The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1920-01-01

cal veins Of the Occur dAlene dis
trict in regard to its geologic and
mineral characteristics than anything
else in the state. 1t is developed 500
feet deep through adit tunnels, has a
handsome ore reserve and an exten-
siv stretch of untouched virgin vein
groupings. A light shay railway for
which the present wagon road grade
is adapted on a maximum grade OF 4
per cent, would solve the transporta-
ton difficulties of this interesting de-
posit.
Second in Copper.
Among the copper producers Of the
state Mr.. Bell gives the Richmond. in
the Coeur d'Alenes, second place dur
ing the year, having shipped number
OF cars of crude ore ranging from to
10 per cent copper The Empire Cop
per company, operating by lease sys-
TEN at Mackay, in Custer county, Is
credited with the states heaviest
yield in red metal, maintaining an av-
erage Of 1900 tons per month carrying
4 to per cent copper This property
employs an average of 100 men. A
new development tunnel has been
driven 5000 feet for the exploration of
the big ore zone in this property at a
further depth of 900 feet below the
present producing levels and new ma
chinery and equipment has lately been
installed to handle the increased out
put which will be available from this
level.
New Copper Finds.
A new copper discovery that bids
fair to assume large proportions dur
ing the next year, was made in Wash :
ington county, within 10 miles of rail
transportation. The find was made on
Cuddy mountain and is being explored
by the Idaho Copper company. The
deposit consists Of a zone of altered
monzonite 400 feet wide with flat
dip to the east near the summit of a
big mountain unit Of this eruptive
granetic rock. A tunnel 750 feet in
length secured face depth of 600 feet
and disclosed $50 feet Of soft chalco-
pyrite ore, being well disseminated In
the hard gangue and averaging l pei
cent copper with so cents in silver per
ten. Extensive developments will be
carried out on this deposit during the
year and methods of treatment work
ed out which should result in heavy
: shipments.
