MORNING MINE HAS
ENORMOUSO ORE BODY
Proved to Be 800
Feet Long on
1000 Level
IS OVER 35 FEET WIDE
Decided Improvement in
Grade of Ore--Adopt Novel
Mining Method

TINE BEST ore and the larges
body that has been found in tn,
Morning mine in many years j.
now being mined on the 200(
level, according to a statement by
Frederick Burbidge general manager
of the Federal Mining e Smelling
company. the first of the week. The
improvement in the grade of ore is
due to the pronounced decrease in the
amount of zinc and a corresponding
increase in silver ore, features of
the great vein on this level being
streaks of practically clean galena
varying from a few inches to a few
feet in width interspersing masses of
lower grade ore. This great ore body
has been drifted upon both east and
west of the shaft a total distance of
500 feet and there is no evidence in
either face of a decrease in the
amount or quality of the ore. The ore
in places is 35 feet wide and has never
varied more than a few feet from that
width. 1t is a wonderful showing of
ore taking rank among the largest
bodies ever developed in this district
and indicating further increase in size
and improvement in grade with addi-
tional depth. The shaft is now being
sunk under contract 200 feet further
and the vein on the new level will
probably be crosscut in about 60 days.
To say that this great ore body is on
the 1000 level is misleading to those
not familiar with elevations at the
Morning The 1000 level is 1000 feet
below No. tunnel level The main
working tunnel of the Morning, which
outsiders generally refer to as No. g. /
is 500 feet below No. 5 and by the /
company it is called the 500 level /
Thus the so-called 1000 level is only !
1900 feet below the 800 or No. tunnel, |
the main outlet to the mine It's total /
depth from the surface is about 5000 .
feet.
Novel Mining Method.
The Morning has always presented .
a difficult and expensive problem in
mining on account of the ground
movement which exerts a tremendous
bers. The shaft requires continuous
attention to keep it in perfect Operat-
ing condition, while the drifts on the
various shaft levels have been even a
more difficult problem to keep in safe
and serviceable shape. After many
years of study and experience in deal
ing with the ground movement prob
~, boc
devised which it is believed will safe
guard the drifts on the various levels
and at the same time make a substan-
tial reduction in the amount of tim
Der consumed. This plan is being
tried out for the first time on the 1000 ]
level and has proved a success. Brief
ly stated, instead of opening up the 1
level by drifting on the vein and thus
exposing it the ground movement or
pressure that will manifest itself as
the slopes are opened. the drift is run Z
in the country rock parallel to and s
well removed from the vein. From i
this drift raises are made to the vein,
entering it at an elevation of about }
three floors or 30 feet from the bot S
tons the slopes are carried up in the
usual manner, leaving the vein below
The next level below
will be worked in the same manner, ,
the slopes being carried up to mine
the 30 feet of ore that was left in the
bottom of the level above With the
ore all removed and the slopes more
or less filled with waste, the ground
pressure is no longer a matter of seri-
Gus concern.
Full Working Force. +
The Morning is now employing ap- Il
500 men and the labor a
problem seems to have been effectually ]
solved The difference in pay between =
machine men and muckers has helped C
to relieve the shortage of the former :
who preferred to muck so long as the G.
machine man received no additional s
pay Now that the machine man is "
paid more. men do not hesitate to =
take the job which requires skill, ex- 8
perience and also involves response Il
