground was confined to the Great Limestone and there are extensive flats at this horizon at the Western end of the mine.
The vein consists of galena in a gangue of fluorite. Galena values decreased with depth and in the four fathom limestone sphalerite was said to predominate.
Recently worked for specimens by Dave Hacker and Northern Minerals.
