NEHL - Horsley Pit was located just off Oatens Bank north of Horsley, Northumberland. It was working before the 1860s, though after this point had expanded to form the terminus of a waggonway southwards towards High Barns.

There was two ancillary buildings - one along the road made of brick or stone as it featured an Ordnance Survey benchmark, and another much smaller building which was likely an outhouse or the like.

The shaft and part of the waggonway were still extant into the 1940s.
