OceanaGold announces publication of the Haile Supplementary environmental impact statement

The SEIS is now in a 30-day public comment period, after which there is a 15-day review period before the final SEIS Record of Decision (“ROD”) is then scheduled to be issued. The Company is of the view that the comment period and the review period are unlikely to result in a change to the SEIS. The Company anticipates the South Carolina Department of Health and Environmental Control and ACOE will issue the associated permits shortly after the ROD is finalized and their permit process is complete.

The ROD and related permits are required to commence development of the Haile underground mine and to expand the operating footprint to allow for additional potentially-acid-generating waste containment facilities, overburden facilities and expanded tailings storage facility.

Gerard Bond, President and CEO of OceanaGold, stated “The publishing of the SEIS is an important step towards finalizing this process and receiving the related operating permits that will allow commencement of the development of the underground mine, increase Haile’s gold production and help unlock the full value of Haile.”

Authorized for release to the market by Company Secretary, Liang Tang.
