Greatland Resources Limited | September 2026 Quarterly Activities Report 2 ▪ The Telfer geology team completed a total of 51km of growth and 22km of conversion drilling for the quarter, with six underground, three reverse circulation and three surface diamond drill rigs in operation. An additional surface diamond drill rig has been approved for the Pinnacles Prospect to continue testing of the highly prospective extension to the West Dome geological structure and stratigraphy. Greatland Managing Director, Shaun Day, commented: “We are pleased to have started the 2027 financial year with a well-executed operational performance and good cost control in the first quarter, which included successful completion of the year’s major planned maintenance of the process plant. “During the quarter, we achieved excellent process plant throughput, improved open pit productivity, increased underground ore output and record copper recoveries which culminated in both gold production and AISC performing better than plan. “Greatland completed the quarter with a closing cash balance of $1,314 million and no drawn debt. An increase in cash build was achieved, notwithstanding significant investment in Telfer and Havieron growth capex, the ongoing surge in exploration and elevated tax payments. This balance sheet strength provides a robust platform to deliver our organic growth objectives through the development of Havieron and ongoing investment to grow and extend Telfer. “We are particularly pleased to have commenced the construction stage of our world-class Havieron project, while continuing to make good progress at Telfer’s high-grade West Dome Underground. The investments we make in FY27 will lay the foundations for a period of sustained production growth towards a higher-quality, longer-life gold-copper production centre at an integrated Telfer-Haverion.” Conference Call Greatland will present the Quarterly Activities Report via a webcast for shareholders, research analysts, media and other interested stakeholders on Monday, 26 October 2026 at 7:30am AWST / 10:30am AEDT (11:30pm GMT on Sunday, 25 October 2026), followed by a Q&A session.

Greatland Resources Limited | September 2026 Quarterly Activities Report 3 Overview Greatland Resources Limited ( Greatland) is pleased to report operating (unaudited) results for the 3-month period from 1 July 2026 to 30 September 2026 (September quarter). Greatland produced 70,131oz Au and 2,927t Cu at an AISC of $2,925/oz Au in the September quarter, with both metrics better than plan primarily due to strong processing throughput. Greatland remains on track for FY27 full year production guidance of 260,000 – 300,000oz Au at an AISC of $2,900 – $3,330/oz Au. As previously outlined, production is anticipated to be modestly second half weighted due to open pit scheduling, and the successfully completed major planned 15-day process plant maintenance shut in the September quarter.

Mining Open Pit Open pit ore mined during the September quarter was from Stage 2, Stage 7 and Stage 8 (refer Figure 1), totalling 4.05Mt at 0.45g/t Au and 0.04% Cu. Dump leach ore mined was 0.17Mt. Total material mined (TMM) was 7.86Mt including approximately 3.64Mt of waste. This is the seventh consecutive quarter-on-quarter increase in TMM, driven by a combination of higher trucking availability from new and rebuilt haul trucks matched with consistent digger productivity, and ongoing focus to improve bench turnover and open up larger, more productive work fronts in Stage 7.
Page 5
Greatland Resources Limited | September 2026 Quarterly Activities Report 5 Strip ratio (waste:ore) for the Stage 7 development during the quarter was 1.7, down from 2.3 in the previous quarter as more ore is exposed. Total Stage 7 waste mined in the quarter was 2.82Mt for a total cumulative waste mined of 19.02Mt to the end of the September quarter. Strip ratio for Stage 7 is expected to average 1.4 – 1.5 for FY27. Underground Ore mined during the September quarter was predominantly from A-reef and the Eastern Stockwork Corridor (ESC) areas of the Main Dome Underground (MDU) (refer Figure 1), totalling 0.38Mt at 1.33g/t Au and 0.32% Cu. Reduced copper grade compared to prior quarters was due to completion of the first stage of the higher-grade Rey mining area. Record development metres were achieved for the seventh consecutive quarter and totalled 2,021m, with 674m growth capital development including ongoing extension opportunities at West Dome Underground (WDU) and ESC. The second development drive from the MDU to the WDU progressed during the September quarter and subsequently broke through in early-October, extending the primary ventilation loop to the current drill platform location. The shaft access haulage drive development is progressing from the shaft and crusher end to connect the existing shaft and return air rises to the WDU mining area. Figure 1: September quarter mining areas Processing The September quarter delivered processed tonnes of 4.89Mt with an average head grade of 0.50g/t Au and 0.07% Cu. Throughput volume was a highlight and ahead of plan for the quarter, noting that the major planned 15- day maintenance shutdown was successfully completed. Gold recoveries were in line with plan at 85.1% while copper recoveries of 82.5% were ahead of plan, partially assisted by higher mine grades and less reliance on stockpile feed.

Greatland Resources Limited | September 2026 Quarterly Activities Report 6 Gold and copper production of 70,131oz and 2,927t respectively was achieved for the quarter, positioning the Company well to deliver FY27 guidance of 260,000 – 300,000 ounces of gold. Costs September quarter actuals Mining costs of $88.1 million were lower than the previous quarter, despite higher total material moved, largely due to improved productivity aided by a higher proportion of mining volumes from the more productive Stage 7 mining areas. Processing costs of $89.5 million were in line with plan, with the increase relative to prior quarters primarily from the higher surface maintenance costs associated with the planned major maintenance shutdown. Sustaining capex of $36.5 million was in line with plan, though higher than the previous quarter which was largely due to underground development activity. Site services of $23.8 million were in line with plan and previous quarters. Stockpiles Closing run-of-mine (ROM) ore stockpiles at 30 September 2026 are estimated at 1.4Mt at an average grade of 0.60g/t Au and 0.09% Cu for contained metal of 27koz Au and 1.2kt Cu. Low grade stockpiles at 30 September 2026 are estimated at 19.5Mt at average grade of 0.33g/t Au and 0.04% Cu for contained metal of 209koz Au and 8.4kt Cu. Total stockpiles processed during the quarter was approximately 0. 4Mt with underground and open pit mined volumes accounting for approximately 90% of total mill feed.

Greatland Resources Limited | September 2026 Quarterly Activities Report 9 Tax instalments of $100 million were paid in the September 2026 quarter, comprising the June quarterly tax instalment of $64 million, following which Greatland was re-assessed for monthly instalments resulting in an additional $36 million of tax payments for July and August 2026. Ongoing monthly PAYG instalments will be made for the rest of FY27 based on an assessed rate of approximately 12% of instalment income (revenue and interest income), as determined by the ATO. In addition, a catch-up tax payment that relates to FY26 of ~$155 million is also anticipated in December 2026. Depreciation and amortisation (D&A) for the quarter was $73 million. Full year FY27 D&A is expected to be $280 to $320 million, weighted towards H2. The increase in D&A from FY26 ($ 144 million) to FY27 results from the increased capital base established at Telfer following the significant investment made since acquisition, particularly from underground development, Stage 7 stripping and tailings storage facility construction. Gold Hedging profile – downside price protection with full upside exposure Greatland continues to maintain full upside exposure to the gold price, while achieving downside price protection through gold put options. Greatland's current gold put options are the following: Table 3: Gold put option program Quarter end date Gold volumes under put options (oz) Weighted Average Strike Price (A$/oz) 31-Dec-2026 37,498 4,200 31-Mar-2027 37,500 5,000 30-Jun-2027 37,500 5,200 30-Sep-2027 37,500 5,000 Total 149,998 4,850 Safety No lost time injury occurred during the quarter, and the 12-month moving average lost time injury frequency rate (LTIFR) is 0.2.
