Canadian miner Semafo has announced the results of a preliminary economic assessment (PEA) for its Nabanga project, in Burkina Faso, highlighting how the project could be developed with modest initial capital by combining openpit and underground mining operations.
The PEA determines that Nabanga will need to invest $84million to build a mine that will produce 571 000 oz over eight years, at an all-in sustaining cost of $760/oz.
