OceanaGold Unveils High-Grade Drill Results at Haile Gold Mine

OceanaGold Corporation, listed on the TSX and NYSE under the symbol OGC, recently reported encouraging high-grade results from its continual exploration and resource conversion drilling program at the Haile Gold Mine, located in the United States. This announcement, made on May 12, 2026, showcases the company’s commitment to enhancing its resource base and maximizing shareholder value.

Highlights of the Drilling Results

The latest drilling results from the Haile Gold Mine reveal impressive drill intersections that confirm the ongoing potential of the site. The Horseshoe Underground area showcased several notable drilling results including:

• - 15.5 m @ 30.64 g/t Au (UGD0121),
• - 30.5 m @ 13.86 g/t Au (UGD0113),
• - 22.5 m @ 13.42 g/t Au (UGD0122).

Additionally, significant results were recorded in the Ledbetter Underground area, with drill holes yielding:

• - 27.9 m @ 8.60 g/t Au (DDH1313),
• - 27.9 m @ 4.16 g/t Au (DDH1319).

The initial drilling at the Clydesdale site also brought encouraging results, with a notable result of 14.5 m @ 15.81 g/t Au (DDH1305) being highlighted. Gerard Bond, President and CEO of OceanaGold, expressed optimism about the results, underscoring the company’s ability to generate substantial value through effective drilling strategies.

Progress in Resource Conversion

The drilling program not only aims to expand the known reserves but also aims at converting Inferred Resources to Indicated Resources, thereby strengthening the overall resource base. The Horseshoe area has demonstrated excellent continuity of mineralization, and there appears to be significant potential for further development as mineralization remains open in multiple directions.

The latest drilling efforts at the Horseshoe Underground have been designed to focus on resource conversion and expansion across three distinct zones – upper, middle, and lower – with results indicating a solid promise for future growth. The extensively detailed drilling program has seen considerable effort, with over 4,372 meters drilled in the Horseshoe extensions to explore both conversion and expansion opportunities effectively.

Future Exploration Plans

Looking ahead, OceanaGold has set ambitious targets for its exploration program, planning approximately 34,500 meters of drilling for the year 2026, emphasizing both surface and underground opportunities. The company intends to continue focusing on resource conversion at the Horseshoe Underground while testing extensions at the Ledbetter site. Additional drilling efforts will target newly identified areas, such as Clydesdale and Pisces, to explore and delineate substantial mineralization potential.

The exploration strategy takes into consideration the continued refinement of geological models, which enables the systematic identification of new targets that can be explored in the coming years. The Company has demonstrated a commitment to understanding the structural controls of mineralization that will help optimize drilling in the Haile Gold Mine region.

Conclusion

The recent high-grade results released by OceanaGold reaffirm the company’s dedication to exploring and enhancing its mineral resource base at the Haile Gold Mine. With a robust exploration program in place and promising initial results, OceanaGold appears positioned to capitalize on its ongoing endeavors, delivering value to shareholders and solidifying its presence in the mining sector. This continuing success in exploration not only demonstrates the potential for increased mineral reserves but also highlights the significant prospects that lie ahead for OceanaGold in its pursuit of growth and operational excellence.
