Results of the 2022 Field Programme at the Disko-Nuussuaq
Ni-Cu-Co-PGE-Au Project, Central West Greenland
Bluejay Mining plc (AIM: JAY) ('Bluejay', the 'Group', or the
'Company'), the AIM, FSE-listed and OTCQB traded exploration and
development company with projects in Greenland and Finland, is
pleased to announce the results of the 2022 field programme (the
'Programme') at its Disko-Nuussuaq nickel-copper-cobalt-platinum
group elements-gold ('Ni-Cu-Co-PGE-Au') Project ('Disko-Nuussuaq'
or the 'Project'), on behalf of Nikkeli Greenland A/S ('Nikkeli'),
the Greenland registered Joint Venture ('JV') company created by
Bluejay and its JV partner KoBold Metals ('KoBold').
The geochemical, geophysical, and geological data from the 2022
exploration campaign (see Bluejay RNS dated: 10 October 2022 ) has
now been fully integrated with existing data and interpreted by
KoBold's technical team utilising their proprietary artificial
intelligence ('AI') and machine learning ('ML') platforms.
Significantly more data was gathered during 2022 than originally
expected which has prolonged the time required to analyse the new
datasets and incorporate these with historical data and
observations. The resulting interpretation has allowed the JV to
rank and prioritise targets and will form a strong basis for
decisions on future field and drilling programmes.
Highlights
-- Geophysical surveys support existing targets and have
identified new areas of interest:
o In addition to known targets, the Falcon(R) Airborne Gravity
Gradiometer ('AGG') surveys have identified an additional 9 strong
gravity (+/- magnetic) anomalies that may represent previously
unrecognised mafic-ultramafic intrusions of comparable size to the
host intrusions of many world-class magmatic Ni-Cu sulphide
deposits.
o A strong early-time SAMSON and HeliSAM electromagnetic ('EM')
anomaly, c. 600 x 900 metres ('m') in size has been identified
within the Qullissat intrusion at shallow depth. A mid-time HeliSAM
EM anomaly has been identified in the Aaffarsuaq Valley at a
modelled depth of 400 to 800m. A modest late-time SAMSON anomaly,
c. 600m in length has been identified at the Igdlukunguaq target
along strike of the 28-tonne Igdlukunguaq massive sulphide bounder
(grading 6.86% Ni, 3.71% Cu, 0.55% Co and 2.0 grams per tonne
('g/t') combined Pt and Pd).
-- Geochemical surveys have provided independent verification of
geophysical targets:
o Anomalous Mobile Metal Ions ('MMI') soil geochemistry for
nickel ('Ni'), copper ('Cu'), cobalt ('Co'), platinum ('Pt')
palladium ('Pd'), gold ('Au'), selenium ('Se'), tellurium ('Te')
and chromium ('Cr') at Aaffarsuaq Valley, Qullissat and
Igdlukunguaq, support the presence of magmatic sulphide
mineralisation and provide further independent validation of
geophysical drill targets at these localities.
o Rock samples from the Qullissat intrusion provide geochemical
evidence that this partially outcropping intrusion reached sulphur
saturation, further increasing the Company's ranking of existing
geophysical drill targets associated with this locality.
-- Operational highlights, expenditure, and new licence
application:
o Under Stage I of the JV agreement, KoBold had a commitment to
sole-fund a minimum of US$3.4 million in exploration expenditure
during 2022. KoBold opted to increase their 2022 expenditure
substantially beyond their earn-in commitments. The additional
expenditure by KoBold allowed the JV to collect significantly more
geophysical and geochemical data than was originally planned.
o Total exploration expenditures for Nikkeli's Disko-Nuussuaq
licences during 2022 have been approved by the Mineral Licencing
and Safety Authority ('MLSA'), Government of Greenland. The
approved expenditures cover both the 2022 and 2023 licence
commitments.
o Bluejay fulfilled the role of Field Operations Manager during
the 2022 field programme and for this role received a JV
expenditure-based management fee as well as reimbursement of
Bluejay employee salaries. Bluejay also receive an additional
income from Nikkeli for the rental of its purpose-built modular
exploration camp at Qullissat, Disko Island.
o As the majority partner of the JV, KoBold has elected not to
proceed with any field programme at Disko-Nuussuaq in 2023. Desktop
studies and modelling of existing datasets is ongoing.
o Under Stage II of the JV, KoBold is required to spend US$11.6
million on drilling related expenditure or drill 15 pre-agreed
diamond drill holes within the licence areas by 31 December 2024
(see Bluejay RNS dated: 9 August 2021 ). Should KoBold not complete
its Stage II commitments, 2.0% of the JV company and thereby
control will revert to Bluejay with both parties subject to
continuing standard dilution methodology.
o An application for a new Mineral Exploration Licence ('MEL')
totalling 116.6 square kilometres ('sq-km') has been submitted by
Nikkeli to the MLSA, Government of Greenland. The new MEL will
provide Nikkeli with a buffer around its existing licences and
secures a continuous land position along the drill accessible north
coast of Disko Island where the Company has several high-priority
drill targets.
Chief Executive Officer of Bluejay Mining plc, Dr Bo Møller
Stensgaard, commented:
"We're delighted to report the results of our first JV
exploration campaign with KoBold, which has considerably advanced
our understanding of several key targets at Disko-Nuussuaq, most
notably at Qullissat, within the Aaffarsuaq Valley and along the
northern coats of Disko Island. The large volume of new data
collected in 2022 represents one of the most aggressive and
extensive data-gathering campaigns ever completed at
Disko-Nuussuaq.
"Results from the in-depth analysis of the 2022 data continue to
excite us and when integrated with historical data and
observations, provide us with a very strong foundation for planning
future campaigns. Not only has it presented us with a greater
ability to evaluate our degree of confidence on already identified
drill targets - it has also generated new targets and areas of
interest. We now have a high degree of confidence in several of our
drill targets and look forward to testing these. At the same time,
it should be emphasised that our Disko-Nuussuaq Project truly
represents a district-scale opportunity of significant magnitude
and that there are undoubtably still new targets to be found within
our licences, as well as known prospective areas that have not yet
been fully assessed or covered with new data.
"The analysis and interpretation of the extensive 2022 datasets
by KoBold's team of geologists and data scientists is largely
complete. We acknowledge the desire of our JV partner to access, in
its entirety, the district-scale play and the need to rank and
prioritise targets ahead of future work. We continue to progress
the Project in line with the JV Agreement under which KoBold must
spend US$11.6 million in drilling related expenditure or 15
pre-agreed drill holes by the end of 2024.
