EL 7313 Rosie Creek report for the 12 months ended 21 February 1994

Abstract

Previous interpretation of the regional gravity and magnetic data suggested that the Rosie Creek area has structural and stratigraphic elements in common with those at the HYC Pb-Zn deposit. Drilling by Geopeko, targetted on EM anomalies, has intersected likely McArthur Gp sediments. Unconfirmed correlation with the Umbolooga Subgroup. The work completed within the licence area during the last anniversary period included the construction of 54 line kms of track access, a gravity survey (interpretation incomplete), 36 line km Sirotem and 5 drill holes totalling 1015.7m to test EM anomalies. The drill holes failed to intersect any bedrock conductors and downhole TEM failed to identify any off hole conductors. It is inferred from these results that the apparent EM conductors were due to variations in conductivity of the cover sequence.
