At the 1,108-feet level and 290 feet south-east, then 80 feet south-west, 
a large quartz reef, 100 feet thick, was struck. This was followed south¬ 
ward for 800 feet, where it thinned out to nothing, the channel or track 
still continuing. On the western side of this reef a dyke runs the whole 
way. This dyke is from a few inches to ai few feet thick. It continues 
southward from the termination of the reef. Only a trace of gold exists 
in this massive quartz reef. At the 1,750-feet level the rocks are Hark 
bluish-grey in colour, and unaltered. A cross-cut w<as driven south-east 
from this shaft, so the manager informs me, and a well-defined reef, 6 
feet thick, with only traces of gold, was cut. 
At the 1,6'00-feet level there is a blind plat. The 1,500-feet level is 
driven right through to the Black Horse shaft. 
The Egerton workings extend below the Rose and Sister Rose workings, 
but no 1 continuation of the rich shallow shoots of gold was found. 
Heathcotian Rocks. 
An outcrop of grey and reddish cherty beds, through which minute 
quartz veins ramify in a remarkable manner, occurs on a small hill 10 
chains east of the Quarry Reef. The hill is about 7 chains from north to 
south, and nearly as wide. Ordovician rocks appear to surround it. From 
its lithological aspect it may safely be referred to the Heathcote series of 
beds. Possibly the presence of this inlier is connected with the system of 
faults disclosed in the Egerton mine. 
Older Cainozoic (Tertiary). 
About 2 miles in a north-easterly direction from Egerton is Surface Hill, 
on the top of a ridge. An outcrop of auriferous gravel has been sluiced 
here over an area of nearly two acres. The miners have sluiced off about 
2 feet of wash-dirt or gravel. This rests on and is intercalated with re¬ 
al ranged granitic detritus; to what depth it continues is uncertain. A 
shaft sunk near the top of the surfacing for a few feet leaves the matter 
in doubt. In the gully at the lower end of the surfacing a shaft has been 
sunk into glacial conglomerate. This locaiitv deserves further prospecting, 
as the ridge for some distance is Tertiary rock, and other outliers of the 
drift may be expected in these hills. Where the Tertiary gravel has been 
removed, alluvial gold should be found in the recent gullies.

By E. /. Dunn , F.G.S., Director, Geological Survey. 
At Meredith a very wide-spread series of auriferous gravels of Caino¬ 
zoic (Tertiary) age exists. It appears to belong to the older group, judging 
by the highly-rounded character of the pebbles. Formerly this gravel was 
profitably worked by means of adits for a length of 3 miles along the 
course of the Moorabool River. The outlet has never been satisfactorily
