District Reports on Viken Deposit Economic Impact Study that Delivers US$7.66 Billion (74.33 Billion SEK) Economic Contribution

District Metals Corp. (TSXV: DMX) (Nasdaq First North: DMXSE SDB) (OTCQX: DMXCF) (FSE: DFPP) ; ("District" or the "Company") is pleased to announce the results of an independent Economic Impact Study ("EIS") completed by BDO Canada LLP for the Viken Energy Metals Deposit (the "Viken Deposit") within the Viken Property located in Jämtland County, Sweden. The EIS evaluates the broader economic and social benefits based upon the proposed Phase 1 mine operation at the Viken Deposit outlined in the Company's Preliminary Economic Assessment ("PEA"). The EIS demonstrates that development of the Viken Deposit would generate substantial economic value for Sweden through project activity, government tax revenues, and long-term employment opportunities.

Viken Deposit EIS Highlights over Conceptual 13-year Phase 1 Mine Operation:

Cumulative total economic contribution of US$7.66 billion (74.33 billion SEK), of which US$7.63 billion (73.99 billion SEK) accrues to Sweden.Direct corporate income taxes totalling US$1.58 billion (15.33 billion SEK).Direct and indirect employment income taxes of US$199.6 million (1,936.4 million SEK) from approximately 1,065 direct and indirect full-time jobs supported during operations.Capital investment and operating spend contributing US$1.48 billion (14.38 billion SEK) in the local and Swedish economy.Additional State Mineral Fee that provides US$21.9 million (212.5 million SEK) for landowners and US$7.3 million (70.8 million SEK) for the Swedish State.

Garrett Ainsworth, CEO of District, commented: "Our recently completed Viken PEA clearly demonstrated the potential financial metrics of the Viken Deposit. The Viken EIS follows up on the Viken PEA results and now highlights an equally important potential outcome - that the benefits extend well beyond the project itself. The Viken Project has the potential to contribute meaningfully to Sweden's economy, generate substantial Local and State tax revenues, and create high-quality jobs for more than a decade based on the proposed first phase of mining at the Viken Deposit. As Sweden moves to strengthen domestic supplies of uranium and other important raw materials needed for energy security, agricultural security and industrial competitiveness, projects must be evaluated not only on their technical and financial merits, but also on the lasting value they can create for society. We believe the Viken Deposit represents an opportunity to deliver significant economic and social benefits while operating to the highest environmental, health and safety standards."

Economic Impact Study

The Viken EIS was completed by BDO Canada LLP using an expenditure based economic modelling approach to estimate the direct and indirect economic impacts associated with construction and operation of the Phase 1 development scenario presented in the Viken Deposit PEA, which has an effective date of June 26, 2026 and is available under the Company's SEDAR+ profile at www.sedarplus.ca. The analysis includes estimated economic contributions, government tax revenues, and employment impacts over the Phase 1 mine operation. Over the projected 13 year first phase of mine operations, the Viken Deposit is expected to generate economic activity through direct mine construction and operations, procurement from Swedish suppliers, employee spending, and downstream economic multipliers. The key findings from the Viken EIS are shown in Tables 1 and 2:
