Heazlewoodite is a rare nickel sulfide. It is a mineral of hydrothermal origin that is found in serpentinites, associated in particular with pentlandite and millerite, it is also sometimes found in the nickel deposits of komatiites. It owes its name to its locality of discovery : Heazlewood (Tasmania, Australia). Heazlewoodite appears in fine-grained masses, very rarely as tiny crystals, of a pale brass yellow to pale bronze hue.
