Gruvaktiebolaget Viscaria Interim Report July–September 2026 2 Q1 Q2 Q3 Q4 The third quarter of 2026 was characterised by continued high levels of activity and several important advances in the work to restart the Viscaria mine. During the period, we continued to strengthen the project’s industrial execution, develop the organisation and advance a number of areas that are critical to achieving our planned production start in 2028. After the end of the quarter, the European Commission designated the Viscaria mine as a Strategic Project under the Critical Raw Materials Act (CRMA). The decision is an important recognition of the project’s significance for Europe’s future copper supply and for the European value chain for critical raw materials. At a time when electrification, the energy transition and security of supply are high on the European agenda, it is encouraging to see Viscaria recognised as one of the projects considered particularly important for the EU’s long-term competitiveness and resilience. In October, we also inaugurated the new rail yard at Leväjärvi. Together with the connection to the Iron Ore Line, which was completed during Q2, this represents a major milestone for the project. The rail yard will form a central part of our future logistics chain and enable efficient transportation of both equipment and copper concentrate. To me, it also serves as a symbol of how the project is steadily progressing from planning into execution. At the same time, we continue to reduce execution risk through strategic partnerships with leading industry suppliers. During the period, we signed a strategic supply and service agreement with Sandvik covering the future underground production fleet and a long-term cooperation agreement with Metso for process equipment to the processing plant. Together, these agreements secure important parts of our future mining and processing operations while increasing predictability as we move towards production. The organisation also continues to evolve in line with the project’s increasing scale and maturity. During the autumn, Andreas Ridderström assumed the role of Chief of Strategy, Procurement & Project Control, while changes were also made to the management structure to further strengthen the company’s execution capabilities ahead of the upcoming construction and ramp-up activities. We have also expanded our collaboration with academia through several new research projects, improving our understanding of the Viscaria mineral system and supporting future exploration efforts. The project financing process is also continuing to develop positively. As recently communicated, the final phase of the financing process is underway with a number of international banks and export credit agencies. The revised completion timeline reflects the complexity of a financing process of this scale and does not affect the overall project timeline. We continue to experience strong support from all parties involved and remain focused on completing the project financing around year-end. Market fundamentals for copper remain attractive. Electrification, the energy transition, digitalisation and investments in energy infrastructure continue to drive long-term demand growth, while the importance of securing European raw material supply is becoming increasingly evident. Against this backdrop, we believe Viscaria’s strategic importance continues to strengthen. In summary, we leave the quarter with a project that continues to develop according to plan. The recognition from the European Commission, the completion of critical logistics infrastructure, important supplier agreements and the continued progress of the project financing process all demonstrate how Viscaria is steadily advancing towards its goal of becoming a modern and responsible copper producer in Kiruna and an important contributor to Europe’s future raw materials supply.

Gruvaktiebolaget Viscaria Interim Report July–September 2026 3 Q1 Q2 Q3 Q4 Development of operations during the period Market – A copper market in deficit The copper concentrate market remained in deficit during the third quarter of 2026. Ongoing production disruptions following the severe winter and heavy rainfall in Chile, combined with the slow recovery of mines affected by production losses in the second half of 2025, continued to constrain supply. The threat of strike action at several Chilean mines towards the end of the quarter further tightened market conditions. The market is expected to remain tight for the foreseeable future. Spot treatment charges (TCs) and refining charges (RCs) for copper concentrate remained negative. Copper prices on the London Metal Exchange (LME) continued to strengthen during the third quarter, supported by stable demand and limited supply. Exploration and geology Viscaria – Further high-grade exploration results and advances in geological understanding Near-mine exploration during Q3 2026 delivered further encouraging results, particularly from the D Zone, while drilling in the B Zone continued to assess extensions to the known mineralisation. The next Mineral Resource Estimate remains scheduled for publication alongside the Q4 2026 Interim Report in February 2027 and will incorporate near-mine exploration drilling completed since the previous update in May 2025. In the D Zone, another significant step-out drill hole, VDD26007, confirmed high-grade copper mineralisation characterised by chalcopyrite, bornite, covellite and chalcocite, together with hematite alteration. Assay results returned 6 metres at 1.9% Cu and 30% Fe from the main D Zone horizon, as well as 4.7 metres at 2.4% Cu and 5.9 metres at 1.3% Cu in the hanging wall sediments. The intersection lies approximately 700 metres down- dip from the current Mineral Resource boundary and follows up on drill hole VDD25013E, which previously returned 10.2 metres at 2.2% Cu. Together, these results highlight the broader scale of the mineralised system and a substantial potential for future resource expansion. The mineralogical trends observed also provide encouraging indications that may help guide exploration towards higher-grade parts of the system. Establishing the extent, geometry