house.
On the Iron Duke, another of the
King Bee group, fine two-compart-
mert shaft has been sunk to a depth
OF $40 feet. The shaft is vertical and
as straight as plumb-line the en-
tire distance and built for use of a
cage, and started with the object of
being sunk to the Newhouse tunnel
level, with which it will be connect
ed by lateral 1856 feet in length
driven on the Wellington No. vein.
This lateral, as stated above, is al
ready driven to a distance of 709
feet from the tunnel. The depth Of
the Iron Duke shaft will be 1856 feet
when connection is made.
The surface equipment at the Iron
Duke shaft consists of 22x66 foot
building, covering the machinery
plant and head frame; a 6xS Vulcan
hoist of the H. & B. improved pat
tern; 25-horse power upright boiler
fitted with auxiliary steam-drum; a
12x12 single-stage Blaisdell air COM
pressor, belt-driven from a 50-horse
power Bullock motor; transformers
of double the capacity for present re-
quirements, substantially housed at
a safe distance from the main build
ing; a two-post head frame Of modern
construction and ample strength for
depth of 1000 feet of shaft.
The underground development con-
sists of fully 1900 (three thousand)
feet of work on the three levels Of
the mine-at 200, 300 and 500 feet
depths, the entries being through
cross-cuts from the shaft, cutting at
various levels, no less than seven
strong veins and numerous feeders, -
all pitching as depth is gained, to-
ward common point, indicating that
sufficient sinking will disclose sin
gle large vein. probably carrying in
condensed form, the scattered values
found in the numerous veins thus far
encountered. Thousands of tons of
ore, ranging in size from a few
inches to eight feet in thickness and
fluctuating in value from S2.20 to
S17S.00 gold and silver content, are
exposed in the workings on the var
ious levels, much of which will no
doubt be mined at a profit when the
proper method of treatment shall
have been devised.
The present extension of develop
ment consists mainly in driving the
cross-cut on the 500, sufficient dis
tance to the south to intersect the
footwall streak of the great yelling
ton No. vein in which the high
values are being found in the com
pany's workings from the tunnel end
That the Iron Duke cross-cut is near
ing the foot-wall vein, is evidenced
by the fact that it has lately cross
ed a "spur" or cross-vein. in which
the character of the ore is identical
this vein through the tunnel. Con
siderable additional water-flow was
also encountered at this point. From
the location of the apex, which can
be traced the entire length Of the
property, and the well-known fac'
that the vein is north-pitching, indi
Gates that less than fifty feet from
the present face Of the cross-cu'
should intersect the vein.
The improvements contemplated fol
the year 1910, are: The installation
of 50-horse power electric hoist or
the Iron Duke, to replace the hgh
steam hoist now in use, which will b.
placed on the Compensation shaft
now 101 feet deep, and which will be
sunk $50 feet more before drifting
1t is quite probable the Iron Duke
shaft will also be sunk an additiona
500 feet. A drift will be driven OF
the Compensation vein, from thu
Newhouse tunnel, at least 200 fee
to the west, at which point rais'
will be driven to work the grount
above the tunnel level. The three
compartment raise from the latera
on the Wellington No. 6 which II
already up over 60 feet, will be driv
en- an additional 100 feet, a station
cut. and blind drift run to great!
facilitate the handling OF the orr
which is now being worked througi
n small prospect raise near the en-
Mance to the lateral.
The coming year is one Of grea
promise indeed. for the King Bee
