Mining at Breckenridge.

Breckenridge, Colo.-The Gold Dust
property in Illinois Gulch and the
West Side concentration mill are be
ing put in shape for operations by
California investors. A new set OF
crushing rolls, weighing several tons
and a new Whitley concentrating table
are being put in the mill which al
ready contains three Wiley concen-
trating tables and Whitley sinner.
The property will be operated
through the Puzzle extension shaft
temporarily while a new tunnel is be
ing driven to the vein. Heretofore the
Gold Dust has been worked through
the main tunnel of the Puzzle, with
which it is connected by a cross-cut
drift 300 feet long. The present OPP
orators offered a rental of 800 per
month for the privilege of working
through the Puzzle tunnel, which Is
about 5000 feet long, but not being
able to secure the privilege will work
through a shaft for the present and
later on will drive tunnel TO the
vein.
The mine has record of being
good shipper of heavy lead, silver,
gold ore and, it is said, there is lots
of second class ore suitable for concen-
tration in the Slopes and old workings
Of the Gold Dust. 1t will probably
take a couple of weeks to put the mill
in good order for regular operation.
The Gold Dust vein is said to be from
three to eleven feet wide, most of the
vein matter, being suitable for concen-
tration.
1t is reported a six-inch streak of
heavy galena ore has been opened in
drift from the Minnie tunnel on
Mineral Hill. The Minnie was former
ly a good producer of heavy lead sill
Yer ore and the concentration mill on
the property made good grade of con
centrates from the second-class ma
teral. The property is operated by
the Swastika Gold Mining L. Milling
Company.
The Wellington Mines Company is
putting out lots of zinc lead ore since
the wagon road has become passable
for heavy handing. Some four to six
fourhorse ore teams make three trips
daily from the mine to therailway.
Last week between thirty-five and
forty tons of heavy lead silver ore
were shipped to the Chamberlain Dill
1ingham branch sampler at Brecken-
ridge.
The Jessie Consolidated Gold Mines
Company expects to start up its forty
stamp and concentration mill in few
days, as a great deal of ore has ac
cumulated in doing recent develop
ment work. Manager James r. Hogan
expects to see the construction of a
300-ton capacity cyanide process mill
at the Jessie well under way before
autumn. The ore is of a character
well suited to cyanide treatment and
considerable increase in the profits
Of operating is expected when the new
mill is in operation.
Five churn. or oil we'll drills are
being used at present by the Colorado
Gold Dredging Company to prospect
and chart the riches of gold bearing
placer territory in both the Swan and
Blue river valleys. The two large
dredge boats now on the property have
been found to be too light and Of
smaller capacity than gold dredge
boat should be to operate to a depth
of forty feet, and SO two large, power
full modern gold dredge boats are to
be erected as soon as the material for
their construction and equipment
reaches the property. 1t is probable
that the dredges will be electrically
operated when completed. A board
ing house with twenty rooms, office
building and other buildings have al
ready been completed.