"The results presented in this press release are testimonial to
the scale, number of potential targets and opportunity for
discovery that the Disko-Nuussuaq Project represents. Discovering
the next Noril'sk remains the holy grail for nickel explorers -
we're confident that we are well positioned with the right licence
areas, in the right district, to make a globally significant
Ni-Cu-Co discovery at Disko-Nuussuaq."
Vice President Exploration of Bluejay Mining plc, Joshua Hughes,
commented:
"One of the primary challenges in targeting magmatic sulphide
deposits is the absence of a footprint beyond their host
intrusions. Exploring for this style of deposit therefore requires
diligent and systematic geophysical and geochemical evaluation,
especially when exploring beneath cover. Building upon more than 35
years of legacy commercial data, a wealth of scientific knowledge
for the region and applying a minerals systems framework to our
exploration, we continue to strengthen and upgrade the geological
model for Disko-Nuussuaq. Our targeting is becoming ever more
refined and focussed ahead of future drilling campaigns. With c. 50
personnel on-site last summer, 2022 was the largest field campaign
we have conducted at Disko-Nuussuaq to-date.
"Work at Qullissat has further validated the intrusion as a
high-priority drill target. We have now demonstrated the presence
of a shallow early-time EM anomaly in the HeliSAM and SAMSON
surveys that exactly matches the location of historical EM and
magnetotelluric ( 'MT ') anomalies. These anomalies are bound by a
large gravity high identified in the Falcon(R) AGG survey that
indicates that we may be dealing with a substantial mafic intrusion
(modelled up to 8 kilometres ('km') long, 450m wide and up to 400m
thick), comparable in size to intrusions known to host major
magmatic sulphide deposits globally. The new geochemical data for
Qullissat intrusion provides another layer of confidence to this
target: rock samples clearly show that the intrusion reached
sulphide saturation, a critical geological process in the formation
of magmatic sulphide deposits, and soil geochemistry by two
separate analytical methods has revealed consistent geochemical
anomalies in the soils surrounding this partially outcropping
intrusion. Minor drilling by Falconbridge in the early 1990's did
not test these EM and MT anomalies but did encounter a gold
mineralised native iron cumulate at the base of the intrusion,
which returned up to 38.3 g/t gold in a magnetic concentrate ([1])
. We know from other locations on Disko-Nuussuaq that magmatic
sulphides and mineralised native iron cumulates can occur within
the same intrusions and within individual lava flows. The
widespread occurrence of native iron cumulates is unique to
Disko-Nuussuaq and provides us with an additional exploration
target, particularly for gold and PGE.
"We're also excited about our deeper targets in the Aaffarsuaq
Valley, where the HeliSAM surveys again support the presence of a
conductive body that corresponds spatially to historical EM and MT
anomalies. As well as progressing our existing targets, we continue
to identify new targets within our licence areas through
cutting-edge exploration technologies. For example, the 2022 Falcon
(R) AGG surveys identified a suite previously unknown gravity (+/-
magnetic) anomalies along the northern coast of Disko Island, the
inner parts of the Kuugannguaq Valley and at Serfat that are of
sufficient dimensions to be considered of commercial interest as
probable mafic-ultramafic intrusions. These new anomalies warrant
further characterisation through additional UAV-borne magnetics,
ground electromagnetic and/or gravity surveys and geochemical
sampling during future field campaigns. Related to this, there are
still highly prospective areas, e.g., in Hammer Dal, Kuugannguaq
Valley and Stordal on Disko Island and the Itilli and Serfat areas
at Nuussuaq, which were not able to be assessed in detail during
the 2022 programme - all of which justify further exploration. The
abundance of robust targets speaks to the district-scale potential
that we recognise within our 2,903 sq-km Disko-Nuussuaq
Project."
Overview of the 2022 Field Programme and Contractors
2022 field activities at Disko-Nuussuaq targeted numerous areas
for massive Ni-Cu-Co-PGE-Au bearing sulphides using advanced
geophysical and geochemical exploration technologies,
including:
o 3,030 line-kilometres ('line-km') of high-sensitivity
fixed-wing Falcon(R) AGG, magnetic and LIDAR survey flown by
Xcalibur Multiphysics , Canada.
o 2,115 line-km of high-resolution UAV magnetics surveys
undertaken by EarthEx Geophysical Solutions Inc , Canada.
o 699 SAMSON deep-penetrating ground EM stations undertaken by
Discovery International Geophysics , Canada in collaboration with
Gap Geophysics , Australia.
o 1,068 line-km of HeliSAM airborne EM undertaken by Discovery
International Geophysics, Canada in collaboration with Gap
Geophysics, Australia.
o Three multibeam hydrographic bathymetry surveys totalling
37.25 sq km were undertaken by HydroCharting ApS , Denmark.
o 3,572 geochemical samples (comprising rock, soil, and stream
sediment and heavy mineral concentrate samples).
o 60 rock samples collected for petrological studies.
o 134 rock samples collected for petrophysical analysis by
EarthEx Geophysical Solutions Inc., Canada.
Results of the Geophysical Surveys:
Falcon(R) AGG Surveys
Xcalibur Multiphysics's proprietary Falcon(R) AGG system has
been jointly developed by Xcalibur Multiphysics, BHP, and Lockheed
Martin over the last 20 years. This has led to the only commercial
AGG system that is specifically designed to deal with the rigours
of high-resolution data collection in the dynamic airborne
environment. The state-of-the-art system uses extremely sensitive
accelerometers to produce low-noise, high-resolution gravity data
from an airborne platform, providing several key advantages over
other standard Full Tensor Gradiometer ('FTG') systems. The
resulting gravity data provides an image of the geology based on
density variations in the underlying rocks. It therefore provides a
useful geophysical tool to explore for the mafic-ultramafic
intrusions that may host massive sulphide mineralisation within
Nikkeli's licence areas.
A total of 3,030 line-km was completed over nine survey areas on
Disko Island and the Nuussuaq Peninsula (Figure 2). Eight of the
surveys were flown with a flight line spacing of 200m and one with
a 150m line spacing, with a nominal 100m terrain clearance height
on all surveys. Geophysical instruments installed in the Cessna
C209B turbo prop aircraft used to conduct the surveys included the
Falcon(R) AGG Kepler system and caesium Scintrex CS-3
magnetometer.
