the saddle-reef and from the leg is sent to the crushing plant, and averages 
4 dwts. of gold per ton; this yields a profit. This saddle-reef is also 
worked on the northern side of a cross-course that intersects and displaces 
the country and the reef for about 40 feet to the west, going to the north. 
In the quartz, sulphides of iron, arsenic, lead, and zinc are common. 
In the stopes, 40 feet below the No. 3 level and 50 feet north of the 
northern face of the level, the western leg is being stoped for a considerable 
length, and for a width of from 6 feet to 10 feet. The pitch is rapidly to 
the north. About 120 tons per day are being dealt with. 
That saddle-reefs exist at Berringa is demonstrated, and their import¬ 
ance can scarcely be over-estimated. The survey was partly undertaken 
with the object of tracing out the course of the anticline through this group 
of mines. This has been done as far as possible. In addition, actual 
saddle-reefs are shown to exist, and, still further, every one of these reefs 
so' far touched carries sufficient gold to make it very profitable to work. 
Quite a different phase is put on the field, for its permanency is assured, 
as also the expansion of mining. 
Saddle-reefs are being worked in the three mines, but the anticline 
goes through all the rest of the leases, and, as these saddle-reefs are highly 
auriferous, and occur in rapid succession, work should be at once undertaken 
to further explore centre-country by rises and winzes from the surface to 
the bottom levels, also to sink in search of them below the present depths, 
because it is known that they extend downwards for thousands of feet at 
Bendigo, and no doubt at Berringa also. The companies not working on 
centre-country should without delay cross-cut for it and explore it tho¬ 
roughly, for along it is where the most permanent and the most profitable 
mining will be done. 
These works may be undertaken with the fullest confidence, as the 
field is a permanent one, and with great resources awaiting development.

SOME GOLD-MINES AT CHILTERN. 
(NO. 27 ON LOCALITY MAP.) 
By E. J. Dunn, F.G.S., Director, Geological Survey. 
The Golden Bar Mine. 
This mine is situate about 2 miles east of Chiltern. The reef on 
which work is now being done is known as West’s, and it was discovered 
and first worked in 1859. The present shaft is 345 feet deep, and this 
is below all the old workings—a poor record for the operations of 45 
years, though, of course, the mine has not been worked for the whole 
period. Hauling and pumping machinery are being erected, so that sink- 
ing operations can be pushed on. 
There are two levels open—one (No. 1) at 242 feet, and the other 
(No. 2) at 345 feet. On No. 1 level, and 29 feet in the cross-cut to the
