Grenville, Faraday (Madawaska Mine)

The Faraday Mine, once a prominent producer of uranium 1954-1964), shut down for a number of years and re-opened as the Madawaska Mine (1976-1982). Here are some excellent specimens from that venerable old locality. These ones were mined in the '50's.

  • A rather large, well formed, twinned crystal of calcite from the famous Faraday (Madawaska) Mine. The crystal is twinned and has a light dusting of hematite. It is rather dinged up and has been oiled in a couple of places. Still, it is quite a crystal.

  • A characteristic calcite crystal in one of the "styles" that calcite occurs in at the Faraday/Madawaska Mine. That is the gemmy-clear scalenohedron with a flat, pinacoidal termination and a dark outer veneer of, probably, an iron oxide. This crystal has another modifying face just below the pinacoid. Very nice! s

  • The faraday Mine is famous for these scalenohedral calcite crystals that have the top of the scalenohedron truncated by a pinacoidal face. Similarly, most of the calcite crystals from this location are coated by an iron oxide. Nice example!

  • A singly terminated scalenohedron from the long-closed Faraday Uranium Mine, a large pegmatite deposit. The crystal is tipical of calcite crystals from the deposit being a pinacoid terminated scalenohedron, coated with iron oxides and including chalcopyrite and pyrite crystals. Very nice example!
