Results of Drilling at Black Schist
Ni-Cu-Co-Zn Project, Finland
Significant intersections of mineralised
black schists identified at R1 Hook target
Metals
One (AIM: MET1), which is advancing battery metal
projects at brownfield sites in Finland and Norway, is pleased to
report the laboratory results from its eight diamond drillholes at
the R1 Hook target, located within the Rauta 9-11 licence area at
the Black Schist Project in Finland.
Significant intersections of mineralised black
schists were identified in all eight drillholes, whilst drilling
has also demonstrated geological continuity with the Company's
existing Resource at R1 which could support future resource
expansion.
Highlights
·
Hole RAU0002 intercepted 14.7m of mineralised black schists
from 50m (0.18% Ni, 0.01% Cu, 0.01% Co, 0.57% Zn)
·
Hole RAU0003 intercepted 11m of mineralised black schists
from 199.5m (0.22% Ni, 0.01% Cu, 0.01% Co, 0.55% Zn)
·
Established geological continuity between R1 Hook and the
existing R1 Resource, supporting future resource
expansion
·
Confirmed synformal structure, indicating significant
potential to the east and prompting the Company to extend the
current permit area in that direction
R1 Hook
Drilling Programme
The objectives of the programme were to confirm
the structure and its potential to host Talvivaara-type Ni-Cu-Co-Zn
mineralisation. Talvivaara is one of Europe's largest and
lowest-cost producers of critical battery metals, located 63km to
the north of this target.
A total of 1,551.2m were drilled along what,
according to ground and airborne geophysical surveys, appeared to
be a fold structure to the east of the Company's R1
Resource.
All drillholes intercepted mineralised black
schists, with the best thickness and grades intersected on the
eastern limb of the main R1 Hook fold. This observation, together
with confirmation of the synformal nature of the limb, dipping
steeply to the south, suggests significant potential for further
mineralisation to the east, beyond the boundary of the Company's
existing permit. The Company has lodged a reservation to secure
this area, known as Kirkkosuo, with the intention of confirming the
extension of the structure and mineralisation with a limited
diamond drill programme to follow in due course.
Metals One continues to update its
prospectivity model with the valuable geophysical and petrophysical
insights into the nature of mineralised black schists gathered
during this programme.
Jonathan Owen,
Chief Executive Officer of Metals One, commented:
"Leveraging
new and historical insights and data, the Metals One team is
pleased to identify this economically important Talvivaara style of
mineralisation. The resulting prospectivity model developed by the
team significantly reduces discovery risk as we continue to target
high-quality critical battery metal resources across the Kainuu
Schist Belt.
I would like
to thank our exploration team for the perfect execution of the
drilling programme, which we delivered on schedule, on budget, and
with the close support of the local Rautavaara
community.
I look
forward with excitement to the further development of our R1
Resource, and its potential extension to the east through the R1
Hook and beyond."

Commentary
|
Sampling techniques
|
·
Nature and
quality of sampling (e.g. cut channels, random chips, or specific
specialised industry standard measurement tools appropriate to the
minerals under investigation, such as down hole gamma sondes, or
handheld XRF instruments, etc). These examples should not be taken
as limiting the broad meaning of sampling.
·
Include
reference to measures taken to ensure sample representation and the
appropriate calibration of any measurement tools or systems
used.
·
Aspects of the
determination of mineralisation that are Material to the Public
Report.
·
In cases where
'industry standard' work has been done this would be relatively
simple (eg 'reverse circulation drilling was used to obtain 1 m
samples from which 3 kg was pulverised to produce a 30 g charge for
fire assay'). In other cases, more explanation may be required,
such as where there is coarse gold that has inherent sampling
problems. Unusual commodities or mineralisation types (eg submarine
nodules) may warrant disclosure of detailed
information.
|
·
A total of 8 diamond drillholes for 1551,2 m were
completed.
·
Drill core was placed in order in wooden trays,
with depth marker blocks at the drilling location. Trays were
transported to Metals One Finland's core shed in Outokumpu where
they were stored inside the secure shed for geological and
geotechnical logging, mark-up for sampling and digital
photography.
·
All samples retrieved are from diamond drill cores
that have been cut longitudinally in half according to lithological
and mineralisation intervals and prepared for assaying. The samples
are predominantly 1 m in length.
·
All samples were submitted to ALS-Geochemistry Oy
in Outokumpu, Finland for assaying.
·
A prepared sample (0.25 g) was digested with
perchloric, nitric, hydrofluoric, and hydrochloric acids. The
residue was leached with dilute hydrochloric acid and diluted to
volume. The resulting solution was analysed by a combination of
inductively coupled plasma-atomic emission spectrometry (ICP-AES)
and inductively coupled plasma-mass spectrometry with results
corrected for spectral or isotopic interferences.
