Ai the No. 13 level, at a depth of about 1,270 feet, the cross-cut is 
driven west for 200 feet to the reef, which is 40 feet thick, consisting of 
quartz and country rock. There are five different veins of quartz in 
this thickness that are being worked. The footwall line is well marked, 
and coincides with the bedding. Strike N. 35 deg. W., dip 72 deg. W. 
The main shoot of auriferous quartz has been practically worked out 
to the No. 18 level. There still remains the portion of the shoot between 
the Nos. 18 and 19 levels, or 120 feet in depth, to stope out.

BROWNING’S LUCK, ST. ARNAUD. 
By E. J. Dunn, F.G.S., Director , Geological Survey. 
This mine is about lialf-a-mile south-west from the Lady Nelson 
mine. The shaft is sunk to a depth of 800 feet. The country rocks 
consist of slates and sandstones that have undergone some changes due to 
metamorphic action, and the reefs appear to conform with the beds in 
strike and to a certain extent in dip also. There are two reefs proved, 
the Little Reef and the Main Reef. To the north of this mine is the 
New Chum mine, in which a profitable shootjaf auriferous quartz pitching 
south was worked. The upper workings in the reef of this mine are 
said to have been profitable. The shoot from the New Chum does not 
appear to have been yet cut in this mine. 
At 600 feet from the surface the Little Reef is just on the west side 
of the shaft. There is no* eastern cross-cut at this level j the western 
cross-cut cuts the main reef at 70 feet from the shaft, and a level is 
driven north on this reef. At 200 feet from the cross-cut stopes have 
been worked up to the 500-ft. level. At 230 feet from the cross-cut a 
winze has been sunk to* the Soo-ft. level. At about 420 feet in, the 
quartz reef is 2 ft. 6 in. thick and the reef has been stoped overhead. 
Both the country and reef dip west. South of_ the cross-cut the level 
has been driven on the course of the main reef for 53 feet. The reef 
is 3 feet thick, but in the face it is small and broken. 
At the 800-ft. level a short cross-cut is driven eastward, and from the 
end of this a hole was drilled still further east for 1,401 feet. The 
beds dip west at about 80 deg. A west cross-cut cut the Little Reef at 
120 feet, and then the Main Reef at about 160 feet from the shaft. A 
level is driven northward on the course of the Main Reef, and at 250 
feet a winze is sunk to a depth of 60 feet below the 800-ft. level. At 
400 feet in. this level ends. Three inches of quartz shows in the 
face. This level is not extended far enough north to meet the New 
Chum shoot worked further to the north in the adjoining mine. Stopes 
for 30 feet high and for a length of about 100 feet have been taken out 
in this north level. The west cross-cut is altogether 160 feet long, but 
it does not cut the reefs at right angles.
