Working becoming irksome in the inclined drive, the mine was temporarily- 
abandoned, and a shaft started in quartz which outcropped at 190 feet north 
of the main shaft. A depth of 28 feet has been attained here, and from the 
bottom a drive has been put in 25 feet north on the west leg of a small saddle 
reef pitching 40° N. From this reef (cap and leg) 14 tons have been crushed 
for a yield of 8J dwt. per ton. The axial strike of the anticline containing 
this reef is about N. 3° W., the anticline being about 40 feet east of the main 
shaft. 
Along the strike northward from Patten’s shaft, auriferous quartz has 
been found at intervals for over a mile, and several gullies, below where they 
are crossed by the line of strike, have been worked for gold. Bedrock expo¬ 
sures not being continuous, it is not easy to trace the line in either direction. 
To date operations by the present holders have proved just about payable, 
notwithstanding that the quartz for crushing has to be carted to the Govern¬ 
ment battery at Amherst, 14 miles distant, and, as far as can be judged from 
the open workings, and the information supplied with regard to the closed 
portion of the mine, it seems advisable to continue prospecting the western 
reef, and also to sink in the anticline in search of other saddle reefs which 
experience shows are likely to recur with depth.

THE YANKEE DOODLE REEF, GOLDSBOROUGH. 
By A. M. Howitt, Field Geologist. 
The exact locality of the Yankee Doodle Reef is on the north side of 
Nuggety Gully, and 300 yards east of Whittaker’s allotment 19, parish of 
Painswick. It is about one mile south of the Queen’s Birthday mine, and is 
on the same line of reef. 
The shallower workings were examined in 1909, and a report on them was 
published 1 . 
Since the inspection in 1909, Skane and party have sunk a vertical whip 
shaft to a depth of 150 feet. This shaft is only 23 feet at N. 5° E. from the 
old 40-ft. north shaft. It has levels at 50 ft., 100 ft., and 150 ft. 
At the 50-ft. level the black slates referred to in the previous report were 
cut at the shaft and driven on 13 feet north and 37 feet south. In these black 
slates decomposed iron pyrites is abundant. From the end of the south drive 
a short cross-cut west is connected by a rise to the old 40-ft. shaft, and from 
which the best assays of black slates came. Here the strike is N. 20° W., and 
the dip 75° E. A section of this south end shows three narrow bedded quartz 
veins among fche slates. 
From the 50 ft. level a parcel of 2 tons of black slate and quartz veins has 
recently been taken out and sent to the Ballarat School of Mines for treatment. 
At the 100-ft. level a cross-cut west for 70 feet shows at 3 feet a 3-inch 
quartz vein and about 6 inches of a graphitic vein cutting the strata at a small 
angle ; at 21 feet, a 3-inch bedded quartz vein separating the softer black 
slates from a 10 ft. series of hard black slate ; from 31 feet to 70 feet, light- 
coloured slate beds, only slightly mineralized and showing no quartz veins. 
The east cross-cut was mullocked up and inaccessible, but from information 
supplied it appears that alternate beds of black and grey slate occur for a 
distance of 14 feet, followed by 16 feet of light-coloured beds with quartz veins 
throughout. The footwall of this spurry formation is sandstone, and its dip 
is about 75° W. The length of the cross-cut is 32 feet.
