NAME OF PROPERTY
JEEP MINE (RICE GOLD NO. 2)
1985 - Augusta Gold Mines Ltd.
Winnipeg, MB R2C
The deposit is located within several shear zones which strike
northwest through an "L" shaped intrusion of Archean dioritic to gabbroic
country rock. Stephenson (1972) described the gabbro as slightly foliated with
some mineral alteration. The diorite, found nearer the mine is medium-grained.
Hand samples appeared to be weakly altered but thin sections showed them to be
highly altered (Ibid.).
Granitic masses intrude the diorite and underlie
about half the property. The contact strikes northwest and dips steeply to the
southwest. The granitic rocks are in turn intruded by igneous dykes of various
types. These granites separate Veins 1 and 3. Wallrock is chlorite
Mineralizaton is contained in parallel quartz veins in the shear. The
veins are narrow, never over 0.9 m in wide, irregular, and not always of ore
grade. The No. 1 vein, where the shaft was sunk, was exposed for 61 m on the
surface, but died out underground. Gold-bearing veins were found up to 183 m
from the shaft. Some sulphides and carbonates were found in the veins. Scheelite
was noted by Eakins (1949) at one place in Vein No. 1.
interpreted the host rocks as detrital sedimentary rocks that were subjected to
varying degrees of megmatization and coccmitant recrystallization. It was
proposed that the mineralization at the Jeep Mine was formed by migration
of gold from the detrital sedimentary rocks followed by deposition with quartz
in nearby fractures.

EXPLORATION AND DEVELOPMENT
The deposit is located about 6.4 km west of Wallace Lake. Several
kilometres of gravel road connect Bissett and Wallace Lake.
The early claim
history of the property was as follows:
Year Claim Name Claim Number
1934 Slip No. 11 W 4230 J.F. Barrieau
- cancelled in 1939.
Amigo No. 3 W 10736 Robert Fitzsimons
- cancelled in 1945.
1946 Rice Gold
No. 2 W 14476 W.L. Campbell
- assigned to R.J.R. Schaffer in 1946.
Gold Prospecting Syndicate explored the property in 1946.
- assigned to
Jeep Gold Mine Limited
San Antonio Gold Mines Limited formed
Jeep Gold Mines Limited to develop the 12 Rice Gold claims. Diamond
drilling was carried out on three veins.
A three-compartment shaft was
started in 1947. Surface and underground diamond drilling, crosscutting and
drifting were carried out for several years. An unsorted 291 tonnes of ore
yielded 5.6 kg (182 oz.) of gold. The milling, throughout the mine's history,
was done at the San Antonio plant. The highest assay for 1947, was 64.07g. (2.06
oz.) over a width of 0.27m and 0.25 m long. The lowest assay that year was 26.50
g/tonne (0.85 oz/ton) over a width of 0.31 m and a length of 0.71 m (Manitoba
Mines Branch c).
Two test runs of ore were milled in 1948. A total of 1099
tonnes of ore produced an average of 27.29 g/tonne (0.80 oz/ton) of gold. An
assay of 98.4 g/tonne (2.87 oz/ton) gold across 0.15 m was reported 168 m below
the surface. Recovery of the ore averaged 30.86 g/tonne (0.9 oz/ton), with a
reserve of 4990 tonnes in two veins. By June 65.16 kg (2095 oz.) of gold had
been recovered. The veins were proving variable in width, so an attempt was made
to stabilize the ore grade at 34.29 g/tonne (1 oz/ton). It was determined that
No. 1 vein did not continue with depth. The No. 3 vein became the primary source
of ore. No. 7 vein was discovered about 183 m from the shaft (Ibid.). A 21-year
lease, M-2037, was taken out in 1948.
In 1949 the shaft was lowered to 180 m.
Another two levels were added at 137 and 175 m bringing the total to four
levels. The other levels were at 38 and 61 m. The mine produced about 23 tonnes
of ore a day. Reserves from the 2 main veins totalled 3175 tonnes. Mining was
halted in 1950, though further development work was continued for a short time.
The principal ore vein did not continue with depth. The company felt Vein Nos. 3
and 7 could not support mining operations (Manitoba Mines Branch c, Jeep
Gold Mine Limited, Company Report, 1950). Some exploration work was done in 1958
The property was kept in good standing. In 1969 Transtide
Industries Limited bought The Jeep Gold Mine Limited. Later in 1969 the
lease was renewed for another 21 years. Geophysical surveys were undertaken in
1973 when the price of gold rose to $3.22/g ($100/oz). According to a newspaper
clipping, Transtide expected to do surface mining on the property (Winnipeg Free
Press, May 29, 1973).
In 1975 Rice Gold No. 2 was converted from a lease back
to claim W 14476. From June to September 1973 Transtide drilled four holes
totalling 546 m. The holes were collared east of the mine shaft and parallel to
the main shear zone. Details of the results are not available. The claim was
cancelled in 1976.
In May 1977 N. Tschunsky staked CB 8043 over the deposit
and in 1980 the property was assigned to Augusta Gold Mines Limited, a
subsidiary of Gold Lake Mines Inc. A feasibility study was completed in 1981, on
a mill designed for 180 tonnes per day (Northern Miner Nov. 12, 1981). From July
1981 to August 1982 prospecting, magnetometor and EM surveys were completed.
Gold Lake Mines 1982-83 annual report indicated intent to design a drilling
program to verify the continuity of more shallow mineralized structures to a
depth of 450 m.

1948 to December 21, 1950.

Derry Gold Mines Limited did work on property surrounding and perhaps
including the Amigo claims. They prospected veins which were up to 6.1 m wide
(Manitoba Mines Branch c, Derry Gold Mines Limited). This contrasts with the
narrow veins of the Jeep Mine.
Diamond drilling, trenching, and
pitting was done between 1935 and 1940. Assays were taken. Veins were traced for
up to 1373 m. Activity centered on the Presto claims (W 7582-85, 7634-35). It is
not certain whether any of these claims became Rice Gold No. 2. Molybdenum is
reported from the Presto group (Manitoba Mines Branch c, San Antonio Gold Mines
