VANCOUVER, Aug. 17, 2026 /CNW/ — OceanaGold Corporation (TSX: OGC) (NYSE: OGC) (“OceanaGold” or the “Company”) is pleased to announce it has entered into a definitive scheme implementation deed (the “SID”) to acquire 100% of the issued shares of Ausgold Limited (ASX: AUC) (“Ausgold”), the owner of the Katanning Gold Project (“Katanning”) in Western Australia, by way of an Australian court-approved scheme of arrangement (the “Scheme” or the “Transaction”).

Under the terms of the Transaction, Ausgold shareholders will receive 0.03365 common shares of OceanaGold for each share of Ausgold held (“Scheme Consideration”). The Scheme Consideration implies a total offer value of A$1.36 per Ausgold share, implying a total transaction equity value of approximately A$776M (US$549M)¹. Ausgold shareholders also have the opportunity to elect to receive the Scheme Consideration value in cash (“Cash Alternative”), subject to scale-back based on a maximum available cash pool for the Transaction of A$194M (US$137M)¹.

Upon completion of the Transaction, it is expected that Ausgold shareholders will own approximately 6% to 8% of OceanaGold. The Ausgold Board has unanimously recommended that Ausgold shareholders vote in favour of the Scheme and intend to vote all shares held by them (approximately 1.4%) in favour of the Scheme. Ausgold major shareholder Dundee Corporation, representing approximately 7.7% of ownership, has also confirmed its intention to vote in favour of the Scheme.²

OceanaGold will hold a conference call on August 17, 2026 at 8 am Eastern Time / 5 am Pacific Time to discuss the Transaction. Dial-in details are provided below.

Gerard Bond, President and Chief Executive Officer of OceanaGold, said:

“The acquisition of Ausgold adds an advanced, high-quality, low-capital, open-pit development asset to our portfolio at an attractive valuation. The Katanning Gold Project will be our fifth asset, located in one of the world’s premier mining jurisdictions and is a natural fit with our proven development and operating capabilities. Our projected free cash flow generation and strong balance sheet give us the ability to fund the development of Katanning, advance our existing growth pipeline including the Waihi North Project, while continuing to deliver meaningful capital returns to shareholders.

“This marks our first acquisition in Australia, and we are excited to build on the great work done by the Ausgold team to further optimize the development of the Katanning Gold Project for the benefit of both OceanaGold and Ausgold shareholders. We look forward to welcoming Ausgold’s shareholders and employees to OceanaGold and working with the stakeholders of the Katanning Gold Project.”

John Dorward, Executive Chairman of Ausgold, said:

“This transaction delivers Ausgold shareholders a compelling upfront premium with the opportunity to retain exposure to the value we expect to unlock at Katanning as part of a larger, diversified and highly cash-generative gold producer. OceanaGold’s financial strength, technical depth and operating track record significantly de-risk the funding and development of Katanning, while our shareholders gain immediate diversification and exposure to a high-quality growth profile which will include Katanning and the world-class Waihi North Project. The Ausgold Board unanimously recommends the OceanaGold proposal and we look forward to working with OceanaGold to complete this transaction and progress Katanning towards production.”

Strategic Rationale and Benefits to OceanaGold Shareholders

The Transaction is expected to deliver significant benefits for OceanaGold shareholders, which includes Ausgold shareholders post-closing:

• Adds a high-quality development asset in a Tier-1 mining jurisdiction: the acquisition of Katanning complements OceanaGold’s existing operations in the USA, New Zealand and the Philippines;
• Enhances OceanaGold’s production and growth pipeline: Katanning is a conventional open-pit development project with +100,000 ounces of annual gold production and 10+ year life potential³, adding meaningful growth to OceanaGold with first gold production expected in 2029⁴;
• Leverages OceanaGold’s development and operating expertise: OceanaGold’s technical, development, permitting and operating capabilities, which includes a technical office in Brisbane and management with significant experience operating in Australia, is expected to enable the full potential of Katanning;
• District-scale exploration upside: Ausgold holds a district-scale landholding of more than 3,000km² across the largely underexplored Katanning greenstone belt, providing the potential for significant longer-term resource growth; 
• Preserves balance sheet strength and financial flexibility: OceanaGold’s strong balance sheet and significant forecast free cash flow generation provide financial flexibility to fund the development of Katanning, advance OceanaGold’s existing growth pipeline and continue to provide meaningful capital returns to shareholders; and
• Accretive acquisition with attractive returns: the Transaction is expected to be accretive to OceanaGold shareholders on a number of key metrics, including net asset value per share, future cash flow per share, and earnings per share, once Katanning achieves commercial production.

Strategic Rationale and Benefits to Ausgold Shareholders

The Transaction delivers a range of compelling benefits to all Ausgold shareholders, including:

• Immediate premium: Provides Ausgold shareholders with immediate and attractive premiums of 28% to the last closing price, and 44% to the 20-day volume weighted average price (“VWAP”) of Ausgold shares for the period up to and including August 14, 2026;
• Tailored consideration mix: Opportunity for Ausgold shareholders to tailor the form of consideration received through the election to receive cash consideration;
• Opportunity to realize upfront value for Katanning: Ausgold shareholders can crystallize certain value now ahead of the upcoming project development, capital investment, and production ramp-up;
• De-risked funding and development: Significantly de-risked funding and development of Katanning by leveraging OceanaGold’s strong balance sheet, cash flow generation, and proven technical and operating expertise;
• Continued exposure to the Katanning Gold Project: Retain exposure to the future development and exploration upside of Katanning through their holding in OceanaGold;
• Diversification via exposure to OceanaGold’s high-quality portfolio and pipeline: Gain exposure to OceanaGold’s global portfolio of four producing assets across the United States of America, New Zealand and the Philippines, along with additional upside in its organic growth pipeline including the world-class Waihi North Project; and
• Enhanced market positioning and liquidity: Increased trading liquidity and access to capital markets as a shareholder in a larger, diversified intermediate gold and copper producer.

