District Intersects 11.0 m at 5.8% Zn, 1.1% Pb, 20 g/t Ag on the Stollberg Property

In This Article:

Vancouver, British Columbia--(Newsfile Corp. - March 26, 2025) - District Metals Corp. (TSXV: DMX) (Nasdaq First North: DMXSE SDB) (OTCQB: DMXCF) (FSE: DFPP); ("District" or the "Company") is pleased to report on drill assay results for five drill holes (GRAGR-151 to -155) completed during the Fall 2024 drill program at the base metal polymetallic Stollberg Property located in the Bergslagen Mining District in south-central Sweden.

A total of 2,438 m was drilled in five holes around the historic Gränsgruvan Mine (operated intermittently from 1943 to 1978) located within the Stollberg Property. This drill program was carried out from mid-October to mid-December 2024 as part of the collaboration with Boliden Mineral AB.

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.

A summary of the Stollberg Property is presented in the news release on October 16, 2024. Compilation work in combination with extensive review and sampling of historic drill core from the historic Gränsgruvan Mine resulted in a better understanding of the geological setting, alteration system and tectonic framework of the area. Whole rock lithogeochemistry from historic drill core samples revealed that the alteration system and style of mineralization are analogous to that at Boliden's operating Garpenberg Mine, which is located approximately 50 km east of the Stollberg Property. As a reference point 3.5 million tonnes with grades of 3.4% Zn, 1.5% Pb, 97 g/t Ag, and 0.33 g/t Au was mined at the Garpenberg Mine in 20241. This tonnage and grades from the Garpenberg Mine is to provide context, but is not necessarily indicative that the Stollberg Property hosts similar tonnages or grades of mineralization.

Highlights:

  • Drill hole GRAGR-152 intersected 28.00 m at 3.68% Zn, 0.70% Pb, 23 g/t Ag, 0.11 g/t Au, and 0.05% Cu (420.0 to 448.0 m)

    • including 11.00 m at 5.80% Zn, 1.1% Pb, 20 g/t Ag, 0.16 g/t Au, and 0.10% Cu (420.0 to 431.0 m)

  • Drill hole GRAGR-154 intersected 9.85 m at 4.52% Zn, 2.44% Pb, 21 g/t Ag, 0.1 g/t Au, and 0.01% Cu (351.3 to 361.15 m)

    • including 4.5 m at 7.81% Zn, 3.57% Pb, 34 g/t Ag, 0.14 g/t Au, and 0.01% Cu (352.1 to 356.6 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) survey2, and all holes showed both in-hole and off-hole EM conductors that likely represent sulphide mineralization.

  • The Stollberg Property contains similar host rocks, structure, alteration, and mineralization styles as the Garpenberg Mineralized Trend, which gives significant support in making a similar new discovery3,4,5.
