GEOPHYSICS AT THE RÅNA NICKEL-COPPER-COBALT PROJECT,
NORWAY
Vancouver, BC / TheNewswire / July 21, 2023 / Global Energy Metals
CorporaCon TSXV:GEMC | OTCQB:GBLEF | FSE:5GE1 (“Global Energy
Metals” , the “Company” and/or “GEMC”) , a mul’-jurisdic’onal, mul’-
commodity cri’cal mineral explora’on and development company focused on
growth-oriented ba<ery metal projects suppor’ng the global transi’on to
clean energy, is pleased to report that its strategic partner, Kingsrose Mining
Limited (“Kingsrose”), has completed the acquisi’on and interpreta’on of
ground based electromagne’c (EM) and magnetotelluric (SPARTAN MT)
geophysical surveys at the Bruvann Mine area within the Råna Project,
Norway (Figures 1 and 2). In addi ’on, a ground-based MT survey at the
Rånbogen prospect and MobileMT survey over the en ’re Råna intrusive
complex are now complete and results will be interpreted over the coming
weeks.
Highlights
•Strong apparent conduc’ve bodies with the poten’al for massive sulphide
mineraliza’on have been iden’fied from SPARTAN MT and EM data in three
locali’es proximal to the past-producing Bruvann Mine (Figures 2 to 5):
•West-southwest and down plunge of mined-out massive sulphide
mineralisa’on at Bruvann Mine (Target “Bruvann 01”) (Figure 3).
•West and down plunge of disseminated mineralisa’on which remains
open at Bruvann Mine, as indicated by historical drill results including
20.4 metres at 0.45 % Ni (BG-64-01), 18.3 metres at 0.48 % Ni
(bh-1144-02), 23.0 metres at 0.42 % Ni (bh-1143-02) and 11.4 metres
at 0.67 % Ni (BG-39-01) (Target “Bruvann 02”) (Figure 4).
•Northeast of the Bruvann Mine located at the contact between
country rock and gabbronorite intrusive, locally underlying a len’cular
perido’te dyke mapped at surface (Target “Bruvann 03”) (Figure 5).
•Drill tes’ng of the targets is underway to inves ’gate the poten’al for
massive sulphide nickel-copper-cobalt mineralisa’on associated with the
conduc’ve bodies.
•An extension of the EM geophysical survey and downhole EM is expected to
be conducted in late July 2023 to further de fine the targets and provide
addi’onal confidence in future drill targe’ng.
Andrew Tunningley, Kingsrose Head of ExploraCon, commented:
“The ini’al geophysical results at Bruvann are highly encouraging in demon-
stra’ng the presence of previously uniden’fied, strongly conduc’ve bodies
proximal to the mined-out mineralisa’on. Our aim is to validate the geophysi-
cal interpreta’on with drilling and follow up detailed geophysics and work to-
wards discovery of new zones of massive sulphide nickel-copper-cobalt miner-
alisa’on.”
Fabian Baker, Kingsrose Managing Director, adds:
“Following the MT and EM results reported today, we are eagerly awai’ng the
final results and interpreta’ons from MT data at the Rånbogen prospect, as
well as the MobileMT data which covers the en’re Råna intrusion. Our sys-
tema’c approach to explora’on is designed to methodically explore the large
and prospec’ve landholding which Kingsrose has consolidated at Råna.”
Discussion of Results
Kingsrose has completed ground based MT and EM surveys at the Bruvann
Mine area, with the aim of modelling the local geology and genera’ng explo-
ra’on targets associated with zones of elevated conduc’vity which may rep-
resent massive sulphide mineralisa’on. Following is a discussion of the tech-
niques employed, and an interpreta’on of the results and targets generated.
Magnetotelluric Data
MT is an electromagne’c technique that maps resis’vity, to infer sub-surface
geology and iden’fy zones of low resis’vity (high conduc’vity) which may
correspond with massive sulphide mineralisa’on. MT is a passive technique
which uses natural sources of electromagne’c fields such as lightning and so-
lar flares and is a highly portable technology, capable of detec ’ng a large
range of frequencies, resul’ng in high quality data acquisi’on to great depths.
The MT survey at Bruvann was conducted using a rela’vely ’ght sta’on spac-
ing of 200 metres, with the aim of mapping to at least 1000 metres below sur-
face. A three-dimensional model of resis’vity was produced to aid interpreta-
’on of geology, structure and zones of poten’al massive sulphide mineralisa-
’on. Three zones of high conduc’vity have been observed in the Bruvann MT
data (Figure 2):
•Immediately south of the Bruvann Mine (Figure 2).
•West and down plunge from the Bruvann Mine, 650 metres below surface
(targets “Bruvann 01” and “Bruvann 02”) (Figures 3 and 4).
•One kilometre northeast of the Bruvann Mine at the contact between
gneiss wall rock and perido’te intrusive rock, from surface and extending to
over 1000 metres depth (“Bruvann 03”) (Figure 5).
