in these beds dip W. and then all the beds dip W. to the present end of 
the tunnel which is at 1,194 feet. The beds E. of the barren sandstones 
are lower in the series, and they consist of soft light grey slates and sand¬ 
stones. This belt of country continues to the O’Connor’s reef, and is 
productive of gold. At 964 feet from the mouth of the tunnel what is 
considered to be the Queen’s Birthday line of reef has been intersected. 
The strike of the reef is N. 15 deg. E., dip 50 deg. E. There are three 
veins of quartz showing in the S. level, which is driven 34 feet from the 
tunnel. The most easterly quartz vein is about 2 inches thick. At 1 ft. 
6 in, further W. is another quartz vein from 1 to 2 inches thick. At 3 feet 
still further W. is the third quartz vein, also about 2 inches thick. The 
quartz carries gold. The country is light-grey slates, &c., pitching N. at 
15 deg., and the gold shoots follow 7 the country. As the pitch is north¬ 
ward, the level should be continued southward. The quartz here is 
oxidised, and to ascertain its character wdiere unaltered a winze should be 
sunk. At a very moderate depth water will probably be struck. The dip 
of the country v 7 here the Queen’s Birthday reef cuts through it in the 
tunnel is 70 deg. W. 
The track, of the reef is easily followed, and by driving along it the 
various shoots will be discovered. The rock is easv to v 7 ork. The backs 
are shallow as the surface is only about 70 feet above the tunnel floor. 
At 1,102 feet from the tunnel mouth, what is believed to be the Stack¬ 
yard reef v r as cut. The strike of reef is N. 5 deg. W., dip about 87 
deg. E. The strike of the country rock is N. 22 deg. E., dip 50 deg. W. 
The country consists of light-grey soft slates and sandstones. The pitch 
of the country is apparently about 45 deg. N. The Stackyard reef (so- 
called because it runs through the stackyard of the farm) is marked where 
the tunnel cuts it by a shoot of auriferous quartz, vdiich is about 6 feet 
long on the floor of the tunnel, and which pitches N. with the country. 
The quartz, on being broken. shows iron and copper pyrites and particles 
of gold disseminated in the heart of the quartz. The quartz vein ranges 
from 2 or 3 inches to 7 or 8 inches thick. 
It is of importance that these lines of reef should have been picked up, 
and if they open out like some of the reefs formerly worked in this neigh¬ 
bourhood, profitable mining may be re-established.

THE MIA MIA MINE, REDESDALE. 
By H. S. Whitelaw. 
The Mia Mia mine is situated on the western bank of the Campaspe 
River, about 3 miles north of the Redesdale township. Reef gold was first 
discovered in this locality about four years ago by a party of prospectors, 
who found a rich specimen in the river valley. By loaming the hillside 
the gold was traced to its source—quartz deposits about 40 feet above the 
river bed. A claim was pegged out and a crushing broken which averaged 
J oz. of gold per ton, a return not quite payable under the then existing 
conditions. Without further prospecting, the claim w r as abandoned. Two 
years later Mr. J. Day visited the locality, sampled the surface quartz, 
and formed the Mia Mia Gold Mining Company, vdiich erected an 8-head 
battery capable of crushing 20 tons of quartz per shift, and has since pro¬ 
fitably worked the quartz bodies above referred to.
