The Sinclair Nickel Project includes an extensive 290km2 tenement package covering at least five known ultra-mafic volcanic sequences that are considered prospective for massive nickel sulphide mineralisation.
Numerous nickel occurrences have been identified through historical drilling, geochemical and geophysical surveys across the project, with key targets shown in the figure below.

The style of mineralisation likely to be found at Sinclair is Type-I Archean Komatiite hosted nickel sulphide deposits. These deposits, similar to those found throughout the greater Norseman-Wiluna Greenstone Belt, are accumulations of nickel sulphides at the base of Komatiite lava channel flows that occurred over 2.5-2.8 billion years ago. These accumulations of nickel sulphides are conductive and can be remotely detected by electro-magnetic (EM) surveys and geochemical analysis of overlying soils.
