District Metals Reports Additional Historic High Grade Polymetallic Drill Intercepts at Former Tomtebo Mine

District Metals Corp has provided an update on the historical drill data compilation work, and the Leapfrog 3D geological model of the historic Tomtebo Mine located within District's polymetallic Tomtebo Property in the Bergslagen Mining District of south-central Sweden. In partnership with EMX Royalty Corp, this work represents an important development for the Tomtebo Property that has never been previously conducted, and has already identified exceptional drill ready targets. Historic drill highlights from the Steffenburgs zone at the Tomtebo Mine show substantial intervals of polymetallic mineralization from 200 to 317 m below surface that remains open along strike and at depth. The historic drill results from the Tomtebo Mine are from campaigns carried out by state-owned Stora AB during 1916 to 1972.

The Steffenburgs zone covers the northwest quadrant of the Tomtebo Mine, and is dominated by silver-zinc-lead mineralization with lesser copper-gold mineralization. The holes highlighted below show mineralization as disseminated, stringer, semi-massive and massive sulphides that remains open along strike and at depth.

Hole TOMT70004 was drilled horizontally from the -200 m exploration drift level and intersected 16.17 m at 535.7 g/t AgEq1 or 13.8% ZnEq2 (2.00 to 18.17 m).

Hole TOMT70003 was drilled horizontally from the -200 m level and intersected 9.81 m at 441.3 g/t AgEq1 or 11.4% ZnEq2 (5.79 to 15.60 m).

Hole TOMT70011 was drilled horizontally from the -200 m level and intersected 1.55 m at 1,458.4 g/t AgEq1 or 37.6% ZnEq2 (26.95 to 28.50 m).

Hole TOMT71036 was drilled downwards at -66° from the -200 m level and intersected 9.5 m at 303.4 g/t AgEq1 or 7.8% ZnEq2 (118.5 to 128.0 m).

Hole TOMT71031 was drilled downwards at -63° from the -200 m level and intersected 17.75 m at 286.5 g/t AgEq1 or 7.4% ZnEq2 (108.8 to 126.55 m).

Hole TOMT71041 was drilled downwards at -75° from the -200 m level and intersected 29.44 m at 260.2 g/t AgEq1 or 6.7% ZnEq2 (5.32 to 34.76 m), 3.34 m at 349.4 g/t AgEq1 or 9.0% ZnEq2 (54.0 to 57.34 m), and 0.68 m at 500.0 g/t AgEq1 or 12.9% ZnEq2 (66.83 to 67.51 m).

The historic polymetallic drill results are reported in AgEq and ZnEq due to the high silver and zinc values that are also common throughout the Bergslagen Mining District. In 2019, reported revenue from Boliden's nearby Garpenberg Mine was accounted by silver at 30%, zinc at 40%, lead at 20%, and gold-copper at 10%3.

Garrett Ainsworth, CEO of District, commented: "The size and scale potential at the former Tomtebo Mine is evident with these additional historic drill results that show wide intervals of strong polymetallic mineralization enriched with precious metals that is open in all directions. The first ever deep penetrating airborne electromagnetic and magnetic survey (SkyTEM312 HP) was recently flown on the Tomtebo Property, and we eagerly await for the final data by late-August, which will be subsequently interpreted by Condor Consulting and Geovista AB."
