Geological Setting and Mineralisation

The Koa project area is located at the southern extent of the Areachap and Kaaien Terranes, Namaqualand Metamorphic Province (NMP) (Figure 19).

The Areachap Terrane comprises a 280 km long NNW-trending belt that represents a 1.3 to 1.24 Ga old, highly metamorphosed and deformed remnant of a mature volcanic arc accreted onto the Kaapvaal Craton.

The Areachap Terrane hosts at least 20 known stratabound to stratiform volcanogenic massive to semi-massive sulphide deposits and occurrences (VMS), including the Prieska deposit (JORC resource of 27.8 Mt at 1.22% Cu, 3.93% Zn and 0.20g/t Au), located 15 km north of the Koa Project.

At Koa the Areachap and Kaaien Terranes are covered by a thin veneer of tillites of the basal Dwyka Formation of the Permian Karoo Sequence and intruded by numerous Karoo-age dolerite dykes and sills (Figure 20)
