Elliot Lake deposits, Ontario, Canada

Brannerite is the third most important reduced uranium mineral in that it occurs in many different types of deposits and is the chief uranium producer in the conglomerates of Blind River-Elliot Lake, Ontario, Canada. Although it has been found in pegmatites, hydrothermal and sedimentary deposits, it is always associated with uraninite and probably forms through reactions with uraninite and titanium phases that are also present.
