We are proud of the strong platform we have built on which to achieve our Purpose – to generate superior shareholder returns, and deliver our five-year profitable growth strategy in FY26, targeting 2Moz production. In FY23 gold sales of 1,563koz were delivered within revised guidance at an AISC of A$1,759/oz. The safety and wellbeing of our people is integral to our success. With TRIFR at 3.2, well below industry average, we have again delivered strong operational performance safely and responsibly in FY23, consistent with the STARR Core Values of Safety, Teamwork, Accountability, Respect and Results. Our focus is centred on delivering safety leadership at all levels of the business to strengthen the culture and hazard awareness across our operations. We maintain our focus on the organic growth of the three large scale production centres which we operate in the world class locations of Western Australia and Alaska USA, through targeted exploration programs and expanding the operating lives of our operations by investing in expansions to maximise efficiencies. For instance: • at the Kalgoorlie Production Centre, we announced the Final Investment Decision in June to expand the Fimiston processing plant, increasing throughput from 13Mtpa to 27Mtpa by FY29 (steady state), simplifying the plant design and delivering a sustained lower cost base. Expanding the processing capacity will strengthen our portfolio, materially increasing free cash flow generation and sustain hundreds of local jobs, economic and social investment, and local procurement opportunities in the Goldfields region; • at the Yandal Production Centre we are optimising future ore feed sources for the expanded Thunderbox processing plant, advancing to delivery of the 6Mtpa name plate capacity, and • at the Pogo Production Centre, we are lowering costs through growth and optimisation, following an exceptional Q4 exceeding the key growth objective of 300ktpa of gold sold. Northern Star is in a financially robust position, with FY23 activity generating cash earnings of over $1.2 billion. At 30 June 2023 we held net cash of $362 million and liquidity of $2.2 billion, all underpinned by a solid platform of 57.4 million ounces of Mineral Resources and 20.2 million ounces of Ore Reserves. Interim and final dividends paid to our shareholders during FY23 totalled $261 million including dividends reinvested under our Dividend Reinvestment Plan, whilst the inaugural share buy back announced on 29 August 2022 returned another $127 million to our shareholders. Northern Star’s disciplined capital allocation priorities remain returning cash to shareholders, investing in organic profitable growth, and maintaining a strong balance sheet, notwithstanding a challenging cost environment. In FY23 we were pleased to achieve three investment grade credit ratings with Moody’s, S&P and Fitch, and subsequently in April we issued US$600 million of senior guaranteed notes due in April 2033 under Rule 144A of the US Securities Act, at an interest rate of 6.125% per annum. The cash will be used for general corporate purposes including capital expenditure such as funding the KCGM mill expansion. Integral to this is the significant hard work and dedication delivered by our workforce during FY23, and the quality of our relationships with other stakeholders including the Traditional Owners in the communities in which we operate. On behalf of the Board, we hope you enjoy reading this Report, and we thank you for your support as a shareholder. Yours sincerely Stuart Tonkin Managing Director & CEO Michael Chaney AO Chairman Gold pour at Thunderbox, Yandal.

NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 Operating & Financial Review OPeRaTinG anD FinanCial Review OPeRaTinG anD FinanCial Review Operations Review This Operating and Financial Review outlines key information on our FY23 operations, financial position, and our business strategies and prospects for future financial years. It supplements, and should be read in conjunction with, our Financial Report. Our efforts during FY23 have created an enviable platform for us to realise and deliver on our five-year growth strategy through to FY26. Northern Star maintains focus on the organic growth of our assets through targeted exploration programs and expanding the operating lives of our existing operations to generate superior returns for shareholders. To progress achievement of our Net Zero Ambition, in FY23 our technical teams focused on identifying specific renewable projects for commissioning in FY24, including the Power Purchase Agreement entered into for the Jundee renewable energy project. More information is available in Northern Star's FY23 Sustainability Report at https://www.nsrltd.com/sustainability. Evaluating potential acquisitions and investing in exploration to unlock value from the gold endowment across our highly prospective ground, located exclusively in the low sovereign-risk jurisdictions of Australia and North America, remains the Company’s strategy for growth. FY23 Operations Review Northern Star has had a strong year again in FY23, meeting production and revised cost guidance,1 achieving record performance at multiple operations, and maintaining safety performance well below industry average in a dynamic, challenging operational environment. The FY23 exploration program was successful in replacing Mineral Resources and Ore Reserves, as depleted by mining activity. Group Resources were maintained at 57.4Moz, and Reserves steady at 20.2Moz over the 12-month period to 31 March 2023, post depletion. The performance of our Kalgoorlie Production Centre (including KCGM) in Western Australia, and our Pogo Production Centre in Alaska, USA delivered FY23 production and revised cost guidance.1 Production performance at Pogo achieved a milestone rate of over 80,000oz of gold sold in Q4. Jundee, at our Yandal Production Centre in Western Australian, achieved record performance in underground ore tonnes mined in Q4. Growth capital expenditure of A$752 million was above revised expectations primarily from KCGM Mill Expansion early works and procurement of long-lead items, increased capital drilling at Jundee (Yandal) and commercial production being declared later than planned at Otto Bore (Yandal). Maintaining our Resource and Reserve levels is crucial to achieving our five-year strategy to grow production to 2Moz per annum by FY26. In the second year of the strategy we delivered significant progress towards securing the profitable growth pathway: • Kalgoorlie Production Centre: Material movement at KCGM increased by 26% to 83Mtpa, within the FY26 target of 80-100Mtpa. This material movement is critical to the long-term development of our largest and longest life asset in KCGM; • Yandal Production Centre: The Thunderbox mill expansion project advanced towards delivering its 6Mtpa nameplate capacity; and • Pogo Production Centre: Following completion of the mill expansion in FY22, FY23 focused on cost optimisation initiatives. 18 Table 1 Mine Operations Review 19 Metrics Total Material Mined Total Material Milled t t Head Grade gpt Recovery % KCGM Carosue Dam Kalgoorlie Operations Jundee Thunderbox & Bronzewing Pogo Total 6,903,596 5,103,022 2,068,667 2,749,239 6,469,891 1,230,528 24,524,943 12,478,744 3,746,655 2,053,311 3,018,365 4,003,854 1,228,793 26,529,722 1.3 84 2.2 93 2.8 88 3.6 91 1.4 89 6.9 88 2.12 88 Gold Recovered Oz 432,152 243,246 161,196 320,201 159,782 239,011 1,555,588 Gold Sold Oz 432,001 245,304 163,679 320,341 157,635 243,633 1,562,593 All-in Sustaining Cost A$/Oz 1,596 1,885 1,876 1,365 2,116 2,1283 1,7593 Excavator sorting ore at Jundee, Yandal. 1.

An approved expansion of the Fimiston Processing Plant was announced on 22 June 2023 to increase mill capacity from 13Mtpa to 27Mtpa by FY29 (including 2-year ramp-up). This sets up the next phase of enhancement for KCGM, one of the world’s largest gold mines, to produce the targeted 900kozpa by FY29.4 exploration Exploration activity continued as part of a multi-year growth program across the KCGM Operations. Exploration and resource definition drilling continued from both surface and underground targeting extensions to the mineralised system below, and to the north, of the Fimiston Super Pit and historical underground workings. This ongoing program was successful in incrementally increasing Open Pit Mineral Resources and Ore Reserves across the year. Carosue Dam Operations Underground exploration drilling also continued across the Fimiston North area. Drilling from the underground platform at Fimiston North continued to achieve strong results increasing the Fimiston Underground Mineral Resource to 66Mt at 2.4g/t for 5.1Moz. At the Mount Charlotte underground operation, exploration drilling from the recently rehabilitated 32 Level targeted down-plunge extensions of the Main COB, MOB and ROB ore systems. Early results underpinned a 23% increase in Mineral Resources for the Mt Charlotte area to 58Mt at 1.9g/t for 3.6Moz together with a 10% increase in Ore Reserves to a total of 21Mt at 2.0g/t for 1.3Moz. Future underground exploration and infill drilling programs will target further growth of the Mt Charlotte stockwork vein complex and test multiple mineralised zones adjacent to existing mine infrastructure, including Hidden Secret, Duke, Little Wonder, Mt Ferrum and Fairplay. Kalgoorlie Operations Production - South Kalgoorlie & Kanowna Belle In FY23 Kalgoorlie Operations ore production was sourced primarily from the underground mines at the Kanowna Belle and South Kalgoorlie Operations. Overall, Kalgoorlie Operations delivered lower production of 2,068,667 tonnes in FY23 (FY22: 2,336,085 tonnes) with the reduction attributed to: • consolidation of mill production to a single mill at Kanowna Belle, as a result of the Jubilee mill at South Kalgoorlie Operations being placed on care and maintenance in Q1; • • the FY22 production figure including over 52,000 tonnes of ore from the Kundana Assets,6 divested to Evolution Mining Ltd in August 2021; and the South Kalgoorlie Operations mine production profile was reduced overall, to allow focus on higher grade orebodies. The lower ore production naturally resulted in a reduction in total gold sold in FY23 of 163,679oz (FY22: 174,918oz). Despite this, we were able to improve the AISC performance by A$73/oz to A$1,876/oz (FY22: A$1,949/oz). exploration – South Kalgoorlie In-mine exploration drilling across the northern area of the mine at South Kalgoorlie Operations has successfully identified further extensions to the Mutooroo ore zone by more than 200m along strike. The MUT ore zone remains open both along strike and down plunge along this high- grade mineralised structure. Regionally, a new discovery was made at the Hercules prospect, located approximately 20km west of the HBJ deposit in the historical Penfolds gold mining camp. Diamond and reverse circulation (RC) drilling beneath a 1.5km-long supergene gold anomaly has returned mineralised bedrock intercepts of significant width and grade over a 500m strike length. Further drilling is planned to evaluate the resource potential of the prospect. This exciting discovery highlights the future potential that still exists across the broader Kalgoorlie region and within easy trucking distance to the Company’s existing and proposed infrastructure. exploration – Kanowna Belle Continued drilling success within the Kanowna Belle underground mine at Joplin has resulted in an increase in the Inferred Mineral Resource at Kanowna Belle by 322koz to 2.7Moz. The Joplin system is located less than 300m from the active mining area at Velvet and has been delineated over a 1.4 kilometre strike length and to a vertical depth of 1 kilometre. Infill drilling will continue next year to extend the limits of mineralisation and support a mining prefeasibility study. At Red Hill, located 3.5 kilometres east of the Kanowna Belle processing plant and 22 kilometres from the Fimiston processing plant at KCGM, exploration drilling has returned thick intersections of gold mineralisation hosted in a large porphyry intrusive which is amenable to bulk mining operations. Mineral Resources have increased to 32.4Mt at 1.1g/t for 1.2Moz with future drilling focused on extending the mineralisation along strike and down dip. 21 Production Carosue Dam Operations processed 3,746,655 tonnes in FY23 (FY22: 3,780,584 tonnes). Total ounces of gold sold increased in FY23 to 245,304oz (FY22: 239,681oz). FY23 AISC was A$1,885/oz (FY22: A$1,785/oz). exploration Continued resource definition drilling at the Qena prospect returned some excellent high-grade results, driving an increase to the Mineral Resource by 120koz to total 6.1Mt at 2.2g/t for 430koz. The Q4 result was exceptional compared to earlier quarters in FY23, with improved performance delivering cost reductions in underground mining costs of 31%, open pit mining costs of 23% and processing costs of 28%.5 Prefeasibility studies have commenced to outline a potential surface and underground mining operation ahead of further extensional drilling programs. 4.

Gold sales for FY23 increased by 19% to 157,635oz (FY22: 132,551oz). FY23 AISC was A$2,116/oz (FY22: A$1,817/ oz). Optimisation efforts continue to advance towards delivering Thunderbox processing plant nameplate capacity of 6Mtpa. Ore from the Orelia pit at Bronzewing Operations was processed for the first time during Q4. Q4 saw open pit volumes 16% higher than the previous quarter, while underground volumes were 10% higher. exploration - Thunderbox In FY23 exploration across the Wonder Shear Zone, approximately 25km south of the Thunderbox processing plant, continued with impressive drilling results reported from the Wonder West, Wonder North and Golden Wonder deposits. This work has resulted in an increased Mineral Resource of 9.8Mt at 2.9g/t for 921koz for the Wonder project area. Exploration drilling has intersected significant new mineralisation on the Bannockburn Shear Zone, approximately 500m north of the Bannockburn open pit. Previous exploration in this area has been limited with recent drilling successfully identifying thick high-grade intersections in the same geological setting as the main Bannockburn mineralisation. Exploration is ongoing to define and extend this newly identified mineralised zone. exploration - Bronzewing Exploration activities in the Bronzewing district targeted early-stage prospects located on the Company’s extensive landholdings surrounding the Orelia and Corboys projects. This work is part of a multi-year exploration strategy to systematically screen the highly prospective Yandal greenstone belt for new gold resources. Pogo Production Centre Pogo Operations Fairbanks Steese National Conservation Area Pogo North Pole Delta Junction ANCHORAGE Lake Clarke National Park and Preserve Production FY23 saw record performance at Pogo in Q4 with record tonnes milled and gold sold since acquisition, 347,524 tonnes and 80,029oz respectively, above the key growth objective of 300kozpa gold sold. Gold sold at Pogo in FY23 totalled 243,633 ounces which exceeded our FY22 result of 214,216oz. AISC was US$1,431/oz (A$2,129/ oz). Q4 delivered exceptional results when compared to FY23 earlier quarters, with significant cost reductions in unit underground mining costs of 41% and processing costs of 37%.8 exploration Ore Reserves at Pogo Mine were largely unchanged at 1.6Moz at an increased grade of 8.6g/t as in-mine drilling activity focused predominantly on operational requirements within the Pogo system.

Ore Reserves for the Australian Operations were estimated at an assumed gold price of A$1,850/oz. Reserves for the Pogo Operation were estimated at an assumed gold price of US$1,400/oz. Reported in ASX release “Resources, Reserves and Exploration Update” on 4 May 2023 which is also found on Northern Star’s website (https://www.nsrltd. com/investor-and-media/asx-announcements). Group Mineral Resources Estimate increased significantly by 27.1 million tonnes from 31 March 2022 to 892 million tonnes, with grade remaining steady at 2.0 grams per tonne gold for 57.4million ounces as at 31 March 2023. Mineral Resource additions to 3.5Moz from exploration demonstrates the value generated by the Company’s sustained exploration investment, more than offsetting mine depletion and divestments. In addition, it reinforces Northern Star’s strategy to identify growth opportunities within strongly endowed geological terrains that can deliver maximum returns to shareholders. Group Proved and Probable Ore Reserve remained stable, with 20.7 million ounces gold as at 31 March 2022 compared to the current 20.2 million ounces gold at 31 March 2023, after mining depletion of 1.8 million ounces.

NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 OPeRaTinG anD FinanCial Review OPeRaTinG anD FinanCial Review Financial Review FY23 delivered record revenue of $4.1 billion, building on the Company's strong balance sheet which continues to serve as a solid foundation to support our profitable growth strategy. Key financial outcomes from our FY23 operations are highlighted below. Strong operating & free cash generation Robust returns to shareholders As a result of the strong production and gold price realised during the year, the Company generated Underlying EBITDA of $1.5 billion (FY22: $1.5B). This translated into operating cash flows of $1.4 billion (FY22: $1.6B) and underlying free cash flows of $359 million (FY22: $477M), highlighting the Company’s continued ability to generate cash from operations while investing in its future. Growth in Cash earnings The Company achieved growth in Cash Earnings1 to $1.2 billion, representing a 16% increase on FY22, and demonstrating the Company's robust performance. Margin focus Gold revenue increased 9% to $4.1 billion, primarily driven by an 8% increase in average realised gold price to $2,639 per ounce (FY22: $2,433/oz), with gold sold remaining consistent year on year at 1,562,593 ounces (FY22: 1,560,958oz). Cost of sales increased 8% to $3.5 billion (FY22: $3.3B), mainly driven by inflationary pressures in some cost components. Controlling costs remains a strong focus and is a key element of our strategy to unlock value. A final unfranked dividend of 15.5 cents per Share has been approved, taking total FY23 dividends to 26.5 cents per Share. Solid operational performance FY23 results were generated from strong operational performance across KCGM, Carosue Dam, Kalgoorlie Operations, Jundee, Thunderbox & Bronzewing, and Pogo for the full year FY23, as set out in Table 1 below. Clear organic growth pathway We continued to make strides and achieved significant progress in the second year of our five-year profitable growth strategy towards 2Mozpa production by FY26: • Kalgoorlie Production Centre: Material movement at KCGM increased by 26% to 83Mtpa, within the FY26 target of 80-100Mtpa;2 • Yandal Production Centre: The Thunderbox mill expansion project advanced towards delivering its 6Mtpa nameplate capacity; and • Pogo Production Centre: Following the Mill expansion in FY22, FY23 focused on cost optimisation initiatives. The Company’s robust balance sheet and liquidity continues to underpin its organic growth strategy. At 30 June 2023, the Company had cash and bullion of $1,247 million.

NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 OPeRaTinG anD FinanCial Review OPeRaTinG anD FinanCial Review income Statement Figure 4 EBITDA (A$M) Balance sheet The results and commentary below relate to the 12 months ended 30 June 2023 during which the Group reported a statutory profit after tax of $585 million, a 29% increase from the prior year (FY22: $452M). This increase in statutory profit after tax was largely due to write back of the previously recorded $437 million write- down relating to sub-grade ore stockpiles at KCGM offset by the prior period gain of $298 million recorded on the sale of Kundana, Paulsens and Western Tanami. Total Gold sold in FY23 remained steady across all operations compared to the prior year. Jundee, Carosue Dam, Pogo, and Thunderbox & Bronzewing all increasing production year on year. This was offset by KCGM and Kalgoorlie operations being down compared to the prior year, due to the South Kalgoorlie mill being placed on care and maintenance in Q1 FY23 and KCGM incurring greater mill downtime than the prior year. Cost of sales increased 8% to $3.5 billion (FY22: $3.3B), driven by higher activity across the Group and inflationary factors experienced across labour, power, reagents, maintenance, accommodation and camp costs during the period. A non-cash inventory write-back of $437 million (FY22: $nil) has been recognised in relation to the previously written-down sub grade stockpiles at KCGM. The approval of the mill expansion project at KCGM 30 $1,943 $1,773 10% FY22 FY23 provided greater certainty and timing for the processing of these stockpiles. Non-cash impairments of $42 million (FY22: $52M) were recognised in respect of exploration and evaluation assets. The Group reported Cash Earnings1 of $1.2 billion for FY23, which is 16% higher than the prior year (FY22: $1.05B). As a result of merger accounting and the Company’s focus to generate superior returns, Cash Earnings provides shareholders with an improved understanding of the Company’s performance, relative to statutory earnings, as it reflects sustaining free cash flow of the business. Table 3 Net Profit After Tax to EBITDA, Underlying EBITDA and Cash Earnings Reconciliation Current assets increased as at 30 June 2023 to $2.1 billion (FY22: $1.4B) which was led by the increase in cash and cash equivalents, driven by generated operating cashflows and the inaugural issuance of USD$600 million of Senior Guaranteed Notes, due April 2033 (Notes). Bullion awaiting settlement increased to $114 million from $57 million at 30 June 2022 which was received as cash during July 2023. Non-current assets also increased by $502 million primarily due to the write back of $437 million previously written down sub-grade stockpiles at KCGM. Current provisions reduced to $176 million from $316 million predominantly due to a $155 million provisional payment of duty relating to the merger with Saracen. Non-current borrowings increased by $799 million to $1.1 billion at 30 June 2023 as result of the Notes issuance which was partially offset by the repayment of corporate bank debt. Cash flow Cash flows from operating activities for the 12 months ended 30 June 2023 were $1.4 billion, being 17% lower than the previous financial year, driven principally by the payment of duties of $158 million and the receipt of lower tax refunds by $65 million. Receipts from customers were $4.1 billion, an increase of 9% compared to the prior period, predominantly due to the increased revenue driven by an 8% increase in average realised gold price. Payments to suppliers and employees increased 17%. This increase is driven primarily by inflationary factors experienced across labour, power, reagents, maintenance, accommodation and camp costs during the period. Cash outflows from investing increased 14% when compared with FY22. The reason for the increase was due to the $304 million net proceeds in FY22 from the sale of the Kundana assets, as offset by the acquisition of the Newmont Power Business and payment of $169 million for the Osisko Mining Inc debenture. plant and equipment and mine properties increased by $20 million, due to continued capital invested in mine development across all operations offset by reduced spend on property, plant and equipment with the completion of the Thunderbox Mill expansion early in FY23. Investment in exploration increased by $18 million when compared to the prior period. Cash inflows from financing activities were $246 million for the year ended 30 June 2023, which was due to the Notes issuance offset by payments for finance leases, the repayment of the corporate bank debt and the returns to shareholders through dividends and the share buy-back program. The Company continued to make substantial returns to shareholders in line with the Company’s policy of 20% to 30% of Cash Earnings, with $261 million of dividends (FY22: $227M) being paid in FY23. Further, 42% of the A$300 million on-market share buy-back program was completed. 31 Net Profit After Tax Tax Depreciation & Amortisation Interest Income Finance Costs EBITDA Financial Instrument Fair Value Adjustments Impairment of assets Write back of inventory stockpiles Acquisition & Integration Costs Loss on extinguishment of KCGM power contract Delivery of Saracen non-cash hedge book Gain on Disposal of Subsidiary and assets A$M A$M A$M A$M A$M A$M A$M A$M A$M A$M A$M A$M A$M (Gain)/Loss on disposal of property, plant and equipment A$M Underlying EBITDA Tax & Net Interest Paid Sustaining Capital Cash Earnings A$M A$M A$M A$M FY23 585.2 259.6 1,058.7 (25.8) 64.9 1,942.6 (10.4) 42.3 (436.6) - - (0.5) - (0.6) 1,536.8 (2.9) (311.0) 1,222.9 FY2212 452.1 189.9 1,110.5 (6.0) 26.4 1,772.9 (0.8) 52.4 - 7.4 19.4 (4.5) (297.9) 0.3 1,549.0 (83.4) (412.0) 1,053.6 Change (%) Investing cashflows included payments for property, 29% 37% (5%) 332% 146% 10% 1200% (19%) 100% (100%) (100%) (89%) (100%) (306%) (1%) (96%) (25%) 16% Table 4 Free Cash Flow Free Cash Flow Mergers and acquisitions13 Net (Sale)/Purchase of Investments Osisko Mining Inc.

Growth strategy Our second year of our five-year strategy delivered significant progress: • Kalgoorlie – material movement at KCGM of 83Mtpa (targeting 80-100Mtpa by FY26); • Yandal – Thunderbox mill expansion advances towards delivering 6Mtpa capacity; and • Pogo – focus on cost optimisation initiatives. The Company’s robust balance sheet and available liquidity supports this organic growth strategy, with liquidity at 30 June 2023 of $2.2 billion (cash and bullion and $1.0B of undrawn revolving credit facilities). See Figure 3 on page 34 for a summary of the Company's progress towards becoming a 2 million ounce per annum lower cost gold producer, across 3 to 5 production centres, with 20+ year mine life. 32 Geoff Hannan, Dump Truck Operator, Thunderbox, Yandal Figure 1 Northern Star’s five-year strategy to 2.00Mozpa by FY261 Our profitable growth plan 2.00Moz 1.75Moz to 1.60Moz Kalgoorlie Grade increase at KCGM 1.1Moz Sustainable Business 3-5 Production Centres 1.8–2.2Moz Gold Sold 1.56Moz Yandal Realising full potential Pogo Sustainably low-cost 600koz 1st Half Cost Curve 300koz +20yr Life of Mine 33 FY23 FY24 FY26 Generate superior returns Strong cash flow generation World-class assets Profitable Growth Responsible Producer Delivery of KCGM Growth Project In June 2023, the Company announced the A$1.5 billion KCGM Mill Expansion Project, to increase and modernise KCGM’s processing capacity from 13Mtpa to 27Mtpa.2 The three-year construction phase has commenced, with ramp-up from FY27 towards steady-state of 27Mtpa by FY29. The Project will be fully funded from cash on hand plus forecast cash flow, and is consistent with our purpose to significant generate superior returns for our shareholders. The Feasibility Study demonstrates the Project is financially compelling: post-tax IRR of 19% and 4.6 year payback (at A$2,600/oz gold price). Expanding the processing capacity of KCGM will strengthen Northern Star’s portfolio, materially increase our free cash flow generation and progress our five-year strategy to be within the 2nd quartile of the global cost curve. As with any major project, there are risks associated with completing the KCGM Growth Project within the planned scope, budget, and schedule. Delay of the project, or failure to complete it on budget could result in significant financial losses, operational disruptions, and reputational damage. More detail on how we are managing this risk can be found in the Strategic Risk register – see Table 1 on page 38. 1.

These may affect the future financial performance and position of the Company. We have disclosed strategic risks to which Northern Star has an exposure, potential adverse impacts of those risks, and examples of key control measures in place – see Table 1 on page 38. Also included in the next section is a discussion on the Company’s risk management processes, including specific disclosures around climate-related risks and cyber security risks. FY24 growth projects Northern Star is safely executing its operational improvement and growth project pipeline while responsibly advancing its strategic purpose to deliver superior returns to shareholders. The Company’s FY24 growth program is fully funded and aligns with our capital management framework of allocating capital to those projects that deliver superior returns. Northern Star’s financial position remains strong, with net cash of $362 million and liquidity of $2.2 billion (cash and bullion, and $1.0B of undrawn revolving credit facilities). Major growth projects, which accounts for ~80% of the FY24 growth capital budgeted expenditure of $1,150 to $1,250 million, are set out in Table 1 below.

Ramone The Ramone solar energy farm installation is expected to be commissioned in the first quarter of FY24. FY26 outlook Northern Star’s assets are well placed to deliver our profitable growth strategy to 2Mozpa by FY26. The Company is focused on the disciplined and transparent allocation of capital and will not grow for growth’s sake. Northern Star will continue to review and optimise our portfolio for greater financial and shareholder returns, in line with our stated Purpose. NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 OPeRaTinG anD FinanCial Review OPeRaTinG anD FinanCial Review Risk Management We continue to mature and evolve our risk management framework and systems to support diligent and defensible decision making in pursuit of our growth strategy. Northern Star acknowledges that risk is an inherent part of operating our business, with effective risk management considered vital to delivering on our objectives and continued growth. We are committed to enhancing the effective identification, assessment and management of risk associated with our corporate activities and operations to ensure the sustainability and growth of our business. Northern Star’s approach to risk management is underpinned by a view that management, employees and contractors are collectively responsible for identifying and managing the Company’s risks, with the Board responsible for oversight of risk management and setting the risk appetite of the organisation. The risk appetite is demonstrated through the Company’s risk assessment criteria, strategic risk register, policies, standards and Code of Conduct. The focus of the Board and Executive management is on ensuring that all major business decisions are made with due regard to the risks and opportunities associated with such decisions. A crucial element underpinning Northern Star’s risk management is our Company culture. Our Company culture is guided by our Code of Conduct and STARR Core Values that promote a positive culture requiring transparency, honesty, integrity, ethical behaviour, and accountability. 36 Alex Van Der Sluis, Apprentice Auto Electrician, Jundee, Yandal Risk management framework Our corporate and operational risk management activities are guided by Northern Star’s risk management framework, comprising a Risk Management Policy and Standard, risk architecture and risk and assurance system. The framework is aligned to ISO 31000 Risk management guidelines and provides a consistent approach to the assessment, management and reporting of risks across the organisation. The framework is overseen by the Audit & Risk Committee (ARC), Figure 1 Risk management framework comprised of four of the Company’s independent Directors, who have a significant understanding of material risks in the industry and jurisdictions in which Northern Star operates. The ARC make recommendations to the Board on the risk management framework and monitor the strategic risks. Figure 1 illustrates responsibilities for implementing our risk management framework and processes. Board of Directors Risk governance & oversight audit & Risk Committee • Make recommendations to the Board relating to the risk management framework • Monitor the strategic risks • Monitor & review financial risks & mitigating controls Other Board Sub Committees Monitor risks relevant to their areas of oversight, e.g. • ESS Committee monitors climate change related risks • Audit & Risk Committee monitors cyber security risks external auditors internal audit & Risk • Conduct audit to manage risks related to financial statements • Improve the Group risk management framework • Share information • Internal Audit • Oversee external providers of internal audit executive Team • Review strategic risks (quarterly & annually) • Monitor & report operational risks Operational Management Identify, assess and report operational risks 37 Key Strategic Risks The achievement of Northern Star’s strategic objectives is subject to various risks and uncertainties, some of which are beyond our control. Table 1 on page 38 sets out a summary of Northern Star’s key strategic risks, being those which have the potential to have a material impact on the achievement of strategic objectives, including impacting on business, operating and/or financial results and performance and fulfilment of our growth aspirations. Our strategic risks are categorised as risks to Operational Performance, Social Licence to Operate, Growth or as External risks and include the key environmental1 and social2 risks to which the Company has a material exposure that are likely to affect Northern Star’s financial condition or operating performance.3 These risks may arise individually, simultaneously or in combination and are not intended as an exhaustive list of all the risks and uncertainties associated with the business. Examples of how the Company manages these risks is also provided. Rolling quarterly reviews of specific strategic risks are undertaken with accountable Executive Strategic Risk Owners with any changes and emerging risks presented to the Audit & Risk Committee and Board. An annual review of the Company’s full strategic risk profile is also undertaken, comprising an external horizon scan, peer review and extensive internal stakeholder consultation. The annual review aims to uncover new and emerging risks, identify potential future changes to the risk profile and informs the Company’s Internal Audit Plan. 1. As defined in the ASX Corporate Governance Council Principles and Recommendations (4th Ed.). For example, it includes risks of polluting or degrading the environment, adding to carbon levels in the atmosphere or threatening a region's cultural heritage. 2. For example, modern slavery risk, mistreating employees or suppliers, harming the local community and risks associated with pandemic. 3.

We have made several asset acquisitions (Echo, Pogo, KCGM, Kalgoorlie power business), undertaken a merger (Saracen) and disposed of assets (Western Tanami Gold Project and Paulsens gold mine and processing plant, Kundana assets) in recent years. Our decision to acquire or develop properties or interests in mines is based on a variety of factors. Other than historical operating results, these factors are uncertain and could have an adverse impact on our financial and operating results, liquidity, as well as the process used to estimate Mineral Resources and Ore Reserves. As a result, any acquisitions Northern Star undertakes, or has undertaken, may not result in Northern Star being able to maintain or increase our Mineral Resources and Ore Reserves, which could negatively impact our financial and operating results, financial condition and future prospects. Further, any difficulties or delays in achieving successful integration of any acquisitions or mergers could have an adverse effect on our business, operating results and financial performance. Divestments also involve risks, including a purchaser defaulting or Northern Star being unable to consummate divestments on acceptable terms and/or in a timely manner. Therefore, divestments could also have an adverse effect on our financial results and financial condition. lanD aCCeSS & aPPROvalS Access to land for exploration and mining activities requires various access agreements and approvals, including native title, heritage, environmental, and third party. Once approvals/agreements are in place, the organisation must comply with the terms of the agreement or conditions of approval. Change to existing agreements and/or failure to comply with existing agreements may result in loss of leases or licences or result in challenges when acquiring new leases. Not obtaining approvals/agreements on time, or at all, could cause delays to mine expansions and adversely impact mine plans and/or major project approvals. Changes to existing agreements and/or failure to comply with existing terms or conditions may result in fines or loss of tenure. DeliveRY OF KCGM GROwTH PROJeCT Failure to, complete the KCGM Growth Project within the planned scope, budget, and schedule could result in significant financial losses, operational disruptions, and reputational damage. ManaGinG ReSOURCeS & ReSeRveS Uncertainty and potential discrepancies between estimated and actual quantities, grades, and recoverability of gold deposits could result in overestimating or underestimating the quality and economic viability of the Company's Mineral Resources and Ore Reserves. Should we encounter mineralisation, geological or mining conditions at any of our mines or development projects materially different from those estimated or predicted from historical drilling, sampling and similar examinations, mining plans may have to be altered. It may also take many years from the initial phase of drilling before production is possible, and during that time the economic feasibility of exploiting a deposit may change. Estimates which were valid when originally estimated may change significantly over time as new information becomes available. Underperformance of our resource/reserve base could result in reduced profitability and net cash flows, variation to mine plan, reduced mine life, missing guidance, and reputation damage. • Comprehensive due diligence conducted on all merger, acquisition and divestment activity, including external expert input as needed. • Disciplined merger, acquisition and divestment decisions are made in line with Board-approved assumptions and return requirements. • Appropriate integration risk identification, planning and change management is undertaken. • Risk assessments & risk management plans implemented. • Ongoing and effective communications with governments and regulatory authorities. • Engagement with Traditional Owners and third parties. • Dedicated project management team. • Project Controls systems and team to manage, monitor and report on budget, schedule, contractor performance and project risk. • Clearly defined scope, based on Scoping and Pre-Feasibility Studies. • Robust project governance including Steering Committee. • Conduct comprehensive exploration programs with systematic sampling and testing to ensure accurate data collection and assessment of resource quality. • Adhere to regulatory requirements and reporting standards for resource and reserve estimation, ensuring transparency and accuracy in public disclosures to investors, stakeholders, and regulators. • Application of appropriate industry standard quality assurance and quality control protocols that covers sampling and analytical processes. • Engage independent experts or consultants to conduct audits and reviews of resource estimation methodologies, ensuring accuracy, transparency, and adherence to industry standards and best practices. • Regularly monitor and update resource and reserve estimates based on new information and data obtained from ongoing exploration, drilling, and production activities. Risks to Social licence lOSS OF SOCial liCenCe TO OPeRaTe Erosion or withdrawal of community and stakeholder support, acceptance, or trust towards our business activities and operations can result from a heritage compliance breach, significant environmental incident, human rights breach, non-delivery of our decarbonisation commitments, poor community stakeholder engagement or business integrity issues. Our actions in these situations or perceived impacts on the surrounding communities, stakeholders, and broader society can lead to a loss of social legitimacy and the withdrawal of our social licence to operate. The consequences of losing our social licence to operate can include reputational damage, increased regulatory scrutiny, project delays, legal challenges, difficulty in obtaining permits or approvals, heightened operational costs, strained community relationships, and potential project shutdowns. • Internal and site-based subject matter experts to support operations in the identification and management of risks that could result in a loss of social licence to operate. • Systems and processes to support risk identification and management. • Community engagement and consultation on relevant matters. • Crisis management plans, teams and exercises. • Heritage management plans. • Consistent interface with Traditional Owner groups. • Membership of relevant industry bodies.

