in this mine, with q crosScut tunnel of
$50 feet and drifts run on the 35, 65,
100. eco, 800, $50 and 400 foot levels,
exposing ore bodies carrying values
from IS to $500 per ton, while in places
picked samples have assayed as high
as $500. Considerable ore is stopped
ready to be knocked down and milled.
a careful measurement of ore in sight
places it at 100000.
The last three mill runs on ore from
this mine of 100, $50 and 100 tons net
ted respectively, s52S2, $37S2 and $4,000,
an average of s32 so, S27 SO and $40
per ton. This company has about
SIS, 600 worth of tailings in reserve for
cyaniding.
The Van Duzer-Douglass Mining
Company and the Van -Tonopah
Mining and Investment Company in
tend combining on good-sized cyanide
plant for getting the values out OF the
taiIngs on the two properties.
The camp is beautifully located, and
known as the Gold Range mining dis
trict. while the present postofsce name
is Douglass.
A telephone line connects the camp
with SodaYille.
On the southern slope of the Elk
celsior range OF mountains is group
of eight claims, portion of which
adjoinS the Van DuZer-DouglasS mines.
These arc the property of f. Grassie
of Sodaville, New. and are at the pres
ent time bonded to Eastern capitalists.
Extensive ore deposits abound In this
property, and are the making of al
enormous mine, the character of ore
being the same as in the Bounce ani
Van DUzcr- Douglass mines.
The properties Of the Van Duzer-Doug-
lass Mining Company are located. at
Douglass, Esmeralda County, State of
Nevada, on the most northerly slope of
the eastern spur of the Excelsior range
of mountains, about six miles in west
erly direction from SodavilleS a station
on the Carson and Colorado Railroad, a
branch system of the Southern Pacific
Railroad Company.
The properties comprise a group of
twenty-five claims, including fractional
claims, or a total of approximately 500
acres. The elevation at the mines is 1000
feet above sea level, from which altitude
a magnificent view is obtainable for miles
OF an extensive and valuable mining area
This section, formerly known as the Sill
yer Star mining district, has taken on
renewed lease of life, and new mining
district has lately been formed and is
known as the Gold Range mining district
which embraces an area some twenty
miles square, from within the boundary
of which has been extracted n the past
fully $3.50 .0000 900.
The early mining operations in this sec
ton OF Nevada forms~an interesting part
in the history of quartz mining, due to
the fact that gold was first discovered
here.
For years the surface of the numerous
ledges was worked by leasers by open
cuts, shafts, tunnels, ETC., of limited lex-
tent, and exceedingly rich ore extracted
from the pay chutes, but the instances
are few where depths on the same pay
chutes were undertaken.
The Van DuZer-Douglass properties
comprise a series of parallel gold-bearing
quartz veins, all holding a general east
erly and westerly course, with a slight
dip to the south. The lodges vary from
one to fourteen feet in width, the entire
group covering an area two miles in
length by three-quarters of a mile in
width. A marked feature of all these
series of veins is their remarkable per-
sistency in the deepest workings. They are
traceable for a long distance upon the
surface, while the system Of dilses which
parallel the veins are strong and well de-
fined, and the veins, which are true fis-
sures with the contact features. are in
closed in porphyry and limestone walls,
the ore leaving the walls perfectly free.
The ores are generally a soft, decom-
posed quartz carrying iron, with some
sulphides (pyrite); the gold IS free and
quite fine, yielding readily to the free
milling process of battery and plate ANAL
gamation, supplemented by cyanide treat
ment Of the mill tailings, and a high ex-
traction is thus enabled.
The topography of the property and the
development of the veins Is such that a
very accurate knowledge as to quantity
of ores and the values can be obtained to
depth of 1000 feet Several veins have
been opened by shafts and crosscuts to
depth of from 100 to 400 feet below the
level of the mill These same veins are
clearly defined on the surface and have
been worked to various depths as they
extended through the property, reaching
elevations of from 500 to 1000 feet above
the mill and down the opposite side of
the mountain to about the same level.
This district was discovered in 1893 and
has been worked on small scale by leas-
ers and various owners, number of
whom took out snug fortunes, producing
in all about s40o, 900.
While the amount taken out was
large in the aggregate, the work hav-
ing been done largely by individuals
and with no capital or concerted eff
fort, was sufficient simply to demon
strate the large ore bodies, many of
the veins being simply scratched over.
