VANCOUVER,
BC , Sept. 30, 2020
/CNW/ - District Metals Corp. (TSXV: 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 alteration minerals associated
with polymetallic mineralization in the Bergslagen District. Also,
a tremolite 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 style 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 the 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 geometry of the rock
units, and determine relationships between the mineralization and
the stratigraphy and structure. The 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) appear 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 layering 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 western 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
Källberget 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 indicating 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.
