It occurs in a tabular nickeliferous serpentinite, on the margin of an ultramafic intrusive.

Particular floral assemblages associated with highly nickeliferous ultramafic rocks are indicative tools for mineral exploration.

Drilling proved minor intersections of nickeliferous marcasite (MEG 103).

Pristine magmatic massive sulfide are rarely preserved as most deposits of nickeliferous sulfide have been metamorphosed.

Chrysoprase results from the deep weathering or lateritization of nickeliferous serpentinites or other ultramafic ophiolite rocks.

The orebody itself is composed of 2 to 6 metres of massive nickeliferous sulfides, usually banded and foliated pentlandite-pyrrhotite-pyrite.

It is formed in this way by removal of sulfur from pentlandite or other nickeliferous sulfide minerals during metamorphism or metasomatism.

Minerals associated with chaoite include: graphite, zircon, rutile, pseudobrookite, magnetite, nickeliferous pyrrhotite and baddeleyite.

The nickel resources of the region are in the form of nickeliferous laterites, soils of unique geochemistry derived from the tropical weathering of parent serpentinized ultramafites.

Drilling at Ballantrae by Selection Trust Ltd found disseminated and massive nickeliferous marcasite over widths of a few metres (MEG 103).

Massive nickeliferous sulfide is composed of greater than 95% sulfide occasionally with exotic enclaves of olivine, metasedimentary or melted material derived from the footwall to the lava flow.

In sulfide undersaturated melts, Ni substitutes for other transition metals within ferromagnesian minerals, the most usual being olivine, although nickeliferous varieties of amphibole, biotite, pyroxene and spinel are known.

At present exploration companies are much interested in the nickeliferous laterites that overlie the serpentinites on Santa Isabel, and geochemical work has revealed a number of nickel and other metal anomalies that warrant further attention.

Kings Euthydemus, Euthydemus II, Agathocles and Pantaleon made these coin issues around 170 BC and it has alternatively been suggested that a nickeliferous copper ore was the source from mines at Anarak.

The advantage of heap leach treatment of nickeliferous laterite ores is that the plant and mine infrastructure are much cheaper - up to 25% of the cost of a HPAL plant - and less risky from a technological point of view.
