Hassai South

A single lens some 1,400 m long and 5-20 m wide, dipping 60°S and extending to at least 550 m. Geophysical surveys indicate possible extensions to over 700 m. The upper, oxide portion has been mined as gold-bearing SBR ore, with supergene ore grading over 5% copper at the base of the pit.

Hadal Awatib

The largest of the known deposits, although apparently broken into multiple lenses at Hadal Awatib East, West and North, all of which have supported mining of gold ore from the oxide zone, for total production in excess of 1 Million oz. The total strike length exceeds 2,000 m, with widths of up to 100 meters. Depth extensions have been drill-tested to 400 m with geophysical signature down to at least 800 m. Dip is sub-vertical.

Hadayamet

The geological model is defi ned as an accumulation of multiple lenses globally orientated N070 and dipping 70°N. Overall dimensions of the deposit are 700 m of length, recognised in the sulphide zone up to 300 m in length, up to 130 metres of thickness with a vertical extension of 250 m.

Others

Other deposits such as Taladeirut, Adassedekh, Oderuk and Onur have undergone minimal drill testing at this stage, but interpretation of geophysical data suggests strike lengths of a few hundred metres, thicknesses of 15 to 40 m and good depth extent in all cases. Drilling has indicated supergene and primary sulphide mineralisation with a range of Cu/Zn ratios and generally minor gold in primary sulphides
