Note (3): The information in this announcement that relates to the Havieron Feasibility Study (FS) and its outcomes, and the FS Mine Plan Production Target (and the forecast financial information derived from the Production Target) are extracted from Greatland's ASX and AIM announcement "Havieron Project Feasibility Study" dated 1 December 2025. The Company confirms that all material assumptions and technical parameters underpinning the Production Target or forecast financial information derived from the Production Target (as applicable) in that ASX and AIM announcement continue to apply and have not materially changed.

The FS Mine Plan is a production target underpinned by approximately 80% Probable Ore Reserves, 2% Indicated Mineral Resources, 13% Inferred Mineral Resources and 5% Exploration Target (on a contained gold basis over the Life of Mine (LOM)). The Inferred Mineral Resources and Exploration Target included in the FS Mine Plan Production Target are predominantly in the later years of the LOM. Refer to Section 7 of the announcement 'Havieron Project - Feasibility Study' dated 1 December 2025 for further explanation and key assumptions, and the basis for inclusion of Inferred Mineral Resources and Exploration Target in the FS Mine Plan.

Cautionary statement: There is a low level of geological confidence associated with Inferred Mineral Resources and there is no certainty that further exploration work will result in the determination of Indicated Mineral Resources. The potential quantity and grade of an Exploration Target is conceptual in nature; there has been insufficient exploration to determine a Mineral Resource and there is no certainty that further exploration work will result in the determination of Mineral Resources. Accordingly, there is no certainty that the FS Mine Plan Production Target (or the forecast financial information derived from it) will be realised.

Growth, resource development and exploration

· $177.0m invested in growth (Telfer $131.1m, Havieron $29.8m, resource development $16.1m) during the period.

· Completed construction of Tailing Storage Facility 8 Stage 3 expansion lift. 7.3Mt of growth waste stripping of the West Dome Open Pit Stage 7 cutback. 1,712m of growth underground development at Main Dome and West Dome Underground.

· 107,747m of resource growth and conversion drilling as part of Telfer's record 240,000m FY26 drilling program. Telfer Mineral Resource update, including a maiden West Dome Underground Mineral Resource estimate, targeted in the March 2026 quarter.

Funding and risk management

· Entered a binding commitment letter for $500m corporate debt facilities with Tier 1 lending syndicate of ANZ, ING, HSBC, NAB and Westpac (finalisation subject to certain conditions precedent).

· Extended $75m working capital facility maturity to 30 June 2026; facility remains undrawn.

· Continued strategy of downside gold price protection via put options while retaining full upside exposure (225,004oz from January 2026 to June 2027; weighted average strike $4,500/oz).

Greatland Managing Director, Shaun Day, commented: "Our half-year result reflects excellent operating and financial performance at Telfer through the period, underpinned by disciplined cost control and full upside exposure to a strong metal price environment, resulting in substantial cash generation and profitability.

"With the Havieron Feasibility Study completed during the period, our priorities now are continued operational execution at Telfer, demonstration of the mine life extension opportunities at Telfer, and development of Havieron to deliver a world-class integrated Havieron and Telfer operation.

"Our robust financial position, with closing net cash of $948 million and a $500 million debt commitment, positions us strongly to deliver our exceptional growth profile."