Critical risks include fall of ground, hazardous energy, working at height, confined space, mobile plant, equipment and vehicles, lifting operations, hazardous substances, explosives, fire and hazardous workplace exposures. Failure to manage critical risks and principal mining hazards may also result in fatality of one or more workers, also resulting in operational disruption, legal liability and reputation damage. aSSeT PeRFORManCe Loss of predictable performance at our assets will prevent us from reliably delivering on our operational targets relating to production and cost, e.g. due to production losses from fixed plant failure. This may result in increased costs and reduced mine life leading to missed market guidance, financial loss and reputation damage. • Group Health & Safety Management System (eg. training, hazard identification, emergency preparedness). • Enhancements to Critical Risk Standards & implementation of a critical risk controls verification system to manage fatality risk. • Mine planning, reconciliation and grade control plans implemented. • Asset Management System, including asset management standards and audits against these. • Maintenance program. • Technical and operational capability is maintained as a priority. Improvements to Work Management System. • SiGniFiCanT anD/OR SUSTaineD BUSineSS DiSRUPTiOn evenT • Emergency and crisis management plans, There are a variety of events that have the potential to cause significant disruption to business operations and/or ability to produce gold and meet production targets such as major fixed plant failure, natural disasters and extreme weather, pandemics, tailings storage facility failure, pit wall failure, loss of IT/OT, terrorist attack or fire resulting in loss of access to site or corporate office. An event/s of this nature could lead to financial loss, harm to people, the environment and reputation damage. eFFeCTS OF CliMaTe CHanGe We are exposed to the physical impacts of climate change, including both acute physical risks (such as risks resulting from increased frequency and/or severity of extreme weather events, such as flood, drought and bush fire events) and chronic physical risks (including risks resulting from longer term changes in climate, such as changes in precipitation patterns, water shortages, rising sea levels and sustained higher temperatures). Examples of impacts on our operations include altered water availability triggering flooding or groundwater scarcity, extreme heat days/ heatwaves, increasing prevalence and severity of cyclones and bushfires/ wildfires and increased dust generation. Left unmanaged, physical impacts of climate change could threaten sustainable long-term objectives through impacts on the integrity and performance of equipment and infrastructure, productivity, business continuity and disruption to the inbound and outbound supply chain, any of which could have a material adverse effect on our financial condition and operating results. aTTRaCTiOn & ReTenTiOn OF SKilleD PeRSOnnel The success of our business, operations and development projects depends on its ability to attract and retain personnel with the requisite skills, experience and qualifications or capacity to be trained and upskilled. A shortage of skilled labour, remote work locations, housing shortages, a trend of people preferring to work in ‘cleaner, greener’ industries, industry incidents of sexual assault, sexual harassment and bullying, trend of people preferring flexible and hybrid working may inhibit our ability to hire and retain skilled and unskilled personnel leading to capacity and capability dilution. teams and exercises. • Availability of critical spares. • Business disruption insurance. • Bi-annual climate change risk assessments which are aligned with the UN Task Force on Climate-Related Financial Disclosures (TCFD) recommendations. • Reporting to, and oversight by, the Environmental, Social & Safety Committee on climate change-related risk. • Emergency management plans, teams and exercises. Further information on key environmental and social performance risks are detailed in our latest FY23 Sustainability Report available on our website at www.nsrltd.com/sustainability/. • Competitive remuneration and benefits. • Provision of leadership and talent development programs across the business. • STARR Actions values program implemented to address results of latest Culture Survey. • Focus on global talent recruitment and mobilisation. • Organisation-wide Respect in Action training and proactive education program delivered at each site to address sexual harassment risk factors, behaviours and responses. Risks to Operational Performance SUPPlY CHain DiSRUPTiOn There is a significant reliance on the supply of goods and services to enable the delivery of operations and development projects. Supply chain disruption can arise from natural disasters, pandemic outbreaks, disruption to energy supply, cyber attack, geopolitical events and accidents. Disruption to supply may result in schedule delays, operational disruption and increased costs. SiGniFiCanT CYBeR aTTaCK Our operations are supported by and dependent upon information technology and operational technology systems consisting of infrastructure, networks and applications to monitor and control physical processes, devices and service providers. We could be subject to data breaches, network and systems interference or production disruptions resulting from a cyber attack. The threat from cyber attacks causing business disruption is ongoing. The risk is increasing given the increasing reliance on technology, increasing the attack surface and increasing interconnectivity of operational systems and data with corporate systems. Further, as systems and data continue to move into the cloud, reliance is increased on third parties to keep data secure. A significant cyber attack could result in operational disruption, financial loss, inappropriate disclosure of information and reputation damage. • Regular and early contact with suppliers made to identify and address anticipated delays or suspension in supply. • Implementation of a Supplier Relationship Management Framework. • Security Operations Centre monitors all security incidents and escalates as necessary. • Technical controls deployed, e.g. firewalls, advanced threat protection, anti-virus, anti- malware. • Cyber Security Specialist appointed to drive implementation of Cyber Security Strategy. • Cyber training delivered organisation-wide, including to senior leadership and Board. • Review of Personally Identifiable Information undertaken, with data collection, storage and sharing requirements confirmed. • Ongoing phishing exercises conducted. • Disaster recovery testing and crisis management training, including cyber attack scenarios. inDUSTRial RelaTiOnS • Engage external employment relations lawyers We may be impacted by industrial relations issues in connection with our employees and the employees of contractors and suppliers, including strikes, work stoppages, work slowdowns, grievances, complaints, and claims of unfair practices or other industrial activity. Any such activity, which could occur at any of our sites in any locations, could cause production delays, increased labour costs and adversely impact our ability to deliver on production forecasts. No industrial action has been experienced to date since we first acquired a production asset in 2010; we remain ready to engage as required. wORKPlaCe CUlTURe Workplace culture is defined by the shared set of attitudes and values held by a Company’s employees. It is influenced by an organisation’s design, including the systems, policies and procedures that enable shared beliefs to form. The culture of a workplace impacts the behaviour of employees.

NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 OPeRaTinG anD FinanCial Review Cyber Security - further comments on key strategic risk In FY23 Northern Star placed a particular focus on strengthening action to address the increasing cyber security risks faced by many organisations. We continue to place an emphasis on continuous improvement in our cyber security programs. These initiatives during FY23 include the following: • Cyber Security Specialist This appointment lifts the cyber security capabilities and governance at Northern Star. Core priorities include reviewing the current state of cyber security, determining cyber security strategy and priorities, implementing new or enhanced programs, and ensuring that there is a risk-based approach to selecting and implementing future cyber security solutions, and ensuring that third-party providers of security solutions are fit for purpose and provide adequate cyber security protections. • Review of Personally Identifiable Information (PII) Northern Star has been reviewing the collection, retention, and storage of sensitive data including PII, and challenging previous assumptions about what data needs to be collected and retained. This review is reducing the amount of PII stored on our systems and will tighten access controls and data retention periods. • Updated Cyber Security Training Program A newly developed cyber security awareness training course was introduced in FY23, with annual refresher training for all employees. The objective of the training is to make employees more cyber aware and develop cyber safe behaviours which can be applied both at the workplace and at home. The program also aims to encourage users to report all suspicious activity to the Information Technology (IT) team. The training for high-risk users includes additional information about PII, potential risks to the Company, mitigating risks, and the obligations on each of our employees to protect PII and report cyber security incidents. Financial risk related to climate change In FY23 Northern Star worked with Foresight Consulting Group to develop a climate risk financial quantification model. The model is designed to assist the business to better understand the potential financial impacts that climate-related risks could have on the Company’s operational effectiveness and financial position. Details on the development of the financial quantification model can be found in our FY23 Sustainability Report at https://www. nsrltd.com/sustainability/. • Supply Chain Cyber Security Supply chain cyber security compromise is a significant risk given the increasing dependence on technology systems by all of our suppliers. To address this risk, all new and renewing third party providers of IT hardware and software services to Northern Star are required to complete a Cyber Security Supply Chain questionnaire, with results analysed to determine if risk controls are in line with our cyber security requirements. During FY24 we intend to extend this Cyber Security Supply Chain Questionnaire to all key suppliers. • Security Operations Centre (SOC) We employ a Security Operations Centre (SOC) to collect and analyse all security events for all key systems and detect abnormal behaviour such as logins from unusual locations, unusual times, and sharing, accessing, or copying sensitive data. The SOC continues to evolve as it collects data from additional systems and new detection patterns are implemented. • Crisis Management & Disaster Recovery Testing We regularly conduct Crisis Management Training sessions for senior staff and managers across our business, and at a recent training session we tested a sophisticated cyber attack scenario. Our Crisis Management Plan was used successfully to manage the cyber security incident and included individuals from all areas of the business, including legal, human resources, finance, operational technology, site management, and senior management representatives. The IT team also successfully conducted an annual Disaster Recovery (DR) test. • Operational Technology (OT) We completed a risk review of our OT systems with the assistance of an external specialist. The findings from the review will be used to further enhance our risk controls and training programs. The exercise highlighted that Northern Star’s current decarbonisation roadmap and existing mine planning and engineering controls mitigate some of the potential financial impact associated with emissions management and key physical risks of climate change. It is reassuring to have our current risk management practices shown to be effectively managing potential risk. 42 John Kasuku, Finance Manager - NSMS, Corporate Office, Subiaco.

Some feedback was provided on some matters for improvement such as opportunities for discussions and structured time with management outside the Boardroom. 57 Shays Muthiah, Metallurgist, Jundee processing plant, Yandal. NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 DiRECTORS' REpORT DiRECTORS' REpORT Board Skills Matrix Northern Star considers that an optimal balance and diversity of skills, experience and expertise represented on the Board is essential to its effectiveness. Northern Star is committed to reviewing its skills matrix annually, to ensure the Board continues to have an appropriate mix of skills and experience and to identify any potential emerging gaps to inform succession planning. The Board skills matrix was reviewed in FY23. The skills to be measured against were chosen by the Board using a combination of the FY22 skills measured against, and additional skills suggested by external governance specialists engaged for the FY23 review. The final 27 skills categories were chosen based on the Company’s nature and scale, industry, locations of operations, workforce, operations and business strategy. Each Director self- assessed their skills and experience using a four-tier scale Figure 2 FY23 Director Experience Key Expert Advanced (from ‘Limited’, ‘General’, ‘Advanced’, to ‘Expert’) across the 27 skills categories. The FY23 Board skills assessment demonstrated the Board’s extensive skills, capability and experience in leadership, strategy, corporate governance, people & culture, remuneration and mergers & acquisitions. The Board regularly accesses specialist internal expertise and external advisers in these areas where the Board has less direct skills and experience. Overall, the assessment indicated an appropriate diversity of skills, knowledge and experience is represented on the Northern Star Board. See below the results of the Board skills matrix for FY23. The Directors who rated themselves as either ‘Expert’ or ‘Advanced’ for the relevant skill or experience are shown in coloured chart segments (out of 8), and those who rated themselves as either ‘General’ or ‘Limited’ are indicated in grey. 58 Sector understanding International experience Senior management experience Corporate governance experience Strategy oversight Experience in industry / sector (key competitors, major transactions, sector-based regulation) 3 of 8 3 of 8 Experience as a director or senior executive in strategically relevant offshore jurisdictions 5 of 8 Experience in a senior role with industry level influence or track record of long-term value creation 4 of 8 3 of 8 Board/committee experience (corporate governance, director's duties, continuous disclosure) 2 of 8 5 of 8 Experience with strategic process, capital allocation, translating strategy to business plans/budgets 2 of 8 5 of 8 Figure 3 FY23 Director Skills Key Expert Extensive practical experience and senior-level oversight in this area Advanced Strong understanding of the oversight in this area built on relevant practical experience Close involvement in evaluating major investment proposals Projects, Mergers & Acquisitions Experience with environmental management (regulation, industry best practice, EMS) ESG & Engagement Environment 3 of 8 Safety oversight Sustainability Community engagement Experience with safety reporting, safety culture, root cause analysis, safety KPIs 3 of 8 Experience with sustainability (decarbonisation, human rights, community, social responsibility) 6 of 8 Experience with community engagement (social responsibility, heritage/cultural management) 5 of 8 Experience with investor relations (investment narrative & comms, proxy advisor engagement) Investor engagement 1 of 8 4 of 8 Communications & corporate affairs Government engagement Regulatory engagement Experience with internal communications, reputation management, crisis management 6 of 8 Experience with government relations (political, policy process, key government relationships) 2 of 8 Experience with regulatory process (proactive regulatory engagement with key decision makers) 2 of 8 Experience setting remuneration frameworks, short/long term incentives, external engagement Remuneration 4 of 8 1 of 8 59 Leadership & Culture Talent & leadership Culture Experience with leadership development, succession planning, talent management 4 of 8 1 of 8 Experience with organisational culture (measurement, reporting, intervention) 4 of 8 2 of 8 Experience with significant D&I initiatives (measurement, reporting, intervention, advocacy) Diversity & inclusion 1 of 8 5 of 8 Financial & Legal Acumen Accounting & Financial Reporting Experience with external & internal audit, financial statements, financial control/systems/processes 2 of 8 4 of 8 Experience in relevant legal settings (company's legal framework, legal negotiation, class actions) Major project investment analysis Major project implementation Mergers & acquisitions Major change & transformation 3 of 8 4 of 8 Legal 1 of 8 Experience with significant major projects, project-based governance and risk management 3 of 8 1 of 8 Innovation, Digital & Technology Significant M&A experience (investment analysis, transaction structuring, deal execution, integration) Experience with significant disruption and industry transformation 4 of 8 2 of 8 Innovation & disruption 1 of 8 1 of 8 Experience with transformation and major change (strategy, implementation, vendor management) Experience with digital strategy and transformation 2 of 8 3 of 8 Digital 2 of 8 Understanding of debt/equity markets in the context of M&A activity / capital projects funding Markets 3 of 8 3 of 8 Experience with relevant industry technology, privacy, data regulation and cybersecurity risks Technology & data 2 of 8 NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 DiRECTORS' REpORT DiRECTORS' REpORT Review of operations Dividends paid in FY23 and FY22 proceedings on behalf of the Company Non-audit services 60 A review of the operations and financial position of the Group and its business strategies and prospects is set out in the Operating and Financial Review on pages 17 to 42. principal activities In FY23 the principal activities of the Group were: FY23 $'000 FY22 $'000 FY22 final dividend of 11.5 cents per fully paid Share (FY21: 9.5 cents)14 $133,986 $110,637 FY23 interim dividend of 11.0 cents per fully paid Share (FY22: 10.0 cents)15 $126,491 $116,448 • exploration, development, mining and processing of Total gold deposits and sale of refined gold derived from the: $260,477 $227,085 - Kalgoorlie Production Centre in Western Australia; Dividends recommended and to be paid - Yandal Production Centre in Western Australia; and - Pogo Production Centre in Alaska; and • exploration of gold deposits in Western Australia, the Northern Territory and Alaska.

The Group is not aware of any material breach of environmental legislation and regulations applicable to the Company’s operations during FY23. A notification of breach was received in 2021, following inspections during 2019 and 2021 by the United States Environmental Protection Agency (EPA) at our Pogo Operations. Northern Star received notification that several waste streams at the assay laboratory in the Pogo processing plant were not determined, registered and managed according to Resource Conservation and Recovery Act (RCRA) technical requirements. While this did not result in any negative impact on or damage to the environment, the breach of RCRA resulted in the EPA citing Northern Star (Pogo) LLC for 81 violations of RCRA and imposing financial penalties of US$600,000 in FY23 for “improper storage, treatment, and disposal of hazardous materials” at Pogo. Northern Star has taken steps to enhance its current training in RCRA compliance to address any gaps identified to meet RCRA requirements. The Group continues to comply with environmental regulations in all material respects.

NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 Remuneration Report RemuneRaTIOn RePORT RemuneRaTIOn RePORT Letter from the Chair of the People & Culture Committee Dear shareholder, On behalf of the Board of Directors of Northern Star Resources Ltd, I am pleased to provide to you the Remuneration Report for the financial year ending 30 June 2023. Northern Star is in a strong position, with gold sold of 1.56 million ounces in FY23 generating cash earnings of over $1.2 billion. At 30 June 2023 we held net cash of $362 million and liquidity of $2.2 billion, all underpinned by a solid platform of 57.4 million ounces of Mineral Resources and 20.2 million ounces of Ore Reserves. Interim and final dividends paid to our shareholders during FY23 totalled $261 million including dividends reinvested under our Dividend Reinvestment Plan, whilst the inaugural share buy back announced in September 2022 returned another $127 million to our shareholders. We are proud of the strong platform we have built on which to achieve our Purpose – to generate superior shareholder returns, and deliver our five year growth strategy in FY26, targeting 2Mozpa production. 64 Native flora, Pogo, Alaska. FY23 Remuneration Outcomes – FY23 STI performance rights – 29.8% result The Company’s FY23 short term incentive (STI) Performance Rights were measured as at 30 June 2023, following a one year performance period, achieving a 29.8% outcome. With Total Recordable Injury Frequency Rate at 3.2 well below industry average, by maintaining a strong safety culture and leveraging our maturing systems, we have again delivered enviable operational performance safely and responsibly in FY23. We are incredibly proud of our safety performance, which is clear evidence of ongoing improvement, consistent with the STARR Core Values. This was achieved during FY23 in the context of: • enlarged Group operations and the sheer number of worker hours involved in our underground, open pit and processing operations; • project expansion and shutdown work; and • labour market pressures, continuing our reliance on extraordinarily higher percentages of new and inexperienced starters. The 82% result for participation in the FY23 culture survey and the employee engagement score of 65% were excellent outcomes for the combined Group. We will continue to address feedback we received during the culture survey, and our efforts will continue to focus on and reinforce each of the STARR Core Values. Alignment to our STARR Core Values guides our discretionary behaviour and how we do things at Northern Star. That ultimately shapes our unique and very successful culture. Gold sales were delivered inside Group guidance; and we delivered financial management inside our revised cost guidance. Original cost guidance however was not met, and the People & Culture Committee did not recommend that the Board exercise discretion to alter the measured outcome for the FY23 STI. Similarly since gold sales were achieved at the lower end of guidance, consequently the FY23 STI has rewarded for delivered outcomes, but is not reflective of the significant efforts across all operations and by all our highly valued employees. FY23 Remuneration Outcomes – FY21 LTI performance rights – 75.4% result The Company’s FY21 long term incentive (LTI) Performance Rights were measured as at 30 June 2023, following a three year performance period, achieving an outcome of 75.4%. Results for the FY21 LTI key performance indicators are shown in Table 11 on page 78. Pleasingly we achieved a 20% increase in Ore Reserves per share, well above the KPI, a 9.4 million ounces increase. Half of the vested FY21 LTI is subject to a service condition and a holding lock for 12 months until 30 June 2024. No discretion was applied by the Board to adjust the FY23 STI or FY21 LTI outcomes for the performance measures or to change the holding lock and service condition applicable to the Executive KMP. FY24 STI awards – performance measures In the FY24 STI performance measures, the Board has continued the 50% weighting on gold sales, recognising that the biggest lever to reducing all in sustaining unit costs is by increasing gold sales. Increased gold sales is also aligned to our longer term objective of being a 2Moz pa producer and generates better cash margins. The safety weighting of 20% also remains in place for TRIFR. The Board has this year introduced a performance measure with a weighting of 10% requiring satisfactory progress on growth projects including the KCGM expansion project. FY24 LTI awards – performance measures Consistent with the FY22 and FY23 LTI awards, the FY24 LTI performance rights are subject to a four year measurement period. The performance measures for the FY24 LTI awards comprise: • • relative total shareholder return against a specific gold peer group, (40% weighting); relative total shareholder return against the Global Gold Index peer group, (40% weighting); and • Demonstrate tangible, sustainable Scope 1 and Scope 2 carbon Emissions Reductions of 200 kt CO2-e between 1 July 2021 and 30 June 2027. FY24 Remuneration No changes have been made to fixed and variable remuneration for the KMP, and the cash Board fees remain unchanged. The Committee considers that the FY24 remuneration framework ensures there is effective alignment between shareholder wealth creation, performance and reward, taking into account the size and scope of the Company’s operations. The Board is confident that the FY24 remuneration structure is appropriate to incentivise, reward and retain the high performing team at Northern Star, and geared to achieving our Purpose and strategic growth objectives consistent with our carbon emissions reductions pathways. On behalf of the Board, your continued support as a shareholder is greatly appreciated.

A copy of the People & Culture Committee Charter is available on the Corporate Governance page of the Company’s website at https://www.nsrltd.com/about/ corporate-governance. The Board has established a People & Culture Committee: • chaired by independent Non-Executive Director, Nick Cernotta; and • including other members who are independent Non-Executive Directors: Michael Chaney AO, John Fitzgerald, Sally Langer and Sharon Warburton. In FY23, the role of the People & Culture Committee was to review and make recommendations to the Board in relation to Executive KMP and other executives in respect of: • culture; • • talent management; remuneration and incentive policy including framework, practices, and quantum; • determining the eligibility, award and vesting of short term incentives (STI) and long term incentives (LTI); • Non-Executive Director individual remuneration, and the aggregate pool for approval by shareholders (as required); • disclosure of remuneration in the Company’s public materials including ASX releases and the Annual Report; • superannuation arrangements; • overseeing remuneration equity by gender and other diversity measures; • leadership development; and • other matters referred to the Committee by the Board. The Committee meets several times a year as required to review and make recommendations to the Board in accordance with the People & Culture Committee Charter, to ensure that Executive KMP remuneration remains aligned to business needs and performance and to ensure that equity plans are appropriate for all employees. The Managing Director & CEO and other Non-Executive Directors have a standing invitation to attend all or part of People & Culture Committee meetings as required (with approval of the Chair), but do not participate in recommendations by the Committee to the Board. The Managing Director & CEO is not present during any part of a meeting in which there is discussion or decisions made regarding his remuneration. From time to time, advice and recommendations are sought from remuneration consultants observing the following protocols: • • remuneration consultants are engaged by and report directly to the People & Culture Committee; the Committee must, in deciding whether to approve any remuneration consultant engagement, have regard to any potential conflicts of interest including factors that may influence independence such as previous and future work performed by the adviser and any relationships that exist between any Executive KMP and the consultant; and • communication between the remuneration consultants and Executive KMP is restricted to minimise the risk of any allegations of undue influence on the remuneration consultant. The Board makes its remuneration-related decisions after considering the recommendations of the People & Culture Committee and any advice from remuneration consultants. No remuneration recommendations (within the meaning of the Corporations Act) were sought or provided during FY23. The advisory vote to adopt the FY22 Remuneration Report was passed by 96% of shares voted at the Company’s Annual General Meeting held on 16 November 2022. 70 executive KmP remuneration practices The Company's Executive KMP remuneration practices support our Purpose: To generate superior returns for our shareholders while providing positive benefits for our stakeholders, through operational effectiveness, exploration and active portfolio management. Table 2 FY23 remuneration framework Objective Remuneration practices aligned with objective Retain our talented leadership team • Provide total remuneration opportunities that are competitive with the resources industry labour market to retain our proven, experienced, high performing and cohesive leadership team who are global company poaching targets. • Provide remuneration that is internally fair and benchmarked against a relevant peer group on an appropriate basis. Drive shareholder value creation • A significant proportion of remuneration is ‘at-risk’ variable remuneration delivered in Performance Rights and Conditional Retention Rights, to maintain management focus on delivering the Company’s strategic objectives: - Managing Director & CEO - Chief Operating Officer - Chief Financial Officer and Chief Legal Officer 80% at risk 78% at risk 72% at risk • Performance metrics are measured against ambitious targets that align Executive KMP reward with the creation of both short term and longer term value for shareholders, consistent with our business strategy. • FY23 LTI is heavily weighted (80%) towards Relative Total Shareholder Returns (RTSR) against an appropriate group of ASX and international peers and a global gold index. Focus on safety outcomes • Stretch safety performance metrics based on injury frequency rates (employee and contractors), requiring sustained industry-leading outcomes and year on year improvements, to maintain consistent management focus on ensuring the safety of our workers near and longer term. • No fatality gateway for STI & LTI safety metrics. Focus on costs and production performance • FY23 STI is heavily weighted (70%) towards delivery within guidance of: - challenging annual gold sales targets, to drive stronger financial returns for shareholders; and - All-In Sustaining Costs (AISC), to reinforce responsible operational and capital expenditure. 71 Focus on creating a desirable Company culture • FY23 STI includes two KPIs linked to the Company’s annual culture survey (participation and engagement score), to promote improvements in organisational culture across all sites and the attraction and retention of a diverse and inclusive workforce in line with the STARR Core Values.1 • Prioritise attraction, development and retention of our people to ensure a sustainable pipeline of leadership, talent and diversity within the business. Focused on positive ESG outcomes • Annual STI grant includes a KPI requiring nil heritage, community or environmental incidents, to focus management on delivering consistent, socially responsible business practices and performance with positive ESG outcomes for our stakeholders, and the communities in which we operate. • Annual LTI grant incentivises the Company’s achievement of year on year absolute reduction in greenhouse gas emissions (against a 1 July 2021 business as usual baseline) to be maintained on a consistent / sustainable basis. Downward adjustment of awards and vesting, where warranted • The Board retains discretion to: - apply malus to reduce unvested awards; - adjust vesting outcomes; and - clawback previously vested awards within two years of being delivered in Shares, in instances of significant negligence, non-compliance or other harmful act by the individual, or where absent such discretion retention of vested awards would be grossly unjustifiable. • The Board reduced unvested awards during FY22 for misconduct reasons, in relation to former employees, but there was no such discretion applied in FY23 or in relation to FY23 awards or vesting outcomes. 1. Our STARR Core Values are: Safety, Teamwork, Accountability, Respect, Results. NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 RemuneRaTIOn RePORT RemuneRaTIOn RePORT executive KmP FY23 remuneration framework Executive KMP remuneration has a fixed component (base salary plus superannuation and benefits), and a variable component (incentive and retention grants) designed to reward for achievement of strategic objectives aligned with shareholders’ interests. Remuneration mix is weighted towards the variable component, which for FY23 represented between 72% and 80% of the Executive KMP's total remuneration opportunity. Fixed annual Remuneration (FaR) Short Term Incentive (STI) Long Term Incentive (LTI) Conditional Retention Rights (CRR) PURPOSE PURPOSE PURPOSE PURPOSE Fixed annual remuneration (FAR) is aimed at providing a base level of remuneration appropriate for the particular role and level of responsibility, delivered at a level that is competitive in the market. Short term incentives (STI) provide an incentive to reward high-performing employees for achievement of a balanced scorecard of key financial and non-financial Company performance measures over a period of one year. DELIVERY METHOD • Cash salary • Superannuation capped at $27,500 per annum • Other employee benefits and entitlements2 DELIVERY METHOD • 50% Cash and 50% Performance Rights; or option to elect 100% Performance Rights (at grant) • Option to elect 100% Cash settlement (prior to vesting) • Dividend Equivalent in vested performance rights OPPORTUNITY OPPORTUNITY • FAR is periodically reviewed and benchmarked against Target STI opportunity is calculated as a percentage of FAR ASX100 and mining industry peers • • 100% of FAR for the Managing Director & CEO 100% of FAR for the Chief Operating Officer • 75% of FAR for the other Executive KMP Long term incentives (LTI) focus the senior leadership team on drivers of shareholder value over a period of four years.

The percentage opportunity is set by the Board according to the role performed and experience held by each of the Executive KMP. Note the quantum of FY23 Conditional Retention Rights was rounded to the nearest 10,000. The maximum possible total value of the Performance Rights is the assessed fair value at the grant dates of the Performance Rights, calculated in accordance with Accounting Standards, multiplied by the number of Performance Rights granted.

The Company issues long term and short term incentives and conditional retention incentives as Performance Rights under this Plan, using a face value allocation methodology. Incentivising the Company’s high-performing team is the essential link between senior management remuneration, the Company’s performance and delivery of long-term sustainable shareholder value. A copy of the FY20 Share Plan is available free of charge at the Company’s Registered Office and upon request from the Company Secretary at compliance@nsrltd.com. element Purpose Provisions The main objectives of the Plan are to create a stronger link between performance and longer-term remuneration outcomes for those who participate in the Plan (Participants) and allow Participants to share in the future growth and profitability of the Company. Eligible Employees Broadly, any full or part-time employee (including an executive director) of the Company or a subsidiary (Group Employee) who has not given a notice of resignation or been given a notice of termination of employment is eligible. Non-Executive Directors are not eligible to participate. Administration of the Plan The Plan will be administered by the People & Culture Committee under the directions of the Board. The Board may delegate its powers and discretions, determine procedures for the administration of the Plan, and resolve questions of interpretation and disputes in relation to the Plan. Invitations The Board may issue Invitations to Eligible Employees to be granted Awards under the Plan. The terms and conditions in the Invitation will prevail to the extent of any inconsistency with the FY20 Share Plan rules. For Group Employees, the measurable objectives, the weighting amongst them and the performance periods during which time they are required to be met, are set by the Board annually in relation to the Executive KMP, and by the CEO annually in relation to other senior management employees, for the short term incentives and long term incentives for each year in which Awards are granted under the Plan. 96 Awards Awards will consist of grants of Performance Rights, Conditional Retention Rights or other conditional rights to be delivered a Share on the vesting of the Participant's Performance Rights or Conditional Retention Rights. No Transfer A Performance Right or a Conditional Retention Right may not be transferred without the prior written approval of the Board. Vesting Conditions Awards will be subject to Vesting Conditions. Vesting Conditions are to be determined by the Board and described in the Invitation and will include performance conditions set by the Board. The Board may waive, replace or amend a Vesting Condition, for example, if the Board determines that the original performance measure is no longer appropriate, practical or applicable. Vesting of Awards Awards will vest if and when the Board determines that the Vesting Conditions are satisfied and the Participant is notified of this in writing. Delivery of Shares Following vesting of a Share Right, the Participant will be entitled to delivery of a Share upon exercising the Share Right. Awards that vest are normally exercisable up until the tenth anniversary of the date of grant of the Awards (although shorter periods will apply if the Participant ceases to be employed). The Board will determine how the Shares are to be delivered, which may be by issue of new Shares to, purchase and transfer to, or procuring Shares to be held for the benefit of (i.e. through the Company’s Employee Share Trust), the relevant Participant, or a combination of such methods of delivery. Alternatively, the Board may determine to settle in cash in lieu of delivering Shares. The cash payment would be based on the volume weighted average price of Shares in the 20 ASX trading days prior to the date of exercise. Ranking of Shares Any Shares delivered to a Participant when an Award is exercised will rank equally with all other issued Shares. Restricted Shares Invitations may specify that Shares delivered on vesting cannot be disposed of for a specified period following delivery. Expiry Vested Performance Rights and Conditional Retention Rights automatically lapse on the tenth anniversary of their grant date. Performance Rights and Conditional Retention Rights held by a former employee of the Group that: • had already vested when the employee ceased – expire 12 months after the employee’s end date; or • vest after the employee's end date – expire 6 months after the relevant vesting date. element Provisions Termination of employment Malus and Clawback The Invitation will specify the consequences of cessation of employment during a performance period, depending on the reasons, and subject to Board discretion. For example, where employment ends because of agreed mutual separation, the proportion of the unvested Performance Rights or Conditional Retention Rights which is the same as the proportion of the relevant performance period during which the Participant was employed, may or may not lapse according to Board discretion, and the balance of the Performance Rights or Conditional Retention Rights will lapse on cessation, unless the Board exercises discretion otherwise. The Board may reduce unvested Awards, and clawback previously vested Awards from a Participant or former Participant within two years from the date of delivery of Shares (or receipt of cash paid in lieu of delivering Shares). The Board may exercise this power having regard to matters it considers relevant acting in good faith in the interests of the Company. The Board intends for this power to be exercised in instances of: • material financial misstatements; • significant negligence; • significant legal, regulatory and/or policy non-compliance; • significant harmful act by the individual; or • the Board holding the opinion that the Participant received or would receive a grossly unjustifiable benefit because of factors outside the Participant’s control. No participation rights Performance Rights and Conditional Retention Rights do not entitle the holder to participate in a new issue of Shares or other securities, or the right to any dividends or distributions paid on Shares. 97 Control transactions If a control event occurs: • the proportion of the unvested Performance Rights or Conditional Retention Rights of each Participant which is the same as the proportion of the relevant performance period that has expired before the date of the control event (determined by the Board) will vest immediately (regardless of the status of the Vesting Conditions, without limiting the Board’s ability to exercise downward discretion if circumstances warrant this); and • the balance of the Performance Rights or Conditional Retention Rights will vest or lapse on that date, as the Board determines in its discretion. A "control event" includes: a takeover bid where the bidder has acquired a relevant interest in more than 50% of the Shares and either the Board has recommended the bid or the bid has become unconditional; court approval of a scheme of arrangement which will result in a person having a relevant interest in more than 50% of the Shares; or another event which the Board declares to be a control event. Amendment The Board may amend the Plan. However, the Participant's consent is required for amendments to the Plan that reduce the rights of the Participant in respect of an Award that has already been granted (other than for legal reasons, correcting manifest errors/mistakes or tax reasons). Operation The operation of the Plan is subject to the Company's Constitution, the ASX Listing Rules, the Corporations Act and other applicable laws. Board Discretion The Board retains absolute discretion to vary Awards or the application of the rules of the Plan, and to exercise or refrain from exercising any power or discretion under the FY20 Share Plan rules.

These changes are accumulated within the FVOCI reserve within equity as described at note 24(e) Investments and other financial assets. The Group transfers amounts from this reserve to retained earnings when the relevant equity securities are derecognised. Share based payments The share based payments reserve relates to shares, performance shares, performance rights and share options granted by the Company to its employees. Further information about share based payments to employees is set out in note 20. The increase in share based payment reserve and expense for services rendered by employees during the period is determined with reference to the grant date fair value of the applicable award. The tax benefit, where available, in respect of those awards is made with reference to the share price at the time the underlying shares are acquired or issued by the Group to satisfy those awards. Where the tax benefit available is in excess of the tax effect on the cumulative charge to profit and loss, the remaining credit is determined to relate to the equity issue and is included within the share based payment reserve. Amounts recorded in the share based payment reserve are reclassified to contributed equity on vesting of the performance rights. During FY23, nil (2022: $0.5 million) was transferred from the share based payment reserve to contributed equity in relation to tax benefits on respective awards. Foreign currency translation Exchange differences arising on translation of the foreign controlled entities are recognised in other comprehensive income and accumulated in a separate reserve within equity. The cumulative amount is reclassified to profit or loss when the net investment is disposed of. Exchange differences arising from net investment hedges are also recorded within the foreign currency translation reserve. Cash flow hedge reserve The cash flow hedge reserve is used to recognise the effective portion of gains or losses on derivatives that are designated and qualify as cash flow hedges. 107 The above Consolidated Statement of Changes in Equity should be read in conjunction with the accompanying notes.

