Ms. Noora Ahola, Mawson Finland CEO, states:"We are very excited to report the results of our recent geophysics surveys at Rajapalot. We have identified several exciting targets in downhole EM surveys that suggest the gold-cobalt mineralization at Rajapalot continues with depth at Palokas and South Palokas, while further anomalies are also present in un-drilled areas close-by. We plan to conduct further EM geophysical studies at Rajapalot in the coming weeks in our lead-up to the 2025 winter drilling campaign, in addition to an approximate 600-hectare sub-audio magnetic "SAM" ground-survey presently being carried out over our high-grade Rompas gold project located 6 kilometres east of Rajapalot. We look forward to presenting the results of these additional surveys prior to the initiation of our winter drilling campaign planned to begin in January 2025."
Downhole EM Results
Electromagnetic techniques were first used in 2013 by Mawson at Rajapalot with a helicopter-borne VTEMplus survey indicating the conductive nature of areas subsequently discovered to be the Palokas, South Palokas, The Hut, Terry's Hammer, Rumajärvi, Raja and Joki zones of gold-cobalt mineralization. Due to the close association of gold-cobalt mineralization with pyrrhotite accumulations at the known mineralized occurrences at the Rajapalot project, detection of these sulfide-bearing mineral-systems with EM geophysical methods is achievable due to their associative, highly-reactive EM properties.
In this downhole EM campaign, five EM-loops were set-out in order to measure conductivity responses in the vicinity of 8 selected drillholes to explore for further nearby gold-cobalt mineralized rock-bodies at Rajapalot (refer to map in Figure 1). Five of 8 drillholes, corresponding to 3-EM loops (loops 1-3), were located around the Palokas and South Palokas zones of gold-cobalt mineralization, while 1 drillhole (loop 4) was located 400 metres north-east of Palokas, and 2 drillholes (loop 5) located on the northern margin of the Raja zone (refer to Figure 1 for drillhole, and EM-loop locations/survey layout).
At South Palokas, 2 strong EM conductors were located ‘off-hole' to both the north and south of drillhole PAL0367 (loop 3) at the presently defined base of gold-cobalt mineralization. South Palokas conductive body "A" is found to the south of drillhole PAL0367, with the top of the conductor modelled at around -340mRL and continues for some 200 metres in the down-dip direction, while conductive body "B" is located to the north of drillhole PAL0367, with its top modelled at -370mRL and continues for a further 110 metres in the down-dip direction (refer Table 1, and to 3-D projections in Figure 2 and Figure 3). These results strongly suggest that further gold-cobalt mineralization may be present at depth at South Palokas.
At Palokas, a strong EM-conductive body is interpreted on the lower, northern margin of the mineralized zone, extending down-dip from PAL0200 (loop 3), with the top of this conductor modelled at -129mRL, continuing a further 135 metres in the down-dip direction. This modelled conductor initially appears coincident with the lower portions of the deeper areas of the Palokas mineralized zone however, it is interpreted to be separated from the main Palokas mineralized zone. The anomaly isn't readily explained by simply enlarging the presently known geometry of the Palokas mineralized system down-dip with a northerly plunge and as such, these results suggest an additional lens of gold-cobalt mineralization may exist beyond the known limits of mineralization in the deeper areas of the Palokas zone (refer Table 1, and to 3-D projections in Figure 2 and Figure 3).
Two further loops were set-out in the Palokas and South Palokas area in order to search for conductive rocks in between Palokas and South Palokas zones of mineralization (drillhole PAL0352; loop 1), and to search the footwall zone to Palokas in light of the recent discovery of "New Lens" in the footwall area of South Palokas (drillholes PAL0072 and PAL0362; loop 2; refer to Figure 1). No conductive anomalies were observed in these areas beyond that of the signals detected from the known mineralized conductive bodies of both Palokas and South Palokas.
North-east of Palokas, approximately 400 metres along-strike, a further drillhole, PAL0073 (loop 4), was used to measure for the presence of deep conductive anomalies in the vicinity of this drillhole. A strongly conductive, 150m by 150m sized EM anomaly was modelled ‘off-hole' to the north of PAL0073, approximately 220 metres below surface at the -50mRL (refer to Table 1, Figure 1, and 3D EM-plate model in Figure 4). These data suggest the presence of a potentially mineralized rock-system located approximately 450 to 600 metres along-strike, to the north-east of the Palokas zone.
A final loop was set-out in the Raja area, using drillholes PAL0171 and PAL0355 (loop 5; see figure 1). A smaller, 70m by 110m sized, ‘off-hole' conductive anomaly was measured on the mid-northern margin of the Raja zone of gold-cobalt mineralization. Modelling of the conductive anomaly places a plate-anomaly in the footwall of the Raja zone of mineralization, only 30 metres below the known zone by approximately (refer to Figure 5). While this general area has received some drilling previously, no drilling has penetrated the specific area defined in the modelled EM plate, and as such presents a very compelling drill-target.
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).
Technical Background
At Rajapalot, all examples of gold-cobalt mineralization are consistently located within highly-sheared and foliated wall-rocks adjacent to strongly hydrothermally altered, northwest to north dipping shear-zones. Mineralization 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 mineralization 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 mineralization remains open at depth across the entire project.

A strong, deep, ‘off-hole' conductor is found extending northwards from drillhole PAL0073. Shallow ‘in-hole' conductors are also found however, these represent the occurrence of un-mineralized, but heavily conductive pyrrhotite-bearing graphitic rock-units.
