The Arizona copper camp., 1916-08-18

I end of June IA were under construc-
| ton.
In the tungsten mining camps the
| excitement that followed the increase
of prices was similar to that caused by
important gold discoveries. Nederland,
| Colo, little village of two or three
| dozen homes, suddenly became town
| of 5000 or more inhabitants. East Of
| Nederland two settlements, each con-
| tanning several hundred people, sprang
into existence. Atolia, Cal, a camp
of 60 or 80 people, grew to more than
a thousand.
| In the Boulder region, Colo, 10 mills
six of which were new, were in oper-
| alton Besides these at the end of June
| five old mills were being overhauled
| to work on tungsten ores and three
| new ones were under construction.
| Coupeland property, in South Boulder
| Creek, to work ores that have hereto
| fore given much trouble owing to the
| fineness of the particles of ferberite,
which are spread through horn rock
| Fifteen jigs are reported to have been
| operating on old tailings piles and on
| ings, the concentrates were sent to
| Whitley tables. All mills and jigs were
| operated by electric power, and so
| great was the demand for motors that
the stocks in Denver were exhausted.
| In Arizona four mills were erected
at Dragon, three at Arivaca and one
| at Yucca.
| In California two mills were re-
ported under construction near Goffs
and one near Nipton. At Atolia the
mill of the Atolia Mining Co., was
| burned but was rebuilt and enlarged.
| A smaller mill was operated at Johan-
nesburg, and many kinds of machines
desert debris between Randsburg and
| Atolia.
| In Nevada a mill was constructed
| and operated near Toy, Humboldt
| County, and four or more mills were
| constructed in the Snake Range. IN
which tungsten deposits were found
through a length of so or more mills.
| The United States Tungsten Corp.
/ operated the mill built a number of
| years ago by former owners of the
| property at Tungsten, II miles south
| of Osceola and a small mill was oper-
ated on the east side of the range.
Most of the deposits of the Snake
Range are said to be of low grade.
A mill was also operated at Round
| Mountain.
Tungsten mining was started as a
new industry at Silvermine, Madison
| County, No. and small quantity of
scheelite was mined at Long Hill, eight
miles north of Trumbull, Conn. The
mill on the Long Hill property, was
burned and operations ceased for a
| time. In Washington a mill was un-
der construction on Tungsten Noun
tain, 35 miles northwest of Oroville.
One of the most interesting develop
ments of the year was the beginning
of production of scheelite from con-
tact t-metamorphic deposits. Two of
this sort near Toy (Browns) New,
! were exploited and near Bishop, Cal,
mills of 80 and 100 tons were erected
on similar deposits. Other contact de-
posits were located few miles south
| of Bishop. 1t is thought by the BIZ
shop mill owners that their claims can
be worked profitably under such prices
as were paid before the war. Tung
stem minerals added largely to the
receipts of gold mines at Lead, S. D.,
and White Oaks, N M. 50 a,
The prophecy made by the Geological
Survey several years ago that the pro-
duction of tungsten ores would prob
ably be greatly increased with an in
crease in price, and that new deposits
equal to those known might be found
has now received abundant confir-
nation.
The consumption of tungsten in the
United States was even greater than
was indicated by the ores produced
for all parts of the world free from the
control of the warning European ma
tions were drawn on for supplies and
during the first five months of the
year 1850 tons of tungsten ore valued
at $3,449,311 were imported. The June
imports were probably equal to the
average of the five preceding months
making the total for the half year
1924 tons, valued at $4,139,00O.
Some of the ore imported is known
to have been of lowgrade but con-
; siderable quantity carried more than
60 percent tungsten trioxide, and prob
ably the average was not far from sc
percent WO-3. Most of the ore came
from South America-Peru, Bolivia,
Argentina, and a little from Brazil
but some ore came from Japan and
Mexico
Some of that imported, like a little
of the American ore, contained phos-
> phorus, arsenic, copper, and other
harmful impurities, but during the
height of the demand even this ore
was readily bought. BY June buyers
