Acid Plant-Millions of Tons of Ore
From Tuesdays Daily

Among the well known copper pro-
perties in Globe district the Inspiration
is properly classed among the best.
There are twenty-one claims in the
group, situated abont nine miles wester-
Is from Globe, and adjoining the pro-
perties of the Keystone and Live Oak
companies. Undoubtedly the lnspira-
ton has the mother lode of that sec
ton and the largest of the district, it
being nowhere less than 600 feet across
and having an extreme width of 1900
feet. and covered by twelve full claims,
5000 feet in length,
The principal mine workings are on
the three or four claims near the GEN.
ter of the group and consist of about
5000 feet of crosscut tunnels, drifts and
wines. opening the vein to vertical
depth of 255 feet. The ores of the up
per levels are carbonates and oxides
assaying from four to seven per cent.
The Woodson tunnel 723 feet long,
opens the vein at depth of 220 feet,
and Wine has been sunk 80 feet be-
low the level. The ore on tbs level
and in the Wine is chiefly glance and
sulphide well disseminated thr, ugh the
ledge matter, and some of it oc eurring
in seams of varying thickness running
high in copper. The ore body as far
as prospected on tina part of the lead
is 1000 feet in width, 200 feet long and
255 feet in depth.
AT the extreme eastern end of the
propel', there is a great deposit of
carbtlA.a ere averaging about four per
cent copper and showing numerous
seams of high grade oxide and glance
ores. This is veritable mountain of
ore that could be quarried and handled
with steam shovel at low cost. A
moderate estimate of the quantity of
ere contained in this east ore body is
1000, 600 tons and it is anideal teaching
proposition. The amount of ore ex-
posed on other parts of the property is
conservatively estimated at 5000, 600
tons. About one half of the total ton
mage of ore is best suited to concentra-
ton while the other half is adapted to
teaching.
Since the Inspiration Mining compa-
ny was organized, about two and half
years ago, the property has been in
charge of J. d. Coplen as general man.
ager, and J. B. Coplen as mine super
intendent. and large part of the de-
velopment work was planned and exc
cuted by them.
The magnitude of the ore bodies de-
veloped on the Inspiration property ear
ly impressed General Manager Coplen
with the ACCESSIBILITY Of erecting a con-
centrating plant of moderate size.
Complications arising through the death
of two of the largest stockholders in the
company prevented Mr.. Coplen putting
his plan into execution for some time,
but last spsing the directors acted ia
vorably on the proposition 81 omitted

mill was undertaken and is row well
along toward complet on.
A representative of the SILVER BELT
visited the Inspiration on Friday last
and found Supt. J. B. Coplen directing
a crew of carpenters and machinists at
work on the mill, and other work men
developing water supply in the gulch
below. The mill is located on the south
side of Webster gulch, on ground re-
Gently purchased for the purpose, ard
is an excellent site, the slope of the hill
being quite steep, with plenty of fall
below the mill for the disposal of the
tailings, which will fall into the bed of
the creek and be carried away by period
ical floods.
The mill is purely gravity
system arranged in succession of ter
races. The ore will be drawn in cars
propelled by horses, over an l8-inch
track 1850 feet long, from the Woodson
tnnnel, and will be delivered over griz-
zlies at the top of the mill to the rock
breakers and thence into the bins of 700
tons capacity, From the bins the ore
VIII pass to the automatic feed and then
to the rolls. The crushed ore goes to
large Coplen sinner, where separation
of the minerals from the matrix begins.
The tailings from the sinner pass to two
compartment Hartz jigs and ten to
the Huntingtons for the final grinding
process. The entire pulp from the
Huntipgtons will be discharged through
the proper launders to another large
Coplen sinner, which is also a classifier
as to size, and all the pulp in its respec-
tive sizes then goes to the Giipin coun-
ty bumpers, where the final separation
of the minerals from the gangue takes
place, and the tailings pass to inclined
platforms and are drained of the water,
which is returned to the supply tank
above the mill to be used over again.
The mill is 200 feet in length and 36
feet wide, having nine floors, and with
the boiler room adjoining on the west
on level with the engine room. The
construction throughout is substantial,
the frame being built of 6x6 timbers
and trussed throughout. The shafting
and pulleys are carried close to the
roof, and the mill is open, giving unob-
structed view from top to bottom As
already stated, it is strictly a gravity |
