| Abstract | The history of the discovery and development of the niobium (columbium) and tantalum resources of Canada has spanned ninety years (1882-1972) during which these minerals advanced from being mineral
curiosities, through the stage of being the byproduct of other commodity searches and are now the main product of two mines, Occurrences and deposits of niobium and tantalum have been reported from most province5 and territories of Canada, At least
256 deposits are known and of these 12 have published reserves of niobium and 3 estimates for tantalum: 172 of the deposits are pegmatitic , 64 are alkaline syenite-carbonatite complexes, 3 are p l acers , and 17 are u11defined types, The complexes
have become the most promising source of future mining production since their geological characteristics were first recognized in the early l 950 ' s . Niobium (pyrochlore) concentrates have been mined at Oka, Quebec by the St. Lawrence Columbium and
Metals Corporation from an a lkaline syenite - carbonatite complex since 1961. Tantalum (wodginite) has been .recovered from a large zoned granite pegmatite at Bernie Lake, Manitoba by the Tantalum Mining Corporation of Canada since 1969. |