·
Also assaying for gold was made by using Fire
Assay Fusion (FA-FUSPG1 & FA-FUSPG2) and Inductively Couple
Plasma - Atomic Emission Spectrometry (ICP-AES)
|
Drilling techniques
|
·
Drill type (e.g.
core, reverse circulation, open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc) and details (e.g. core diameter, triple
or standard tube, depth of diamond tails, face-sampling bit or
other type, whether core is oriented and if so, by what method,
etc).
|
·
All drilling was made by diamond drilling, angled
holes were planned and drilled. All the cores were drilled as WL76
(core 57.5 mm diameter).
·
Orientation markings on every core run.
|
Drill sample recovery
|
·
Method of
recording and assessing core and chip sample recoveries and results
assessed.
·
Measures taken
to maximise sample recovery and ensure representative nature of the
samples.
·
Whether a
relationship exists between sample recovery and grade and whether
sample bias may have occurred due to preferential loss/gain of
fine/coarse material.
|
·
Core recovery was calculated on a per drill-run
basis (maximum 3 m). Core recovery averaged 95%, ranging from 0% to
100%. Only 96 intervals did not have a recovery of 100%,
|
Logging
|
·
Whether core and
chip samples have been geologically and geotechnically logged to a
level of detail to support appropriate Mineral Resource estimation,
mining studies and metallurgical studies.
·
Whether logging
is qualitative or quantitative in nature. Core (or costean,
channel, etc) photography.
·
The total length
and percentage of the relevant intersections
logged.
|
·
Drill core was logged in detail for lithology,
alteration, mineralisation, geological structure, by geologists,
utilising standardised logging codes and data sheets as supervised
by the senior geologist.
·
Rock Quality Designation (RQD) logs were produced
for all core drilling for geotechnical purposes. Fracture intensity
and fragmentation proportion analysis was also gathered for
geotechnical information.
·
Logging was both quantitative and qualitative in
nature. All core was photographed in the core boxes to show the
core box number, core run markers and a scale.
|
Sub-sampling techniques and sample
preparation
|
·
If core, whether
cut or sawn and whether quarter, half or all core
taken.
·
If non-core,
whether riffled, tube sampled, rotary split, etc and whether
sampled wet or dry.
·
For all sample
types, the nature, quality and appropriateness of the sample
preparation technique.
·
Quality control
procedures adopted for all sub-sampling stages to maximise
representation of samples.
·
Measures taken
to ensure that the sampling is representative of the in-situ
material collected, including for instance results for field
duplicate/second-half sampling.
·
Whether sample
sizes are appropriate to the grain size of the material being
sampled.
|
·
Full core was split longitudinally using a rock
diamond saw to create half-core samples that were taken at
typically 1 m intervals or to rock contacts if present in the core
run for both mineralization and wall rock. The drill core was
rotated prior to cutting to maximise structure to core axis of the
cut core.
·
Half core was taken for sampling for assaying, and
one half remains in the core box as reference material.
·
Core samples were prepared according to industry
best practice, with initial geological control of the half core,
followed by crushing and grinding at the laboratory sample
preparation facility that is routinely managed for contamination
and cleanliness control. Sampling practice is considered as
appropriate for Mineral Resource Estimation.
·
Blanks, duplicates and certified reference
materials were inserted into the sample stream at a rate of 1 blank
and standard for every 20 samples.
·
Sample sizes are considered appropriate to the
grain size of the rocks and style of mineralization being
sampled.
|
Quality of assay data and laboratory tests
|
·
The nature,
quality and appropriateness of the assaying and laboratory
procedures used and whether the technique is considered partial or
total.
·
For geophysical
tools, spectrometers, handheld XRF instruments, etc, the parameters
used in determining the analysis including instrument make and
model, reading times, calibrations factors applied and their
derivation, etc.
·
Nature of
quality control procedures adopted (e.g. standards, blanks,
duplicates, external laboratory checks) and whether acceptable
levels of accuracy (i.e. lack of bias) and precision have been
established.
|
·
Gold assaying was conducted by
ALS-laboratories.
·
Assaying for Ni, Cu, Co and Zn was conducted by
ALS-laboratories.
·
Each sample was geochemically analysed for the
following suite of elements: 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, Zr.
·
A variety of AMIS CRMs have been used for quality
control purposes for all assaying methods. In addition, blanks and
pulp duplicates have been assayed to assess the accuracy,
repeatability, consistency of analytical methods and machines and
for sample contamination.
|
Verification of sampling and assaying
|
·
The verification
of significant intersections by either independent or alternative
company personnel.
·
The use of
twinned holes.
