EL 5235 Final report for the period 16 March 1988 to 24 December 1993 Osborne Range Prospect

Abstract

During the period of the licence, 2378 soil and 40 rock chip samples were collected. In addition 857 vacuum drill holes (3428m), 40 Percussion (1204m) and 15 RC holes (902m) were completed. The licence was, in part geologically mapped and 217km of ground magnetics were completed, along with 944 IP reading, resistivity set up, petrology, airborne magnetics and TM acquisition and interpretation. The soil sampling outlined two anomalous zones Kroda 1-Tulip and NW Petricks. Follow up outlined several NW trending anomalies. Vacuum drilling was designed to test the soil anomalies. Three anomalies C1, C2 and C3 were defined in a 5km zone striking NW (peak gold value 1530ppb Au). RC drilling of the C3 anomaly returned a large number of low grade gold values eg: (1m at 0.47g-tAu). RAB drilling at C1 returned grades greater than 1g-t including 6m at 3.5g-t Au. RAB results at C2 and C3 were disappointing.