Mined-out massive sulphide mineralisa’on occurred at the gradient between
very high and moderate conduc’vi’es (Figures 2 and 3). The observa’on that
massive sulphide mineralisa’on occurs at the gradient between very high and
moderate conduc’vi’es provides Kingsrose with an important vector for tar-
ge’ng other zones of massive sulphide mineralisa’on. Perido’te, which is the
main host rock to high tenor nickel mineralisa’on, has been modelled from
logging of historical drill holes and corresponds with the same MT gradient at
the Bruvann Mine. The remainder of the Bruvann Mine occurs as disseminat-
ed sulphide mineralisa’on which is not detectable by MT techniques and
does not appear as an anomaly in the MT data, however the disseminated
mineralisa’on is hosted predominantly within perido’te.
Linear, steeply dipping zones of very high conduc’vity occur in two areas:
south of the Bruvann Mine trending east to west, and north of the Bruvann
Mine trending northeast (Figure 2). These linear zones are inferred to repre-
sent graphi’c horizons within the gneiss wall rock and are lower priority tar-
gets. Graphi’c zones do occur proximal to massive sulphide mineralisa’on at
Bruvann, and clasts of graphite are commonly observed within the massive
sulphide, therefore the presence of graphi’c horizons proximal to the intru-
sive contact are considered a locally important control on mineralisa’on.
ElectromagneCc Data
EM surveys are used to iden’fy zones of high conduc’vity which may repre-
sent massive sulphide mineralisa’on. EM is an ac’ve technique where power
generators are used to create electromagne’c fields in the sub-surface. Mod-
elling of the data creates conduc’ve ‘plates’ , or tabular zones, which are
modelled to fit the EM data and aid geological interpreta’on for detailed drill
targe’ng. Three broad zones of high conduc’vity were modelled from the EM
data:
1.Immediately south of the Bruvann Mine, where the modelled plates
strike east-west over 800 metres and dip steeply south, coincident
with mapped graphite (modelled to a consistent value of around 2000
siemens). However, a sub-parallel plate west of the Bruvann Mine and
coincident with a narrow zone of nickel sulphide mineralisa’on drilled
historically represents an important explora’on target (Bruvann 01)
(Figures 2 and 4).
2.350 metres west of and down-plunge from the Bruvann Mine, at the
western limit of the EM survey. Three alterna’ve flat lying plates have
been modelled at depths between 350 and 1000 metres below sur-
face, and an extension to the EM survey to be<er define this target
(Bruvann 02) (Figures 2 and 4) is planned for late July 2023.
3.Northeast trending, steeply northwest dipping plates located one
kilometre northeast of the Bruvann Mine, parallel to the contact be-
tween gneiss and the gabbronorite intrusion (Figures 2 and 5). Whilst
graphite is mapped at surface in this area, a zone of complex EM
plates in the northeast is proximal to a mapped perido’te dyke within
the gabbronorite and is undrilled (Bruvann 03).
Target generaCon from EM and MT data interpretaCon
Geological mapping, interpreta’on of historical drill data and processing of
MT and EM geophysical data has resulted in the defini’on of three main tar-
get areas at Bruvann (Figure 2):
1.Bruvann 01: A strong, 400 by 600 metre MT conduc’ve body is locat-
ed west and down plunge of the mined-out massive sulphide mineral-
isa’on, which is blind at surface and has not been drill tested (Figures
2 and 3). An EM plate has been modelled coincident with the gradient
of the MT conductor and is proximal to narrow massive sulphide his-
torical drill intercepts of 1.1 metres at 0.9 % Ni from 278.4 metres and
0.1 metres at 2.7 % Ni from 299.5 metres (P-8-96), which are open in
all direc’ons (Figure 4).
2.Bruvann 02: The northern gradient of the above MT conductor is co-
incident with poorly constrained EM plates at the western extremity
of the survey area (Figures 2 and 4). This target is 350 metres west
and down dip of the Bruvann Mine where mineralisa’on is open, in-
cluding historical drill intercepts from underground drill sta’ons, for
example 20.4 metres at 0.45 % Ni (BG-64-01), 18.3 metres at 0.48 %
Ni (bh-1144-02), 23.0 metres at 0.42 % Ni (bh-1143-02) and 11.4 me-
tres at 0.67 % Ni (BG-39-01)
3.Bruvann 03: An MT conductor coincident with a modelled EM plate
occurs at the contact between gneiss and a perido’te dyke hosted in
gabbronorite, located one kilometre northeast of the Bruvann Mine
(Figures 2 and 5). The conductor con’nues from surface to over one
kilometre below surface and drilling will test both the EM plate and
the gradient between very high and moderate conduc’vi’es. This is
inferred to represent a zone of poten’al massive sulphide mineralisa-
’on at the contact between perido ’te and gneiss wall rock with
graphite horizons.
Follow up work to test the above targets will include diamond drilling as part
of the current program and an extension to the ground EM survey, due to
commence at the end of July 2023. The purpose of this is to be<er define the
loca’on and orienta’on of the Bruvann 02 target prior to drill tes ’ng.
Downhole EM surveys will be completed at the same ’me as the extension to
the ground EM, to generate and refine addi’onal drill targets.
