1,925 feet above sea-level. The quarry is 100 feet long, 60 feet wide, and 
from 20 to 40 feet deep. The rock is altered Silurian not far from its junction 
with the granite. It was broken down in a face and sent away bodily through 
a pass and by a tramway to the battery. The results are said to have been 
profitable, but as the ordinary amalgamation process alone was used to save 
the gold there must have been much loss. 
Just opposite the battery on the south side of the creek is a quarry, 
opened up and worked by Mr. F. Falks. It is about 100 feet long and from 
5 to 20 feet deep, and is said to have been payable. The ore consists of the 
country rock, which has been altered by the granite. Some portions of this 
rock have been altered to extremely hard, nearly black hornfels. The 
auriferous rock is about the same distance from the granite boundary as it 
is from the quarries on the Golden Mountain Mine. 
Tallangalook Sluicing Claim. 
About half-a-mile north of the township site a sluicing claim is at work 
in the bed of the Tallangalook Creek. The height is about 2,500 feet above 
sea-level. It has been at work for many years, but the old gutter has only 
lately been reached. The bedrock is decomposed granite of moderately 
coarse grain ; above this is about 1 foot of gravel, the pebbles being quartz, 
crystallized quartz, tourmaline, &c., very well rounded ; above this is drift 
material and loam, to a thickness of 40 to 50 feet. The gold is very fine, 
and a little cassiterite and some small completely rounded topazes and garnets 
are found in the concentrates. This old lead trends past the west side of 
the township, and probably continues down the valley of Dry Gully, along 
the course of which are extensive alluvial workings. The age of the lead 
at the sluicing claim appears to be Newer Pliocene, and on the west side 
and lower down the valley of Dry Gully there are Tertiary deposits. Dredg¬ 
ing operations are being conducted at the lower end of Dry Gully, and there 
is an extensive deposit of Tertiary age on the west side of the gully opposite 
the dredge. The road runs over this Tertiary ground, which appears to have 
been driven out. There is a difference of over 1,600 feet between the level 
of the Tertiary deposit at the head of Dry Gully and those at the bottom of 
the gully, near its junction with the Brankeet Creek. Details require to 
be worked out in this locality. 
About half-a-mile east of the railway station, along the main road, there 
are Tertiary rises skirting the flanks of the Silurian hills and traversing the 
Junction pre-emptive. The gutter of this Tertiary has been worked to a 
small extent, and along the main road, even the surface of the gravel has 
been washed for gold. In the gutter the gold is of high value, and is well 
rounded. In the gravel are well-worn pebbles of quartz, lydian stone, 
breccia of black silica, and angular fragments of grey rock. Some jasper 
and other siliceous rocks are also present as pebbles. The relations between 
the Tertiary deposits of Dry Gully and this, the Bonnie Doon Tertiary, 
require to be worked out. 
Bonnie Doon Mine, Bonnie Doon. 
About 1 mile east from Bonnie Doon, and on the extreme point of a spur 
of Silurian rock on the north side of Glen Creek, is the Bonnie Doon mine. 
The height above sea-level at this point is 925 feet. The beds strike N. 10° 
W., and dip 70° E. The reef strikes E. 35° N., and dips 85° N.W. It was
