Globe Silver Belt.)
Conditions in the local mining field
have continued to improve steadily |
and il is no exaggeration to say that
Globe district has made a greater ana
more substantial advance during the
past eight months than any other min
ing district in the west, with the pos
sible exception of Butte, Mont.
The marked improvement in the Old
Dominion mine and the increased out
put of copper by that company, the
development by the Miami Copper
company of an immense deposit of low
grade sulphide that promises to make
one of the great copper mines OF the
United States, the opening of a very
large and high grade ore body by the
Warrior Copper company and the i'm
portant developments on the Black
Hawk vein, on which the Superior &
Boston Copper company is opening
one of the finest ore bodies yet found
in the district and the Arizona Com
mercial Copper company has resumed
the development of the same rich vein
on the Black Hawk mine, furnish
abundant reasons for the expansion of
! mining here and the greater attention
! that Globe is attracting in the imam
| cial centers of the country.
| There are at the present time
greater number of mining men here
examining mining properties ana rep
resenting large capital seeking invest
| ment than for many months previous.
The Great Eastern Ore Shoot.
! The developments on the 4S0-foot
| level of the Great Eastern mine, OF the
| Superior & Boston Copper company
have been of greatest interest among
| the occurrences of the past ten days.
The ore on that level which had been
running about 10 per cent copper
| gradually grew richer IN the east drift
| as the opening advanced and for the
past week the whole drift has been in
| carbonate and glace ore that averages
| about 80 per cent copper, and is PROB
ably also richer in silver, although no
assays for silver have peen made re
Gently, the average silver value on the
430-foot level being over I'VE ounces.
Yesterday afternoon the ore body in
| the east drift had widened to tweive
feet but carried less glace.
The importance of the development
in the east drift is not alone in the
very high grade of the ore, but also
the fact that the ore has already been
oDened thirty feet further east than
where it pinched on the level above,
giving the ore shoot on the $50 lever
! a present length of $50 rect ana an
average value in copper of about Is
per cent. On the 1870 level stope has
! been opened to the end line of the
Black Hawk mine, 260 fIer In length;
the width of the ore body on this Level
I is from ten to fifteen feet and the
stope has been carried six sets high
! in places, all in carbonate ore hat
averages about seven per cent. The
value of this ore body as far as opened
is already much greater than the cost
of the property and development to
date.
Ore shipments from the Great East
ern mine average forty tons daily, but
could very easily be increased to 100
tons About eighty tons of the richest
ore has been taken from the east drift
and will be shipped to the FL Paso
smelter.
The Gardner shaft OF the Superior
& Boston is nearing the 400-foot lever,
at which depth a crosscut will be run
to the south to intersect the Black
Oxide and Iron King lodes on which
important developments are looked
for.
| There is now no doubt but that the
Superior & Boston will become one OF
the important producers of Globe dis.
trict.
Il Arizona Commercial.
The Arizona Commercial Copper
company has actively resumed deye1-
opment work at the Eureka shaft,
! after having installed the necessary
equipment, Including pumps OF ample
capacity. to sink to a depth of 1000
. feet. Sinking was resumed on the Sth
! instant, and General Manager Bonnie
expects the shaft to reach the 600-foot
level and be in good ore by September
80. Il is also the intention of the
|. management to further develop the
vein near the east end of the Black
; Hawk where they have the same rich
ore shoot that is being opened on the
Great Eastern The old incline shaft
and the Eureka shaft, which are 900
: feet apart, are connected on the 500
/ foot level by drift which is in the
: ledge the entire distance This Ieyel
! | is dry and the values largely leached
! out. but at the east end a winze fifty
t feet deep to water level is In high
3 grade carbonate and glace ore, and the
e management feels confident of findine
: the same class of ore at 625 feet, wnsr
r a level is opened at that depth.
FL The success of the recent $500, 00I
4 bond issue gives the Arizona CONNER
: cial ample funds to prosecute devel
opment on the Black Hawk lode ant
for the erection of smelter, which
has been determined upon.
Quietly and persistenly Superintend
ent e. M. White of the Warrior Cop
per company has continued the de
: selopment of the Montgomery lod,
: and now has one of the most promis
r ing among the newer mines in GLOBE
, district. In fact the Montgomery a,
+ far as developed shows the larges
q ! high grade ore body IN any m-ne ey
G cept the Old Dominion. Recen -
e veiopments have exceeded the exs &c
tations OF the management. The cross
