In addition to being prospective for base metals mineralisation, both the Eastman and Wirana project areas have potential for gold mineralisation associated with VMS deposits, PGE reefs and quartz veins.
The geology of the areas suggests that a diverse range of Proterozoic (1850-1500Ma) “orogenic” gold deposit models could be considered, such as quartz vein-hosted, shear zone-hosted, BIF-hosted, ironstone-hosted, calc silicate-hosted, black shale-hosted, Coronation Hill Au-PGE and epithermal Au-Cu-Mo deposits.
Previous explorers have noted the potential of the tenement areas for gold deposits (eg, Geopeko and Navigator) but little was done. There has been no systematic effort directed towards exploring either project area for gold. Very minor exploration for orogenic gold deposits has been confined to the eastern end of the Eastman tenement and the north eastern end of the Wirana tenement and was not followed up, despite anomalous sample results.
