rite. The Crystailte vein strikes north
IS degrees west. Its maximum width
is about eight inches, but the ore is Of
higher grade than that OF the Nabob
fissure and consists of fine grained
galena and sphalerite. ore on the
dump, said to have been obtained from
the V vein, shows galena. sphalerite
pyrite, and chalcopyrite in a quartz
and siderite gangue.
Liberal King.
The Liberal King property lies near
the northeast corner of section 20, T..
As N. r. 2 E., on a steep hillside slop-
| ing to Pine creek. Two tunnels sew
eral hundred feet apart have been
driven here, but the principal develop
ments are in the upper tunnel, which is
at an altitude of 1850 feet, Is driven
eastward 500 feet, and tntersects the
vein short distance from the portal
and then follows the north wall to the
face. Several crosscuts were driven
across the vein at intervals of about
100 feet. The vein trends north rs
degrees west and is mostly vertical,
but in some places 1t dips steeply north
and in other steeply south. The vein
is a fissure Filling seven feet wide with
generally we'll defined walls, but in
places numerous quartz veinlets lead
into the slate wall rocks. Near the
portal of the upper tunnel the vein is
stained with copper carbonates and
there is considerable chalcocite. The
ore minerals are pyrite. sphalerite,
Ichalcopyrite, and galena in quartz
gangue. In places the quartz for
width of several feet is almost free
from sulphides. Siderite was not OBJ
served in the vein. The copper, zinc,
and lead content of the vein was not
determined, but an assay for gold and
silver gave OCT ounce Of silver and
| COS ounce of gold to the ton, Chal-
copyrite is the most abundant ore
mineral of the vein, closely followed
| by sphalerite. Galena occurs as thin
films in the fine grained sphalerite
and is evidently the later Of the two,
but the order of deposition of the
other minerals of the vein is not APP
parent in the specimens collected.
v and Idaho.
THE adjoining V and Idaho claims
are located on veins $50 feet apart as
exposed in the bottom Of the gulch
that drains southwark past the portal
Of the Nabob tunnel These veins are
explored by old workings in the gulch
bottom.
The V vein is prospected by shall
low shaft and a short tunnel driven to
the east The vein strikes north 80
degrees west and apparently is YER
teal The Idaho vein is developed by
a drift 200 feet long from short
Crcsscut tunnel. 1t strikes north 90
degrees west and is vertical. Each
vein is about two feet wide.
The veins are essentially fissure fill
ings, though in places fragments of
the sheared slate wall rocks are in
cluded in them and are partly replaced
by ore The ore differs from that of
the Nabob vein in the abundance of
chalcopyrite and quartz and in the
absence of pyrrhotite. Sphalerite, ga :
lena. and pyrite occur less aboundant
ly than chalcopyrite. The ore is part
" oxidized in these workings, as shown
by malachite stains and thin films OF
lsCoty chalcocite ON chalcopyrite. The
minerals are intimately associated and
give little clue to their order of de-
position