and continuity of this mineralisation remains a priority for ongoing exploration. In the B Zone, several new drill holes have provided further evidence of mineralisation extending beyond the current resource model. Assay results were received for drill holes VDD25013 and VDD26005, returning 10.8 metres at 1.02% Cu and 2.99 ppm Ag and 5.8 metres at 1.09% Cu and 5.32 ppm Ag, respectively. These intersections provide crucial links between previous drill holes, strengthening confidence in the overall geological interpretation and assessment of grade continuity. Assay results remain pending for several additional drill holes, which are expected to be available and included in the upcoming resource update. A reflection seismic survey was completed during August in collaboration with Uppsala University and BitsimNOW, covering both the Viscaria mine site and part of the surrounding area. The survey was designed to improve understanding of the geological architecture at depth, including the relationships between host rocks, major structures and mineralisation. Data processing is underway, with first results expected around the turn of the year. The findings will support refinement of the geological model and help identify further exploration targets. Several research projects were also initiated during the quarter, strengthening Viscaria’s collaboration with academia. Researchers and students from the University of Michigan, Stockholm University and the University of Gothenburg visited the site and collected samples for a range of analyses. Together, these projects aim to improve the understanding surrounding the formation, evolution and timing of the Viscaria mineral system. This work will strengthen the geological basis for further exploration within the deposit and across the wider district.

Gruvaktiebolaget Viscaria Interim Report July–September 2026 4 Q1 Q2 Q3 Q4 Arvidsjaur – Significant exploration potential remains across the project area The Arvidsjaur project area, comprising the Eva, Svartliden and Granliden deposits, currently hosts Mineral Resources of 34 Mt of copper-, zinc-, gold- and silver-bearing mineralisation, reviewed and approved by a Competent Person in accordance with PERC standards. Exploration drilling and geophysical surveys completed in recent years continue to indicate significant potential for the discovery of additional mineralisation both within the broader project area and at depth below the current Mineral Resources. Such discoveries could contribute to future Mineral Resource growth and support the long-term development potential of the project area. During Q1 2026, an exploration drilling campaign was initiated at Arvidsjaur, primarily targeting infill drilling at Svartliden while also testing an additional exploration target within the project area. Processing, logging and analytical work continued during Q3 2026. The results will be used to refine geological interpretations and support planning of a follow-up drilling programme during the forthcoming winter season. Mine – Continued mine development ahead of production Work on further developing the mine design and mining sequence, as well as optimising production plans, continued during the quarter. Recruitment within mine planning, geology and production progressed to strengthen the operational organisation ahead of upcoming project phases. Several contractors were en- gaged to rehabilitate the underground mine, and an LOI for drift development was entered into. Land adja- cent to the open pits was largely cleared in preparation for open-pit mining. Initially, blasted rock will be used to construct supporting embankments for the dam facilities. The ventilation system for the initial rehabilita- tion phase was completed. A contract for the open-pit mining works was signed, and blasting in the open pit is being carried out weekly according to plan. During the quarter, Viscaria entered into a long-term partnership agreement with Sandvik for the underground production equipment. Work on establishing Viscaria’s own mine rescue service continued, and internal training programmes for employees are underway. Processing – Organisation scaling up and construction of the plant building underway Work on the construction of the processing plant is progressing at a rapid pace. Engineering activities continued and intensified across multiple disciplines, while the project organisation was further strengthened to support the groundworks and construction activities currently underway. In parallel, additional testing and mineralogical studies were carried out to refine and validate the process flowsheet. This is a natural part of project development as ongoing drilling improves the understanding of the ore bodies. Recruitment for the processing plant organisation ahead of the operational phase is continuing according to plan. Current recruitment includes a process manager and a process engineer, as well as operators who, at this stage, are working at the water treatment plant. Infrastructure – Continued solid progress Work on Viscaria’s infrastructure continued according to plan during the quarter. At the dam facilities, repairs continued on the existing tailings storage facility and clarification pond. Work on the new tailings storage facility progressed largely according to plan. Construction of the service spillway between the existing tailings storage facility and the clarification pond has begun and is being coordinated with the dam works. The pump station building at the clarification pond has been completed, with pumps and other equipment scheduled for installation in 2027. In relation to the power supply, Vattenfall Eldistribution’s contractor has made substantial progress on the groundworks and foundations for the 130 kV switchyard. ABB has been contracted to supply Viscaria’s 20 kV switchgear, including the second transformer, and the associated groundworks are also progressing according to plan. The first 80 MVA transformer is scheduled for installation during the fourth quarter. Discussions have been initiated with three potential electricity suppliers, and various portfolio options will be assessed during the fourth quarter.

