OCEANAGOLD TO LIST ON THE NEW YORK STOCK EXCHANGE ON APRIL 7, 2026

The New York Stock Exchange has approved the application to list Oceanagold Corp.'s common shares. Oceanagold expects that the common shares will commence trading on the NYSE at the market open on Tuesday, April 7, 2026, under the ticker symbol OGC. Following the NYSE listing, quotation on the U.S. OTC Markets will be discontinued. The company's common shares will continue to trade in Canadian dollars on the Toronto Stock Exchange under the same ticker symbol, OGC. Shareholders are not required to take any action.

Oceanagold representatives will participate in the opening bell ceremony on the trading floor of the NYSE on Tuesday, April 7, 2026. A video of the bell-ringing ceremony will be available on the NYSE website and the replay will be available on the company's website.

Gerard Bond, president and chief executive officer of Oceanagold, said: "This is a significant milestone for Oceanagold. Listing on the NYSE expands our access to investors in the United States, enhances trading liquidity, and better reflects the scale and geographic presence of our business.

"Our Haile gold mine in South Carolina, USA, representing nearly half of our gold production (1) in 2026, is the primary driver of the company's near-term production growth and is one of the largest gold mines in the USA. With record financial performance delivered last year, production growth in 2026 and our focus on shareholder value creation, the NYSE listing provides the opportunity for more investors to participate in the company's success."

(1). At the midpoint of guidance, Haile represents approximately 45 per cent of gold production in 2026. Please see the Q4 (fourth quarter) 2025 MD&A (management's discussion and analysis) for further details.
