The face of No. 3 level is now in a favorable position for developments, 
and should be entended until the north end of the dyke-bulge is reached. 
Each favorable-looking reef intersected should have levels driven to both 
the east and west walls of the dyke. 
The latter portion of No. 3 adit level is on the foot-wall side of Ross’ 
cross-reef, while the greater portion of the gold obtained in the upper levels 
came from the reefs on the hanging wall side of this reef. The extension of a 
level north-west on the hanging wall of Ross’s Reef would be useful work. 
The mine workings are well situated for prospecting and economic 
development; capital and good management should again place it upon 
the gold-producing list.

THE STAR AND THOMSON GOLD MINE, ABERFELDY. 
By A. M. Hoivitt, Field Geologist. 
The Star and Thomson gold mine is situated south of Aberfeldy township 
on the western slope of the Divide between the Thomson and Aberfeldy 
rivers, and between Barefoot and Lone Star gullies. 
The reef occurs in Silurian sandstone and slate, and has been worked 
for a number of years with varying success by several adits, the two lowest of 
which are dealt with in this report. A survey was made by Mr. C. M. Lyons, of 
the Long Tunnel mine, Walhalla, but the plan has not been published. 
The upper adit (middle tunnel of Lyons’ survey) was driven on a bearing 
of E. 37° N., and cut the reef at 352 feet. The north drive was put in 560 
feet, and the south drive 20 feet. A shoot known as the “ Thomson ” is 
reported to have been stoped opposite the adit-level for about 60 feet long 
by 100 feet to the surface. In the north drive no gold was seen past this 
shoot, and the reef was irregular in strike, but at 224 feet the reef became 
more regular, and the quartz more solid, being in places 1 ft. 6 in. wide, with 
prospects of gold. At 312 feet a cross-cut put in west for a distance of 78 
feet shows beds dipping 40° E., but changing to nearly vertical at the end 
of the cross-cut where a narrow bedded quartz vein is seen striking N. 35° 
W. As shown in the section of this cross-cut, there is a strong slide dipping 
to the east and pitching 15° N., which would carry it below the winze. On 
this slide the beds are bent over on both sides, indicating a movement to 
the east below it. This easterly movement may have something to do with 
the main reef being found so much further to the east than was expected 
in the bottom adit-level north, below and opposite Reilly’s winze. Reilly’s 
winze was sunk at a point 87 feet north of the cross-cut as shown on the plan, 
and Anderson’s rise was put up a few feet south of the winze. Another rise 
known as the “ No. 1 ” is close to the cross-cut. 
Reilly’s winze has an underlay of 65° E. for 35 feet, but at 51 feet the 
reef was vertical. A crushing of 4 tons yielded 18 dwt. per ton, but this 
gold-bearing stone was lost at 15 feet down' the winze. 
Above the level the reef ranged from vertical to 65° E. for a distance of 
15 feet, then 60° E. for another 15 feet, and then the payable stone came 
in with a westerly dip. From here upwards to the surface, a distance of 
about 400 feet, the reef has been stoped out, but several blanks occurred 
where the reef rolled over from east to west, the western dipping portions 
being payable and fairly large, the eastern dipping poor and narrow. Some