The information on Mineral Resources and Ore Reserves is prepared by Competent Persons as defined by the JORC Code. There are numerous uncertainties inherent in estimating Mineral Resources and Ore Reserves. Assumptions that are valid at the time of estimation may change significantly when new information becomes available. Changes in the forecast prices of commodities, exchange rates, production costs or recovery rates may change the economic status of reserves and may, ultimately, result in the reserves being restated. Such changes may impact asset carrying values, depreciation and amortisation rates, deferred development costs and provisions for restoration. Other critical accounting judgements, estimates and assumptions are discussed in the following notes: Unit of production method of depreciation/amortisation Exploration and evaluation expenditure Mine rehabilitation provision Impairment of assets Life of component ratio for stripping asset Share based payments Recognition of revenue Lease accounting (determination of lease term and uncertainties and judgements in relation to lease accounting) Climate change considerations note 6(a), 9(d) note 9(c) note 9(g) note 9(c) note 9(d) note 20 note 4 note 9(b) note 24(a)(v) 2 Segment information 110 The Group's Executive Committee as the Chief Operating Decision Maker consists of the Managing Director and Chief Executive Officer, Chief Financial Officer, Chief Operating Officer, Chief Technical Officer and Chief Geological Officer examine the Group's performance and have identified seven reportable segments relating to the operations of the business: (a) Description of segments and principal activities The Group's reportable operating segments are: 1.

Jundee, WA Australia - Mining and processing of gold 5. Thunderbox, WA Australia and Bronzewing, WA Australia - Mining and processing of gold 6. Carosue Dam, WA Australia - Mining and processing of gold 7. Exploration - Exploration and evaluation of gold mineralisation Segment information (a) Description of segments and principal activities (continued) An operating segment is a component of the Group that engages in business activities from which it may earn revenues or incur expenses. The Executive Committee has determined the Group to have seven operating segments (Kalgoorlie Operations, Jundee, Pogo, KCGM, Thunderbox (including Bronzewing), Carosue Dam and Exploration). As in the prior year, Kanowna Belle and South Kalgoorlie is considered as one and has been presented as one reporting segment (Kalgoorlie Operations).

The Exploration segment for the year ended 30 June 2023 included Tanami, Talisman and Bundarra. The East Kundana JV and Millennium operations were sold in the prior period. Refer to note 14(a) for more detail. The Paulsens and Western Tanami projects were sold in the prior period. Refer to note 14(b) for more detail. Where related exploration assets are transferred to mine properties from the exploration segment in the future, these will be incorporated into the relevant operating segment. Exploration comprises all projects in the exploration and evaluation phase of the Group. These include the Group's regional prospects as well as ongoing exploration programmes at the Group’s respective sites. An analysis of segment revenues is presented in note 4(a).

These cover situations where the accounting standards either allow a choice or do not deal with a particular type of transaction (b) analysis and subtotals, including segment information, and (c) information about estimates and judgements made in relation to particular items. 3 Significant changes in the current reporting period The financial position and performance of the Group was particularly affected by the following events and transactions during the reporting period: • In April 2023 the issue of the US$600M Guaranteed senior notes bearing interest of 6.125% per annum. For details refer to note 8(e) of the financial statements. • A non-cash inventory write back of $436.6 million (2022: $nil) has been recognised in relation to the previously written down sub grade inventory stockpiles at KCGM. Following the approval of the mill expansion project at KCGM in June 2023, certainty was provided regarding the processing of these stockpiles and the timing of when processing of these sub grade stockpiles will occur. As such, the previously recorded write down was reversed. For details refer to note 9(f) of the financial statements. • An A$300 million on-market share buy-back program commenced with $127.1 million (42%) completed during the financial year. For details refer to note 10(a) and note 18 of the financial statements. • Following an amendment to AASB 116 Property, Plant and Equipment, as issued by the Australian Accounting Standards Board, the Group changed its accounting policy in relation to the treatment of accounting for ounces of gold sold from a mine which is not in commercial production. The amendment prohibits entities from deducting from the cost of an item of property, plant and equipment any sales proceeds earned from selling items produced while bringing the asset to the condition necessary for it to be capable of operating in the manner intended by management. Instead such sales proceeds must be recognised in profit or loss. The financial statements have been restated as the amendment required full retrospective restatement and further details are include in note 24(b) of the financial statements. 114 4 Revenue Accounting Policy (i) Sale of goods The Group primarily generates revenue from the sale of gold and silver bullion. The Group delivers dore bars to refiners, who convert the product into investment grade bullion for a fee, which is subsequently sold either to the refinery or third parties (financial institutions). Revenue from the sale of these goods is recognised when control over the inventory has transferred to the customer. Control is generally considered to have passed when: • physical possession and inventory risk is transferred (including via a third-party transport provider arranged by the refinery): • payment terms for the sale of goods can be clearly identified through the sale of metal credits received or receivable for the transfer of control of the asset; • the Group can determine with sufficient accuracy the metal content of the goods delivered; and • the refiner has no practical ability to reject the product where it is within contractually specified limits. Revenue Revenue (continued) The Group derives the following types of revenue: Sale of gold Sale of silver Total revenue 30 June 2023 $M 4,124.2 6.9 4,131.1 30 June 2022 Restated $M 3,795.8 10.5 3,806.3 Sale of gold includes an amount of $0.5 million (2022: $4.5 million) in relation to hedge book liability unwind, which was acquired as part of the Saracen merger and has not been allocated to segments.

The fair value of shares granted under these Plans are recognised as a share based payments expense with a corresponding increase in equity. The total amount to be expensed is determined by reference to the fair value of the shares granted, which includes any market performance conditions and the impact of any non-vesting conditions, but excludes the impact of any service and non-market performance vesting conditions. Non-market vesting conditions are included in assumptions about the number of shares that are expected to vest. The total expense is recognised over the vesting period, which is the period over which all of the specified vesting conditions are to be satisfied. At the end of each period, the entity revises its estimates of the number of shares that are expected to vest based on the non-market vesting conditions. It recognises the impact of the revision to original estimates, if any, in profit or loss with a corresponding adjustment to equity. (c) Impairment of assets Depreciation/amortisation method Items of property, plant and equipment and mine properties are depreciated/amortised over their useful lives. The Group uses the unit-of-production basis when depreciating/amortising mine specific assets which results in a depreciation/amortisation charge proportional to the depletion of the anticipated remaining life of mine which is referenced to the estimated economic reserve and resources of the property to which the assets relate. Each item’s economic life, which is assessed annually has due regard to both its physical life limitations and to present assessments of economically recoverable reserves and resources of the mine property at which it is located. Depreciation of non-mine specific property, plant and equipment is calculated using the straight-line method to allocate their cost or revalued amounts, net of their residual values, over their estimated useful lives or, in the case of leasehold improvements and certain leased plant and equipment, the shorter lease term as follows: Land and buildings Plant and equipment • • • Motor Vehicles • Office equipment • Intangible assets 116 5 - 20 years 2 - 20 years 4 - 10 years 2 - 10 years 15 years Depreciation methods, useful lives and residual values are reviewed at each reporting date. The useful lives of the above assets is not expected to be significantly impacted by the Group's sustainability strategy, given its focus on moving to electricity generated by renewables. Royalties Royalties under existing royalty regimes in Australia are payable on lodgement with the refining counterparty and are recognised as the sale occurs. Production Royalties in Alaska are based on taxable profit and are consequently treated as an income tax.

The unwinding of the effect of discounting the provision is recorded as a finance charge in profit or loss. 7 Income tax expense The income tax expense for the period is the tax payable on the current period’s taxable income based on the applicable income tax rate adjusted by changes in deferred tax assets and liabilities attributable to temporary differences and to unused tax losses. The current income tax charge is calculated on the basis of the tax laws enacted or substantively enacted at the end of the reporting period in the countries where the Company’s subsidiaries operate and generate taxable income. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities. Deferred income tax is provided in full, using the liability method, on temporary differences arising between the tax bases of assets and liabilities and their carrying amounts in the consolidated financial statements. Deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Current and deferred tax is recognised in profit or loss, except to the extent that it relates to items recognised in other comprehensive income or directly in equity. In this case, the tax is also recognised in other comprehensive income or directly in equity, respectively.

Refer to note 9(d) for further information on accounting policies associated with impairment. Historical cost includes expenditure that is directly attributable to the acquisition of the items. Subsequent costs are included in the asset's carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably.

As a lessee, the Group recognises a right-of-use asset representing its right to use the underlying asset and a lease liability representing its obligation to make lease payments. An assessment is made, at inception or when contract terms are changed, to determine whether the contract is, or contains, a lease. A contract is or contains a lease if the contract conveys a right to control the use of an identified asset for a period of time in exchange for consideration. The Group assesses whether a contract is or contains a lease, at inception of the contract. The Group recognises a right-of-use asset and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, except for short-term leases (defined as leases with a lease term of 12 months or less) and leases of low value assets. For these leases, the Group recognises the lease payments as an operating expense on a straight-line basis over the term of the lease unless another systematic basis is more representative of the time pattern in which economic benefits from the leased assets are consumed. The lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the Group uses its incremental borrowing rate. Assets and liabilities arising from a lease are initially measured on a present value basis. Lease liabilities include the net present value of the following lease payments: • fixed payments (including in-substance fixed payments), less any lease incentives receivable • variable lease payment that are based on an index or a rate • amounts expected to be payable by the lessee under residual value guarantees • the exercise price of a purchase option if the lessee is reasonably certain to exercise that option, and 126 • payments of penalties for terminating the lease, if the lease term reflects the lessee exercising that option. The lease liability is subsequently measured by increasing the carrying amount to reflect interest on the lease liability (using the effective interest method) and by reducing the carrying amount to reflect the lease payments made. The Group remeasures the lease liability (and makes a corresponding adjustment to the related right-of-use asset) whenever: • The lease term has changed or there is a significant event or change in circumstances resulting in a change in the assessment of exercise of a purchase option, in which case the lease liability is remeasured by discounting the revised lease payments using a revised discount rate. • The lease payments change due to changes in an index or rate or a change in expected payment under a guaranteed residual value, in which case the lease liability is remeasured by discounting the revised lease payments using an unchanged discount rate (unless the lease payments change is due to a change in a floating interest rate, in which case a revised discount rate is used). • A lease contract is modified and the lease modification is not accounted for as a separate lease, in which case the lease liability is remeasured based on the lease term of the modified lease by discounting the revised lease payments using a revised discount rate at the effective date of the modification. The right-of-use assets comprise the initial measurement of the corresponding lease liability, lease payments made at or before the commencement date, less any lease incentives received and any initial direct costs. They are subsequently measured at cost less accumulated depreciation and impairment losses. Whenever the Group incurs an obligation for costs to dismantle and remove a leased asset, restore the site on which it is located or restore the underlying asset to the condition required by the terms and conditions of the lease, a provision is recognised and measured under AASB 137 Provisions, Contingent Liabilities and Contingent Assets. To the extent that the costs relate to a right-of-use asset, the costs are included in the related right-of-use asset, unless those costs are incurred to produce inventories. Non-financial assets and liabilities (b) Leases (continued) Right-of-use assets are depreciated over the shorter period of lease term and useful life of the underlying asset. If a lease transfers ownership of the underlying asset or the cost of the right-of-use asset reflects that the Group expects to exercise a purchase option, the related right-of-use asset is depreciated over the useful life of the underlying asset. The depreciation starts at the commencement date of the lease. The Group applies AASB 136 Impairment of Assets to determine whether a right-of-use asset is impaired and accounts for any identified impairment loss as described in the ‘Property, Plant and Equipment’ policy (as outlined in the financial report for the annual reporting period). Variable rents that do not depend on an index or rate are not included in the measurement the lease liability and the right-of-use asset. The related payments are recognised as an expense in the period in which the event or condition that triggers those payments occurs and are included in profit or loss. As a practical expedient, AASB 16 Leases permits a lessee not to separate non-lease components, and instead account for any lease and associated non-lease components as a single arrangement. The Group has not used this practical expedient. For a contracts that contain a lease component and one or more additional lease or non-lease components, the Group allocates the consideration in the contract to each lease component on the basis of the relative stand-alone price of the lease component and the aggregate stand-alone price of the non-lease components.

Exploration and evaluation expenditure is capitalised on an area of interest basis. Costs incurred before the Group has obtained the legal rights to explore an area are recognised in the statement of profit or loss and other comprehensive income. Exploration and evaluation assets are only recognised if the rights of the area of interest are current and either, the expenditures are expected to be recouped through successful development and exploitation of the area of interest or activities in the area of interest have not at the reporting date; reached a stage which permits a reasonable assessment of the existence or otherwise of economically recoverable reserves and active and significant operations in, or in relation to, the area of interest are continuing. Once a development decision has been made, all past exploration and evaluation expenditure in respect of an area of interest that has been capitalised is transferred to mine properties where it is amortised over the life of the area of interest to which it relates on a unit-of-production basis. No amortisation is charged during the exploration and evaluation phase. The application of the above accounting policy requires management to make certain estimates and assumptions as to future events and circumstances, in particular, the assessment of whether economic quantities of reserves will be found. Any such estimates and assumptions may change as new information becomes available, which may require adjustments to the carrying value of assets. Capitalised exploration and evaluation expenditure is assessed for impairment when an indicator of impairment exists, and capitalised assets are written off where required. 128 Opening balance at 1 July Expenditure for the period Acquired as part of asset acquisition (i) Transfer to mine properties Impairment (ii) Exchange differences Closing balance (i) Asset acquisition 30 June 2023 $M 30 June 2022 $M 653.5 130.4 - (59.9) (42.3) 3.3 685.0 609.3 120.5 15.0 (44.4) (52.4) 5.5 653.5 During the prior period, the Company paid $15 million to Tanami Gold NL for an additional 10% joint venture interest. Following the payment, a 50/50 joint venture covering the Central Tanami Project in the Northern Territory was completed. (ii) Impairment At each reporting date the Group undertakes an assessment of the carrying amount of its exploration and evaluation assets. During the year the Group identified indicators of impairment on certain exploration and evaluation assets under AASB 6 Exploration for and Evaluation of Mineral Resources. As a result of this review, an impairment loss of $42.3 million (2022: $52.4 million) has been recognised in the statement of profit or loss and other comprehensive income in relation to areas of interest where no future exploration and evaluation activities are expected. Accounting policy Mine properties includes aggregate expenditure in relation to mine construction, mine development, exploration and evaluation expenditure where a development decision has been made and acquired mineral interests. Expenditure incurred in constructing a mine by, or on behalf of, the Group is accumulated separately for each area of interest in which economically recoverable reserves and resources have been identified. This expenditure includes direct costs of construction, drilling costs and removal of overburden to gain access to the ore, borrowing costs capitalised during construction and an appropriate allocation of attributable overheads. Further, any revenue generated during the pre-production phase of mining is recorded in profit and loss as revenue with appropriate costs of production allocated and charged to profit or loss. Mine development represents expenditure in respect of exploration and evaluation, overburden removal based on underlying mining activities and related mining data and construction costs and development incurred by or on behalf of the Group previously accumulated and carried forward in relation to properties in which mining has now commenced. Such expenditure comprises direct costs and an appropriate allocation of directly related overhead expenditure. All expenditure incurred prior to commencement of production from each development property is carried forward to the extent to which recoupment out of future revenue from the sale of production, or from the sale of the property, is reasonably assured. When further development expenditure is incurred in respect of a mine property after commencement of commercial production, such expenditure is carried forward as part of the cost of the mine property only when future economic benefits are reasonably assured, otherwise the expenditure is classified as part of the cost of production and expensed as incurred. Such capitalised development expenditure is added to the total carrying value of mine development being amortised. Mine development costs (as transferred from exploration and evaluation and/or mines under construction) are amortised on a units-of-production basis over the life of mine to which they relate. In applying the units of production method, amortisation is calculated using the expected total contained ounces as determined by the life of mine plan specific to that mine property. For development expenditure undertaken during production, the amortisation rate is based on the ratio of total development expenditure (incurred and anticipated) over the expected total contained ounces as estimated by the relevant life of mine plan to achieve a consistent amortisation rate per ounce. The rate per ounce is typically updated annually as the life of mine plans are revised. 129 Mineral interests comprise identifiable exploration and evaluation assets, mineral resources and ore reserves, which are acquired as part of a business combination or joint venture acquisition and are recognised at fair value at the date of acquisition. Where possible, mineral interests are attributable to specific areas of interest and are classified within mine properties. Production stripping expenditure Stripping (waste removal) costs are incurred both during the development phase and production phase of operations. Stripping costs incurred during the development phase are capitalised as mines under construction. Stripping costs incurred during the production phase are generally considered to create two benefits: • • the production of ore inventory in the period - accounted for as a part of the cost of producing those ore inventories; or improved access to the ore to be mined in the future - recognised under producing mines if the following criteria are met: - - - future economic benefits (being improved access to the ore body) associated with the stripping activity are probable; the component of the ore body for which access has been improved can be accurately identified; and the costs associated with the stripping activity associated with that component can be reliably measured. NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 FInancIal RepoRt FInancIal RepoRt Non-financial assets and liabilities (d) Mine properties (continued) Production stripping expenditure (continued) The amount of stripping costs deferred is based on the life of component ratio which is obtained by dividing the amount of waste tonnes mined by the quantity of ore tonnes for each component of the mine. Stripping costs incurred in the period are deferred to the extent that the actual current period waste to ore ratio exceeds the life of component expected 'life of component' ratio. A component is defined as a specific volume of the ore body that is made more accessible by the stripping activity and is determined based on mine plans. An identified component of the ore body is typically a subset of the total ore body of the mine. Each mine may have several components, which are identified based on the mine plan. The deferred stripping asset is initially measured at cost, which is the accumulation of costs directly incurred to perform the stripping activity that improves access to the ore within an identified component, plus an allocation of directly attributable overhead costs. The deferred stripping asset is depreciated over the expected useful life of the identified component of the ore body that is made more accessible by the activity, on a units of production basis. Expected total contained ounces as determined by the life of mine plan are used to determine the expected useful life of the identified component of the ore body.

