District Commences Airborne MobileMT Survey
at the Alum Shale Properties in Sweden
Vancouver, B.C. July 6, 2026
July 6, 2026 – District Metals Corp. (TSX -V: DMX) (N asdaq First North : DMXSE SDB)
(OTCQX: DMXCF) (FRA: DFPP); (“District” or the “Company”) is pleased to announce that
Expert Geophysics Surveys Inc. (“EGS”) has been retained to conduct a helicopter-borne Mobile
MagnetoTellurics System ("MobileMT") survey at the Alum Shale Properties (Figure 1) located
in the Jämtland and Västerbottens Counties, north-central Sweden.
The MobileMT survey will comprise approximately 2,253 line kilometers at 400 meter line
spacing over the Alum Shale Properties (Figure 1). In June 2025, t he MobileMT survey
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. Approximately half of the 151,329 hectare Alum Shale Properties were flown with
the MobileMT Survey in July 2025 where numerous large and conductive anomalies were
identified as potential targets for Alum Shale mineralization.
Priority follow up targets are expected to comprise the shallowest and thickest accumulations of
mineralized Alum Shale. The relatively flat lying Alum Shale unit contains abundant graphite,
resulting in a highly conductive signature associated with the Viken Deposit that was successfully
delineated in detail by the June 2025 MobileMT survey. The survey demonstrated the
effectiveness of MobileMT in mapping prospective mineralized Alum Shale horizons and
refining drill targets across District’s Alum Shale and Viken Properties.
Garrett Ainsworth, CEO of District, commented: “The decision to expand the MobileMT survey
across our Alum Shale Properties is supported by the excellent results achieved at the Viken
Deposit, where the survey successfully mapped the mineralized Alum Shale host rock and
validated MobileMT as a highly effective exploration tool. With approximately half of our Alum
Shales land package surveyed to date, we have already identified numerous large conductive
anomalies that we have recently started to drill test at the Österkälen mineral license.
The extensive graphite content within the Alum Shale creates a strong conductive signature that
can be effectively mapped using MobileMT. This next phase of surveying will significantly
advance our understanding of the district -scale potential across our Alum Shale P roperties and
support our objective of discovering additional Viken-style Alum Shale deposits in Sweden.”
EGS introduced its MobileMT system in 2018 for use in Airborne Natural Source Audio
Frequency MagnetoTellurics (“AFMAG”), positioning it as the most advanced generation of
airborne AFMAG technology. This system harnesses energy from global thunderstorm act ivity,
which is converted into an underground electromagnetic plane wave, serving as the primary field
in the airborne natural field. The electromagnetic fields and currents induced in the subsurface
are then utilized by MobileMT to detect variations in subsurface electrical resistivity to map out
geological units of interest.

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 2025 TSX Venture 50 company, ranking among the top-
performing issuers on the TSX Venture Exchange in the past year.
District is a uranium polymetallic exploration company focused on its flagship Viken Property in
Sweden. The Viken Property covers 100% of the Viken Deposit, which 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.
On June 2, 2026, the Company announced the results of a Preliminary Economic Assessment (the
“PEA”) for the Viken Deposit that outlined an after-tax NPV8% of US$2.88 billion, IRR of 45.9%,
and payback period of 2.1 years. The assessment included an initial capital cost of US$876 million
to generate average after-tax free cash flow of US$531 million per year over the 13 years of life
of mine production.
For further information on the Viken Property, please see the technical report entitled “NI 43-101
Updated Mineral Resource Estimate and Technical Report on the Viken Energy Metals Project,
Jämtland County, Sweden” dated effective April 25, 2025, which is available on SEDAR+ at
www.sedarplus.ca and the Company’s news release dated June 2, 2026 for further details on the
PEA.
