A Holman stretcher bar hoist has
been installed at the Frontenac mine
for working wines. The hoist is op-
Grated by compressed air, capacity
$50 pounds with vertical lift of 200 IT.
1t has double cylinders 3x5.
Manager Adams of the National
tunnel shipped so tons of crude ore
to the Iron City mill, receiving IL Cons
of concentrates that sold for $120
per ton net, assaying $50 ounces of
gold, and $50 ounces silver per ton.
From run of 13 cords of dirt
made at the Buell. mill from the Rock
ford mine on Quartz hill operated by
Sherman Harris, retort was depos-
tied with the Rocky Mountain bank
today, weighing 3S ounces. The ore
made heavy concentrates Of good
value.
James Moody and Michael Klais
have opened up fine body of ore in
the Bonanza shaft of the Mabel tun-
mel in lower Russell gulch. At
depth OF 80 feet they have two feet
of ore that averages .S2 ounces gold,
silver 8 ounces to the ton. A new
whip has been installed to replace the
old Armstrong hoist.
Messrs. Tibbets, Oliver and COM
pany, formerly operating on the War
Dance. have taken lease on the Sill
yer Dollar mine in Russell. They will
sink the present shaft to further
depth Of 100 feet and crosscut on the
| $50 level to reach the vein where
there is known to be eight ounce
gold ore. The installation of an ell
ectric hoist and compressor Is one
OF the contemplated improvements for
the more economical working of the
property.
Leopold Sternberger was in town
yesterday and today, attending to
his Gilpin county interests. On the
Cherub, a new location, he has
shaft down 80 feet with Az foot
showing of ore, some Of which az
says 400 ounces IN silver with one
hah ounce gold and 40 per cent lead.
Traces of Platinum are in evidence.
A commodious shaft house has been
erected and connection made with
the power plant on Fall river. A
So h. p. electric hoist has been in,
stalled. The shaft is double compart-
! ment, 6 feet by 10, built with the
idea of sinking to a great depth
| Ground was broken today for the
new shaft house on the Pozo mine.
Al rs h. p. electric hoist will be install
mess. The shaft will be sunk to the
led as soon as the building is in read
Newhouse level. The shaft Is now
down 265 feet, showing a vein from 4
to feet in width, of profitable ore.
1t will take some 1900 feet of sinking
to meet the workings in the tunnel
which are outputting about ten tram
ars per day of ore havinsc an average
value of $4,000 per ton. The manage
ment figures that it will be more pro-
fitable to work the mine by the shaft
than by raising.
| A local pool operating the trouble
some mine on Winnebago hill is
meeting with great success in devol-
opment. From the winze in the 160-
foot level. which is SO feet deep. a
shipment was made last week that re
turned as follows: Ten tons Of the
first class netted $34.40 per ton, sec
ond class 7h tons, $3.50 per ton.
Seven cords of mill ore plated two
ounces gold to the cord with a car
load Of concentrates worth $14.00 per
ton net. A prior shipment OF eight
tons first class returned $31.90 per
ton. second class, 12 tons. $11.22 per
ton net. Mill ore, seven cords, "a
ounces gold on plates with concen-
trates which sold for $11.00 per ton.
The mill ore is handled by the Polar
Star mill in Black Hawk. With the
Improvement in values over previous
shipments the operators are elated
and justly believe they have one Of
the coming bonanza producers OF the
county.
