Gold miner Caledonia Mining Corporation has confirmed that it will develop the Bilboes sulphide gold project, in Zimbabwe, in a single phase instead of multiple phases as initially planned, and with a revised approach to the tailings storage facility (TSF).

In a preliminary economic assessment (PEA) published on May 30, Caledonia and consultancy DRA Projects finds that the TSF will be built on a modular basis to reduce initial capital expenditure and improve economic returns; however, this revised approach constitutes a significant change to the project.
