THE BENDIGO GOLDFIELD PROPRIETARY MINE. 
By E. J. Dunn, F.G.S., Director, Geological Survey. 
This mine is situate about 3J mile's "a little east of south from 
Bendigo. The shaft (the Diamond Hill shaft) is on the top of a hill, 
and is 606 feet deep. 
At a depth of 488 feet, in west crosscut, at 70 feet from the shaft, 
spurs were cut in the slate beds, and also what appears to be an east 
leg, with a thin vein of quartz. At 95 feet west of the shaft centre 
country was intersected. At 105 feet in, a dyke 4 inches thick was cut, 
and at 120 feet in, the west leg was cut. The pitch of the beds here is 
10 deg. to the north. The level passes through a fault, which cuts off 
the west leg south of the crosscut. The leg is heaved 5 feet to the east 
below the fault. 
At the 586 foot level, the slate and sandstone dip 60 deg. E. at the 
shaft. Centre country and a dyke 3 inches thick were cut at 70 feet 
west of the shaft. 
In this shaft the most necessary work is to sink; cross-cutting and 
level driving are quite useless until greater depth has been reached, and 
therefore nothing other than sinking should be done for at least another 
200 or 300 feet.

THE GARDEN GULLY CONSOLS MINE, BENDIGO. 
By E. J. Dunn, F.G.S., Director, Geological Survey. 
This mine is situated about a quarter of a mile north from the embank¬ 
ment of the Spring Gully reservoir. It is on the Garden Gully line of 
reefs and- the shaft is favorably placed for exploring them. Mr. "White- 
law has carefully followed out the lines.of pitch along the anticline, with 
the result that the favorable (Bendigo) zone, which is most productive of 
gold on this field, appears to be at no great depth below the present 
bottom of the shaft, which is now 290 feet below the surface. By 
sinking another 200 feet the Bendigo- zone would probably be entered, and 
it is in this zone, and especially in the upper portion, that saddle reefs 
bearing payable gold are to- be expected. I certainly recommend that 
the shaft be sunk, say, another 200 feet, and then cross-cuts could be 
driven westward to intersect centre country, and to search for saddle 
reefs. An important feature in this case is that the zone of productive 
country appears to- be within a moderate depth from the surface, and 
therefore the great expense of a deep shaft to- explore the country is not 
necessary. Should auriferous saddle reefs be cut in the shaft and pro¬ 
posed cross-cuts, it would probably result in the opening up of the line 
for miles in length. In the present position of mining at Bendigo this 
is one of the sites most deserving of attention.

CAMERON AND McRAE’S BEEF, CASTLEMAINE. 
By E. J. Dunn, F.G.S., Director, Geological Survey. 
The site of these workings, which are of a prospecting character, is 
about 3 miles east-north-east from the Castlemaine Post Office, and on 
the north slope of a hill. The principal shaft is 100 feet deep on the 
dip which is 35 deg. W. A syncline passes through the site. The
