St Lawrence Columbium Mine, Oka complex, Oka, Deux-Montagnes RCM, Laurentides, Québec, Canada

Latitude: 45°30'4"N
Longitude: 74°1'49"W
Formerly: St Lawrence Columbium Mine, Oka, Oka complex, Deux-Montagnes Co., Québec, Canada

Inactive niobium mine with two open pits and underground workings (now water filled), in the Oka carbonatite complex. The mine opened in 1961 and ceased opertions around 1977. During its operation it was one of largest niobium mines in the world. Significant reserves of pyrochlore (the main ore mineral)remain at the deposit. La Trappe, shown in the earlier locality hierarchy is incorrect. It is a nearby monastery and has nothing to do with the mine.
