156 feet and southwards for 80 feet. A little gold was obtained, but 
the quartz was not payable. From this level a winze was sunk 45 feet on 
the course of the “ leg.” The quartz on top gave about 3 dwts. of gold 
per ton, but value decreased lower down. The shoot pitches south about 
8 de s- 
At the 245-ft. level the cross-cut has been driven 89 feet to the west, 
Twelve feet west of the shaft centre country was cut, the arch being 
formed of slate; at 30 feet from the shaft sandstone dipping west is met 
with and continues to the end of the cross-cut, where a quartz reef (leg) 
5 inches thick, has been disclosed. The quartz is laminated, and contains 
much iron pyrites and a little gold. The east cross-cut has been driven 
79 feet to a small quartz reef (leg) 6 inches thick; levels have been driven 
north and south along this reef without disclosing payable stone. 
Immediately to the north of the shaft are Davis’ old workings, and 
others still further north. These are reported to have yielded rich ieturns 
in the past. The pitch of the country north of the shaft is southward, and 
it is doubtful if the workings in the shaft are sufficiently deep to cut the 
continuation of the shoots of gold formerly worked to the northwai'd. 
This shaft is being sunk on an anticline, and at the surface a strong 
dyke runs to the west of the shaft and can be traced at the surface for 
many chains north and south of it. In the Spring Gully mine characteristic 
saddle reef structure and well developed reefs occur. This mine will 
probably be of the same character, but it appears to be still higher up in 
the Castlemaine zone. It is not advisable to expend much labour in 
driving levels until reefs carrying gold of payable nature are found. 
Sinking the shaft and cross-cutting east and west is the work most necessary 
to be done.

THE ANNIE LAURIE MINE, TARADALE. 
By E. ]. Dunn , F.G.S., Director , Geological Survey. 
This mine is situate on the west bank of the Coliban River, about 1^ 
miles in a south-easterly direction from the Taradale railway station. 
The country rocks consist of sandstones and slates of grey colour, and 
appear to be the Castlemaine beds, but no fossils were observed. At the 
mine the beds are folded over an anticline and pitch north at from 15 deg. 
to 25 deg. From the south face of a slope a tunnel has been driven, and 
at 124 feet in the saddle reef is cut which showed on the surface above 
the tunnel mouth on the slope. From the end of the tunnnel a winze has been 
sunk on the east leg, which is 4 feet thick, and another winze is sun,k down 
the pitch of the saddle reef and just under it for 280 feet. The strike of 
the saddle reef is about N. 20 deg. W., and the dip of the east leg is 45 
deg. E. The pitch of the saddle reef is to the north at from 15 deg. to 
22 deg. At 56 feet vertically below the tunnel a level is driven southerly 
on the west leg. The laminated quartz is 1 ft. 6 in. thick, and a little 
gold is got in the stone near the end of the level. From the same level 
the east leg is driven on for 160 feet in a southerly direction. A shoot of 
auriferous stone 20 feet long is being worked here, but the quartz is not 
rich. 
From the same level there is a connexion with a small whip shaft sunk 
from the top of the hill. There is a five-head battery, &c., driven by 
steam. The gold from this mine is worth ^3 18s. per oz. So far this 
mine is in the prospecting stage; it has been shown that saddle reefs 
occur and that there are some shoots of gold in the reef.