Detailed modelling of the AGG and magnetic data was completed
in-house by KoBold. Several positive gravity anomalies have been
identified associated with known targets (e.g., at Qullissat and
within the Aaffarsuaq Valley). Significantly a number of these are
coincident with conductive bodies identified in earlier EM surveys
and now further supported by independent geochemical proxies.
Outside of the existing targets, the Falcon(R) AGG surveys have
also identified nine previously unrecognised large gravity highs
(at Serfat, the inner parts of the Kuugannguaq Valley and along the
northern coast of Disko Island) that have sufficient dimensions to
be of interest as intrusions which could host magmatic sulphide
mineralisation. Several of the gravity highs are coincident with a
strong magnetic response. However, none of these new gravity
anomalies currently have EM coverage. Follow up work including
detailed ground gravity and EM surveys are planned as part of
future programmes to refine and better characterise the gravity
anomalies.
HeliSAM and SAMSON EM Surveys
The dual ground and airborne EM programme, provided by Discovery
International Geophysics in collaboration with Gap Geophysics
comprised of 699 SAMSON deep-penetrating ground EM stations and
1,068 line-km of HeliSAM airborne EM. HeliSAM is a Hybrid Transient
Electromagnetic ('TEM') technique that uses an inductive
ground-based transmitter loop in conjunction with a helicopter
towed caesium vapour total field magnetic sensor.
SAMSON uses a TM-7 receiver system to perform time-domain EM
surveys using a total field cesium vapor sensor. This allows the
system to operate at very low base frequencies needed for
determining the true late-time decay constant of a highly
conductive or deep target. During the Programme, Nikkeli switched
focus from HeliSAM to SAMSON to guarantee sufficient depth
penetration for the targets of interest. As SAMSON is a
ground-based technique it has a slower production rate compared to
HeliSAM. Therefore, planned EM surveys over Hammers Dal and the
Kuugannguaq Valley were not undertaken but are planned during
future field campaigns.
Results of the HeliSAM and SAMSON surveys:
(1) HeliSAM and SAMSON loops QU02: clear and discrete early-time
(channels 1-10 in HeliSAM and SAMSON) EM anomaly has been
identified within the Qullissat intrusion ([2]) on the northern
coast of Disko Island. Simulated response models indicate that the
conductive body is shallow (110m +/- 100m), c. 600 x 900m in
dimension and c. 25 m thick. The current working model is
coincident with the modelled depth of an EM anomaly identified in a
GeoTEM airborne survey flown in 1992.
An Titan24 direct current resistivity and induced polarisation
('DCIP') and MT survey carried out by Quantec Geoscience in 2003
for earlier operator, Vismand Exploration, indicates a strong
conductivity anomaly at around 570m directly below the shallower EM
anomaly identified in the HeliSAM and SAMSON surveys in 2022. Both
this target and the aforementioned shallower target remain
undrilltested.
(2) HeliSAM loops AF03 and AF04: broad, smooth mid-time
(channels 15-20 in HeliSAM) EM anomaly has been identified in the
Aaffarsuaq Valley on the Nuussuaq Peninsula. Modelling of this
anomaly indicates a deep (c. 800m to centre and c. 400m to the top)
and weakly conductive body.
Notably this is spatially coincident with anomalies identified
in several other geophysical datasets including the aforementioned
Titan24 DCIP and MT survey by Vismand Exploration and an audio
frequency magneto-variational ('AFMAG') survey using the Z-Axis
Tipper electromagnetics ('ZTEM') system flown in 2012 by Avannaa
Resources. These anomalies occur within a large gravity high
identified a historical Carson gravity survey flown in 1996 for
GrønArctic as part of a hydrocarbon exploration programme. Vismand
Exploration attempted to drill test the EM and MT targets in the
Aaffarsuaq Valley but failed due to geotechnical and gas related
issues. Therefore, these targets remain undrilltested.
(3) Other HeliSAM and SAMSON loops: As earlier reported (see
Bluejay's press release dated: 10 October 2022 ), a modest
late-time EM anomaly, c. 600 m in length was identified in the
SAMSON data over the Igdlukunguaq target. However, the EM response
at this locality is just above noise levels. Therefore, removal of
noise from the data in collaboration with GAP Geophysics and
further parametric modelling of this target by KoBold is ongoing.
Significantly, the anomaly is located along strike of the 28-tonne
Igdlukunguaq high-grade massive sulphide bounder (see "About the
Disko-Nuussuaq Project" section later in this press release).
No significant EM anomalies have been identified in the
remaining loops. The EM responses in these loops is well-explained
by simple background geological models with no conductive bodies in
the subsurface.
UAV-borne Magnetics Surveys
2,115 line-km of high-resolution UAV magnetics surveys
undertaken by by EarthEx Geophysical Solutions over four survey
areas on Disko Island and the Nuussuaq Peninsula (Figure 3). The
surveys were flown with a target terrain clearance of 25 m and 50 m
line spacing. To conduct the survey, a cesium vapor magnetometer
and necessary navigation instruments were mounted on the DJI
Matrice Pro 600 UAV platform.
Hydrographic Bathymetric Surveys and Photogrammetric Survey
To optimise forward looking logistics, Nikkeli undertook three
multibeam hydrographic bathymetric surveys totalling 37.25 sq-km
(Figure 4) covering key marine access points on Disko Island and
the Nuussuaq Peninsula. This will provide a safe approach for
ocean-going vessels and barges to mobilise and demobilise drilling
and exploration equipment during future field seasons. A Sonic 2024
multibeam echosounder and sidescan sonar were used. The surveys
meet IHO Standards for Hydrographic Surveys (S-44).
To potentially reduce Nikkeli's dependency on helicopters and
overall fuel consumption, a photogrammetric survey of a historical
25 km long gravel road located in the Aaffarsuaq Valley on the
Nuussuaq Peninsula was undertaken. Minor repairs to this road would
allow vehicle access to several high-priority drill targets within
the Aaffarsuaq Valley and therefore improve exploration efficiency
and reduce related costs.

office, accommodation, and warehousing facilities) is located in
the city of Ilulissat where an international airport is currently
under construction. Bluejay are a well-known and trusted customer,
partner, and employer in the region.

Results of the Geochemical Sampling Programmes:
Soil Geochemistry
The soil sampling programme was carried out at Qullissat and
Igdlukunguaq on the northeast coast of Disko Island and in the
Aaffarsuaq Valley in the southern part of the Nuussuaq Peninsula
(Figure 8). A total of 1437 sample sites located along 45 profiles
were sampled over three key target areas.
