Payable quartz has been mined from different parts of the Main Reef, but 
the Spur Reef was uniformly profitable to work, and the recovery of the 
lost reef is now engaging the attention of the manager . 
There are very large bodies of quartz in this mine, and excellent returns 
have been obtained in the past. The depth so far attained is but a mode¬ 
rate one, and there appears no reason why, as development goes on, this 
should not prove as profitable to work in the future as in the past. There 
is probably a long life before it. The rare mineral, maldonite (Au 2 Bi), has. 
been found more abundantly at this mine than elsewhere. 
The Eaglehawk Consolidated Mine. 
The depth of the shaft is 1,250 feet. The country rock all dips east r 
the pitch of the country is south, and the pitch of the quartz and gold 
also southerly. At the No. 10 level, 1,150 feet from the surface, a level 
runs in on a reef from a short cross-cut. The reef is cut off northward by 
a fault. The channel at this level is bounded by walls on the east and 
west sides. These are 30 feet apart, and between them is mixed country 
rock and quartz. The whole 30 feet of material, as broken out, is crushed, 
and gives good returns. At the 950-feet level, north of the shaft, there 
is a wide reef in the stopes above the level, which shows gold freely. 
This is cut off by a vertical transverse fault, and northward of the fault 
there is a width of 30 feet to 40 feet of mixed quartz and country rock, 
the whole of which is sent to the mill. The pitch of the country rocks 
is northward. The reef pitches with the country rocks, and also con¬ 
forms to their dip (east). At the 850 feet level, in a level 240 feet to 
east, off a cross-cut 90 feet to west, a quartz reef that is promising in 
appearance is being driven upon. This is the most southerly working in 
the mine. 
For years the workings in this mine were principally on the western 
wall, and nothing of a payable character was obtained. Later, drives were 
run along the east wall, and with most favorable results. There are ex¬ 
tremely large bodies of quartz in this mine, and some of them have been 
proved profitable to work to a width of 30 to 40 feet, crushing all the 
material as broken out. To thoroughly prospect and open up this pro¬ 
perty will require many years of work. In depth there are thousands 
of feet still to be penetrated. Southward of the present workings there 
is a great length of the lode that, from the surface downward, has had 
nothing done upon it. Vigorous prospecting and opening up along this 
great lode would probably lay bare extensive bodies of quartz that could 
be worked profitably, judging by the previous history of the mine. 
The Target Mine. 
Here an adit has been driven about 900 feet along the strike of the 
strata; then a cross-cut has been put in east for about 300 feet; then 
a level north 150 feet and south 100 feet. A rise of 80 feet has been 
made from where the level and cross-cut join. The reef is irregular in 
thickness, but is now being worked on a bulge. It appears to conform 
with the strike and dip of the countrv rocks. 
So far as observed at Tarrengower, the rocks appear to be dipping 
generally to the east, and this suggests an over thrust to the west. The 
shoots of auriferous quartz also appear to pitch in the same direction as 
the stratified rocks. Extreme metamorphism has taken place in the sedi¬ 
mentary beds (Ordovician), producing homstone and schists from what 
were, previous to the granite intrusions, sandstones, slates, and mud¬ 
stones.
