Orvana tailings reprocessing at EMIPA BoliviaAt one point Orvana suggested the company would consider reprocessing the tailings at their EMIPA/Bolivian operation, to extend the life of the milling operation, once they completed processing the oxide stockpile. Has anyone seen an estimate of the tonnes of tailing that could be treated, the Au/Cu/Zn/Ag grade of the tailings and what sort of percent recovery would be possible, on reprocessing the tailings?
