Mariners is renowned for its extremely high arsenic contents, with common arsenopyrite, nickeline, gersdorffite and other arseno-sulfide minerals common in the ore during the earlier years of mining.

One example of this is the Widgiemooltha Dome, where carbonated hematite-bearing siliceous basalts containing native gold, arsenopyrite, nickeline and gersdorffite are encountered in the footwall of the Miitel nickel mine.

Gersdorffite has three crystallisation forms : Gersdorffite-P2 1 3 ( NiAsS ), Gersdorffite-Pa3 ( Ni ( As, S ) 2 ) and Gersdorffite-Pca2 1 ( NiAsS ).

Gersdorffite belongs to a solid solution series with cobaltite, CoAsS . Antimony freely substitutes also leading to ullmannite, NiSbS . It has a Mohs hardness of 5.5 and a specific gravity of 5.9 to 6.33.

At the Hilton Mine, Cumbria, England, k�ttigite has been found in a specimen of galena PbS and gersdorffite NiAsS ( but no sphalerite ), on a surface coated with annabergite Ni 3 ( AsO 4 ) 2 ?H 2 O and an earthy crust.
