THE CEDED STRIP.
Report OF the. State Mine
Inspector.

The twelfth report of John Byrne, the
state mine inspector, has been receive |
bp tn AcANTHA and in it we find the
following in regard to the mines in the
coded strip in this county:
''Tbe territory covered by this title is
a new mineral district that was added to
the others of the state a couple of years
ago through its purchase from the
indians by the government and opened
to location under the mineral act. At
the time of the opening there was a
rush of prospectors and about 100 quartz
claims were located, the majority of
which were made on two parallel fissure
veins that cut the precipitous mountains
in a northwest and southeasterly direc-
ti3n from Divide mountain to Grinnell
mountain, a distance as the crow flies OF
over ten miles. These veins are dis
tinctly marked, as they cut clearly
through every formation and leave the
vein matter visible above the shale Gov
ering the lower portions of the noun
tains. The mountains OF this district
are very precipitous, ranging from
5000 feet altitude sabove sea level TO
1850 feet.
Since the location of the claims men
toned, the majority OF them have been
placed in two groups, one with Messrs.
Holmes & C~alderhead and the other
with a company organized in this city
by the late Mr. Esler, the two covering
about all the locations made on these
assures. Messrs. Holmes & Calderhead
are running five tunnels, located at
different points best situated to develop
and demonstrate the mineral value of
about fifty claims that are under their
control, and at this writing these tunnels
are in approximately about $50 feet, but
II no instance have as yet secured per-
nanent mountain (thermaD water. The
indications are, however, that exception
ally valuable mines viii be developed
When sufficient depth is secured. On
Canyon creek, where the Esler company
arc operating, one tunnel has secured a
length Of over 400 feet and is now in a
high grade of concentrating ore, and sas
the s urface indications, formation and
vein filling is identical in all the noun
tains cut by these leads, there is little
question that the same results will be
secured with similar depth. The vein
matter is an urstratified diorite and is
all more or less mineralized and on the
surface in places shows very rich miner
alization with bornite and pyrites of
copper and carrying values of gold and
silver. In the development secured
through the district some fine ore has
been revealed and some quartz streaks
encountered i~rregularly through
the vein matter, and are composed Of
quartz spar and practically pure metal.
All of the vein matter carries iron vary
ing from 5 to 30 per cent. The leads on
which the development is in progress
will vary from Is to 40 feet in width. If
the anticipated rich deposits of copper
ore are revealed, as seems entirely prob
able, the product is likely to be reduced
in the immediate vicinity, as nature has
provided every economical facility. II
the district turns out as anticipated and
warranted 10y all surface indications and
the revelations Of the slight develop
ment SO far secured, it will materially
add to the output of the mineral wealth
of the state.
