Most of tlie nodular schists are fine grained, but just two feet to the 
eastward of the indicator there is a bed of much coarser nodular schist, 
which forms a good guide as to the position of the indicator.

It is clear in the 
present case that the 
indicator has exercised 
a direct influence in 
causing the deposition 
of the gold, for it is 
\coarse spotted schists only within a few inches 
" E of the intersection of 
fiStnkeNPsw indicator by the 
quartz reef that gold is 
found. The gold is not 
of secondary character 
in the quartz vein, but 
was deposited at the 
same time as the quartz. 
It is of high quality, 
worth £4 3s. per oz. 
and ranges from very 
fine particles to half¬ 
ounce pieces. In the 
richer portions the 
quartz is held together 
by the gold. Felspar 
occurs fairly abundantly 
in some portions of the 
quartz, no doubt result¬ 
ing from the proximity 
of the granite, and par¬ 
ticles of gold are to be 
in some of the

In prospecting, the 
indicator must be fol¬ 
lowed closely ; and, 
wherever a quartz vein 
is found to intersect it, 
there is a chance of 
finding gold. As in 
many other cases, the 
indicator dips to the 
east, where it has proved 
to be so productive. In 
this district there is 
ample scope for pros¬ 
pectors who are quali¬ 
fied to follow up these 
indicators, but as tlie 
gold only occurs alone certain lines and at certain intersections, considerable 
experience is needed if success is to be obtained.
