South of the main workings the party have sunk an 8-ft. shaft on the 
same line, exposing two cross veins dipping south at an angle of 80 deg. ; 
both show very encouraging prospects. At a depth of 22 feet or so the 
slides will cut these cross veins and indicators, moving them also to the 
east. 
About 1 chain up the hill to the east there is another set of 
indicators on which a cross vein gave good prospects of coarse gold, which 
cut out in a few feet. In regard to these eastern lines of indicator, it 
may be pointed out that the main big slides would not cut them off 
until a depth of 50 feet has been reached, which is in their favour.

THE LANDSBOROUGH AURIFEROUS LEADS, EAST OF 
STAWELL. 
By E. J. Dunn , F.G.S., Director , Geological Survey. 
In this district there are three distinct systems of auriferous alluvial 
leads. 
1st. The oldest is probably of Pliocene age. It starts near the 
Malakoff Gap, 7 miles south of Landsborough, and runs in a northerly 
direction, keeping on the western side of the valley for about 6 miles. 
The lead has been broken into a series of outliers by gullies that run in 
an easterly direction from the north and south main range. The height 
of this lead above the valley is about 150 feet, and it has been worked 
for gold throughout. Heavy quartz boulders and pebbles but partly 
rounded form the feature of the washdirt. 
2nd. The White Lead is possibly of Post-Pliocene age. It runs nearly 
parallel to the old lead, but is further to the east. White quartz wash- 
dirt on a pipeclay bottom is characteristic of this lead. At any rate, 
part of the gold in this lead has been derived from the older lead, which 
is at a higher level. 
3rd. The Recent leads consist of brown gravel, and their feeders 
intersect the old lead. Sandstone and slate form a considerable propor¬ 
tion of . the washdirt in them. The principal Recent lead is again to the 
eastward of the White lead, and at a lower level. Gold from both of the 
older leads has been transported to the Recent leads. There are numerous 
gullies with washdirt of this age crossing the old lead, and these have 
contributed the gold to the main lead and to the patches of this age. 
It appears as though most of the gold of the three classes of washdirt 
has been derived from the ridge running in an east and west direction, 
the lowest point of which forms Malakoff Gap, and, of course, from 
country at a higher level than the present surface. The Gap is a low 
notch in the east and west range that crosses the strike of the Ordovician 
rocks. Through it the road passes, and the cutting exposes slate and sand¬ 
stone of favorable appearance, and with a strike of about N. 30 deg. W. 
There are two dykes exposed in this cutting. The east and west ridge 
forms the present watershed, and it appears to have been the watershed 
in Pliocene times, for the old lead trends away from it in a northerly
