The Spargoville Group comprise a number of nickel prospects (with minor copper), and small mines, discovered in the late 1960's by Selcast Exploration Ltd. They are concentrated some 5 kilometres south of the Coolgardie-Norseman Hwy/ Goldfields Hwy junction. They are within a couple of kilometres west of the Coolgardie-Norseman Highway, and west of the Emu Rocks location bordering the road. The Wattle Dam mine is within the immediate area also.
1A contains 0.365 Mt at 2.53 Ni. Amalg Resources NL conducted some mining at the location between 1990 to 1992. A shaft was sunk, and 27 000 tonnes of nickel sulphide ore was mined.
Generally speaking the Spargoville Group is at the northern end of the structurally complex Widgiemooltha Greenstone Belt, of linear tightly folded mafic-ultramafic rocks and chert, on the south-east flank of the Depot Dome. The ultramafic rocks include spinifex textured komatiite, altered to tremolite, chlorite and talc. Metasedimentary rocks close to the faulted contact with the ultramafic rocks are laminated, micaceous, quartzo-feldspathic schist with varying amounts of biotite.
1a shows gossans with disseminated and massive sulphide in an embayment structure at the basal amphibolite contact. The deposit consists of three small shoots, in a lens of steep west dipping metamorphosed olivine peridotite, 500 metres long, and 160 metre thick. Within this is a 10 metre layer of tremolite and chloritic ultramafic rock, overlying metamorphic olivine, anthophyllite, talc, carbonate rocks, underlying Footwall amphibolite. Fine grained disseminated to matrix sulphides grading 1-6% Ni.
