District Intersects 30.4 m of Continuous Intense Sulphide Mineralization at the Tomtebo Property
November 1, 2021 – District Metals Corp. (TSX-V: DMX) (FRA: DFPP); ("District" or the “Company”) is pleased to provide a second update on its Phase II drill program currently underway at its high grade polymetallic Tomtebo Property located in the Bergslagen Mining District in south-central Sweden.
District commenced the 5,000 m Phase II program with two drill rigs in operation at the Tomtebo Property on October 7, 2021 (see news release here). To date, a total of 2,021 m has been drilled in six holes (TOM21-023A/B to -028). Drill holes TOM21-026 to -028 are discussed in this news release, and these drill core samples will be sent to ALS Geochemistry shortly with results expected after the first three holes (TOM21-023A/B to -025).
- Wide and high grade polymetallic mineralization encountered: Hole TOM21-028 intersected 30.4 m of continuous intense sulphide mineralization (143.6 to 174.0 m) including 13.55 m of impregnation to semi-massive sulphides (143.6 to 157.15 m), and 16.85 m of massive sulphides (157.15 to 174.0 m) at the Steffenburgs zone (Figure 1).
- Continuity of mineralization: Hole TOM21-028 was drilled 60 m up plunge from TOM21-025 (previously reported here), which returned 11.0 m of continuous massive sulphide mineralization from 211.4 to 222.4 m. The massive sulphides intersected by hole TOM21-001 (8.2 m at 20.94% ZnEq1 from 65.3 to 73.5 m) appears to be a separate and parallel massive sulphide lens (Figure 2).
- Follow up holes: Hole TOM21-027 was drilled approximately 80 m down plunge of the 11.0 m massive sulphide intercept from TOM21-025 and is interpreted to have clipped the northwest outside edge of the massive sulphide lens (Figure 2). Further step out holes are being considered.
Garrett Ainsworth, CEO of District, commented: “We are delighted to report that hole TOM21-028 has cut through the strongest and widest interval of massive sulphide mineralization on the Tomtebo Property to date. Hole TOM21-027 intersected several intervals of stringer-style sulphide mineralization, which is interpreted as the northwest outside edge of the plunging massive sulphide lenses encountered by holes TOM21-001, -025 and -028. Our second drill rig has been testing the Gårdsgruvans zone where hole TOM21-026 has encountered encouraging alteration with narrow copper sulphide mineralization that indicates the mineralized system continues at depth.

Drill Hole Summaries
TOM21-026 (Gårdsgruvans zone):
Hole TOM21-026 was drilled at an angled orientation (-58° dip) to the east-southeast (110° azimuth). It was designed to step out 70 m down dip from multiple stacked copper-gold feeder zones encountered in hole TOM21-017.
After 6.8 m of overburden, the hole intersected weakly to moderately altered (biotite, cordierite, andalusite, muscovite) felsic volcanic rocks to 56.7 m that was underlain by weakly biotite altered felsic volcanic rock with pyrite (1-5%) and pyrrhotite (0-0.1%) as disseminations and stringers to 70.7 m. Moderate to strongly altered (biotite, cordierite, muscovite) felsic volcanic rocks persist from 70.7 to 244.0 m, and are intruded by a mafic dyke from 244.0 to 252.0 m. Moderate to strongly altered felsic volcanic rocks continue from 252.0 to 380.7 m with copper sulphide veinlets at 290 m and a copper sulphide vein from 323.0 to 323.4 m. A moderately to strongly silicified felsic volcanic rock with cross cutting dykes was observed from 380.7 to the end of hole depth at 459.0 m.
TOM21-027 (Steffenburgs zone):
Hole TOM21-027 was drilled at an angled orientation (-62° dip) to the northeast (35° azimuth). It was designed to step out 80 m down plunge of the 11.0 m massive sulphide intercept (211.4 to 222.4 m) from TOM21-025.
After 12.0 m of overburden, the hole intersected moderately altered (muscovite, biotite, cordierite) felsic volcanic rock with trace pyrite to 62.0 m, which was followed by strongly to intensely altered (biotite, cordierite, anthophyllite) felsic rock with polymetallic sulphide stringers/veinlets (63.8 to 64.4 m) becoming less altered from 80.0 m to 128.0 m. A porphyritic mafic dyke known as a marker unit cuts the felsic rocks from 128.0 to 133.0 m. Moderately to intensely altered felsic volcanic rocks persist from 133.0 to 293.0 m where polymetallic sulphides were observed from 192.0 to 204.0 m as stringers, 270.0 to 271.0 as stringers, and 276.5 to 276.6 m as a veinlet. Several mafic dykes with trace stringer pyrite cutting through moderately altered felsic volcanic rocks were observed from 293.0 to the end of hole depth at 312.0 m.
TOM21-028 (Steffenburgs zone):
Hole TOM21-028 was drilled at an angled orientation (-50° dip) to the northeast (52° azimuth). It was designed infill the 118 m gap between TOM21-001 and -025, which both encountered significant intervals of massive sulphide mineralization.
After 20.0 m of overburden, the hole intersected moderately altered felsic volcanic rocks with trace pyrite to 89.0 m. A porphyritic mafic dyke known as a marker unit cuts the felsic rocks from 89.0 to 92.7 m. Moderately to strongly altered felsic rock with increasing pyrite, pyrrhotite and magnetite content was intersected between 92.7 to 143.6 m. Intensely altered felsic rock with increase in polymetallic sulphide content to impregnation, veins/stringers, and semi-massive was encountered from 143.6 to 157.15 m. Massive sulphides (sphalerite, galena, pyrite, pyrrhotite, chalcopyrite) were intersected from 157.15 to 174.0 m. This high grade and very dense mineralized intercept is underlain by moderately altered felsic volcanic rocks with occasional meter-scale mafic dykes from 174.0 m to the end of hole depth at 218.6 m. Hole TOM21-028 represents the strongest and most extensive mineralization intersected at the historic Tomtebo Mine to date.
1 Metal prices used in USD for the ZnEq calculation were based on Ag $15.00/oz, Au $1650/oz, Cu $2.15/lb, Zn $0.85/lb, and Pb $0.75/lb. ZnEq equals = Zn% + (Ag g/t × 0.0257) + (Au g/t x 2.831) + (Cu% × 2.529) + (Pb% × 0.882). The use of ZnEq is to calculate cut-off grades for exploration purposes, and no adjustments were made for metal recovery.
