Regis Resources Details Gold Asset Strategy and Exploration Plans at Noosa Mining Conference 2026

Regis Resources’ Operational Portfolio and Asset Overview

Regis Resources Limited functions as an Australian gold exploration and mining entity with a diverse portfolio spanning key projects such as Duketon and a 30% ownership interest in the Tropicana operation. These assets underpin the company’s production and exploration efforts throughout Western Australia. Regis’ business model focuses on exploration, development, and gold extraction, with management actively evaluating the economic feasibility and operational potential of each project.

The Duketon project serves as a core asset for Regis, with probable ore reserves prepared in line with the Joint Ore Reserves Committee (JORC) Code. These reserves, validated by competent persons, form the basis for medium-term production planning and capital allocation. Although Regis holds a minority interest in Tropicana, this asset remains a significant contributor to cash flow and strategic value. The company utilizes both external technical consultants and internal geological teams to ensure resource and reserve estimates remain accurate and up-to-date, maintaining transparent communications with stakeholders.

Ben Hur Underground Exploration Target Progress

Regis Resources has identified an underground exploration target at Ben Hur, part of its broader exploration pipeline. As of the company update dated 21 November 2024, this target is estimated to contain between 4.0 million and 6.0 million tonnes of material grading 2.2 to 2.8 grams per tonne gold. The target represents potential down plunge extensions of existing open pit mineralisation, spanning a vertical range from 400 metres relative level down to minus 100 metres, offering 500 metres of vertical exploration potential. This target underscores Regis’ commitment to expanding its resource base beyond current reserves.

Prepared according to the JORC Code 2012, the Ben Hur exploration target is based on a thorough review of geological data, including drill hole records, geophysical surveys, and prior mineral resource estimates. Regis emphasizes that this target is conceptual, with ongoing drilling designed to test and potentially upgrade parts of the target to mineral resource status. The company notes that insufficient exploration has been conducted to classify the entire target area as a mineral resource, and it remains uncertain if further drilling will result in resource estimation. This methodical exploration approach aligns with industry standards and informs capital allocation and operational priorities.

Mineral Resources and Ore Reserves Reporting Standards

Regis Resources adheres to Australian reporting standards for its mineral resource and ore reserve statements, which differ notably from United States Securities and Exchange Commission requirements. The latest mineral resource and ore reserve disclosures were released to the ASX on 22 April 2026 and 19 June 2026, with exploration updates on 26 June 2026. These statements, prepared by competent persons in accordance with the JORC Code, reflect the company’s technical position as of the respective dates. Regis has secured competent person consents for these releases, which remain valid for subsequent disclosures unless formally withdrawn or superseded.

The company confirms no new information has materially impacted these disclosures, and all material assumptions and technical parameters remain unchanged. This assurance is vital for investors assessing the reliability of Regis’ resource and reserve figures. It is important to note that Australian standards differ from international reporting frameworks, so investors should consider these differences when comparing reports across jurisdictions.

Technical Expertise and Competent Person Oversight

Robert Barr, a full-time Regis Resources employee and member of the Australasian Institute of Mining and Metallurgy (AusIMM Member #991808), serves as the competent person responsible for mineral resource estimates and exploration targets. Possessing extensive experience relevant to the company’s mineralisation style and deposit types, Mr Barr’s role complies with JORC Code 2012 requirements. His formal consent has been provided for the inclusion of his information in company reports.

Regis maintains robust technical governance through detailed drill hole databases, geophysical data, and mineral resource models to continually refine resource and reserve estimates. The company employs block model estimation and grade-tonnage relationships derived from drilling data, ensuring quantitative rigor in resource definition. Mr Barr’s responsibilities extend to ongoing validation of assumptions, guaranteeing that publicly disclosed data remains accurate over time.

Forward-Looking Statements and Associated Risks

Regis Resources’ company update contains forward-looking statements subject to risks inherent in gold exploration, mining, and production. While deemed reasonable based on information available at the presentation date, actual outcomes may differ materially due to known and unknown risks beyond the company’s control. These include commodity price volatility, foreign exchange fluctuations, economic conditions, rising input costs, exploration uncertainties, and licensing challenges.

Additional risks encompass potential declines in reserve grades or quantities, political and social factors, regulatory changes, environmental events such as extreme weather, and workforce-related challenges including recruitment, retention, industrial relations, and litigation. Regis does not guarantee returns, capital repayment, or tax outcomes. Investors are advised to seek independent counsel and should not rely on historical data as indicators of future performance or share price movements.

Duketon Project’s Probable Ore Reserve Details

The Duketon project is a key element of Regis Resources’ reserve base, with probable ore reserves prepared under the JORC Code. These reserves reflect a reasonable expectation of economic extractability, offering greater geological certainty than exploration resources but less than proven reserves. This classification informs investors about the risk profile and potential of future production.

Regis does not provide a production target for Tropicana, reflecting its minority ownership and differing development status compared to Duketon. Reserve estimation is iterative, with updates driven by exploration results, commodity price changes, and cost assumptions. Regular resource and reserve updates enable investors to monitor progress and evaluate exploration effectiveness.

Governance and Disclosure Practices at Regis Resources

Regis Resources operates within a governance framework ensuring accurate, timely, and compliant disclosure under ASX listing rules and Australian securities laws. The company confirms that competent person findings remain consistent in form and context across communications, maintaining transparency and preventing misleading interpretations. Detailed audit trails link technical data to responsible competent persons.

Past performance and pro forma financial data, including resource and reserve upgrades, are provided for illustration only and should not be viewed as forecasts of future results. Mining and exploration carry inherent uncertainties, and technical discoveries may occur unpredictably. Investors should exercise caution with forward-looking statements and seek professional advice before investing. Regis does not commit to updating forward-looking statements except as required by law.

Tropicana Operation and Minority Ownership Implications

Regis Resources holds a 30% interest in the Tropicana operation, a valuable asset despite the minority position. This stake offers exposure to gold production cash flows and asset appreciation without full capital funding responsibilities. The joint venture structure enables Regis to focus capital on exploration at other projects while benefiting financially from Tropicana.

The minority ownership impacts financial reporting and investor interpretation, as operational control and decision-making at Tropicana are limited. Performance depends on joint venture partners’ management and operational effectiveness, factors partially outside Regis’ direct influence. Investors should monitor Tropicana developments via company announcements and joint venture partner communications.
