Bulk concentrate cyanide leach testwork showed that a gold recovery of 54.8% was achievable at a particle size of 80% passing 10µm.A bulk sulphide float recovered 85% of the gold and 83% of the silver to a rougher concentrate assaying 2.98 g/t Au and 94.9 g/t Ag, respectively.Rougher flotation optimisation found that 81.2% and 75.7% of gold and silver were recoverable to a concentrate, at grades of 3.41 g/t gold and 84.8 g/t Ag silver, and at a high mass pull of 25.5% by weight.Metal recoveries of 47.1% and 26.1% were also obtained for silver and copper, respectively Whole ore cyanide leach testwork showed that 49.8% of the gold was recoverable by cyanide leaching.The composite sample was prepared from selected diamond drill half core intervals and RC percussion drill chips A single bulk composite sample representative of the sulphide mineralisation at Hamama West underwent metallurgical testwork including cyanidation leach testing and flotation testwork to assess its amenability to cyanide leaching, and the potential to produce a saleable gold- or gold-silver bearing concentrate.Both the copper and zinc concentrates contain reasonable gold and silver credits Sequential flotation tests carried out on the Rodruin sulphide mineralisation types indicate that potentially saleable copper and zinc concentrates can be achieved at reasonable metal recoveries and grades.Results from a locked cycle flotation test carried out on sample ROMS-007 produced a copper concentrate of 28.1% copper at a recovery of 69.2%, and a zinc concentrate of 61.6% zinc at a recovery of 79.6%.The composite samples were prepared from selected diamond drill half core intervals Two composite samples representing the main sulphide mineralisation types at Rodruin underwent preliminary metallurgical testwork investigating the potential to produce saleable copper and zinc concentrates.Rodruin and Hamama West are both located within the Company’s 100% owned Abu Marawat Concession (“Abu Marawat” or the “Concession”), in the Eastern Desert of Egypt. update investors on the results of further preliminary metallurgical testwork from its Rodruin and Hamama West projects.
