SEARCHLIGHT, Dec. 14-The Pitts
burg, after brief shutdown, made neces-
sary to adjust itself to the new order of
finances, has resumed and is again direct
ing it's vertical shaft to water level.
Something over 175 feet of depth has
been gained, and while. presumably, they
are constantly making away from the
main lead, there is a remarkable persist
ency of values. The last assay from the
bottom returned s4 to the ton in gold
values. The ore body which left the shaft
at depth of twenty feet from the sur
face is now estimated to be fifty to sew
enty-five feet distant Crosscutting will
be done at water level. William Black Is
experimenting the development.
The new cyanide plant to work the big
Quartette dump will be on the 250-ton
order and should be in place by the lat
ter part of February. These tailings have
been the envy of many cyanide concerns.
but the mine officials have resisted all
offers and will attend to the reduction
themselves. They are non-committal as
to values and quantity, but consensus
of outside estimates places the bulk
weight at close to 10000 tons and a per
ton value of $3.50. Gold and silver will
probably run in the ratio of two to one.
1t is remarkably free from copper and
lead and hence is considered an ideal
proposition OF the kind.
The new 10-stamp mill from the Ris-
don iron works for the lie Roy Mining
and Milling company has arrived. The
machinery filled three cars and so far
as known everything is now here for the
new plant. Superintendent Spare is look
Ing after the construction, and, barring
unforeseen contingencies, the first grind
ing should be done early in the coming
month.
Superintendent Gracey celebrated
Thanksgiving day by starting up ten of
the twenty-five stamps at the river mill
on Techatticup ore The mine is six
miles distant and there are 400 to 500 tons
on the dump. The milling of this ore, as
heretofore stated, is largely on the ex-
perimental order. AS the ore is a sui
phide, much of the success will depend
on the values of the concentrates, which
have not yet been tested. Also the fuel
problem is important. Now wood is used.
but that is a scarce article, the supply
being almost wholly of the drift wood
variety that principally comes down the
river during high water. Hence it is
probable that the plant will need to be
altered to use oil; and in that case
better site may be secured at the mine.
suggesting the removal of some of the
stamps to that point. At the present site,
on the river bank, there is little If any
ground for tailings.
Want Custom Mill
1t is confidently hoped by other mine
| owners in that vicinity that this plant
will ultimately be available for custom
work, therefore all of the details enter
ing into the present experimental runs
are being watched with close interest.
The new shaft, styled No. /. at the For
tuna, Eldorado canyon. Is down 100 feet.
This is to go rs feet further, when a
drift will be run to tap No. Q shaft at the
200-foot level of the latter, an estimated
distance of 260 feet. If, with the COM
pletion of all this work, which will re-
quire about two months time of the new
year. the present excellent showing con-
tinues, there will be blocked out about
$500000 worth of ore. There is no doubt
that such will be the case, as the
present work is all following ore of the
$40 to $50 class and it has filed the shaft
throughout.
The next work will be to sink No. Q
shaft to water level, the depth of which
has not been estimated. The matter of a
reduction plant will not be decided on
until the character of the ore is ascer-
tanned at or below water level.
Mr.. Mcknight stated that as the For
tuna is practically a close corporation
| scarcely $4,000 of treasury stock being
out-there was no necessity of other than
the most methodical work.
c. r. Pemberton is doing the work by
contract and Mr.. Mcknight will continue
to make fortnightly trips of inspection.
This same corporation is developing
three properties in the Bullfrog section
the Mammoth, Hazel and Alta. None of
them are yet in anything like the stage
of development that the Fortuna is.
