Centre of Ballast M.C.
Visible gold occurs in a quartz-filled shear zone in a biotite
lamprophyre dyke that intrudes Archean quartz-feldspar porphyry. Estimates of
the length of the vein vary from 46 m to over 92 m. It strikes 035°/65° SE and
averages 0.45 m in width, reaching a maximum of 0.61 m.
abundant, sometimes associated with visible gold. Arsenopyrite is prevalent in
the hanging wall and occurs irregularly on the footwall. Minor pyrite,
chalcopyrite, galena, and sphalerite are found in the white coarse-grained
quartz. Petzite, a rare, soft, steel grey gold telluride was found surrounding
gold particles (Bruce, 1917).
MINERALS OR PRODUCTS OF VALUE
EXPLORATION AND DEVELOPMENT
The deposit is located on the E shore of Wekusko Lake, a few meters
south of the south end of Herb Lake settlement. Provincial Road 392 is
approximately 11.5 km to the west, across Wekusko Lake.
In 1914 R.A.
Hazelwood and H. Vickers staked adjacent claims, Ballast (21198) and
Moosehorn (21217), respectively, over the deposit. One year later Moosehorn was
assigned to Robert Kerr. Northern Manitoba Mining and Development Company,
Limited was organized in 1915 to develop the property, though it was not
incorporated and the claims were not assigned to it until 1916. High gold values
were reported. The veins were trenched and the sinking of an inclined shaft
began on Ballast.
Early in 1917, 26 tonnes of non-handpicked ore was
shipped to Trail, B.B. It yielded $2 323.60 in gold (gold price $20/oz).
According to Alcock (1918) and the Kiskoba Mining Company, Limited Corporation
File the ore averaged $89.95/tonne or 139.89 g/tonne (4.08 oz./ton, gold price
$20/oz.). Channel samples taken from the shaft when it was 15 m deep assayed
$187/tonne or 290.79 g/tonne (8.48 oz/ton, $20/oz. gold). A mining plant was
installed. By the end of 1917 the shaft was 26 m deep. A 18 m shaft was sunk on
The Makeever brothers optioned the property in 1918. The
Ballast shaft reached its final depth of 31 m with about 15 m of drifting
done at that level. Ore sent to the Rex mill yielded 1.6 kg (52 oz.) of gold
(Robinson, 1935). Northern Canada Exploration Corporation Limited optioned the
claims in 1919-20. A 3 m shaft was completed on Moosehorn in 1919. The Makeever
and Northern Canada options were subsequently dropped. Shaft sinking, stripping,
and sampling were reported on Moosehorn in 1921. The following year a 6 m shaft
was mentioned on that claim (Manitoba Mines Branch d).
Company, Limited was formed in 1924 to consolidate Northern Manitoba Mining and
Development Limited and the Kiski Mining Company Limited. The claims were
assigned to Kiskoba that same year. Ballast and Moosehorn were leased in
1925 as L. 566 and L. 567, respectively.
Robert Kerr mined 16 tonnes of ore
in 1931. It was treated at Trail, B.C., producing 1.06 kg (34.0 oz.) of gold
(Manitoba Mines Branch a).
In 1944 the claims were optioned to Wekusko
Consolidated Limited. That company diamond drilled to 46 m but did not find an
ore shoot. The vein was calculated to average 44.57 g/tonne (1.3 oz/ton) gold
across a 0.31 m width for a length of 30.5 m. More drilling may have been done
before the option was dropped in 1945 (Manitoba Mines Branch b). The Leases were
renewed in 1947 and again in 1967.
The property was assigned to McKenzie Oil
and Gas Company Limited in 1961. Four years later, in 1965, McKenzie changed its
name to Petromines Limited. The claim was cancelled in 1971.
staked W 45289 over the deposit in 1976. Cash payments were made in lieu of work
requirements until the claim lapsed in 1981.
Peter Dunlop staked CB 13300
over the property in 1984.

authors combined the two words and called the claim “Moosehorn”. The name as
written in the official register is used in the mineral inventory.
