The country rocks are grev and yellow sandstone, slate, and mud¬ 
stone, with some black slates. The strike is about N. 25 deg. W. 
A strong quarts reef shows close to the mouth of a tunnel, and this 
has a general strike of about N. 25 deg. W., but it is faulted at 2 chains 
from the tunnel, and thrown westward (going S.) for about half-a-chain. 
About another chain southward it is again faulted in the same direction, 
but not so far. The reef is about 4 feet thick, but numerous spurs pene¬ 
trate the adjacent country rock. 
This reef appears to be about on the line of anticline, as the country 
to the E. of it dips E., and to the W. it dips T vV. A shaft has been 
sunk 70 feet, and a whim erected. The country here dips W., and con¬ 
sists of alternating thin beds of slate and sandstone of grey colour. The 
indicator is about 24 feet E. of the shaft. The pitch of the country is 
southward at 23 deg. At the bottom of the shaft a cross-cut east is ex¬ 
tended for 30 feet and then the level is driven southward. At 40 feet along 
this level a quartz vein J to 1 inch thick and dipping south at 70 deg. crosses 
the country. It was at a higher level where this vein intersected the indi¬ 
cator that the coarse gold was obtained. As the pitch of the beds is south¬ 
ward the same beds would be encountered in that direction at a greater 
depth, and if another quartz vein was intersected, the conditions would be 
similar. 
At 150 feet south of the shaft a cross-cut is driven in east about 30 feet, 
and it seems to be approaching centre country, to which it should be con¬ 
tinued. The intersection of the beds in which the indicator occurs with 
the large quartz reef should also be sought. 
As the pitch of the country is so considerable it should bring the deeper 
beds towards the surface in a northerly direction. 
It is observable that the reef is faulted and disturbed, but whether 
there are quartz veins on these faults is not known. If there is quartz at 
these faults the intersections with the indicator should be tried. 
Many of the rich alluvial gullies around Daylesford probably owe their 
coarse gold to the presence of an indicator in close proximity to where the 
gold was found.

THE FOREST CREEK GOLD REEFS AND THE FRANCIS 
ORMOND MINE, CHEWTON. 
By E. J. Dunn , F.G.S., Director, Geological Survey. 
The Forest Creek Gold Reefs. 
The Forest Creek Reefs mine is situated about one mile a little west of 
north from Chewton. The country rocks are Ordovician slates and sand¬ 
stones belonging to the Castlemaine zone. The underlying Bendigo zone is 
exposed along the Chewton railway line to the south of the mine and it 
pitches northward, and consequently the Bendigo 1 zone is below the present 
workings. All the work so far done has been in country east of centre 
country. Only in one west cross-cut has centre country been cut. This 
centre country is on the Wattle Gully line of reefs, and in the old workings 
of the Wattle Gully mine, 2 miles to the south, extremely rich spurs were 
formerly worked in eastern country and in the Bendigo zone. There is, 
therefore, reason to expect similar results when the mine reaches deeper 
levels and gets into the Bendigo zone.
