DEVELOPMENTS IN THE GLOBE
DISTRICT.

important news Of the week in the
mining industry of this district has, Of
course, been the strikes made mt the
Iron Cap and Globe Consolidated mines.
II has been learned that the vein on
the 400 level of the Iron Cap IL the
west end of the Black Hawk fault and
there is little doubt that it proves up
the country between the western work
ings in the Black Hawk of the Arizona
Commercial and the Copper Hill group
of the same company. A general sam
pie taken from the west drift assayed
a. per cent copper, the sample being
taken from the face Of the drift eight
feet wide and FIVE feet high. This IL
considered an excellent showing. A
few feet from where the sample was
taken sulphide ore was encountered in
streaks in the bottom of tne drift and
IL IL now believed that the drift 10 on
top 81 good body of sulphide ore.
Picked samples assayed 81 per cent
copper, and 20 per cent sulphur with
enough iron 10 make il an excellent
smelling ore. The National company
expects to sink a Wine in the ore and
is now figuring on sinking a new work
ing shaft, as the present one IL over
600 feet from the vein.
The striking Of ore in both the Nal.
lory and Gem shafts Of the Globe Con.
solidated during the week were very
encouraging TO the company and local
stock holders. Two feet Of ore were
struck in both shafts and the grade is
almost identical, both being heavy sui
phides, although low in copper values
The north crosscut in the Gem shaft
il now something over 400 feet from
the shat, and the Future Copper vein.
which was twenty-five feet wide on the
500 level, should be struck within $50
feet.
Three furnaces have been in opera
ton at the Old Dominion smelter since
Monday and il is likely that that
number will be kept in operation for at
least n month before the two remain
ing ones are again blown in. The out
put for February was approximately g..
225,000 pounds, considerably lower than
that Of January, owing TO the fact that
but two furnaces were in operation
during the greater part Of the month
Furnace No. o is now being installed,
room having been made for il by the
moving Of the converter stands further
south. The work Of installing the new
furnace will be slow, but IL is thought
that IL will be ready for blowing in, in
four or six weeks. The new ore bins
for the smelter were also placed in
commission during the week. There
are nine additional bins, eight large
ones and small one, and they increase
the smclter bin capacity by about 20
per cent.
That only three furnaces are in Cd.
GRAFTON is due to the inability to hoist
sufficient sulphide ore TO keep the full
battery going. At present there is lit.
tie room for both development work
and mining at the same time in the
lower workings and necessarily slow
progress IL being made Good sulphide
ore is being stopped in the foot wall drift
west on the 10th and the drift is being
extended az IN the drift east and the
crosscut to the main shaft, but the
erosseut to discover the other veins
has been temporarily discontinued. No
further progress has been made on the
18th level, where the Buffalo vein was
encountered ten days ago. The ground
which caved in is being caught up and
drifts are being run in both directions
along the footwall in hard rock TO pre.
vent a recurrence Of the cave in.
