ASX Announcement

DECEMBER QUARTER DEMONSTRATES OPERATIONAL STRENGTH, DELIVERS RECORD CASH GENERATION AND CONFIRMS GROWTH OPTIONALITY

OPERATIONS

• Lost Time Injury Frequency Rate (LTIFR 12MMA) was 0.34 per million hours.

• Gold production of 96.6koz at an AISC of $2,839/oz (incl $179/oz of non-cash stockpile drawdown cost).

• Duketon: 57.6koz gold produced at an AISC of $3,151/oz.

• Tropicana: 39.0koz gold produced at an AISC of $2,303/oz.

FINANCIAL AND CORPORATE

• Gold sales for the quarter of 99.5koz totalled $641M at an average realised price of $6,436/oz.

• Operating cash flow for the quarter of $419M: Duketon: $231M and Tropicana: $188M.

• Paid a fully franked dividend of 5c per share.

• Cash and bullion as at 31 December 2025 was $930M , increasing over the quarter by a record $255M, after the payment of $38M in dividends, investing $115M on capital expenditure and $5M on McPhillamys.

GROWTH

• Announced the development of 251koz Ore Reserves at Buckingham–Wellington open pit within Duketon North, expected to be mined over 6 years at strong forecast financial returns.

• Drilling across Garden Well Underground, Beamish South, Rosemont Stage 3, Ben Hur and Tropicana continues to extend mineralisation and support a substantial pipeline of organic growth opportunities.

MCPHILLAMYS

• The Federal Court heard the Section 10 judicial review application and a decision is pending.

• Progressed parallel study work on a technically feasible integrated waste landform concept incorporating co-disposal within the planned waste dump.

Regis Resources’ (ASX: RRL, “Regis” or “the Company”) Managing Director, Jim Beyer, said: “The December quarter saw another consistent and reliable operational performance across Duketon and Tropicana, translating into record cash and bullion generation and continued strengthening of the balance sheet.

Our teams delivered safely, producing 96.6koz at an AISC of $2,839/oz, while maintaining cost discipline and progressing key underground development and exploration programs across the portfolio. Further to this, the addition of the Buckingham-Wellington pit to our production outlook means our Duketon North Operation will now continue to produce gold through to the end of FY31.

Importantly, the strength of our operating performance and balance sheet supported the recommencement of fully franked dividend payments, with $38 million returned to shareholders during the period. This return reflects our prudent approach to capital management, as we continue to invest in value-accretive growth and maintain financial flexibility. We expect to release a formal capital management policy in conjunction with our half year results in February.”

FINANCE AND CORPORATE

Cash and Bullion Position and Gold Sales

Gold sales for the quarter were 99.5koz at an average price of $6,436/oz for sale receipts of $641M.

Operating cash flow totalled $419M, comprising $231M from Duketon and $188M from Tropicana.

Capital expenditure was $115M with major items including:

• At Duketon, $58M in development, pre-production and deferred waste costs (of which $27M relates to Garden Well Main and Rosemont Stage 3 growth capital), and $14M in plant and equipment; and

• • At Tropicana, $15M in development, pre-production and deferred waste costs, $2M pre-production costs at the Havana Underground mine, and $7M on plant and equipment; and

• $19M for exploration.

Additionally, there was $5M of expenditure associated with McPhillamys. As a result of the Section 10 declaration all McPhillamys’ costs are expensed through the Profit and Loss account.

With the strong financial performance recorded for FY25, a fully franked dividend of 5 cents per share was declared, totalling $38M, paid on 6 October 2025. The growth in Regis’ cash and bullion for the quarter is presented in Figure 2.

Capital Management Policy

With our long history of dividend payments ($585m since 2013), Regis is committed to returning prudent amounts of capital to shareholders by way of dividends and/or share buy backs. To this end, as discussed in our FY25 Annual General Meeting, our intention is to publish a formal capital management policy. We expect this to be released in conjunction with our half year results in February.

