MINING NOTES


Sllvcrt0n Miner.
The work on the tungsten prop
critics and the Dawn of Day on Ce-
ment creek, is being rushed as rap
idly as possible. The first mill run
of this ore was completed this week,
and the concentrates were shipped
east Tuesday morning, being shipped
to Pennsylvania for use in one of the
steel mills there. The concentrates
ran about 5 per cent tungsten acid
and this would make the value of the
concentrates about $4,000 per ton, ac-
cordlng TO recent quotations. The are
was handled in the Yukon mills which
was fitted up for this class of ore,
and the saving made was a good one.
The tungsten has specific gravity
just "A little less than lead, and it
works well ON the Whitley tables. The
Shining was slight, so that the loss
was small. While this is the first
shipment from this camp for many
years, yet the present tests have been
successful in every way, and there is
no reason to believe that this camp
should not take its place as one Of
of the largest tungsten producers in
the world. There are number of
veins in this county which carry this
metal in paying quantities, and proper
prospecting and development work
will open up some good tungsten
mines. Supplies have been taken up
and work will be carried on at the
Dawn of Day all winter.
The Silverton railway is keeping the
ROAD open to Red Mountain town and
is hauling steadily for the National
Bell mine. This property is doing
L..
the mine in shape to ship just as long
this fall as the railroad can be kept
open. They are taking In some sup
plies for the winter, aha Will keep
work going, so as to have just as large
a tonnage ready as they can when
spring opens up, and it is expected
that this property will make record
for itself next season. There is also
some other work being started in that
section, and Red Mountain should be
lively place next year, If silver
keeps up.
At the North Star, on Sultan
mountain, arrangements are being
made to resume operations there with
in "A short time. j. III. Siatery and
his associates, who bought the prop
erty at the foreclosure sale last spring
have secured the title to the property,
and are now arranging to start opera
tons there within a short time. This
is one of the most promising prop
critics in this section. In the early
days it was one of the largest pro-
ducers in this section, and produced
large quantities of high grade ore.
1t carried considerable gray copper,
and this proved difficult to mill when
they reached the lower levels where
it was necessary To mill portion
of it. For this reason the property
was forced to close down and has
remained idle for number of years.
Recently tests have been made with
the oil flotation process upon the
gray copper ores Of this section, and
the experiments prove that it will
undoubtedly solve the problem Of
handling the ores from the North
Star. If the ore mills as readily as
the preliminary experiments indicate
that it will, this property should again
become one of the largest producers
of the camp. It's working is also
great boon for Silverton. for the mine
Is located at the edge of town. and
the men can stay at their homes
in town while working at the mine
and will add greatly to the pros
perity Of the town.
