Permit for Haile Gold Mine Expansion
First ore from the Haile underground on-track for the fourth quarter of 2023
(VANCOUVER B.C.) OceanaGold Corporation (TSX: OGC) (“OceanaGold” or the “Company”) is pleased to
announce that the United States Army Corp s of Engineers (“ ACOE”) has issued the Supplementary
Environmental Impact Statement Record of Decision (“SEIS ROD”) for the expansion of the Haile Gold Mine
(“Haile”) located in Kershaw, South Carolina.
In addition, the South Carolina Department of Health and Environmental Control (“DHEC”) issued the Mine
Operating Permit (“MOP”) on December 14, 2022, which, following a statutory 15-day period, will become
final and will complete the state permitting process for the Haile expansion.
OceanaGold President and CEO, Gerard Bond, said “The receipt of the Haile SEIS ROD and the MOP
represents a significant milestone for OceanaGold, putting the Company on a clear path to deliver increased
gold production and lower unit costs at this cornerstone asset. We are thrilled to be progressing the next
stage of Haile’s growth as we expand our operations underground and , with exploration success, pursue
further opportunities to profitably extend the mine life.”
The receipt of the SEIS ROD and t he MOP allows for development and operation of the underground mine
and an expansion of the operating footprint to allow for additional waste containment facilities and expanded
tailings storage capacity.
With the early works program approved in the third quarter, underground development of the main production
decline and exhaust ventilation portals is safely progressing in -line with plan. First ore from the Haile
underground remains on-track for delivery in the fourth quarter of 2023.
