Description: Beadon Adit, Great Rock Mine, Hennock. Great Rock Micaceous Haematite Mine. Narrow lodes of micaceous haematite occur here in granite which is highly chloritized at the lode walls. The soft friable nature of the ore necessitates stoping of the ore for 6 ft. or so in advance of the stope breast so that the blasting necessary to remove the granite to give a working width to the stope does not disintegrate the ore. This method of working, shown in the picture, is known as 'hulking'.
