At the 480-foot level the cross-cut to the west in centre-country is 100 
feet to the east of the shaft, and at the 560-foot level it is 105 feet to 
the west of the shaft, so the manager informed me. These two levels were 
under water at the time of my visit. 
A feature at this mine is the abundance of large bodies of quartz 
carrying gold that occur to the east of centre-country. Centre-country 
winzes have not been carried down through the mine, .and so the chances 
of saddle-reefs have not been determined. 
The mines at Spring. Gully are in a most favorable belt of auriferous 
country. The alluvial workings follow up all the main and minor water 
channels right into the hills. The Spring Gully mine and the adjacent 
mines are on a well-formed anticlinal axis, and there is everv reason to be¬ 
lieve that if the mining here were conducted as at Bendigo', in search of 
saddle-reefs and their “ legs,” and for spurrv country connected with the 
“ backs,” these mines would be very profitable to work, and would also be 
likely to have a very extended life. 
If suitable arrangements can be entered into with this company, I 
would strongly advise vertical boring from the bottom cross-cut to the west, 
so as to intersect saddle-reefs. Whether boring is done or not, these mines 
should have their shafts sunk deeper, with the object of exploring the 
country at greater depths. All the features in this neighbourhood point 
to this as being probably a very rich field for quartz-mining enterprise. 
Owing to the removal of auriferous quartz too close to the shaft, 
damage has been done, and the shaft rendered insecure. It is doubtful 
if it could be depended upon, as this mine can look forward to great depths 
below the present bottom level that will have to be explored. 
I would recommend that from the bottom cross-cut to the west a drill¬ 
hole, inclined to the west at about the angle disclosed in this mine that 
centre-country makes from the vertical, should be put down in centre- 
country. At the surface centre-country is about 70 feet to the west of the 
shaft. At 560 feet centre-country is 105 feet to the west of the shaft. 
Before any bore-hole is started, I should like to see the bottom levels. 
In the event of a bore-hole being successful, it would affect, not only the 
group of mines now at work at Spring Gully, but the whole anticlinal line 
would be benefited, and probably adjacent lines as well.

SOME GOLD-MINES AT BERRINGA. 
(NO. 26 ON LOCALITY MAP.) 
By E. J. Dunn , E.G.S., Director , Geological Survey. 
During the progress of his geological survey at Berringa, Mr. W. Barag- 
wanath, junior, found that saddle-reefs were being worked at three of the 
mines there, and that, although the true nature of these reefs was recog¬ 
nised by Mr. Robert F. Bryant, the manager of the Kangaroo mine, their 
significance was not generally recognised. 
In company with Mr. Baragwanath I have inspected the three mines,, 
and fully confirm his determination.
