Currently the
Indian mine is held by New Indian Mines Ltd.,
through
its subsidiary, Mammoth Indian Mines Limited, which controls 66 claims in the Cascade
Creek section of the Salmon River
district.
The Indian group (original Portland No. 1 and Portland
No.
2) claims were located in 1910 to investigate surface mineralization discovered
on
Indian Ridge between Noname Lake and Indian Lake.
Initial development consisted
of surface trenching by Indian Mines Ltd. The property was reorganized in 1923 under Indian Mines Corporation, Ltd.,
which performed the bulk
of
the underground development between 1923 and December, 1925, when operations ceased. In 1946, Indian Mines (1946), Ltd.
acquired the holdings of
Indian
Mines Corporation, Ltd. and rehabilitated the camp in 1947.
The buildings were
caved by heavy snow during the 1947/48 winter and some of the buildings
were
repaired in 1948. Subsequently the Silbak Premier company made a working
agreement
with the owners and constructed a 2-mile aerial tram-line from the
Indian
mine to Premier, which was completed in 1951.
The bulk of the ore was
produced
from the Indian in 1952 and concentrated at the Premier mill. In 1953
the
operation was closed down nominally because of low lead-zinc prices. In 1962
a
geological examination of about 90 claims then controlled by New Indian Mines
Ltd.
was undertaken by a field crew directed by R. V. Best. In 1963 the company
drilled
four holes to intersect a narrow northwest-trending zone on the Missing
Link
and Payroll No. 4 claims and re-sampled eight pits and trenches.
No active exploration
has developed since that time, but access to the property which formerly
presented
severe problems have been completely overcome by the construction of the
Granduc road which passes within 2,000 feet of the main adits.
Geology
The property lies astride the
irregular contact between the border phase of the Texas Creek granodiorite and altered cataclasites derived from
conglomeratic members of the local Hazelton assemblage. In the past the local
petrology has been
poorly
understood because of poor outcrop, fairly heavy undergrowth, difficult
access,
and, most significantly, because of the use of old Premier mine rock terminology.
Both the intrusive and country rocks in which the deposit lies have
undergone metamorphism or metasomatism, as well as faulting and dyke intrusions.
Lenticular remnants of country rock in the mine area include green
volcanic conglomerate and thinly striped tuffs and siltstones, as well as their
deformed (cataclastic)
equivalents.
These country rocks have been largely altered by granitization to
produce an irregular pseudoporphyry resembling the Premier
Porphyry. These metasomatic rocks are marked by a light- to brownish-green colour, with random
coarse orthoclase and disseminated medium-grained, brown homblende
porphyroblasts.
The actual igneous contact is fairly clear in the road cuts but becomes somewhat diffuse toward the mine proper, where silicification becomes
dominant. The granitized and silicified sections are gradational eastward into the
less altered, variably schistose, light-green cataclasites of the Cascade Creek
section.
In the mine
section, evidence of replacement of metasomatic orthoclase by quartz as part
of
the ground preparation process can be readily seen. This process also involved
pyritization,
carbonatization, and K-metasomatism, which produced irregular sericitic zones
in the pseudoporphyry and cataclasites.
Subsequent to metasomatism,
steep northerly fractures developed which served as depositional sites for extensive quartz
fissure-vein deposits. These
were later cut by members of the Premier dyke swarm and again by lamprophyre dykes.
As at Big Missouri and Premier, a Bowser capping of the deformed Hazelton
assemblage can be projected on the basis of existing remnants and their structure. |
