Twelve Ontario Minerals — Vintage Radioactive Mineral Teaching Set

A complete, original vintage specimen set illustrating twelve radioactive and rare-earth minerals from Ontario's uranium-bearing pegmatites — the Grenville Province terrain that made the Bancroft area, once dubbed the "Mineral Capital of Canada," the site of the greatest uranium prospecting rush in the world during the 1950s.

This boxed set retains its original numbered display card and typed identification key, pairing each specimen to its species:

1. Uranothorite
2. Uraninite
3. Betafite
4. Euxenite
5. Brannerite
6. Thorite
7. Uranophane
8. Zircon — Cyrtolite
9. Thorite
10. Allanite
11. Pitchblende
12. Melanocerite

Together, these twelve species represent the core radioactive mineral suite associated with Ontario's Bancroft-area uranium mines and pegmatites — properties like the Cardiff, Faraday/Madawaska, Bicroft, and Fission deposits that were actively explored and mined for uranium ore, radium, and thorium from the 1920s through the 1970s. The set spans the range of radioactive mineral chemistry found in the region: primary uranium oxide (uraninite/pitchblende), secondary uranyl silicate (uranophane), niobate-titanates (euxenite, betafite, brannerite), and rare-earth-thorium silicates (thorite, allanite, melanocerite) — a genuinely comprehensive cross-section for anyone studying uranium mineralogy or the geological history of the region.

Sets like this were produced as educational reference material, likely for institutional, school, or museum teaching use, and complete examples with original identification cards and intact specimen counts have become increasingly hard to find as individual pieces are broken out and sold separately over the decades. This set is complete, with all twelve numbered specimens present and matched to their original card.
