"We are happy to announce that we have been able to improve the overall mine plan for Kevitsa. As a result, we not only increase the Mineral Reserves and secure a prolongation of the mine life, we have also been able to optimize the production in a way that pushes the decision point for a possible Stage 5 project up to a couple of years forward. It is, however, important to stress that European policymakers should act more decislivly in order to safeguard the internal nickel value chain from unfair and unsustainable competition," says Stefan Romedahl, President Boliden Mines.

Kevitsa

During 2024 a comprehensive re-estimation of the Mineral Resources has been conducted which has resulted in a new mine plan and updated Mineral Reserves. In total 25 Mtonnes have been added to the Mineral Reserve. During 2024, a total of 9.85 Mtonnes were milled, making the net increase in Mineral Reserves 15 Mtonnes (19%). The increase has resulted in an extended mine life to a total of 10 years, given a pace of production in line with the environmental permit of 10 Mtonnes per year.

In 2023, 20 Mtonnes were downgraded from Mineral Reserves. The same amount has now been converted back, related to the permit application to change the construction method for the Tailing Storage Facility (TSF). This methodological change creates the possibility to increase the TSF to the capacity needed for the current mine plan. The Mineral Resources have increased by 15 Mtonnes (9%) despite the above conversion back to Mineral Reserves. The increase is attributed to the re-estimation conducted in 2024, as well as the incorporation of new assumptions regarding costs, prices and terms.

The total volume as well as average grade for each classification is shown in table 1 below. For 2025, the average production grade will be 0.17 percent for nickel and 0.23 percent for copper, both under the average grade guidance for life of mine plan. The reason for temporarily lower grades is a new and improved mine plan which requires mining in certain low-grade areas of the pit in order to be able to reach better positions in the future.

Additional information about Mineral Resource and Mineral Reserve classification is available at the Boliden web site (Mineral Resources and Mineral Reserves - Boliden) and an updated summary report about Kevitsa Mineral Resources and Mineral Reserves 2024 will be published there shortly. This press release about Kevitsa Mineral Resources and Mineral Reserves has been reviewed and approved by Sofia Höglund, Competent Person and Head of Mineral Resources and Project Evaluation, Boliden, who is a member of The Fennoscandian Association for Metals and Minerals Professionals (FAMMP), an approved organization for competent persons according to PERC.
