OREAS 196

OREAS 196 has been prepared from a blend of classic Ni-Co laterites, comprising goethite-hosted limonite ores and garnierite/serpentine-rich saprolite ores sourced from the north-eastern Goldfields of Western Australia and the north-east of South Sulawesi Province, Indonesia. Mineralisation has developed through the weathering of ultramafic rocks, including komatiite, peridotite and dunite. Nickel is concentrated in both the limonite and saprolite zones. The limonite zone, rich in goethite, hosts most of the cobalt content. The saprolite zone contains the majority of the nickel, primarily occurring in silicate minerals such as garnierite, serpentine, and smectite. Secondary minerals, including chromite, magnetite, hematite, and manganese oxides (e.g. asbolane or wad), are also present.

Twenty-six commercial analytical laboratories participated in the program to certify the elements reported below:

  • Lithium borate fusion whole rock analysis package with X-ray fluorescence
  • Thermogravimetry: Loss on Ignition (LOI) at 1000 °C
  • Sodium peroxide/borate fusion with full suite ICP-OES or ICP-MS elemental packages
  • Total C and S by infrared combustion furnace

Homogeneity was assessed using XRF analysis on 12 pulp samples (20 g each) from six sampling units. An ANOVA test was performed to compare within- and between-unit variances, providing a statistical measure of uniformity and confirming that all units belong to the same population.
