District Intersects 29.2 m at 7.4% ZnEq or 2.9% CuEq on the Tomtebo Property

Vancouver, British Columbia--(Newsfile Corp. - July 29, 2024) - District Metals Corp. (TSXV: DMX) (OTCQB: DMXCF) (FSE: DFPP) ("District" or the "Company") is pleased to report on assay results for the six drill holes (extension of TOM22-037B, TOM24-039 to -043) from the Spring 2024 drill program at the high grade polymetallic Tomtebo Property located in the Bergslagen Mining District in south-central Sweden.

A total of 2,196 m in six drill holes was completed during this drill program that was carried out from mid-February to mid-April 2024 as part of the collaboration with Boliden Mineral AB. Strong footwall copper-rich polymetallic sulphide mineralization has been encountered at the Steffenburgs zone of the historic Tomtebo Mine (April 29, 2024 news release).

Drill holes TOM24-041 to -043 targeted the Steffenburgs zone massive sulphide lens down-dip beneath holes TOM21-025, -028 and TOM22-038, which were highlighted by down hole intercepts of 14.3 m at 14.2% ZnEq1 (210.0 to 224.3 m), 30.05 m at 10.9% ZnEq1 (148.35 to 178.40 m), and 25.5 m at 8.2% ZnEq1 (249.0 to 274.1 m), respectively. TOM24-042 was drilled 105 m down-plunge from TOM22-038 where mineralization remains wide open at depth.

Highlights:

• TOM24-042 intersected 29.25 m at 7.4% ZnEq1 or 2.9 CuEq2 (299.0 to 328.25 m)
  • including 19.75 m at 10.0% ZnEq1 or 4.0% CuEq2 (306.0 to 325.75 m)
  • including 13.0 m at 11.8% ZnEq1 or 4.7% CuEq2 (309.0 to 322.0 m)
  • including 2.0 m at 16.1% ZnEq1 or 6.4% CuEq2 (309.0 to 311.0 m)

• TOM24-041 intersected 6.8 m at 3.3% ZnEq1 or 1.3% CuEq2 (191.0 to 197.8 m)
  • including 5.0 m at 4.0% ZnEq1 or 1.6% CuEq2 (192.0 to 197.0 m)

• TOM24-043 intersected 3.95 m at 4.5% ZnEq1 (327.15 to 331.10 m)
  • including 1.65 m at 9.0% ZnEq1 (327.15 to 328.80 m)

A drill hole plan and cross sections are shown in Figures 1 to 3, and drill assay results are shown in Table 1. Although holes TOM24-041 and -042 are copper-rich polymetallic intervals, the zinc equivalent grades are used in the cross sections to better illustrate the grade distribution within the Steffenburgs zone. Drill hole summaries are reported here.

Garrett Ainsworth, CEO of District, commented: "The drill assay results from hole TOM24-042 at the Steffenburgs zone exceeded our expectations in terms of the copper and gold values, and have delivered a strong interval of 29.2 m at 2.9% copper equivalent that remains wide open at depth. We consider our first drill program at Tomtebo in collaboration with Boliden to be a great success, and we look forward to further review with our partner before planning the next phase of drilling at Tomtebo.

"We continue to carry out geological mapping, prospecting, and rock sampling for whole rock analysis across the Tomtebo and Stollberg Properties with an objective of identifying regional drill targets that are coincident with existing geophysical (conductive and magnetic) anomalies of interest. Planning for a drill program at the Stollberg Property in Fall 2024 remains on track."

The Tomtebo drill program was designed to test both geological ideas as well as step outs at depth from previously significant intercepts of polymetallic sulphide mineralization at the Steffenburgs zone at the historic Tomtebo Mine.

Hole TOM22-037B was drilled in 2022 at an angled orientation (-50° dip) to the south (180° azimuth) to 357.9 m. It was designed to test a blind magnetic high anomaly along the interpreted Volcanic Massive Sulphide (VMS) mineralized horizon located 900 m northeast along trend from the historic Tomtebo Mine. Interpretation of the lithogeochemical samples taken in 2022 indicated that the hole did not pass the mineralized horizon and warranted continuation. TOM22-037B was extended by 200 m to 557.75 m. Although no significant mineralization was intersected, it can be concluded that the drill hole did pass through the VMS target horizon.

Both TOM24-039 and -040 were significant step outs northwest from the historic Tomtebo Mine to test the interpreted VMS mineralized horizon towards the west. These drill holes all intersected moderate to strong hydrothermally altered felsic volcanic rocks, which indicates that they are still within the Tomtebo VMS mineralized system. However, no significant polymetallic sulphide mineralization was intersected, but whole rock geochemical results should determine the rock precursor and alteration intensity. This should determine if the drill holes passed the VMS target horizon.

Drill hole TOM24-041 to -043 targeted the Steffenburgs zone massive sulphide lens down-dip. All holes intersected intense proximal footwall-style alteration and associated footwall stringer sulphide veins and sulphide impregnation. In addition, TOM24-042 intersected extensive strong semi-massive to massive sulphide mineralization, earlier than expected and was observed to be copper-rich, which could be intense footwall VMS mineralization rather than the sea floor massive sulphide intersected in hole TOM21-001, -025 and -028. The structural complexity of the Steffenburgs zone makes it difficult to delineate the seafloor massive sulphides at the expected VMS mineralized horizon, and warrants systematic drilling in combination with down-hole electromagnetic plate modeling and whole rock geochemical interpretation work.

Notes:

• All intervals are core lengths, and true thicknesses are yet to be determined. Mineral resource modeling is required before true thicknesses can be estimated.
• Cut-off grade of 1.3% ZnEq was utilized, which may include up to 2.0 m of internal dilution. Underground mining cut-off at the nearby Garpenberg Mine was US$46.60/tonne in 2023.
• Metal prices used in USD for the ZnEq cut-off calculations were based on Ag $15.00/oz, Au $1650/oz, Cu $2.15/lb, Zn $0.85/lb, and Pb $0.75/lb.
• ZnEq = Zn% + (Ag g/t × 0.0257) + (Au g/t x 2.831) + (Cu% × 2.529) + (Pb% × 0.882)
• CuEq = Cu% + (Au g/t x 1.1192) + (Ag g/t × 0.0102) + (Zn% x 0.3953) + (Pb% x 0.3488)
• The use of ZnEq and CuEq is to calculate cut-off grades for exploration purposes, and no adjustments were made for metal recovery.

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 package ("ME-OG62"). When required, additional over limit sample values were re-assayed for: (1) values of zinc >30%; (2) values of lead >20% using the high precision analysis of base metal ores AAS analytical package ("Zn, Pb-AAORE"). Gold, platinum, and palladium were 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. 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.
