In the present north face 6 inches of magpie quartz on the hanging wall 
side dips to the west across the strata. The footwall some feet away to 
the east carries a few inches of puggy reef. The strike of the reef is N. 21° 
W. to N. 32° W. The south drive has been put in 96 feet exposing near 
the adit nice bodies of magpie quartz up to 3 feet wide, and having colours 
of gold in prospects, but at the present south face, only thread quartz veins 
and crushed slate are exposed. This south drive was put in to search 
for the “ Thomson ” shoot worked in the upper adit level. 
At about 800 feet from the mouth of the adit some gold-bearing quartz 
spurs were followed. They developed into a bedded vein, and were left 
after a little driving, as the prospects were unfavorable. 
At about 780 feet from the adit mouth a reef formation of a promising 
nature occurred, and was driven on south for 42 feet, the first 20 feet being on 
a small block 20 feet by 12 feet carrying nice gold. This was risen on, but it 
cut out at 3 feet above the level, prospects of gold continuing, but no quartz. 
The south face shows thread veins dipping 75° W. in strata dipping 78° E. 
The north level was driven on fairly solid quartz up to 1 foot wide, 
which expands to 2 feet with spurs at 80 feet in, carrying fair prospects of 
gold on the hanging wall and footwall, with the central portion barren. The 
present north face shows more regular veins on a good foot-wall dipping 
75° E. in strata dipping 70° E., the difference in dip in the north and south 
faces being due to a small roll in the reef. 
The strata in the main bottom adit are hard sandstones, quartzites, and 
narrow beds of slate. A large banded quartz and slate formation 27 feet 
wide and dipping 70° E. was cut at a distance of 228 feet from the mouth 
of the adit. This quartz formation had a diorite dyke on the hanging wall, 
but was very poor in gold contents, an assay of pyrites concentrates from 
it yielding only 2 dwt. per ton. 
General Conclusions. 
Beyond the large formation six faults were cut, and at most of them a 
distinct change in the angle of dip of the beds was noted. Eastern dipping 
beds predominate, but a wide series of beds ranging in dip from vertical to 
70° W. are seen within 100 feet of the 780-ft. reef line. 
Between the 780-ft. and 1,050-ft. reefs the beds are more regular, and 
are not so faulted and disturbed, being on the whole similar to the strata 
in the upper adit. This bears out the opinion that the 1,050-ft. reef is the 
main Star and Thomson reef as worked above in the upper adit-levels. Its 
poverty at the bottom level may be attributed to the reef being driven on 
in a blank similar to many which have already occurred in this mine on the 
rolls, the only difference being that usually the blank rolls dip east, whereas 
this is a western-dipping blank. Better stone may be expected above the roll. 
It is evident that between Reilly’s winze in the upper workings and the 
bottom main level there is at least one big roll and possibly several smaller ones. 
A rise to connect with Reilly’s winze as recommended by the mine 
manager would be advisable, as the rolls could be more easily followed, 
and any payable quartz between them proved more quickly than by driving 
north to catch the rolls on their northern pitch. 
The 780-ft. reef is apparently a separate line, and warrants further develop¬ 
ment north. This reef, on account of its strike and dip should be found a 
little to the west of the upper adit mouth, the middle tunnel of Lyons’ survey. 
It would probably be found in eastern dipping beds, and would be subject, 
to the usual rolls and blanks. The mine has its own ten-head battery, and 
"is most suitably situated from a mining point of view.
