One of the most extensive and productive mines in Nenthead, the portal of the Horse Level being close to the Heritage Centre car park.
Several collapses along the level have recently been dug-out and stabilised by the mine exploration group NORPEX, to whom we should all be very grateful (and helpful?). Their activity has accessed an extensive area of workings in this lovely old mine.
Major veins worked in Cumbria include: Scaleburn Vein, Rampgill Vein, Rampgill Cross Vein, Smallcleugh Vein, and Middlecleugh Vein; and in Northumberland: Barneycraig Vein, Whitewood Vein and Bounder End Cross Vein.
Once over the county boundary the workings are part of Coalcleugh Mine, the two are in different ownership and though they have been worked at the same time they have never operated as one mine.

***********************************************************************

The mine was completely closed for many decades due to collapses in the Horse Level, but in 2006 some work was done and it became possible to access the Bounder End Cross Vein (also known as the Boundary Cross Vein).
In 2013 the Canadian mining company Minco sunk boreholes to discover the extent of zinc deposits beneath Nenthead. Test drilling could go on for several years, but the company believes that the village may be sited on huge deposits. The zinc is 150 metres below the surface, which was too deep to reach by old mining techniques.
