WHITE CAPS IS
ROASTING ROCK
NEW TREATMENT PLANT is IN
OPERATION AT MAN
HAITIAN

Aside from the fact that the re-
ports from the White Caps mine for
the past week are in all respects
highly satisfactory, the most inter-
esting special feature of the infor-
nation given put has reference to
the new roasting plant. AS has been
reported heretofore, the combustion
chambers through which the heat
was introduced to the rooster proved
troublesome because of defective
brick. which melted under the high
temperature necessary to properly
roast the ore preparatory to cyanida-
ton.
The management experimental
with different character of fire brick
and went through the unfortunate
experience that has proved quite
common among users of fire Drlck,
all of whom have learned that near
" all fire brick recently manufac-
tured is of a very inferior quality as
compared with the brick
tured in the past, the reason Tor the
poorer grade being the pressure I'M
posed on manufacturers In conse-
duence of war conditions.
The White Caps company, after
considerable experimentation, hnal-
ly decided to abandon the brick COM
bustion chambers and to introduce
the oil blast directly into the bot
tom over the furnace, n the re-
suits have proven successful far be-
yond the expectation of the manage
ment.
The furnace is now working with
absolute perfection, maintaining It's
heat with practically no variation
and entirely removing the only diff
Guilty of any Importance encountered
in starting the operation of the new
mill.
During the time the mill was re-
Gently closed down to make the re-
pairs indicated, the management
took advantage of the opportunity
to enlarge the ore openings In the
furnace ovens in order to increase
the daily tonnage capacity, and the
result in this respect is entirely sue
cessful.
The mill even yet is not running
to it's maximum capapity, but 1T is
expected that before the end OF the
coming week touching up all details
of mechanical construction Incl
dental to starting of any new mill
will have been so completed that the
whole plant will be in full and con-
tinuous operation, maintaining a
daily average of at least 175 tons.
Work was somewhat retarded in
the 55O-foot cross-cut, about which
SO much has been written frequently.
The management expresses some dis
appointment at not having reached
the ore-ody on this level before now,
inasmuch as it has been confidently
expected that it would be opened be-
fore this. Work has been retarded,
however, because of numerous un-
toward and ~unfavorable conditions.
Not the least of these has been the
difficulty in securing expert miners
for this character of work.
Under normal conditions this
cross-cut should have progressed at
least 10 feet per day, and the record
of advance for the last month hardly
exceeds half this footage.
The cross-cut, however, passed
through the lime fault some time
ago at almost the exact point where
it should have been encountered,
and the management reports that
only Is feet more work will be nee
essary to reach the point where the
ore should be encountered as project
ed CT the maps. Thus, by the mid
die Of the week, even at the present
rate of retarded progress, thesensa-
tional event of the cutting of the
downward extension Of the big east
ore-body will have come to pass.
The ore from the mill is coming
from the third level east ore-body.
An average of 100 cars of ore is
hoisted during each days work,
which totals about 100 o n of ore
into the mill after some sorting of
lime has taken place. In the mill
every feature of the various pro-
cesses is working like clock-work.
The rooster is causing no further
trouble since the hearths were re-
bricked with a special fire brick.
A supply of Case oil burners has
been purchased and will be tried out
in the rooster with the expectation
that they will give good satisfac-
ton, as they are practically auto
matte in observation-disclosures Miner.
