District Continues to Intersect Significant Polymetallic Mineralization at the Tomtebo Property
District Metals Corp. ("District" or the "Company") reported assay results on nine drill holes (TOM21-004 to -012) from the maiden drill program at the high grade polymetallic Tomtebo Property located in the Bergslagen Mining District in south-central Sweden. Drill hole TOM21-004 encountered strong zinc-lead-silver dominant mineralization (Garpenberg-style) at the Oscarsgruvan zone, and holes TOM21-005 to -012 encountered variable grades and widths of zinc-lead-silver and copper-gold dominant mineralization (classic VMS-style) at the Steffenburgs zone with the following drill assay highlights: TOM21-004 intersected 6.5 m at 3.8% Zn, 2.2% Pb, 46.7 g/t Ag, 0.4 g/t Au, and 0.2% Cu (198.9 to 205.4 m) including 1.65 m at 10.9% Zn, 5.0% Pb, 93.4 g/t Ag, 0.4 g/t Au and 0.1% Cu (198.9 to 200.55 m). TOM21-008 intersected 5.3 m at 3.4% Zn, 1.2% Pb, 20.8 g/t Ag, 0.2 g/t Au, and 0.1% Cu (218.7 to 224.0 m). TOM21-009 intersected 3.9 m at 3.7% Zn, 1.5% Pb, 20.3 g/t Ag, 0.2 g/t Au, and 0.1% Cu (141.4 to 145.3 m) and 0.35 m at 4.0 g/t Au, 3.7% Cu, 53.2 g/t Ag, 0.1% Zn, and 0.1% Pb (184.65 to 185.0 m). TOM21-012 intersected 26.3 m at 0.6% Cu, 0.2 g/t Au, 0.8% Zn, 0.4% Pb, 24.4 g/t Ag (301.9 to 328.2 m) including 3.8 m at 0.7% Cu, 0.3 g/t Au, 1.7% Zn, 0.9% Pb, 35.7 g/t Ag (308.55 to 312.35 m). Drill Hole Summaries - TOM21-004 (Oscarsgruvan zone): Hole TOM21-004 was drilled at an angled orientation (-65° dip) to the northeast (40° azimuth) with its collar approximately 30 m east of holes TOM21-002 and -003. This hole targeted silver-zinc-lead mineralization along the most eastern part of the historic mine drift at -200 m level. The exploration drift was intersected at 197.0 m as a 1.9 m void, but drilling continued through the other side. The hole intersected moderately to strongly altered felsic volcanic rocks with trace to disseminated pyrite intercalated by several meter-scale limestone skarn units and mafic dykes from 9.45 to 191.7 m. Several intervals of polymetallic mineralization were encountered from 191.7 to 205.4 m within intensely altered felsic volcanic rocks. This polymetallic mineralization was underlain by strongly to intensely altered felsic volcanic rocks intercalated by meter-scale tremolite-limestone skarn units together with banded magnetite from 205.4 to 268.3 m. Between 268.3 and the end of hole depth of 300.0 m the hole encountered pyroxene-skarn (after limestone). TOM21-005 (Steffenburgs zone): Hole TOM21-005 was drilled at an angled orientation (-49° dip) to the east (81° azimuth), and was designed to confirm historic hole TOM-65-001 which returned 4.67 m (113.9 to 118.57m) at 200 g/t Ag, 13.6% Zn, 6.9% Pb, 0.88 g/t Au, and 0.25% Cu. Hole TOM21-005 was dominated by moderately to strongly altered felsic volcanic rocks throughout. Alteration mineralogy varies from qtz>muscovite schistose rocks to more qtz>phlogopite/muscovite> cordierite rocks, locally with disseminated sulphides. Several meter-sized mafic dykes crosscut the felsic volcanic sequence. Small polymetallic stringer/vein style mineralization was encountered between 192.0 to 197.0 m within altered felsic volcanic rock, however, the historic mineralized intercept was not confirmed, and the end of hole depth was reached at 230.0 m. TOM21-006 (Steffenburgs zone): Hole TOM21-006 was drilled from the same set up as drill hole -005, but at an angled orientation (-65° dip) to the southeast (140° azimuth), and was designed to test a 1.5 m interval of high grade polymetallic mineralization in historic hole TOMT70-011, just south of the historic -200m level exploration drift. This hole was again dominated by moderate to strongly altered felsic volcanic rocks. Altered qtz>phlogopite>cordierite rocks with intercalated mafic dykes transition at 64.0 m to more qtz>muscovite/phlogopite schist. A more massive qtz>phlogopite>muscovite rock with local gahnite clusters and trace to disseminated py/po starts at 96.0 m. Both the silica and sulphide content increase from 113.0 m with local cm-size polymetallic stringers. A massive polymetallic sulphide vein was intersected from 155.05 to 155.90 m hosted by a more massive, coherent qtz>phlogopite rock. Dark green, chaotic phlogopite>chlorite rock/schist with cordierite blasts and impregnations of pyrite were observed from 169.0 to 174.0 m, followed by a chlorite-talc zone, which ends at 179.0 m, indicating intense Mg-alteration likely due to a fluid conduit. The remainder of the hole is dominated by altered qtz>muscovite/phlogopite>cordierite rocks to the end of hole depth of 221.0 m.
