The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1918-03-21


Mace mines of the Federal company,
covering one Of the most famous single
ore channels in the entire district, Is
exhausted of its present known ore
resources. and its extensive UNDER
ground improvements are being dis
mantled at this time below the drain
age level This deposit has, apparent
lily, answered the forecast of FREDERICK
Leslie Ransome of the United States
geological survey in professional
PAPER No. 81, as to it's probable max
imum range in depth below the drain
age level of the country, and has
greatly enhanced the value of that au-
thority's remarkable deductions In this
respect.
This great ore body came in at the
surface with short finger pointed out
crops high up on the canyon side, that
rapidly expand to a palm or tabular
ore shoot in the vertical assures in
which it occurred with a length Of
over 1000 feet 1t was cut at 1900 feet
deep by the Campbell tunnel at the
drainage level of Canyon creek. and
from that point developed through
vertical shaft 1900 feet deep. 1t had
a pitch in the plane of the vein OF 40
degrees through and into three diff
ferent claims, the Standard, Mammoth
and Greenhill- Cleveland. 1t extended
In it's longest axis in the pitch of the
shoot from the surface to the lowest
productive point for depth of over
1000 feet. 1t produced one Of the
cleanest lead silver ores in the district,
averaging around 10 per cent lead and
10 ounces silver per ton, and showed
little increase in zinc contents in it's
lower horizons, but maintained it's high
proportion of silver values to the bot
tom limit reached, and made gross
pi oduction estimated at between fifty
and sixty million dollars worth OF ore
It's profitable resources rapidly con-
tracted below the 1S00-foot level in the
shaft and terminated In sharp point
ed root only a few feet in length In
a winZe below the 1900 foot level. This
remarkable ore body has been one of
the most profitable producers of the
district for the past 80 years and prov
ed virgin channel of mineral UNI
touched by erosion, and would prob
ably fit as an average in the type of
vertical tabular lead silver deposits of
the district in persistency, as out
lined by the government report re-
ferred to.
A recent published court proceeding
affecting the Hercules mine referred to
a shortening of it's famous main ore
body below it's drainage tunnel level
at 2400 feet deep under the apex of
the vein, which may, however, prove
to be a bend in the direction Of the
main shoot. This mine has been
most vigorously operated since its
main bonanza ore channel was first
has maintained a heavy
ore, without special regard to advanc
ed reserves. 1t was the most actively
developed of the big mines of the dis
trict during the year, and its deeper
horizons may yet afford some interest
ing surprises in new and ultimate total
ore resources
At the Hecla mine the existence Of
al associated igneous dixie with the
main ore body and its influence in
the ore to a great depth is
of considerable promise that
will probably be in a measure mater
tally demonstrated during the coming
year by the extension of new level
at the 2000-foot horizon of the main
shaft, to which point it has been ex-
tended from the 16O0-foot level during
the past year.
The 1600-foot level of this mine ex-
hibits better and richer ore resources
al this time than any level in it's his
tory, and add to this its other ore re-
sources above the drainage level. this
property has exceptional future prom
Use, which has been brought out by the
warranted push of the man
agement during the past few years in
extensive crosscutting development
work that has produced marked re-
suits in added ore resources to what
was supposed for number of years
to be one straight channel.
This is development policy that
could doubtless be very profitably fol-
lowed by operators at several of the
other vertical ore channel mines of
the district
The Morning mine continues to
r,anfest the maximum ore resources
os its history and is as strong and
lorg in its bottom level, over 5000
feet deep vertically, as it has been at
any point.
AT the Bunker Hill & Sullivan the
No. IA, or S4OO-foot level, in the dip
Of the vein continues to manifest the
richest and cleanest ore condition in
the history of the property. and the
&c illogical conditions at that deep hor-
lion gives no reason for present con-
Germ in regard to its further extension
IN depth
The Last Chance mine at Wardner
Is a part of the general line of ore
development of the great Wardner
ode. 1t has been exhausted to its
