Mawson Finland Limited Reports First Results for 2025 Winter Drilling Program Significant Step-out Extensions in Rajapalot and New Downhole-EM Survey Results

Mawson Finland Limited("Mawson" or the "Company") (TSXV:MFL) is pleased to announce drilling results from the first 6 drillholes from the 2025 drilling season at the Company's wholly-owned Rajapalot gold-cobalt project in Finland (see Table 1, Table 2, Table 3, and Figure 1 in Schedule "A" hereto).

Highlights:

• 120 metre step-out discovery from Drillhole PAL0373 in South Palokas confirms the effectiveness of the project EM survey
• Further significant gold-bearing intercepts drilled in down-dip extensions at Palokas zone in PAL0380
• Confirmation of mineralised ‘Raja-footwall' EM conductor in drillhole PAL0378
• Additional downhole EM (DHEM) surveys confirm the presence of significant conductors at depth in potential ‘down-dip' Raja position

Ms. Noora Ahola, Mawson Finland CEO, states:"We are very pleased to present the first of our results from the 2025 drilling season at Rajapalot. Most significantly, we have demonstrated the larger potential of both the South Palokas and Palokas mineralised zones, intercepting gold-bearing mineralisation in a large 120 metre step-out down-dip of our deepest intercept at South Palokas which targeted a deep downhole-EM conductor discovered in our recent 2024 geophysics program. Significant intercepts have also been drilled in the deeper portions of the Palokas zone, while additional mineralisation is also confirmed from Raja resource extension drillholes. Additional downhole-EM geophysical surveys conducted in January 2025 have also indicated the potential of further mineralization of the projected down-dip extension of the Raja zone in which target-test drilling will be immediately undertaken. These initial successes from our 2025 drilling season demonstrate open mineralisation to depth in several of our important mineralised zones, and bodes well for our ongoing resource expansion objectives. We look forward to bringing further drilling results in the very near future."

Detailed Results

Winter Drilling

Four diamond drilling rigs are actively drilling at the Rajapalot project. Ten diamond drillholes have been completed to date, for a total of 4,424 metres at time of writing. Primary aims for this season's drilling program are to extend the limits of the currently defined envelope of the Rajapalot inferred mineral resource, while secondary aims focus on target-test drilling of geochemical and geophysical targets developed during the summer and autumn field exploration season in order to advance the ‘exploration pipeline' and define new zones of gold-cobalt mineralization. To date, gold-assay results (cobalt values to be announced) have been received for the first 6 of the 10 completed holes and presented in Table 1, 2 and 3, and Figure 1.

South Palokas: To date, a single 1,004 metre drillhole PAL0373 - the deepest ever drilled at Rajapalot - has been completed at South Palokas, where it successfully penetrated the modelled deep, southern conductive anomaly (South Palokas deep conductor "A"), returning a significant intercept of 5 m @ 0.58 g/t Au from 785.65 metres downhole (see Figure 2). This intercept demonstrates the steeply-dipping, depth-continuation of South Palokas, representing an approximate 120m step-out in the plane of mineralisation. Closest significant intersections are PAL0303 with 30.8 metres @ 5.1 g/t Au at 120m distance and distance of 150m PAL0361 with 6m @ 2.24 g/t Au and 5.3m 2.73 g/t Au (Reported previously). Further drilling will be carried out in order to define geometry and test for high-grade mineralisation in the core-portions of the modelled conductive zone (refer to Figure 2).

Palokas: To date, 3 drillholes have been completed at Palokas zone of gold-cobalt mineralization, of which PAL0380 has returned a dispersed mineralised zone consisting of 5 separated intercepts recording a best of 6 m @ 1.03 g/t gold, and 7 m @ 0.57 g/t gold (refer to Table 2). Drillhole PAL0377 did not record any significant intercept, and drillhole PAL0382 awaits logging, sampling and assay.

