found to contain many seams OF ore
~assaying we'll up into the shipping
figures, and this is accepted as an
indication that both the water and
the enrichment found in this vein
come from the same vein. which is
but a short distance to the east.
Jumbo Extension
Sinking continues from the old
bottom level, 1917 feet below the
surface. and the winze, following the
rather flat dip of the main lode of
the district, is being sunk now at
a sleeper angle in order to reach
the foot-wall side, from which the
vein can be explored to better ad-
vantage by means of cross-cuts and
raises. The vein matter is heavily
mineralized throughout and contains
seams of ore Yielding good assays.
Shipments of ore averaging iround
nine per cent copper are being for
warded by motor truck daily from
the Copper Mountain property 20 the
smelter and a substantial profit is
said to be made from this product.
New workings are opening a ccTsid-
cradle quantity of this ore, III atCi-
ton to a large tonnage of ore con-
tanning from two to five per cent

Reorganized Kewanas
Connection for air will be made
shortly between the workings of the
Kewanas company, at a depth of $40
feet. and those of the Jumbo Junior
company, in ground leased by the
latter from the Kewanas. This con-
n%ection, which will greatly facilitate
the work of both companies, will be
made near a point where the Junior
company's work has resulted in ex-
posing ore of shipping grade, near
the cross fault that cuts through the
big vein in a southeasterly direction.
With better ventilation afforded, the
Kewanas company will enlarge the
scope of it's work in its southern ter
ritory by driving a series of raises
from the south drift and southeast
cross-cut, for the purpose of explor-
ing the hanging wall of the big ore
channel.
Great Bend Mine
Ore of shipping grade is exposed
at several points in the Great Bend
mine and shipments are being sent to
the sampler of the Western Ore Pur-
chasing company, carload samples
varying from $50 to $50 per ton.
The new stope above the 160-foot
level, 35 feet east of the big main
stope, is producing ore of excellent
grade, while the ore-shoot opened by
the main stope has now been follow
ed and proved to be continuous from
the 30O-foot level to a point over
60 feet above the 100 level on the
dip of the vein. The east drift on
the 3OO-foot level is now nearing
the old Lockhart lease shaft, which
produced some high-grade ore.
Red Hill Florence
Development work at several
points has exposed large bodies of
excellent mill ore, together with oc-
c~asional seams of higher grade ma
terial. Drifts are being extended
north and south in the main Flor
ence vein and at one point a north
drift from a raise above the 500-foot
level is approaching the point where
it is hoped to pick up the extension
of a rich ore-shoot mined by lessees
in adjoining Florence territory.
Cracker Jack Mine
At the most easterly point reached
on the 320-foot level a raise is be-
ing driven from the main cross-cut
and apparently is now in the Rabbit
Trail vein, for which it has been
driven. The vein has not yet been
opened sufficiently to determine it's
value, but the conditions are pro-
nounced by the management to be
most encouraging.
