was tenacious and chung to the task
until today he has one of the great
est silver-lead mines ever opened in
any country. with the ore developed
to a depth of 400 feet and showing
"a width of 140 feet between walls
on that level. The zinc content is
growing less with depth and the
lead and silver values increasing,
much of the ore now being devel-
oped being "a typical steel galena
and carrying excellent values in sill
yer.
The property is developed with
levels at 80, 80, 1870, 230, 800 and
400 feet. Ore has been disclosed
at surface for "a length of about
1900 feet along the lime and rhyo-
lite contact. Down to the 230-foot
level the ore was largely of a car
Donate character, but turned into
sulphides at that depth. When
crosscut at the 3O0-foot level the
ore was shown to be n feet in
with, and this increased to 140 feet
wide on the 400 level. What di-
mansions it will assume with addi-
tional depth is interesting to on
lecture until demonstrated by devel-
opment.
p The average mine values are
about $24 per ton in lead, silver
and zinc, the lead carrying the sill
yer. The complex character of the
ore requires concentration and sep
aration of the lead and zinc to
make both of these contents a prof
liable shipping product, but extens-
i've experiments by various metal
lurgists have been and are still in
progress for determining the best
method, and a successful outcome
seems assured beyond a doubt.
At the present time experimental
work is being conducted at the
mine with a small Janney oil flota-
ton plant, and a mill of 10 to 25
tons daily capacity will probably
soon be installed for larger expert
ments on development work alone.
The underground development is
being conducted along large and
comprehensive lines under the di-
rection of E. w. King. A series of
faults at times present some inter-
esting geological studies, but they
are being carefully mapped and cor
related so that their problems are
now becoming quite clearly under
stood. In addition to prosecuting
and other prospecting work on the
400 level, approximately $50 feet of
drifting has been done on this level,
there being a large body of nearly
solid steel galena carrying good sill
yer svalues contiguous to the face
of the west drift.
The shaft is vertical to the 800
foot level, and from there follows
the lime footwall on an incline
varying from 60 to 70 degrees. This
shaft will be sunk further for de-
velopment purposes, but a new YER
tical three-compartment working
shaft is geing planned, its exact To-
cation to depend upon ore disclos-
ures with further development from
the incline shaft.
The original hosting and Othe:
operating equipment has been grad
ually added to as requirements in
creased, but a powerful new plant
is now being installed for unifying
all power and charging operations.
This will include a 700-cubic foot
Sullivan compound compressor. with
la 100 horsepower Western duplex
engine to drive it; a 100 horse
power Fairbanks-Morse engine for
driving a IS horsepower generator
and a smaller generator; a so
horsepower Fairbanks-Morse hoist
with 1000 feet of cable, and a No. Z
sinking pump. Six machine drills
will be handled with the new equip
ment.
With the Simon Silver-Lead mine
as the center-piece, numerous other
companies have been incorporated
and are pushing operations in what
is now commonly known as the ST.
mon district, it being formerly
called the Bell district, and many of
them have excellent prospects for
soon developing into notable pro-
ducers of silver and lead or silver
and copper ores, from veins within
the lime and associated formations;
and in addition to this there is an
extensive belt of porphyry in which
very important gold values are be-
ing developed.
