ASX:SFR Page 2 | 15 Sandfire CEO and Managing Director, Mr Brendan Harris, said: “Our TRIF was 1.8 at the end of Q1 FY27 and we reported seven High Potential Incidents during the period. While our safety statistics compare favourably with industry benchmarks, we continue to believe it is possible to have a workplace that is injury free. That’s why we have continued to pri oritise a multi-faceted work program that is designed to strengthen our safety systems and risk management processes and reinforce those inclusive behaviours that encourage everyone to be a leader and speak up when something doesn’t look or feel right. “We said recently that we are as well placed at an operational level as we have been at any time in the last four years , and we have started FY27 well. We delivered 38.9kt of Group CuEq production in Q1 FY27 to be perfectly aligned with the run -rate required to achieve the mid-point of our annual guidance and we safely completed the planned shutdown of our processing facility at Motheo, having continued to balance throughput with ore grades and recoveries to maximise longer term value. “While the current geopolitical and macroeconomic environment is anything but certain, our low cost operations and particularly strong balance sheet ensure we are very well positioned to safely and sustainably deliver our strategy, and do what we say we will do. We are continuing to closely monitor energy markets given the potential for currently elevated prices to persist and supply chains to be further affected, recognising the greater reliance of Motheo on diesel to undertake its open pit mining operations. Of course, the timely commissioning of our new, dedicated solar facilities at both Motheo and MATSA in H2 FY27 will remain a key focus given the relatively low cost electrons they provide. “Recognising the prior success we’ve had replacing mining depletion , one of the most important elements of our strategy emphasises the value we place on ore reserves and our aspirational goal of having 15 years of life defined for both MATSA and Motheo . The continued ramp-up of exploration activity in Spain, Botswana and Australia reflects this level of intent, and we’re particularly pleased that recent drilling has confirmed the potential of the discovery hole at La Juliana by significantly extending the strike and depth extent of high -grade, massive sulphide mineralisation within close proximity of MATSA’s existing underground footprint. “We are mobilising additional resources at both MATSA and Motheo and will allocate additional funds to accelerate drilling programs at both La Juliana and A4 Underground, and complete concept level studies, to help us better understand the scale and economic potential of these exciting opportunities. “At Kalkaroo, we completed the initial 9km of our planned 130km infill and extension drilling program during Q1 FY27, despite site access being severely restricted by adverse weather for around three weeks. This drilling program and the associated pre-feasibility study remain on track for completion in H2 FY28. “Despite its smaller scale, w e continue to believe that the Black Butte Copper Project in Montana represents a compelling development opportunity given its relatively high ore grade, environmentally sustainable design and minimal surface footprint, and have confirmed our ongoing financial support of Sandfire America (TSX -V: SFR) as their Board undertakes a review of their strategic alternatives, including but not limited to a sale of the company. “Our operational focus on consistency and predictability, and being better at the basics, allowed our teams to take full advantage of buoyant commodity markets and record low TCRCs to generate Group sales revenue of $480M and Underlying EBITDA of $272M, for an Underlying EBITDA margin of 57%. This, in turn, ensured that our $117M fully franked dividend , the first in four years, was effectively funded out of quarterly free cash flow as we finished the period with a net cash balance of $342M. “I would like to thank all of our employees and contractors for their continued diligence and strong start to FY27, whilst reminding everyone that n othing is more important tha n the health and safety of our people.”

