The Company will continue to inform the market in accordance with applicable stock market rules.

The judgment was subsequently reviewed by the Tribunal Supremo (Supreme Court of Spain), which rendered its judgment on 21 January 2026, and is final. The sentence includes two years’ imprisonment, a fine, and joint and several liability for damages of USD 3.46 million.

A subsequent enforcement decision by the Provincial Court of Bizkaia dated 21 April 2026, as confirmed by a final order dated 29 May 2026, suspended the enforcement of the prison sentence for a probationary period of five years. The suspension is subject to conditions, including monthly payments during the suspension period and payment of 60 per cent of the civil liability amount into the court’s account by the end of that period. Failure to comply with the conditions may result in revocation of the suspension and enforcement of the custodial sentence. The remaining findings of the judgment remain in force.

The Company has furthermore received information that the Swedish Economic Crime Authority (Ekobrottsmyndigheten) has served notice of suspected criminal conduct on Roberto García Martínez in respect of three counts of aggravated insider dealing relating to transactions in the Company’s financial instruments.

The Board is investigating the situation and considering appropriate measures. The Company will provide further information in due course.

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.
