is traversed by quartz spurs. Along the level, 65 feet southward from 
the western leg, and in the stopes overhead, a great development of 
quartz has taken place on what is apparently a saddle formation. Quartz 
is very abundant in this portion of the mine, and is being sent for crushing 
from wide faces. 
At the 150-ft. level in the eastern cross-cut the country rocks dip west. 
At 30 feet to the east is centre-country. The pitch is 20 deg. to north, 
and at the shaft there is a syncline. 
The eastern leg is 12 feet along the western cross-cut, and the western 
leg about 60 feet in from the shaft. The striking feature in this level 
is the abundance of quartz of a profitable character. A great deal has 
been won here, and also from the winze below the level. Work is now’ 
being actively carried on in this level. The operations at this mine show 
that saddle-reefs and legs exist, as well as irregular spurs, and the results 
obtained by crushing large quantities of quartz are very profitable. For 
the last twelve months an average of 7 dwts. of gold per ton is reported. 
With the large bodies of quartz (as much as 30 feet across in one case) 
this return pays handsomely.

There is a substantial plant on the mine, and the conditions appear to 
warrant work on a much more extensive scale than at present. The 
structure disclosed augurs well for the future prospects of the several 
mines that are being opened up to the south of the Mundy Gully mine on 
the same belt of country. If this tract of auriferous country be vigorously 
worked it will probably result in reviving the quartz mining industry of 
Heathcote. 
New Year’s Venture Mine. 
The New Year’s Venture mine lies about half-a-mile south of the Mundy 
Gully mine. The shaft is 130 feet deep, and a drive has been made 
along the reef, which is stated to be from 2 to 3 feet thick, at 100 feet 
to the south, and 50 feet to the north. Forty loads taken from the 
southern drive yielded 3! dwts. of gold per ton. Twenty loads from the 
northern level gave b oz. of gold per ton, and another crushing of 20 
tons from the end of the northern level yielded 7! dwts. of gold per ton. 
The shoot of gold appears to dip northward, and a shaft was sunk to the 
north of the former shaft, so as to cut the shoot ahead of where the last 
crushing of ore was got. A quartz reef was followed down from the 
surface to a depth of 40 feet. The reef was 3 feet thick, and it is being 
further opened up. 
The South New Year’s Venture. 
This mine adjoins the New Year’s Venture mine on the south side. 
The beds here consist of soft sandstones and slates—yellow, grey and pink 
in colour. The strike of the country is N. 10 deg. W., and the 
dip easterly; the shaft has been sunk 100 feet. A reef is being worked; 
at 84 feet' from the surface it is 6 feet to the east of the shaft. The