Raja: To date, 4 drillholes have been completed at Raja, with significant intercepts recorded in holes PAL0374 (0.5 m @ 0.85 g/t gold), PAL0376 (6.2 m @ 2.42 g/t gold) and PAL0378 (best intercept of 8 m @ 1.22 g/t gold; refer to Table 2 and Figure 3). Drillhole PAL0381 awaits logging, sampling and assay. Importantly, drillhole PAL0378 intercepted the modelled downhole-EM conductor situated in the footwall-zone below the main Raja lens of mineralisation, confirming gold-mineralisation in this conductive anomaly, returning a 2.05 metre thick gold-bearing interval of 1.29 g/t gold (refer to Figure 3).

Geophysics

In January 2025, a series of downhole-EM surveys were carried out in the lower portions of the Raja zone in order to search for any conductive bodies in and around the historical deeper drilling. Downhole probes were sent down drillholes PAL0180, PAL0230 and PAL169, where each detected a series of off-hole conductors. Most notably, a conductive anomaly was detected below and to the immediate south of drillhole PAL0180, with the modelled plate measuring 150 x 75 metres, dipping shallowly to the north-west, with the centre of the modelled plate located approximately 640 metres below surface (refer to Figure 3; Raja deep conductor "B"). Similarly, off-hole and overlapping conductive anomalies were recorded from drillholes PAL0230 and PAL0169, with the modelled overlapping plates measuring a combined 200 x 50 metres in area, dipping shallowly to the north-west, with centres of the modelled plates located between 508 and 520 metres below surface (refer to Figure 3; Raja deep conductor "A"). Geophysical modelling and interpretation of these conductive anomalies is ongoing and more refined findings will be presented in future news releases.

Technical Background, Data Verification and Quality Assurance and Quality Control

Four diamond drill rigs from MK Core Drilling Oy, Comadev Oy and Arctic Drilling Company Oy, all with water recirculation and drill cuttings collection systems, were used in this drill program. Core diameter is NQ2 (50.7 mm). Core recoveries are excellent and average close to 100% in fresh rock. After photographing and logging in Mawson's Rovaniemi facilities, core intervals of between 0.4 to 2 metres are taken, then half-sawn by independent contractors the Geological Survey of Finland (GTK) in Rovaniemi, Palsatech Oy in Kemi and Geopool Oy in Sodankylä. The remaining half core is retained for verification and reference purposes. Analytical samples are transported by commercial transport from site to the independent contractor CRS Minlab Oy ("CRS") facility in Kempele, Finland. Samples were prepared and analyzed for gold using the PAL1000 technique which involves grinding the sample in steel pots with abrasive media in the presence of cyanide, followed by measuring the gold in solution with flame AAS equipment. Samples for multi-element analysis (including cobalt) are pulped at CRS, then transported by air to MSALABS in Vancouver, Canada and analyzed using four acid digest ICP-MS methods. All the foregoing laboratories are independent of the Company. The quality assurance and quality control program of Mawson consists of the systematic insertion of certified standards of known gold content, duplicate samples by quartering the core, and blanks placed within sample runs in interpreted mineralized rock. In addition, CRS inserts blanks and standards into the analytical process. In addition to the sample preparation and security measures described above, data verification procedures are well integrated into the Company's quality assurance and quality control program. Routine ongoing checking of all data is undertaken prior to being uploaded to the database. This will be followed by independent data verification audits at exploration milestones throughout the Rajapalot project's development. Dr. Fromhold (see "Qualified Person" below) has also reviewed the qualifications and analytical procedures of the above-mentioned laboratories, photographs of drill cores, and the PEA in connection with verifying the exploration information presented herein.

All maps have been created within the KKJ3/Finland Uniform Coordinate System (EPSG:2393). Tables 1-3 in Schedule "A" hereto provide collar and assay data. Due to the typically low angles of drill intercepts, the true thickness of the mineralized intervals are interpreted to be approximately 80-90% of the drilled thickness. Table 3 gives detailed individual assay data of all intervals reported in this press release. Intersections are reported with a lower cut of 0.1 g/t Au over sampled intervals, with composite data (Table 2 in Schedule "A" hereto) containing no more than 2 metres of consecutively sampled waste-rock (i.e., 2 metres @ <0.05 g/t Au). No upper-cut was applied.

