Abstract: Exploration Licence 1636 was granted on the 20th September, 1977 and originally extended over an area of 24.6 square kilometres. Subsequent area reductions occurred on 15/05/1980 (to 9.98 square kilometres) and on 21.1.1981 (to 3.326 square kilometres). This report briefly summarises Geopeko's exploration in the licence area by reference to the preceding annual reports. The exploration conducted during the sixth and final year of tenure is also detailed. Through the period 1977-1980 the exploration formed part of a regional program directed towards the search for stratiform base metal occurrences within the Kapalga Formation. The Mt. Bonnie and Iron Blow mixed sulphide' deposits constituted the exploration model and search techniques included airborne magnetometric surveying, detailed geological mapping and rock chip geochemistry. Stephens (1978) reported on the preliminary stages of this work. Latterly, exploration in Exploration. Licence 1636 concentrated on the lower part of the South Alligator Group, especially the Middle Member of the Koolpin Formation which hosts stratiform gold at the Cosmopolitan Rowley and 'Golden Dyke Mines (Sullivan and Iten (1957), Nicholson, 1979). This work was concentrated in the remaining south-western portion of the licence on the northern limb of the Howley anticline where the middle Koolpin lithologies had -been recognised during geological mapping. Exploration for stratiform gold mineralisation' in the period 1981-1983 included stream sediment sampling,' rock chip sampling and detailed geological mapping. 'This work defined three areas which were recommended for further evaluation. In the sixth and final year of tenure exploration was restricted to gridding, soil sampling, geological mapping and magnetic traversing in the central western part of the licence area. This was designed to trace the favourable banded ironstone units from the Cosmopolitan Howley mine into E.L. 1636. Due to the incomplete nature of the evaluation of E.L. 1636, an E.R.L. was applied for to preserve tenure in order to complete the work program outlined in this report.
