DESCRIPTION OF
DEPOSIT
The surface rocks immediately around the shaft are pyroxene and
magnetite gabbros of Archean age. These are indicated as the Diana intrusive by
Russell (1950). Pillow basalts of the Rice Lake Group, Gem Lake Subgroup,
outcrop to the north and south.
Quartz lenses occur in masses up to 60 m
length, and are mineralized with arsenopyrite, pyrite, galena, chalcopyrite and
free gold (Manitoba Mines Branch b). These were exposed by stripping and
trenching on Bon No. 1 and No. 2. There were four vein systems exposed at
surface, three of which are now covered by tailings. The veins strike
295°/70-75°NE and occur in a highly schistose zone in greenish grey basic flows
(Wright, 1932). Titaniferous magnetite and leucoxene are abundant.
The ore
shoots are composed of tourmaline-bearing white quartz which carries native gold
(Russell, 1950). These veins are of three different generations, the first a
dark quartz, the second vitreous white, and the last quartz which probably
brought in the gold.
There are four or five quartz vein systems which contain
gold. The most productive vein system was No. 2 vein. Gold was mined on the 38 m
level producing 8702 tonnes of high grade ore. A total of 4500 tonnes of lower
grade ore was mined from the vein system on the 76, 114 and 190 m levels. At the
230 m level, 2519 tonnes of ore was taken from the No. 1 vein.
Vein No. 1 was
exposed 12 m east of the shaft. The No. 3 and 4 veins are 18 and 26 m north of
the shaft respectively, but are no longer exposed. Vein No. 2 is exposed for a
length of 37 m and maximum width of 6 m.

HISTORY OF
EXPLORATION AND DEVELOPMENT
The mine shaft is located 305 m northwest of the west end of Kickley
Lake. The nearest access road is Provincial Road No. 304 which is 19 km
northwest of Bidou Lake.
The area was staked as Bon No. 1 (40215) by David A.
Foster and optioned to W. S. Kickley in 1926. Between 1926 and 1927
approximately 50 claims were staked around the main showing of gold. Work on the
property uncovered quartz veinlets that for a length of 34 m and an average
width of 2.4 m averaged approximately $9.04 tonne gold (Wright, 1932). These
claims were surveyed in 1928. Gem Lake Gold Mining Company Limited was formed to
take over this property in 1926. This company merged with Boundary Mines Ltd. in
1928 and formed Gem Lake Mines Limited. By 1932 a 45 tonne mill was installed at
the mine. A three-compartment shaft had been sunk to 236 m with levels at 38,
76, 114, 153, 190 and 229 m. Approximately 3050 m of crosscutting and drifting
and other underground work was completed. Total production from 1928 to 1932 was
16.95 kg (545 oz.) gold and 1.24 kg (40 oz.) silver. Gem Lake Mines Limited was
liquidated in 1932 and Diana Gold Mines was formed the next year to take over
the holdings. Assays on the ore were as

During 1934-1936 the mine operated at 36 tonnes per day with an
average head grade of 19.59 g/tonne (0.57 oz/ton) gold.
Diamond drilling was
done in the mine from 1935 to 1936 with a total of 1524 m in 23 holes drilled on
all six levels and the surface. Traces of gold were found in all holes.

In 1936 Diana Gold Mines Limited was liquidated and the
property taken over by Consolidated Diana Gold Mines Limited. The claim group
(Bon, Brittannia, Gold Strike, etc.) was leased the next year. A four hole drill
program was undertaken to test the vein at a depth of 305 m (Manitoba Mines
Branch b). Surface exploration continued on the property and a quartz occurrence
containing gold was found 153 m from the shaft.
The mine became inactive in
1938. This company produced 15.83 kg (509 oz.) gold over a one year
period.
In surface clean-up operations during 1940-41, 3.02 kg (97 oz.)
gold and 0.31 kg (10 oz.) silver were recovered. The total production for the
mine was 235.57 kg (7574 oz.) gold and on uncertain amount of silver. The claims
involved in the Diana Mine were Bon No. 1 which contains the shaft, underground
workings and tailings, Bon No. 2 which had some of the underground workings and
tailings and Bon No. 3, 4 Frac. on which the tailings were dumped.
The claim
group was cancelled in 1959. The history after this is as follows: Note: in 0 is

In 1959 six pits totalling 276 m3 were dug on the Gem Group in
1959.
An additional two trenches totalling 22 m3 were dug on Nap No. 2 (W
39541) in 1967 and one of 21 m3 in 1968. Anderson Lake Mines Ltd. proposed to
rework the tailings of the mine in 1967. This was approved the next year.
In
May 1972 Rock Ore Exploration and Development entered into an agreement with
Gigantes Exploration Company (subsidiary of Cyprus Mining) and Selco Mining
Corporation. The joint venture drilled three holes in 1974 totalling 275 m and
then was terminated in 1974.
In 1975 Rock Ore and Manitoba Mineral Resources
Ltd. agreed to amalgamate the adjoining Slate Lake and Lilly Lake properties. A
detailed MAG, VLF, and EM survey was carried out in January 1977. Cash payments
were made in lieu of exploration work from 1977 to 1985.
