Tiger Resources says latest leach tests at Kipoi signal higher copper recovery rates and low costs
Tiger Resources Limited (ASX; TSX: TGS) has reported positive results from leach tests at its Kipoi copper project in the Republic of Congo, saying it validated earlier leach test work results, signalling potentially high levels of copper recovery and low operating costs.
Leach kinetics were fast with high recovery of acid soluble copper being greater than 96% with majority of leaching completed in four hours, while gangue acid consumption was very low at less than 10 kg/t (kilograms per tonne), generally in the range of 4.5 to 6.4 kg/t.
The results did not offer any indication of adverse leach kinetics with coarser grind sizes, also suggesting that ore would be amenable to agitation or heap leaching or combination of the two.
The test work was a part of Stage Two feasibility work to determine the suitability of oxidised copper ore from the Kipoi project to be treated by leach solvent extraction electrowinning (SX/EW) processing to produce cathode copper, forming Stage Two of the planned development at Kipoi, which is targeting completion of construction of a 25,000 tpa (tonnes per annum) SCEW plant to produce cathode copper by late 2013.
The expanding resource at Kipoi could potentially support a 100,000 tpa SXEW production capacity, the company said in the statement.
The findings of the latest test work are consistent with conclusions made in earlier reports as results of all three studies showed that all mineralised lithology types at Kipoi Central had a high percentage of above 96% of readily leachable copper with low to moderate GAC, which Tiger Resources said was “very encouraging.”
