The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1913-11-06

hard: tight, white and rusty-stained
vein quartz, with narrow. honeycomb-
ed lines. The west half Of the shoot
Is softer, more yellow-stained and por-
Gus. and largely covered with surface
debris The foot wall formation Is a
wide zone Of hard, clean, close grain
ed blush quartzite. This is succeeded
to the south on the hanging side with
blue Prichard- d-looking slate, which In
turn is succeeded to the south with
another wide zone of hard quartzitc.
carrying network of white quartz
seams and rapidly converging towards
the Hypotheek vein to the northwest.
Development.
The property has been developed
+, through an adit tunnel $50 feet long
started in the bottom of the east fork
about 200 feet to the vein, then as a
drift northwest along the vein course
| to the present shaft station, which is
at depth Of 300 feet below the high
est crest of the vein.
| This drift discloses a hard, white
banded quartz vein, with thin lines OF
copper sulphide ore but no commercial
values. The shaft is vertical and 700
feet deep. 1t has one hosting com
partment of normal size and man.
/ way 1t is equipped with a 35-foot
gallows frame and 16-horsepower
Ottumwa hoist driven by compressed
air and carrying light 1200-pound
skip
First Level.
The first level in this shaft is at
depth of 166 feet below it's collar and
Is driven 500 feet through the north
western extension of the vein, disclos-
ing a little better copper sulphide val
ues in the hard quartz near the shaft
but rapidly changing in character as
it progresses west to softer and more
vuggy quartz, chalky acid digested and
highly altered gangue and wall rocks,
with numerous short croSscuts disclos~
ing highly altered ore course 20 fsei
wide that has been almost complete
ly leached of its commercial mineral
values. but whose western limits are
yet unproven and still show a strong
face of altered mineral
Second Level.
This powerful fissure naturally war
ranted further search and the second
level, at depth of 500 feet, is still
more extensive than the first and driv
en- out under the soft west end coun'
try with increasing copper sulphide
values near the shaft and further
away, and on an apparently parallel
course. opened through a short cross
cut to the south shoot of ore show
ing an entirely changed condition
and consisting of defined ore
course, 10 to 90 feet wide and
60 feet long, that is entirely filled with
almost clean spongy brown iron and
black manganese gossen ore, threaded
with narrow parallel strlngers and
sparkling cleavage crystals Of pure
lead carbonate, on which a little stop
ing has been done and some goo1
milling ore produced. From the west
end of this ore course crosscut still
further south 60 feet has opened
parallel ore course of about the same
dimensions and filed with the same
rich looking spongy gossen ore and
leached gangue carrying little more
galena ore and less carbonate min
eral
Third Level.
The 7O0-foot level in the shaft has
been much more extensively explored
than the other two. and while some
mistakes have been made. due to local
faulting, hardly any Of it's drifts or !
crosscuts have been wasted, but can
in several instances be extended 70
excellent advantage.
This level shows increasing copper
values in the hard quartz vein portion
of the drift, where in 40-foot stope,
a lenzy band Of clean chalcopyrite ore,
4 to inches thick, is disclosed, car
rying 20 per cent copper values, with +
gold and silver values. a
crosscut south 55 feet from the hard
quartz vein opens the big soft gossen
ore shoot 10 to Is feet wide that has
been drifted on for $50 feet and Is still
showing strong vein in the west face,
SuIphidc Zone.
This handsome ore channel. while
still filled with soft, spongy black and
brown iron and manganese gossen,
presents decided increase in lead
values, including thicker bands Of
clean lead carbonate mineral, showing
swells up to 6 inches thick Of 20 per
cent lead ore, together with pseudo
morphic quartzite gangue, completely
changed to 50 per cent hard carbonate
ore. but retaining its original grain
and texture. This horizon shows
decided increase in sulphide ore that
occurs as unaltered kidneys of clean, I
fairly coarse grained galena. cncascd
with the carbonate and soft gossen.