If any such indication exists, the recoverable amount of the asset is estimated to determine the extent of the impairment loss (if any) which is the amount by which the assets carrying value exceeds its recoverable amount. Where the asset does not generate cash in-flows that are independent from other assets, the Group estimates the recoverable amount of the cash-generating unit (CGU) to which the asset belongs. The recoverable amount is the higher of ‘fair value less costs of disposal’ (FVLCOD) and ‘value in use’. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted. If the recoverable amount of an asset (or CGU) is estimated to be less than its carrying amount, the carrying amount of the asset (or CGU) is reduced to its recoverable amount. An impairment loss is recognised in profit or loss immediately. Where an impairment loss subsequently reverses for assets other than goodwill, the carrying amount of the asset (or CGU) is increased to the revised estimate of its recoverable amount, but only to the extent that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or CGU) in prior years. A reversal of an impairment loss is recognised in profit or loss immediately. Impairment testing requires assets to be grouped together into the smallest group that generates cash inflows from continuing use that are largely independent of the cash inflows of other assets or cash generating units. Depending on the location of the mine and processing strategy, as well as other external factors, the CGU may include more than one operating mine with a processing facility. Non-financial assets and liabilities (d) Mine properties (continued) Estimates of quantities of recoverable minerals, production levels, operating costs and capital requirements are sourced from our planning process, including the LOM plans, five-year plans, one-year budgets and CGU-specific studies. The determination of FVLCOD for each CGU are considered to be Level 3 fair value measurements, as they are derived from valuation techniques that include inputs that are not based on observable market data. The Group considers the inputs and the valuation approach to be consistent with the approach taken by market participants. There were no indications that an asset or CGU required impairment testing at 30 June 2023.

Deferred tax assets, including those arising from unutilised tax losses (where applicable), require management to assess the likelihood that the Group will comply with the relevant tax legislation and will generate sufficient taxable earnings in future years in order to recognise and utilise those deferred tax assets. Estimates of future taxable income are based on forecast cash flows from operations and existing tax laws in each jurisdiction. These assessments require the use of estimates and assumptions such as exchange rates, commodity prices and operating performance over the life of the assets. To the extent that cash flows and taxable income differ significantly from estimates, the ability of the Group to realise the deferred tax assets reported at the reporting date could be impacted. Additionally, future changes in tax laws in the jurisdictions in which the Group operates could limit the ability of the Group to obtain tax deductions in future years. 133 (f) Inventories Accounting policy Gold bullion, gold in circuit and ore stockpiles are physically measured or estimated and valued at the lower of cost and net realisable value. Cost represents the weighted average cost and includes direct purchase costs and an appropriate portion of fixed and variable production overhead expenditure, including depreciation and amortisation, incurred in converting materials into finished goods. Inventory generated in the pre-production phase of mining includes an allocation of mining costs for open pit and underground. For further information on this see note 24(b). Materials and supplies are valued at the lower of cost and net realisable value. Any allowance for obsolescence is determined by reference to specific stock items identified. A regular and on-going review is undertaken to establish the extent of surplus items and an allowance is made for any potential loss on their disposal. Net realisable value is the estimated selling price in the ordinary course of business less the estimated costs of completion and the estimated costs necessary to make the sale. NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 FInancIal RepoRt FInancIal RepoRt Non-financial assets and liabilities (f) Inventories (continued) Non-financial assets and liabilities (g) Provisions Ore stockpiles which are not expected to be processed in the 12 months after the reporting date are classified as non-current inventory. Where there is a reasonable expectation that the processing of these stockpiles will have a future economic benefit to the Group, these stockpiles are carried at the lower of cost and net realisable value. If there is significant uncertainty as to if and/or when the stockpiled ore will be processed by the Group, the ore is expensed as mined, or otherwise, where such indications arise. The determination of the current and non-current portion of ore stockpiles includes the use of estimates and judgements about when ore stockpile draw downs for processing will occur. These estimates and judgements are based on current forecasts and mine plans and expected developments, taking in to account operating history. The initial measurement of the stockpile inventory acquired as part of the merger with Saracen Minerals Holdings Limited involved the use of significant estimates and judgements. The key assumptions employed in measuring this inventory included: forecast gold prices, processing costs, grade and thus contained metal, processing recoveries and timing of processing. The initial fair values allocated to ore stockpiles are subsequently considered their deemed cost, and any future adverse change in the significant estimates and judgements could result in a net realisable value below deemed cost.

At the time of the merger the milling capacity at KCGM was 13Mtpa and there was no certainty regarding the timing and likelihood of processing of the sub grade ore stockpiles. On 22 June 2023, the Company announced a commitment to increase the capacity at the KCGM Mill to 27Mtpa. The expansion plan provides a high degree of certainty that the sub grade stockpiles will be processed and certainty over timing of commencement of the processing. Management performed a sensitivity analysis and determined the Net Realisable Value exceeded the cost of $436.6 million, resulting in the reversal of the previously recorded $436.6 million write down. The Group has recorded the $436.6 million write back at 30 June 2023 in the profit and loss account with the corresponding impact increasing long term stockpiles. In determining the net realisable value management used significant judgements and estimates including consensus gold price assumptions, gold recovery rate, processing costs amongst others. Accounting policy Provisions are recognised when the Group has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation and the amount can be reliably estimated. Provisions are not recognised for future operating losses. Provisions are measured at the present value of management's best estimate of the expenditure required to settle the present obligation at the end of the reporting period. The discount rate used to determine the present value is a pre-tax rate that reflects current market assessments of the time value of money. Rehabilitation costs include the dismantling and removal of mining plant, equipment and building structures, waste removal and rehabilitation of the site in accordance with the requirements of the mining permits and expectations from communities. Such costs are determined using estimates of future costs, current legal requirements and technology. Rehabilitation costs are recognised in full at present value as a non-current liability. An equivalent amount is capitalised as part of the cost of the asset when an obligation arises to decommission or restore a site to a certain condition after abandonment as a result of bringing the assets to its present location. The capitalised cost is amortised over the life of the project and the provision is accreted periodically as the discounting of the liability unwinds. The unwinding of the discount is recorded as a finance cost. Any changes in the estimates for the costs or other assumptions against the cost of relevant assets are accounted for on a prospective basis. In determining the costs of site restoration there is uncertainty regarding the nature and extent of the restoration due to community expectations and future legislation.

(i) Information about individual provisions and significant estimates Rehabilitation provision The Group assesses its mine rehabilitation provision annually. Significant judgement is required in determining the provision for mine rehabilitation and closure as there are many factors that will affect the ultimate liability payable to rehabilitate the mine sites, including future disturbances caused by further development, changes in technology, changes in regulations, price increases, changes in social expectations, changes in timing of cash flows which are based on life of mine plans and changes in discount rates. When these factors change or become known in the future, such differences will impact the mine rehabilitation provision in the period in which the change becomes known. Long service leave The liability for long service leave and other long-term benefits is measured at the present value of the estimated future cash outflows to be made by the Group for all employees at the reporting date. Long-term benefits not expected to be settled within 12 months are discounted using the rates attaching to high quality corporate bonds at the reporting date, which most closely match the terms of maturity of the related liability. In determining the liability for these long-term employee benefits, consideration has been given to expected future increases in wage and salary rates, the Group’s experience with staff departures and periods of service. Related on-costs are also included in the liability.

Current year profit and loss information has been included where relevant to add further context. The Board has the overall responsibility for the establishment and oversight of the risk management framework. The Audit and Risk Committee is responsible for developing and monitoring risk management policies. The Committee reports regularly to the Board on its activities. Risk management policies are established to identify and analyse the risks faced by the Group, to set appropriate risk limits and controls, and to monitor risks and adherence to limits. Risk management policies and systems are reviewed regularly to reflect changes in market conditions and the Group’s activities. The Group, through its training and management standards and procedures, aims to develop a disciplined and constructive control environment in which all employees understand their roles and obligations. The Group’s Audit and Risk Committee oversees how management monitors compliance with the Group’s risk management policies and procedures and reviews the adequacy of the risk management framework in relation to the risks faced by the Group. (a) Market risk (i) Foreign exchange risk The Group operates internationally and is exposed to foreign exchange risk arising from foreign currency transactions, primarily with respect to the US$. Foreign exchange risk arises from future commercial transactions and recognised assets and liabilities denominated in a currency that is not the functional currency of the relevant entity. The carrying value of financial instruments that are held in a currency other than the entity's functional currency are as follows (expressed in Australian dollars): 138 Financial Assets - USD Cash and cash equivalents Trade receivables Financial Liabilities - USD Borrowings Secured asset financing Trade payables Financial Assets - CAD Cash and cash equivalents Convertible Debenture (note 8(c)) 30 June 2023 $M 643.1 - 643.1 30 June 2023 $M 905.0 166.9 7.2 1,079.1 30 June 2023 $M 4.3 180.1 184.4 30 June 2022 $M 96.2 17.3 113.5 30 June 2022 $M - 149.9 2.4 152.3 30 June 2022 $M 5.0 169.3 174.3 Financial risk management (a) Market risk (continued) (i) Foreign exchange risk (continued) Financial Assets - EUR Cash and cash equivalents 30 June 2023 $M 30 June 2022 $M 6.7 - The sensitivity of profit or loss to changes in the exchange rates arises mainly from US dollar-denominated financial instruments. A 10 percent increase in the AUD/USD, AUD/CAD, and AUD/EUR exchange rate would increase post tax profit by $15.6 million while a 10 percent decrease in the AUD/USD, AUD/CAD, and AUD/EUR exchange rate would decrease post tax profit by $19.0 million. This calculation excludes the current USD $250M Hedge, this hedge would adjust the risk and if considered a 10 percent increase in the AUD/USD, AUD/CAD, and AUD/EUR exchange rate would decrease post tax profit by $8.4 million while a 10 percent decrease in the AUD/USD, AUD/CAD, and AUD/EUR exchange rate would increase post tax profit by $10.3 million. Foreign currency forwards The Group uses foreign currency forwards to hedge its exposure to foreign currency risk. The Group has determined the fair value of the foreign currency forwards by calculating the present value of future cash flows based on observable forward exchange rates at the balance sheet date. As the forward contracts are used to hedge forecast transactions, the Group designates the full change in fair value of the forward contract as the hedging instrument and recognises the gains or losses relating to the effective portion of the change in fair value of the entire forward contract in the cash flow hedge reserve within equity. (ii) Hedging The Group uses net investment hedging to hedge its exposure to foreign currency risk. The Group has designated a net investment hedge of USD$250 million in the net assets of one of its foreign operations. Under this hedging strategy, the foreign exchange movement on USD$250 million of the newly obtained USD denominated bonds can be reclassified to the foreign currency translation reserve. This occurs at each balance date and hedges the revaluation of the net assets of the foreign operation which were designated as part of the hedging relationship at inception. This reduces the impact on the profit and loss account of foreign exchange volatility each period. (iii) Cash flow and fair value interest rate risk The Group is exposed to interest rate risk through its longer term borrowings comprising a $500 million facility maturing 30 June 2024 and $500 million facility maturing 30 June 2025. At 30 June 2023, the Group was undrawn from these facilities. The Group is currently not exposed to the risk of future changes in market interest rates. The Group is also exposed to interest rate risk through its borrowings related to the purchases of plant and equipment under secured asset financing arrangements with floating rates of interest over their term. At 30 June 2023, the value of secured asset finance borrowings with a floating rate of interest is $115.2 million. Holding all other variables constant, the impact on post tax profit of a 1 percent increase/ decrease in the rate of interest on these secured asset finance borrowings of the Group is $1.15 million. Borrowings related to the purchases of plant and equipment under secured asset financing arrangements which have fixed interest rates over their term are not subject to interest rate risk as defined in AASB 7 Financial Instruments: Disclosures. The value of secured asset finance borrowings with a fixed rate of interest is $175.2 million. 139 NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 FInancIal RepoRt FInancIal RepoRt Financial risk management (a) Market risk (continued) (iv) Price risk Exposure The Group is exposed to the risk of fluctuations in the prevailing market prices for the gold and silver currently produced from its operating mines. The Group manages a component of this risk through the use of gold forward contracts and options. These contracts are accounted for as sale contracts with revenue recognised once gold has been physically delivered into the contract. The physical gold delivery contracts are considered a contract to sell a non-financial item and therefore do not fall within the scope of AASB 9 Financial Instruments. The Group's contractual sales commitments are disclosed in note 17. The Group is also exposed to equity securities price risk arising from investments held by the Group and classified in the statement of financial position as financial assets at fair value through OCI and investments accounted for using the equity method. All of the Group's equity investments are publicly traded on the Australian Securities Exchange. (b) Credit risk Credit risk refers to the risk that a counter party will default on its contractual obligation resulting in financial loss to the Group. Credit risk arises from cash and cash equivalents and credit exposures to gold sales counterparties and financial counterparties. (i) Risk management The Group has adopted the policy of dealing with creditworthy counterparties as a means of mitigating the risk of financial loss from defaults. Cash is deposited only with institutions approved by the Board, typically with a current minimum credit rating of A (or equivalent) as determined by a reputable credit rating agency e.g. Standard & Poor’s. Permitted instruments by which the Group hedges gold price risk are entered into with financial counterparties with a minimum credit of A (or equivalent). The Group has established limits on aggregate funds on term deposit or invested in money markets to be placed with a single financial counterparty and monitors credit and counterparty risk. The Group sells the majority of its unhedged gold and silver to counterparties with settlement terms of no more than 2 days. The counterparties have investment grade credit ratings and the exposures, as noted, are short dated. The Group does not have any other significant credit risk exposure to a single counterparty or any group of counterparties having similar characteristics. (ii) Credit quality The credit quality of financial assets that are neither past due nor impaired can be assessed by reference to external credit ratings (if available) or to historical information about counterparty default rates. 140 Trade receivables Counterparties with external credit rating AA Counterparties without external credit rating * Other Total trade receivables Cash at bank and short-term bank deposits AA A * Other - counterparties with no defaults in the past 30 June 2023 $M 30 June 2022 $M 114.1 2.3 116.4 1,114.1 19.2 1,133.3 57.2 1.0 58.2 538.5 32.6 571.1 Financial risk management (b) Credit risk (continued) (iii) Impaired trade receivables In determining the recoverability of trade and other receivables, the Group performs a risk analysis considering the type and age of the outstanding receivable and the creditworthiness of the counterparty. If appropriate, an impairment loss will be recognised in profit or loss. The Group does not have any impaired Trade and other receivables as at 30 June 2023 (2022: nil). No allowance for expected credit losses has been recognised as the duration of associated exposures is short and/or the probability of default is immaterial. (c) Liquidity risk The Group manages liquidity risk by monitoring immediate and forecasted cash requirements and ensures adequate cash reserves are maintained to pay debts as and when they fall due. Prudent liquidity risk management implies maintaining sufficient cash and marketable securities and the availability of funding through an adequate amount of committed credit facilities to meet obligations when due. At the end of the reporting period, the Group held a short term on-demand cash balance of $1,133.3 million (2022: $571.1 million) that was available for managing liquidity risk, noting that the Group intends to use the proceeds from the USD$600M bond for general corporate purposes including capital expenditures such as funding the KCGM mill expansion. Management monitors rolling forecasts of the Group's available cash reserves on the basis of expected cash flows. The Group's liquidity management policy seeks a target to maintain available cash (comprising cash on hand, deposits at call, bullion awaiting settlement and available undrawn debt) of approximately three months of total recurring operational and corporate expenditure. (i) Financing arrangements The Group had access to the following undrawn borrowing facilities at the end of the reporting year: Floating rate - Revolving credit facility The credit facilities may be drawn at any time. 30 June 2023 $M 30 June 2022 $M 1,000.0 900.0 141 The revolving credit facilities may be drawn at any time until maturity (June 2024: $500 million, undrawn and June 2025: $500 million, undrawn). Refer to note 8(e) for full details of financing facilities available to the Group. (ii) Maturities of financial liabilities The tables below analyse the Group's financial liabilities into relevant maturity groupings based on their contractual maturities. The amounts disclosed in the table are the contractual undiscounted cash flows. Balances due within 12 months equal their carrying balances as the impact of discounting is not significant.

