NEHL - A medium scale working owned by the Earl of Durham could be found north of Cocken Cottage and Finchale Priory. This mine only operated for a few decades in the 19th century. It was connected via waggonway to the Lambton Railway and featured a number of buildings and a brick field to the south. By the 1890s it was disused. There was a pumping engine in Bowburn Wood which was likely connected.
