At the 3,824-ft. level the winze is 226 feet to the east of the shaft. 
The country-rocks at the shaft dip to the west. Centre-country and a dyke 
occur in the eastern cross-cut at 80 feet from the shaft. There are four 
“ backs ” with well laminated quartz “ legs,” 3 or 4 inches in thickness, 
at each. 
In the winze at 4,090 feet from the surface, gold was met with in spurs, 
and the manager states that auriferous spurs were met with to the bottom of 
the winze. Some of the spurs were of large size, and the shaft will be 
sunk to test them, as they are considered to be of payable character. 
The great depth at which this auriferous quartz is found in this mine is 
confirmation of the evidence obtained in the New Chum Railway mine. The 
actual opening up of gold-bearing quartz at these depths adds enormously to 
the prospective life of Bendigo as a gold-field. It serves as a stimulus to 
the whole field, and will inspire confidence as to the stability of the gold¬ 
mining industry, and as to the vast reserve of gold which lies stored up in 
the reefs and spurs of quartz that seam these corrugated beds. The work 
being done here serves as an object-lesson and a guide not only to other parts 
of the State and the Commonwealth but to the whole world where similar 
conditions prevail. 
It is now fairly well established th.at with such characteristics as are pre¬ 
sented by the Bendigo field, mining of a remunerative character depends 
principally on the extent of the operations. Once the base of the industry 
has become sufficientlv broad, that is to say, when a sufficient number of 
shafts have been sunk, and enough opening out work done to have a great 
number of faces in quartz, the industry will become a more regular one,, and 
the gold supply more steady. Bendigo has reached this stage, and every 
shaft sunk and cross-cut driven in a reasonable manner will tend to still 
further buttress the gold-mining industry and to render the average return 
more constant. 
I am greatly indebted to 1 Mr. Mining Inspector Abraham and to the 
manager of the mine for much courtesv and assistance.

THE GREAT SOUTHERN MINE, BENDIGO. 
(no. 8 ON LOCALITY MAP.) 
By E. J. Dunn , F.G.S., Director , Geological Survey. 
The Great Southern mine is situated on the Garden Gully anticlinal line. 
The depth of the shaft is 1,725 feet, and a cross-cut has been driven for 90 
feet to the east. The country-rocks are slates and sandstones dipping west 
and pitching south. At 80 feet from the shaft in the cross-cut is centre- 
country, and also a wedge-shaped mass of quartz that tapers out at the roof 
of the cross-cut, but which is some feet wide on the floor of the cross-cut. 
This has all the appearance of a saddle-reef, and it carries gold. This 
quartz is to be sunk upon at once, and its nature and value are to be tested. 
The countrv-rocks are of very favorable appearance, and are v r ell charged 
with pyrites. 
The lease on which the mine is situated w r as first taken up by an English 
company. It has a considerable length along the course of the Garden 
Gully line of reef. The company spent manv thousands of pounds in erect¬ 
ing ,a substantial plant and machinerv, and it sank the shaft to 1,200 feet. 
Some cross-cuts were also driven, and in one a saddle-reef was cut. This, 
however, so> far as the small amount of prospecting bestowed on it v r ent to 
prove, w-as barren. Then the patience of the shareholders became exhausted.
