Age constraints and geochemical evolution of the Neoarchean mafic–ultramafic Wabassi Intrusive Complex in the Miminiska–Fort Hope greenstone belt, Superior Province, Canada

• Max, Wabassi Main, and Wabassi South intrusions form the Wabassi Intrusive Complex. • Wabassi Intrusive Complex formed between 2728 and 2727Ma. • All parental magmas are basaltic (up to ∼12% MgO). • Max intrusion may be the most prospective area for Ni–Cu–(PGE) exploration. • Oxtoby Lake intrusion...

• Max, Wabassi Main, and Wabassi South intrusions form the Wabassi Intrusive Complex. • Wabassi Intrusive Complex formed between 2728 and 2727Ma. • All parental magmas are basaltic (up to ∼12% MgO). • Max intrusion may be the most prospective area for Ni–Cu–(PGE) exploration. • Oxtoby Lake intrusion younger (2717Ma) and unrelated to Wabassi Intrusive Complex.
