At the western end of the open workings of Mochia, as well as smaller trench workings a large opencast quarry has been developed, 30-40 m wide at its deepest. It is between 10-40 m wide and at least 300 m along the strike. The method of extraction seems to have been to cut upwards and behind individual beds, causing them to fall to the quarry floor. Packs of rubble stone are to be found in two places, built up to provide access to the last working places. Hammer and ’gad’ or some form of pick seems to have been used.
