The Honeymoon nickel sulphide deposits are located 45 km
south of Wiluna in the 2.7 Ga old Agnew-Wiluna greenstone belt
in the NE of the Yilgarn Craton (Figure 1). Both disseminated
and massive nickel sulphide deposits are present within the
deformed and metamorphosed Honeymoon Well ultramafic
complex and are hosted by distinctly different komatiitic
lithologies (Gole et al, 1996). The deposit styles and host rock
lithologies reflect formation in markedly different volcanic
settings. Metasomatism has affected parts of the ultramafic
complex, including sections of the sulphide deposits, and has had
a marked impact on mineralogy and bulk sulphide compositions. The present indicated resource is 158 Mt at 0.71 per cent Ni in
four deposits (0.4 per cent Ni cut-off, resources above 300 m
depth, December 1995). This includes a massive sulphide
resource of 2.5 Mt at 3.36 per cent Ni.
