Deep mining operations are ap-
preaching the point in the Goldfield
district where concrete results may
be expected and where expert min
ing authorities have long predicted
the opening of valuable orebodies.
Developments of great significance
have been reported lately in the
progress of this deep work, al
though nowhere has the work
reached the point where the best
results are to be expected. In the
Atlanta, for instance, the main vein
has not yet been penetrated at the
deepest level and in the Jumbo Ex-
tension the deep winze has not pro-
gressed to a point in line with the
rake of the main ore-shoot.
A general survey of the mines OF
Goldfield will show that the physi-
cal condition of the mines is better
than for several years past and
that high-grade ore is still being
broken at many places throughout
the district, while large quantities
of lower grade materials are being
placed in sight in the course of de-
velopment work. Work that is now
being carried to great depth is re-
garded by mining men as the most
important that has been undertaken
here for a long time past and like
ly to exert a vital influence upon
the future of mining operations in
the district.
In the future, and under more
favorable conditions that now pre-
vail, large quantities of good mill
ing ore will be mined and treated
in the Goldfield' district. War prices
have so greatly increased the cost
of all mining supplies and equip
ment that refractory low-grade gold
ores cannot be treated profitably.
The rise in price of silver and cop
per has more than Offset advances
in operating costs, making it pos
sible to work low-grade silver and
copper ores, but gold mines that
were making only moderate profit
a year ago are in some instances
unable to break even, in the face of
greatly increased operating expen-
ses and with no compensating ad-
vance in the value of their product.
War conditions have also created
an embargo on certain classes of ore
and on mill concentrate containing
base elements. and this prevents in
some districts the marketing of
ores of higher grade and of mill
products. With the adjustments of
prices to a basis more nearly nor

tion of Goldfield mines will be in

OIL INDICATIONS
FOUND NEAR
AMARGOSA
T
SURFACE sHALEs AND AsPHAL-
TUM SHOW PRESENCE OF
PETROLEUM

A discovery of oil-bearing shale
and of pools of asphaltum, thorough
ly saturated with oil, at a point
about eight miles south of
Amargosa station, on the Las We
gas & Tonopah railroad, presages a
stampede to the district and already
number of mining men have ar
ranged to make locations in the dis
trict. The oil indications were dis
covered in December by w. w. Drey-
er, son of E. w. Dreyer of Goldfield,
and samples of the shale and as
phaltum were sent to experts for
analysis.
Upon receipt of word that the ma
terials examined afforded indications
of the presence of petroleum, Mr..
Dreyer returned to the district and,
together with associates, located
three quarter-se tion claims, which
were filed on as placer locations, as
provided by the mining laws. Other
locations have been made lately and
1t is probable that the entire region
will soon be staked. The district
over which there are surface indica-
tions of oil extends along the foot
hills for a distance of 20 miles
The country rock of the district
is described as limestone, with
large beds of shale appearingl at
number of points and extending
generally in a northerly direction,
dipping to the east. The asphaltum is
found in depressions or pools and
living upon hard-pan that is saturated

creased in substantial measure. 1t
is the general belief of mining men
that in future large quantities of
low-grade ore will be treated here
by the oil flotation process.
Goldfield Consolidated
Ore of high grade is being ship
ped in considerable volume by les
sees, operating from various points
in the old company workings. This
ore has been broken for the most
part from narrow veins, followed
out from the old slopes, and is a
product that could not have been
extracted profitably by the COM
pany, as in company operations
tonnage is the first consideration.
Ore for the mill is being taken from
various levels of the Mohawk, Cler-
mont, Combination, Laguna-Red Top
and Grizzly Bear mines and large
tonnage of mill failing is being
treated by cyanidation.

BLUE BULL SACKS
H|GH-GRAOE
PRODUCT
RICH ORE IS BEING EAPOSED
AS WINE PRO
GRESSES

High-grade ore is being broken in
the winze from the 100-foot level
of the Reurganized Blue Bull com
pany, in the northern part of the
property, and the product is being
sacked for shipment. The ore sack
ed is estimated to average above
SIS per ton and the vein, which is
rather narrow but well defined, has
been followed down for over 30 feet
by the winze, yielding some assays
running into the hundreds of dollars
per ton.
The ore is rather soft, oxidized
material, some of which shows lib
eral quantities of free gold, and it
is identical in character with the
bonanza ore opened in the early
days of the district by the Simmer
one company, working in nearby
ground. The ground now being
worked by the Blue Bull company,
forming part of the Pig claim, was
at one time under lease to the SIM
merone company and the rich vein
was opened in the progress of de-
velopment work conducted by the
company.
After opening the ore-shoot by
means of an intermediate drift,
short distance above the 100-foot
level, the ore was picked up by a
cross-cut on the latter level and
winze started from this point to de-
termine the dip and rake of the ore
shoot. The ore has continued in uni
form width and value in the winze
and sinking will continue to further
prove the course of the ore, after
which the drift on the 250-foot level
will be extended to pick up the ore
shoot. The latter drift has been ad-
vanced to within less than 100 feet
of where it will probably cut the
ore-shoot, according to the com
pany's surveys.