Gruvaktiebolaget Viscaria Interim Report July–September 2026 5 Q1 Q2 Q3 Q4 Viscaria Village was inaugurated on 21 September in the presence of around 150 employees, contractors, partners and guests. Developed in partnership with Strawberry Living, MG Link and A&D Arkitekter, the temporary contractor accommodation provides a safe and practical living environment for those involved in constructing the mine and concentrator plant. The facility includes private rooms, communal areas and service facilities, as well as opportunities for exercise and recreation. The first residents moved in on 24 August. Within Site Services, a construction logistics system has been introduced to streamline the handling and administration of all site deliveries. Equipment rental company Renta has established an on-site presence, while Würth has installed an unmanned container stocked with consumables. Water treatment – Ramp-up and handover under way Work to complete the water treatment plant and ramp up production progressed at a high pace during the quarter. By mid-June, all subsystems had been installed and the plant was able to begin treating mine water for metals, uranium and sulphate. Treatment results have been in line with expectations and demonstrate good treatment performance. Ramp-up is progressing at full pace, alongside training of operations personnel ahead of the handover from the project organisation to operations. Treated water is discharged to the receiving water body in accordance with applicable permit conditions. The drinking water facility associated at the water treat- ment plant has also been completed and approved by the relevant authorities. Logistics – Connection to the Malmbanan railway During the quarter, BDX Rail completed the laying of all tracks and points and installed the overhead contact line. The railway yard was inaugurated on 14 October at an event attended by around 200 guests and participants. The Swedish Transport Administration’s physical installations – two sets of points on the main line and two catch points – have been completed. The remaining work relates to ERTMS and includes trial operations, documentation and approval by the Swedish Transport Agency. Construction of the loading hall was delayed following objections from the Swedish Transport Administration regarding drainage at the site. The hall will be erected during the fourth quarter and will be available for use over the winter as a storage facility for materials and equipment delivered to the site. Environmental permit and land allocation – Legal force obtained in 2024 and 2025 In order to resume mining operations at Viscaria, a permit under the Environmental Code for mining and water operations (environmental permit) is required. On April 16, 2025, the Supreme Court rejected an appeal regarding Viscaria’s environmental permit, which was originally granted on May 6, 2024, meaning the permit can no longer be appealed and thus gained legal force. In addition, a land allocation (markanvisning) is required, which was granted by the Chief Mining Inspector on June 29, 2023. On December 6, 2024, the land allocation in favour of the mining concessions Viscaria K no. 3, Viscaria K no. 4, and Viscaria K no. 7 in Kiruna municipality gained legal force. The final and legally binding environmental permit and land allocation mean that Viscaria has all the necessary approvals in place to restart the Viscaria mine. Sustainability – A cornerstone of Viscaria’s operations Viscaria is committed to genuine sustainability work. Therefore, it is required that the business is planned and implemented with solutions that provide good conditions for minimising the negative impact on the environment. During the quarter, Viscaria continued to develop the company’s Environmental and Social Management System (ESMS). Several key governance documents and management plans were finalised, including those relating to climate risks and transition planning. Implementation of the ESMS has commenced, with a focus on integrating the plans into operational practices and establishing clear responsibilities, monitoring processes

Gruvaktiebolaget Viscaria Interim Report July–September 2026 6 Q1 Q2 Q3 Q4 and reporting structures ahead of the mine restart. The work is being carried out in line with internationally recognised frameworks and good industry practice, including the IFC Performance Standards and the Equator Principles. During the year, Viscaria further developed its processes for engagement with external stakeholders through the establishment of an external grievance mechanism. The mechanism is intended to ensure that comments, questions, positive feedback and grievances from affected stakeholders can be raised, documented and addressed in a transparent, predictable and fair manner, in accordance with international good practice. Increased focus has been placed on the early identification and mitigation of environmental and social risks, with the objective of minimising adverse impacts and creating the conditions for stable and sustainable operations over time. As