Tampia is hosted within Archaean mafic-felsic granulite facies units. Gold mineralisation is hosted within a mafic gneiss unit dominated by pyroxene-plagioclase-amphibole minerals. Late granitic sills intrude the mafic gneiss. Gold mineralisation occurs as shallow dipping (20°- 30°), 2-20m thick lode zones, sub-parallel to the granitic sills.

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.

The mafic gniess, granite sills and mineralised lodes have a shallow SE dipping, gently folded orientation forming a ‘bowl’ shaped geometry.

The deposit has a strike of 1000m, down-dip width of around 400m and depth extent of around 150m.

Mining method is conventional open-pit with drill and blast, excavate, load and haul.

Processing will take place at the Edna May gold mine.

The original processing method incorporated gravity recovery, flotation, ultra-fine grinding, and enhanced leaching to treat the more refractory elements of the ore, with carbon-in-leach (CIL) being used to treat the flotation and enhanced leach tailings product.

The revised milling process for Tampia uses a simpler, more conventional gravity recovery and CIL process at a moderately finer grind size of 125um.

Overall recovery of ore grade material using standard CIL method is estimated to be in the 80-90% range.
