I have now brought up-to-date the survey of the Lady Nelson mine, 
St. Arnaud. Since my previous visit in March, the No. 8 level north has 
been extended 190 feet on the Black reef, the total length of the level 
now being 238 feet from the cross-cut. The country (crushed quartz, slate, 
and sandstone) passed through in this level is similar to that described in 
my previous report, and showed no encouraging feature until a point 150 
feet from the main cross-cut was reached. Here in the V-piece between the 
Black reef and a west-dipping wall diverging from it at an angle of about 
40 deg. in strike, a vein of quartz 6 inches to 10 inches wide was cut, 
showing gold. According to Mr. Cornelius, the manager, prospects from 
small pieces of this indicated the quartz to be payable. Subsequent tests, 
however, proved the gold to be confined to a very small pocket, and the 
surrounding quartz to be unpayable. This spot appears to be the south 
point of the shoot of quartz called at the surface the Sebastopol reef, and 
the occurrence of gold at this end of it must be considered an encouraging 
feature, as at the surface and in the workings from the Sebastopol shaft, 
the payable shoot of gold occurred in the northern portion of the mass, the 
southern part being practically barren. 
As the attached plan shows, the channel of the Black reef does not 
conform to the bedding of the country, but cuts across it at an angle of 
about 40 deg. Along several of the bedding planes passed through in the 
level on the Black reef, a small amount of' movement has taken place, 
causing the formation of thin pug seams and quartz on polished walls. 
Along two of the firmest of these walls drives have been put in northward 
from the level on the Black reef. The first (No. 1 on plan), which is 150 
feet from the main cross-cut is in 50 feet from the level, and forms approxi¬ 
mately the S.E. limit of the supposed Sebastopol shoot of stone. The 
second (No. 2 on plan) is at 220 feet from the main cross-cut, and, so far 
as it has been driven (25 feet) forms the western boundary of the shoot. 
The only work being done in the mine is on the first mentioned wall, which 
in the present face carries from 1 inch (in the back) to 4 inches (on the 
floor) of mineralized quartz. The distance between the two faces is 52 
feet, so that in reaching the northern portion of the shoot that amount of 
driving would be saved by abandoning the present working face and ex¬ 
tending the drive marked No. 2 on plan, in which there is a full face of 
lode matter.

I beg to report that to-day I inspected the work done in the Lady Nelson 
mine, since 13th November, 1909. The drive at 150 feet N. of the cross¬ 
cut at the No. 8 level has been extended 20 feet. The footwall of the 
reef channel continues well defined, but the western wall is somewhat 
irregular. The lode matter between the walls has widened to 2 ft. 
6 in. in the back and 2 feet in the floor, and carries an increased amount 
of mineral. A little water is oozing from the face, and the appearance 
of the ground exposed by the last firing out is a distinct improvement on 
any other portion of the reef opened up.
