HAS 400 MEN NOW
DOING MINE Development WORK
Preliminary Survey For
Railroad to Mine and Con
centrator Is Completed.


Globe Arfz.. June inspiration
Consolidated Copper company is en-
ployins about 400 men in development
and construction work and the num-
Der is being increased Three develop
ment shafts are being SUNK TO greater
depth. the work being done by con
tract Jack McIvOr has the contract
for Live Oak shaft No = "a -
for shaft No. j, and JACK HaIIill5 Ton

Ore from drifting and raising is pc

near the Inspiration camp LlinDeIeo
shafts viii first be sunk and Jnen me
shafts viii be concerted, beginning al
the bottom and working to the surface
The contract for this Work mas not yer
been let. but it is expected that 10 VIII
be in d few days The grading Ior the
1900 ton concentration has not YET Deen
started as there are some details that
remain to be settled. but engineers are
working on the plans and surveys

Drill Hole In Good ore.
At the Miami mine. diamond drlu
hole No. ! is now 1z5 feet below the
$40 foot level and has been in ore Of
commercial grade for the entire dis
lance This is considered TO be a very
favorable indication that the ore de-
/ post extends TO greater depth Ihan
has ever been estimated Al previous
/ estimates Of developed ore reserve have
allowed ore for a distance Of only 50
feet below this level. If other holes
prove up as well as this one, a large
tonnage will be added to the last OF
[ fetal estimate OF 1SOO0,OO0 tons The
! erection and equipment Of the talllns
elevator at the concentration is finished

and the height of the failing dam is
being increased The total mum Der OF
men employed about the mine and mill
is about 500. one churn drill IS IN Op-
Grafton exploring and developing the
northeastern part Of the property
On the Schultze group Of claims,
three miles west OF Miami and under
! option to the South Live Oak Devel-
Opment company, churn drill hole No
] is $40 feet deep in granite formation
carrying q considerable amount OF car
Donates Of copper Carbonates were
first encountered at a depth Of 435 feet
and at a depth of 455 feet chalcOc1te
was encountered and the samples have
: since shown amounts OF these miner
ais The chances are considered favor
able for striking chalcOcite again with
in the next 100 feet. Manager L D.
Mcclure is highly pleased with the
results thus FAR attained, inasmuch as
the hole is stin in the oxidized zone
and chalcOcite was not expected at that
depth Remarkably coed time has
thus far been made with the drilling
and the management is TO be com
mended for the expedition with which
the work has been conducted
Black Warrior Shipping.
At the Black Warrior mine, near
Miami, =. s. Tate and the Lyle broth
ers are leasing on the first level and
shipping copper silicate ore TO the FL
PasO smelter. The Warrior Copper
company is employing ABOUT 10 men on
the fifth level and shipping about two
cars per week to FL PasO- The showing
on the fifth level is reported to be
very favorable for the development OF
a considerable tonnage Of ore. Ship
menIS from TINS mine have been aver
aging about nine percent copper.
Churn drill hole No. o. on the Barney
gorup. is 6l5 feet deep and has passed
out of the dacite into the schist fOrma-
ton Considerable difficulty has been
experienced because Of caving OF the
hole.
Three churn drills are in operation
on the property Of the Southwestern
Miami Development company which
lies to the southwest of and adjOins
the Live Oak mine. The holes are from
200 to 500 feet in depth and il is not
expected that ore viii be encountered
yet for several weeks. Much trouble
has been caused by caving Of the
ground into the drill holes.
Copper Hill shaft Retimbered.
The Copper Hill shaft Of the Arizona I
Commercial mine has been retimbered
down to the fourth level and drift
Is being run on that level to connect I
with drift from the Gray shaft Of the
United Globe mine of the Old Dominion
company.
The southeast crOsscut on the 1900
level of the Superior and Boston mine
Is being steadily advanced and is re-
ported to be breasted in very favorable Z
looking ground containing consider I
able amount OF quartz and limOnite
ore is being shipped from the stope /
below the sixth level on the Great [
Eastern vein. About 20 cars were
shipped to the Old Dominion smeIter I
during the month of May About 55 I
men are employed
At the Copper Reef mine, Is miles l
south Of san Carlos. the face of the I
main crOsscut tunnel is being advanced I
and is now in over 1000 feet The
drift from this tunnel. on the Califor- 1
MA yeins is in so feet from the tunnel I
and breasted for its full width in vein /
material consisting mostly of red hem
dtlte ana clay gOuge. The new air I
compressor is giving excellent service I
ana air drills are used in both head /