Soil sampling is a fast and cost-effective method for
identifying anomalous areas and refining drillable targets
especially in the early stages of exploration. From each soil
sampling site, the sample was split into two identical samples that
were submitted to commercial laboratories for analysis; one sample
was submitted for MMI(TM) analysis, and the second sample was
submitted for bulk geochemistry using a four-acid digest. The
sampling and analytical procedures are described in detail at the
end of this press release.
MMI(TM) is a soil geochemical exploration tool that has been
repeatedly proven to be efficient for drill hole targeting and has
been successfully applied to find buried mineral deposits. SGS is
the owner and sole provider of MMI(TM) Technology. MMI(TM) is an
innovative analytical process that uses a unique analysis of metals
in soils and weathered materials. Target elements (e.g., Ni, Cu,
Co, Au, Pt, Pd) are extracted using weak solutions of organic and
inorganic compounds rather than conventional aggressive acid-based
digests. MMI(TM) solutions contain strong ligands, which detach and
hold the metal ions that were loosely bound to soil particles by
weak atomic forces. The extraction does not dissolve the bound
forms of metal ions. Thus, metal ions in MMI(TM) solutions are the
chemically active or 'mobile' component of the sample. This mobile
component may derive from the upwards migration of metal ions from
buried sulphide mineralisation, which accumulates in the
unconsolidated surface materials (e.g., soil or glacial till). As
these mobile, loosely bound complexes occur in very low
concentrations (i.e., parts per billion ('ppb'), elemental
determinations are made by conventional or cell-based Inductively
Coupled Plasma Mass Spectrometry ('ICP-MS'). The 2022 MMI(TM) data
builds upon an detailed orientation study of using MMI(TM) and SGH
(Spatiotemporal Geochemical Hydrocarbons), completed by Bluejay at
Disko-Nuussuaq in 2019 (see Bluejay RNS dated: 04 February 2020
).
Anomalous MMI(TM) soil geochemistry for Ni, Cu, Co, Pt, Pd, Au,
Te, Se, and Cr in both the 2019 and 2022 datasets (Figures 9 to 17)
at Aaffarsuaq Valley, Qullissat and Igdlukunguaq support the
presence of magmatic sulphide mineralisation and provide further
independent validation of Nikkeli's geophysical drill targets at
these localities. Note that the MMI(TM) in Figures 9 to 17 are
plotted as response ratios relative to a median value. Localised
median values are used to reflect differences in local geology
between survey areas. Given the wide spacing of sampling profiles,
further MMI(TM) sampling is planned as in-fill between anomalous
profiles in the Aaffarsuaq Valley as part of future campaigns.
Soils surrounding the Qullissat intrusion on the northern coast
of Disko Island, returned consistent geochemical anomalies in both
the MMI(TM) and four acid digest soil geochemistry. The soils
surrounding the historical 28-tonne Igdlukunguaq massive sulphide
boulder (see "About the Disko-Nuussuaq Project" section later in
this press release) did not return any significant anomalism,
supporting Bluejay's earlier interpretation that the boulder is not
in-situ. The boulder, which was discovered adjacent to an
outcropping mafic dyke was assumed by earlier operators to be
in-situ, leading to Falconbridge drill testing the dyke. Several
anomalies in historical geophysical datasets up hill of the
Igdlukunguaq boulder are considered by the Company as good
candidates for the original source of the mineralisation.
Stream Sediment Geochemistry
The stream sediment sampling programme was carried out at
throughout Nikkeli's 2,903 sq-km licence areas with the densest
sampling in the Kuugannguaq and Aaffarsuaq valleys (Figure 8). A
total of 337 sample sites were sampled. For each sample site, two
separate samples were collected - one sample of panned heavy
mineral concentrate ('HMC') and one sample of the fine fraction of
<0.2 millimetres ('mm'). The sampling and analytical procedures
are described in detail at the end of this press release.
Whilst anomalous Ni values (i.e., elevated above the magmatic
trend) were identified at several localities, no coincident Ni and
Cu anomalism were identified. This suggests that there is only
minor potential for sub-cropping or outcropping magmatic sulphide
mineralisation at Disko-Nuussuaq - targets are almost certainly
blind and located at depth as indicated by numerous geophysical
datasets.
Rock Geochemistry
Rock sampling was primarily carried out as part of the
geological mapping programme, as well as from the logging of five
geological stratigraphic sections; a smaller number of rock samples
were collected during regional prospecting (Figure 8). A total of
347 rock samples were collected. The sampling and analytical
procedures are described in detail at the end of this press
release.
Most rock samples were unmineralised samples collected for
lithogeochemical studies. For 60 of the rock samples petrographic
polished thin sections were prepared. A detailed petrological study
by KoBold is ongoing. 134 rock samples collected for petrophysical
analysis (including magnetic susceptibility, Koenigsberger ratio
(for remanent magnetisation), nduced polarisation, resistivity
(galvanic), conductivity (inductive), density and porosity) by
EarthEx Geophysical Solutions Inc., Canada. These petrophysical
measurements build upon Nikkeli's existing petrophysical database
for Disko-Nuussuaq which is used to better constrain parameters
used in the modelling of geophysical datasets by KoBold's
geophysicists and data scientists.
Mineralised rock samples from the spoil heaps of the former
Igdlukunguaq boulder were collected for lithogeochemical
characterisation and returned maximum values of 5.78% Ni, 3.15% Cu
and 0.48% Co, hosted in massive sulphides. Rock samples from the
Qullissat sill on the northern coast of Disko Island, provide
geochemical evidence that this partially outcropping intrusion
reached sulphur saturation, which along with the surrounding soil
anomalism described above, further increasing the Company's ranking
of existing geophysical drill targets associated with this
intrusion.

About the Disko-Nuussuaq Project:
Disko-Nuussuaq Project comprises of five MEL's covering a total
of 2,903 sq-km located on the Nuussuaq Peninsula and Disko Island
in Central West Greenland. Nikkeli currently have an application in
progress for a new MEL on the north-east coast of Disko Island,
totalling 116.6 sq-km. The Project is located approximately 120 km
northwest of Ilulissat, the third largest city in Greenland (with
population of approximately 4700) and the educational, business and
administrative centre of Central West Greenland. The city benefits
from an airport, deep-water port facilities and a wide selection of
service providers. A new international airport is currently being
constructed and is scheduled for completion in 2025. Bluejay has
had a logistical hub comprising of an exploration office,
accommodation, and warehousing facilities in Ilulissat since 2016
that supports activities at its Disko-Nuussuaq and Kangerluarsuk
projects (Figure 1). The Company also has a modular exploration
camp for up to 40 personnel located at the abandoned coal mining
town of Qullissat on Disko Island.