In particular, there is information about: • • • changes to the structure that occurred during the year as a result of business combinations and the disposal of a discontinued operation interests in joint operations interests in associates. A list of significant subsidiaries is provided in note 15. The weighted average interest rate on secured asset financing was 2.65% (2022: 2.37%). 13 Business combination 12 Capital management (a) Risk management The Group's objectives when managing capital are to: • safeguard their ability to continue as a going concern, so that they can continue to provide returns for shareholders and benefits for other stakeholders, and • maintain an optimal capital structure to reduce the cost of capital and maximise returns to Shareholders and benefits for other stakeholders. In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to Shareholders, return capital to Shareholders, issue new shares or adjust the amount of any share buy back. Total capital is equity, as shown in the statement of financial position. The Group is not subject to any externally imposed capital requirements. (b) Dividends (i) Ordinary shares 142 Final ordinary fully franked dividend for FY22 of 11.5 cents (FY21: 9.5 cents) per fully paid ordinary share paid on 29 September 2022 (FY21: 29 September 2021) Interim ordinary fully franked dividend for FY23 of 11.0 cents (FY22: 10.0 cents) per fully paid ordinary share paid on 29 March 2023 (FY22: 29 March 2022) (ii) Dividends not recognised at the end of the reporting period In addition to the above dividends, since year end the Directors have recommended the payment of an unfranked final dividend of 15.5 cents per fully paid ordinary share (2022 - 11.5 cents) as at 30 June 2023. The aggregate amount of the proposed dividend expected to be paid on 12 October 2023 (2022: 29 September 2022) out of retained earnings at 30 June 2023, but not recognised as a liability at year end, is 30 June 2023 $M 30 June 2022 $M 134.0 126.5 260.5 110.7 116.4 227.1 30 June 2023 $M 30 June 2022 $M 178.5 134.0 (iii) Franking credits At 30 June 2023 the value of franking credits available was $3.9 million (2022: $135.1 million). The Company does not expect to generate franking credits for at least 18 months due to tax synergies arising upon the Merger with Saracen Mineral Holdings Limited temporarily reducing the Company’s taxable income. Accounting policy The acquisition method of accounting is used to account for all business combinations, regardless of whether equity instruments or other assets are acquired. The consideration transferred for the acquisition of a subsidiary comprises the: fair values of the assets transferred; liabilities incurred to the former owners of the acquired business; equity interests issued by the Group; fair value of any asset or liability resulting from a contingent consideration arrangement; and fair value of any pre-existing equity interest in the subsidiary. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are, with limited exceptions, measured initially at their fair values at the acquisition date. The application of acquisition accounting requires significant judgement and estimates to be made, which are discussed below. The Group engages independent third parties to assist with the determination of the fair value of assets acquired, liabilities assumed, non-controlling interest, if any, and goodwill, based on recognised business valuation methodologies. The income valuation method represents the present value of future cash flows over the life of the asset using: • financial forecasts, which rely on management’s estimates of reserve quantities and exploration potential, costs to produce and develop reserves, revenues, and operating expenses; • long-term growth rates; • appropriate discount rates; and • expected future capital requirements. The market valuation method uses prices paid for a similar asset by other purchasers in the market, normalised for any differences between the assets. The cost valuation method is based on the replacement cost of a comparable asset at the time of the acquisition adjusted for depreciation and economic and functional obsolescence of the asset and estimates of residual values. The Group recognises any non-controlling interest in the acquired entity on an acquisition-by-acquisition basis either at fair value or at the non-controlling interest’s proportionate share of the acquired entity’s net identifiable assets. Acquisition-related costs are expensed as incurred. The excess of the consideration transferred and the amount of any non-controlling interest in the acquiree over the acquisition date fair value of the net identifiable assets acquired is recorded as goodwill. If those amounts are less than the fair value of the net identifiable assets of the subsidiary acquired and the measurement of all amounts has been reviewed, the difference is recognised directly in profit or loss as a bargain purchase. If the initial accounting for the business combination is not complete by the end of the reporting period in which the acquisition occurs, an estimate will be recorded. Subsequent to the acquisition date, but not later than one year from the acquisition date, the Group will record any material adjustments to the initial estimate based on new information obtained that would have existed as of the date of the acquisition. There were no business combinations for the year-ended 30 June 2023. 143 NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 FInancIal RepoRt FInancIal RepoRt (a) Prior period - Power Business Acquisition On 23 November 2021, NST announced that it agreed to acquire Newmont Corporations' Kalgoorlie power business from Newmont Corporation's Australian subsidiary, Newmont Australia, for US$95M. As part of NST's purchase of 50 per cent of KCGM Pty Ltd on 3 January 2020, NST paid US$25M for an option to buy Newmont Corporation's Kalgoorlie power business. The 110MW Parkeston Power Station and associated infrastructure primarily provides electricity security to KCGM. Parkeston also supplies electricity to the Kalgoorlie area through its connection to the South-West Interconnected System. The plant has a history of continuous reliable power generation. The transaction was completed on 1 December 2021. The cost of the US$25M option was deducted from the final purchase price, with US$70M paid at completion.

(b) Prior period - Paulsens and Western Tanami 144 As outlined in the Group’s Business Combination accounting policy above, the identification of assets and liabilities and associated fair value measurement as part of acquisition accounting is subject to significant judgement and estimation. The following key estimates and judgements were required as part of the acquisition accounting for the power business: Property, plant and equipment - the valuation of these assets involved use of, amongst other factors, publicly available historical capital unit costs, industry benchmarks, producer price index factors, current replacement/reproduction costs, useful life assumptions, residual values and site inspections to determine current asset conditions and utilisation. Intangible assets - the valuation of these assets involved use of, amongst other factors, grid reliability assumptions and various costs assumptions including of backup power station costs, energy cost, network charges, capex costs, balancing costs, demand charges, transmission costs, instillation costs and discount factors. Deferred tax liability - the recognition of deferred tax liabilities is directly associated with the determination of both initial accounting values and the determination and allocation of tax bases on entry into the Group's tax consolidated group. The balance reflects the non-deductibility for tax purposes of the intangible assets. Revenue and profit contribution The power business does not generate revenue, given its purpose to provide electricity to KCGM. Acquisition related costs Acquisition related costs of nil (2022: $2.8 million) are included in acquisition and integration expense in profit or loss. On 13 April 2022, the Company announced it had entered into a binding agreement to sell the Paulsens Gold Operations and Western Tanami Gold Project to Black Cat Syndicate Limited (“BCS”). 145 The transaction completed on 15 June 2022.

During the year, the Company granted 3,433,460 (2022: 3,878,634) FY23 long term incentive (LTI) rights, 29,349 FY22 LTI rights and 986,521 (2022: 726,225) short term incentive (STI) rights to senior management, including key management personnel. The rights were granted under the FY20 share plan as approved at the Company's annual general meeting on 25 November 2020. During the year, 1,490,460 LTI rights and 349,819 STI rights were forfeited or lapsed. The number of vested and unvested performance rights outstanding as at 30 June 2023 was 8,051,956 rights. 150 Retention Rights A retention right is a conditional right which, upon the satisfaction or waiver of the relevant vesting conditions, and, if required by the Company the exercise of that right, entitles its holder to receive one share. During the year, the Company granted 2,190,000 retention rights to senior management, including key management personnel. During the year, 40,000 retention rights were forfeited. The number of retention rights outstanding as at 30 June 2023 were 2,150,000. NED Share Rights A NED share right is a conditional right to a fully paid ordinary share, where vesting is measured on 30 June in each financial year of issue, based on the length of time the NED was on the Board, with pro-rata reduction where the Director ceases to be a director before the end of the relevant financial year. As disclosed in the FY22 Remuneration Report no FY23 NED rights would be issued and the remuneration of the non-executive directors would be paid in cash. Therefore during FY23 no NED rights were granted and 19,285 were exercised. The number of NED share rights outstanding as at 30 June 2023 were 8,488. Restricted Shares Restricted shares are time-tested shares under holding lock with no performance conditions other than remaining employed by a certain date. No restricted shares were granted during the current year. During the prior year, 35,000 restricted shares (all of which remain on issue at 30 June 2023) were granted under the FY20 Retention Share Plan, subject to a 24 month performance condition and holding lock to 12 July 2023. For each of the above grants, the weighted average assessed fair value at grant date is as follows: Share-based payments (c) Performance Rights, Retention Rights, NED Share Rights and Restricted Shares (continued) LTI Performance Rights STI Performance Rights Retention Performance Rights NED Share Rights Weighted average fair value at grant date FY2023 grant $5.95 $7.87 $7.33 - FY2022 grant $6.80 $9.54 - $9.28 The fair value of LTI performance rights and retention rights at grant date is independently determined using a Monte Carlo simulation model (market based vesting conditions) and a Black Scholes Model (non market vesting conditions) that takes into account the term of the performance rights, the impact of dilution (where material), the share price at grant date and expected volatility of the underlying share, the expected dividend yield, the risk-free rate for the term of the performance right and the correlations and volatilities of the peer group companies.

These policies have been consistently applied to all the years presented, unless otherwise stated. The consolidated financial statements are for the Group consisting of Northern Star Resources Limited and its subsidiaries. Defined terms have the meaning given in the Glossary on page 176 of this Annual Report. (a) Basis of preparation These general purpose consolidated financial statements have been prepared in accordance with Australian Accounting Standards and Interpretations issued by the Australian Accounting Standards Board and the Corporations Act 2001. Northern Star Resources Limited is a for-profit entity for the purpose of preparing the consolidated financial statements. (i) Compliance with IFRS Compliance with Australian Accounting Standards ensures that the financial statements and notes of the Company and the Group complies with international financial reporting standards (IFRS). (ii) Historical cost convention The consolidated financial statements have been prepared on a historical cost basis, except for the following: • financial assets at fair value through other comprehensive income, financial assets and liabilities (including derivative instruments). (iii) New and amended standards adopted by the Group The Group has adopted all of the new, revised or amending Accounting Standards and Interpretations issued by the Australian Accounting Standards Board ('AASB') that are mandatory for the current reporting period. With the exception of AASB 2018-6 Amendments to Australian Accounting Standards - Definition of a Business, any new, revised or amending Accounting Standards or Interpretations that are not yet mandatory have not been early adopted. Refer to note for details of changes to accounting policies in the current financial year. Any significant impact of the accounting policies of the Group from the adoption of these Accounting Standards and Interpretations are disclosed below. 156 (iv) Accounting Standards issued but not yet effective Certain new accounting standards, amendments to accounting standards and interpretations have been published that are not mandatory for 30 June 2023 reporting periods and have not been early adopted by the Group. These standards, amendments or interpretations are not expected to have a material impact on the entity in the current or future reporting periods and on foreseeable future transactions. (v) Climate change considerations Summary of significant accounting policies (a) Basis of preparation (continued) (v) Climate change considerations (continued) The accounting-related measurement and disclosure items that are most impacted by our commitments, and climate change related risk more generally, relate to those areas of the financial statements that are prepared under the historical cost convention and are subject to estimation uncertainties in the medium to long term. Future changes to the Group’s climate change strategy or changes to transition risks, including external global decarbonisation ambitions, may impact some of the Group’s significant judgements and key estimates, and could result in material changes to financial results and the carrying values of certain assets and liabilities in future reporting periods. The Group’s current climate change strategy is reflected in the Group’s significant judgements and key estimates which can be identified in the relevant notes to the financial statements as below: (i) Mine properties, property, plant and equipment, and intangible assets - estimation of the remaining useful economic life of assets for depreciation and amortisation purposes Mine properties, property, plant and equipment, and intangible assets are depreciated/amortised to estimated residual values over the estimated useful lives of the specific assets, or the estimated remaining life of the associated mine, predominantly as units of production over recoverable reserves method, with some assets on a straight-line basis. The estimated useful lives of our assets and operations align with our Net Zero Ambition and therefore indicate no material adjustment is required to our depreciation rates or amortisation rates due to climate change related risks. (ii) Rehabilitation and decommissioning provisions - estimation of the timing of closure and rehabilitation activities A provision for future rehabilitation and decommissioning costs requires estimates and assumptions to be made to varying levels of precision based upon the age of the assets and when the proposed closure will take place. Many of these rehabilitation and decommissioning events are expected to take place at the end of the current life of asset plans and these align with our Net Zero Ambition. In FY23 no material changes to the rehabilitation provisions have been made due to climate change related risks. (iii) Impact of climate change on our business - useful economic lives of our power generating assets Currently, Northern Star’s power is principally supported by fossil fuel-based power generation, which we are progressively displacing in part with renewable-based power. In December 2021, Northern Star completed the acquisition of Newmont’s Kalgoorlie power business, comprising a 50% interest in the 110 MW Parkeston Power Station and associated infrastructure which provides electricity to KCGM and the Southwest Interconnected System (SWIS). The acquisition also allowed the full KCGM load to be sourced via the SWIS, reducing the need to generate on a regular basis. With the future transition to renewable-based power, the remaining useful economic life of Parkeston power station has been considered. Our Operations require a consistent electricity supply. Currently the storage capacity for renewable energy is limited and there is a need for this technology to be enhanced. At 30 June 2023 there was no impairment or accelerated depreciation of these assets but this will be reconsidered at each balance sheet date. 157 In July 2021, Northern Star announced a Net Zero Ambition. In February 2022 in the CY2021 Sustainability Report, we outlined our planned decarbonisation pathways targeting a 35% reduction in our Scope 1 and Scope 2 Emissions by 2030 (from a 1 July 2020 baseline). Since these announcements, we have: I. II. continued to engage with investors on our decarbonisation strategy; continued our work commenced in 2018 in phased alignment with the Task Force on Climate related Financial Disclosures (TCFD); continued work planning and developing Emissions Reduction projects; expanded the measurement of and understanding of our Scope 3 Emissions; embedded climate change related risks in our strategic risk profile; developed a model for financial quantitative assessment of material physical and transition risks, and included in our FY22, FY23 and FY24 remuneration framework rewards for senior management with inclusion of long term incentive performance right KPIs linked to reduction of absolute Scope 1 Emissions and Scope 2 Emissions III.

The amendment requires entities to apply the amendments retrospectively, but only to items of Property, Plant and Equipment made available for use on or after the beginning of the earliest period presented in the financial statements. This amendment prohibits entities from deducting from the cost of an item of property, plant and equipment any sales proceeds earned from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, such sales proceeds must be recognised in profit or loss. The Group’s accounting policy has historically been to capitalise the revenue and costs associated with projects not yet having reached commercial production against the mine properties balance in the consolidated statement of financial position. The Group has adopted the amendment in the year ending 30 June 2023 and updated its accounting policy to address this with the final sentence in the paragraph below, being added to the Mine Development accounting policy. Expenditure incurred in constructing a mine by, or on behalf of, the Group is accumulated separately for each area of interest in which economically recoverable Reserves and Resources have been identified. This expenditure for example includes direct costs of construction, drilling costs and removal of overburden to gain access to the ore, borrowing costs capitalised during construction and appropriate allocation of attributable overheads. Further, any revenue generated during the pre production phase of mining will be recorded in profit and loss as revenue with appropriate costs allocated and charged to profit or loss. The change in accounting policy has resulted in a retrospective reclassification of certain elements of previously capitalised assets to revenue and costs in the Consolidated Statement of Profit or Loss and Comprehensive Income, impacting both the current and prior periods. Prior period revenue and costs of sales in the Consolidated Statement of Profit and Loss to 30 June 2023 has been adjusted by upwards $70.9 million and $39.0 million respectively with a corresponding net increase of $31.9 million to Mine Properties in the Consolidated Statement of Financial Position. The change in policy has been applied retrospectively and comparative information has been restated with the opening balance comparative adjustment at 1 July 2021 for pre production revenue and costs recorded prior to this date was a $14.0 million increase to mine properties, $4.2 million increase in deferred tax liability and $9.8 million impact to retained earnings. This had the following impact on the amounts recognised in the financial statements: Condensed Consolidated Statement of Financial Position (extract) Mine Properties Deferred Tax Liability Net Assets Retained Earnings Total Equity Condensed Consolidated Statement of Financial Position (extract) Mine Properties Deferred Tax Liability Net Assets Retained Earnings Total Equity 30 June 2021 Movement $M 6,684.1 (925.3) 7,978.5 1,528.5 7,978.5 $M 14.0 (4.2) 9.8 9.8 9.8 1 July 2021 Restated $M 6,698.1 (929.5) 7,988.3 1,538.3 7,988.3 30 June 2022 $M 6,319.8 (1,094.2) 8,214.9 1,731.2 8,214.9 Movement FY21 $M 14.0 (4.2) 9.8 9.8 9.8 Movement FY22 $M 31.9 (9.6) 22.3 22.3 22.3 30 June 2022 Restated $M 6,365.7 (1,108.0) 8,247.0 1,763.3 8,247.0 158 Summary of significant accounting policies (b) Australian Accounting Standards Board amendment (continued) Condensed Consolidated Statement of Profit or Loss and Other Comprehensive Income (extract) Revenue Cost of Sales Profit before income tax Income tax expense Profit for the period Condensed Consolidated Statement of Changes in Equity (extract) Balance at 1 July 2021 Prior period adjustment - change in accounting policy Restated total equity at 1 July 2021 Profit for the year (restated) Total comprehensive income for the period Dividends Balance as at 30 June 2022 Balance at 1 July 2022 Prior period adjustment - change in accounting policy Restated total equity at 1 July 2022 Condensed Consolidation Statement of Cashflows (extract) Cashflows from operating activities Receipts from customers (inclusive of GST) Payments to suppliers and employees Net cash inflow from operating activities Cashflow from investing activities Payments for mine properties Net cash outflow from investing activities Year-ended 30 June 2022 Movement $M 3,735.4 (3,221.8) 610.1 (180.3) 429.8 $M 70.9 (39.0) 31.9 (9.6) 22.3 Year-ended 30 June 2022 Restated $M 3,806.3 (3,260.8) 642.0 (189.9) 452.1 Retained Earnings Movement $M 1,528.5 - 1,528.5 429.8 429.8 (227.1) 1,731.2 Retained Earnings $M 1,731.2 - 1,731.2 $M - 9.8 9.8 22.3 22.3 - 32.1 Movement $M - 32.1 32.1 Retained Earnings Restated $M 1,528.5 9.8 1,538.3 452.1 452.1 (227.1) 1,763.3 Retained Earnings Restated $M 1,731.2 32.1 1,763.3 Year-ended 30 June 2022 Movement $M 3,695.0 (2,173.8) 1,599.2 (497.6) (881.3) $M 70.9 (39.0) 31.9 (31.9) (31.9) Year-ended 30 June 2022 Restated $M 3,765.9 (2,212.8) 1,631.1 (529.5) (913.2) Basic and diluted earnings per share for the prior year have also been restated.

