from the main working shafts OF the
Old Dominion and in close proximity
to the Miami. Equipment necessary
for generating power in the shape OF
electricity is on the ground and
would have been already installed
were it not for the cut in the price of
metal and the general shutdown OF
all development work. II is the In
tention of the management as soon as
the electric power is installed to open
up the Yuma and Black Oxide leads
ON their property. The present open.
ing on these leads promises consider
able to the tonnage of the Old Do
minion in a short while. The Black
Oxide lead is being opened up through
the Buckeye shaft and by leasers.
The Old Dominion company has op-
ened up thirty miles of ground in
crosscuts, drifts, tunnels, etc, and is
at the present time producing about
1900 tons per month. The past few
months the grade of ore mas been
slightly increased and at the present
time the average shipping ore is
about eight per cent About 700 tons
is being shipped daily from "a"
shaft, 100 Grey shaft and about so
from the Continental mines, &C"
shaft being sunk to take care of the
water proposition, and a large Nord-
berg hoist has been installed. The
Old Dominion company has extensive
property and there is very little
doubt in the minds of those who are
familiar with the property, that a
large proportion Of it is mineralized,
and it is only a matter of time till
t. Thar- hox Of
the finest cencentrators and smelters
in the country and the loss in Stag
has been reduced TO a minimum
where previously from two to four
per cent was lost The old Stag is
being resumed gradually and about
an average of two per cent is being
recovered In the "a" shaft on the
18th level, which is about 1,400 feet
deep extensive snlphide bodies are
being uncovered.
The Grey shaft also has extensive
sulphide bodies. At the present time
Old Dominion is running three fur
naces. Two others are idle and the
sixth. the largest of all, is In position
to be set up and put into opelation
at moments notice. No outside
sulphfdes are necessary at the mo-
ment in operating the three fur
naces, though If the other two are
put into operation 1t is possible
more sulphides will have to be
shipped IN It is only matter of
time, however when sufficient sui
phides will be opened up to take
care of the camp. The sulphide
bodies on the Grey are uncovered
mostly on the 600-foot level, and in
a WINE which is $50 feet lower
than this level. They have one
crosscut of eighty feet on the 14th
level in "A" shaft with an average
value of about ten per cent. This is
sulphide.
At the West End ore body of the
Old Dominion there has been little
development, as water has prevented
much work there. This body seems
to have dropped 400 feet lower than
the main bodies of the mine. They
have one shaft down with ten levels

untouched. This is because of the
big floods four years ago, though
within six months they viii be able
to get to it. This will be one Of the
most important developments in the
next year. The Kirkley vein, which
is opened up by the "a shaft to a
depth of about 700 feet, shows a
mineralized width of about Is feet,
carrying six to seven per cent sui
phides, and presents great possibili-
ties This vein widens rapidly as it
goes down, the outcrop on surface
being only a streak about twelve in
ches in width. 1t is opened up on
five different levels II could, no
doubt. furnish about $50 tons per
day to the smelter 1t is one of the
strongest and healthiest veins in
the district Besides the special
bodies mentioned there are consid'

bodies of no small size, and the pos
sibilities of this mine within the next
few years cannot be estimated.
Arizona Commercial.
The most active operations at the
present time at the Arizona Com
mercial are on the Black Hawk vein.
They are sinking new shaft the
Eureka 1t is down about 20 feet.
Permanent machinery is being in
stalled as rapidly as possibly, HOSTS
and composers, boilers and odl
tanks. etc. This Is three-compart-
ment shaft, vertical. The Black
Hawk shaft is down about 500 feet
at the present time and they have a
winze down about Sc feet which Is
an exceptionally good showing.
About so tons per day is being ship
ped from the Black Hawk 10 the
Old Dominion smelter, averaging
about seven per cent. Conditions
and the low price OF metal are the
reasons stated for the closing down
of the Copper Hill shaft of the Ari-
zona Commercial, and, with the ex-
ception of keeping the water down
no other work Is being done. The
Copper Hill IS working on the Old
Dominion fault and is only a stones
throw from the Grey shaft OF the
Old Dominion. The Black Hawk
shaft is connected with the Great
Eastern shaft of the Superior &
Boston. The connecting of these
two shafts was found to be a great
benefit TO the underground workers
IN allowing good ventilation and
clearing away the insufferable heat.
The ores from the Black Hawk are
high in iron
The Arizona Commercial people
have built and are operating three
miles of railroad connecting the
mines with the Old Dominion smell
ters Practically all the ores carry
considerable silver values.
