These small fissures or footwall leaders are best developed where the 
reef channel cuts through slates, so the folds and their pitch are of import¬ 
ance as guides to the position of other slate beds on the reef channel.

The old workings of the sixties are now somewhat inaccessible, the 
deeper workings having been carried on from the old engine shaft at the 
north end of the chasm and the main engine shaft, 8 feet by 4 feet, in 
which the present company are working. The old shaft is stated to be 
150 feet deep, with a winze at that level for a further 45 feet. From 
this old shaft very rich ground was mined, and it was with the view of 
following certain rich veins dipping north that the main engine and pump¬ 
ing shaft was sunk. 
This main shaft was sunk by Messrs. Cato and Nicholls to 300 feet, 
with cross-cuts at the 150-ft., 200-ft., 250-ft., and 300-ft. levels. 
The old stopes at the 150-ft. and 200-ft. levels show that the reef forma¬ 
tion was mined for a width of 25 feet in places, narrowing to a few feet 
below the 200-ft. level. The present company are working from the main 
engine shaft (or Cato’s), and are driving at the 200-ft. level, and are in 
about 130 feet, or 90 feet north of the cross-course, v T hich is filled with 
dyke rocks, and past which no stoping has been done on the Prince of 
Wales shoot. Their north face at the 200-ft. level shows the footwall 
side of the reef formation, exposing 4 inches of slate, quartz, and pyrites, 
followed by 2 ft. 6 in. of quartz which is somewhat spurn 7 , and is asso¬ 
ciated wdth arsenical and iron pyrites. Several feet of the reef channel 
remains to be cut before the hanging wall is reached. In driving at this 
level the prospects have been poor. 
At the 250-ft. level they are driving south.; the quartz has widened 
from a few inches, where cut in the cross-cut, to 4 feet of spurs and 
mineralized laminated quartz on the hanging wall at a point 25 feet 
south, at the time of my inspection. Here the south face showed 2 feet
