TOHN A. PERCIVAL of New
York. president of the Callahan
Zinc-Lead company left on the
Northern Pacific Monday morn
ing after having spent about 10 days
in the district. In addition to giving
much attention to the affairs of the
Callahan company, with which he ex-
pressed the greatest satisfaction, Mr.
| Iercival completed all arrangements
for continuing the development of the
Chicago Boston, control of which he
holds under option. He made a thor
ough inspection of this property and
expressed the utmost confidence that
| IL viii prove TO be one of the great
mines of this great mining district
The showing at the mine fully iusti-
fies his optimistic prediction At this
time work is confined to the 200 shaft
level where a shoot of lead-silve ore
has been developed 200 feet in length.
The drift on this level is still in ore
and will be further explored as soon
as the cave which has caused consid-

this level also a crosscut is being run
south to cut the Kill Buck vein. This
is also under option to Mr. Percival
and promises to prove as valuable as
the Chicago Boston proper
Continue Sinking.
Upon beginning development of the
Chicago Boston, Mr.. Percivars orig
inal plan was to continue the shaft,
which was down 200 feet, 200 feet fur
Their and crosscut to the Chicago Bos-
ton and Kill Buck veins from the 400
level. This plan was abandoned tenn
porarily on account of the large
amount of surface water but when
this subsidies the original plan will be
carried out unless some other feast
bic plan for deep development can be
found that will obviate sinking. At
the present stage of development
there is a remarkably fine showing of
ore on the Chicago Boston In the
lowest tunnel there is a big body of
ore exposed several hundred feet in
length. The shaft is a short distance
from the portal of the tunnel At a
shaft found the ore, which proved to
be of better grade than that in the
tunnel At a depth of 200 feet an
other crosscut was run to the ore.
which again showed a marked i'm
provement over that above, there be-
ing streaks running 3S per cent lead
and 81 ounces Of silver. the entire
body for 200 feet, averaging probably
10 feet in width, being good milling
ore. The steady Improvement in the
grade as depth is gained is significant
and predictions are freely made that
a great body of high grade ore will be
found when the work now planned is
accomplished.
Rich Silver Ore.
The discovery of the big Chicago
Boston lead vein a few years ago has
somewhat obscured the original gray
copper vein upon which the ground
was located and from which some
shipments were made in the early
days. Water from damaged flume
uncovered the lead vein that is now
being developed, and since that acct
dental discovery comparatively little
attention has been given to the gray
copper. With the price of silver fixed
by the government at 81 per ounce
and the strong probability that it will
again go far above that figure, this
gray copper vein with its high silver
content becomes an important factor
well deserving Of further attention.
which it will no doubt receive in the
course of the large plan of develop
ment which Mr.. Percival is prepared
to carry out
Important to Wallace People.
The development of the Chicago
Boston is a matter Of the greatest i'm
portance to the people of Wallace If
it proves to be a large productive
mine, and the indications are most IA
vorable it will mean the employment
Of several hundred men so close to
this city that most of them will make
their homes here. It will give the
business men of this city the benefit
of a large and permanent payroll pro-
mote the building of new homes and
in various ways contribute to the sta
bility and prosperity of the commun-
ity.
