I was asked to examine 61 thin sections from the Horne of Bullion mine area east of Barrow Creek, Northern Territory. The thin sections were of rocks from an area believed to be prospective for Au ± Cu mineralisation of early Proterozoic age and possibly analogous to mineralisation styles similar to that found in other Proterozoic belts such as Cloncurry, Tennant Creek and the Granites/Tanami. This report is divided into 3 sections. Section 1 comprises a synthesis of the thin sections examined, Section 2 contains a discussion of the regional factors, whilst Section 3 discusses some implications for mineralisation. Appendix 1 contains brief petrographic descriptions of the thin sections supplied. In preparing this report, I have consulted with Dr Gladys Warren (because of her experience with granitic and metamorphic rocks of the Amnta Region, and her experience in the Barrow Creek area) and Dr Dean Hoatson (because of his experience with Precambrian layered intrusions including the Munni Munni Complex of the Pilbara Block and various Palaeoproterozoic mafic intrusions of the Halls Creek Inlier). However, all interpretations presented in this report are my own.
