ing done at this time ON mineral belt
extending almost in straight line
from Mullan, on the east, to the Bun
ker Hill and Sullivan mine, on the
west, and which is sometimes referred
to as the dry ore belt.
Most of the development work on
this belt is being done in a quiet way
without blare of trumpets OF news
paper publicity.
The Chicago Boston mine, among
others on this zone, is driving long
lower tunnel to tap at depth shoot
of ore which exists in its ground and
from which commercial ore has been
shipped.
Has Known Ore Body and Strong
Chance for Second One.
This company is fortunate In hav
ing not only the known quantity Of
an already developed ore body, but
also the Kilbuck vein which traverses
this ground and which has not yet
been explored at depth, This vein
will be accessible for exploration from
the lower tunnel for a distance of over
1000 feet and this vein will be cross
cut during the present summer by the
company in it's adit now being driven
by machine drills.
The history of the property is a
very interesting one because of the
character of ore outcrops and strong
veins, and the location of such a
promising mine SO near the city of
Wallace, being located on Lake gulch
adjoining the Kilbuck property which
is reputed to be owned by former
Senator William A. Clark.
Why Some Sections Arc Neglected.
1t is surprising that property
having the physical characteristics
and promising deposits of ore so
well situated for working should have
escaped the notice of the vast influx
of capital that has poured into the
Occur d'Alene district for the past ten
years. 1t has remained for the pres
ent company, however. to exploit this
property by driving the long tunnel
herein before mentioned and 1t is our
belief that on the completion of this
tunnel another big mine will be added
to the district.
The Occur d'Aenc district is a large
one and i'll it, as in most mining camps
of prominence. the prospector and the
promoter have followed devious waye
to attract capital to dig tunnels, and
perhaps it is natural for the trend Of
development to follow along particu-
lar lines, l. e. near large producing
mines, and on the continuance or the
supposed continuance of their veins.
IT is true then that we find in the
Occur d'Aenes the belt upon which
the Chicago Boston mine Is located
has been neglected in the respect Of
deep mining because until the last
three or four years most Of the cap
ital for exploring prospects has nat
urallv drifted toward and around such
mines as are producing regularly
Extending east and west and just
north of Wallace we find many of the
large producing mines and many pros
poets, while extending east and west
and just south Of Wallace is another
zone of naturalization which from its
indications will produce the mines of
the next mining generation.
Showinq and Development.
There are six tunnels and several
open cuts on the Chicago Boston pro-
perty all of which show ore in vary
ing quantities. At the time silver was
worth around 81 per ounce ore was
shipped from the No. s tunnel, and a
considerable tonnage Of ore is blocked
out in this opening which can be han
died economically from the long tun-
mel now being driven from Lake creek
Formation, Character Of Ore.
The workings Of this property are
located in uuartzite, the principal ore
bearing rock of the Occur d'Alenc dis
trict, and the outcrops of ore are sim
liar to those found in the vicinity of
!
Mullan. The presence of large guam
titles of siderite in the outcrops and
in the shallow workings would indi-
cate large ore bodies at depth. Gray
copper ore is found in abundance in
these workings and some galena. the
latter appearing more strongly in the
/ lower openings of the mine. AS the
lowest tunnel should cut the veins be-
low the oxidized zone the replacement
of the large bodies Of carbonate OF
iron Is presumably by galena, string
ers of which have already appeared n
this tunnel, and the presence Of gra,
copper almost entirely disappearing
The United States government in its
report on the Occur d'Alene ore de-
posits. issued some wears ago, touch
ed lightly on the geology of the ore
zone upon which this mine is located
and no doubt future reports from thai
source will be more exhaustive, be-
cause Of the extensive work and in
creasing Importance of this belt since
the last report was made. Many min
ing engineers for private purposes
have made exhaustive examinations
along these assures. aud so far as u
is possible to learn. are unanimous II
their conclusions that large ore bod
! les exist in them at depth.
