The Eureka sentinel. [volume] (Eureka, Nev.) 1902-current, 1907-10-19

NSPOnueht Oh the Ely Mining Record
visited the Newark mining district.
where operations have been conducted
INCREASINGLY for more than 40 years, and
contributes the following article of his
observations in that locality:
The district lies along the eastern
slope OF the Diamond range on the west
side OF Newark valley. and is reached
by a 40 mile drive northwest from Ham
ilton. or an Smile drive northeast from
Eureka. While located near the west.
ern edge of White Pine County the
business of the district is done through
Eureka, as it is the nearest railroad
point. The wagon road out from Eure-
ka climbs an easy grade for about nine
miles to the summit which approx
mates the county line between Eureka
aud White Pine Counties. From there
the decent to Newark valley commences,
which is reached in about six miles.
The valley extends northward about 20
miles to Bald mountain aud the north
west corner of this county. while the
south end Of the valley is known as
Pancake valley. with an imaginary
dividing line between them.
The Bay State Property
The oldest mine in the district is the
old Bay State mine, now owned and be-
ing operated by the Newark Mining and
Milling Company. The property is 10.
Gated in chihuahua canyon, about one
mile from the mill. The group on the
north side Of the canyon is developed
by an adit tunnel about 800 feet long,
which gains a depth equal to its length.
Inc ore is found in a assure in the lime
aud Is a white quartz stained green aud
blue with copper oxide and silver bro
mide. carrying values in lead. copper
and silver. The assure is a north and
south strike cutting the formation and
has been found to be from two to 30
feet wide, with the ore occurring in long
shoots from which many thousand tons
have been produced, most Of it having
been treated at the old mill, with the
total production estimated at 81, 800. 600.
The present company is taking out good
shipping ore and are also accommodating
a large noun of milling ore which is
being sent to the mill.
A lead vein which is intruded be-
tween the bedding Of the lime in the
upper workings carries high values in
lead and silver, aud one exposure of the
ore is five feet thick. In the lower
workings to the east of the quartz vein,
lead ore has bsen opened which is be.
lieved to BE- the same vein opened above,
but has not been prospected.
That part of the property lying on
the south side of the canyon is develop
ed by a double compartment shaft 400
feet deep, with an extensive system Of
levels from which large amounts of ore
have been produced, but no work is be-
ing done there at the present time al
though good ore bodies remain in the
old workings. The shaft house is equip.
ped with a hoisting plant and an air
compressor. with an air line extending
to the workings across the canyon.
The mill was a 20.stamp amalgamat-
ing plant with a teaching process in
addition. The company has done away
with the teaching pans and installed
Wi'fey tables and Frue tanners and
has reconstructed the stamps.
This mill is said to be the the first
one ever operated in White Pine County
and was built in 1866, and after the
silver discoveries at Hamilton a large
production Of that camp was treated
there.
Water for the mill is obtained in
Water canyon, the next one to the north,
where the company owns extensive
water rights far in excess of the needs
of the mill.
Almon Day. n of the heavy Eastern
shareholders. has been giving his per.
sopal attention to the work at the mnie
this Summer, assisted by @. NJ. Perry,
the manager, and W. II, wainwright,
the superintendent.
The Meister Group
Two miles south from the Bay State,
Oh Newark mountain, Joseph Meister,
a pioneer of the district, has a group of
four claims which have been extensive
ly developed by tunnels and drifts ag.
gregating more than a mile in length.
from which $4,000 has been produced.
The ore is lead silver carbonate show
ing considerable galeua and carrying
some gold and copper and occurs in a
fault. hssure in the lime which can be
traced the length of the mountain. a
distance of about six miles, and which
has been opened in adjoining properties
on both sides from which good ore has
been taken.
The assure has been cut by four
tunnels, No. l being 100 feet to the
assure which it taps at a depth of 100
feet; No. 2, $40 feet long, 220 feet be-
low the first No. 3, 700 feet long, 1870
feet under the second. aud No. 4, which
caught the fissure at 1900 feet from the
portal and 800 feet greater vertical
depth than No. 3, or more than HOO
feet below the outcrop of the ledge.
The footwall dips to the east at an
angle of 80 degrees from the vertical
