THE GEDDES & BERTRAND.
A Big Mine Making Its Owners 30.
naMZa Kings.

No report has recently bsen given OF
! this mine which is at present among the
chief ore producers Of the district, if, in
fact, it is not producing more than any
other mine. The mill is running smoothly
now, in perfect order, and reducing eighty
tons per day. Eight men are employed in
the mine-but one shift-and they get out
readily all the ore that the mammoth
mills can reduce. The ore body is repre-
scented as being immense as far as explored
and of unknown extent in depth and side
limits. The indications are that it is a
continuous mass from twenty feet below
the surface to the 300-foot level, the lowest
point yet reached. In this level an open
ing was made on the ore body last week,
but it has not been opened out enough to
deserve mention. The l50-foot level ia
the main level from which the ore is ex-
tracted for reduction. The chamber exca-
waited ON his level is in a breast Of ore
forty feet deep and fifty feet across. the
body of ore still extending indefinitely be-
yond these lines. Thu ore is easily broken
down, a keg of black powder bringing
down between forty and fifty tons at one
blast. The average grade Of the ore is
about $40 per ton-that is, the great mass
of it is Of this value, although there is ore
in punches in the mine which assays up
wards Of $500, and in spots rum up into
the thousands. The average assay of all
the ore reduced up to this time is approx
mately $40 per oil The dimensions Of
the ore body opened on the 150-foot level
have become 30 great that the ore is hardly
missed by the quantity removed at the
present rate of excavation in u month. 1t
is estimated that q cubic foot Of the Ged-
des & Bertrand ore weighs about as much
az the same volume Of gravel-400 pounds.
On this basis a body of ore measuring ten
feet every way would yield 200 tons; and
the fifty by forty foot chamber opened
has turned out 5000 tons. The
cost of milling and mining is not to ex-
coed SO OF Sill per ton. A perfectly safe
estimate of the net yield above all expenses
per ton on $40 ore is S25. At the present
rate of reduction, 80 tons per day. this
would bring in to the company u net
prodt of 81, 600 daily, or 5000 0 per
mouth; but say the net yield OF the ore
being reduced is only $40 per ton, this
would foot up $4s,O 900 per month. The
mine cost Messrs. GIlmer and Salisbury
S47. 900 and the mill $3.50, 600, in round
numbers, $500, 900 altogether. The bullion
shipment for September was S3I ,oOO; TINS
month it will be upwards OF 100000
What was shipped in previous months we
are not informed nor do we pretend to
give the above figures as from the books'
Our figures are only approximate and may
be somewhat above or below the mark. II
is only lately that all he machinery has
been got into perfect order and the mil
running smoothly under full Roadway
But allowing a large margin for possible
overestimates it will he seen at once tina
Messrs. Gilmer and Salisbury own a mag
~nifeent property in the Geddes a per
portance to this mining district. In les
than six months from date the mine vii
have paid all the expense of its origina
cost, as we'll as that of the splendid re
duction works, all of which, mine an'
works, will then be clear profit to the On
tsrprising prOprietors.
