HOLDINGS.
The Giroux Consolidated Mines
Company own and operates the
Giroux property at Ely, and the
Sultana and San Jose groups %
miles southeast of the town Of
Carlo, Sonora, Mexico. The Nevada
property, the most important, and
one of the three largest mines in
Ely, comprise an area approximately
1000 acres, while in the Sultana
there is a total of 459 acres.
The Nevada property, which con-
stitutes the most important of the
company's holdings, lies between the
Cumberland Ely and Nevada Con-
solidated mines at Ely, Nevada. The
ground is well located and contains
a large pOrphyry area and also a
considerable amount of limestone,
the latter showing a high grade ore,
the only ore of note in this forma-
ton so far encountered in the camp.
The porphyry deposit, which is
analogous to that of the Copper
Flat Ore Body of the Nevada Con-
~solidated is developed by five i'm
portant shafts. At present the only
one working is the Giroux, which
pumps all of the water encountered
in the porphyry workings. These
shafts on the porphyry zone lie in a
general east and west direction and
develop a territory of 24O0 feet in
length, in which the underground
workings show the ore shoot to be
continuous for 1900 feet, to have a
width of $50 feet and a depth of
$50 feet.
The limestone ore bodies are de-
veloped by the Alpha shaft 1215 feet
deep, with levels at the 77O.s 600
and 1900 foot points. Water. at
present, is standing to within 80 feet
of the 1000 foot level making the
1900 inaccessible.
Owing to the impracticability of
maintaining the Alpha shaft as the
main hosting way, the present man.
agement is sinking a new shaft 10
by II feet in the clear, 700 feet to
the westward. The shaft is being
sunk from the surface and raising
is going on at the no and 1000
foot levels, thereby giving three
points of attack. The ores in this
deposit are high grade smelling and
resemble those of the isbee Camp.
In September 1908, a shipment
of 200 IONS of ore from this deposit
was made to the Garfield Smelter
to ascertain its commercial value.
The average of the ore was between
IL and 13 per cent. and the net
smelling returns amounted to about
$4,4O5. This is the only shipment
which has been made from the mine.
In the porphyry deposit the for
mer management estimated the ore
reserves at 100000 ions averaging
2.8 per cent. copper. In addition
to blocking out this ore into 100
foot a at the present time the
company is drilling with churn
drills to ascertain accurately the
amount of overburden, and to de-
termine whether or not the ores can
be mined by steam shovel. AT pres
ent six drills are in operation.
In the lime deposit it is some
what premature to state the size n
Importance of the shoot developed
by the Alpha shaft. There is al
ready q. considerable tonnage OF
direct smelling ore exposed, esti-
mated by the former management
to average Is per cent copper and
indications are encouraging for the
extension of the present ore body
with development.
The property is equipped with a 45O
ton concentrating mill, which was
built in 1906 and which has been
employed since that date principal
ly in testing the ore. The former
management states that the property
has sufficient water, obtained from
the underground workings, for the
operation of this mill. While Of
fetal plans have not yet been made
public regarding the concentration
of the ore the company will I'M
d%oubtedly increase the present plant
to a size commensurate with the
property's ore reserve. Tests on the
ore are stated by the former man
agement to have shown a ratio OF
concentration of 8 into l and saw
ing of 80 per cent.
The Giroux property ranks as one
of the largest in the Ely camp and
should make an important copper
producer. The property is now be-
ing quietly developed and the policy
of the present operators will un-
doubtedly be the same as that whicn
the Cole-Ryan Company have put
into effect at their various other
properties. The mine has large de
veloped ore and excellent
