From what could be seen of the workings, the formation appeared to 
he about two feet in width, with fair prospect of gold on both walls and 
throughout the central portion' of the formation. The reef dips east at 
an angle of 45 degrees, and its general strike is N. 18 deg. W. 
As large areas adjoining are held under prospecting claims, it is not 
advisable for prospectors to visit the locality at present, but the field is 
one on which numerous other outcrops most likely occur, and the rich 
patches of gold found in Fulton’s Creek strongly support this view.

THE CRINOLINE EXTENDED MINE, DONNELLY’S CREEK. 
By W. Baragwanath. 
The Crinoline mine is situated on the eastern side of the Morning 
Star Creek (one of the main heads of Donnelly’s Creek), near its junction 
with Growler’s Gully. 
The lode was discovered by surface loaming at a point about 150 feet 
above the level of the junction of Growler’s and Morning Star Creeks. 
The lode consists of crushed and broken strata, through which veins and 
strings of auriferous quartz occur in places. There is one well-defined 
wall, and the lode varies in width. Slabs of quartz occur along the wall, 
which has an average dip of 60 deg. to the east. Trial crushings from 
tne surface outcrop proving highly payable, a shaft was sunk to a depth 
of 55 feet, and from the bottom a stope was taken out to the south for 
a distance of 25 feet on a body of quartz up to 3 feet in width, and con¬ 
tinuing under foot. 
About 80 feet to the south-east of the main shaft, auriferous quartz was 
proved on the surface. Further south than this the whole of the strata 
on the hill-side has been disturbed by a terminal thrust. What appears 
to be the continuation of the reef can be seen in this faulted strata, but 
here it is almost horizontal. 
In order to test the reef at a depth, an adit was driven from a point' 
about 10 feet above the level of Morning Star Creek. This adit has a 
bearing of N. 25 deg. E., and it cut the line of reef at a point 236 feet 
from the entrance. The reef, where cut, carried a make of quartz about 
8 inches wide, with 3 feet of crushed country rock, and veins of quartz 
on the western side. Drives have been put in 79 feet north and 30 feet 
south. North of the crosscut two rises were put up. The first at 15 feet 
north was up 41 feet at the time of this survey. This rise exposed a good 
hanging wall, dipping to the east at 60 deg., with a body of crushed 
strata and spurs 2 feet in width, and occasional splices of more highlv 
inclined quartz. 
The line of lode occurs along a fault (which is one of many in the 
neighbourhood) near the contact of a wide belt of hard coarse sandstones, 
through which numerous segregated veins of quartz occur, and a still 
wider belt of phyllites and slates. Although no direct evidence as to the 
age of the beds has yet been obtained, it appears highly probable that they 
are Ordovician. The same belt of auriferous country extends from 
Edwards Hill, about i| miles to the south, past the White Star and 
Blackwall mines, and has been proved auriferous at numerous places along 
its course. Two series of faults! occur in the mines to the south, one 
series having an easterly and the other a westerly hade. Very rich yields 
have been reported from the reefs associated with these faults, along* some 
of which adits have been driven for over a thousand feet.
