THE SOUTH WATTLE GULLY MINE, CHEWTON. 
\ 
By W. Baragivanath, Senior Field Geologist. 
The South Wattle Gully mine is situated 1 mile south of the Chewton 
railway station, on the eastern side of Wattle Gully. Wattle Gully was 
famous in the fifties and sixties as an alluvial and quartz-reefing locality. 
The quartz workings were confined to spurs in broken country, occupying 
approximately a synclinal fold. On either side of the syncline well-defined 
anticlines occur, and on the eastern anticlinal fold the present South Wattle 
Gully mine is located. This anticlinal axial line can be traced from Fryers- 
town to near the granite contact, a distance of over 10 miles. At varying 
intervals along this line spurs and bedded reefs have been disclosed, and many 
payable returns obtained. Specimen Hill, a landmark near the Chewton- 
Fryerstown road, yielded rich spurs near the centre country at the surface, 
and a large open cut still marks the attempts of various companies to treat 
a large width of formation. The records of these companies show the stone 
to have been of very low grade, and, taken in bulk, unprofitable,- though a 
few individual spurs were rich. 
The present main shaft is located on the eastern side of the anticlinal 
fold, which at this point is remarkable on account of its width, being fully 
200 feet from side to side. The shaft is 30 chains north of Specimen Hill, 
and the anticline between the open cut and the present shaft shows a.northerly 
pitch throughout, varying from 15° to 25°. Work in the main shaft was 
confined to a bedded formation known as the German saddle, which has been 
stoped from the outcrop 400 feet south of the shaft to the 228-ft. level in the 
shaft workings. This bedded reef follows round the anticline, and pitches 
north from 15° to 35° on the cap. The east and west legs where stoped dip 
50° to 60°. From a survey made of the accessible workings in 1902, the reef 
was found to be from a few inches up to 3 feet in width, and two payable 
shoots were disclosed and worked to the surface. At the 228-ft. level the reef 
around the saddle is small, consisting of from 2 to 12 inches of nicely laminated 
mineralized stone, but it has not proved payable. The east leg varies from 
12 to 30 inches in width. 
At the 297-ft. level a cross-cut east from the shaft cuts the east leg, on 
which a drive north has been put in for 200 feet, the leg or back continuing 
small for the whole distance, although of promising appearance. The 
extension of this drive north for 100 feet will meet the saddle on its northerly