part of this work, an overarching sustainability statement has been developed. The statement aims to clearly define objectives, responsibilities and requirements in preparation for the restart of the mine and during future operations. When the Viscaria mine is commissioned, Viscaria will be one of the most climate-efficient copper mines in the world and thus be able to deliver sustainable and responsibly produced copper to the European market. The company has made commitments in the environmental permit process with far-reaching purification processes, which means that all the effluent water will be purified to very low levels of pollutants during the lowering of water from the old mine as well as the new mine area. The waste rock deposits, which normally largely affect the landscape, will be designed and laid out with geomorphological design. This means that the landscape, which is initially significantly affected by mining operations, will be able to return to natural conditions more quickly after the end of mining operations. Viscaria’s sustainability work is based on the requirements set out in the International Finance Corporation’s (IFC) Performance Standards and the Equator Principles. The aim is to identify, prevent and manage environmental and social risks associated with the company’s investments and projects. The work is structured around seven focus areas with associated targets, which are also based on the principles of the International Council on Mining & Metals (ICMM), Svemin’s guidelines, the TSM Protocols (Towards Sustainable Mining), the UN Sustainable Development Goals (Agenda 2030) and the UN Global Compact. In addition, the results of stakeholder dialogues and external environment analyses have been taken into consideration. The focus areas provide guidance for the company’s continued sustainability work in the years ahead. Monitoring and reporting of sustainability targets have continued throughout 2026. The company has identified a number of critical issues to work on, and a timetable has been drawn up for further work. The purpose is to further strengthen and clarify goals and requirements for the business, both before the restart of the mine and when the company is in production.

Gruvaktiebolaget Viscaria Interim Report July–September 2026 11 Q1 Q2 Q3 Q4 Outlook The company is financially well positioned to continue advancing the project. The Board of Directors’ assessment is that Viscaria will be able to use long-term interest-bearing debt of up to 60 per cent for future financing of the mine and processing plant. The company’s budget and base scenario form the basis for liquidity planning. The capital requirement is continuously analysed, and the company maintains close control to ensure that upcoming investments are aligned with available liquidity, thereby securing liquidity for the next 12 months. Based on the financing timeline, the company has developed several alternative scenarios, under which investments and project activities are adjusted to available liquidity in order to maintain a sound liquidity position until the long-term financing is in place. Copper prices have risen in recent years, with a pronounced rise during 2025. The copper price on the London Metal Exchange has increased by just over 60 per cent over the past five years. From a longer-term perspective, there remains a significant demand gap for copper. In addition, Viscaria benefits from the trend towards more locally produced minerals, as well as structurally higher demand from future European customers. Over the medium to long term, demand within the EU for responsibly produced copper is expected to increase further. Significant risks and uncertainties Mineral exploration is a high-risk activity where only a few of the evaluated projects lead to producing mines. The exploration results are continuously evaluated by the company and there is no guarantee that exploration of mineralisation will lead to commercial production in Kiruna, Arvidsjaur or Smedjebacken. There is no guarantee that the company will be able to generate sufficient funds to finance continued operations. Failure by the company to generate funds at the right time may result in postponed investigations, reduced, or terminated operations. A more detailed description of the company’s risks and uncertainties can be found in the Annual Report for 2025. The Board of Directors believes that the progress made since the Viscaria acquisition was made in 2019 and the intensified development of the project in recent times have significantly reduced the risks. This report has been reviewed by the company’s auditors. Kiruna, 5 November, 2026 Jörgen Olsson CEO

