NAME OF PROPERTY
1978 Hudson Bay Mining & Smelting Co. Limited
Massive and disseminated sulphides occur in at least four lenses in
graphitic rocks in Archean andesite. The graphitic rocks consist of schist, tuff
and chert. The deposit is found on the west limb of a major syncline which
plunges 10° - 20°N. The syncline, drag-folds, and the intrusion of a diorite
sill have influenced the deposit.
The lenses are at least 310 ft. long, 15
ft. wide, and 170 ft. thick. They follow the trend of the andesite which strikes
approximately N20° E and dips steeply west. The deposit rakes at
Fine-grained chalcopyrite, sphalerite, pyrite, pyrrhotite and
arsenopyrite are associated with highly graphitic rocks. They pyrrhotite is not
nickeliferous. It may form two to four barren lenses with pyrite. Galena has
been reported in the deposits. Gold and silver were extracted during

EXPLORATION AND DEVELOPMENT
The former mine was approximately 5 km southeast of Flin Flon or 20 km
east of Provincial Road 10. Three Nation (28304) were staked by J.B. Levasseur
in 1919. Some trenching was done on a chalcopyrite showing before the claim was
cancelled in 1926.
Vaughn Thompson restaked Three Nations (37357) in 1926.
More surface work may have been done before 1930. When geology J.F. Wright
visited the property in 1930 he found seven slumped, water-filled pits. He also
reported an old prospect shaft on the south end of the deposit. Channel samples
taken from the shaft prior to 1930 yielded a maximum of 3.60% Cu over 3 ft.
Wright found massive and disseminated sulphides on surface (Wright,
During 1930 Enca Exploration & Development Company, Limited
probably attempted to option the property. They encountered difficulties
assembling a large block of individually held claims. Grab samples from this
claim group assayed 1.2% Cu to 6.5% Cu. They averaged 4% Cu across 3 ft. This
Three Nations claim was cancelled in 1936.
Later that year, Three Nations (P
3065) was staked by H.L. Thompson. Diamond drilling commenced in 1938. The
program ended in 1939 after 1,701 ft. had been drilled. Tanton reported that one
hole cut ore-grade copper sulphides (Unpub1. Info. File). Early in 1939
Sherritt-Gordon Mines, Limited, Sudbury Basin Mines, Limited and Tonopah
Canadian Mines Company optioned the property (unregistered option).
Sherritt-Gordon drilled 2 415 feet in at least 12 holes. Up to 4% Cu was
reported in the second hole. Drilling averaged 2 to 3% Cu with a maximum of 15%
Zn in one intersection (Tanton, Ibid.). The option was apparently dropped in
1940 due generally to disappointing drill results (Sherritt-Gordon Corp.
In 1941 Hudson Bay Exploration and Development Co. Limited (HBED) took
an unregistered option on the property. During the winter of 1941-42 over 4 000
feet of drilling was done in at least 14 holes. By the end of 1944 the property
had been assigned to HBED, and then to a subsidiary, Cuprus Mines Limited. Over
35 000 feet of drilling located at least four ore lenses. Lease M-1683 was
issued in 1945.
The following year a three-compartment shaft was collared and
six stations were cut between 100 and 600 ft. Surface lease M-76 was issued in
In 1947, reserves were estimated at 280 000 tons grading 3.87% Cu, 7.3%
Zn, 0.049 oz. Au/ton, and 0.99 oz.Ag/ton (HBMS Annual Rept. 1947). The main
shaft advanced to 830 ft. and a second shaft was started 1 000 feet south of the
main shaft. Production commenced in 1948 when 17 574 tons of ore was hoisted
(see History of Production for yearly milled tonnages). Underground exploratory
drilling continued. January 1, 1950 reserve estimates were revised to 245 000
tons averaging 3.62% Cu, 6.8% Zn, 0.04 oz. Ag/ton, and 0.91 oz Ag/ton (HBMS,
Ann. Rept., 1949). In 1949, 79183 tons of ore was hoisted. This increased to 86
512 tons in 1951. Reserves were estimated to be 129 045 tons grading 3.35% Cu,
6.5% Zn, 0.40 oz. Au/ton, and 0.89 oz. Ag/ton at the beginning of 1952. The ore
was noted to be irregular (HBMS Annual Report 1951).
The main was deepened in
1952 to 1 052 ft. Ore hoisted totalled 85 983 tons. Reserves were revised
downward again early in 1953. The new estimate was 114 500 tons averaging 3.19%
Cu, 5.6% Zn, 0.033 oz. Au./ton, and 0.89 oz. Ag/ton at the beginning of 1952.

averaging 3.19% Cu, 5.6% Zn, 0.033 oz. Au/ton, and 0.77 oz. Ag/ton. Reserves
decreased by 14 440 tons, but 71 600 tons of additional ore was
Peak hoisting occurred in 1953 when 86 549 tons were bought up the
shaft. By January 1, 1954 reserves were down to 45 747 tons grading 2.95% Cu,
5.5% Zn, 0.033 oz. Au/ton, and 0.70 oz. Ag/ton. Reserves were depleted by 68 753
tons during mining in 1953 though 17 796 tons of additional ore was developed.
(HBMS Annual Report 1953).
The mine closed in August, 1954 due to lack of
ore. During the final stages of mining, near-surface ore was blasted and mined
from below, causing an open cut on surface (R. Glassford, personal
communication). Just over 67 000 tons of ore was hoisted during the first eight
months of 1954.
Later history is tabulated below:

Production commenced October 19, 1948 and ceased August 6, 1954 when
reserves were exhausted. Yearly figures for ore hoisted differed from ore milled
because ore was sent to and from the stockpile. The figures below give the total
ore milled and the ore milled during the first and last years of

Holloway (1939) mentions that diamond drilling has blocked out an
orebody in this vicinity. This could not be confirmed.
Cobalt bloom and
smaltite were reported on "the Rosen property", four miles east of the Mandy
Mine. This is the only know mention of cobalt in this area. Assays of up to
4% copper were also reported in the area (Copper Lode Exploration Company,
Limited, Corporation File). G. Rosen staked Rosen M.C. approximately 4.5 miles
east of Mandy and one mile northeast of Three Nations. Rosen M.C. was in good
standing from 1919 to 1976. It was controlled for a time by J.C. Parres,
Managing Director, Dee Explorations Limited. It may have covered mafic rocks
shown in this area as Unit 2, Map 807A.
