NAME OF PROPERTY
SOAB MINE SOUTH
Relatively massive sulphides occur in Precambrian metasediments and/or
gneisses (Coats, et. al., 1972) or in serpentinized peridotite (Sabina, 1972).
Pyrrhotite, pyrite, pentlandite, and chalcopyrite are found in several
mineralized zones, which comprise the Soab deposit. A doubly plunging
fold is located near the deposit, which is reflected in the orebody being narrow
and not well defined, meandering haphazardly through the host rock (Northern
Miner, July 1, 1971).

EXPLORATION AND DEVELOPMENT
The mine is about 1 km west of Provincial Road 391 and 68 km southwest
of the city of Thompson.
An aerial magnetic survey helped pinpoint the
mineralization in 1951. Follow-up air and ground electromagnetic surveys and
subsequent diamond drilling discovered nickeliferous material. Fitz 5 (P 23362)
was staked by M. Smith in 1951 and assigned to Canadian Nickel Company Limited
later that year. This claim may not directly overlie the deposit, but a shaft
was sunk here. Fitz 5 was assigned to The International Nickel Company of Canada
in 1956 and leased as M-5348 in 1959.
Development of the Soab deposit
began 1965. Shaft sinking commenced on Fitz 5 in January 1967. The shaft was
completed to 1,984 feet by March of the next year, with levels at 200-foot
intervals between 300 and 1,700 feet (Macke). Mackenzie (1968) estimated that
the Soab deposit contains 100,000 to 1,000,000 tons of mineralized
material, including ore and protore, grading up to 1.5% Ni.
that there were 8-10 years of pre-production reserves at Soab South if
the production rate was 3 000 tons per day. The Northern Miner (Oct. 8, 1970)
stated that reserves at Soab South were "sufficient to support 3
000-ton-a-day production for 12 to 15 years." Production was expected to be
3,000 tons per day, with mining to start on the 300-, 500-, and 700-foot
In 1970 exploratory deep drilling was underway on the 1 700-foot
level. By 1971 the Soab South shaft was 2 083 feet deep. Mining was done
by the shrinkage stope method (Northern Miner, July 1, 1971).
South Mine produced from 1967 to 1971 (INCO staff, November 1975). After 1968
ore was trucked from Soab North and, together with Soab South ore,
transported by a private INCO railroad to Thompson for processing.
ceased in 1971 due to several factors leading to a decrease in "ore". The shaft
is dewatered and on standby.

In articles and reports it is often difficult to differentiate between
Soab North and Soab South. When no distinction was made the term
"Soab Deposit" was used on the front of this card.
