[url]Niobium (Columbium) deposits are documented at "James Bay Pyrochlore." Niobium Columbium is present at a grade sufficient to have a strong effect on the economics of an excavation project. It may even be viable as the only commodity mined.

1 Deposit THERE ARE NO EXISTING FACILITIES AT THE SITE. BEFORE OPERATIONS COULD START, AN ACCESS ROAD OF 40KM TO THE RAIL- STATION AT MOOSE RIVER WOULD HAVE TO BE CONSTRUCTED ALONG WITH A 25KV TRANSMISSION LINE OF 40KM AND TRUCK LOADING AND UNLOADING FACILITES ALSO AT THE RAIL STATION AT MOOSE RIVER.
1 Geology THE JAMES BAY PYROCHLORE COMPLEX APPEARS TO BE THE RESULT OF A MULTIPLE INTRUSION OF SEGREGATED PYROXENITE- CARBONATITE MAGMA INJECTED IN A SERIES OF PULSES INTO AN EXISTING FAULT ZONE. THE FIRST PULSE IS REPRESENTED BY PYROXENITE, FOLLOWED BY A SECOND, OF CALCITIC CARBONATITE, CONTAINING PHLOGOPITE, SODA AMPHIBOLE AND PYROCHLORE. THE OREBODY OCCURS AT THE INTERSECTION OF THE RIFT WITH A NORTH-SOUTH FAULT THAT MODIFIES THE STRIKE OF THE RIFT.