Sandfire Resources Ltd. (ABN 55 105 154 185) - ENDS - SUSTAINABILITY Safety During Q1 FY27 we continued to undertake an extensive program of work designed to further strengthen our safety and broader risk management systems, with a particular focus on the verification of critical controls for our identified material risks . In order to achieve an injury free workplace , the behavioural traits of our workforce will arguably be even more important and that’s why we are running a parallel program designed to further embed a psychologically safe environment where everyone feels empowered to speak up, irrespective of their title or level within the organisation. We reported a Total Recordable Injury Frequency (TRIF) of 1.8 at the end of Q1 FY27 (30 June 2026: 1.6), with four injuries and seven High Potential Incidents recorded during the period. Sustainability Construction of our dedicated 33MW solar facility at MATSA remained on schedule for commissioning and ramp-up during H2 FY27, as the installation of solar panels commenced during the period. We also made strong progress with the construction of our dedicated 21MW solar facility at Motheo during Q1 FY27, with supporting structures now in place and solar panel installation underway. Once operational, the facility is expected to supply approximately 30% of the operation’s annual stationary power requirements and be an important element of our decarbonisation pathway in Botswana . The facility will also improve energy security and mitigate exposure to future electricity price increases. Commissioning of the facility is planned to commence in Q3 FY27. During the quarter, we continued to engage with key stakeholders in Botswana and Spain to identify and progress flagship programs under our Strategic Community Investment Approach. The approach allocates 0.5% of Operations EBITDA to initiatives that have the potential to deliver a measurable and lasting benefit to host communities, with $4.7M allocated during FY26.

A planned reduction in copper and zinc ore grades contributed to the temporary decline in ore recoveries and the 16% and 15% reduction in contained copper (13.6kt) and zinc (19.7kt) production, respectively, in the period. Higher ore grades and recoveries are expected across the remainder of the year and annual production guidance remains unchanged. MATSA’s Underlying Operating Unit Cost increased temporarily to $95/t in Q1 FY27 , for an implied C1 Unit Cost of $1.18/lb, as the Euro:US dollar exchange rate remained elevated , global energy markets continued to tighten and our team completed an intensive equipment maintenance cycle. While market-linked diesel and electricity prices are creat ing underlying inflationary pressure, we anticipate the recent retracement of the Euro:US dollar exchange rate to provide important relief as approximately 90% of MATSA’s cost base is Euro-denominated, with annual guidance remaining unchanged. Capital Expenditure We invested $38M at MATSA in Q1 FY27, with $21M directed toward mine development and a further $17M to sustaining and strategic projects. With MATSA’s original tailings facility nearing the end of its useful life, the initial phase of our new tailings storage facility remains on track with commissioning expected in Q2 FY27. MATSA Near Mine and Extension Drilling FY27G Q1 FY27 YTD FY27 Comments Infill and extension drilling (km) 67.0 15.8 15.8 Six rigs (four underground and two surface) across Magdalena, Aguas Teñidas and Sotiel Capitalised expenditure (i) ($M) 5.6 1.0 1.0 Exploration and evaluation expense ($M) 3.0 0.9 0.9 In Spain, we completed 15.8km of infill and extension drilling in Q1 FY27, with six rigs operating across Magdalena, Aguas Teñidas and Sotiel maintaining a primary focus on infill conversion and near-mine extension opportunities. At La Juliana, located approximately 700m south -east of the Castillejitos orebody at Aguas Teñidas, follow-up drilling intersected thick zones of high -grade, polymetallic, massive sulphide mineralisation on both sides of the prior discovery hole CCM-90, extending the target horizon ~160m along strike. Significant intercepts included: • 22.5m @ 0.9% Cu, 15.4% Zn, 3.8% Pb, 0.7g/t Au and 85.2g/t Ag from 310.5m (CCM-91), • 22.2m @ 1.0% Cu, 12.0% Zn, 3.8% Pb, and 127.4g/t Ag from 415.8m (CCM-92) (Au assays and DHEM survey are pending), and • 30.0m @ 0.4% Cu, 10.1% Zn, 4.9% Pb, 0.9g/t Au and 114.4g/t Ag from 323m (CCM-94).
Page 5
ASX:SFR Page 5 | 15 Downhole electromagnetic surveys indicate that the massive sulphide mineralisation may have a strike extent of at least 350m, whilst the prospective geological horizon has been interpreted to have a potential strike extent of up to 2km. We are mobilising additional resources and will allocate additional funds to accelerate the drilling program at La Juliana and complete a concept level study to help us better understand the economic potential of this exciting opportunity. Further details are provided in the ASX release ‘High -Grade Intercepts Extend La Juliana Mineralisation at MATSA’, dated 27 October 2026.

