a small lode following the bedding. The average 
dip of the eastern lode in the level and st opes is 53° 
W. At 310 feet south of main cross-cut a westerly 
cross-cut reveals the extension of the roll exposed 
nearer the shaft ; at 30 feet from the eastern 
reef is the main or western reef. Stoping above 
this point shows the reef to have rolled on the 
monocline (Fig. 2), stopes up to 12 feet in width

being visible at 10 feet to 20 feet above the drive. A diorite dyke pitching 
south shows in the stopes at 25 feet above the intersection of the western 
reef by the cross-cut. This dyke is on the floor of the drive south at 420 feet 
from the shaft. Stoping below the dyke extends downwards on the western 
reef to the level below (325 ft.) from 7Q feet north of the cross-cut southwards, 
but little work over the dyke has been done north of the cross-cut, the reef 
above the dyke in this part being small. At 40 feet south from the cross-cut 
a rise meets the flat dyke at 16 feet above the level and from this point upwards 
an interlaminated series of dykes exists. These dykes form part of the 
horizontal dyke and in places almost entirely replace the lode (Figs. 3-7),