·
Documentation of
primary data, data entry procedures, data verification, data
storage (physical and electronic) protocols.
·
Discuss any
adjustment to assay data.
|
·
Significant intersections were verified by a
number of company personnel within the management structure of the
Exploration team. Intersections were defined by the exploration
geologists, and subsequently verified by the Exploration
Manager.
·
Metals One Finland uses Leapfrog GEO and Imago
software for data entry, verification, quality control, logging
data and core photography. The data is stored on the cloud and is
also saved and stored in MS Excel and MS Access software on Metals
One Finland´s internal data drives as a backup and for use in
geological modelling software.
·

verification and checking procedures are in place. The format of
the data is appropriate for use in resource estimation
|
Location of data points
|
·
Accuracy and
quality of surveys used to locate drill holes (collar and down-hole
surveys), trenches, mine workings and other locations used in
Mineral Resource estimation.
·
Specification of
the grid system used.
·
Quality and
adequacy of topographic control.
|
·
Drillhole collars were laid out using handheld
global positioning system (GPS). The rigs were aligned with survey
control, or by compass.
·
A gyroscopic survey instrument (Devicore) was
utilised by Northdrill Oy during the course of the Rautavaara R1
Hook surface drill programs.

·
Whether the data
spacing, and distribution is sufficient to establish the degree of
geological and grade continuity appropriate for the Mineral
Resource and Ore Reserve estimation procedure(s) and
classifications applied.
·
Whether sample
compositing has been applied.
|
·
Average drillhole density at the Rautavaara R1
Hook target is variably spaced dependent on the exploration target
characteristics.
·
No Mineral Resource or Ore Reserve estimations are
being reported.
|
Orientation of data in relation to geological
structure
|
·
Whether the
orientation of sampling achieves unbiased sampling of possible
structures and the extent to which this is known, considering the
deposit type.
·
If the
relationship between the drilling orientation and the orientation
of key mineralised structures is considered to have introduced a
sampling bias, this should be assessed and reported if
material.
|
·
Diamond drillholes were oriented, wherever
possible, perpendicular to the mineralized structures.
|
Sample security
|
·
The measures
taken to ensure sample security.
|
·
The drilling site is supervised by a Supervising
Geologist, the drill core is placed into wooden core boxes that are
sized specifically for the drill core diameter. A wooden lid is
fixed to the box to ensure no spillage. Core box number, drill hole
number and from/to meters are written on both the box and the lid.
The core is then transported to the core storage area and logging
facility, where it is received and logged into a data sheet. Core
logging, and sampling takes place at the secure core management
area. The core samples are marked with labels both in and on the
core boxes, and data recorded on a sample sheet. The samples are
transferred to the laboratory where they are registered as
received, for laboratory sample preparation works and assaying.
Hence, a chain of custody procedure has been followed from core
collection to assaying and storage of pulp/remnant sample
material.
·
All samples received at the core facility are
logged and registered on a certificate sheet. The certificate sheet
is signed by core facility supervisor (responsible person). All
core is photographed, geotechnical logging, geological logging,
sample interval determination, bulk density testing, and sample
preparation.
·
For external assaying, Metals One Finland Oy
utilises ALS-Geochemistry Oy in Outokumpu, Finland.

Rauta 9-11 (ML2012:0169) are a extension to
existing exploration permit and the applications have been lodged
under Metals One Finland Oy.
·
Under Finnish legislation and in relation an
Exploration Permit, as stipulated in the permit's conditions, the
permit holder has the right to conduct geological surveying and
other exploration works necessary for establishing the location,
shape, orientation and exploitability of a mineral deposit. The
extent of measures depends on the permit stipulations imposed by
the Mining Authority and the measures may be undertaken without the
landowner's permit, i.e. the exploration permit replaces landowner
permissions. The permit stipulations may allow invasive drilling or
test mining. The initial term is a maximum of four years,
extensions applicable three years at a time to the cap of 15 years
(4+3+3+3+2). "Claims" under the 1965 Mining Act correspond to
exploration permits under the 2011 Mining Act which was renewed in
2023 (505/2023). The main difference between claims and exploration
permits is that claims are initially valid for five years instead
of four. Thus, considering transitional provisions in the 2011
Mining Act, claims are valid for 5+3+3+3+1 years. An exploration
permit application in itself does not entitle the applicant to
conduct exploration activities. However, exploration can be
conducted with a landowner consent already.

Exploration done by other parties
|
·
Acknowledgment
and appraisal of exploration by other parties.
|
·
Two phases of exploratory drilling have been
completed at Rautavaara. The GTK completed five diamond drillholes
in 1979 totalling 879 m, and FinnAust Mining Oy has subsequently
completed 43 drillholes totalling a further 5,425 m.
