Vancouver, B.C. July 29, 2025
July 29, 2025 – District Metals Corp. (TSX-V: DMX) (Nasdaq First North: DMXSE SDB)
(OTCQB: DMXCF) (FRA: DFPP); (“District” or the “Company”) is pleased to report on drill
assay results for five drill holes (extension TOM-22-038, TOM-25-044, TOM-25-045, KVI-25-
001 and KVI-25-002) completed during the February to April 2025 drill program at the base metal
polymetallic Tomtebo Property located in the Bergslagen Mining District in south -central
Sweden.
A total of 2,485 m were drilled in five holes at the Steffenburgs zone within the historic Tomtebo
Mine area and at Kvistaberget, which is a prospective target located 5 km northeast of the historic
Tomtebo Mine area within the Tomtebo Property. This drill program was carried out from early
February to late April 2025 as part of the collaboration with Boliden Mineral AB.
The main objective of this drilling phase was to systematically test the broader Steffenburgs zone
and its prospective polymetallic mineralized horizon with aggressive step outs of 150 m at depth
in order to identify high- grade sea floor massive sulphide lenses in several directions. The
Kvistaberget target was identified by a SkyTEM geophysical conductive anomaly associated with
historic sulphide workings where rock sampling returned strong grades of copper and zinc.
Property-wide geological mapping and geochemical sampling provided evidence that the
“Volcanic Massive Sulphide ( VMS) mineralized horizon ” at the historic Tomtebo Mine area
extends into the Kvistaberget target area that has never been previously drill tested. A drilling
update with detailed information was presented in the news release on April 24, 2025.
Highlights:
• Drill hole TOM -25-044 intersected multiple zones of stringer style chalcopyrite
(copper and gold) mineralization including:
o 0.40 m at 4.3% Cu, 34 g/t Ag, 0.66 g/t Au (45.70 to 46.10 m)
o 1.35 m at 1.2% Cu, 8 g/t Ag, 1.21 g/t Au (53.70 to 55.05 m)
o 4.10 m at 1.7% Cu, 11 g/t Ag, 0.76 g/t Au (58.50 to 62.60 m)
o 1.20 m at 0.5% Cu, 8 g/t Ag, 4.48 g/t Au (138.40 to 139.60 m)
• Drill hole TOM-25-044 intersected 13.0 m at 36 g/t Ag, 2.0% Zn and 0.8% Pb, (561.0
to 574.0 m) including:
o 5.0 m at 65 g/t Ag, 3.1% Zn and 1.3% Pb (569.0 to 574.0 m)
• Drill hole TOM -25-045 intersected multiple zones of strongly altered and mineralized
footwall rocks including disseminated sphalerite-galena-pyrrhotite-pyrite (zinc, lead,
silver) with abundant gahnite (zinc) mineralization which is currently interpreted as
the prospective “VMS mineralized horizon” including:
o 7.85 m at 88 g/t Ag, 3.0% Zn and 1.9% Pb (680.40 to 688.25 m)
• Down-hole electromagnetic results show multiple off -hole conductors: all drill holes
were followed up by Boliden’s in -house, state of the art, down- hole, three component
electromagnetic (DHEM) survey 1, and all holes within the broader Steffenburgs zone
showed both in- hole and off -hole EM conductors that likely represent sulphide
mineralization.
Drill hole plan maps are shown in Figures 1 and 2 and drill assay results are shown in Table 1.
Garrett Ainsworth, CEO of District, commented: “ These latest drill results from the Tomtebo
Property, particularly the intersection of 7.85 meters at 88 g/t silver, 3.0% zinc, and 1.9% lead in
hole TOM-25-045, show that extensive polymetallic mineralization at the Steffenburgs zone
continues at depth with aggressive step outs that remain open. These grades and thicknesses of
base metal polymetallic mineralization encountered at the Steffenburgs zone are consistent with
the presence of VMS mineralized systems, which are characteristic of the prolific Bergslagen
Mining District.
Importantly, the integration of down-hole EM surveys has revealed multiple off-hole conductors,
providing us with highly compelling targets for follow -up drilling. These findings validate our
geological model and exploration strategy.
In September 2025, w e aim to commence drilling at the historic Lövås Mine located at the
northeast end of the Tomtebo Property. The Lövås Mine shows substantial base metal
polymetallic mineralization that is wide open below the mine workings at a depth of 190 m, and
the most recent drilling at the Lövås Mine was in the 1950’s.”
All of the holes recently drilled at the Tomtebo Property have been systematically sampled for
whole rock lithogeochemistry. Interpretation of these results should help with the understanding
of the geological setting, alteration signature and guide exploration in defining new targets.
The Kvistaberget drilling did not intersect significant mineralization, except weakly disseminated
chalcopyrite (copper) mineralization in KVI-25-002 with 2.85m at 0.2% Cu between 239.65 m
and 242.50 m. The SkyTEM anomaly tested in KVI-25-001 could not be explained nor could the
BHEM identify any off-hole conductive signature supporting further investigation.
Drilling at the historic Lövås Mine, located in the northeastern part of the Tomtebo Property, will
commence in September 2025 followed by additional drilling at the Stollberg Property in Q4
2025.

Technical Information
All scientific and technical information in this news release has been prepared by, or approved by
Garrett Ainsworth, P .Geo., President and CEO of the Company. Mr. Ainsworth is a qualified
person for the purposes of National Instrument 43- 101 - Standards of Disclosure for Mineral
Projects.
The drill core reported in this news release was logged and prepared at the District Metals AB
core facility in Säter, Sweden before submittal to Palsatech Oy in Sala, Sweden where the NQ -
size drill core is cut and bagged. The samples were prepared for analysis at ALS Geochemistry
in Piteå, Sweden (“PREP -31Y”). Sample pulps were sent to ALS Geochemistry in Ireland (an
accredited mineral analysis laboratory) for analysis. Samples were analyzed using a multi -
element ultra trace method combining a four -acid di gestion with ICP -MS analytical package
(“ME-MS61”). Over limit sample values were re -assayed for: (1) values of copper >1%; (2)
values of zinc >1%; (3) values of lead >1%; and (4) values of silver >100 g/t using the high-grade
material ICP -AES analytical p ackage (“ME -OG62”). Gold, platinum, and palladium were
analyzed using the 30 g lead fire assay with ICP-AES finish analytical package (“PGM-ICP23”).
Samples values zinc >1% for the historic Tomtebo Mine area were re -assayed for zinc using an
aqua regia digestion with analytical package (“ME-OG46”) to determine and test the gahnite vs
sphalerite content. Certified standards, blanks, and duplicates were inserted into the sample
shipment to ensure integrity of the assay process. Selected samples were chosen for duplicate
assay from the coarse reject and pulps of the original sample. No QA/QC issues were noted with
the results reported.
