The mine was developed on 3 parallel 'flat' lodes which dip at an angle of approximately 30deg to the south-east. The main lode currently accessible has been stoped away to form one huge cavern 6 to 20 feet in height and around 200 feet deep and 200feet wide along the strike of the lode. This ends in the lake shown in the photos. The other lodes lie 1 above and 1 below this, separated in places by as little as 4 feet of roof or floor from main lode. In a side adit off main lode there are 2 ore chutes from the lode above. The floor of the stope is comprised of rubble, a mix of killas country rock and magnetite bearing iron ore. The magnetite crystals range from microscopic to about 3mm along the edge.
The entrance to the early adit is obscured and barred, that of the lower adit (SX773772) can be seen from the public footpath, though this is also heavily barred and provides drainage from the mine. Oct 2003.
