District Reports on Initial Geological Work at the Tomtebo
Property
Vancouver, B.C. September 30, 2020
September 30, 2020 – District Metals Corp. (TSX-V: DMX) (FRA: DFPP); ("District" or
the “Company”) is pleased to report on the results of its recently completed initial fieldwork at
its polymetallic Tomtebo Project in the Bergslagen Mining District of south-central Sweden. This
initial work consisted of geological mapping, prospecting and geochemical sampling at the former
Tomtebo Mine, and regionally across the 17 km mineralized trend within the 5,144 hectare
Property (Figure 1). This fieldwork will be further complemented by a recently commenced
review of available historic drill core from the Tomtebo Mine. The fieldwork program and review
of historic drill core will enhance the historical data compilation and recently flown SkyTEM
survey, all in preparation for a drilling campaign at Tomtebo planned for early-2021.
Initial Fieldwork Highlights
• All outcrops in the former Tomtebo Mine area and most outcrops around the mine area
were mapped and sampled, and strongly altered and mineralized rocks were identified
to the south and southwest of the historic Tomtebo Mine for at least 600 m . Surface
mapping west, north and east of the mine was not possible due to a veneer of overburden,
but the recently flown SkyTEM survey is expected to provide valuable information about
this area with no outcrop.
• All rocks within the two accessible Tomtebo open pits are strongly altered throughout
with occurrences of sulphide mineralization. Varying proportions of silicification
(quartz-flooding), phlogopite/biotite, and anthophyllite were observed, which are all
important alte ration minerals associated with polymetallic mineralization in the
Bergslagen District. Also, a t remolite skarn after former limestone was identified, often
one of the controls on mineralization in the District.
• Sulphide mineralization observed at the Tomtebo open pits comprises disseminated
and stockwork vein -style pyrite and chalcopyrite with minor pyrrhotite,
arsenopyrite and sphalerite. The dominance of pyrite-chalcopyrite in a strongly quartz-
phlogopite altered host rock, suggests hot hydrothermal fluids from the core of a
hydrothermal system, which confirms the open pit mine areas as proximal feeder zones.
• Geological work at the Nyberget area which encompasses the historic Lövås Mine
mapped out two large marble units with associated replacement s tyle banded semi -
massive to massive sulphide mineralization . Quartz vein with abundant chalcopyrite

from a historic showing was also identified, which is interpreted as distal to massive
sulphide mineralization or epigenetic mineralization.
• Regional geological work at the Kvistaberget area identified several mineral occurrences
consisting of small pits and underground workings where quartz-chalcopyrite veins were
mined.
Garrett Ainsworth, CEO of District, commented: “Our preliminary geological work at the former
Tomtebo Mine and regionally across the Tomtebo Property has provided us with valuable
information that is being integrated with existing historical data and our recently flown SkyTEM
survey to generate an even more robust understanding of t he geologic package on the Property .
Surface mapping of the open pits at the Tomtebo Mine has provided geological data that correlates
well with the historic drill data, and provides additional confidence in the orientation of structures
and mineralization at the Tomtebo Mine. Also, geological work on several regional areas within
the Property identified and confirmed important indicators that have enhanced the possibility of
discovering additional polymetallic mineralization.”
Fieldwork at Historic Tomtebo Mine
The objective of ongoing geological work at the historic Tomtebo Mine is to identify the rock
types and the hydrothermal alteration pattern that hosts the copper-gold and silver-zinc-lead
mineralization, interpret the structural geom etry of the rock units, and determine relationships
between the mineralization and the stratigraphy and structure. Th e data and subsequent
interpretations, combined with evaluation of the historical drill data, interpretation of the
conductive and magnetic data from the recently flown SkyTEM survey, and ongoing 3D
modeling of the mineralized zones at the Tomtebo Mine will form the basis for defining priority
drill targets.
Mineralization at the Tomtebo Mine is within strongly altered felsic volcanic rocks, which are
most likely stratified felsic volcanic ash sandstone-siltstone. An altered limestone bed (altered to
tremolite skarn) up to one meter thick occurs in the east wall of the southernmost open pit. The
mine workings (and likely mineralization) appe ar to be discordant to both the bedding and the
foliation. Confirmation on the orientation of mineralization will be crucial for drill targeting, and
the presence of tremolite skarn is significant given this unit’s relevance to other large
polymetallic deposits in the Bergslagen Mining District.
Mineralogical layering and early foliation are observed locally throughout the Tomtebo Mine
area, and are defined by bands of varying quartz and phlogopite content and trains of andalusite
porphyroblasts. This l ayering shows a consistent northwest to southeast orientation, and a
moderate dip to the southwest. An overprinting foliation shows a consistent east-west orientation
and sub-vertical dip. The structural data suggests that the Tomtebo Mine area is on the w estern
limb of an antiform that plunges moderately to the west-southwest. This structural data obtained
from surface mapping correlates well with the 3D modeling of the mineralized zones at depth
where frequent structural measurements were historically recorded from the -200 m exploration
drift.
Rock samples have been sent to ALS Geochemistry in Malå, Sweden for multi-element analysis.
Whole rock geochemical samples were recovered to quantify the alteration intensity and assist
with the interpretation of the protolith lithologies.

Regional Fieldwork
The regional fieldwork focused on known polymetallic mineral occurrences, preliminary
SkyTEM conductive and magnetic anomalies, and outcrop exposures. Much of the Tomtebo
Property has a thin veneer of overburden, so mineral occurrences at the historic Lövås Mine
within the Nyberget area and the Kvistaberget area were the main focal points of the regional
fieldwork.
The historic mineral occurrences within Nyberget revealed that most of the sulphide
mineralization present is related to carbonate replacement within the marble units. Several marble
units were identified with two large marble units containing sulphide mineralization in the form
of banded semi -massive to massive sulphides. Confirmation of these mineralized marble
horizons is important given their spatial relationship to significant polymetallic
mineralization in the Bergslagen Mining District. Additionally, quartz veins with abundant
chalcopyrite were also identified around historical mine workings, and are interpreted as distal to
massive sulphide mineralization or epigenetic mineralization.
At the Kvistaberget area an approximate northeast trending felsic and mafic volcanic sequence
was observed. Both the felsic and mafic units are at least partly extrusive in nature and in the case
of the mafic volcanics represent fire fountains proximal to a vent. This observation is important
as these specific rocks are often closely spatially associated with significant polymetallic
mineralization in the Bergslagen Mining District and elsewhere, as the metal bearing fluids
often use the same or parallel structures as the mafic magmas. Quartz-chalcopyrite veins of a
similar nature to Nyberget were also identified at Kvistaberget.
Several outcrops and historic showing were visited at the K ällberget area, which revealed two
outcrops with semi-massive to massive pyrrhotite-dominated sulphide mineralization with
associated strong alteration. The southernmost outcrop is related to a contact between laminated
felsic rocks and more mafic units, whereas the northeastern showing exhibits distinct skarn
alteration.
The lithologies mapped at the Uvberget area are dominated by banded, clastic felsic volcanic
rocks striking approximately northeast. A locally well -developed foliation of more than 45
degrees to the bedding was observed, which suggests a possible location close to a fold hinge.
Mapping found indications of an extrusive origin of the basalts (possible pillow basalts), as well
as possible small fragments indicat ing a clastic extrusive setting. Finally, two large, angular
boulders of impure marble observed in the area might indicate the presence of another unmapped
marble horizon further to the north or northwest.
Rock samples have been sent to ALS Geochemistry in Malå, Sweden for multi-element analysis.
