rHE GOLDEN BAR AND GOLDEN BAR EXTENDED MINES. 
CHILTERN. 
By E. ]. Dunn, F.G.S., late Director, Geological Survey. 
The Golden Bar Mine, Ciiiltern. 
The No. 3 level in this mine is 420 feet below the surface. From 
the shaft there is a western cross-cut 120 feet long to the reef, and a 
level runs north along the course of the reef for 290 feet from the cross¬ 
cut. At this point a fault intersects the reef; the strike of the fault is 
N. 25 0 W., and dip 8o° W. The fault cuts the reef off and 
throws it 40 feet to the northward. The fault was followed northward for 
70 feet, and at this point the reef is 10 feet to the east of the fault. 
The mixed quartz and slate is 4 feet thick. In the western portion of 
the reef, which is 1 foot thick, gold shows in the quartz. From this 
level to the surface this reef is intact. 
No. 5 level is 620 feet from the surface. A reef is cut in the bottom 
of the shaft a few feet below the level. This reef is about 1 ft. 
6 in. thick, and gold shows in the quartz; the manager considers this 
stone to contain about 18 dwt. of gold per ton. The strike of the reef 
is N. 2 5 0 W., and the dip is 75 0 W. The level is driven on 
the reef 60 feet to the north and 60 feet to the south. From the shaft 
a cross-cut is driven west for 70 feet to the No. 1 reef, which here is 
1 foot thick; strike of reef N. 20° W., dip 8o° E. This reef 
appears to conform to the beds of the country rock. A rise has been put 
up 20 feet above the level ready for stoping. A level is run south along 
the reef for 65 feet, and north 55 feet. The total length of the western 
cross-cut from the shaft is 160 feet. 
The reef has been cut again where the fault displaced it, and the mine 
generally has a favorable aspect. 
The Golden Bar Extended Mine. 
This mine adjoins the Golden Bar mine on the north side. 
No. 1 level is 300 feet deep. The western cross-cut is 109 feet long 
to where the No. 1 reef is cut, and the total length of the cross-cut is 
140 feet from the shaft. At the shaft the country dips west, and the 
anticline should be a little to the east of the shaft. 
The southern level from the cross-cut is extended on the reef for 188 
feet to the south boundary of the lease. The walls of the reef here are 
about 15 feet apart, and on the eastern wall there is about 2\ feet of 
quartz and slate, and on the western wall there is a similar thickness of 
-crushing material. The walls dip west. At the end of the southern level 
the reef is 7 feet thick. In the northern cross-cut No. 1 reef, for a length 
of 60 feet, averages 1 foot thick. 
No. 2 level is 400 feet from the surface. The eastern cross-cut is iao 
feet long, and passes through beds dipping east. A leader was cut at the 
end of the cross-cut. In the western cross-cut, at 108 feet from the shaft,
