9 The Chicago Boston Mining COM
pany has under consideration the con-
struction of mill of 200 or ESQ tons
daily capacity and it will probably be
. built this summer This news will
: probably come as a surprise to most
of the readers of the Miner, for the
Chicago Boston company has been
energetically saving wood and saying
nothing for long time, hence the i'm
preston was probably obtained that
the silence of the company was due to
the fact that 1t had nothing to talk
about. This impression is quickly dis
PEELED by visit to the property, for
If the ore actually in sight at the
Chicago Boston was on Nine Mile or
Canyon creek, 1t would be the talk of
the district But being In neither of
those famous sections, but on Lake
gulch, about mile and a half west
of Wallace, outside the proven mineral
belts, 1t has attracted comparatively
little attention, and the owners having
nothing to sell, have not sought pub
licity and have quietly developed the
property to point which justifies the
construction of a mill. The company
now has the H. E. & M. mill under
lease and for several weeks has been
making tests of the ore in order to
determine just what is required in the
proposed new mill to achieve the best
results.
Results Highly Satisfactory.
While the concentrating feature of
the II. e. & M. mill has not proved
as successful as desired, nor as sue
cessflu as it could be made with cer-
tain changes, the flotation plant has
met every expectation and has con-
vinced the management of the Chica-
go-Boston that its entire output can
be treated economically by this re-
narkanie process. 1t is therefore the
purpose of the company to build strict
~ flotation mill, equipped with the
most modern and efficient crushing IA.
cilities. There is an admirable site at
the mine, and the company has an
abundance of water both for power
and milling purposes. In the mean
time while final plans for the mill are
being WORKED cut. the company may
make commercial use Of the H. e. & M.
mill If the question of cost of trans-
portation of the ore from the mine to
the mill can be satisfactorily solved.
Motor trucks are being investigated
and 1t is possible that this plan will
be adopted. The motors would still
be of service after the new mill Is In
operation to transport the product to
the railroad.
Two Parallel Veins.
The Chicago Boston has two parallel
and radically different veins about 200
feet apart and which seem to approach
each other on the east end. The
original vein, which in the early days
was known as the Tin Cup, is charac-
teristic of the dry ore belt extending
from Big creek to Lake gulch. The
ore is gray copper with siderite or
spathic iron gangue. The lowest tun-
mel has now reached a point where the
vein should be cut any day. Spots of
gray copper are frequent in the quart
zite, indicating that the vein Is near
This will give a depth of 600 feet and
$50 feet below No. 5. In No. tun-
mel an ore shoot 200 feet long and six
feet wide has been opened which will
average 20 ounces of silver. In tunnel
No. the shoot has also been ex-
plored for 200 feet, hardly as wide as
in No. 5, but of substantially the
same grade. There are streaks of very
rich ore in both levels, and shipments
have been made of several cars which
averaged 70 ounces. 1t is regarded as
quite probable that the lowest tunnel.
No. 6, will disclose a larger and rich
er body of ore and will make ship
ments direct from the mine possible.
In any event the ore is admirably

The Lead Vein.
The second vein on the property
Is about 200 feet north of the Tin
Cup and has been definitely located
for distance of 5000 feet on Chicago
Boston ground. 1t is evidently identi-
cal with the Kill Buck vein, one of the
early locations of the district and ly-
ing on the opposite side of the gulch
from the Chicago Boston, the end lines
IF the two properties joining in the
bottom of the gulch. The vein has
been intersected by two crosscuts from
No. tunnel, about 200 feet apart. In
the first crosscut the vein is fully six
feet wide, all milling ore, with a nice
bunch of carbonate in the top of the
face. The vein appears to be twisted
