Navigator retains three projects in the East Kimberley area, which formed the basis of its IPO in 2003. The projects are the Cummins Range Rare Earth Project, the Eastman Project and the Laura River Project.
Navigator owns 100% of the Cummins Range Project, more information on which can be found on a dedicated page by clicking here.
Navigator joint ventured the Eastman and Laura River projects to Magma Metals Ltd (Magma) in 2006 in order to be able to focus on the Leonora Gold Project. Magma has since earnt 70% interest in both projects, with Navigator retaining a 30% free-carried interest to a decision to mine.
Eastman – 30% Navigator (free carried), 70% Magma Metals
The 260km2 Eastman Project is located 115km southwest of Halls Creek, in the East Kimberley region of Western Australia.
Eastman is prospective for both nickel-copper-platinum group metal mineralisation, associated with the 17km long Eastman Bore mafic-ultramafic intrusion; and for volcanogenic mass sulphide copper-zinc-lead-silver-gold mineralisation, associated with the Koongie Park Formation which is a sequence of felsic volcanic rocks and sediments including banded iron-formation, chert and carbonate rocks.
In January 2007, Magma announced a maiden inferred JORC compliant resource at Eastman, consisting of 1.5 million tonnes of ore grading 1.8% Zn and 0.7% Cu, 0.7% Pb and 15.7g/t Ag.
Laura River – 30% Navigator (free carried), 70% Magma Metals
The 160km2 Laura River Project is just 35km southwest of Halls Creek on the Great Northern Highway in the East Kimberley of Western Australia.
Laura River is prospective for several different types of mineralisation including: Ni-Cu-PGM mineralisation associated with the mafic-ultramafic intrusions; Cu-Zn-Pb-Ag-Au mineralisation associated with the Koongie Park Formation; and Cu-Au mineralisation associated with the Tickalara Metamorphics.
Within the Project area, the structural fabric is dominated by the northeast trending Laura River, Mary River and Lamboo Faults and east-west trending link faults; these structures are prospective for high grade gold mineralisation.
A recently completed diamond drill hole at the Amphitheatre prospect at Laura River has indicated that both Laura River and Eastman are also prospective for iron ore associated with iron-formations.
