REPORT ON THE HOMEWARD BOUND, PERSEVERANCE, 
BON ACCORD, VON MOLTKE, THE DYKE AND 
MOUNT STANLEY VIEW REEFS, HILLSBOROUGH, WITH 
PLAN AND SECTION (PLATE XXXIII.). 
By E. J . Dunn , F.G.S., Director , Geological Survey of Victoria. 
This locality is about 6 miles in an easterly direction from Stanley, 
in the North-Eastern District, and on the top of the ridge overlooking 
the valley in which Sutton stands. Sutton lies to the east of Hills¬ 
borough, at the foot of the range. About Sutton the country rock is 
granite, while at Hillsborough the rocks consist of quartzite and micaceous 
schist, apparently Ordovician beds altered by contact with underlying 
granite. The Homeward Bound Reef is on the edge of the range, and 
formerly the quartz was conveyed from the mine to the battery at the 
eastern foot of the range by a wire-rope tramway. The strike of the 
reef is about N. 15 deg. E., and the dip is 75 deg. to W. Just south 
of the main shaft the reef bifurcates, and the eastern branch, with a strike 
about N. and S. and dip to W. at 80 deg., is known as the Track Reef. 
Near the shaft the country rocks strike N. 20 deg. W., and dip to W. at 
about 70 deg. The main shaft is about 410 feet deep on the underlie, 
but it has* fallen together. This shaft should be reopened and deepened, 
so as to secure ventilation for the tunnel. 
At the surface the shoot of gold was about 200 feet long. It is 
reported that other shoots were worked lower down. The quartz reef is 
said to have been from 8 to 20 feet in thickness. I remember that when 
it was being worked in the “ sixties” the reef was a wide one. Twenty 
five feet north of the main shaft a fault cuts off the reef. This fault 
crosses through the shaft at 200 feet, and the reef is reported to have 
been worked south of this fault, but nowhere to the north of it. Pro¬ 
ceeding northwards, the throw of the fault is to the east. About the 
main shaft and to the south of it there has been much subsidence, which 
has extended along the Homeward Bound and the Track Reefs, indicating 
that very large bodies of material have been removed underground. 
For some years past mining has been practically at a standstill in this 
locality, but a tunnel, commenced some years ago, is being driven so as to 
intersect any reefs that may live in diepth below the workings that were 
formerly so productive. According to the survey recently made by Mr. 
A. W. Craven, this tunnel should intersect any reefs at about 200 feet 
below the old workings. A copy of Mr. Craven’s plan has been made 
by his permission, and accompanies this report. 
From this plan it will be seen that the level, extended in a north¬ 
westerly direction from the tunnel, is far to the west of where the down¬ 
ward continuation of the Homeward Bound Reef might be looked for, 
and also that the present north-westerly face of this level is about 100 feet 
due east of where the downward extension of the Bon Acsord Reef should 
occur. The tunnel has been driven in westward about 700 feet south 
of where the principal old workings were carried on, instead of directly 
underneath them. The north-westerly level followed a wall, but in a 
direction that does not correspond with the strike of the Homeward Bound 
Reef. For the last 200 feet a reef, gradually increasing in thickness 
as it was driven on northwards, has been followed. This reef is now 
2 feet thick in the face, and as the shoot of gold formerly worked was 
neith of the present face of the reef, I would suggest that it should be 
followed for another 100 feet to see if it improves in value. From the 
present extreme face of this north-westerly level a cross-cut should be 
extended westward, say, for no feet, so as to intersect the course of the 
Bon Accord line of reef.