GROWTH

– Buckingham Wellington Open Pit

As announced[1] , Regis released an update on the Buckingham–Wellington Open Pit ( BuckWell ). This highlighted the outcomes of detailed geological reinterpretation and an updated trade-off study that expanded the BuckWell Probable Ore Reserves to 251koz from 128koz. The updated mine plan is expected to deliver approximately 223koz of recovered gold over six years, with ore fed through the Moolart Well mill, at Duketon North, once low-grade stockpile processing concludes in late FY26. First ore is scheduled for late FY26, with steady-state build-up of production expected in FY27 and consistent production through FY31.

BuckWell is a strategic, near-term opportunity that leverages existing infrastructure, approvals and milling capacity. It provides a capital-efficient pathway to maintain throughput, convert spare capacity into incremental cash flow, and preserve long-term optionality across the broader Duketon operations. Under November 2025 broker consensus gold price assumptions, which assume a weighted average gold price of A$5,387/oz, the plan delivers strong financial outcomes, including pre-tax cash flow of $336 million, a pre-tax NPV5.6% of $268 million, an IRR of 127% and a ~21-month payback period.

Importantly, the staged nature of the development provides flexibility in sequencing and timing, enabling Regis to adjust the pace and extent of mining to reflect prevailing gold prices. This allows the Company to advance profitable ounces in a higher-price environment while retaining discretion to defer later stages if required. The plan is consistent with Regis’ disciplined capital management approach and demonstrates the ability to respond decisively to favourable market conditions.

Bi-Annual Exploration Update

During the quarter, Regis released its Bi-Annual Exploration Update[2] . The update outlined the depth of the Company’s exploration pipeline, with more than 100 prospects and projects at varying stages of maturity being actively evaluated.

Exploration activities continued to deliver positive results across the portfolio, with drilling programs consistently identifying extensions to mineralisation and supporting the ongoing assessment of near-mine and regional growth opportunities. Key outcomes for the quarter included:

• Continued confirmation of mineralisation outside current mine designs at Garden Well Underground, supporting the assessment of deeper down-plunge extensions.

• Drilling at Rosemont Stage 3 Underground intersected multiple high-grade zones, extending mineralisation approximately 300 metres south of existing designs and strengthening mediumterm underground growth potential.

• Ben Hur returned consistent high-grade intersections and the down-plunge continuity of the South Lode was further defined.

• Strong geological results at Beamish South, demonstrated similarities to Garden Well and highlighting potential for both open pit and underground development pathways.

• Underground drilling at Tropicana delivered strong infill and extensional results to the south and down dip of existing mining areas, outlining potential additions to both the Indicated and Inferred Mineral Resource categories.

• Further encouraging results from drilling across Tropicana continues to support the life extending strategy of targeting underground extensions, including the Havana offset zone.

These outcomes reinforce the quality of Regis’ asset base and support the acceleration of works. With these extremely encouraging results, exploration expenditure for FY26 has been increased by circa $20M and is now expected to be between $70M and $80M.

MCPHILLAMYS

As announced on 7 November 2024[3] , Regis commenced formal legal proceedings in the Federal Court in respect of the former Federal Minister for Environment and Water, the Hon. Tanya Plibersek MP’s declaration of protection over part of the approved McPhillamys Gold Project.

The judicial review of the Section 10 declaration under the Aboriginal and Torres Strait Islander Heritage Protection Act 1984 (Cth) was heard by the Federal Court from 10 to 12 December 2025, and judgment is currently reserved.

Regis continues to progress a dual-track strategy to return McPhillamys to an approvable status. In parallel with the court process, work has advanced on assessing the suitability of an Integrated Waste Landform (“IWL”) incorporating a form of co-disposal within the planned waste dump.

Initial study outcomes indicate that the concept is technically feasible, and further detailed engineering, environmental and commercial assessments are underway to progress facility design, approvals pathway and potential development timeframes.

Regis will provide a further update once the Federal Court has handed down its decision and the IWL study work has progressed.

FY26 GUIDANCE

FY26 production and cost guidance remains unchanged, with the increase to guided exploration expenditure driven by extremely encouraging results discussed above (see Table 4).
