THE GOLDEN EAGLE LODE, COOKIMBURRA, NEAR 
BARNAWARTHA. 
(no. 3 ON LOCALITY MAP.) 
By E. J. Dunn , F.G.S., Director , Geological Survey. 
Messrs, Boucher and Ashe have continued the sinking at this locality, 
which is about 3 miles south-east of Barnawartha, and they have 
developed an interesting occurrence. The shaft is now 31 feet deep, 
and at the bottom there is a peculiar granitic rock that, for a width 
of 12 feet, is impregnated with sulphides of copper, iron, and 
lead. In some places the sulphides segregate into small rich 
patches. The ores here bear a strong resemblance to those occurring 
throughout the metamorphic area, and this is the extreme north-western 
locality in which such ores have been discovered. An average sample of 
the ore was collected for assay. This has been assayed by Mr. Bayly, 
at the Mines Department Laboratory, and the following results obtained: — 
Gold, 2 dwts. 14 grs., per ton of sample; silver, 12 dwts. 2 grs., per ton 
of sample; lead, 5 per cent.; copper, trace; arsenic, large amount.

THE OCCURRENCE OF GOLD IN OLIVER'S PADDOCK, 
NEAR KILMO’RE. 
(NO. 28 ON LOCALITY MAP.) 
By E. ]. Dunn , F.G.S., Director , Geological Survey. 
About 5! miles, W. 30 deg. N., from Kilmore some work has been 
done by the Kilmore Prospecting Association in the above paddock. Gold 
was first obtained by washing loams below the road. Some shallow holes 
were sunk also, but no colours of gold were obtained more than a few 
inches below the surface. By means of loaming, gold in the surface 
material was traced across the road and into Oliver's paddock, when the 
source of the gold was discovered. It is a fault line, striking E. 25 deg. 
N., cutting through the Silurian mudstones nearly vertically. In this fault 
line there is a little quartz that ranges up to as much as 1 inch in thick¬ 
ness, and which carries a little gold. On the western side of the fault, or 
“ wall,” thin auriferous quartz veins extend nearly at right angles into 
the mudstones. They are also almost vertical, and carry a little gold. Other 
thin quartz veins parallel to the fault are not auriferous. By means of 
surface trenches the wall or fault has been traced for about 3 chains, 
and its direction leads towards an old shaft that appears to have been 
sunk on a similar thin auriferous quartz vein to a depth of 40 feet. In 
the gully, north-east from this shaft, which was apparently sunk 20 or 
30 years ago, are a few workings for alluvial gold. Evidently some was 
obtained, but not in profitable quantities. About two chains south of the 
old shaft is a remarkable conglomerate apparently of Silurian age. The 
pebbles are much sheared. This conglomerate occurs over a wide tract 
of country, and holes have in many cases been sunk in it in the search for 
alluvial gold. 
The mudstones have ai favorable appearance for gold, and had the 
fault been continuous downward, it would have been worth following; but 
at a depth of 12 feet, so the prospector informs me, a nearly horizontal 
fault occurs, which has cut off everything above. There is nothing to 
determine the extent of the displacement, so that there is not much
