this wall, forming a good-sized vein in places ; but, so far, it has not been 
found profitable to work. This lode bears a resemblance to the lodes 
worked formerly to great advantage in the old Cornish Mine. 
400-foot Level. —At the shaft is centre-country (anticline}. The pitch 
of the beds is 16 deg. to the south. At 30 feet to the east of the shaft is 
a strong leg of quartz, 3 feet thick, between bedding planes, but it is 
not auriferous. It cut out on driving northward, but southward it should 
pitch with the country rocks. 
550-foot Level .— In this level centre-country (anticline) is found 
at 90 feet from the shaft in the western cross-cut. The centre- 
country is very distinct; the country rock is of favorable appear¬ 
ance, and in it is a small saddle-reef. A fault over this 
saddle-reef dips 55 deg. E. Twelve feet further west is a 
well-seamed leg of quartz, 9 inches thick, carrying a little gold. This 
dips 53 deg. W. In this western cross-cut, at 100 feet in, is a level 
running southward, and a rise above this level in centre-country, with a 
dyke, 1 ft. 4 in. thick, dipping to the west at 76 deg. At this point a 
little gold occurs in the quartz. At 200 feet in is a flat slide or fault, 
dipping westerly at 16 deg., and this fault appears to be the cause of the 
displacement of centre-country above it to the east, as shown by the 
centre-country in the shaft in both the 400 feet and 300 feet levels. At 
203 feet in is a dvke; at 227 feet is the face of the cross-cut. The whole 
of the country rock west of the centre country dips to the west; but at the 
end of the cross-cut the syncline appears to be close by. 
This mine has only reached a very moderate depth from the surface 
so far, and a, great deal of work has been expended in driving long levels, 
which have not yielded much result. The shaft appears to' be well placed 
as regards centre-country, and it would be good policy to continue it down¬ 
wards and to cross-cut to the east and west, especially towards the anti¬ 
cline and across it, so as to pick up evidences of both saddle reefs and 
11 legs.” Of course, spurry country must not be neglected, nor the cross¬ 
lodes that run nearly at right angles to the bedding. Winzes or rises 
should be kept in centre-country all the way, to discover all saddle-reefs, 
and, if properly placed, such winzes would be effective in ventilating the 
mine. 
The Cornish Line of Reef. 
About 100 feet to the west of the main axial line (centre-country) that 
passes through the waste-tip, west of the engine-shaft of the Cornish 
United mines; past the old brick chimney-stack further to the south there 
is another fold, a minor one, along which the centre-country is well 
marked. It appears to commence near the old shed at the mouth of the 
tunnel, and near the crushing plant it is traceable on the surface a little 
to the west of the old brick stack. It passes about half-a-chain to the 
east of the new main shaft, on which a winding plant is being erected. 
Further southward in the gully the fold is well marked, but it could not be 
traced still further to the south in the deep gully, where a prominent saddle- 
reef accompanies centre-country on another minor fold. This would imply 
that the latter fold is a very minor one, ahd not nearly so important as 
the minor fold previously described. It is of interest that, along the 
course of this second minor fold, as well as along the first minor fold, 
alluvial and surface workings have been carried on right up to the centre- 
country, and that along centre-country on both folds quartz-mining has 
been carried on. In working these mines, it is necessary to keep these 
facts in view, so that centre-country may be well explored.
