the surface along the strike of these folds, and it is in the slates that the 
main reef formations have been mined j they are most spurry when accom¬ 
panied by the main line of dyke. 
The Golden Gate reef channel (Little Nell and Bismarck) strikes 
N. io deg*. W. and dips 80 deg. W., cutting across slates which dip 70 
deg. E. ; it is formed along a fault fissure. The formation consists of a 
quartz reef with quartz spurs on the footwall, the whole being from 2 feet 
to 4 feet in width. The channel at present traverses favorable slates 
mainly of a green colour. The quartz is often of a vitreous and laminated 
character and carries patches of iron pyrites both fresh and oxidized. 
The north workings are known as the Bismarck and the south as the 
Little Nell. 
The Bismarck Workings. 
The Bismarck portion of the line is now being mined by a tribute 
party whose deepest workings are at 84 feet from the surface in thp 
Bismarck main shaft, where there is a drive 25 feet or so in length with 
stopes behind south and above. There are several shafts, mostly on the 
underlay. Taking an average it may be said that the stopings are 90 feet 
long by 60 to 84 feet deep in places at the present time. Besides this 
there is a small amount of stoping done around the North Bismarck shaft 
The stoped ground as yet does not give sufficient data to determine the 
pitch of the Bismarck shoot, but further development of the mine should 
soon settle that point. Although the Bismarck workings are north of the 
cross fault and dyke there are patches of felspar nearly 200 feet away 
from any dyke rock, showing the far-reaching influence of the dykes when 
in contact with a line of reef. 
The Little Nell Workings. 
Southwards and across the gully are the workings of the Little Nell, 
which are at present inaccessible but are shortly to be examined by the 
company. I made a careful surface examination of these workings in 
company with Mr. Clements, the manager, who informed me that the 
deepest shaft is sunk 90 feet and the stopings are reported to extend from 
a depth of 80 feet to the surface on a reef formation from 6 inches to 
4 feet wide and from nearly vertical to westerly in dip. By dropping the 
tape down some of the shafts along the stoped area I was able to find 
that, at least in the top of the stopes, the pitch of the shoot had been from 
15 deg. to 20 deg. N. Seeing that practically throughout the Wehla field the 
shoots have been to the north, I consider that the pitch here and also- at 
the Little Nell will -be to the north, and especial care will be necessary in 
following it through the cross fault dyke as the dyke may dip south and 
prove misleading, as it might make the shoot appear to trend south. 
After the dyke comes in on the cross fault it turns and runs 
along the Little Nell line, showing in nearly every mullock heap. The 
shafts are numerous and vary, I am told, from 40 feet up to 90 feet in 
depth. Good specimens have been found south of the Little Nell but not 
much work has been done. 
Magazine Reef. 
In conclusion another reef in the lease may be noted; it strikes 
N. 18 deg. W. and dips 70 deg. W. in eastern beds. The Magazine reef 
will be a convenient name for it. It is a smaller reef formation, and as 
can be seen by its relative strike and dip, will soon junction with the main 
reef to the north of the Bismarck workings. A return of 6 dwt. from a 
small parcel of quartz is reported.
