The auriferous makes occur in Silurian sedimentary rocks consisting of 
the following series :— 
(i.) Grey indurated sandstones. 
(2.) Soft brown micaceous sandstones with numerous ferruginous 
joint planes. 
(3.) Soft fine blue-grey sandstones with occasional joints. 
(4.) Crushed grey, red, and brown fine siliceous sandstones with 
numerous ferruginous joints; and blue-grey shales intersected 
by thread-like veins of quartz. This series of crushed beds 
contains antimony oxide. (Localities Nos. 1 and 2.) 
The dip observed in the underground workings is 50 deg. to the south¬ 
west, and. the strike observed at various points along the outcrops about 
N. 40 deg. W.

SKETCH SECTION 
The main work has been done on a cross-vein formation composed of 
quartz, ironstone, and pug, which the prospectors discovered about four 
months ago, and have since followed on its north-eastern underlay by 
means of an open cut. A vertical shaft was afterwards sunk to a depth of 
13 feet to connect with the open cut, and at this level the formation bulged 
to over 1 foot in width, including 4 inches of quartz; but where now seen 
in the north-western face the vein is small. (See fig. 37.) 
To intersect the vein at a lower level, a vertical shaft was sunk at a. 
point 24 feet north-east of the 13-ft shaft, and at the depth of 29 feet a 
cross-cut was driven 15 feet in a south-westerly direction, where it cut a
