GARFIELD SMELLING COMPANl

1t will be noted that in addition to
the copper values, Nevada-Douglas
ores also contain a large percentage
of iron, making the product of eharac-
ter exceptionally valuable to the smelt-
ing companies for use as fiuXes for the
silicious ores obtained from other
camps. For this reason the Nevada
Douglas ores are in demand and often
times command a premium.
Now that the results obtained at the
sInelters have been shown in consid
cradle detail, it is well to go into the
matter of available and probable ton
mage. A thorough examination of the
main division of the Nevada-Douglas
company's holdings was made by one
of its engineers, E. P. Jennings, some
thing over year ago, and in report
submitted under the date of Dec. rs,
1906, he estimated that that portion of
the property contained 100000 tons
of ore averaging 81 per cent copper.
A second examination was made by
Mr.. Jennings in February; this time,
for the purpose of looking into the
metallurgical side of the proposition.
He submitted a series of experiments,
and, in a report to the management,
found the sulphide ore to be self-flux-
ing and capable of treatment without
the addition of iron or lime; also that
the ores which contain an excess of iron
sulphides will furnish sulphur enough
to matte the copper of the oXidized
ores. He found no difficulty in smelt
ing a mixture of sulphide and oxidized
ores in blast furnaces, using coke for
fuel and ore raw. He adds that it can
be smelted in reverberatory furnaces,
using crude California oil for fuel, il
sufficient sulphide ore is used to act as
a reducing agent for iron oxide.
In August last Mr.. Jennings made a
third examination of the main division
and confirmed his estimates on a pre-
vious occasion, by laying: Il see moth
ing from my recent examinations TO
change my opinion as to the amount or
value of the ore in the Nevada-Doug
les mine; the work, as far as il has
been done, is satisfactory in the
amount and quantity of the ore dis
closed, and if ii is continued as now
planned, the amount of ore in sight six
months from now will be very great"
In report under the date of Feb. is,
1907, several months before the Lud-
wig was acquired by the Nevada
Douglas comp4ny, Mr.. Jennings, who
had conducted an exhaustive examine
ton, reported that the mine contained
q, 900 tons of II per cent ore; 5000 tons
of per cent ore and a large but un-
known amount Of ga per cent ore.
Since acquiring the Ludwig, however,
the company has devoted a great deal
of energy towards the development of
this division, and with the most fat
tering results-results that have far
exceeded the expectations of every of
fetal of the organization. The old
levels have been extended, new ones
have been established and thereby the
available tonnage of high, as well as
low-grade ore. has been materially in
creased. 1t was recently determined to
sink the main working shaft another
200 feet. and this work has been I'M
dertaken. 1t Is to be let down to the
$50 level.
That reduction works will be built
for the treatment of Nevada Douglas
ores or the ground is a foregone con-
cluSion. The metallurgical features
have been carefully looked into, and
the management is in possession of all
the NECESSARY information relative to
the lfAthod best adapted for the sue
ces&Gl treatment of the ore; costs of
material. equipment. construction, etc.
The Nevada Douglas company owns
one of the best smelter sites in the
west, together with valuable water
rights. and there is a probability that
this site will soon be utilized. Smith
valley, just below the Nevada-D Douglas
mine, is an ideal spot for works of this
Kind, being so far removed from the
agricultural districts that there would
never be a recurrence of the expe-
rienees of the smelling concerns i'm the
Salt Lake valley, some of which have
been forced to close down because of
court decisions favorable to the farm
ers. Indeed, that portion of Nevada in
the vicinity of the Douglas
mine is one of the best locations in Ne
vada for a large smelling enterprise,
that is needed and almost
demanded by the mine operators of
western and southern Nevada Yering-
ton would be a central point and read
lily accessible from camps north and
south. The nearest railroad point at
the present time is Wabuska. on the
main line of the Nevada & California
railroad, which is a part of the Harri-
man system.
