NEW ESGLASD COPPER company
This company. whose hcadquarter
are in Boston. j. under the manage
mcnt OF y. =. Ayling. who has kept
force OF men on development work 10
the past two year.. The group com
pri.c7 twenty-five claims. located OF
the west side Of the san Franci-c,
river, about five miles northwest from
Clifton. The main camp OF the min,
is at a point on the mountain nearly
1000 feet higher than the river anC
two miles distant therefrOm. Beside.
the mining claims above mentioned
this company has 400 acres Of ground
on the river. where the main Office and
supplies are, the plans being in the
near future TO erect a smclter and con-
ccntrating mill at this point and CON
struct an aerial tramway from there TO
the mine. The consummation Of this
plan will be- preceded by the building
Of a railroad form Clifton to the
smclter site.
The mineral holdings OF the group
cover about 5000 feet OF the strike Of
the vein, which takes northeast
southwest course through granite
country rock. The vein, however. i,
largely within porphyry dixie and in
contact with "A granite fOOtwall. The
porphyry dixie here is from - to 30
feet wide, which is considerably min
eralized oIt7ide OF the principal vein.
The main vein, which is well defined
and solidly mineralized, is from five to
six feet wide and is we'll opened to
depth OF 500 feet and for distanc, OF
600 feet longitudinally. The ore here
comprises Il copper glance, red oxide
Of copper and chalcopyrite, much Of it
running as high as 80 per cent. copper.
the average grade being over 20 per
cent. This is a high average, but
when one secs the ore he is not dis
posed to question the figures. The
glance and red oxide were strongly in
evidence at the surface. At Il depth
Of 500 feet there is still large
amount OF copper glance, but il is .
there accompanied by the pyrites. /
The mine is developed by means of a
2,00O-foot tunnel and two shafts which
are 100 and 500 feet deep respectively.
The tunnel starts in "A ravinc and takes
n straight course along iI'a-~..-i's- or
the vein, in Il northcastcrly direction.
The 800 foot shaft intersccts the tuu-
mel at 300 feet depth and at point
about | POO feet northeast Of the tun-
mel entrance. The 40O-foot shaft sinks
on the vein about 500 feet further to
the northeast, with which the tunnel
will soon he connected. From the
first shaft levels have been run on the
vein in both directions; and similar
work has been done to some extent
from the second shaft. At both shafts
the hoisting is done with engines,
which also operate dynamOs, the latter
supplying the currents by which Dur
kcc electric drills are operated. Practi-
cally all this work has been done with
Durkce drills in Il satisfactory manner.
At the tunnel level in the 800 foot
shaft is also stationed Il gasoline en-
glne which docs the hoisting To this
level ~ the sinking proceeds below
500-foot level. The exhaust pipe
reaches to the surface and in this way
the vitiating of the air in the vicinity
of the engine il avoided. The inten-
tiou is to drive another tunnel which
will cut the main vein $40 feet below
the one already driven. The first 200
feet Of this will he II crosscut and
thence on the strike of the vein. The
farthcst shaft will be reached 5000
feet from the tunnel entrance. The
shafts have been only for development
purposes and for ventilation, as eventu-
ally the principal work and all the ore
shipments will be through tunnels,
and there is opportunity here To OBJ
tain great depth by such tunnels. y
large tonnage of ore is to he seen on
the various dumps. which MIR. Ayling
states is worth at least $500, 900.
THE CLIFTON CONSOLIDATED.
There are about sixty claims in
cluded in this company's holdings, !
which almost surround the New Eng
land group, and there are two bases OF /
operation. The principal camp is /
northeast OF that OF the New England, |
the other one being southweat of it. |
Tho Clifton Consolidated and the New !
England are on the same belt OF ore, !
aud to follow same in a southwesterly
course would lead into the well de-
veloped mines west of Chase creek.
