The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1918-01-03
templated by this company for 1918

about Is miles west of Mackay and
embraces a somewhat similar great
zone of naturalization with numerous
surface manifestations of high grade
copper oxide and carbonate ores. An
important body of per cent sulphide
ore 80 feet thick was encountered in
the development of this property dur
ing the year that is of exceptional
promise. The mine was equipped with
50-horsepower compressor and
crosscut tunnel started that has now
attained the length of 1000 feet for
the deeper development of the prop
erty.
Lead Silver Properties.
The most important mineral disclos-
ure of central Idaho during the year
was made adjoining the Empire Cop
per mine at Mackay to the west on
the Kennedy and Horseshoe properties
where a series of intrusive porphyry
and blue limestone contact sources of
closing definite evidence of a new and
extensive tonnage resource of desr-
able lead silver. ore.
| One of these properties theoretically
lease and recently optioned to the
U. S. Mining & Smelling company,
produced 10000 tons of crude ore
which was shipped to the Salt Lake

each unit of lead and marketable crude

fluXing mineral.
The Horseshoe shipments also from
leasing operations aggregated about
5000 tons with value around rs per
cent lead and Is ounces silver Half
dozen other prospects in the same
vicinity made small shipments of
similar values. The geologic condi-
tons are decidedly comparable with
some of the well known Utah deposits
of this class
Further west in Custer county along
the Salmon river the Red Bird lead
silver mine, after an idleness of 10
years, was operated by leasers and
shipped about 20 cars Of high grade
crude ore carrying 80 to SO per cent
lead and an ounce of silver to each
unit of lead.
Ramshorn Comes Back.
The old Ramshorn mine at Bayhorse
was another revival of an idle silver
ore mine which has been inactive for
Is years, and number of carloads of
gray copper ore carrying about 200
ounces of silver was shipped. This is
one of the best developed and deepest
known sources of gray copper mineral
with proven ore resource estimated
at 10000 tons u
Prospecting activity prevailed al
along this part of the upper Salmon
river and some interesting discoveries
were made including a revival of in
