What else do investors need to know?
Exploration at Tropicana in 2025 focused on both expanding known mineralisation and identifying new underground targets. Drilling increased confidence in down-plunge extensions and uncovered new areas to support upcoming resource definition.
Underground resource classifications improved, with Measured and Indicated Mineral Resources increasing to 2.5Moz from 2.2Moz, demonstrating ongoing replacement of mined ounces and supporting future project life.
The Tropicana JV’s work through the year has established a strong pipeline of underground growth projects, with further drilling planned to test high-priority zones like Boston Shaker, Havana, and the Cobbler conceptual target.
What did Regis Resources management say?
Chief Executive Officer and Managing Director Jim Beyer said:
It is very pleasing to see the Ore Reserves and Mineral Resources at Tropicana continue to grow and extend the mine life in line with our expectations. The ongoing, year on year growth delivered by the team is an excellent result for our shareholders and clearly continues the trend of underground Ore Reserves growth exceeding depletion. Impressively, before depletion, Ore Reserves within the undergrounds at Tropicana have grown by over 500k ounces of gold since 2021.
What’s next for Regis Resources?
Ongoing drilling at Tropicana is expected to further define and extend underground reserves, with several high-priority areas identified for exploration. Management remains confident that these initiatives will underpin the mine’s ability to generate strong cash flows well into the next decade.
The company continues to focus on replacing mined ounces each year, aiming to maintain a long mine life and robust resource base. Developments at Tropicana should support Regis Resources’ long-term growth strategy and deliver ongoing value for shareholders.