Overview of Ausgold

Ausgold is an ASX-listed gold developer with a current market capitalization of approximately A$585M (approximately US$414M)¹. Ausgold is focused on advancing its 100% owned Katanning Gold Project to first gold production.

As of June 30, 2026, Ausgold had A$87M (approximately US$62M)¹ of cash and equivalents, and no debt.

Katanning Gold Project

Katanning is located approximately 275 km southeast of Perth in Western Australia, a Tier-1 mining jurisdiction with well-established infrastructure and access to skilled labour. Ausgold holds granted mining leases over the entire planned development footprint for Katanning and is well advanced through the permitting process⁵.

Ausgold holds a consolidated landholding of more than 3,000 km² across the Katanning greenstone belt. This district-scale tenement package remains largely underexplored.

Ausgold’s Updated Definitive Feasibility Study for Katanning, published in December 2025⁶, outlines a potential conventional open-pit mining operation feeding a 3.6 Mtpa carbon-in-leach processing plant at an estimated total pre-production capital cost of A$355M⁶.

Following implementation of the Scheme, OceanaGold intends to apply its technical, operating, and project development experience to further refine the Katanning development plan, with a focus on optimization initiatives and reducing execution risk. Development activities will focus on additional drilling through 2027 to further delineate mineralization and de-risk operational ramp-up ahead of publishing an updated technical report in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) during 2028, with first gold expected in 2029. OceanaGold will provide an update to the market on its proposed development plan for Katanning at closing of the Transaction.

Key Transaction Terms

Under the terms of the Scheme, Ausgold shareholders will receive 0.03365 OceanaGold shares per 1 Ausgold share, currently valued at A$1.36 per Ausgold share based on OceanaGold’s last closing price of C$39.74 per share and AUD:CAD exchange rate of 0.9833 on August 14, 2026 (the “Scheme Consideration”).

The Scheme Consideration values Ausgold’s fully diluted equity value at approximately A$776M (approximately US$549M)¹.

Ausgold shareholders also have the opportunity to choose to receive the Scheme Consideration in cash (“Cash Alternative”). The proportion of Scheme Consideration ultimately received in cash by those Ausgold shareholders electing for the Cash Alternative will be based on the implied Scheme Consideration value of A$1.36 per Ausgold share and will be subject to the total Cash Alternative elections received and a maximum cash paid as Scheme Consideration of A$194M (approximately US$137M)¹ in aggregate.

Upon completion of the Transaction, and subject to elections received for the Cash Alternative, Ausgold shareholders will own approximately 6% to 8% of OceanaGold.

The Scheme will be effected by way of a court-approved scheme of arrangement under Part 5.1 of the Australian Corporations Act 2001 (Cth), pursuant to which all of the issued share capital of Ausgold as of the Implementation Date (as defined in the SID) will be acquired by OceanaGold, in exchange for the Scheme Consideration. For the Scheme to proceed, a resolution must be approved by at least 75% of all votes cast by Ausgold shareholders and a majority by number of all Ausgold shareholders present and voting (in person or by proxy) at a special meeting called to consider the Scheme (“Scheme Meeting”).

The Scheme is subject to customary closing conditions, including (amongst others) the following customary regulatory approvals: Australian Foreign Investment Review Board and Australian competition approvals; and Toronto Stock Exchange approval for OceanaGold to issue OceanaGold shares as part of the Scheme Consideration.

In connection with the Transaction OceanaGold has agreed to extend an A$20M bridge loan to Ausgold in November 2026 to assist with funding of ordinary course expenditures prior to closing.

Ausgold Board and Major Shareholder Support

The Ausgold Board are supportive of the Transaction and unanimously recommend Ausgold shareholders vote in favour of the Scheme, and intend to vote all Ausgold shares held or controlled by them (approximately 1.4% of Ausgold’s shares on issue) in favour of the Scheme subject to no superior proposal emerging and the independent expert appointed by Ausgold in connection with the Transaction concluding (and continuing to conclude) that the Scheme is in the best interests of Ausgold shareholders.

Subject to those same exceptions, major Ausgold shareholder, Dundee Corporation which holds 42,467,969 Ausgold shares (or approximately 7.7% of Ausgold’s shares on issue), has confirmed its intention to vote all Ausgold shares owned or controlled by it in favour of the Scheme and not dispose of its Ausgold Shares until the earlier of the date of the Scheme Meeting and the date that is 6 months from the date of the voting intention statement.

Estimated Timeline

Full details of the Transaction will be included in Ausgold’s Scheme Booklet, which is expected to be dispatched to Ausgold shareholders in October 2026, with the Scheme Meeting (for Ausgold shareholder approval) expected to be held in late November 2026. If approved by Ausgold shareholders and the Court, and the other conditions are satisfied, the Scheme is expected to be implemented and completed in December 2026.
