Tanner’s Workings. 
Tanner’s old workings are about 20 chains a little east of south from 
the Golden Bar shaft. Payable quartz is reported to have been obtained 
here. 
All Nations Workings. 
About half-a-mile to the south of the above shaft, and in the Golden 
Bar South lease, are the All Nations workings, where three parallel reefs, 
dipping to the west, have been extensively worked. These are “ legs,” 
and indicate that centre-country is further to the east, and the shaft should 
be sunk near centre-country to work this ground systematically. 
Charlie Bruhn’s Reef. 
About 10 chains still further to the west is Charlie Bruhn’s Reef, 
dipping to the east, from which some rich small patches of quartz were 
extracted. This reef is between the bedding planes of the country-rocks. 
The rocks along the tract occupied by the above mines consist of Ordo¬ 
vician slates and sandstones, evidently belonging to a very productive 
zone, as the alluvial workings in the neighbourhood were rich in gold. 
Both to the east and west of the Golden Bar mine auriferous reefs were 
worked, and, from the nature of the case, cross-cutting will be the best 
way to develop the mine. The other mines in this group all appear to be 
on the same belt of country as the Golden Bar mine. 
The Robbie 'Burns Mine. 
This mine is situate ij miles north-east from Chiltern. The depth of 
the shaft is 333 feet. The beds dip to the west at 75 deg., while the 
reef dips to the east at 80 deg. From the bottom level to the surface 
this reef is intact. The pitch of the country-rocks is to the south, near 
the northern end of the northern level. The total length of this level is 
210 feet. The lode and spurs also are exposed in the northern face. 
The southern level is 108 feet in length to the western cross-cut, which 
is 130 feet long, in massive sandstone beds, dipping at 40 deg. to the 
west. In the face quartz spurs show that this cross-cut should be ex¬ 
tended a little further to the west, and it should certainly be extended 
eastwards. The end of the southern level is 242 feet from shaft. Near 
the southern extremity of this level quartz is being stoped. Besides the 
reef, 3 to 4 feet thick, which crosses the beds, and dips to the east, there 
is a small but rich “ leg ” of quartz that dips to the west. These two 
bodies of productive quartz intersect each other in the level. This leg is 
about 2 inches thick, and shows gold freely. Probably similar conditions 
to those present in the Golden Bar mine will be found to prevail in this 
mine. Cross-cuts to the east are much required, and this is the best direc¬ 
tion in which to open up the mine. 
In the Chiltern district there are great numbers of reefs that yielded 
good returns many years ago, and which are now abandoned. Probably 
work has ceased in many of them through those in charge of the mines 
failing to grasp the peculiar conditions under which the auriferous quartz 
occurs. The beds of the Ordovician series around Chiltern present all 
the features of highly auriferous country. The alluvial workings yielded 
gold in abundance, and, so far as worked, the reefs gave excellent results. 
There appears to be a wide scope for mining enterprise in this neighbour¬ 
hood.
