The mineral deposits on the property include Salman Trend and Adamus deposits and also several smaller deposits (Bokrobo, Akropon, Nfutu, Aliva and Avrebo). Salman Trend gold deposits are believed to be associated with the same beltmargin shear zones that host the other Ashanti Belt gold deposits and has many characteristics typical of these deposits.

Major gold deposits in Ghana are hosted by proterozoic rocks of the West African Craton, including the Birimian Supergroup, a series of metavolcanic and metasedimentary rocks, the Tarkwaian Group, comprising fluvial metasedimentary rocks, and various gabbroic to granitic intrusives. Gold mineralization within the Birimian Supergroup is structurally controlled and associated with mesothermal quartz veins and sulphide concentrations, while both mesothermal shear hosted and palaeoplacer gold deposits occur in the Tarkwaian Group. The Nzema Project is within the Birimian Supergroup rocks with minor granitic intrusions, bounded by large granitoid bodies to the west and east, and is devoid of Tarkwaian Group rocks.

The Salman Trend is defined by a semi continuous +200ppb gold in soil anomaly extending for at least 9 kilometres along the Salman Shear Zone. Approximately 8.5 kilometres of strike extent has been drill tested to date with several discrete, multi-lode gold deposits identified along the shear zone. Significant oxide gold deposits within the Salman Trend include, from south to north, Salman South, Salm ........

The mining method is conventional open pit mining including drilling, blasting, loading and hauling operations carried out by a contractor. Mining is currently taking place in the Salman Trend on oxide and upper transition material and also at the Adamus pit.

Cumulative mining capacity of the fleet provided by AMS meets the earthmoving requirements of the mining schedule as generated by Nzema technical management and properly supports mining operations. The in-pit material excavation is largely conducted by two Liebherr 984C back-hoe excavators equipped with 7m3 buckets (main production units). Waste and near-pit ore haulage is mainly conducted by CAT 777 off-highway trucks; and material hauled out of smaller satellite pits utilizes articulated Volvo A35F trucks.

Drilling and blasting is performed on 6 to 15m benches, depending on geological and geotechnical settings of a given deposit, with blasted material excavated in discrete 3m high flitches.

The Nzema processing plant is designed to treat oxide, transition and primary ores from the various pits. The design throughput treatment rate depends on the hardness of the ore with 2.1 Mtpa of softer oxide ore and 1.6 Mtpa of the harder transition and fresh ore. The plant has been operating since February 2011 and achieved commercial production in April 2011. The average throughput rate is currently 2.1 Mtpa given the mix of ore feed.

The treatment plant flow sheet is based on single stage crushing, single stage 3.5MW SAG milling, gravity recovery of free gold from a portion of the cyclone underflow using Falcon 5200 followed by an Inline Leach Reactor (ILR) to treat the gravity concentrate and a six stage carbon-in-leach (CIL) circuit to treat cyclone overflow as leach feed. The treatment circuit also includes a Counter Current Decantation circuit (CCD) for the recovery of cyanide from the tails slurry via thickening and decants return dilution to achieve less than 50 ppm ........
