OceanaGold Reports Mineral Reserves and Resources for the Year Ended 2025

OceanaGold Corporation, headquartered in Vancouver, is proud to announce its latest findings on mineral reserves and resources for the year concluding on December 31, 2025. The company, which operates in the gold and copper industries, has demonstrated considerable advancement through effective exploration initiatives during 2025, particularly highlighted at its Horseshoe Underground and Wharekirauponga projects.

Key Highlights

• - Total Mineral Reserves: The company reported a total of 5.83 million ounces of gold across its four operating assets. This reflects a careful balance between mining efforts and resource conservation.
• - Measured and Indicated Resources: The findings include 8.63 million ounces of gold, with inferred resources amounting to 2.5 million ounces.
• - Project Changes: An initial underground mineral reserve of 0.44 million ounces of gold at the Ledbetter Underground has been designated, following strategic shifts in mining methods. This move aims to enhance net present value (NPV) and reduce operational costs by transitioning to underground mining.
• - Profitability Considerations: The project has reassessed future gold price assumptions, positioning them at a responsible $2,200 per ounce for reserves, while resources have been placed at $2,450 per ounce.

These updates demonstrate OceanaGold's ability to adjust operations according to market conditions, thus extending the mine life at Macraes to 2032. The expansion is further supported by a higher gold price environment, enhancing the economic viability of previously marginal open-pit mining operations.

Exploration and Resource Growth

Promising results at the Havila area of the Haile Gold Mine further boost investor confidence. The technical plans for Haile and Macraes will be published through updated NI 43-101 Technical Reports by March 31, 2026. The Didipio Technical Report is projected to be released in the first half of 2026. According to Gerard Bond, the President and CEO of OceanaGold, the company's exploration investments will see a significant increase of 50%, with a dedicated expenditure of $60 million in 2026.

Sustainable Mining Practices

The shift at Haile from open pit to underground mining focuses not just on profitability but efficiency as well. The revised method is expected to generate less waste and contribute to lower greenhouse gas emissions, aligning with global sustainability goals.

Moreover, the transition extends the mine's operational life to 2036, allowing for an average production of around 210,000 ounces of gold annually from 2027 through 2031. The move also reflects a commitment to environmental social governance (ESG) practices.

Looking Forward

OceanaGold’s strategy remains centered on maximizing free cash flow, ensuring responsible operations that benefit shareholders while also addressing environmental implications. The company’s commitment to exploration and resource management is a testament to its intention to navigate the changing dynamics of the global mining market successfully.

In conclusion, OceanaGold’s latest report not only underscores the current successes but also sets a promising foundation for future growth and sustainability in the resource mining sector. As updated mine plans roll out and exploration efforts multiply, stakeholders can expect robust developments in the company’s operational efficiency and resource conservancy in years to come.
