Fraser Range Project

Through its history as a Mark Creasy-controlled company, Galileo has amassed a 67% interest in Fraser Range tenements and is actively exploring for magmatic massive sulphide- nickel-copper deposits.
The Fraser Range project covers exploration licences totalling 492 km2 in the Albany-Fraser Orogen. The Albany-Fraser Orogen is dominated by the northeast-trending Fraser Zone, a suite of high-grade metamorphic rocks that have a distinct geophysical signature in both aeromagnetic and gravity data. The Fraser Zone comprises mainly metagabbroic rocks interlayered with sheets of granitic gneisses.
Galileo’s Fraser Range project is located across two areas – the northern Kitchener zone which hosts the company’s Lantern and Nightmarch prospects and the southern Yardilla zone, which holds the Empire Rose and Yardilla South prospects.
The project is well positioned within the nickel-copper bearing Fraser Range Zone, with the Nova Bollinger and Silver Knight deposits located between the two Galileo-controlled areas. The location also offers excellent access to infrastructure, with the main Eyre highway immediately south of the Fraser Range project area.
The northern tenement, Kitchener (230 km east of Kalgoorlie), is accessible via the heavy vehicle Trans-Access Road running parallel to the Trans-Australia Railway line. Drive time from Kalgoorlie is approximately two and a half hours with numerous four-wheel drive tracks allowing access to exploration areas.
The Kitchener area to the northeast of Yardilla is prospective for nickel and copper mineralisation in mafic rocks and is completely covered by transported Quaternary aeolian sands and Tertiary coastal and marine sediments of the Eucla Basin. Based on geological and geophysical interpretation by the Geological survey of Western Australia, the area is dominated by strongly metamorphosed metagabbro, metagranite and minor metasedimentary rocks of the Fraser Zone.
The southern Yardilla group of three tenements (100km east of Norseman), straddle the Eyre Highway east of Norseman as well as the Fraser Fault which separates the Fraser Zone from the adjoining older Biranup Zone to the west. Well maintained station tracks provide easy access from the bitumen highway to exploration sites with total travel time from Kalgoorlie being approximately three hours.
The Yardilla tenements straddle two Proterozoic domains separated by the Fraser Fault. The north-western domain of the Yardilla area is dominated by metasedimentary rocks with minor granite gneiss and is interpreted to be part of the Paleoproterozoic Biranup Zone. The south-eastern magnetic domain is hosted by layered mafic series of the Fraser Zone comprising mainly gabbronorite and gabbro. The mafic rocks are interleaved with granite gneiss and felsic to intermediate gneiss, all metamorphosed at granulite facies.
Historical drilling by Newmont in the south of the Yardilla tenement block intersected 0.2-1% nickel in a number of drill holes and elevated copper readings, indicating potential for massive nickel sulphides. The Yardilla area is also prospective for gold, which can occur within metamorphosed rocks associated with hydrothermal alteration.
