Underground mine to complement Haile openpit – OceanaGold

An underground development at gold miner OceanaGold’s Haile gold mine, in South Carolina, could boost the operation’s production by up to 100 000 oz between 2019 and 2025, a preliminary economic assessment (PEA) has shown.
The underground mine will cost $53.1-million to build, it will require life-of-mine capital expenditure of $44.5-million and will be repaid in a three-year period.
