District Completes Airborne MobileMT Survey at the Viken

Property and Commences MobileMT at the Alum Shale Properties

in Sweden

Vancouver, B.C. June 24, 2025

June 24, 2025 – District Metals Corp. (TSX-V: DMX) (Nasdaq First North: DMXSE SDB)

(OTCQB: DMXCF) (FRA: DFPP); (“District” or the “Company”) is pleased to announce the

completion of a helicopter-borne Mobile MagnetoTellurics System ("MobileMT") survey at the

Viken Property, and now the MobileMT system has been moved to the Alum Shale Properties

(Figure 1) located in the Jämtland and Västerbottens Counties, north-central Sweden.

The MobileMT survey initially commenced at the Viken Property in on June 3, 2025. Preliminary

interpretations indicate that the MobileMT survey has successfully mapped out the mineralized

Alum Shale host rock of the Viken Energy Metals Deposit, which has validated this geophysical

survey for further use at the Company’s Alum Shale Properties. The final results and

interpretations of the MobileMT survey on the Viken Property will likely be released in Q3 2025.

The MobileMT survey at the Alum Shale Properties will comprise approximately 2,700 line

kilometers at 200 meter line spacing, and will aim to identify potential mineralized Alum Shale

for follow up confirmation by drilling. The optimal target for further follow up work will comprise

the shallowest and thickest parts of mineralized Alum Shale. The MobileMT survey has

successfully mapped out the mineralized Alum Shale in detail at the Viken Energy Metals

Deposit, and this geophysical signature will be utilized for identifying drill targets at the Alum

Shale Properties.

Garrett Ainsworth, CEO of District, commented: “Our preliminary confirmation that MobileMT

has effectively mapped out the mineralized Alum Shale at the Viken Energy Metals Deposit is a

technological breakthrough for exploration of mineralized Alum Shale in Sweden. The initial

interpretations of the MobileMT results at the Viken Deposit clearly show the depth to and

thickness of the Alum Shale that corroborates with geological data from historical drill holes. In

an Alum Shale deposit mining scenario, a shallow and thick deposit is important to optimize the

strip ratio and deliver the best economic metrics. We will use this recently identified geophysical

signature to prioritize drill targets outside of the 2025 Viken Deposit mineral resource estimate

and on the Alum Shale Properties.”

About District Metals Corp.

District Metals Corp. is led by industry professionals with a track record of success in the mining

industry. The Company’s mandate is to seek out, explore, and develop prospective mineral

properties through a disciplined science -based approach to create s hareholder value and benefit

other stakeholders.

District is a polymetallic exploration and development company focused on the Viken and

Tomtebo Properties in Sweden. The Viken Property covers 100% of the Viken Energy Metals

Deposit, which contains the largest undeveloped mineral resource estimate of uranium in the

world1 along with significant mineral resource estimates of vanadium, molybdenum, nickel,

copper, zinc, and other important and critical raw materials.

The advanced exploration stage Tomtebo Property is located in the Bergslagen Mining District

of south- central Sweden and is situated between the historic Falun Mine and Boliden’s

Garpenberg Mine that are located 25 km to the northwest and southeast, respectively. Two historic

polymetallic mines and numerous polymetallic showings are located on the Tomtebo Property

along an approximate 17 km trend that exhibits similar geology, structure, alteration and

VMS/SedEx style mineralization as other significant mines within the district.

For further information on the Tomtebo Property, please see the technical report entitled “NI 43-

101 Update Technical Report on the Tomtebo Project, Bergslagen Region of Sweden” dated

effective October 15, 2020 and amended and restated on February 26, 2021, which is available
