The ∼0.83 Ga Jinchuan magmatic Ni-Cu-PGE deposit emplaced during initiation of Rodinia breakup.

Ore occurs as disseminated and net-textured sulphides in dunite cores of a larger lherzolite sill.

Parental picritic basalt magma segregated in large staging chamber before injection into the sill.

This magma generated as high degree melting of enriched SCLM by an anomalously hot mantle plume.

Extensive post-magmatic alteration significantly modified the intrusion and mineralisation.
