CAPS IN
BIG OREBOD|ES
CHANGES ARE BEING MADE IN
COMPANY'S REDUCTION
PLANT

ACTIVITIES Oh the greatest ihPOi
ance have been in progress recently
at the White Caps mine at Manhat-
tan. Since the last report was given
out the drift on the 550-foot level
has made about 10 feet additional
distance on the strike of the ore
body, and the management is highly
elated over the fact that the average
value of the ore shows constant in
crease in value.
This drift has now been advanced
over 80 feet in the %orebody, and the
assay across a width of about seven
feet returns values of over $35 per
ton. 1t will be remembered thai at
the point where the ore was first en-
countered the values ran slightly in
excess of $24 per ton, and 1T is a re-
markable demonstration of the per-
sistency and uniformity of this SEN
sational ore deposit to know that as
progress has been made in the ore
body the values have gradually i'm
proved, increasing with each round
of holes until now the remarkable
average of over $35 per ton repre-
sents the grade of ore after 80 feet
of drifting.
1t is impossible to correctly esti-
mate the width of this enormous
mass of ore. as M cross-cut has yet
been started to the hanging wall OF
the shoot. This will be started very
shortly, however, and it will surprise
no one familiar with general condi-
tions surrounding the big east ore
body to have it finally demonstrated
that it's width and length on the $50
foot level will far surpass it's dimen-
sions on the 435-foot level above,
where, as has been frequently stated,
the ore-body is 1915 feet long, over
35 feet in width, and maintains an
average value of about $36 per ton.
Preparations have been practically
completed for starting the ~cross-cut
on the 550-foot level to encounter
the downward extension of the shaft
and west ore shoots, which have
been opened up extensively on the
435-foot level. Because of the rake
of the ore shoots and the dip of the
formation the west crosscut on the
55O-foot level must be advanced con-
siderably further than was the case
in connection with the crosscut on
the other side, but with the excel
lent mechanical facilities at the
White Caps mine 1t is expected that
tho West and Shaft orebodies will be
encountered on the fifth level with
in a very short time.
The raise in the h~igh-grade ore
from the fourth level in the east
orebody, which holed through last
week into the third level above, has
been completely finished sc that
stopping operations in the high grade
ore may continue without Interrupt
ton hereafter, thus enabling the
management to secure such quantity
of high grade as may be necessary
10 sweeten the product from the up
per levels and maintain the regular
value of the ore over $40 per ton
for the mill, even though the ore in
upper levels run considerably lower
in consequence of the extraction of
the high grade ore by leasing oper-
ations in the past.
Manager Kirchen has decided to
install several minor improvements
in the mill. with the view to greater
economy of operation, increased gen
eral efficiency, as we'll as adding to
the daily tonnage capacity OF the
mill and an important increase in
the extraction Of the values from the
ore.
In the first place a new system for
conveying the ore from the rooster
to the cyanide tanks will be in
stalled, which will result in a ma
terial saving of labor, together with
other advantages that always accom-
pany automatic handling of ores in
process of reduction.
Another very important improve
ment in the mill will be made in sep
arating the shines from the sands
by a Dorr classifier which is now on
the ground. The shines represent
