District Files NI 43-101 Technical Report for the Viken Deposit

Mineral Resource Estimate in Sweden

Vancouver, B.C. June 13, 2025

June 13, 2025 – District Metals Corp. (TSX-V: DMX) (Nasdaq First North: DMXSE SDB)

(OTCQB: DMXCF) (FRA: DFPP); (“District” or the “Company”) reports that it has filed the

independent NI 43-101 Technical Report for its 100%-owned Viken Energy Metals Property in

Jämtland County, Sweden, related to the updated Mineral Resource Estimate (“MRE”) for the

Property announced on April 29, 2025.

The Technical Report titled “ Updated Mineral Resource Estimate and Technical Report on the

Viken Energy Metals Project, J ämtland County, Sweden ” (the “Technical Report”) was

prepared by P&E Mining Consultants Inc. (“P&E”) in accordance with National Instrument 43-

101 - Standards of Disclosure for Mineral Projects (“NI 43 -101”) and has an effective date of

April 25, 2025.

The Technical Report details the MRE comprising:

Notes:

(1) Mineral Resources which are not M ineral Reserves do not have demonstrated economic viability. The estimate of

Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio -political,

marketing, or other relevant issues.

(2) The Inferred Mineral Resource in this MRE has a lower level of confidence than that applied to an Indicated

Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the

Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.

(3) The Mineral Resource in this MRE was estimated using the Canadian Institute of Mining, Metallurgy and

Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014) and Best Practices

Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM

Council.

(4) The MRE was based on consensus economics forecast US$ metal prices of $72/lb U3O8, $5/lb V2O5, $17/lb Mo,

$8.50/lb Ni, $4.25/lb Cu and $1.30/lb Zn with respective process recoveries of 80%, 80%, 70%, 70%, 50% and

75%,

(5) Overburden, waste and mineralized US$ mining costs per tonne mined were respectively $2.00, $2.50 and $3.00.

(6) Processing and G&A US$ costs per tonne processed were respectively $20 and $2.

(7) Constraining pit shell slopes were 45 degrees.

The Authors of the Technical Report have recognized that the Viken Energy Metals Property

contains Targets for f urther exploration with a potential range of 980 Mt to 1,040 Mt at

grade ranges of 140 to 180 ppm U 3O8, 2,170 to 2,740 ppm V 2O5 and 210 to 260 ppm Mo.

These Targets for further exploration are based on the estimated strike length, depth and width

of the mineralization, as supported by intermittently -spaced drill holes and observations of

mineralized outcrops. The Targets for further exploration are located adjacent to the margins of

the current MRE.

The potential quantities and grades of the t argets for f urther exploration are conceptual in

nature. There has been insufficient work done by a Qualified Person to define these estimates as

Mineral Resources. The Company is not treating these estimates as Mineral Resources, and

readers should not place undue reliance on these estimates. Even with additional work, there is

no certainty that these estimates will be classified as Mineral Resources. In addition, there is no

certainty that these estimates will prove to be economically recoverable.

The Technical Report is available on SEDAR+ ( www.sedarplus.ca) under District’s issuer

profile.

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 shareholder 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

world along with significant M ineral 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 al 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 t echnical report titled “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
