District Releases Additional Historic Drill Results at the Former
Tomtebo Mine Including 4.0 m at 11.79% Copper
Vancouver, B.C. August 11, 2020
August 11, 2020 – District Metals Corp. (TSX-V: DMX) (FRA: DFPP); ("District" or the
“Company”) is pleased to provide a further 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. (TSX -V:EMX), this work represents an important
development for the Tomtebo Property that has never been previously conducted, and continues
to identify exceptional drill ready targets.
Historic drill highlights from the Gårdsgruvans zone at the Tomtebo Mine reveal shallow and
high grade copper mineralization from near surface to a depth of 200 m 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 between 1916 to 1972.
Gårdsgruvans Zone Historic Drill Highlights
The Gårdsgruvans zone covers the southwest quadrant of the Tomtebo Mine where open pit and
underground mining to the -90 m level extracted high grade copper. The majority of historic drill
core from this zone was only analyzed for copper, although significant gold and silver values are
often associated with copper mineralization, as observed in holes TOMT70015 and TOMT71010.
The holes highlighted below show mineralization as disseminated, stringer, semi -massive and
massive sulphides that remains open along strike and at depth.
• Hole TOMT16008b was drilled at -67° from surface and intersected 3.6 m at 3.98% Cu
(9.50 to 13.10 m), 4.0 m at 11.79% Cu (51.60 to 55.60 m), and 3.4 m at 2.38% Cu
(68.60 to 72.00 m).
• Hole TOMT16005 was drilled at -60° from surface and intersected 1.9 m at 6.12% Cu
(47.00 to 48.90 m).
• Hole TOMT57002 was drilled at -70° from surface and intersected 8.3 m at 1.69% Cu
(58.80 to 67.10 m), 3.83 m at 2.21% Cu (73.70 to 77.53 m), and 2.4 m at 1.20% Cu
(79.60 to 82.00 m).
• Hole TOMT68003 was drilled at -55° from surface and intersected 9.36 m at 1.38% Cu
(7.21 to 16.57 m).

• Hole TOMT70015 was drilled horizontally from the -200 m level exploration drift, and
intersected 0.66 m at 14.35% CuEq1 (4.72 to 5.38 m).
• Hole TOMT71010 was drilled at -60° from surface and intersected 5.5 m at 3.80 %
CuEq1 (147.43 to 152.93 m).
Historic production at the Tomtebo Mine comprised 120,000 tonnes at 4.4% Cu where seams up
to 20 m wide of semi -massive to massive sulphides (dominantly chalco pyrite) were extracted 2.
Available production records contain limited information on the actual tonnage extracted and do
not contain evidence of any analysis for Au, Ag, Zn, and Pb having been completed.
The highlighted historic drill holes are shown on plan map and long section in Figures 1 and 2,
respectively. Table 1 shows individual assay results for copper, silver, and gold that comprise
the CuEq values, and there is no record of zinc and lead analysis.
Garrett Ainsworth, CEO of District, comm ented: “The presence of high grade copper enriched
with precious metals at the former Tomtebo Mine is very important. This type of mineralization
and associated alteration confirms that intensely strong feeder zones were active, which is an
essential comp onent of a robust polymetallic mineralizing system in the Bergslagen Mining
District. Boliden’s Garpenberg Mine and Lundin Mining’s Zinkgruvan Mine are excellent
examples of robust polymetallic mineralizing systems that exhibit high grade copper feeder zones.
This set of historic drill results highlights the potential to expand and discover additional high
grade copper mineralization at Tomtebo with potential significant gold and silver values.”
Context of Historic Drill Results
The presence of high gra de copper mineralization at the historic Tomtebo Mine is important in
that it confirms that an intensely hot and long lasting feeder zone with metal -rich hydrothermal
fluids was active. High grade copper feeder zones are important features of Boliden’s Garpenberg
Mine and Lundin Mining’s Zinkgruvan Mine located within the Bergslagen Mining District.
Drill holes TOMT16005, TOMT16008b, TOMT57002, and TOMT71010 encountered high grade
copper mineralization 6 m, 45 m, 47 m and 113 m, respectively, down dip from the southernmost
mine workings. Hole TOMT16009 intersected high grade copper mineralization 14 m along
strike to the south of the southernmost mine workings, which remains wide open.
Holes TOMT68003 and TOMT68004 encountered high grade copper minera lization in between
open pit workings, and show good continuity of mineralization within the mine workings. Hole
TOMT71005 encountered high grade copper mineralization 45 m down dip from the
northernmost mine workings.
Drill hole TOMT71018 was drilled u pwards at 44° from the -200 m level exploration drift, and
encountered high grade copper mineralization enriched with gold and silver 107 m down dip from
the northernmost mine workings. Holes TOMT67001, TOMT70015, and TOMT71007 drilled
high grade copper m ineralization 146 m, 120 m, and 146 m, respectively, down dip from the
northernmost mine workings where mineralization is wide open at depth.

These drill results are historical in nature. District has not undertaken any independent
investigation of the s ampling nor has it independently analyzed the results of the historical
exploration work in order to verify the results. District considers these historical drill results
relevant as the Company will use this data as a guide to plan future exploration prog rams. The
Company also considers the data to be reliable for these purposes, however, the Company's future
exploration work will include verification of the data through drilling.
Next Steps at Tomtebo Property
• Historical data from the Tomtebo Mine cont inues to be digitized, compiled and
interpreted, and further results will be released as interpretations are completed.
• A detailed airborne electromagnetic and magnetic survey (SkyTEM) was recently flown
across the Tomtebo Property. The final SkyTEM dat a is expected by late -August, and
then interpretive work will begin. Any conductive or magnetic high anomalies from the
survey will be followed up as promising targets for high grade polymetallic
mineralization.
• Conductive and magnetic high anomalies will be targeted as part of a broader prospecting,
mapping, and sampling program in late-August. Detailed work will focus on the historic
Tomtebo and Lövås Mines, and the numerous mineral occurrences on the Tomtebo
Property.
• Dr. Rodney Allen, BSc, PhD, from Volcanic Resources has been retained to review all
historical data and available drill core along with ongoing exploration data to assist in
prioritizing drill targets. 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.
