Annual report on EL 5050 Emerald Springs East

Abstract

Exploration in EL 5050 was directed at assessing the potential of the Early Proterozoic Koolpin, Gerowie Tuff, Mt Bonnie and Burrell Creek Formations for epigenetic gold deposits in quartz vein lodes. Attention was also given to syngenetic, stratigraphically controlled gold bearing sulphide lenses in the Mt Bonnie Formation similar to known mineralisation in the Iron Blow and Mt Bonnie mines. The tenement lies in the northern part of the Pine Creek mineral field on the eastern flank of the Burrundie Dome, close to outcrop of the McMinns Creek Granite and just west of the southern extension of the Pine Creek Shear Zone. Separate gold and tin occurrences are found in the vicinity of the tenement. Geological mapping and rock chip sampling identified three areas of good potential for epigenetic gold within the Bonnie Formation, associated with anticlinal axes and faulting. Some potential was also recognised in a contact zone of Zamu Dolerite and Gerowie Tuff. Gold assays up to 4 ppm were recorded in these zones. Follow up detailed mapping, costeaning and diamond drilling has been recommended to further define the potential of these areas.
