District Provides Drilling Update on the Tomtebo Property
in Sweden
Vancouver, B.C. April 24, 2025
April 24, 2025 – District Metals Corp. (TSX-V: DMX) (Nasdaq First North: DMXSE SDB)
(OTCQB: DMXCF) (FRA: DFPP) ; (“District” or the “ Company”) is pleased to provide an
update from the ongoing core drilling program at the base metal polymetallic Tomtebo Property
located in the Bergslagen Mining District in south-central Sweden.
A total of 1,712.5 m in three drill holes has been completed at the Steffenburgs zone within the
historic Tomtebo Mine area (Figure 1). Drill targeting was designed to systematically test the
broader Steffenburgs zone and its prospective polymetallic mineralized horizon (Rhyolite 1 and
Rhyolite 3-4 contact) with aggressive step outs of 150 m at depth in order to identify high-grade
sea floor massive sulphide lenses in several directions (news release on February 10, 2025).
The drill rig has now moved to Kvistaberget, which is an exploration target located 5 km northeast
of the historic Tomtebo Mine. A total of 700 to 1,000 m of drilling in two to three holes is planned
at Kvistaberget to test a geophysical SkyTEM conductive anomaly associated with historic
mineral occurrences where grab rock sampling returned strong grades of copper and zinc (Figure
2). Based on whole rock geochemistry results, the Kvistaberget target area is located along strike
from the volcanic massive sulphide (VMS) horizon (Rhyolite 1 and Rhyolite 3-4 contact) at the
historic Tomtebo Mine. Kvistaberget has never been previously drill tested.
Highlights:
• Drill hole TOM22-038 (extended from 391.9 to 659.4 m): intersected 18.9 m of
disseminated to stringer style pyrite-pyrrhotite-chalcopyrite mineralization from
498.7 to 517.6 m, which correlates well with a large borehole electromagnetic (BHEM)
off-hole anomaly detected around 503.0 m.
• Drill hole TOM25-044: intersected multiple zones of strongly altered and sulphide
mineralized footwall rocks including:
o 26.0 m of disseminated to stringer style pyrite-pyrrhotite with minor
chalcopyrite mineralization from 42.0 to 68.0 m, which is interpreted as
footwall mineralization, similar to the Gårdsgruvan zone.
o 46.0 m of disseminated to stringer style pyrite-pyrrhotite-sphalerite-galena
and minor chalcopyrite mineralization from 559.0 to 605.0 m with up to 10%
observed sulphides from 561.0 to 577.0 m. A broad off-hole BHEM anomaly
was detected around 567.0 m.
• Drill hole TOM25-045: intersected multiple zones of strongly altered and mineralized
footwall rocks including:
o 7.85 m of disseminated sphalerite-galena-pyrrhotite-pyrite with abundant
gahnite mineralization (680.4 to 688.3 m) which is currently interpreted as the
prospective ‘mineralized horizon’. Two BHEM anomalies were detected around
585 m (off-hole) and 657-684 m (in-hole).
The Steffenburgs zone, historic Tomtebo Mine drill hole plan is shown in Figure 1, and includes
the modelled BHEM plates. Figure 2 shows the proposed drill targets at the Kvistaberget area.
Garrett Ainsworth, CEO of District, commented: “ Deeper drilling at the Steffenburgs zone has
revealed that polymetallic sulphide mineralization continues at depth, and importantly, significant
in-hole and off -hole borehole electromagnetic (BHEM) conductive anomalies have been
identified. We look forward to receiving the drill assay results from Steffenburgs zone in late Q2
2025.
We are very excited to have the drill rig move to the Kvistaberget target area, which has never
been previously drilled. Very positive coincident data at Kvistaberget includes the whole rock
lithogeochemistry, a conductive SkyTEM anomaly, grab rock samples with up to 2% copper and
8.7% zinc (news release on October 28, 2020), and numerous mineral occurrences that have never
been followed up on.”
Under the terms of a definitive agreement dated October 27, 2023, Boliden and District will
collaborate in the development of District’s wholly -owned polymetallic Tomtebo Property and
Boliden’s wholly-owned polymetallic Stollberg Property. Initially, Boli den will be granted the
right to earn (the “Earn -In Option”) up an eighty- five percent (85%) interest in the Tomtebo
Property. Following exercise of the Earn-In Option, the Tomtebo Property will be contributed to
a joint venture, along with Boliden’s Stoll berg Property, under which District will control an
initial fifteen percent (15%) interest. A summary of the terms of definitive agreement as between
Boliden and District is presented in the news release on October 30, 2023.

Tracking the prospective VMS horizon (Rhyolite 1 and Rhyolite 3-4 contact) associated with the
Steffenburgs zone along strike and at depth requires systematic drilling to provide vectors towards
polymetallic sulphide mineralization. The whole rock lithogeochemistry sampling will map out
the stratigraphic succession and alteration intensity, which will refine further drill targeting. This,
together with newly obtained structural data from drill core will significantly improve the
geological understanding and structural framework of the historic Tomtebo Mine area.
Evaluation, compilation and interpretation of all obtained data will identify areas which warrants
follow-up work.
A total of 232 samples for multi-element assay and 111 samples for whole rock lithogeochemistry
were selected. Drill core samples from these three holes were recently sent to Palsatech in Sala,
Sweden for core cutting. The samples will be sent to ALS Geochemistry in Piteå, Sweden for
assay preparation and then to ALS Geochemistry in Loughrea, Ireland for analysis. Assay results
are expected in late Q2 2025.
The Kvistaberget target area is located 5 km northeast of the historic Tomtebo Mine.
Reconnaissance field mapping and sampling indicated a transition of hanging wall and footwall
rocks, similar to the stratigraphic succession detected in the historic Tomtebo Mine area. The
transition zone, which is interpreted as the prospective VMS mineralized horizon (Rhyolite 1 and
Rhyolite 3- 4 contact) , coincides with a SkyTEM conductive anomaly and several grab rock
samples with sulphide mineralization in the near vicinity (Figure 2) . This combination of
geological, geophysical and geochemical indicators highlights the Kvistaberget area as a priority
target.
When drilling at Kvistaberget has been completed then there will be a pause before drilling
resumes at the historic Lövås Mine in Q3 2025.

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 will be prepared for analysis at ALS Geochemistry
in Piteå, Sweden (“PREP-31Y”). Sample pulps will be sent to ALS Geochemistry in Ireland (an
accredited mineral analysis laboratory) for analysis. Samples will be analyzed using a multi -
element ultra trace method combining a four -acid digestion with ICP -MS analytical package
(“ME-MS61”). Over limit sample values will be 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 package (“ME -OG62”). Gold, platinum, and palladium will be
analyzed using the 30 g lead fire assay with ICP-AES finish analytical package (“PGM-ICP23”).
Certified standards, blanks, and duplicates were inserted into the sample shipment to ensure
integrity of the assay process.
