THE BAND AND LOCH, NEW KOHINOOR, AND SEBASTOPOL 
PLATEAU No. i MINES, BALLARAT. 
By E. /. Dunn, F.G.S., Director, Geological Survey. 
The Band and Loch Mine. 
The operations at the Band and Loch mine are now confined to the 
No. 9 shaft of the former Band and Albion Company, which amalgamated 
with the Sir Henry Loch and formed a company under the style of the 
Band and Loch. 
The lowest level is at 2,300 feet, and from this level operations have 
been directed to the development of the. Consols line of lode. This line 
of lode was worked with profitable results to a depth of over 1,800 feet 
from the Sir Henry Loch shaft. An examination of the mine plans shows 
that at least two distinct shoots of payable stone occurred in this lode. 
One, the cap of which was found in the New Kohinoor Company’s mine> 
pitched southerly, and passed through the Sir Henry Loch ground, the 
Band and Albion, past the Nos. 7 and 10 shafts and through the Star of 
the East Company’s No. 1 shaft workings, in all having a length of about 
a mile, and reaching at the point last worked a depth of 2,000 feet below 
the surface. Another shoot of payable stone was worked in the Sir Henry 
Loch Company’s ground to a depth of 1,800 feet, the make, although the 
reef had a well defined westerly underlie, appearing almost vertical, i.e., 
without any pitch to the north or south. 
At 1,900 feet in the No. 9 shaft a crosscut was put out easterly for 
875 feet, and at drive northerly on what appears to be the lode track. 
At 630 feet north of the crosscut a blind shaft, equipped with an air winch, 
was sunk to a depth of 180 feet. Five hundred and eighty feet north of 
the blind shaft on the 1,900-ft. level, a payable shoot of stone—the down¬ 
ward continuation of that formerly worked by the Sir Henry Loch Com¬ 
pany—was met with. The lode averaged about 4 feet in width, and was 
stoped upwards to the 1,830-ft. level of the Sir Henry Loch. From the 
bottom of the blind shaft a drive (the 2,080-ft. level) was put in north, 
and the payable shoot again intersected. Here the lode is of large dimen¬ 
sions ranging up to 60 feet in width, and there are large spurs further 
w T est. The eastern wall of the lode has a well defined westerly underlie, 
and agrees with that proved throughout the Sir Henry Loch workings. 
Intermediate levels for sloping •were opened between the 1,900 and 2,080 
feet levels, in each of which large bodies of stone were exposed and 
profitable crushings were obtained therefrom. An interesting feature, and 
one which has been carefully noted by the manager, is the occurrence of 
pyrite seams and black slate beds analagous to the Ballarat East Indicators. 
Professor Gregory* compares them to fahlbands, but states that they are too 
short and irregular to be entitled to rank as such. Although my 
visit, on account of the extensive nature of the workings, was necessarily 
incomplete, sufficient evidence was obtained to show that for several 
hundreds of feet these bands have been partially exploited, and a number 
of veins, some of large dimensions, and yielding up to 5 ozs. to the ton, 
found to occur. 
Similar bands, probably in the same zone of country, are to be seen in 
the Kohinoor mine in the north where there is evidence of repetition of 
the beds by folding. Very rich spurs were worked during the ’8o’s in 
shallow levels by the Washington Company and a number of freehold 
companies, and similar pyrite seams and black slate beds were noticed 
and recorded on the mine plans.
