Nordic Mining ASA: Update on Nordic Quartz AS: Preparations underway for next development phase at Kvinnherad - Long-term landowner agreement secured, project team established and drilling program to be initiated

Oslo, Norway - April 8, 2026. Nordic Mining ASA ("Nordic Mining" or the "Company") is advancing the Nordic Quartz project at Kvinnherad into its next development phase. Key milestones have now been achieved, including establishment of a dedicated project team and enhancement of the landowner agreement, ensuring long-term stability. The Company is preparing to initiate necessary regulatory processes, engage with potential customers and partners for product validation, and plan a qualified drilling programme to update the mineral resource estimate in accordance with international reporting standards. Together, these developments strengthen the project's foundation and support the Company's plans for further progression.

The Kvinnherad quartz deposit, held through the wholly owned subsidiary Nordic Quartz AS, has long been a promising asset in Nordic Mining's portfolio. Recent pilot testing has demonstrated that the deposit can be processed to exceptionally high-purity levels, reinforcing its potential as a future source of a high-value industrial mineral.

• Developing a greenfield mineral project is never straightforward. The experience we have gained through bringing Engebø from concept to operation gives us a solid foundation for the next steps at Nordic Quartz. We are applying that hard-earned project development expertise as we assemble the team to advance the Kvinnherad deposit further. The pilot results demonstrate that the material can be processed to purity levels achieved only by a very limited number of quartz deposits globally, making it highly attractive for semiconductor manufacturers and other high-value industrial applications, says Finn Ivar Marum, CEO of Nordic Mining.

Nordic Mining is currently initiating dialogue with several potential partners and customers to validate product quality and suitability for industrial applications, such as crucibles, silicon metal and specialized glassware for the semiconductor and solar PV manufacturing value chains. Nordic Mining sees this phase as an important step toward de-risking the project and welcomes interest from parties seeking long-term, high-quality quartz supply or collaboration opportunities in high-value end markets.

Successful pilot tests yielding semiconductor grade materials

In collaboration with Dorfner Anzaplan GmbH, Nordic Mining has carried out metallurgic testing and pilot-scale production to support the upcoming product qualification with potential customers. In total, 800 kilograms of processed sample material has been produced from raw quartz feedstock from the Kvinnherad deposit. The material underwent a full industrial processing route, including magnetic separation, acid treatment, and hot chlorination, to replicate the conditions of a finished product.

The tests generated high-purity quartz (HPQ) with very low impurity levels, demonstrating that the Kvinnherad quartz deposit is among the most suitable quartz resources globally to produce high-end HPQ.

HPQ is a critical raw material used in semiconductors, fiber optics, and solar-grade applications, where high chemical purity and thermal stability are essential. Demand for HPQ continues to rise, driven amongst others by rapid growth in semiconductor manufacturing linked to AI development and data-center expansion. As a key input in chip production, HPQ plays an increasingly strategic role in global technology supply chains.

Enhanced landowner agreement
The Company has also strengthened its landowner agreement at Kvinnherad, enhancing prospects for long-term planning and stability for the operations, and securing land access and use rights throughout the life of mine. Nordic Mining has the flexibility to advance the project in line with its overall project strategy.

Limited cost in 2026

While no material investments have been made to date, the progression and pace of further development will be aligned with the Company's overall funding situation and capital allocation plans. Nordic Mining expects less than NOK 20 million in costs for the project during 2026.

Although the Kvinnherad Quartz project represents a highly attractive opportunity, Nordic Mining's primary focus remains the continued ramp-up of the Engebø Rutile and Garnet operation toward design capacity by year-end 2026. Progress at Engebø is well underway and remains the Company's top operational priority. The Kvinnherad Quartz project will advance in parallel without drawing resources from Engebø, while at the same time offering additional value-creation potential for the Company.

About Nordic Mining

Nordic Mining ASA ("Nordic Mining" or the "Company"), listed on Euronext Oslo Børs, is a resource company focused on critical minerals. The Company is currently in the ramp-up phase at Engebø on the west coast of Norway, the first greenfield mine established in Norway in 40 years, targeting steady-state production by year-end 2026. Through its wholly owned subsidiary Engebø Rutile and Garnet AS ("ERG"), Nordic Mining holds the mining rights and required permits for a significant mineral deposit estimated to support a 39-year life of mine, positioning the Company as one of very few natural rutile producers globally and the only garnet producer in Europe. In addition, the Group holds a landowner agreement for a high-purity quartz deposit in the Kvinnherad Municipality in Norway, where test results confirm world-class quality. Nordic Mining is now progressing the project toward regulatory approval. With significant growth opportunities beyond current operations at Engebø, Nordic Mining's portfolio is of high international standards and provides a solid long-term value basis for its shareholders.
