Great Condurrow Mine
The post-war slump in 1921 saw the closure of Wheal Grenville which resulted in the flooding of King Edward Mine. Mining operations were transferred, albeit on a far smaller scale, to the adjacent Great Condurrow Mine, to the north, a small portion of which was above the natural drainage level. This underground facility is still used by the Camborne School of Mines.
Over the years as mining education became more technical, the tin dressing machinery was replaced with pilot scale equipment. In 1974 the pilot plant was transferred to the new School of Mines Trevenson Campus at Pool and the 'mill complex' part of the site which included the mill, stamps, mill engine house, boiler house and the calciner had been largely stripped of their equipment and were no longer required for educational purposes.
