The Horseshoe Bend Reef. 
About half-a-mile north of the bridge over Cobban River at Lvall is 
the Horseshoe Bend reef. The strike of the reef is N. 30 deg. W., dip 
67 deg. W. The quartz is 6 inches to 8 inches thick. The country rock 
on the east side of the reef is coarse, harsh, grey sandstone with numerous 
quartz spurs. On the west side of the reef the country rock is yellow slate 
and the soil is yellowish to red. The reef is on a fault line. I he country 
on the east siue is the footwall and is barren. On .the hanging wall or west 
side of tire fault the country has been thrown up and by this means beds 
of a productive nature have been brought to the surface and the quartz 
vein lying between barren country on the east and productive country on 
the west side is auriferous. The strike of the country rock is N. 40 deg. 
W. and the dip 62 deg. E., so that the fault does not coincide quite with 
the strike of the rocks, and in dip it crosses them. The pitch of the country 
is to the nortn at 7 deg. at the workings a little to the south of east from 
the Linda mine. 
This line of reefs has been worked at intervals for a distance of nearly 
2 miles. It was most actively worked about 40 years ago. Several shafts 
have been sunk to depths exceeding 100 feet, and a very considerable ton¬ 
nage of quartz must have been crushed. No great amount of work appears 
to have been done below water level, and there seems good reason for 
believing that there is room along this line for further prospecting. The 
water is not likely to prove very difficult to deal with. 
Parallel to the main line of reef, but half a chain away from it on the 
west side, is a small reef with about the same strike and dip which has been 
worked in places. The pitch is the same as in the main reef and the shoots 
of gold follow the pitch of the country in this case also. 
About 2 miles east from the Horseshoe Bend reef is Potter ? s reef, which 
was worked about the same Time as the other reefs in the neighbourhood. 
The Linda Reef. 
About 12 chains west of Horseshoe Bend reef is the Linda reef. It is 
about half-a-mile northerly from the bridge over the Coliban River, and it 
can be traced nearlv to the river in a southerly direction. The mine is now 
j j 
being worked and a steam winch is being used for hauling and bailing. 
The shaft is 175 feet deep; the strike of the reef N. 15 deg. W., dip 60 
deg. W. The pitch of the country is 15 deg. S., and the pitch of the shoot 
of gold corresponds to this. The shaft is 175 feet deep, and at 60 feet a 
level has been driven 100 feet northward and 70 feet southward. At 
120 feet a. level is driven 50 feet northward and 200 feet southward. At 
167 feet a level runs- 100 feet northward and 240 feet southward. There 
are three small quartz veins, each from 1 inch to 4 inches thick, one on the 
footwall, one on the hanging wall, and an intermediate one between the two. 
The distance between the footwall and hanging wall ranges from about 
8 feet to over 20 feet. 
Besides the quartz veins, which are rich in gold, the casings are taken 
for a width of from 6 inches to 18 inches. The footwall and intermediate 
veins have been stoped from the 167-ft. level to the surface but the hanging 
wall vein has only been stoped in one part to the 120-ft. level. Owing to 
the pitch of the country the gold has gone under foot and the south end of 
this level shows a remarkable mixture of quartz veins and black shalv 
mineral between sandstone walls on the hanging wall side. At the extreme 
south end of this level black carbonaceous slaty bands are disclosed which 
account) for the black material associated with the quartz veins.
