abundant in the lower tunnel, with
an occasional crystal of sphalerite
but sphalerite was not noted in the
ore shoot of the upper workings. \
sample across a 4-foot quartz lens in
the lower tunnel is reported to have
yielded IS 70 the ton in gold. In both
the middle and upper tunnels the ore
the strike of the vein. The ore, which
has an average width of 3 feet, is con
tn ined in fault zone whose walls are
from to 5 feet wide. Stibnite re-
places both the slate and the vein
quartz; a rich streak of crystalline
though sheared stibnite, from | inch
to % inches wide, occupies the center
OF the ore. and the poorer grade ore
consists of disseminated stibnite in
the slate. The high grade shipping
ore assays 55 per cent of anthony,
Some of the lower grade material
was concentrated by hand jigging to
a shipping product, but there is said
to be 200 tons of ore containing 90
per cent Of anthony on the dumps.
! Pearson.
/ The Pearson prospect is in section
"a, T. As n, r. l E. in a small gulch
tributary to Ross fork. The property
was not being worked at the time of
examination. About so tons Of anti
mony ore said to have been shipped
in 1916. The openings consist of a
short crosscut tunnel and drifts on
the vein attaining a length of $50
feet and a maximum depth of so feet.
The vein is contained in a we'll de-
fined shear zone several feet wide,
(which trends n, 40 degrees E. and is
vertical. Thin bedded blue and green
states are the country rocks. The
vein has been stopped to the surface
through a distance of 100 feet on the
strike. The ore appears to be large
ly a result of the replacement of the
sheared states by stihnite. Quartz
was not observed but calcite crystals
occur in vugs in the ore.
Hannibal.
! The Hannibal group of three claims
was located in 1914. 1t is about 1890
feet south of the Pearson prospect
The development work comprises a
crosscut of 100 feet and a drift on the
vein Of $50 feet. The vein trends N
10 degrees E. and pdis 60 degrees w
It occupies shear zone with walls
three feet apart in states and a shear
ed greenish rock that is evidently ar
altered dixie rock on the belt which
extends between Ross fork and the
Tlberius prospect. Stibnite occurs il
the shear zone in punches and lenses
in places inches thick, but no ore
body of commercial size has been de-
veloped Several tons of high grade
ore is in the bins, bnt no shipments
have been made from the property.
A few hundred feet west of the an
timony vein an inclined shaft ha
been sunk go feet in a shear zone
feet wide that trends n As degree
w. and dips 60 degrees SW TIL
sheared rock is sparsely mineralize'
with galena and sphalerite.
sIDERITE VEINS.
Veins composed principally of sid
erite occur in the southern part o
the drainage basin of the West For
OF Pine creek. They are contained i
fault assures in Burke, Revett, an
St Regis rocks, but there is no grea
displacement of the strata.
Palisade.
The Palisade Mining company own
16 claims In sections 8, 9, 16 and Il
T. AZ N, r. E., on the southeastern
slope of Twin Crags. Development
Iwork was begun here in 1870 and
represented principally by a tunnt
500 feet long on course N 65 de
grees W., driven to intersect sewers
veins that crop out on the slop
above the tunnel. A barometric read
ing at the tunnel gave an altitude @
4140 feet Green shales and quartzit
: interbedded with brown and purpl
ouartzites of the st. Regis formatio
are cut by the tunnel. They strike \
IS to 70 degrees e. and dip uniforml
25 degrees S. The quartzitic bed
contain abundantly disseminated sid
erite. Several dark bikes from !
20 feet wide which strike about J
80 degrees w. adst vanteird cmfWy
30 degrees W. and stand vertical Wer
noted in the tunnel section Tines
i bikes are described on page 8. Nor
OF the veins have been intersected
: the tunnel, but several crop out

I fragments from them are found near
0 to the summit of Twin Crags. Tf
I veins are 5 feet wide in places, bl
