Limestone quarrying continued into and beyond the 1960s, a relatively recent and large-scale development being the quarry serving the Blue Circle cement works near Eastgate, set up in the 1960s. This site has now been decommissioned and the major industry in Weardale is now cattle- and sheep-farming. Only one mine, the Rogerley Mine, is currently being prospected on a very small scale for mineral specimens.
