Results from the recently completed gravity survey (7 km x 10 km at 200 m x 200 m) provide detailed targeting for a second stage drilling programme at the Herakleion Copper-Gold prospect in South Australia. Four focus areas are defined within a structurally complex body of rocks with high density. Interpretation of the additional gravity data, using density parameters established by the 2003 drilling, indicate rocks of densities of approximately 3.2 g/cm3 underlie the four focus areas at depths of 425 m to 500 m below surface. Drill hole HD-02 (drilled in 2003) is correctly sited at one of the focus areas. Gravity data available at the time of the drilling had been interpreted by RLC to indicate rocks of 4 g/cm3 at a depth of 150 m – 250 m below surface. The hole (HD-02) was terminated at 399.25 m depth whilst still in Upper Proterozoic cover sequences. Densities of 3.2 g/cm3 are consistent with the bulk densities of the iron rich breccias which host the Iron Oxide Copper Gold (“IOCG”) mineralization at both: Olympic Dam Mine (250 km to the SE) and Prominent Hill Prospect (150 km SW). Herakleion is further supported by the presence of copper mineralization at surface – such mineralization being absent at surface at both Olympic Dam and Prominent Hill. The Board of Redport is considering Second Stage drilling – this may include deepening HD-02 and is subject to approval and funding by the ECBMJV parties, and drill availability.
