Geology & Mineralization OSINO RESOURCES Cm-scale quartz sulphide veins in schist Brecciation and silicification in quartzite Pyrrhotite Pyrrhotite in brecciated quartz vein Arsenopyrite Arsenopyrite in cm scale veinlet in schist Pyrite Sediment-hosted, orogenic (structurally controlled) Au deposit Thick package of turbidites and calcareous sediments were buried and deformed during the late Proterozoic Damara orogeny Metal bearing brines were expelled from the deep sedimentary basin and driven towards the southern margin which is defined by a basement cored anticline Hydrothermal fluids were channelled upwards in the basin margin fault and out into the lower stress splay structures Gold deposition mainly in a zone of intense folding and faulting adjacent to the basin margin. Host rocks include biotite and muscovite schist (Au in quartz- sulphide veins parallel or sub-parallel to foliation) and quartzite and turbidite (Au in breccia, stockwork and cross cutting quartz - sulphide veins) Gold mineralization is associated with three sulphide phases, namely pyrrhotite, arsenopyrite and pyrite Several zones of pervasive alteration and replacement by silica- rich fluids and sulphides have been intersected. These replacement zones appear to host higher gold grades Detailed petrography & mineralogy samples submitted for better understanding of the Au associations and deportment.
