Graig Colliery & Brick Works (nprn 507795) is shown on the 1st ed county OS map, but had been abandoned by the time of the 2nd ed. The machine base comprise lines of 4+2 holding-down bolts in an area 3x1.5m, which sections of coursed stone walls on the uphill and downhill (N and S) sides. It may have been associated with the small brickworks shown on the OS map, of which there are no other visible traces, or it may have stood at the head of an inclined plane, which has also disappeared due to re-grading of the landscape immediately to the N.
