OCEANAGOLD FILES ANNUAL INFORMATION FORM AND UPDATED TECHNICAL REPORTS FOR HAILE, MACRAES AND DIDIPIO

Oceanagold Corp. has filed its annual information form, along with updated technical reports prepared in accordance with National Instrument 43-101 -- Standards of Disclosure for Mineral Projects for three of its operations -- Haile, Macraes and Didipio, each with an effective date of Dec. 31, 2025.

The projected gold production and cost profile outlined in the technical reports positions the company to continue to generate substantial free cash flow at current gold prices. The mine plans set forth in the technical reports are based on the company's 2025 mineral reserves only (estimate using a price of $2,200 per ounce gold) and do not include inferred mineral resources or exploration upside. Mineral reserves and resources estimates utilized in the technical reports were released in the company's Feb. 18 news release titled "Oceanagold Reports Mineral Reserves and Resources for the Year Ended 2025." The company's 2026 guidance, outlined in the fourth quarter, and full year 2025 management's discussion and analysis released Feb. 18, 2026, remains unchanged.

The technical reports and annual information form are available under the company's profile on SEDAR+ and on the company's website.
