Further results from reverse circulation drilling are awaited.\nThe results confirm the economic potential of the tailings, and the existence of further exploration targets suitable for early follow-up in the eastern license and at Nyarongi.\nhttp://www.rns-pdf.londonstockexchange.com/rns/7428K_-2010-4-23.pdf\nApproximately 458 metres were drilled on the tailings dam (32 holes on a 25x25 metre grid with 6 infill holes). Drill depth varied across all hole between a maximum of 20 metres and minimum of 6 metres. Two holes only reached 1.5 metres and 3 metres due to hard ground. A random selection of 43 samples from all the holes across the dam were selected for ICP analysis in order to determine the base metals present; at what concentrations; and how they vary between the identified major zones i.e. the sulphide and calcine. Gold and silver grades for these samples are currently awaited as they must undergo fire assay analysis. This data will help to determine which processes are required for testing the calcine and sulphide when they are sent for metallurgical analysis and leach tests in Perth, and ultimately the mining processes required. The results in the following table display the suite of base metals present.\nResults from ICP analysis of the tailings dam (weighted averages)\n\n\n\n\n \n\n\nCu (%)\n\n\nCo (%)\n\n\nPb (%)\n\n\nZn (%)\n\n\nAu\n\n\nAg\n\n\n\n\n \nSulphide\n22 samples\n\n\n \n0.33\n\n\n \n0.07\n\n\n \n0.17\n\n\n \n0.76\n\n\n \nawaited\n\n\n \nawaited\n\n\n\n\n \nCalcine\n19 samples\n\n\n \n0.61\n\n\n \n0.05\n\n\n \n0.53\n\n\n \n0.67\n\n\n \nawaited\n\n\n \nawaited\n\n\n\n\n \nOx Zone\n1 sample\n\n\n \n0.48\n\n\n \n0.11\n\n\n \n0.14\n\...
