District Provides Drilling Update on the Tomtebo Property in Sweden

Rhea-AI Summary

District Metals Corp. (DMXCF) has provided an update on its drilling program at the Tomtebo Property in Sweden's Bergslagen Mining District. The company has completed 1,712.5m of drilling across three holes at the Steffenburgs zone, with drilling now moved to the previously untested Kvistaberget target located 5km northeast of the historic Tomtebo Mine.

Key findings include:

• Drill hole TOM22-038 intersected 18.9m of mineralization from 498.7 to 517.6m
• TOM25-044 revealed multiple zones including 26.0m and 46.0m of mineralization
• TOM25-045 showed 7.85m of mineralization with multiple BHEM anomalies

The company plans 700-1,000m of additional drilling at Kvistaberget to test a geophysical SkyTEM conductive anomaly. Under a recent agreement with Boliden, District Metals can earn up to 85% interest in the Tomtebo Property. Assay results are expected in late Q2 2025.

Positive

• Multiple mineralized zones discovered in all three drill holes
• Significant BHEM anomalies detected, indicating potential for additional mineralization
• New untested Kvistaberget target shows promising copper and zinc grades from grab samples
• Strategic partnership with Boliden secured for property development

Negative

• Actual mineral grades pending assay results
• Drilling program requires pause before resuming at Lövås Mine in Q3 2025

Vancouver, British Columbia--(Newsfile Corp. - April 24, 2025) - District Metals Corp. (TSXV: DMX) (Nasdaq First North: DMXSE SDB) (OTCQB: DMXCF) (FSE: 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:

• 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.

• 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:

  • 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, Boliden 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 Stollberg 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.
