-, EW copper hines In the west
attracted more attention during
the year than the Nevada Douglas
n Copper at Yerington. Nevada. Few
conner mines have made better pro-
cress in the way of development and
Jaw. IL any, have a brighter outlook
for the future Indeed, Nevada Doug
,as has become classed as one of the
really great copper mines of the world.
1t has an enviable record of produc-
ton to its credit; yet the tonnage
moved to market this year has been
only the orc encountered during
regular course Of development; only
that which had to be moved to avoid
interference with advancement of
work.
1t has been the policy Of the Neva-
da Douglas to devote practically all
energy towards development and to
the equipment of the mine for econ
cmic operation in the future. 1t has
been systematic campaign Of pre-
paration that has been going on. In
The near future. work will begin on the
building of spur Of standard gagged
track from the main line of the Ne
vada & California railroad, which is
portion of the Hartman system,
and this will be followed by the con-
struction of larger reduction works for
the treatment of the ore on the ground
Hence, 1t will be seen, big things are
in store for the Nevada Douglas COM
pany; some great work has been
planned and Will be carried out dur
ing the year 1909.
LARGE TONNAGE IN SIGHT.
While only a small portion OF the
Nevada Douglas companys domains
have been explored, it Is claimed by
engineers that there is actually in sight
nearly 100000 tons Of ore averaging
60 per cent copper; how much larger,
the resource really is, remains for de-
veloplnent to disclose. But the greater
portion of the body referred to in the
foregoing AVERAGES nearly 50 feet in
width; 1t is known to be more than
800 feet long and has been proved to
have 700 feet depth. Shoots OF extreme-
~ high grade ore run through this
body; the average value or the ore
mined from several OF the leading cop
per mines of the world Is less than
per cent copper; but the general aver
ago of the Nevada Douglas ores is
much higher than that, which gives it
distinct advantage over other copper
mines in the country.
HAS AN ADVANTAGE.
The advantage has apparently been
scarcely realized by the mining world.
Tho character and extont OF the Me-
vada Douglas ore bodies have not be-
gun to be appreciated. Mining men
evidently have not believed that the
extraordinary values could hold out.
But they are holding out, and the rich
eat ores are being found on the lower
levels.
Here Is what it means: Say that the
cost of producing copper, by the mine
whose orc average runs 9 per cent, is
cents a pound--Nevada-D Douglas
with its great ore body of So per cent
copper ore can produce the metal for
cents a pound and yet have a good
margin for handling the ore, over VIII
the other producer has.
The Nevada Douglas Copper company
owns 80 claims in u compact group
IN the heart of the Ycrington district.
1t owns also so acres of ground three
miles away in which are several good
sized springs, providing plenty Of wa
ter for mining, milling and smelling
purposes. The mine is equipped with a
2S0-horsepower compressor connected
with the. electric power line of the
Truckee River Power company, which
company is capable of supplying at a
reasonable cost all of the power that
can be possibly needed by the mines
of the district. On the property are
three hoisting plants, machine shops,
assay office and other buildings and
equipment necessary for mining on an
extensive scale.
ABOUT THE FORMATION.
The formation of the company's
group of claims comprises a large de-
post of limestone, cut at intervals by
porphyry bikes. On the northern end
is big porphyry-lime contact while
on the southern end the limestone