The Disko-Nuussuaq Project is hosted within the West Greenland
Flood Basalt Province ('WGFBP'). The WGFBP is related to the
initial phase of continental breakup and initiation of seafloor
spreading of the Labrador Sea in the early Palaeogene. The province
is a well-recognised geological analogue to the Siberian Flood
Basalts of the Noril'sk Region, Siberia. This analogy was first
recognised by Cominco (now Teck) and provided the exploration
framework that has guided subsequent exploration. Subsequently
several peer-reviewed scientific studies (e.g., Lightfoot et al.,
1997; Lightfoot and Hawkesworth, 1997 ; Keays and Lightfoot, 2007 )
have highlighted the similarities between the geology of the
Noril'sk region (that hosts the Noril'sk-Talnakh
nickel-copper-cobalt-palladium mining district, the world's largest
nickel producing district) and the Disko-Nuussuaq region. It is
estimated based on the combined reserves, resources, and historic
production, that the total value of the ores in the Norilsk-Talnakh
district, at 2020 metal prices, exceeded US$1.4 trillion ( Barnes
et al., 2020 ).

Geological and metallogenic similarities between Disko-Nuussuaq
and Noril'sk include:
(1) Abundance of primitive, high-Mg olivine-rich magma (i.e.,
picrites and olivine basalts).
a. The Vaigat Formation at Disko-Nuussuaq is recognised as the
most voluminous picrite succession known on Earth, exceeding that
of Noril'sk.
b. The Disko-Nuussuaq region contains an unusually high
proportion of picrites, which constitute approximately one-third of
the total erupted volume and have been shown to represent almost
unmodified mantle melts ( Larsen and Pedersen, 2009 ; Pedersen et
al., 2017 );
(2) Fault control on magma conduits.
a. The three most important structures in the Disko-Nuussuaq
region are the Eastern Boundary fault system, the
Kuugannguaq-Qunnilik ('K-Q') fault system and the Itilli fault
system.
b. A clustering of mapped volcanic eruption sites along the N-S
orientated K-Q fault system, within Nikkeli's licence areas,
demonstrates its deep-seated nature as a preferred pathway for
magmas.
c. The K-Q and Itilli fault systems are largely covered by Nikkeli's exploration licences.
(3) Sulphur-rich sedimentary wall rocks.
a. The volcanics at Disko-Nuussuaq were emplaced through and
onto a substrate of 6-10 km thick sediments of the Nuussuaq
sedimentary basin of Cretaceous-Palaeocene age ( Dam et al., 2009 )
and Precambrian basement. The Nuussuaq Basin includes several
excellent sources of sulphur including black shales, coals, other
organic-rich sediments, as well as hydrocarbons. Occurrences of
basaltic ignimbrites have been attributed to the interaction of
magmas with hydrocarbons. Several petroleum seeps and stains are
known within Nikkeli's licence areas (e.g., Christiansen and
Bojesen-Koefoed, 2021 ).
(4) Repeated episodes of assimilation of siliceous crustal
rocks.
a. Lithogeochemical modelling including isotope geochemistry
reveals significant degrees of crustal assimilation within
contaminated units ( Larsen and Pedersen, 2009 ). Several of the
contaminated units constitute significant volumes (e.g., the Asuk
Member is known from northern Disko and southern Nuussuaq over an
area of >1000 sq km and up to 150 m thick; the Kûgánguaq Member
is known from northern Disko only and covers an area of >200 sq
km and up to 90 m thick).
b. Evidenced at Disko-Nuussuaq by the presence of silica
enriched volcanics including native-iron and graphite bearing
basalts, andesites and dacites, and graphite-bearing rhyolites
(e.g., Larsen and Pedersen, 2009 ; Pedersen et al., 2017 ).
(5) Sulphide segregation from the magmas.
a. The 28 tonne Igdlukunguaq boulder of high-grade massive Ni-Cu-Co-PGE sulphides (see below).
b. Accumulation of both Ni-Cu-Co-PGE sulphides and mineralised
native iron cumulates at the base of sills reported from several
localities within Nikkeli's licence areas.
c. Petrological work by a previous operator (Avannaa Resources)
identified spherical sulphide globules exsolving from silicate melt
in a highly nickel depleted welded tuff of the Kûgánguaq Member,
and graphitic andesites of the Asuk member (refer to Figure 19).
The globules are highly enriched in Ni and Cu (up to 6% and 3%
respectively) and considered to be representative of the exsolved
sulphide melt that is now accumulated beneath the thick volcanic
pile.
(6) Strong chalcophile and siderophile element depletion in
volcanic rocks.
a. Strong geochemical evidence (both whole rock
lithogeochemistry and mineral geochemistry) for chalcophile and
siderophile element depletion in contaminated lavas of the Vaigat
Formation.
b. Work by a previous operator (Avannaa Resources) on the
mineral chemistry of olivine and mass balance calculations for the
crustally contaminated and strong chalcophile and siderophile
element depleted Kûgánguaq Member (refer to Figure 19) indicates
that between 12-16 million tonnes of nickel is missing from this
depleted lava unit alone. This is inferred to be the result of the
segregation of sulphide melts from the magmas prior to eruption
within the sub-volcanic magma conduit systems.
c. Many other contaminated lava units exists (refer to Figure
19; Pedersen et al., 2017 , 2018 ) but these have not been studied
in sufficient detail to assess the amount of missing Ni, Cu and
PGE.
d. Contaminated units within the Vaigat Formation (see Figure
19) are estimated to account for approximately 545 cubic kilometres
('km(3) ') or 5.7% of the total volume ( Pedersen et al., 2017 ).
Nikkeli's exploration licences cover the majority of the crustally
contaminated and/or metal depleted units within the Vaigat
Formation, considered the most prospective units in which to find
Ni-Cu-Co-PGE-Au sulphide mineralisation.
(7) Proximity to magma conduit systems.
a. Outcropping mineralised sills (e.g., Qullissat) and
chonoliths ([3]) (e.g., Hammers Dal) are known within Nikkeli's
licences areas. Similar intrusive bodies are interpreted at depth
based upon various geophysical surveys - most notably within the
Kuugannguaq and Aaffarsuaq valleys.
b. Large-scale conductive bodies within the Kuugannguaq and
Aaffarsuaq valleys interpreted as intrusions, the largest being c.
