District Commences Fieldwork at the Tomtebo Property

September 2, 2020 – District Metals Corp. (TSX-V: DMX) (FRA: DFPP); ("District" or the “Company”) is pleased to report that it has commenced field work on its polymetallic Tomtebo Project in the Bergslagen Mining District of south-central Sweden. Initial work consisting of geological mapping, prospecting and geochemical sampling has started at the former Tomtebo Mine, and regionally across the 5,144 hectare Property.  This work will be further complemented by a review of available historic drill core from the Tomtebo Mine starting in mid-September.  These fieldwork programs will augment the historical compilation work and recently flown SkyTEM survey in preparation for a drilling campaign at Tomtebo planned for early-2021.

Tomtebo Property Highlights

  • Boliden’s Garpenberg Mine is located 25 km to the southeast, and the historic Falun Mine is located 25 km to the northwest. Lundin Mining’s Zinkgruvan Mine is located 175 km to the southwest.
  • Tomtebo contains similar host rocks, structure, alteration, and mineralization styles as the Garpenberg, Falun, and Zinkgruvan Mines.
  • Two historic mines, and numerous mineralized prospects are situated along a 17 km trend on the property.  Mineralization at the historic Tomtebo and Lovas Mines appears to be open in all directions (Figure 1).
  • Historic production at the Tomtebo Mine comprised 120,000 tonnes at 4.4% Cu1.  Historic production at the Lovas Mine comprised 330,000 tonnes at 3.5% Zn, 2.5% Pb, and 30g/t Ag2
  • Development work and mining at the historical Tomtebo and Lovas Mines reached depths of 200 m and 190 m, respectively.  Mining operations at Boliden’s Garpenberg Mine and Lundin Mining’s Zinkgruvan Mine are currently at depths of 1400 m and 1300 m, respectively, with resources that remain open at 1600 m.
  • Previously reported historic drill results at the former Tomtebo Mine include:
    • Hole TOMT65001 intersected 4.67 m at 1,087.0 g/t AgEq3 or 28.0% ZnEq4 at the Oscarsgruvan zone (see July 6th, 2020 news release).
    • Hole TOMT70004 intersected 16.17 m at 535.7 g/t AgEq3 or 13.8% ZnEq4 at the Steffenburgs zone (see July 27th, 2020 news release).
    • Hole TOMT16008b intersected 3.6 m at 3.98% Cu, 4.0 m at 11.79% Cu, and 3.4 m at 2.38% Cu at the Gårdsgruvans zone (see August 11th, 2020 news release).
  • Modern systematic exploration has never been previously conducted on the Tomtebo Property.

Garrett Ainsworth, CEO of District, commented: “Compilation of historical drill results at the Tomtebo Mine is complete, and Leapfrog 3D modeling of the mineralized zones continues, which will be greatly enhanced by the additional data obtained from the recently commenced fieldwork.  As an authority in the Bergslagen Mining District, the presence of Dr. Rodney Allen at Tomtebo is significant given his key role in the discovery of polymetallic mineral resources at the world class Garpenberg Mine.  The final SkyTEM data will be available very soon, and thereafter interpretations on the magnetic and conductive data will be developed as an additional layer to define our priority drill targets at the Tomtebo Mine and regionally across the Tomtebo Property.”      

Fieldwork Program

Fieldwork comprising geological mapping, prospecting, and geochemical sampling at the historic Tomtebo Mine will be conducted by Dr. Rodney Allen and Hein Raat.  Dr. Allen was Manager, Geology Research and Development for the Boliden Group in Sweden for ten years. Prior to that position, he studied several polymetallic ore deposits in Sweden. His geological interpretations were instrumental in the discovery of new ore bodies at Garpenberg and Renström.  Mr. Raat was a Geologist for the Boliden Group in Sweden for eight years with the last four years being focused on polymetallic projects in the Bergslagen Mining District.

The review of historical drill results at the Tomtebo Mine prior to initiating fieldwork has provided valuable background information that will assist with the geological interpretation of trends, patterns, and zonation related to polymetallic mineralization.  Mapping at the historic mine will focus on identifying controls of mineralization through detailed mapping of the geology, alteration, and structure in the open pits and where outcrop is present.  Identification of strongly altered limestone to tremolite skarn will be a priority given the importance of this unit to other large polymetallic deposits in the Bergslagen Mining District.  The structural data obtained will improve the 3D modeling of the mineralized zones at depth where frequent structural measurements were historically recorded from the -200 m exploration drift.    

Regional fieldwork at Tomtebo will be conducted by Nicolai Metzger who is an economic geologist with a focus on precious and base metal exploration in Scandinavia.  The regional work will focus on known polymetallic mineral occurrences, preliminary SkyTEM conductive and magnetic anomalies, and outcrop exposures.  Special attention will be given to mapping out characteristic mafic volcanics and marble horizons that are often spatially related to polymetallic mineralization at the Garpenberg, Zinkgruvan, historic Falun, and historic Sala Mines.
