District Executes Contract for Airborne MobileMT Survey on

Alum Shale Properties in Sweden

Vancouver, B.C. February 27, 2026

February 27, 2026 – District Metals Corp. (TSX -V: DMX) (Nasdaq First North: DMXSE

SDB) (OTCQ X: DMXCF) (FRA: DFPP) ; (“District” or the “ Company”) is pleased to

announce that it has entered into a contract with Expert Geophysics Surveys Inc. (“EGS”) to

complete a helicopter -borne Mobile MagnetoTellurics System ( “MobileMT”) survey over

additional mineral licenses within the Company’s Alum Shale Properties in north-central Sweden.

The MobileMT survey will comprise approximately 2,253 line kilometers at 400 meter line

spacing and 4,000 m spaced tie lines over recent mineral license applications (see December 17,

2025 news release) that have now all been approved by the Mining Inspectorate, and are part of

the Alum Shale Properties (Figure 1).

The MobileMT survey is planned to commence in late -June or early -July 2026, subject to

permitting, contractor availability, and weather conditions. Data from the survey will be

processed and interpreted following completion and will be integrated with existing geological,

geochemical, and geophysical datasets.

The optimal target for further follow up work will comprise the shallowest and thickest parts of

mineralized Alum Shale. The relatively flat lying Alum Shale contains abundant graphite and

sulphides that make it a super conductor, which has been previously mapped out in detail by the

MobileMT survey.

In 2025, the high resolution MobileMT survey conducted by EGS successfully identified large-

scale conductive anomalies that correlate with the Viken Energy Metals Deposit, as confirmed by

historic drill holes from 2006 to 2012. The MobileMT survey was confirmed to identify and map

out additional mineralized Alum Shale targets within the Viken Property as strong conductors

(see September 24, 2025 news release).

The Viken Deposit contains the largest undeveloped Mineral Resource Estimate of uranium in

the worldi along with significant Mineral Resource Estimates of vanadium, potash, molybdenum,

nickel, copper, zinc, and other important and critical raw materials as reported in District’s news

release from April 29, 2025.

Vice President Project Development Departure

The Company notes that Mr. Jeremy Veszi will conclude his role as Vice President, Project

Development effective February 28, 2026, reflecting a role alignment related to external

consulting commitments with another uranium company. The Company thanks Mr. Veszi for his

contributions during the early-stage evaluation of the Viken Project.

As part of the Company’s broader project execution strategy, District will transition from an

executive leadership model to a team-based advisory approach and will continue to engage Veszi

Professional Consulting Inc. to provide multidisciplinary support across project development

initiatives, as required. District remains focused on advancing the Viken Project through

disciplined technical work programs supported by internal leadership and specialized external

advisors.
