AVZ managing director Nigel Ferguson said GRES had done a number of bankable feasibility studies and the firm had an exceptional track record in executing project design and construction developments on time and within budget.
This was on show in the Congo recently when GRES did optimisation studies for Tiger Resources at the Kipoi copper project.
Ferguson said the appointment of GRES as the DFS engineer was a significant milestone for Manono as its work was highly regarded by leading financiers and lending institutions.
