character likely t o produce results
of the greatest Importance within
a short time. When work vas dis
continued asst year, owing to lack
of ventilation in these workings,
the ore-channel has been proved
up, shipments of high-grade ore had
demonstrated the value of this
ground, and the presence and effect
of a step fault had been determined,
cutting the vein at right angles to
its dip. Manager Darcy is now
driving a cross-cut to the west to
pick up the faulted segment of the
orebody and as the new air con-
nection provides good ventilation
Irogress in this work will be rapid
and results of value may be ex-
pected within a very short time.
Reorganized Blue Bull
The third property under the
management of A. 1. Darcy which
gives promise of early develop
ments of Importance is the Blue
Bull, on which he has been on
Quoting development work and ex-.
tracing high-grade ore for some
time past. The ore-shoot opened
above the 100-foot level and fol-
lowed down about 70 feet by a
winze is rather narrow here, but has
been yielding a product averaging
from SIS to over 5000 per ton.
Manager Darcy has now started
driving forward the drift on the
25O-foot level to cut this ore-shoot
and the distance to drive is not
great.
Grandma Consolidated
At a depth of about 730 feet the
shaft of the Grandma company
which has been progressing steadily
for many months, is now showing
mixed latte and quartz, with occa-
sional large boulders of quartz con-
tanning sulphides. This indicates
that the shaft has not far to go to
! reach the shale contact zone and
the relation of this ground to the
ore-channel in the adjoining Ke-
wanas, not far over ESQ feet distant,
stimulates the belief that deposits of
pay ore will be found in the con-
tact zone here.
Great Bend Mine
A good average Is maintained in
the assays of ore broken in the
slopes on the 100 and 250-foot lev
els. A new stope on the latter level,
east of the long 201-I stope, is pro-
ducing ore of good grade, while the
best ore continues to come from
the 12O-A stope above. Operations
in the old Lockhart shaft, delayed
while awaiting the arrival of ma
chinery parts, will be in progress
shortly and will attract much inter-
est.
Jumbo Extension
The company is developing in the
northwestern part of the Paloverde
claim, following a segment of the
vein in which early lessees found
some good ore. Lessees continue
shipping in considerable volume
and some of the ore has been of ex-
cellent grade, carload lots averag-
ing over 500.
Cracker Jack Mine
Development work is being con-
Quoted in a systematic manner and
the results obtained recently have
been of a most encouraging char
acter, particularly in the drift and
two raises that are exploring the
east vein on the 32O-foot level.
Many samplings of the ore have re-
turned over $40 per ton, while some
have run well into the shipping
grade figure, even as high as $40
per ton. 1t is probable that a winze
will be sunk shortly to explore the
point of contact between the two
main veins.
Silver Pick Cons.
Work has continued on the $50
foot level, where many good assays
are being obtained, but the general
average of the quartz continued too
low to market profitably. 1t is re-
ported that the company has decid-
ed to sink its main shaft, already
100 feet deep, to an additional
depth of 400 feet to explore the
contact west of the big fault.