10.0 km long and around 2.0 km wide and another being c. 4.8 km
long and 800m wide. Both are comparable in footprint to the
intrusions that host the world-class Noril'sk-Talnakh ore bodies in
Siberia.
c. Erosion is sufficiently deep to expose the base of the
volcanic pile on Disko-Nuussuaq and therefore the magmatic conduit
systems beneath the volcanics; positioned at a similar erosional
level to Noril'sk.
The volcanic stratigraphy on Disko-Nuussuaq is very well-defined
owning to continuous scientific research (e.g., mapping,
photogrammetry and lithogeochemistry) since the 1960's. The
volcanic succession can be divided into two major formations: the
Vaigat Formation and the Maligât Formation (refer to Figures 18 and
19). Nikkeli's licences are primarily focussed upon contaminated
members/units of the Vaigat Formation, considered by the Company to
be the most favourable lithologies in the region to host economic
magmatic sulphide mineralisation.
In addition to the magmatic sulphide potential at
Disko-Nuussuaq, the presence of ore-grade Ni-Cu-Co-PGE-Au
mineralised native iron as transported boulders up to 10 tonnes and
as thin cumulates at the base of sills and chonolith-like intrusive
bodies, provides Nikkeli with an additional exploration target
within the region. Nikkeli's licences cover most previously
recognised magmatic sulphide and native iron occurrences and
boulders.
Historical exploration at Disko-Nuussuaq dates back as far as
1870 when both native iron and Ni-Cu sulphide showings were first
recognised, including the discovery of the 28 tonne Igdlukunguaq
boulder of massive sulphide. The high-grade boulder is reported by
Falconbridge to have graded 6.86% Ni, 3.71% Cu, 0.55% Co and 2.0
g/t combined Pt and Pd ( Olshefsky, 1992 ), and grades of up to
10.3% Ni have been reported from smaller grab samples ( Pauly, 1958
) ([4]) . More than 35 years of modern exploration by companies,
including Cominco, Falconbridge, Vismand Exploration and Avannaa
Resources, as well as extensive government funded programmes by the
Geological Survey of Denmark and Greenland ('GEUS') and its
predecessor the Geological Survey of Greenland ('GGU'), has
resulted in a vast volume of geological, geochemical, and
geophysical datasets which support the presence of a mineralising
system(s) at Disko-Nuussuaq that may have resulted in a globally
significant accumulation of metals. It is estimated that this
multi-decade data
acquisition and field work represents up to US$50 million of
historical expenditure within Nikkeli's licence areas.

rocks and sediments on Disko Island and the Nuussuaq Peninsula. The

Deep conductive bodies that are interpreted to represent
mineralised intrusions were identified by Vismand Exploration in
2003-04, using a deep-penetrating Titan24 DCIP and MT surveys by
Quantec Geoscience, an industry leader in these geophysical
methods. The conductors were found in the Kuugannguaq and
Aaffarssuaq Valleys. Deep drilling to test one of these conductors
was attempted in 2007 by Vismand Exploration but failed to reach
the target depth due to geotechnical and gas related issues.
Therefore, the targets remain undrilltested. Bluejay commissioned
Quantec Geoscience to re-process the original Titan24 survey data
from six survey areas. There have been significant improvements
made to the processing and inversion streams for the Titan system
that benefited the evaluation and interpretation of the original
Disko surveys. The raw data from these types of surveys are
suitable for new processing techniques, utilising increased
computational power and interpretive techniques that have been
developed since the original survey. These improvements include
processing raw field data and the use of a joint inversion code for
the MT resistivity and DC resistivity data. The use of the new
joint inversion code can also help to improve near surface
resolution. MT surveys are a geophysical method which uses natural
time variations of the Earth's magnetic and electrical fields for
estimating the electrical resistivity - or conductivity - of the
sub-surface. Electrical conductivity is an important physical
property to measure in the search for massive sulphide
mineralisation. In 2012, Avannaa Resources commissioned Geotech
Ltd. to fly helicopter-borne ZTEM survey to further constrain these
targets.
Prior to the JV, Bluejay had undertaken several field campaigns
at Disko-Nuussuaq. This included multi-sensor UAV-borne surveys
(comprising magnetics, photogrammetric and hyperspectral imaging)
conducted in cooperation with the Helmholtz Institute Freiberg for
Resource Technology, Germany as a partner of the EU-funded EIT
RawMaterials MULSEDRO (MULti-SEnsor DROnes) project (e.g., Jackish
et al., 2022 ). In 2019, Bluejay carried out an MMI and SGH
geochemical orientation study, which for the first time
demonstrated the presence of metal anomalies coincident with
previously identified geophysically and geologically defined
targets. This study formed the basis for the larger MMI programme
completed by Nikkeli in 2022, reported in this press release.
Notes - Sampling, Assay and QAQC Procedures for Geochemical
Analysis
Rock sampling procedures and analysis: Rock samples were
submitted to ALS Geochemistry in Sudbury, Ontario, Canada for
sample preparation and geochemical analysis. After drying the rock
samples were crushed to >70% passing below 2 millimetres (ALS
method: CRU-31(TM)) and split using a riffle splitter (ALS method:
SPL-21(TM)). A 1 kilogramme split (or less depending upon the
original sample weight) was then pulverised to 85% passing below
-75 microns ('um') (ALS method: PUL-32(TM)).
The resulting pulps were then analysed using ALS Geochemistry's
complete characterisation package CCP-PKG01(TM). This comprised of
the following analyses: major elements (namely SiO2, Al2O3, Fe2O3,
CaO, MgO, Na2O, K2O, Cr2O3, TiO2, MnO, P2O5, SrO, and BaO) were
analysed by Inductively Coupled Plasma Atomic Emission Spectroscopy
('ICP-AES') after lithium borate fusion on a 0.20 gramme ('g')
aliquot (ALS method: ME-ICP06(TM)). Trace elements (namely Ba, Ce,
Cr, Cs, Dy, Er, Eu, Ga, Gd, Ge, Hf, Ho, La, Lu, Nb, Nd, Pr, Rb, Sm,
Sn, Sr, Ta, Tb, Th, Tm, U, V, W. Y, Yb, and Zr) were analysed by
Inductively Coupled Plasma Mass Spectrometry ('ICP-MS') following a
lithium borate fusion and acid dissolution on a 2g aliquot (ALS
method: ME-MS81(TM)). Volatile trace elements (namely As, Bi, Hg,
In, Re, Sb, Se, Te, and Tl) were analysed by ICP-MS after aqua
regia ([5]) digestion on a 0.5g aliquot (ALS method: ME-MS42(TM)).
