Tampia is hosted within Archaean mafic-felsic granulite facies units. Gold mineralisation is hosted within a mafic gneiss unit dominated by pyroxeneplagioclase - amphibole minerals. Late granitic sills intrude the mafic gneiss. Gold mineralisation occurs as shallow dipping (20°-30°), 2-20m thick lode zones subparallel to the granitic sills. Gold mineralisation of associated with disseminated pyrrhotite, arsenopyrite, chalcopyrite and rare pyrite.Alteration includes silica, microcline, hornblende and clinopyroxene. Gold mineralisation is associated with disseminated pyrrhotite, arsenopyrite, chalcopyrite and rare pyrite. Total sulphide content of mineralised zones is typically 1-3%. Arsenic grade is a good indicator of gold mineralisation, which is frequently nuggety. The resource covers an area of 900m x 500m.DimensionsThe deposit has a strike of 1000m, down-dip width of around 400m and depth extent of around 150m. The mafic gneiss, granite sills and mineralised lodes have a shallow SE dipping, gently folded orientation forming a ‘bowl’ shaped geometry.Lode and shear hosted styles. Strikes range from 140m (Dugite) to 450m (Golden Orb) and dip at 70-90°. Average lode width approximately 10m, mostly ranging between 2- 20m. Down-dip extents typically 50-75m.
