LAeUNA SHAFT IMPROVES

New construction work on the prop

cludes a storage battery plant with an
average load capacity of $500 horse
power. electrical supply storehouse
and repair shops, assay office and lap-
oratory railroad roundhouse, ore bins
for the Laguna and g. complete fire
protection system with extensive hfe
mains and reservoirs on Columbia
mountain. The storage battery plant
will be an important adjunct to the
companys plant and is expected to
effect large economies in operating.
Under present conditions the main
supply OF power, coming from the line
of the Nevada California Power COM
pany and brought from Bishop creek,
Cal, is frequently Interrupted by cleo
trical storms in the White mountains
through which the line passes. with
the new storage and regulating plant
the company will be enabled to con-
tinue operations with all hoisting ma
chinery and the lighting of mines and
mill for several hours following such
an interruption, and under ordinary
circumstances repairs can be made
and the supply resumed before the

PLENTY OF WATER
The July production of the Console
dated was below the normal owing TO
the shortage of water, which has
caused embarrassment in ore reduc-
tion for some time past. This dl1Il-
Guilty has now been overcome and the
mill will soon be treating an average
of around 900 tons daily, bringing She

not fully, the high record figures. In
July the company treated 21,SO5 tons,
the gross value of which was $3.50, 634-'
Total costs and losses were $256,6l9,
and net profits $574,015. The ore aver
aged $3.50 per ton in value and 'the
item of costs included $4,000 which
was charged against new construction.
Development work in new ground ag-
gregated 2520 feet and discoveries of
new ore were accounted less than usual
of late in proportion to new headings.
The I.aguna shaft is rapidly being
prepared for heavy extraction and will
probably be eventually one of the most
important avenues for production of
the mines. From this shaft the con-
nection has been made with the Cler-
mont workings on the 600-foot level,
and large ore bins have been installed
at the collar of the shaft and in the
stations. This is the largest of all the
Consolidated shafts, having a separate
compartment for pumping operations.
There is a strong flow of water in these
workings which has heretofore been
handled by the air-driven station pump.
but now that the shaft has been con-
nected with the Clermont the water
will be carried by gravity to the 600
foot station of the Clermont shaft and
hoisted by means of the powerful cleo
tric pump at the latter shaft. The ore
r.
point not far from the Laguna shaft is
said to be one of the most valuable
opened since the main Clermont lead
was found at depth. Owing to the fiat
dip of the Red Top vein it was deter
mined by the management to continue
sinking the old Laguna shaft in order
to explore this vein at depth rather than
to sink deeper on the Red Top, further
to the west. This decision was reached
after the ore had been found in the
Red Top vein in the northwest lateral
from the Clermont. Some good ore was
exposed over a year ago in this vein
at a depth of 712 feet in the Hazel lease
shaft on the Miss Jessie claim of the
Laguna.
FLORENCE GoLDFIELD
The Florence Goldfield company is
treating from 40 to $50 tons of ore
daily, and while the product has been
below the desired grade for some time
past the mill has made a fair profit
and recent developments give promise
of large tonnage of excellent material
even above the 350-foot level. Within
a short time the work of enlarging the
main shaft by raising from the 5OO-foot
level to the surface will have been COM
pleted and the shaft will then be sunk
to the 10OO-foot level with stations at
intervals of fifty feet. Below a depth
nf fa OraIxy NJ
of Florence territory that has been
developed and there is every indication
that the ore bodies exposed will be
found to continue to great depth.
During the past two weeks new de-
velopment in the vein from which the
rich ore was taken on the famous
Reilly lease has exposed a large guam
tity of good milling ore, together with
seams of the characteristic high-grade
of this section. Manager Willis Law
renee has introduced a number OF i'm
provements in methods of operating
and is achieving excellent results One
of the best and apparently largest ore
shoots ever exposed on the Florence
was opened by the old Rogers -Syndi-
cate lease, south of the main workings,
and was developed to a point sixty feet
below the 500-foot level by a winze.
AS this method of extraction was too
costly, however, this deposit has not
been touched and will be sought by
driving from the main shaft at greater
depth.
Developments during the past month
in lease workings on the Spearhead
are regarded by mining men and geol-
ogists as among the most notable of
recent times in the entire district. A
vein Of iron sulphide ore, carrying gold,
silver and copper, has been exposed on
the 250-foot level of the Knickerbocker
lease and is said to be fifteen feet
wide in places and has been followed
for over thirty-five feet. The ore is
almost pure metal, yellow pyrites of
iron, some of it containing hardly any
quartz or other rock. 1t is essentially
a smelling ore, and the latest samples
have been running as high as $50 per
ton with II per cent copper. from $40
to SIS gold, and the balance silver The
ore is unlike anything else found in
the district but the vein is of large
size and apparently continuous. The
find has had an immediate effect on
the adjoining Merger Mines company's
properties-the Blue Bell, Lone Star
and Grandma.
Combination Fraction has suffered
by the long drought and inability for
a time to secure an adequate water
supply for it's milling operations. The
trouble has been practically overcome
by piping water from abandoned shafts
on Consolidated ground and the leased
mill is now treating above so tons