Geophysical Survey Parameters

The downhole EM (DHEM) survey was conducted by Finnish geophysics provider Geovisor Oy from Rovaniemi, using a Zonge ZT-30 transmitter system. The acquisition was measured using the EMIT Smartem24 receiver system with EMIT DHEM Digiatlantis probe that measures the decaying magnetic field with three orthogonal Fluxgate magnetometer sensors producing along hole (A-component), and two perpendicular components (namely U and V- components). For each loop configuration, the base frequency was tested, and the base frequency was altered from 0.25 Hz to 1 Hz. The EM response was stacked over 32,128 EM pulses depending on the base frequency and the observed signal strength. The used time windows scheme was SMARTem standard containing 39 to 43 time channels depending on the base frequency. All the holes were measured in one piece from the collar with surveys having 10 metre reading intervals. The modelling was done using Maxwell software, using plate models. All maps have been created within the KKJ3/Finland Uniform Coordinate System (EPSG:2393).

Deposit Model

At Rajapalot, mineralization is regarded as orogenic in nature. All examples of gold-cobalt mineralisation are consistently located within highly-sheared and foliated wall-rocks adjacent to strongly hydrothermally altered, northwest to north dipping shear-zones. Mineralisation is typically encountered as disseminated to semi-massive sulfide lenses (predominantly pyrrhotite and lesser pyrite  cobaltite), hosted within strongly deformed and altered, mafic volcanic and volcaniclasitic stratigraphy of the upper portions of the Paleoproterozoic-aged Kivalo Group of the Peräpohja Greenstone Belt. Prospects with high-grade gold and cobalt mineralisation at Rajapalot occur across a 3 km (east-west) by 2 km (north-south) area within the larger Rajapalot project area measuring 4 km by 4 km with multiple mineralized boulders, base-of-till (BOT). Gold-Cobalt mineralization at Rajapalot has been drilled to approximately 470 metres below surface at both South Palokas and Raja prospects, and mineralisation remains open at depth across the entire project.

Rajapalot Mineral Resource

An Inferred Mineral Resource ("MRE") has been calculated for the Rajapalot project (effective date August 26, 2021), and is based on an ‘underground only' mining scenario containing 9.8 million tonnes @ 2.8 g/t gold ("Au") and 441 ppm Co, equating to 867 thousand ounces ("koz") gold and 4,311 tonnes of cobalt.

Rajapalot Inferred Mineral Resource Effective August 26, 2021

• ^{The independent geologist and Qualified Person as defined in NI 43-101 for the mineral resource estimates is Mr. Ove Klavér (EurGeol). The effective date of the MRE remains unchanged to the Previous MRE (August 26, 2021, available on SEDAR as filed by the previous owner, Mawson), and will be restated in the PEA technical report when it is filed.}
• ^{The mineral estimate is reported for a potential underground only scenario. Inferred resources were reported at a cut-off grade of 1.1 g/t (AuEq1 Au g/t + Co ppm /1005) with a depth of 20 meters below the base of solid rock regarded as the near-surface limit of potential mining.}
• ^{Wireframe models were generated using gold and cobalt shells separately. Forty-eight separate gold and cobalt wireframes were constructed in Leapfrog Geo and grade distributions independently estimated using Ordinary Kriging in Leapfrog Edge. A gold top cut of 50 g/t Au was used for the gold domains. A cobalt top cut was not applied.}
• ^{A parent block size of 12 m x 12 m x 4 m (>20% of the drillhole spacing) was determined as suitable. Sub-blocking down to 4 m x 4 m x 0.5 m was used for geologic control on volumes, thinner and moderately dipping wireframes.}
• ^{Rounding of grades and tonnes may introduce apparent errors in averages and contained metals.}
• ^{Drilling results to 20 June 2021.}
• ^{Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.}
