Jessievale IOCG Project

Jessievale IOCG Project

Jessievale EPM 16078 is located 48 km north-northwest of Cloncurry in northwest Queensland. The EPM comprises four sub-blocks that cover an area of 13 sq km.

Work by Western Mining Corporation involved interpretation of aeromagnetic data, compilation of previous exploration results, and a regional gravity survey with later infill at 200 x 400m spacing. The gravity survey found an anomaly trending north-south for 7 km in the eastern part of their tenement. In 1999, the tenement was assigned to BHP and in 2000, after reviewing WMC’s exploration results farmed out the tenement to Noranda Pacific Pty Ltd. Three diamond holes were drilled to test coincident magnetic and TEM anomalies. The holes intersected massive magnetite and strong zones of pyrite-pyrrhotite several metres wide, with trace chalcopyrite mineralisation.

The Jessievale EPM is located within the Ernest Henry magnetic terrane, nearly 31 km northwest of the Ernest Henry Mine (166 Mt at 1.1% Cu, 0.54 g/t Au). Despite being investigated by other explorers, it remains prospective for IOCG mineralisation within Proterozoic basement rocks, which are concealed by up to 60m of younger Mesozoic-Cainozoic cover. Several structures are obvious from the geophysical data, some of which could be major pathways for mineralising fluids.

Wide spaced drilling by previous explorers outlined several zones of anomalous Cu and Zn geochemistry within Proterozoic basement rocks at the Jessievale and Cattle Creek Prospects. The zones of anomalous geochemistry have not been fully tested at depth and warrant follow-up investigations.
