A souvenir generated to commemorate the official opening of the Algom Uranium Mine near Blind River on 16 February, 1957. The artifact, which measures 15 cm by 10 cm by 1 cm, displays samples of raw uranium ore and two samples of concentrate, one a 170-times concentrate while the other is an 800-times concentrate. All the materials are encased in thick acrylic and no radiation above background can be measured. The artifact had been residing in the vault of the main offices of the Bank of Montreal (BMO) in Montreal and was subsequently donated to the Society by BMO.
