Résumé(disponible en anglais seulement)
The 1.87-1.84 Ga Great Bear magmatic zone is the most prospective belt for iron oxide copper-gold ± uranium deposits currently recognized in Canada. It hosts the 31 Mt Au-Co-Bi-Cu NICO deposit (atypical magnetitegroup IOCG deposit), the 8 Mt Cu-Ag-Au Sue Dianne deposit (typical magnetite- to hematite-group IOCG deposit), and a great variety of associated deposits and prospects. Collectively they span the entire spectrum of IOCG and related deposit types, and demonstrate that the Great Bear magmatic zone is a large-scale IOCG province with major untested exploration potential for base, precious, strategic and nuclear metals. It also
provides a predictive model that is a powerful tool in the search for new deposits.
