fully 400 feet of tunnel work with
numerous deep long open cuts. Debris
covers a large portion of this zone and
cuts that have been run to determine
its course show good paintings of Gin
nibar concentrates. In fact. | am ad-
vised by Mr.. Smith that the surface
debris everywhere on the mountain
side, below the line of his lode, will
give good panning results of heavy
red cinnibar concentrates and that the
same is true of the creek bed gravels
for three miles down to the mouth of
Cinnibar creek.
Mr.. Smith also advised me that in
some high bar gravel diggings on
Sugar creek near the mouth of Cinni-
bar creek, which were worked for
placer gold and created local ex-
element a number of years ago, mug
gets Of SO per cent cinnibar mineral
were found in the clean up boxes of
the small placer operations attempted
at that date which predicates con-
siderable disintegration and erosion
of the surface since the deposits were
formed.
The tunnel work on the Smith pro-
perty at two important points. is OF
such a nature that it could be easily
turned to account with crosscuts ex-
tended at right angles through the
zone from the face of the lower tun-
mel and short tunnel under the
main bluff where the richest ores are
exhibited. These crosscuts would give
an underground cross section of the
zone at depths varying from 80 to 100
feet and would substantially demon
strate the probable permanency and
position of the richer pay ore courses.
While the continuity of this big zone
Is obscured by surface drift to large
extent the two principal showings line
up to excellent advantage in strike
and | believe the rich ore bearing po-
sition of the zone will be continuous
over a distance of more than 1900 feet
and that it presents condition oil
deep assuring and shearing of the
formation that should carry the val
ues to very considerable depth. The
zone is thought to split along it's mid
die course and the continuity of one
of it's principal branches is obscured
by deep surface debris just above
the best outcrop.

another big zone of shearing so to 70
feet wide on the Hennessy No,
claim, stands nearly vertical in
quartzite walls and strikes north 80
degrees west. 1t is richly stained
with brown iron oxide, can be traced
along the steep mountain slopes for
several thousand feet, and is said by
the owner to carry good values in
gold and to have thrown off some big
float rich in cinnibar. There was no
development on this interesting zone
OF mineral and no samples We're taken
by the writer This great lode bears
some relation in type to the Smith
zone and is worth close investigation
for cinnibar contents.
High Grade Anthony.
Below this showing, still further
down the slope of the mountain, to-
wards east fork, the Hennessy No |
claim carries a strong nearly vertical
quartz filled fissure vein in granite,
striking northeast that is 10 feet wide
and in shallow surface cut across
its course, exhibits a splendid DEM
onstraton of clean high grade anti
mony sulphide ore contents that re-
sembles in the proportion of sulphide
mineral one of the 10 to Is per cent
lead ore veins in the Occur d'Alenes.
Half a mile north of this point on
the Hennessy No. claim, a 10-foot
surface cut exhibits 4foot vein ut
contact between quartzite and
coarsely crystalline magnesium lime
stone. The vein strikes northwest and
dips northeast at about As degrees.
This shallow cross section of the vein
will average better than 30 per cent
antimony in the form of clean kidneys
of stibnite with white oXidzed sur
faces, and $50 feet northwest Of this
opening a shallower cut exhibits a
foot of 40 per cent anthony ore al
most pure stibnite in long bladed
crystals, a characteristic structure in
the several other anthony prospects
that have been located along this Dor
der of the sedimentary formations.
Several other interesting antimony
prospects were examined in this same
vicinity in which shallow cuts have
been made, disclosing in some in
stances wide zones of disseminated
anthony sulphide and oxide ore. All
these anthony bearing deposits are
believed to also carry quicksilver but
the samples tested by the writer fail
ed to yield over five pounds per ton
In the best results obtained.
am advised by Mr.. Oberbilling, one
OF the most active prospectors of the
district, that on a tributary of Cinni-
bar creek, above its junction with
Sugar creek, a mile north of Hen
