Regis Drills High-Grade Extensions at Rosemont and Garden Well Underground

Exploration Momentum at Duketon and Tropicana

Regis Resources (ASX, RRL) has delivered a comprehensive biannual exploration update, spotlighting encouraging progress across its Duketon and Tropicana gold operations. The company’s methodical drilling campaigns have reinforced geological confidence and unveiled promising extensions to mineralisation, vital for sustaining long-term mine life and supporting future resource upgrades.

With a substantial pipeline exceeding 100 prospects at various maturity stages, Regis is actively advancing both underground and open pit targets. This breadth of opportunities reflects a strategic commitment to exploration that underpins the company’s growth trajectory.

Key Highlights from Duketon

At Duketon, the Garden Well Underground remains a focal point, where drilling has confirmed the continuity of mineralisation beyond current mine designs. The Exploration Target here suggests a potential 0.8 to 1.3 million ounces of gold, with recent intersections validating the scale and grade of the system. Notably, infill and extensional drilling are underway to upgrade resource categories and refine mine planning.

Nearby, Beamish South has emerged as a compelling target, sharing geological characteristics with Garden Well. Drilling results indicate both shallow open pit mineralisation and the potential for deeper, high-grade underground shoots, expanding the scope for future development.

Further south along the Banyego-Rosemont Trend, Rosemont Stage 3 Underground drilling has intersected multiple high-grade zones extending approximately 300 meters beyond existing designs. These findings bolster medium-term growth prospects, with underground development planned to facilitate more efficient resource definition.

Ben Hur continues to be a promising area, with drilling confirming consistent high-grade intersections and down-plunge continuity of the South Lode. The Exploration Target here, ranging from 300,000 to 550,000 ounces, could establish a new underground production source within the Duketon Belt.

Tropicana’s Underground Potential

At Tropicana, underground drilling has focused on infilling and extending mineralisation within a structurally defined corridor. The Tropicana Underground program has yielded strong intercepts, enhancing the Indicated and Inferred Mineral Resource base. Encouraging results from Havana Underground Offset and Boston Shaker Underground further support continuity at depth, with ongoing drilling aimed at resource conversion and expansion.

These exploration successes at Tropicana complement Regis’ broader portfolio, reinforcing the joint venture’s position as a significant contributor to future production.

Strategic Outlook

Regis’ Managing Director and CEO, Jim Beyer, emphasised the value of the systematic exploration approach, noting that the steady flow of opportunities is critical for sustaining future studies, reserve conversions, and mine life planning. The company’s ongoing drilling programs into FY26 signal a robust pipeline that could underpin growth and operational resilience.

While the Exploration Targets remain conceptual and subject to further validation, the consistent high-grade intersections and geological continuity provide a strong foundation for optimism. Investors and analysts will be watching closely as Regis advances its drilling and resource definition efforts.