Motheo’s Underlying Operating Unit Cost declined by 12% in Q1 FY27 to $48/t of ore processed, for an implied C1 cost of $0.65/lb, to be broadly aligned with full year guidance as the operation benefitted from its exposure to unprecedented (negative) TCRC rates and our team continued to make strong progress with the Stage 4 cutback of the T3 open pit , where expenditure is capitalised as deferred waste stripping. Motheo remains well supplied with diesel and other critical consumables, with good visibility over near-term supply. Current tightness in global energy markets does, however, create a level of risk as our cost guidance assumes that diesel reverts to ‘pre-conflict’ level prices in H2 FY27. Capital Expenditure We invested $20M at Motheo in Q1 FY27, with ~$14M directed to deferred waste stripping and $3M to sustaining and strategic projects. Our recent acquisition of the highly prospective Kgolo East and West tenements, located north -east of the Motheo hub and in close proximity to the Kho emacau underground mining complex, accounted for a further $3M of expenditure. Motheo Infill Drilling FY27G Q1 FY27 YTD FY27 Comments T3 and A4 infill drilling (km) 31.0 6.5 6.5 Resource conversion and infill drilling progressed at T3 and A4, with 27 drill holes completed for 6.5km in Q1 FY27 Capitalised expenditure (i) ($M) 8.8 1.9 1.9 We completed 6.5km of resource conversion and infill drilling during Q1 FY27, with 27 holes completed across the T3 and A4 deposits. The next phase of drilling within the T3 pit is designed to de-risk Stages 4 and 5 of the mine plan by tightening drill spacing in key mining areas, improving resource confidence and validating grade continuity within the principal ore zones ahead of mining.

Kalkaroo PFS costs (j) ($M) 51 5.1 5.1 Despite adverse weather, which restricted site access for around three weeks during the period, our team made strong progress by completing the initial 8.7km of our planned ~130km infill and extension drilling program, and our rate of progress is expected to ramp-up across Q2 FY27. The broader pre-feasibility study for the Kalkaroo Copper -Gold Project also remains on track for completion in H2 FY28 , with drilling already underway to collect representative samples for metallurgical test work. In parallel, we have continued to work in partnership with the Ngadjuri Adnyamathanha Wilyakali Native Title Aboriginal Corporation (NAWNTAC) to protect their cultural heritage at Kalkaroo, with Traditional Owner heritage representatives remaining actively involved in site activities. Black Butte Copper Project, Montana, USA Sandfire holds an 87% shareholding in TSX -listed Sandfire Resources America (Sandfire America, TSX-V: SFR), which owns 100% of the high -grade Black Butte Copper Project (Black Butte) in Montana, USA. Despite its smaller scale, we continue to believe that the Black Butte Copper Project in Montana represents a compelling development opportunity given its relatively high ore grade, environmentally sustainable design and minimal surface footprint, and have confirmed our ongoing financial support of Sandfire America (TSX -V: SFR) as their Board undertakes a review of their strategic alternatives, including but not limited to a sale of the company. We invested $2M in Black Butte during Q1 FY27.

