Leasers Duffy and Mcdonald
The motors for the Nugget mill in

to the property. The tables, classifi-
ers and other new equipment are al
installed.
Leasers are working in the U. P. R.
mine, in Central City, on a crevice
eight feet in width, all of which is
milled. While the ore is low grade, the
ease with which it is broken and the
small expense of hauling leAfes nice
profit.
A fine body of ore has been opened
in the Rockford mine. in Russell dis
trict, operated by Sherman Harris, and
shipments are being made of ore that
carries 1852 ounces of gold, % ounces
silver and Is per cent. copper, to-
tai of over 500 per ton.

the Reveille property in East Argen-
dence. A vein is now being pene-
trated by the crosscut tunnel and
small streaks of high grade gold and
silver ore are being passed.
Operations will be continued on the
Mammoth mine, East Argentine, in
definitely. Drifting is to be carried
forward from the bottom Of the ZOO
foot shaft and an eight-inch streak OF
silver-lead ore is being followed that is
worth from $45 to $50 ton.
The Scott property on Republican
mountain, Georgetown, gives promise
of soon becoming heavy shipper OF
galena ore. In the breast OF the adlt
tunnel, driven 275 feet, there is body
of solid ore seven to twelve inches
wide, running 61 per cent. lead and 50
ounces silver per ton.
l. G. MCGUIRE, leasing on the Seven
Thirty vein through the Hercules tun-
mel level, Georgetown, has shot into
six-inch streak of gray copper, assay

The Gala property in East Argen-
tine and Peru districts has been un-
dergoing development for the last
three months. The adit tunnel is in
500 feet and a body of heavy lead is
exposed eight to twelve inches wide

shipments will be started before mex.
spring owing to the bad condition OF
the roads.
The Corydon mine, located within
the city limits OF Central City and
worked under lease by home pool,
is making regular shipments, the last
two lots OF smelling ore returning 1925
gold, $50 ounces silver and $50 per
cent copper for the first class, and
$2640 gold, ounces silver and 225
per cent. copper per ton for the second
class. The mill ore is returning three
ounces gold per cord.
Arguing that the era If high-grade
ore mining is passed, and that unless
the vast lowgrade and complex depos-
its of mineral can be made to produce
profit, the mining industry must con
tinue to decline, the American Mining
Congress proposes to present bill to
the next session of Congress in Decem-
Der providing for metallurgical expert
ment stations to devise methods OF
making low-grade mining a paying
proposition.
Shipments may be started soon from
the Pride of Cripple Creek mine on
Ironclad hill by Fred Johnson. lessee,
who is doing work on the main shaft,
the workings at the north end being
closed because of the cold weather.
Here at grass roots good ore was
opened and several shipments made,
which proved the rock better than
milling grade. In the mine crosscut
will be run to the north to tap this
vein. The mine is working a full
force.
Victor c. Anderson, president of the
Colorado School of Mines at Golden,
has issued a circular in which he
states that through the cooperation of
the School Of Mines and the Colorado
Scientific Society, meetings in mining
centers of the state are to be ar
ranged for the purpose OF bringing
mining men together for mutual profit.
as well as for profit to the industry
ITSELF President Anderson offers to
provide speakers from Denver and
other places to discuss various sub
jects incident to mining, and suggests
that mining men in the different sec
tions correspond with him relative to
such proposed meetings.
A new vein has been discovered in
the Rexall mine. in the city of Victor.
1t is believed to be the Black Canon
vein, the same ore body the Gold Coin
