Integrating the Gonka deposit into its Yanfolila gold project, in Mali, will result in a significant uplift in the project’s net present value (NPV), says Aim-listed gold miner Hummingbird Resources. The miner on Tuesday reported that a recently completed desktop study on the Gonka deposit, 5 km from Yafolila, had shown that 92 000 oz could be mined at 2.3 g/t in an openpit operation and 77 000 oz at 4.5 g/t in an underground operation over a six-year mine life.
