Ghana is considering three bids from local investors to take over Gold Fields' Damang gold mine, which requires up to $1 billion of investment to revive. The move comes a year after the government took control of the asset, following the company's failure to declare verifiable reserves. Mining contractors Engineers & Planners (E&P) and BCM International, and consortium Vortex Resources have applied to own the mine. A decision is expected as soon as possible.
