Robex Resources Inc. is pleased to announce that the final report from the independent Australian firm, RSG Global Inc, indicates an inferred gold resource of 760,000oz of gold at an average grade of 0.9 g/t Au, on Nampala, located on the Mininko property, South Mali, West Africa.
RSGâ€™s preliminary report from last April had established the resource at 735,000oz at an average grade of 0.9 g/t Au.
The following table shows the specifications of RSG Globalâ€™s resource calculation.
Total inferred gold resource for the Nampala Gold Deposit
Lower Cutoff Grade g/tAu, M tons, Average grade – g/tAu, Onces of gold
0,5 26,872 0,9 760000
0,6 20,082 1,0 641000
RSGâ€™s resource calculation was based on the following:
83 Rab holes for a total of 3,571 metres drilled;
38 AC holes for a total of 3,618 metres drilled;
148 RC holes for a total of 15,788 metres drilled;
7 DDH holes for a total of 1,155 metres drilled.
Drilling on Nampala has so far mostly focused on the first 100 metres. The deposit remains open to the north, the west and at depth. The few holes crossing the 100-metre level have intersected the mineralized tonalite, presenting a potential for mineralization at depth â€“ for example, drill hole NRC 602 graded 12m at 1.58g/t between 119 metres and 131 metres. The Nampala property is located between the Morila Mine, which has already produced over 4 Moz of gold and still has approximately 2.8 Moz of resources and the Syama Mine, 6 Moz at an average grade of 3 g/t.
The Mininko property is located on the northern border of the Archaean-Proterozoic Leo Shield, which forms the southern half of the West African Craton and is enclosed within the shale unit of the BagoÃ© Formation of the Birimian Group (Lower Proterozoic).
Mineralization in the Nampala deposit is similar to the mesothermal quartz-carbonate vein gold deposit type. Mineralization is hosted by a turbiditic sequence centred on an intrusive plug of intermediate to felsic affinity (tonalite and granodiorite) emplaced within a NNE regional structure. Gold is located mainly within the three lenses and is closely associated with arsenopyrite and silica alteration.