Base metals and select trace elements (namely Ag, Cd, Co, Cu, Li,
Mo, Ni, Pb, Sc, and Zn) were analysed by ICP-AES after four acid
digestion ([6]) on a 0.25g aliquot (ALS method: ME-4ACD81(TM)).
Carbon and sulphur content were analysed by infrared ('IR')
spectroscopy (ALS methods: C-IR07(TM) and S-IR08(TM),
respectively). Loss on Ignition ('LoI') at 1000(o) C was also
analysed (ALS method: OA-GRA05(TM)). Any samples exceeding the
over-range threshold for nickel and copper were re-analysed using a
4-acid digest ICP-MS ore grade method (ALS methods: Ni-OG62(TM) and
Cu-OG62(TM)). Precious metals were not analysed.
Soil sampling procedures and analysis: Sample locations were
predefined and uploaded to the QField application on android field
tablets, with which sample metadata were entered. In case a sample
could not be collected at the exact predefined location, the sample
location was moved to a suitable location nearby and the
co-ordinates of this new location were entered into the QField app.
The line spacing for the soil sampling programme varied between 1-2
kms and 150 m. The sample spacing along the sampling lines was
generally 50m. A total of 1437 sites located on 45 sampling lines
were sampled. The samples were collected with an auger drill
equipment and a trowel (paint-free to avoid contamination). From
each sample site two identical samples were collected, each with a
preferred sample weight of 400g.
The first sub-sample was submitted to ALS Geochemistry in
Sudbury, Ontario, Canada for sample preparation and geochemical
analysis. After drying the sample was screened using a 180um screen
(ALS method: SCR-41(TM)). 48 elements (namely Ag, Al, As, Ba, Be,
Bi, Ca, Cd, Ce, Co, Cr, Cs, Cu, Fe, Ga, Ge, Hf, In, K, La, Li, Mg,
Mn, Mo, Na, Nb, Ni, P, Pb, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te,
Th, Ti, Tl, U, V, W, Y, Zn, and Zr) were analysed on a 0.25g
aliquot of the -180 um fraction by ICP-MS following four-acid
digestion (ALS method: ME-MS61L(TM)). This method provides ALS's
lowest detection levels from a four-acid digestion and is achieved
via proprietary ICP-MS methodology. The ultralow detection limits
are appropriate for the sample medium.
The second sub-sample was submitted to SGS Mineral Services in
Burnaby, Canada for sample preparation and geochemical analysis.
These were analysed using SGS' Mobile Metal ION enhanced package
(SGS method: GE_MMIME(TM)). There is no sample preparation or
drying. The analysis is done on a 50g sample split, and the
extracted solution is analysed by ICP-MS, providing determinations
for 55 elements (namely Ag, Al, As, Au, Ba, Bi, Ca, Cd, Ce, Co, Cr,
Cs, Cu, Dy, Er, Eu, Fe, Ga, Gd, Hg, In, K, La, Li, Mg, Mn, Mo, Nb,
Nd, Ni, P, Pb, Pd, Pr, Pt, Rb, Sb, Sc, Se, Sm, Sn, Sr, Ta, Tb, Te,
Th, Ti, Tl, U, V, W, Y, Yb, Zn, and Zr) in the ppb range.
Stream sediment and heavy mineral concentrate sampling and
analysis: Sample locations were predefined and uploaded to the
QField application on android field tablets, with which sample
metadata were entered. In cases where the streams were dry and
sampling was not possible, the location was not sampled, however
the sample location was sometimes moved to find a suitable location
for sampling and the co-ordinates of this new location were entered
into the QField app. Stream sediment samples were collected
preferably from suitable trap sites in the stream where material
would fall out of suspension and accumulate. Sample spots varied
from one to a few, depending on the availability of sediment in the
stream. In cases with sparse material sampling would be carried out
upstream from the first subsample, resulting in a composite
sample.
Before the start of the sampling all equipment was cleaned
downstream of the first sample location. The sampled material was
sieved through an 8-mesh sieve (2.5 mm aperture) and followingly a
70-mesh sieve (0.2 mm aperture). The middle fraction (0.2 to 2.5
mm) was panned in the field to a produce a HMC fraction and the
fine fraction (<0.2 mm) was kept as a separate sample. Two
samples were collected from each sampling site: one sample of the
HMC fraction with a minimum weight of 150g and one sample of the
fine <0.2 mm fraction with a minimum weight of 100g.
The HMC stream sediment samples were submitted to ALS
Geochemistry in Sudbury, Ontario, Canada for sample preparation and
geochemical analysis. After drying the samples were split using a
riffle splitter (ALS method: SPL-21(TM)). A split of up to 250g was
then pulverised to 85% passing below -75um (ALS method:
PUL-31(TM)). A 0.25g aliquot of the pulp was then analysed by
ICP-MS following the aforementioned ALS method: ME-MS61L(TM) (see
"soil sampling procedures and analysis" above). A 30 aliquot of the
pulp was analysed for platinum, palladium, and gold content by fire
assay with an ICP-MS finish (ALS method: PGM-MS23L(TM)).
The fine fraction (<0.2 mm) stream sediment samples were
submitted to ALS Geochemistry in Sudbury, Ontario, Canada for
sample preparation and geochemical analysis. After drying the
sample was screened using a 180um screen (ALS method: SCR-41(TM)).
44 elements (namely Ag, Al, As, Au, B, Ba, Be, Ca, Cd, Ce, Co, Cr,
Cs, Cu, Fe, Ga, Ge, Hf, Hg, In, K, La, Li, Mg, Mn, Mo, Na, Nb, Ni,
P, Pb, Pd, Pt, Rb, Re, S, Sb, Sc, Se, Sn, Sr, Ta, Te, Th, Ti, Tl,
U, V, W, Y, Zn, and Zr) were analysed on a 0.5g aliquot of the -180
um fraction by ICP-MS following aqua regia digestion (ALS method:
ME-MS41L(TM)).
Preliminary chemical analyses: An Olympus Vanta C Series
Portable X-ray fluorescence device ('pXRF') was used to provide
preliminary geochemical results of soil and rock samples in the
field base camp. After every 20(th) measurement a blank (glass disc
provided by Olympus) and a CRM (OREAS 684) were measured to track
pXRF performance. The instrument was also calibrated at the
beginning of each session.
