From the survey it is apparent that the work in this mine has hitherto 
been confined almost exclusively to spurs. These, while at times rich, 
have not proved to be payable throughout, owing to the irregular nature 
ot their formation and distribution, ai enough no evidence was obtainable, 
it is quite likely that certain belts of strata contain more auriferous veins 
than others, and were this proved, work could be confined to these belts. 
The centre country should certainly be prospected, as the occurrence 
of well-defined legs at the lower level proves the existence of formations 
similar to those so extensively worked at Bendigo.

MULROONEY’S LEASE, JUBILEE LAKE COMPANY, 
DAYLESFORD. 
By E. ]. Dunn , F.G.S., Director , Geological Survey. 
The country rock consists of Ordovician slate and sandstone of grey 
colour. Strike, about N. io° W., dip E. A shaft has been sunk 30 feet 
deep, at a distance of about 6 chains in a southerly direction from the 
mineral spring. About 1 chain west of the shaft a large outcrop of quartz 
is exposed, in which a little gold exists. Strike of this reef, N. io° W., 
the same as the country-rock, dip about 40° west. The reef cuts right 
across the bedding planes of the country. It has been worked by a 
shaft further south, and some crushings have been taken out. The reef 
is traceable for many chains southward from where previously worked, 
but it runs through private property. About 2J chains south-west from 
the spring the country dips west 70°. 
Alluvial workings extend over the shallow flat, in which the mineral 
spring occurs and up this, line of reef; in one spot the alluvial gold has 
been traced beyond the line of this reef. The southern shaft is 80 feet 
deep. 
This area has been applied for as a mining lease, but the mineral 
spring would be endangered by mining operations in such close proximity 
to it.

THE AJAX MINE, DAYLESFORD. 
By E. J. Dunn , E.G.S., Director, Geological Survey. 
This mine is situated about 1 mile to the north-west of the town. The 
country rock consists of grey sandstone and slate. Strike, about N. 20° W. 
A shaft, 11 feet by 4 feet, has been sunk at this mine to a total depth 
of 386 feet, and there are three levels: No. 1 at 220 feet, No. 2 at 
300 feet, and No. 3 at 380 feet. 
At No. 2 level the country rock dips east 55 0 . The lode which is 
similar in character to the Cornish Lode, dips west at 52 0 , cutting right 
across the bedding planes of the rocks. In strike the lode appears to 
correspond with the strike of the beds, or, in other words, the lode appears 
to have formed in a strike fault. The thickness of the lode ranges from 
1 to 3 feet. The pitch of the lode and of the beds is south 7 0 . This lode 
has been stoped for a length of 330 feet on this level, and overhead 
to the level above. A cross-cut has been driven east from this level for 
300 feet to the old Ajax Reef. This lode dips east at 70°, and cuts right
