The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1923-08-23


ter officials that 1000 tons of similar
ore would be shipped to the plant
from the Yukon territory this season.
interest in the possibilities of the
north country as a heavy producer of
lead silver ores has become apparent.
especially in the Occur d'Alene dis
trict the premier producer of lead
ores in the world. The receipt of ore
in such volume and the possibility Of
even heavier shipments also means a
great deal to the operation of the
Bunker Hills big smelling plant at
Kellogg where increased activities
must result in the handling of these
ores in conjunction with the regular
run of business from the local mines
The ore was shipped by the Tread
well Yukon company, owned jointly
by the Bunker Hill and the Alaska
Treadwell f. w. Bradley of San
Francisco being president of both
companies. The mines are located in
the Mayo district, on the western
slope of the Rocky mountains. in the
southeastern part of the Yukon terri
tory, where Mr.. Bradley and Bunker
Hill associates have been interested
for several years in preliminary pros
pecting and in the development Of
properties under bond and option.
Buy Property for s459, 5000.
The property from which the ship
ments are now arriving at the smell
ter was purchased by the Bunker Hill
and Treadwell interests for a consid-
Grafton of $45S,OOO and for the past
two years has been under steady de
velopment According to reports from
the management plans have recently
been completed to drive a 25OO-foot
tunnel to cut the vein at vertical
depth of 500 feet. The No / shaft
was sunk on the dip of the main vein
for a distance of 300 feet at which
depth the 300 level was started in the
vein on ore of average grade; but the
driving of this level was stopped by
heavy flow of water that the present
pumps could not handle However
the proposed new tunnel will provide
a drainage system for this level. as
we'll as give an additional 200 feet of
depth,
The No. 2 shaft 400 feet southerly
from the No. 1 shaft, has been sunk
to a depth of 100 feet on dip of the
main vein and connecting levels have
been driven between the two shafts al
depths of so and 100 feet The 2Oo
level has been driven entirely from
No. 1 shaft and prosecuting and
raise have served to connect No .
shaft with this level.
10000 Tons Blocked Out
There are several assures crossing
the main vein and at such intersec-
lions ore bodies occur of dimensions
that have not yet been fully determin-
ed, but the underground work has so
far developed two ore bodies estimated (
to contain above the 200 level and be /
tween the two shafts, a total of 49,
600 tons of an average assay value of /
1914 ounces silver, 10 per cent lead, . I
per cent zinc and about 25 cents gold |
per ton. From the ore thus developed, /
the 1000 tons to be shipped to the /
Kellogg smelter this season has been /
selected, sorted and sacked for ship |
ment This ore contains an average /
assay value of 23O ounces silver, SO /
per cent lead, u per cent zinc and so /
cents gold per ton.
With silver at so cents per ounce |
and lead at cents per pound. this
shipping ore has a gross value of
s175 per ton. and should yield 500 per
ton over and above all freight, smelt
ing and tariff charges from Mayo to
and through the Bunker Hill smelter
TO market. The cost of developing
mining, sorting, sacking and deliver
ing ore to Mayo has been placed at
about $50 per ton, leaving a net OPP
Grating profit of $50 per ton of ship
ping; and it is estimated that about
6OOO tons additional can be selected
and sorted for shipment from the ore
remaining between No l and No.
shafts and above the 200 level. The
ore left in the mine and on the dumps
after all the shipping ore has been
removed should, according to present
information. have an average assay
value of about 47S ounces silver 10
per cent lead and 70 per cent zinc per
ton
Owns 1000 Feet on Vein.
At a point 500 feet southerly from
No shaft, sinking Of No. shaft has
been started on the main vein in ore
Of average grade; and 400 feet
southerly from No ? shaft on an adj
joining property. at point 200 feet
within such property from the houn-
dairy line, shaft is being sunk on the
