District Comments on the Swedish Parliament’s Approval of the Proposal on Appropriate Safety and Radiation Protection Requirements for the Extraction and Processing of Nuclear Materials

Vancouver, B.C. June 15, 2026

June 15, 2026 – District Metals Corp. (TSX-V: DMX) (Nasdaq First North: DMXSE SDB) (OTCQX: DMXCF) (FRA: DFPP); (“District” or the “Company”) welcomes today's approval by the Swedish Parliament (Riksdag) of legislation that streamlines the permitting framework for the extraction and processing of nuclear materials, including uranium.

The approved amendments align the permitting process for nuclear materials more closely with the regulatory framework applicable to other mining projects in Sweden. The changes are intended to create a more transparent, efficient, and predictable permitting process while maintaining appropriate safety and radiation protection standards based on the risks associated with the activity.

A key aspect of the legislation is that the extraction and processing of uranium will now be treated in a manner consistent with other metals and minerals within Sweden's overall permitting framework. The amendments remove the requirement for a separate admissibility assessment under the Environmental Code and eliminate the requirement for municipal council consent for uranium extraction and processing projects, commonly referred to as the municipal veto.

The Swedish Government have stated that these regulatory changes are designed to improve permitting efficiency and provide greater certainty for projects of strategic importance to Sweden's energy security and critical minerals supply chain. The legislation is also expected to support Sweden's contribution to increasing European Union self-sufficiency in critical raw materials while advancing the broader energy transition.

Parallel to this, on June 11, 2026, the Swedish Government presented the terms of reference for a new inquiry that will investigate ways to enhance local and municipal influence for Alum Shale deposits[i]. The inquiry also mentions that it will include concerned parties from the private sector in their stakeholder dialogue. It will also provide an analysis of commercial consequences of any proposal made and will also take into account Sweden’s commitments according to the Critical Raw Materials Act (CRMA).

Garrett Ainsworth, CEO of District Metals, commented: “Today's decision by the Swedish Parliament represents another significant milestone in Sweden's ongoing efforts to strengthen its domestic nuclear fuel and critical minerals supply chains. This change to the permitting framework for uranium fits with Sweden’s ongoing nuclear expansion.

District's commitment to earning and maintaining a strong social and local license remains unchanged. We will continue to engage openly and transparently with municipalities, landowners, Sámi, and other stakeholders, ensuring that our projects are advanced responsibly and to appropriate standards of environmental stewardship, communication, and stakeholder collaboration.

By establishing a more predictable permitting framework for uranium extraction and processing, Sweden is aligning these activities with other mining projects while maintaining robust environmental and safety standards. We believe these changes further enhance the strategic importance of the Viken Deposit and our broader Alum Shale Properties as Sweden and the European Union seek secure, long-term sources of uranium and other important and critical raw materials required for energy security and low-carbon economic competitiveness.

We have also taken note of the separate alum shale inquiry that has now been initiated, and we will engage in the inquiry process with the ambition that Swedish regulators can find ways for enhanced local influence without any new veto mechanisms, such as the veto that has been abolished today.”
