The completion of the basic engineering provides the technical foundation for the next phase of project execution. In parallel, the Company has placed orders for the main process equipment, with manufacturing already underway at international suppliers to the mining industry. The placed orders represent an investment of several million euros, covered by financing already available for the project.

This progress builds on the project’s established regulatory foundation. San Juan has a 30-year extension to its mining licence, valid until 2055, providing long-term regulatory stability.

“The completion of the basic engineering and the start of manufacturing of the main equipment mark a decisive step for San Juan. We are no longer talking only about planning: we are moving towards project execution. We have selected internationally recognised manufacturers and are now moving forward with the key components of the future plant. The objective is clear: to move towards tungsten production in Europe and contribute to strengthening the security of supply of a strategic raw material for our industry,” says Roberto García Martínez, CEO of Eurobattery Minerals.

The main equipment for the crushing section has been awarded to an international manufacturer of technologies for the mining industry. The equipment for the grinding plant has been ordered from a manufacturer specialising in large-scale equipment for mining and heavy industry, which will manufacture the equipment at its facilities in Galicia.

The Company has also advanced the procurement of equipment for the gravity concentration circuit. The shaking tables and concentration spirals have been ordered from two international manufacturers specialising in this type of equipment. This is conventional gravity concentration technology, consistent with the results of metallurgical testwork conducted on San Juan ore.

In addition, Tungsten San Juan has completed the technical and commercial negotiations for the remaining equipment that will form part of the processing plant, including screens, hydrocyclones, thickeners, tanks, pumps, pump boxes and other auxiliary equipment. Final awards for these supplies will be made shortly, taking into account criteria including performance, operational reliability and safety.

“Receiving the final basic engineering report and starting the manufacturing of the main equipment are important steps for the project. At this stage, we are moving from engineering into execution, ensuring that the different equipment packages and plant systems are properly defined and coordinated. Our objective is to move forward in a structured way, with a continued focus on quality, safety and the efficiency of the future operation,” says Pedro Jiménez de Francisco, Project Director of Tungsten San Juan S.L.

Tungsten is a strategic raw material for Europe, with applications in sectors including defence, aerospace, energy, advanced manufacturing and other industrial technologies. Europe is highly dependent on imports and supply is highly concentrated: according to Eurostat, in 2025 China accounted for 68% of the value of European imports of ferrotungsten, followed by Vietnam with 21% and Kazakhstan with 8%*. Together, these three countries accounted for 97% of external supplies of this material to the EU, highlighting the importance of developing European sources of supply.

Forward-looking statements
This press release contains forward-looking statements. Such statements are based on the Company’s current expectations and assumptions and are subject to risks, uncertainties and other factors that could cause actual results or developments to differ materially from those expressed or implied by the forward-looking statements.

The programme, carried out between April and July 2026 in consultation with Minepro Solutions, aimed to determine the concentrate grade and tungsten recovery achievable through conventional gravity concentration.

The tests conducted by SLR Consulting were performed exclusively using a gravity-based circuit. No flotation, no chemical separation reagents and with conventional off-the-shelf equipment.

Main results

The tested circuit, comprising hydrocyclone desliming, spiral concentration, a scavenging stage and a cleaning stage, recovered 49.9% of the tungsten contained in the feed into a concentrate mass equivalent to 0.7% of the original feed. All equipment used is conventional and commercially available: hydrocyclone, spirals, shaking tables and thickener.

Pedro E. Jiménez de Francisco, Project Director of Tungsten San Juan S.L., comments:
“The work programme carried out by SLR has enabled us to thoroughly characterise the behaviour of the ore through an extensive programme of metallurgical tests and mineralogical studies specifically designed to support the engineering and project definition phases.

The results obtained by SLR have been highly satisfactory and not only confirm the significant potential of the deposit but also provide a rigorous technical basis for the design of the future processing plant, allowing key process parameters to be validated and the planned configuration for the different stages of ore treatment to be optimised. This information represents an essential step in reducing technical risks and defining an efficient and competitive processing strategy.”

Market benchmark*
For comparison purposes, the metallurgical parameters published by operating tungsten mines and by projects with an available feasibility or prefeasibility study are presented below. All assets with publicly available data are included, without selection.

Grades expressed in WO3. The last column is the product of grade and recovery, i.e. the tungsten recovered per tonne of ore treated. The figures for operating mines are taken from quarterly reports; those for projects are taken from published feasibility and prefeasibility studies.

Roberto García Martínez, CEO of Eurobattery Minerals AB, comments:
“These results confirm what we have stated about the San Juan project: it is a deposit that can be concentrated by gravity, using standard equipment and without separation chemistry. This means a plant that is simpler to build, less expensive to operate and has a significantly lower environmental footprint than a project requiring flotation.

It is the best possible starting point for detailed engineering and the next phase of the project.”

Next steps
The next steps for the project will be to advance the detailed engineering, plant construction and commissioning in 2027.

“A thorough permitting process is an essential part of developing a mining project in Europe. With this submission complete, we remain focused on advancing Hautalampi towards a permit decision and a future supply of nickel, cobalt and copper from Finland. Responsible mining requires transparency, technical discipline and a willingness to address questions in detail,” said Roberto García Martínez, CEO of Eurobattery Minerals.

The supplementary submission follows a request from the Finnish Supervisory Agency (Lupa- ja valvontavirasto, “LVV”). The request forms part of the ongoing review of the environmental and water management permit application and covers a broad range of technical, environmental and regulatory matters.

FinnCobalt has worked together with its technical consultants and experts to prepare the requested clarifications and update the relevant documentation. The submission provides additional information and updates concerning, among other areas, the management of water and water quality, extractive waste and other waste streams, legacy mining areas and aftercare obligations, and closure planning.

Particular attention has been given to clarifying the relationship between the historic Keretti mining operations and the planned Hautalampi project, including the remaining aftercare measures relating to the former mining area and Outolampi.

“Supplementary information requests are a normal part of the environmental permitting process in Finland, particularly for projects of this nature. We have now provided the requested comments, supplementary information and clarifications, and the Hautalampi permit application is moving forward as expected. Our focus has always been to provide the authorities with clear and complete information throughout the whole process,” said Ilari Kinnunen, Managing Director of FinnCobalt.

The Hautalampi project is being developed in the historic Outokumpu mining region in eastern Finland as a future European source of nickel, cobalt and copper. The project is intended to contribute to Europe’s security of supply of critical raw materials and to the sustainability transition through responsibly mined minerals produced within the European regulatory framework.

Eurobattery Minerals and FinnCobalt will continue to cooperate with the Finnish Supervisory Agency during the ongoing review of the Environmental Permit Application. The Company will inform the market about material developments in the permitting process.

“The second quarter of 2026 has been about disciplined execution. We have strengthened our financial position, increased our ownership in the San Juan tungsten project and reinforced our organisation with highly experienced mining professionals. These are not isolated milestones—they are deliberate steps that strengthen the project and bring San Juan closer to production. Europe has made securing domestic raw materials a strategic priority. Our responsibility now is to deliver,” comments Roberto García Martínez, CEO of Eurobattery Minerals.

As part of these appointments, Agne Ahlenius concludes his executive role after helping establish Tungsten San Juan during its initial phase and supporting the transition to Pedro Jiménez de Francisco as Project Director over the past few months. Eurobattery Minerals thanks Agne for his valuable contribution during this first phase of the project and wishes him every success in the future.

The capital increase has been approved by the General Meeting of Shareholders of Tungsten San Juan S.L. and has been formally registered today on the 23^rd of June 2026. The transaction has been effected through a debt-to-equity conversion, under which Eurobattery Minerals capitalized EUR 700,000 of shareholder loans previously granted to TSJ. Following the transaction, Eurobattery Minerals’ ownership in Tungsten San Juan increased from 51% to 58.58%.

The transaction further underlines the Company’s commitment to the San Juan tungsten project, located in A Gudiña (Ourense, Galicia), and to its target of commencing production in the first quarter of 2027. The increased ownership marks another milestone in the development of the project and further strengthens Eurobattery Minerals’ position as the majority shareholder of TSJ.

“Increasing our ownership to 58.58% demonstrates our continued strong commitment to the San Juan project,” said Roberto García Martínez, CEO of Eurobattery Minerals. “Work is progressing according to plan. Metallurgical testwork continues to advance, and engineering and planning activities for the future processing plant are also moving forward as scheduled. Each of these steps brings us closer to our goal of commencing production of responsibly produced European tungsten in the first quarter of 2027. At a time when Europe is seeking to strengthen its strategic autonomy and secure access to critical raw materials, San Juan represents an opportunity to contribute to a more resilient and competitive European supply chain.”

The San Juan project holds all permits required for mining activities and forms part of Eurobattery Minerals’ strategy to provide responsibly mined minerals from Europe, for Europe.

The Annual Report describes a year of significant progress for Eurobattery Minerals. During 2025, the Company continued advancing the Hautalampi battery mineral project in Finland while taking a major strategic step through the acquisition of a majority stake in the San Juan tungsten project in Spain.

Subsequent to the reporting period, Eurobattery Minerals further strengthened its position through the submission of applications for Strategic Project status under the EU Critical Raw Materials Act (CRMA) for both Hautalampi and San Juan, the publication of the first Sustainability Report for Hautalampi, the initiation of final engineering work at San Juan, and the securing of a financing facility of up to SEK 60 million, sufficient to meet the Company’s working capital requirements and financing needs for at least the next 24 months.

“2025 was a year in which we transformed Eurobattery Minerals from a company focused primarily on exploration into a company with a clear pathway towards production. With San Juan, Hautalampi and a strengthened financial position, we have established a strong platform for the next phase of development. Our focus now is on execution, project advancement and creating long-term value through responsibly mined minerals from Europe, for Europe,” says Roberto García Martínez, CEO of Eurobattery Minerals AB.
