A little further south on the
opposite side of this igenous belt,
yet still within its porphyry for
nations, is located the Dickens
Custer group of assure veins
which were acquired by the
Lucky Boy Mining Company, of
Salt Lake City, of which Col.
Nick Teweek is president. This
company has equipped the prop
erty with machine drills and is
developing its extensive reserv-
es of virgin ground in very
systematic manner and was
handsomely rewarded for it's eff
forts about three months ago by
cutting a large body of rich ore
in one of the old veins which has
since kept 30-stamp mill stead
lily employed reducing the pro-
duct which yields gold and silv-
er at the rate of $75 per ton; a
little more than half of the. val
ue being gold and the balance
silver. The ore is a porphyry
quartz and containing sulphurets
of silver and free gold. The old
Custer vein is situated on very
steep porphyry mountain. 1t
has been worked to a depth of
about 800 feet below the crop
pings, above which level it pro-
duced SO, 900, 900 worth Of gold
and silver bullion at profit
of about IS, 900, ZOO. Then the
vein became lean and was aban-
doned for several years. 1t is
possible to tap this vein 3000feet
deep on its dip with an adit tun-
mel of moderate length which the
present company propose to do,
when it's great stretches of vir-
gin ground can readily be ex-
plored to excellent advantage,
and it is very likely that other
extensive bonanza ore bodies
will be found upon it.
Forming a branching arm of
this great igneous belt at a point
about 30 miles southwest of Sal
mon City and coursing northwest
there is a system of porphyry
and diorite dykes coursing
through series of vertical black
schists with q coarse crumbly
felsite granite carrying large
bodies Of oxidized ore in contact
that promises to develop into
some phenomenal copper mines.
One of these veins situated at
the head of Blackbird creek has
been crosscut at q depth of 100
feet. 1t stands nearly vertical in
the formation and is $50 feet
wide, and averages 5 per cent
copper and so cents per unit of
its copper value in gold-no sill
yer. There are two high grade
pay streaks, one on either wall,
five and eight feet thick respec-
lively, that runs Is per cent cop
per, and the balance of the body
in between is'filled with a selic-
ious schisty gangue permeated
with specks and threads of cop
per glance and native copper,
and gives average values of 3
per cent. This vein has been
opened up at short intervals
along its course for q distance of
two miles and shows the same
apparent strength throughout.
Another property on the same
creek carries five parallel veins
within 200 feet of width, cours-
ing through two of it's claims
which are laid out on the face of
a very steep mountain. One of
the middle veins has been open
ed up by 300 foot tunnel which
has gained a face depth of 800
feet, and after it gets under
ground 80 feet the point where
the oxidized surface ore changes
to high grade sulphide. 1t shows
a continuous pay streak four
inches to five feet thick that av-
erages 20 per cent copper, $40
per ton in gold and two ounces
in silver. At one of the thickest
swells in this pay streak the ore
is nearly clean copper glance
and pyrites mixed, four feet
thick and averages 30 per cent
copper and $50 gold per ton, and
it is likely when the ground is
crosscut to the other veins the
whole intervening space will
carry sufficiently high values in
gold and copper to pay for con-
centration.
To people understanding the
proverbal permanency and i'm
portance of such large deposits
of copper ore in primary forma-
ton the above may read like i'm
aginative funny tales, yet they
are absolutely susceptible to
