timbered.
On reaching the breast of the
east drift, drifting was continued to
the 367-foot point. The objective
being a point below a winze that is
said to have been sunk from the
236-foot level, which was reported
to be all in ore of a $40 grade. This
drift and raises from it failed to To-
cate profitable values. To make an
adequate stump a cross-cut 10 feet
below the 4OO-foot station was driv-
en- 80 feet to the south side of the
property.
The ground in this 400-foot level
is composed of a swelling, moving,
decomposed and wet fine-grained
andesite, which necessitates spiling,
bridging both caps and posts and
driving tagging. Incessant relieving
and replacing of timbers are COM
pulsory. The evident impoverish-
ment of this portion of the vein at
this depth, coupled with the above
exceedingly expensive obstacles,
caused the management to decide to
temporarily discontinue all work on
this level and start operations on the
236-foot level. The workings on this
level were cleaned and retimbered
- ~,,-l 81 nNrnnrf with q NrnCc-
cut S5 feet long extending from the
3OO-foot level of the old incline
shaft. The east drift was found to
be 40 feet long. The above men
toned work practically covers the
old workings found and placed in
shape to proceed with further devel-
opment.
The east drift on the 236-foot lev
ell was continued to a point due south
of the old Lockhart shaft and a
cross-cut north was driven to hat
shaft. The distance from the YER
tical shaft to the Lockhart shaft Is
9S6 feet. The productive ore-shoots
we're encountered in this east drift.
A drift west from the vertical shaft
was u a distance of $50 feet and
a cross-cut 90 feet, both of which.
after running raises, failed to show
commercial values. The above men
toned work on the 236-foot level, to-
gether with numerous cross-cuts n
raises, practically completes the de-
velopment work On that level.
In December, 1916, it was decided
to cross-cut north at the 16O-foot
point in the vertical shaft to inter-
sect the vein. The vein was found
in the cross-cut at the 1OO-foot
point. Drifting on this vein has pro-
crossed almost continuously, drift
measuring on March 81, 1918, 926
feet long. This drift must be con-
tinued easterly for about 20 feet
and a cross-cut run a distance OF
95 feet to reach the Lockhart shaft.
Cross-cuts and raises exposed two
productive ore-shoots on this level.
1t must be remembered that the
greater part of the work on the
236 and 16O-foot levels was per-
formed during the same period. The
236-foot level reached the Lockhart
shaft January IL, 1918. This shaft
was found to be Ais feet deep and
containing IS feet of water. The
collar of the shaft is 1875 feet high
err than the collar of the vertical
shaft. 1t is the intention to thor
oughly develop the ground in the
vicinity of this shaft, Is many re-
ports of the results of the old work
at bottom of shaft are very encour-
aging. With this in view, a 3O-h. p.
Hendrie-Bolthof hoist, 30-h. p. West
inghouse motor and a Cameron sink
err have been installed and pumping
will be under way as soon as posi-
BILE.
The future plan of development is
to sink the Lockhart shaft 100 feet
deeper, cross-cut to vein and drift.
The drifts on the 160 and 236-foot
levels will be further developed by
raises and wines driven al the most
encouraging points, of which there
are many.
There is unquestionably a medium
sized tonnage of mill-grade ore ex-
posed on both the 160 and 236-foot
levels, but on account of the great
irregularity and other peculiar fea-
lures of the orebodies and the re-
suits from stopping being so radical
ly different in values from estimates
based on mine samplings, it is i'm
possible to estimate the mill-ore re-
serves. The exposures of mill ore
in the drifts and raises, however,
Justify the opinion a mill of 25 tons
