Resources
The Greenvale Nickel Laterite Mine began production in 1974 and ceased in 1993. A scoping study conducted by Anaconda Nickel Limited reported a remnant resource of 44 Mt @ 0.9% Ni and 0.1% Co at the Greenvale Nickel Mine.
The Lucknow nickel deposit represents the partial lateritisation of weathered serpentinite associated with shearing of the underlying meta-gabbro. Garnierite-serpentine mineralisation is hosted by the shear and grades between 0.3% to 0.4% nickel. The surface extent of the lateritic nickel anomaly at the Lucknow deposit extends approximately 2500 m by 800 m within a larger lateritic plateau on a northwest trending ridge. The best nickel and cobalt grades are associated with the laterite and the upper parts of the serpentinite.
