I bought this at my LCS from the foreign coin bin for $3.
It is a 1967 Confederation token from the Province of
Ontario Commemorating the Role of Mining in the
Development of Canada and made from Gold, Nickel, Zinc,
Platinum, Silver, Copper, and Iron mined in Ontario.
I worked in the gold mines of Nova Scotia and northern
Ontario near Wawa and Balmertown, as a geologist in
the late 1980's. The miner in the scene is operating a
stoper, a drilling jackhammer that sinks holes into the
roof of a tunnel or stope. It is a heavy, loud, fog
inducing machine that is fueled by compressed air and
water, that hammers and drills and extends a bit and rod
into the rock, spewing water, sludge and rock cuttings at
the operator. Full on slickers are necessary to stand
under this shower of water and sludge all day. Then load
the holes with powder and sticks of dynamite and blow it
up at the end of the shift. Tough people do this job.
The ore is then taken out to a level that the miners and
their stopers can get in and drill the next level out of
the roof, and on it goes.


I see this was discussed and the medal was tested for
precious metal content with little found.