Exploration and evaluation expense ($M) 16.3 4.0 4.0 In line with guidance. We continued to apply a systematic approach to r egional exploration in the Iberian Pyrite Belt during Q1 FY27, completing 6.1km of drilling across Spain and Portugal for total expenditure of $4.0M. Within Spain, ~70% of activity remained focused on the highly prospective northern corridor, while in Portugal our team completed 1.8km of drilling within the Ourique licence. Kalahari Copper Belt Exploration, Botswana FY27G Q1 FY27 YTD FY27 Comments Near mine, extension and regional (km) 27.5 11.7 11.7 21 holes completed in Q1 FY27 Exploration and evaluation expense ($M) 21.8 6.3 6.3 Expenditure run-rate tracking above guidance due to additional metres drilled Our regional exploration team in Botswana completed 11. 7km of drilling in Q1 FY27, testing three regional targets and a further three within the Motheo Hub . The latter included a continued focus on the extension potential of A1 and the prospectivity of the A4 underground and A4 West zones of enriched copper mineralisation associated with the Ngwako Pan Formation (NPF) contact. To date, we have confirmed that enriched NPF contact mineralisation at A4 is concentrated approximately 200m below the pit shell and extends West over hundreds of metres, highlighting the scale of the opportunity should it prove to be continuous. We are mobilising additional resources and will allocate additional funds to accelerate the drilling program designed to test the continuity of enriched NPF contact mineralisation at A4 and complete concept level studies to help us better understand the economic potential of this exciting opportunity. Curnamona Province, South Australia FY27G Q1 FY27 YTD FY27 Comments Regional drilling (km) 50 3.9 3.9 Drilling activities were delayed due to weather conditions Exploration and evaluation expense ($M) 13.7 1.7 1.7 Under the terms of our Strategic Alliance Agreement with Havilah, Sandfire funds all of the partner’s regional exploration activities undertaken within the Curnamona Province , with the agreed scope managed and executed by Havilah. With access having been restricted by adverse weather d uring Q1 FY27, Havilah reprioritised the planned drilling program and commenced RC drilling at the Brooks Dam prospect, which is ~ 12km north-west of Kalkaroo. A second RC rig is being mobilised and is expected to commence drilling at the Homestead prospect in Q2 FY27, directly west along strike from Kalkaroo.

ASX:SFR Page 11 | 15 Notes (a) CuEq for FY26 and FY27 are calculated based on the following average forward prices for FY27 in USD as at 30 June 2026 (all in USD): Cu $13,280/t, Zn $3,456/t, Pb $1,927/t, Ag $58.9/oz. Guidance for Payable Metal is based on current commercial terms. Copper equivalent is calculated using the following formula: Copper metal tonnes + Zn metal tonnes x (Zn price/Cu price) + Pb metal tonnes x (Pb price/Cu price) + Ag metal ounces x (Ag price/Cu price). (b) Unaudited financial information. (c) Underlying measures provide insight into Sandfire’s core business performance by excluding the effects of events that are not part of the Group’s usual business activities, but should not be indicative of, or a substitute for, profit/(loss) after tax as a measure of actual operating performance or as a substitute to cash flow as a measure of liquidity. (d) Debt and Net cash/(debt) excludes capitalised transaction costs, leases, accrued interest, and revolving short-term (VAT) working capital facilities. (e) Calculation discrepancies may occur due to rounding, with production statistics are subject to change following reconciliation and finalisation subsequent to the end of the quarter. All FY26 and FY27 CuEq production figures, Underlying Operating Costs and implied C1 unit costs, are a function of specific prices which can be found in these notes. Unless otherwise stated all currency figures are USD. Figures in Italics indicate that an adjustment has been made since the figures were previously reported. (f) Refer to Appendix A for further details relating to mining, processing, sales, costs and capital expenditure. (g) Underlying Operating Costs – MATSA: Includes costs related to mining, processing, general and administration and transport, and excludes shipping costs which are offset against sales revenue for statutory reporting purposes. Motheo: Includes costs related to mining, processing, general and administration, transport (including shipping) and royalties. Underlying operating cost guidance excludes changes in finished goods inventories. (h) C1 Costs include mining, processing general and administration and transport (including rollback for MATSA). (i) Infill and extension drilling expenditure is included in Strategic and Sustaining capital. (j) Kalkaroo PFS costs are included in Exploration and Development Projects capital expenditure and includes all capitalised expenditure related to the Kalkaroo project, including infill and extension drilling. (k) Includes exploration outside the mine halo and does not include infill and resource drilling. (l) FY27 Estimates refer to single point estimates which provide the build up to the mid-point of the guidance range. (m) Q1 FY27 actual split of C1 Costs: MATSA: Mining 52%, Processing 24%, G&A 12%, Transport 11%. Motheo: Mining 47%, Processing 21%, G&A 14%, Transport 18%.
