effect that Giroux Consolidated
Mines company has cancelled its mill
and smelling contract with the Neya-
da Consolidated. This is taken to
mean that the new owners propose
to go ahead with their plans to con
struct a mill and possibly a smelter
to treat its ores. In telling of the
conditions at the Giroux mine, Geo.
l.. Walker says:
"Giroux has mined and shipped
between 100000 and 900, 600 tons OF
porphyry ore form its Morris-Bunker
Hill deposit and made very little,
If any, profit SO far. but its mining
has been almost wholly of a prepar-
atory character. The top and hang
ing wall of the ore have been mined
away by the square setting system
and a very large amount of timber
purchased and put in to form a mat
between the ore and the Gaping.
Meanwhile the ore has been devel-
oped for the caving system. While
these heavy expenditures are under
way no one should expect the COM
pany to show any operating profits.
Stopping by the caving system is
only now beginning. When all the
ore is being extracted by this method
the cost of mining will be about half

wear. Within two or three months
Giroux should be getting its ore out
at a cost of 81 to 1926 per ton and
making a profit of approximately 81
per ton on the operation.
This Norris Bunker Hill deposit is
the best ore deposit so far discover
tains about 1900, 900 tons of por-
phyry, carrying a little better than
2 per cent copper. 1t concentrates

to 73 per cent. Mining 1900 tons
daily, 1t will take ten years to ex-
haust these deposits.

LAS have pointed out previously.
the great future possibilities of Gil
roux are in its Alpha area That the
management believes this finds con-
firmation in the heavy permanent
equipment installed at the Giroux
shaft, which was sunk 700 feet dis
tant to take the place of the caving
Alpha shaft, and also in the fact that
all of the available area in the
limestones surrounding was purchas-
ed for the Giroux company immedi-
ately after control changed.
AT present the Giroux shaft is
idle. This is due to the fact that the
comapny's working funds had been
so nearly exhausted before the strike
occurred last fall that what money
there was left was needed to develop
and equip the Morris-Bunker Hill ore
bodies and begin their regular pro-
duction. The strikers called the men
off the pumps and allowed the lower
workings TO fill with water, estab-
fishing a precedent for unfair fight
ing. Never before in the history of
mining labor contests did the leaders
pumps.
There Is every geological and
neurological reason for the belief
that large deposits of high grade, di-
rect smelling ore will be found at
depths of 1000 to 1000 feet. and per-
haps much deeper, in the Alpha area.
Numerous good lunches of rich OK
ides, %carbonates and native copper
were disclosed by the workings near
and Immediately below the water
level. To sink to depth and extern
sively develop this area a great deal
of water will have to be pumped,
however, and money must be expend-
ed freely for two or three years. At
ter its ~porphyry mine is once in good
working condition Giroux should
have the needed money to spnd.
The loss of money by Giroux
stockholders is due neither IN mis-