Gruvaktiebolaget Viscaria Interim Report July–September 2026 19 Q1 Q2 Q3 Q4 Notes NOTE 1 ACCOUNTING AND VALUATION PRINCIPLES This interim report has been prepared in accordance with IAS 34 Interim Financial Reporting, the Swedish Annual Accounts Act and the Swedish Financial Reporting Board RFR 1 and for the Parent Company, RFR 2. The same accounting principles and calculation methods were used in the 2025 Annual Report. Key estimates and assumptions Estimates and assumptions are evaluated on an ongoing basis and are based on historical experience and other factors, including expectations of future events considered reasonable under current circumstances. In the parent company, no items are recognized as other comprehensive income, and therefore the total comprehensive income corresponds to the profit for the period. For a more detailed description of key estimates and assumptions, see Note 2 in the Group Annual Report 2025. Costs related to open-pit mining and operating costs for water treatment are presented separately as direct costs, as they are directly attributable to the operations. New and amended standards applied by the Group The new and amended standards with application for fiscal years beginning January 1, 2026, have not had any material impact on the Group’s financial statements. A number of new standards and interpretations become effective for financial years beginning after 1 January 2026 and later. Of the new or amended accounting standards that become effective in 2026 and later, IFRS 18 is expected to have an impact on the financial statements. IFRS 18 replaces IAS 1 and introduces new requirements aimed at improving comparability in financial performance reporting between similar entities, while providing more relevant and transparent information. The standard does not affect the recognition or measurement of items in the financial statements, but the impact on presentation and disclosures is expected to be extensive, particularly with regard to the income statement and management-defined performance measures. IFRS 18 will be applied from 1 January 2027. Segment The Board of Directors evaluates the Group’s operations based on the Group as a whole, and therefore identifies one operating segment, i.e. exploration for and evaluation of Mineral Resources. Operations are conducted in Sweden. The Group’s main operations are conducted in the subsidiary Viscaria Kiruna AB. New and amended standards that are not yet applied by the Group A number of new accounting standards and interpretations come into effect for fiscal years beginning after January 1, 2026, and thereafter, and have not been applied in the preparation of this financial report. The Group has issued warrants to the Board of Directors, senior executives, and key employees. Fair value has been paid for the warrants, and the premium is reported as retained earnings. The holder can only receive shares upon redemption. Upon exercise of warrants, the exercise price will be reported against equity. Share-based payments The Group has granted employee share options to senior executives. The employee share options are classified as equity-settled share-based payments and are measured at fair value at the grant date. The fair value is recognised as an employee benefit expense, with a corresponding increase in equity, and is allocated over the vesting period. The cumulative expense recognised is based on the Group’s estimate of the number of employee share options that are ultimately expected to vest. Rounding differences may occur in the financial tables due to the use of standard rounding conventions. For a more detailed description of the accounting and valuation principles applied to the consolidated financial statements and the Parent Company in this interim report, see the Annual Report 2025.

Exploration – The exploratory work of looking for natural resources, such as mineralisation. Exploration permit – The exclusive right to explore the bedrock in the permit area, with the purpose of finding mineral deposits. Feasibility study – A Comprehensive technical and economic study of selected development options for a mineral project, including detailed appraisals and financial analysis. A feasibility study forms the basis for financing decisions. Geomorphological design – The waste rock is deposited in a way that mimics the natural landscape, with the aim of facilitating nature’s recovery and, in the long term, allowing the mining areas to blend into the surrounding landscape. JORC – An Australian standard for reporting Mineral Resources and Mineral Reserves to the stock market and other stakeholders. Magnetite – Shiny, black, highly magnetic mineral with the chemical composition Fe3O4. Mining – The removal of rock or ore from an open pit or underground mine. Mineralisation – Concentration of potentially economically interesting minerals in the bedrock. Mineral Reserve – Mineral Reserves are the portion of measured and/or indicated Mineral Resource that are considered to be economically recoverable. Mineral Reserves are divided into probable or proven resources depending on the level of knowledge. Mineral Resource – Concentration or occurrence of mineral in or on the earth’s crust in such quantities and of such form, quality and quantity that it has reasonable prospects for eventual economic extraction. Mineral Resources have classes of inferred, indicated, and measured depending on the degree of knowledge about the mineralisation.
