CAMPBELL’S REEF, MOYSTON. 
By E. J. Dumi , F.G.S., Director , Geological Survey. 
The strike of Campbell’s Reef is N. 20 deg. W., and its dip is 
nearly vertical, but slightly to the E. The country rock consists of highly 
altered yellow sandstone and slate, which are grey below water level. 
The reef ranges from 3 inches to 6 feet in thickness and the quartz is 
laminated. It averaged 1 ft. 6 in. thick, and the shoot of gold pitched 
northward. 
For a length of over half-a-mile this reef was worked by means of 
shafts, the deepest of which is on the Kangaroo United lease and 550 feet 
deep. 
The reef runs along the top of a ridge to. the west of the town¬ 
ship. The hill is covered by a capping of Older Pliocene conglomerate, 
which was auriferous, and the western slope of the hill has been exten¬ 
sively worked for surfacing and shallow alluvial deposits. Both the 
Older Pliocence conglomerate and the reef contributed towards the gold 
found on the slope, the former well rounded gold, the latter sharp hackly 
gold newly broken from its matrix. The latter gold is reported to be 
worth ^4 2S. 6d. per oz. In the Kangaroo United mine a large fels- 
pathic dyke occurs. 
About 100 feet east of Campbell’s reef isi a small but very rich reef, 
called the East Spur. It is about 1 inch thick and is traceable for some 
hundreds of feet in length, and has been worked down to 300 feet for part 
of its course. A small piece of this stone shown to me was thickly studded 
with gold. A party of three men is now at work on the south end of this, 
where they are sinking a shaft to pick up the continuation of this rich 
vein. With this exception nothing is being done on this line of reef. 
The companies formerly working the Campbell’s reef were (beginning 
at the north end) the North Star, the Southern Cross, the Kangaroo United, 
the Three Crowns, and Kennedv’s. 
At the south end of Campbell’s reef, some work has been done on 
auriferous spurs, apparently with profitable results. 
Half-a-mile south from the deep shaft in the Kangaroo United mine is 
the Sir George Bowen mine. The shaft is about 300 feet deep. South¬ 
ward from this and westward from Campbell’s reef the country offers 
inducements for the prospector. 
At Moyston there is a belt of Ordovician rocks. Two miles 
east of Moyston is a belt of grano-diorite brecciated in appearance 
and similar in aspect to the grano-diorite that is favorable to the 
occurrence off gold, silver, copper, lead, and tin ores. At Carroll's 
Cutting, miles from Ararat, the highly altered schist strikes 
N. 30 deg. W. and dips 72 deg. W. At Cope’s Hill, if miles from 
Ararat on the Moyston road, the altered schist and sandstone are highly 
contorted and strike N. 30 deg. W. Judging from the manner in which the 
alluvial gullies, which head from these altered sandstones and schists, have 
been worked for gold, these beds should be gold-bearing, but there is little 
evidence of reefs having been found in them.