·
Between 2006 and 2008, Magnus Minerals (Magnus), a
privately held Finnish exploration company, carried out a review
and interpretation of publicly available airborne geophysics,
regional geology and historical exploration data, in the Kainuu
Schist Belt and Outokumpu-Savonranta Belt, central and southern
Finland.
·
During 2009 and 2010, close-spaced ground magnetic
data was acquired, and several phases of surface diamond drilling
were undertaken with an Onram 1000/three rubber-tracked rig
operated by SMOY. Six diamond holes were drilled between September
2009 and January 2010.
|
Geology
|
·
Deposit type,
geological setting and style of mineralisation.
|
·
The Kainuu Schist Belt is represented by remnants
of rocks deposited into an oceanic volcano-sedimentary rift basin
which developed from Early to Mid-Proterozoic the Archaean crustal
Karelian Craton Boundary. It is mostly represented by basal
siliceous rocks (interpreted as quartzites) and minor mafic
volcanics, metalliferous black schists, wackes with intercalated
calcsilicate rocks, ophiolitic ultramafic rocks, and minor
serpentinite.
·
The Rautavaara Project is hosted within remnants
of the southern Kainuu Schist Belt (Early Proterozoic) which
consists mainly of quartzites, mica schists and black schists
resting paraconformably on the Archean basement gneiss complex. The
black schists are variably recrystallized carbon and sulphide-rich
black metasediments.
·
The nickel-zinc-copper-cobalt mineralisation is
stratabound, hosted within the high-grade metamorphosed and
intensely folded black schist. The main mineral assemblage in the
black schist is quartz, mica, graphite, and sulphides.
·
The origin of the black schist mineralisation is
postulated to be a result of metal precipitation under a specific
set of local conditions unique to that margin at the time of
deposition. It is generally accepted that the black shales
represent organic carbon-rich muds accumulated under anoxic and
sulphidic conditions, and that the metals were derived by direct
precipitation from the seawater column, settling out to the ocean
floor onto the water-sediment interface. It seems that only the
very uppermost part of the basinal water column was
oxygenated.
·
Pyrite and pyrrhotite are the dominant sulphide
minerals within the black schist deposits at Rautavaara, similar to
the Talvivaara deposit. The sulphidic nickel-zinc-copper-cobalt
deposits are hosted by highly sulphidic-graphitic muds and
turbiditic wackes; which have undergone a high degree (amphibolite
facies) of metamorphism.

Drill hole Information
|
·
A summary of all
information material to the understanding of the exploration
results including a tabulation of the following information for all
Material drill holes:
o easting and northing of the
drill hole collar
o elevation or RL (Reduced
Level - elevation above sea level in metres) of the drill hole
collar
o dip and azimuth of the
hole.
o down hole length and
interception depth
o hole
length.
·
If the exclusion
of this information is justified on the basis that the information
is not Material and this exclusion does not detract from the
understanding of the report, the Competent Person should clearly
explain why this is the case.
|
·
The first phase of holes drilled were all angled
between 45 and 60 deg.
·
All holes drilled, their collar co-ordinates
azimuth, dip and final depths are tabulated below.
|
Data aggregation methods
|
·
In reporting
Exploration Results, weighting averaging techniques, maximum and/or
minimum grade truncations (e.g. cutting of high grades) and cut-off
grades are usually Material and should be stated.
·
Where aggregate
intercepts incorporate short lengths of high-grade results and
longer lengths of low-grade results, the procedure used for such
aggregation should be stated and some typical examples of such
aggregations should be shown in detail.
·
The assumptions
used for any reporting of metal equivalent values should be clearly
stated.
|
·
Significant intercepts are reported using a cut
off of 0.10% nickel.
|
Relationship between mineralisation widths and intercept
lengths
|
·
These
relationships are particularly important in the reporting of
Exploration Results.
·
If the geometry
of the mineralisation with respect to the drill hole angle is
known, its nature should be reported.
·
If it is not
known and only the down hole lengths are reported, there should be
a clear statement to this effect (e.g. 'down hole length, true
width not known').
|
·
All intercepts are reported as down-hole
lengths
|
Diagrams
|
·
Appropriate maps
and sections (with scales) and tabulations of intercepts should be
included for any significant discovery being reported These should
include, but not be limited to a plan view of drill hole collar
locations and appropriate sectional views.
|
·
Maps and sections are provided in the
report
|
Other substantive exploration data
|
·
Other
exploration data, if meaningful and material, should be reported
including (but not limited to): geological observations;
geophysical survey results; geochemical survey results; bulk
samples - size and method of treatment; metallurgical test results;
bulk density, groundwater, geotechnical and rock characteristics;
potential deleterious or contaminating
substances.
