Sotkamo Silver AB according to its Ore Reserve estimate updated in December 2023, has assessed that the Ore Reserve of its Silver Mine amounts to a total of 1.45 million tons. The update of the Ore Reserve estimate does not change Sotkamo Silver's guidance or its 2023 production forecast. The company believes that the amount of Ore Reserve and currently known Mineral Resources are sufficient for about 7-8 years of mining and they will be increased with infill and exploration drilling planned for 2024 and 2025.

Mineral Resources are upgraded to Ore Reserve with infill drilling. Exploration drilling increases the amount of known Mineral Resources in the area of the current mine. In the next few years, Sotkamo Silver will invest not only in the current mine, but also in the exploration and development of ore-critical areas in its vicinity.

The Ore Reserve represents the portion of the Mineral Resources where production is concentrated in the short term. In this area, detailed infill drilling is carried out to ensure an optimised mine design. Sotkamo Silver is also striving to ensure with infill drilling that the Ore Reserve increases by at least one year's worth of production annually.

The management of Sotkamo Silver also believes that with constant infill drilling, the company will be able to ensure that the Ore Reserve will be continuously available in sufficient quantities to enable three year?s worth of production. Sotkamo Silver's management and the Board of Directors estimate that a significant portion of the current Mineral Resources, which is not yet included in the Ore Reserve, can be included in the Ore Reserve in the future with continuous infill drilling. Mineral Resources represent assets that are fairly well known but have not yet been drilled in detail.

These resources form the basis of the estimated Life of Mine, which currently extends to 2030. Areas located outside the current Mineral Resources offer additional opportunities for the expansion of the Silver Mine. By the end of 2025, Sotkamo Silver's goal is to extend the Life of Mine to 2035.

In addition to Silver Mine development projects, Sotkamo Silver is also both developing and searching for future growth paths in accordance with its strategy. Sotkamo Silver plans research programs for the company's ore exploration areas and is currently modeling and refining its exploration operations for the coming years.