The Group controls an entity where the Group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power to direct the activities of the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Group. They are deconsolidated from the date that control ceases. Intercompany transactions, balances and unrealised gains and losses on transactions between Group companies are eliminated. The consolidated financial statements incorporate the assets and liabilities of all subsidiaries of Northern Star Resources Limited ('Company' or 'parent entity') as at 30 June 2023 and the results of all subsidiaries for the year then ended. Northern Star Resources Limited and its subsidiaries together are referred to in this financial report as the Group or the consolidated entity. (ii) Joint arrangements Under AASB 11 Joint Arrangements investments in joint arrangements are classified as either joint operations or joint ventures. The classification depends on the contractual rights and obligations of each investor, rather than the legal structure of the joint arrangement. Northern Star Resources Limited has only joint operations. A joint operation is a joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets, and obligations for the liabilities, relating to the arrangement. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require unanimous consent of the parties sharing control. Joint operations Northern Star Resources Limited Limited recognises its direct right to the assets, liabilities, revenues and expenses of joint operations and its share of any jointly held or incurred assets, liabilities, revenues and expenses. These have been incorporated in the financial statements under the appropriate headings. Details of the joint operation are set out in note 15(b). (iii) Changes in ownership interests 160 The Group treats transactions with non-controlling interests that do not result in a loss of control as transactions with equity owners of the Group. A change in ownership interest results in an adjustment between the carrying amounts of the controlling and non-controlling interests to reflect their relative interests in the subsidiary. Any difference between the amount of the adjustment to non-controlling interests and any consideration paid or received is recognised in a separate reserve within equity attributable to owners of Northern Star Resources Limited. When the Group ceases to consolidate or equity account for an investment because of a loss of control, joint control or significant influence, any retained interest in the entity is remeasured to its fair value with the change in carrying amount recognised in profit or loss. This fair value becomes the initial carrying amount for the purposes of subsequently accounting for the retained interest as an associate, joint venture or financial asset. In addition, any amounts previously recognised in other comprehensive income in respect of that entity are accounted for as if the Group had directly disposed of the related assets or liabilities. This may mean that amounts previously recognised in other comprehensive income are reclassified to profit or loss. (d) Foreign currency translation (i) Functional and presentation currency Items included in the consolidated financial statements of each of the Group's entities are measured using the currency of the primary economic environment in which the entity operates ('the functional currency'). The consolidated financial statements are presented in Australian Dollars which is Northern Star Resources Limited's functional and presentation currency. (e) Investments and other financial assets (i) Classification The Group classifies its financial assets in the following measurement categories: • • those to be measured subsequently at fair value (either through OCI or through profit or loss), and those to be measured at amortised cost. Summary of significant accounting policies (e) Investments and other financial assets (continued) (i) Classification (continued) The classification depends on the entity’s business model for managing the financial assets and the contractual terms of the cash flows. For assets measured at fair value, gains and losses will either be recorded in profit or loss or OCI. For investments in equity instruments that are not held for trading, this will depend on whether the Group has made an irrevocable election at the time of initial recognition to account for the equity investment at fair value through other comprehensive income (FVOCI). The Group reclassifies debt investments when and only when its business model for managing those assets changes. (ii) Measurement At initial recognition, the Group measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss (FVPL), transaction costs that are directly attributable to the acquisition of the financial asset. Transaction costs of financial assets carried at FVPL are expensed in profit or loss. Financial assets with embedded derivatives are considered in their entirety when determining whether their cash flows are solely payment of principal and interest. Debt instruments Subsequent measurement of debt instruments depends on the Group’s business model for managing the asset and the cash flow characteristics of the asset. There are three measurement categories into which the Group classifies its debt instruments: • • • Amortised cost: Assets that are held for collection of contractual cash flows where those cash flows represent solely payments of principal and interest are measured at amortised cost. Interest income from these financial assets is included in finance income using the effective interest rate method. Any gain or loss arising on derecognition is recognised directly in profit or loss and presented in other gains/(losses) together with foreign exchange gains and losses. Impairment losses are presented as separate line item in the consolidated statement of profit or loss. FVOCI: Assets that are held for collection of contractual cash flows and for selling the financial assets, where the assets’ cash flows represent solely payments of principal and interest, are measured at FVOCI. Movements in the carrying amount are taken through OCI, except for the recognition of impairment gains or losses, interest income and foreign exchange gains and losses which are recognised in profit or loss. When the financial asset is derecognised, the cumulative gain or loss previously recognised in OCI is reclassified from equity to profit or loss and recognised in other gains/(losses). Interest income from these financial assets is included in finance income using the effective interest rate method. Foreign exchange gains and losses are presented in other gains/(losses) and impairment expenses are presented as separate line item in the consolidated statement of profit or loss. FVPL: Assets that do not meet the criteria for amortised cost or FVOCI are measured at FVPL. A gain or loss on a debt investment that is subsequently measured at FVPL is recognised in profit or loss and presented net within other gains/(losses) in the year in which it arises. Equity instruments The Group subsequently measures all equity investments at fair value. Where the Group’s management has elected to present fair value gains and losses on equity investments in OCI, there is no subsequent reclassification of fair value gains and losses to profit or loss following the derecognition of the investment. Dividends from such investments continue to be recognised in profit or loss as other income when the Group’s right to receive payments is established. Changes in the fair value of financial assets at FVPL are recognised in other gains/(losses) in the consolidated statement of profit or loss as applicable. Impairment losses (and reversal of impairment losses) on equity investments measured at FVOCI are not reported separately from other changes in fair value. 161 NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023NORTHERN STAR RESOURCES LIMITED ANNUAL REPORT 2023 FInancIal RepoRt FInancIal RepoRt Summary of significant accounting policies (e) Investments and other financial assets (continued) (iii) Hedging Net investment hedges Hedges of a net investment in a foreign operation are accounted for in a similar way as cash flow hedges. Gains or losses on the effective portion of the hedge are recognised directly in equity (in the FCTR) while any gains or losses relating to the ineffective portion are recognised in the profit or loss. On disposal of the foreign operation, the cumulative value of gains or losses recognised in the FCTR are transferred to profit or loss. Hedge Ineffectiveness The Group aims to transact only highly effective hedge relationships, and in most cases the hedging instruments have a 1:1 hedge ratio with the hedged items. However, at times, some hedge ineffectiveness can arise and is recognised in profit or loss in the period in which it occurs. (iv) Impairment From 1 July 2022, the Group assesses on a forward looking basis the expected credit losses associated with its debt instruments carried at amortised cost and FVOCI. The Group applies the simplified approach permitted by AASB 9 Financial Instruments, which requires expected lifetime losses to be recognised from initial recognition of the receivables. (f) Goods and Services Tax (GST) Revenues, expenses and assets are recognised net of the amount of associated GST, unless the GST incurred is not recoverable from the taxation authority. In this case it is recognised as part of the cost of acquisition of the asset or as part of the expense. Receivables and payables are stated inclusive of the amount of GST receivable or payable. The net amount of GST recoverable from, or payable to, the taxation authority is included with other receivables or payables in the Statement of Financial Position. Cash flows are presented on a gross basis. The GST components of cash flows arising from investing or financing activities which are recoverable from, or payable to the taxation authority, are presented as operating cash flows. (g) Rounding of amounts 162 The Company is of a kind referred to ASIC Legislative Instrument 2016/191, relating to the 'rounding off' of amounts in the financial statements. Amounts in the financial statements have been rounded off in accordance with the instrument to the nearest hundred thousand dollars, or in certain cases, the nearest dollar. 25 Parent entity financial information (a) Summary financial information The individual consolidated financial statements for the parent entity, Northern Star Resources Limited, show the following aggregate amounts: Balance sheet Current assets Non-current assets Total assets Current liabilities Non-current liabilities Total liabilities Shareholders' equity Issued capital Reserves Financial assets at fair value through OCI Cash flow hedges Share-based payments Retained earnings Profit for the year Total comprehensive income (b) Guarantees entered into by the parent entity 30 June 2023 $M 1,190.8 7,672.4 8,863.2 (176.7) (1,973.3) (2,150.0) 30 June 2022 $M 632.5 7,459.6 8,092.1 (282.5) (927.8) (1,210.3) 6,317.1 6,435.0 13.1 - 29.7 353.2 194.8 194.8 13.0 (0.3) 15.2 418.9 462.2 462.2 Refer to note 23 for details of guarantees entered into by the parent entity in relation to the debts of its subsidiaries.

(d) Contractual commitments for the acquisition of property, plant or equipment Refer to note 17 for commitments of the Group for the acquisition of property, plant and equipment as at 30 June 2023 or 30 June 2022. (e) Determining the parent entity financial information The financial information for the parent entity, Northern Star Resources Limited, has been prepared on the same basis as the consolidated consolidated financial statements, except as set out below. (i) Investments in subsidiaries, associates and joint venture entities Investments in subsidiaries, associates and joint venture entities are accounted for at cost in the consolidated financial statements of Northern Star Resources Limited. (ii) Tax consolidation legislation Northern Star Resources Limited and its wholly-owned Australian entities have implemented the tax consolidation legislation. The head entity, Northern Star Resources Limited, and the controlled entities in the tax consolidated Group account for their own current and deferred tax amounts. These tax amounts are measured as if each entity in the tax consolidated Group continues to be a stand-alone taxpayer in its own right. In addition to its own current and deferred tax amounts, Northern Star Resources Limited also recognises the current tax liabilities (or assets) and the deferred tax assets arising from unused tax losses and unused tax credits assumed from controlled entities in the tax consolidated Group.

The funding amounts are determined by reference to the amounts recognised in the wholly-owned entities’ consolidated financial statements. The amounts receivable/payable under the tax funding agreement are due upon receipt of the funding advice from the head entity, which is issued as soon as practicable after the end of each financial year. The head entity may also require payment of interim funding amounts to assist with its obligations to pay tax instalments. Assets or liabilities arising under tax funding agreements with the tax consolidated entities are recognised as current amounts receivable from or payable to other entities in the Group. Any difference between the amounts assumed and amounts receivable or payable under the tax funding agreement are recognised as a contribution to (or distribution from) wholly-owned tax consolidated entities. 164 165 ABN: 43 092 832 892 Registered Office: Level 4, 500 Hay Street, Subiaco 6008, Western Australia PO Box 2008, Subiaco 6904, Western Australia Tel: +61 8 6188 2100 Fax: +61 8 6188 2111 Email: info@nsrltd.com Web: www.nsrltd.com DIRECTORS’ DECLARATION In the Directors' opinion: (a) There are reasonable grounds to believe that the Company will be able to pay its debts as and when they become due and payable; (b) The financial statements and notes for the year ended 30 June 2023 set out on pages 102 to 164 (FY23 Financial Report) comply with the Corporations Act 2001 (Cth), the Corporations Regulations 2001, Australian Accounting Standards and international financial reporting standards, and other mandatory professional reporting requirements; (c) The FY23 Financial Report gives a true and fair view of the consolidated entity's financial position as at 30 June 2023 and of its performance for the year ended on that date; and (d) At the date of this declaration, there are reasonable grounds to believe that the members of the extended closed group identified in note 23 will be able to meet any obligations or liabilities to which they are, or may become, subject by the virtue of the deed of cross guarantee described in note 23.

In our opinion, the accompanying financial report of the Group is in accordance with the Corporations Act 2001, including: • • Giving a true and fair view of the Group’s financial position as at 30 June 2023 and of its financial performance for the year then ended; and Complying with Australian Accounting Standards and the Corporations Regulations 2001. Basis for Opinion We conducted our audit in accordance with Australian Auditing Standards. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Financial Report section of our report. We are independent of the Group in accordance with the auditor independence requirements of the Corporations Act 2001 and the ethical requirements of the Accounting Professional & Ethical Standards Board’s APES 110 Code of Ethics for Professional Accountants (including Independence Standards) (the Code) that are relevant to our audit of the financial report in Australia. We have also fulfilled our other ethical responsibilities in accordance with the Code. We confirm that the independence declaration required by the Corporations Act 2001, which has been given to the directors of the Company, would be in the same terms if given to the directors as at the time of this auditor’s report. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion. Key Audit Matters Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial report for the current period. These matters were addressed in the context of our audit of the financial report as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

KKeeyy AAuuddiitt MMaatttteerr AAccccoouunnttiinngg ffoorr MMiinnee PPrrooppeerrttiieess As at 30 June 2023, the carrying value of mine properties amounts to $6,323.1 million as disclosed in Note 9(d). Accounting for mine properties requires management to exercise significant judgement in determining the appropriate estimates to be applied in the application of the Company’s accounting policy, including: • the allocation of mining costs between operating and capital expenditure, including deferred stripping; and • determination of the units of production used to amortise mine properties. A key driver of the allocation of costs between operating and capital expenditure is the physical mining data associated with the mining activities. For underground operations this includes consideration of the development of declines, lateral and vertical development, as well as capital non- sustaining costs. Open pit mining requires life of mine strip ratios to be determined and continuously reviewed as production progresses. Costs are capitalised to the extent they relate to expenditures incurred in creating future access to ore rather than current period inventory. Amortisation is applied to each area of interest using the expected contained ounces based on the most recent life of mine information. Amortisation rates are updated when estimated life of mine ounces are revised. HHooww tthhee ssccooppee ooff oouurr aauuddiitt rreessppoonnddeedd ttoo tthhee KKeeyy AAuuddiitt MMaatttteerr For the allocation of mining costs our procedures included, but were not limited to: ▪ ▪ ▪ ▪ of key underground effectiveness of obtaining an understanding of, and testing, the controls operating management has in place in relation to the capitalisation mining expenditure and the production of physical underground mining data; assessing the appropriateness of the allocation of costs between operating and capital expenditure based on the nature of the underlying activity, assessing the operating effectiveness of relevant internal controls over cost allocations, and recalculating the underlying physical data; assessing the deferred stripping model by agreeing monthly strip ratios to underlying physical data and performing a comparison to life of area strip ratios based on most recent life of mine information; and checking the mathematical accuracy of the modelling. the allocation based on For the Group’s unit of production amortisation calculations our procedures included, but were not limited to: ▪ ▪ ▪ obtaining an understanding of, and assessing the design of implementation of the key controls management has in place in relation to the calculation of the unit of production amortisation rate; testing the mathematical accuracy of the rates applied; and agreeing the inputs to source documentation, including: total contained ounces to the - the ounces mined during the year to production schedules; - the applicable reserves statement; and - the anticipated development expenditure to life of mine models. These were assessed for reasonableness compared to historical development expenditure for the respective operations.

Judgement is required in the determination of the rehabilitation provision, including: ▪ ▪ ▪ assumptions relating to the manner in which rehabilitation will be undertaken; scope and quantum of costs, and timing of the rehabilitation activities; and the determination of appropriate inflation and discount rates to be adopted. 168 Other Information ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ cost estimates obtaining an understanding of, and assessing the design and implementation of the key controls management has in place to estimate the rehabilitation provision; to rehabilitation agreeing underlying support, including where applicable reports from external experts; challenging the completeness of provisions considering activities undertaken during the year; holding discussions with external experts to understand and challenge the reasonableness of key assumptions and estimates used in the underlying cost estimates; assessing the independence, competence and objectivity of experts used by management; confirming the closure and related rehabilitation dates are consistent with the latest estimates of life of mines; comparing the inflation and discount rates to available market information; and testing the mathematical accuracy of the rehabilitation provision model. We also assessed the adequacy of the disclosures included in Note 9(g) to the financial statements. The directors are responsible for the other information. The other information comprises the information included in the Group’s annual report for the year ended 30 June 2023,, but does not include the financial report and our auditor’s report thereon. Our opinion on the financial report does not cover the other information and we do not express any form of assurance conclusion thereon. In connection with our audit of the financial report, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial report or our knowledge obtained in the audit, or otherwise appears to be materially misstated. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard. Responsibilities of the Directors for the Financial Report The directors of the Company are responsible for the preparation of the financial report that gives a true and fair view in accordance with Australian Accounting Standards and the Corporations Act 2001 and for such internal control as the directors determine is necessary to enable the preparation of the financial report that gives a true and fair view and is free from material misstatement, whether due to fraud or error. In preparing the financial report, the directors are responsible for assessing the ability of the Group to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Group or to cease operations, or has no realistic alternative but to do so. Our objectives are to obtain reasonable assurance about whether the financial report as a whole is free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the Australian Auditing Standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of this financial report. As part of an audit in accordance with the Australian Auditing Standards, we exercise professional judgement and maintain professional scepticism throughout the audit. We also: • Identify and assess the risks of material misstatement of the financial report, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. • Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group’s internal control. Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors. • • Conclude on the appropriateness of the directors’ use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the financial report or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Group to cease to continue as a going concern. Evaluate the overall presentation, structure and content of the financial report, including the disclosures, and whether the financial report represents the underlying transactions and events in a manner that achieves fair presentation. • • Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the financial report. We are responsible for the direction, supervision and performance of the Group’s audit. We remain solely responsible for our audit opinion. We communicate with the directors regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit. We also provide the directors with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, actions taken to eliminate threats or safeguards applied. From the matters communicated with the directors, we determine those matters that were of most significance in the audit of the financial report of the current period and are therefore the key audit matters.
