Trom the second cut, 20 ft. to the north, a sample was taken from 
12 in. of quartz with arsenopjrite on the west side of the lode, and 
assayed— 
Sample hfo. 702— 
Gold . . . . 11 dwt. 18 gr. per ton. 
Silver . . . . 4 dwt. 14 gr. per ton. 
Tungstic acid . . I7il. 
The samples were also tested for tin and copper. These metals were 
found to be absent. Samples JSTos. 699 and 701 represent highly pay¬ 
able wolfram ore containing 13 and 30 per cent, of wolfram respectively. 
The value of the concentrates ranges from £80 to £100 per ton. 
In sample Ho. 702 the gold is associated with arsenopyrite, no free 
gold is present, and the value of the ore has not been enhanced by surface 
enrichment. The mine is situated 7^ miles from the Government Bat¬ 
tery at Chiltern, and the carting and crushing would be about 15s. per 
ton. Sufficient work has not yet been done to prove the extent of pay¬ 
able ore, but with further development there is every prospect of the 
mine developing into a payable proposition.

THE CHILTEKH GOLDEH BAK MIHE. 
By J. P. L. Kenny, Assistant Field Geologist. 
The 'Chiltern Golden Bar lease is situated about 2 miles east of 
Chiltern township, and includes three main lines of reef, now known as 
the Golden Bar, the Ho. 1, and the Ho. 2. The Golden Bar reef 
was formerly known as West’s reef, the Ho. 1 as Higgins’, -and the Ho. 
2 as the Alfred or Alabama reef. In addition to these, a diagonal 
reef, known as the Alfred leaders, connects the Ho. 1 and Ho. 2 reefs. 
The main reefs run in approximately parallel lines, with a strike of H. 
30° W., and usually dip within 10° of vertical. The reefs are 
intersected by slides which strike H. 40° W. and dip 45° west. 
Three of these slides have been met in a vertical depth of 730 ft., the 
position of the present bottom level. They are reversed faults, the 
hanging wall country having moved relatively in an upward direction, 
and the displacement is usually less than 50 ft. Only one cross-course 
occurs in the mine, about 400 ft. north of the shaft; the reef on the north 
side of the cross-course is heaved a few feet to the west. 
A diorite dyke running nearly east and west intersects the reefs 
250 ft. north of the shaft. The dyke has not had any influence upon 
the gold in the reefs. 
The country rock consists of normal slate and sandstone, strike 
H. 30° W. The beds have a general dip to the west, often at a low 
angle. At the Ho. 3 level in the present company’s shaft a remarkably 
flat bed of slate occurs. It dips to the west at such a low angle that 
it can be traced in the cross-cut for a distance of 70 ft. Minor synclinal 
and anticlinal folds occur to the west of the Ho. 1 reef, and probably 
a main syncline will be found further west. 
Generally, the formations may be described as nearly vertical fissure 
reefs on the east side of a main syncline intersected by west dipping 
slides. The earlier workings on the reefs include open cuts, tunnels, 
vertical and underlay shafts, the workings extending in some cases to
