The Stony Creek diggings are situate on a wide flat about 1,000 feet 
above Hall’s Gap, and there appears to be a little gold dispersed through 
the washdirt everywhere. The gold obtained here is pale in colour, and 
worth about £3 12s. per oz. 
Should the porphyry on petrological examination prove to be the same 
as the Snowy River porphyry, and interlaminated, then the Grampian beds 
would apparently belong to the lower Devonian series, and be below any 
beds likely to bear coal. 
Obsidian buttons are occasionally found in the washdirt.

PROPOSED BORING SITES AT BOGGY CREEK, MOUNT 
WILLIAM GOLD-FIELD, GRAMPIANS. 
By A. M. Howitt. 
The rocks in the vicinity of the Mt. William gold-field consist of 
granodiorite overlain by the Grampian sandstones; both in parts are 
covered by a varying thickness of Tertiary sediments. 
The object of my visit was mainly to see the country in which some 
further boring was desired. Mr. Langdon kindly accompanied me, and we 
proceeded along the present line of bores, thence west to Langdon’s claim 
on the Little Creek, where, I am informed, they can make about 15s. a 
man per week. Leaving this claim, we passed along Sawmill Creek for 
some distance, then branching off to the west, reached Pischoley’s Gully, 
where a patch of about 13 ozs. of gold was obtained in a run amongst 
large granodiorite boulders. We then went in a south-westerly direction 
to Boggy Creek, near the Wannon-road, at a point where the hill sides 
approach one another to within about 11 chains; the one side is granodiorite 
and the other a made hill, with the Grampian standstones showing above. 
P'he two localities where boring is favoured on the Boggy Creek fall are— 
(1.) Near the present line of bores and above Langdon’s claim, (n.) On 
Boggy Creek, one of the heads of the Wannon River. 
Mr. Langdon considers that the first of these sites should be tested, as 
proposed bore No. 90 (3 chains north-west of No. 89) was not put down, 
and there may still be room for a deep run of wash to pass through 
between No. 89 bore and the outcrop of granodiorite on the north-west, 
about 10 chains away; and in support of this opinion he states that the 
gold in his claim appears to have its source from that direction. I con¬ 
sider that there is nearly sure to be shallow ground at proposed bore No. 
90, as No. 89 bottomed at 27 feet; but unless this proposed bore No. 90 
is put down there will be a doubt about the depth, since the distance from 
proposed bore No. 90 to the main outcrop of the granodiorite is about 10 
chains. The surface indications point to the ground still being shallow, 
and a shaft would probably prove this without much expense. 
The second site is on Boggy Creek at a point where the hills approach 
one another, and, below the junction of several small gullies with this creek, 
there is a site favorable for boring, as far as position is concerned, but 
the other points to be considered are doubtful. 
In favour of this scheme it is urged that Boggy Creek is the only outlet 
for all the small gullies falling south-west from Mafeking West towards 
the Wannon River, and that these smaller gullies have prospects of fine
