VANCOUVER, BC, March 10, 2022 /CNW/ - Norra Metals Corp.
("Norra" or the "Company") (TSXV: NORA) (Frankfurt: 1KO) (OTC: NRRMF) is pleased to
announce that the company has defined one drill-ready target and
five high-priority targets at Bleikvassli property, as a result of
the previous historical data compilation and integration.
The targets were selected based on results obtained from data
such as NGU's (Norwegian Geological Survey) bedrock geochemical
survey, several geophysical surveys and historic core drilling. The
latter with special focus on a portion of the full down dip
extension of Bleikvassli deposit defining a drill-ready target
(Figures 2 and 3). The location of the targets is represented in
Figure 1 as well as most relevant sampling assays obtained and
conductors detected by several geophysical methods. Some of those
samples grades include up to 12.52% Cu; 35.51% Zn; 17.79% Pb;
80.6 g/t Ag and 744ppb Au. The geological, geochemical
and geophysical surveys reported herein are historical in nature
and not to be relied upon by the reader. A qualified person has not
done sufficient work on behalf of the Company to verify the results
of these historical exploration programs. While the historical
exploration programs should not be relied upon, the Company
believes the historical results provides an indication of the
potential of the property and is relevant to any future exploration
programs.
Bleikvassli Property
The Bleikvassli project consists
of six contiguous exploration licenses encompassing 6,000
hectares.
The project benefits from excellent infrastructure including
paved roads and rail access as well as a nearby labor force located
50 kilometers away in the industrial town of Mo-I-Rana, which
provides access to a deep water port and regional airport.
The property includes the past-producing Bleikvassli mine. The
operations at Bleikvassli began in 1957 and lasted until 1997,
producing in total more than five million tonnes of
zinc-copper-lead-silver. According to the Norwegian Geological
Survey (NGU), historical resources remaining at the time of the
mine closure totaled 720,000 tonnes grading 5.17% Zn, 0.27% Cu,
2.72% Pb, 45g/t Ag, 0.2g/t Au. No exploration has been done since
late 90's.
Mineralization at Bleikvassli consists of lenses of base metals
massive and semi-massive sulphide mineralization which locally
grade into more copper and gold-rich compositions. The geological
setting and mineralization suggest a Sedex/VMS type of deposit.
The historical data compiled is stored at NGU data repository
and in the archives at the mine site. It consists of geological
plan maps, geological sections, maps of underground workings,
drilling logs and core assays and a large amount of technical
reports. The mine compilation data gathers 1,080 drill holes, 25
kilometers of underground workings divided by several levels and
exploited ore panels (Figure 2). The Company cautions that it is
not aware of the key assumptions, parameters or methods, including
data verification techniques used by the NGU to prepare these
historic estimates and has not done sufficient work to verify these
published resource numbers and therefore is not treating the
historical estimates as current mineral resources.
Bleikvassli mine related targets:
Down dip of Bleikvassli mineralization – Drill-ready
target
The down dip/down plunge of the Bleikvassli
mineralization remains open at full strike of the mine for over
1,200m, and also at depth. Several
base metal drill intercepts down dip of the existing mine workings
(figure 2 and 3). Those intercepts are spread in a volume defined
by approximately 400m strike length
and between elevations 170m to
50m with thickness varying from few
meters up to 15m. Hole DH19-97
intersected 18.20m grading
6.59% Zn; 0.25% Cu; 2.38% Pb and 21.36 g/t Ag, and hole
DH10-97 intersected 28.0m
grading 3.86% Zn; 0.67% Cu; 2.15% Pb and 43.54 g/t Ag,
including 12.0m grading
4.38% Zn; 0.81% Cu; 2.18% Pb; 45.23 g/t Ag and 0.57g/t Au
(see table in figure 1 for more results). The down dip extension at
the central part of the deposit constitutes a drill-ready target
with a significant size when compared with the exploited mine
(Figure 2). It is the Company's intention to drill this target in
the first phase of near-mine exploration.
Kjøkkenbukta
The Kjøkkenbukta target is a result of a
middle 90's modified-TFEM survey (filtering the graphite effects on
conductivity) done in two mineralized lenses ("Nordmalm")
outcropping at the northeast underground end of the mine. The
results obtained defines two strong conductors connected to the
Nordmalm lenses with approximately 800m length at an estimated depth of
100-150m from surface (figure 1 and
3). From the total length of the conductor, the northeast
600m edge remains untested and the
200m portion closer to the mine were
partially investigated by drilling with several mineralized
intercepts.
Rapliasen
Rapliasen target is located at northeast of
the Bleikvassli mine along the same geological horizon. It consists
of a cluster of conductors with 1,500m length identified by geophysical surveys
and limited testing by drilling (only 4 drill holes not exceeding
20m depth each). Those conductors are
in many cases coincident with Cu±Zn±Pb soil anomalies at surface.
The conductors of Rapliasen and Kjøkkenbukta, are aligned and in
the same geological stratigraphic horizon of the mine defining a
conductive corridor of about 2.5km mostly untested.
Bleikvassli South
(Figures 1 and 3). The southern
extension of the mine's productive geological horizon constitutes a
target as the mineralization ends abruptly at the south end and no
modern exploration methods were applied since the 90's.
Regional targets:
Brunnesbekken
This target consists of a Cu-Zn-Pb
discontinuous mineralization intersected by 90's historical
drilling campaign as a consequence of a geophysical survey done in
the area which detected an anomaly at depth. The drill holes
intersected anomalous base metal grades with the most significant
found in BR1-97 with 145.50-149.70
m (4.2 m): 1.22% Cu; 1.17% Zn;
0.14% Pb that includes 145.50-148.30m (2.8m):
1.45% Cu; 1.59% Zn; 0.12% Pb (Figure 1). The mineralization
found from drilling is mainly situated at the same stratigraphic
level at the contact between two different units as in the
Bleikvassli mine and can be followed for 250m along strike. Brunnesbekken target intends
to follow-up the investigation along the same contact to northwest
and at deeper levels where Cu-ratio distribution indicates a more
proximal character of mineralization.
Kongsfjellet
This target consists of two alignments,
one with 1.1km northwest and the other with 600 m running towards northeast, both
materialized by small occurrences of disseminated mineralization at
surface. Surface bedrock sampling done by NGU on some of those
prospects obtained strongly anomalous grades of base metal and
gold. Some of those grades include up to 12.52% Cu; 35.51% Zn;
17.79% Pb; 80.6 g/t Ag and 744ppb Au (see Figure 1 for sample
location and assay results).
Mr. Paulo Nuno de Sá Caessa, EurGeol., VP Exploration,
stated, "We consider the targets of Bleikvassli property of extreme
importance for the growth of the Company as they represent
high-priority targets amongst the company portfolio. Our intentions
for future exploration work are to be focused on developing the
highest priority targets in the area such as the investigation of
down dip extension of the Bleikvassli mine by drilling and the
further investigation of north and south extensions along the same
productive geological horizon as the Bleikvassli mineralization by
geophysical surveys. These targets represent favorable settings to
expand the known mineralization at Bleikvassli mine. It is also our
intention to develop the remaining prospects with both airborne and
ground geophysics to define additional drill targets."
