Arizona Mining News.

Wilcox Range News: A sensa-
tional strike of native copper was
made a little below the hundred foot
level of the new three compartment
air shaft last week on the property
of the Mascot Copper Company. The
strike is considered of unusual
significance as it proves a secondary
deposition of the mineral on this end
of the property.
Mohave Mineri Work on the
Banner mine, at Stockton Hill, is be-
ing pushed by Superintendent Hoff.
man. The new shaft has reached a
depth of ITO feet and is expected to
reach the vein shortly. 1t is being
sunk on the hanging wall and will
penetrate the vein at depth of less
than 200 feet. At the Summit mine
the shaft is being driven downward
as fast as men can do the work. The
big vein is showing up we'll and it is
expected that it will be the largest
shipper among all the pro 1erties of
the Needles Mining and Smelling Co.,
in the county.
Mohaye Miner: An immense
amount of timber is now being ship
ped through Kingman to the mines
of Gold Road and the WallaDai dis
trict All the working mines are now
making the openings safe and are
mining in a safe and sane way.
Heretofore many of the properties
were worked with a woeful lack of
timbering and much damage to the
property has been the result. Under
the present management every thing
| is being made safe and better results
are obtained. A large amount of
round timber is now being used, the
opinion prevailing that these timbers
are stronger than the sawed product.
Bisbee Review: Since the recent
accident in the boiler rooms of the
Tombstone Consolidated Mining Com
pany new methods have been en-
ployed and the encroaching waters
have been reduced about eighty feet.
The eight sinkers, which are an in
dispensible adjunct to the successful
working of the ten boilers were, and
vet remain on the 1000 foot level, sub
merged beneath many feet of water.
To recover these sinkers a inch air
pipe inside of the Pinch pump
column has been run to the 1000-fOOt
level, and the air being forced by the
compressor sends the water at the
rate of nearly 4,5OO,OOO gallons daily
| to the SOO-foot level, from where the
same is forced to the surface by the
big 800 foot level station pump. Thus
far under the new conditions, the un-
. wing water has been kept under
subjugatfon and constantly decreased.
1t is the intention of the mine man.
agement to continue this method Of
unwatering the underground workings
until the sinkers, or at least the cab
les to which they are attached shall
have been reached, when the neces'
sarv auxiliaries will be rescued from
their watery recluse and again put
into commission as of yore.
Yuma Sentinel: The smelter of the
Clara Consolidated Mining Company
at Swansea has been blown in and the
production of copper has begun in
Yuma county. The smelter at pre-
sent is treating 75O tons of ore pei
day and has sos men on its payroll
The output is satisfactory. At pre-
sent high-grade ore is being treated
The Clara has blocked out 3,OOO,O ,OOC
tons of ore, with practically in sight
as much more. Contracts have beer
let for doubling the capacity of the
plant so that 1900 tons of ore can b'
treated daily. The town of Swansea
is building up rapidly. Many gooC
,, buildings are being erected. Th'
town has good water supply, pumPe'
: from the Bill Williams river by th'
mining company. The mining opera
; tions of the Consolidated will adj
half a million dollars to the tax rol
of Yuma county.
