OceanaGold Corp. To Voluntarily Delist From Asx

The Company expects that the Delisting will occur on 31 August 2022. The Company's CHESS depositary interests (CDIs) will be suspended and cease to trade on ASX at the close of trade on 29 August 2022 (being two business days before the Delisting).

Following the Delisting from ASX, the Company's common shares (Shares) will continue to be traded on the Toronto Stock Exchange (TSX) under the trading symbol 'OGC'.

The Company is seeking to delist from ASX due to the ongoing low trading frequency, low volumes traded and limited index inclusion of CDIs traded on ASX as compared to that of the TSX. The CDIs held on the Australian register have declined to approximately 7.5% of the Company's total issued share capital as of 30 June 2022.

The Company believes that the financial, administrative and compliance obligations and costs associated with maintaining the ASX listing are no longer in the best interests of its shareholders as a whole. The delisting is also expected to lead to an increase in the Company's liquidity on the TSX.

ASX has provided its approval for the Company to be removed from the official list of ASX subject to the Company complying with certain conditions. Please refer to the Appendix for the full terms of ASX's approval.

The Company will today send a letter to each CDI Holder (CDI Communication) which sets out, in a form and substance satisfactory to ASX, an overview of the delisting process, as well as the following timetable and options to CDI holders.

The Company is not required to obtain security holder approval for the Delisting.

The proposed timetable for the Delisting is:

All dates and times in this announcement refer to Australian Eastern Standard Time / Australian Eastern Daylight Savings Time (as applicable). These dates and times are indicative only and subject to change. The Company will announce any amendment to those dates and times.

CDI Holders will have the opportunity to:

(a) Convert CDIs into TSX listed Shares

At any time up until the closing date of the Voluntary Sale Facility (7 November 2022), CDI Holders may request to convert their CDIs to the Company's TSX-listed Shares on a 1:1 basis.²

If CDI Holders wish to convert their CDIs into TSX listed Shares on or before the Suspension Date (29 August 2022), they may do so by:

• (for CHESS holders) submitting a request to their sponsoring CHESS participant; or
  
  
• (for issuer sponsored holders) completing a CDI cancellation form and returning this (together with certified identification documentation where required) to the Company's Australian CDI registry, Computershare Investor Services Pty Limited (Computershare).

CDI Holders remaining as at the Delisting Date (31 August 2022) will be sent a personalised request form to allow them to convert their CDIs, if they wish, into TSX listed Shares up until the closing date of the Voluntary Sale Facility.

(b) Sell CDIs on ASX

CDI Holders may sell their CDIs on ASX at any time prior to the close of trading on the Suspension Date (29 August 2022) by contacting their stockbroker or financial advisor who can arrange the sale. After the Suspension Date, CDI Holders will not be able to sell CDIs on ASX.

(c) Participate in the Voluntary Sale Facility

Following Delisting, any remaining CDI Holders will be sent an election form to enable them to elect to participate in a voluntary sale facility (Voluntary Sale Facility), through which their CDIs will be sold in the form of Shares on TSX and the sale proceeds remitted to them in Australian dollars or New Zealand dollars. In addition, individual CDI Holders who would like to receive their proceeds in other currencies will be able to enrol in Global Wire (an international wire payment service provided by Computershare) to receive their proceeds in their local currency.

If a CDI Holder elects to participate in the Voluntary Sale Facility, the Company will arrange, and pay the costs associated with, a broker who will effect the sale of Shares, at the broker's discretion, on behalf of the CDI Holder on TSX. The Company will also pay any costs, levies or fees associated with the sale of Shares on TSX and remittance of sale proceeds in connection with the Voluntary Sale Facility.

(d) Compulsory Sale Process

The ASX Settlement Operating Rules grant CHESS Depositary Nominees Pty Ltd a power of sale over any remaining underlying Shares.

Accordingly, after closure of the Voluntary Sale Facility, the Company will establish a compulsory sale process (Compulsory Sale Process) to facilitate CHESS Depositary Nominees Pty Ltd exercising its power of sale in respect of the underlying Shares held on behalf of any remaining CDI Holders. In other words, the Compulsory Sale Process will operate by default in respect of any remaining CDI Holders who have not requested to become the registered holder of the underlying Shares on the Canadian share register.

To facilitate the Compulsory Sale Process, the Company will appoint a broker who will effect the sale of Shares on behalf of the CDI Holder on TSX and the sale proceeds will be remitted to the CDI Holder in Australian dollars or New Zealand dollars. The Company will pay all brokerage and any related costs, levies or fees associated with the sale of Shares on the TSX in connection with the Compulsory Sale Process.

If the CDI Holder cannot be contacted, the proceeds will be dealt with in accordance with applicable unclaimed money laws.

As noted above, CDI Holders will today be sent a letter which provides further details regarding the options available to them relating to their CDIs and the Delisting process.

A CDI Holder opposed to the Delisting may apply to a court in British Columbia, Canada under the British Columbia Business Corporations Act (BCBCA) on the basis that the Delisting is oppressive or unfairly prejudicial to the CDI Holder, or group of CDI Holders. Under the BCBCA, the court has the power to make any order it considers appropriate, including an order to prohibit the Delisting or to otherwise regulate the affairs of the Company.

The main consequence of the Company's Delisting for CDI Holders is that, from the time the Delisting takes effect, CDIs will no longer be quoted or traded on ASX.

Unless CDI Holders sell their CDIs before Delisting occurs, elect to participate in the Voluntary Sale Facility or request to become the registered holder of the underlying Shares on the Canadian share register, the Shares underlying their CDIs will be sold, by default, pursuant to the Compulsory Sale Process as described above.

If CDI Holders have any questions about the Delisting process, please contact Computershare on 1300 850 505 (within Australia) or +61 3 9415 4000 (outside Australia) between 8.30am and 5.00pm (Australian Eastern Standard Time / Australian Eastern Daylight Savings Time, as applicable).