QA/QC comments: The ALS (Sudbury) and SGS (Burnaby) preparation
and analytical labs are accredited to ISO 17025:2005 UKAS ref 4028
and have internal QA/QC programs for monitoring accuracy and
precision. ALS and SGS are both entirely independent of Bluejay,
Nikkili and KoBold. Bluejay and its subsidiaries operate according
to its rigorous internal Quality Assurance and Quality Control
('QA/QC') protocols, which are consistent with industry best
practices. For rock samples taken during the Programme, this
included the insertion of Certified Reference Materials ('CRMs')
into the sample stream at an insertion rate of one in every 20
samples. For soil samples taken during the Programme, this included
the insertion of CRMs into the sample stream at an insertion rate
of one in every 20 samples and field duplicates at a rate of one in
every 20 samples. For stream sediment samples taken during the
Programme, this included the insertion of CRMs into the sample
stream at an insertion rate of one in every 20 samples and field
duplicates at a rate of one in every 20 samples. The above
insertion rates are deemed by the Company to be appropriate for
this stage of exploration. The CRMs were supplied by Ore Research
and Exploration (OREAS), Australia. Internal QA/QC samples were
also inserted by the ALS and SGS analytical laboratories and have
been reviewed by the Company prior to release. No material QA/QC
issues have been identified with respect to sample collection,
security, and analysis for the 2022 Programme.

About Bluejay Mining plc
Bluejay is listed on the London AIM market and Frankfurt Stock
Exchange and its shares also trade on the OTCQB Market in the US.
With multiple projects in Greenland and Finland, Bluejay offers
both portfolio and commodity diversification focused on base and
precious metals in Tier 1 jurisdictions.
Bluejay, through its wholly owned subsidiary Disko Exploration
Ltd., has signed a definitive Joint Venture Agreement with KoBold
Metals to guide exploration for new deposits rich in the critical
materials required for the green energy transition and electric
vehicles (the Disko-Nuussuaq nickel-copper-cobalt-PGE Project).
Disko Exploration Ltd holds two additional projects in Greenland
- the 692 sq km Kangerluarsuk zinc-lead- silver project, where
historical work has recovered grades of up to 45.4% zinc, 9.3% lead
and 596 g/t silver; and the 920 sq km Thunderstone project which
has the potential to host large-scale base metal and gold deposits.
Bluejay also owns 100% of the fully permitted Dundas Ilmenite
Project under its subsidiary Dundas Titanium A/S in northwest
Greenland for which it will seek strategic alternatives.
In Finland, Bluejay currently holds three large scale
multi-metal projects through its wholly owned subsidiary FinnAust
Mining Finland Oy. The Company has identified multiple drill ready
targets at the Enonkoski nickel-copper-cobalt project in East
Finland. Bluejay's Hammaslahti copper-zinc-gold-silver project
hosts high-grade VMS mineralisation and extensions of historical
ore lodes have been proven. The drill ready Outokumpu
copper-nickel-cobalt-zinc-gold-silver project is located in a
prolific geological belt that hosts several high-grade former
mines. In August 2023, Bluejay successfully divested its Black
Schist Projects in Finland to Metals One plc in a transaction worth
GBP4.125 million (Bluejay currently owns c. 29% of the issued
ordinary share capital of AIM listed Metals One plc).
[1] non-verified historical assay results reported prior to
Bluejay's interest in the property (source: Olshefsky et al., 1995
, company report by Falconbridge; GEUS report number 21410). The
assay relates to Falconbridge diamond drillhole "FP94-4-5", which
drilled through both the hanging and footwall of the Qullissat
intrusion. A native iron cumulate was intersected in the basal part
of the intrusion from 177.4 to 190.5m. The native iron droplets
were 0.5 to 2 mm in diameter and had a modal composition varying
from trace amounts up to 5% over the 13m intersection. The core
from the iron cumulate zone was split and 12 samples were collected
for geochemical analysis (NS03214 to NS03226). Three samples
(NS03214, 03217 and 03226) were processed by magnetic separation
and the non-magnetic and magnetic fractions were analysed by fire
assay. All samples returned anomalous gold values with the highest
concentrations up to 4.83 g/t gold associated with the magnetic
fraction. A second processing of sample NS03226 returned higher
grades of 14.8 g/t gold. Samples NS03226 and NS03214 were then
reprocessed using a finer grind, resulting in increased gold values
from the finer magnetic fraction up to 38.3 g/t gold. The erratic
gold values returned from the magnetic concentrates and the whole
core samples suggest that the occurrence of gold in the Qullissat
intrusion is sporadic.
[2] Note: the sub-horizontal magmatic body at Qullissat
comprises of a native-iron bearing magnesian basaltic andesite
which is considered equivalent to the Asuk Member of the Vaigat
Formation. The body is widely described in the literature as a
high-level sill (e.g., Olshefsky and Jerome, 1994 ; Pedersen et
al., 2017), however recent investigations of historical drill cores
have suggested the body could alternatively be an extrusive lava
flow (e.g., Dr Asger Ken Pedersen, Personal Communication as
referenced in Jackisch et al., 2022 ) or invasive lava flow, rather
than an intrusive sill. Relogging of historical drill cores is
planned to help resolve this.
[3] "Chonolith": A small (typically <1 km thickness)
irregular, tube-shaped intrusion of mafic-ultramafic composition
much longer than it is thick and longer than it is wide (e.g.,
typical aspect ratios of chonoliths in the Norilsk region are
roughly 100:10:1) that sharply and on a large-scale crosscut their
host country rocks. Many chonoliths display evidence that they were
emplaced at least in part by thermomechanical erosion of country
rocks, and almost all contain a high proportion of cumulate rocks.
Most of the world's major deposits of nickel and copper were formed
as accumulations of magmatic sulphide liquid within chonoliths,
that are thought to have developed as conduits within magmatic
plumbing systems. The term is also used more loosely in the
scientific literature to denote any small discordant mafic
intrusion that is not clearly either a sill or a dyke (definition
adapted from: Barnes et al., 2020 and Barnes and Mungall, 2018
).
[4] non-verified historical assay results reported prior to
Bluejay's interest in the property (data sources provided as
hyperlinks within the text).
[5] 'Aqua Regia Digestion' is an acid mixture of nitric and
hydrochloric acids in a 1:3 ratio providing a partial
extraction.
[6] 'Four Acid Digestion' is an acid mixture of nitric,
perchloric, and hydrofluoric acids with a final dissolution stage
using hydrochloric acid. This digestion breaks down most silicate
and oxide minerals allowing for the "near-total" recovery of most
minerals.
