bodies have been entered, and in addi-
ton to these has just been cut paral-
lei ore body 100 feet farther west, be-
yond what is regarded as the foot
wall. At last account the new ore body
had been entered seven feet, and for
that width it showed values of from S.4
to 12.6 per cent copper.
The average value of the chalcopy-
rite ore opened on the 650-level UP to
this time is IA per cent copper.
Another asset of the Nevada-Douglas
company, and one of no mean impor-
lance, is an enormous deposit of pure
gypsum. Experts have pronounced it
the best as to quality they have ever
seen, and as to quantity it is virtually
inexhaustible. The tonnage has been
estimated at not less than 100000
tons. Gypsum is selling in San Fran
cisco at from s10.75 to SIG a ton, ac-
cording to grade. Allowing literally
for the cost of mining, treating, haul
ing and selling. these prices would
leave margin of not less than 81 a
ton.
Exhaustive metallurgical tests have
been made which show the Nevada
Douglas ores to be best adapted to
straight smelling, the ores containing
within themselves sufficient lime, iron
and silica to make almost {. perfect

in case ii should be determined by the
company TO build a smelling plant to
do custom work as well as handling its
own ores, the property is well equipped
with the necessary f1uxes to treat
cheaply a large amount of silicious
ores of which there is a great album

border of Nevada
Corpete With Smeiters.
With cheap power. plenty of fiuxes
and a labor cost about equal TO that of
other sections, Nevada-Douglas should
be in a position to compete not only
with the low-cost mines of the country,
but with the smelters as well.
All of the ores of this company are
self huxing, thus bringing the cost of
smelling to the minimum In the de-
velopment of the district no other syn
dictate or corporation has done more to
attract attention to a country that
promises to become a large producer of
the red metal in the future, and as the
company goes deeper the values re-
main, and this is one of the remarkable
features of the mine.
One of the most competent engineers
in this part of the country, who made
an exhaustive examination of the prop
erty some time ago, had this to say
about the mines of the Nevada-Douglas
company:
The ore bodies in the Nevada-Doug-
las occur in the limestone and are
doubtless replacement deposits, the
mineral solution having assembled
through numerous small assures and
impregnated the lines. The groupings
are massive and extend for approx
mately 300 feet by 5000 feet. in many
places covered by slide rock so the
average size cannot be determine =
1t is an interesting fact that in many
places the most unpromising groupings
on being broken into show excellent
ore underneath, and this fact makes
even an approximation of the availa-
BILE ore on the surface impossible.
ION the Douglas claim the ore has
an approximate width on the surface
OF 500 feet. locally called blowout,
but doubtless having been caused by
the intersection of the east-west and
north-south assures. This body of ore
has been opened by cross-cut tunnel.
raises and a shaft, and the principal
commercial ore SO far developed is IN
this place.
