·   Nature and quality of sampling (eg 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 representivity 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 2 historical diamond drillholes (M343281R325 and M343281R326) (236,8m) at Paltamo P1 were re-assayed.

·   When drilled by GTK, the drill core was placed in order in wooden trays, with depth marker blocks at the drilling location.

·   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 1-2 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.

·   Full core was split longitudinally using a rock diamond saw to create half-core samples that were taken at typically 1-2 m intervals or to rock contacts if present in the core run for both mineralisation 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.

·   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.

·   Paltamo P1 (ML2024:0050) is an application for an exploration permit and the application has been lodged under Metals One Exploration Oy a subsidiary of Metals One PLC.

·   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, taking into account 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.

·   Acknowledgment and appraisal of exploration by other parties.

·   The GTK carried out detailed work in the Paltamo area from 1972 to 1982. Work included 6 drillholes for a total of 982.65 m, base of till geochemical sampling, ground magnetics, slingram EM and gravimetric surveys, and airborne magnetics and EM flown on 200 m east-west line spacing in 1982. Regional bedrock mapping by GTK in 1990-1999 resulted in publication of a 1:100,000 geological map in 2004.

·   FinnAust drilled 44 drillholes from 2010 to 2012 in the Paltamo target area for a total of 9251.05 m drilling. Drilling intersected copper-cobalt-zinc-nickel mineralised black shales at the Paltamo target area.

·   No further exploration activity has been undertaken post-2012, and no ground geophysical surveys have been completed post-2012. No airborne EM surveys have been flown over the property post-1982.

·   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 Paltamo Project area is hosted within remnants of the northern part of the 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 recrystallised carbon and sulphide-rich black metasediments. The rock units of the Paltamo P1 area is striking in north - south direction 1200m and having a gentle dip of 5 - 20 degrees to west.

·   The nickel-zinc-copper-cobalt mineralisation is strata bound, 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 Paltamo, 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.

·   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 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.

·   Re-assayed historical drillholes tabulated below:

·   In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg 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.

·   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 (eg 'down hole length, true width not known').

·   All intercepts are reported as down-hole lengths

·   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

·   Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.

·   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.
