• 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 (26 August 2021, available on SEDAR as filed by previous owner Mawson Gold Limited),), 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 (AuEq 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

The Rajapalot mineral resource update covers eight prospect areas (The Hut, Terry’s Hammer, Rumajärvi, Palokas, South Palokas, Raja, Uusisaari and Joki East). The 2020/21 drill program delivered more economic grade/width intersections than ever before and led to the discovery of two new gold-cobalt zones, delineated significant extensions to four more prospects with defined resources and added two further prospects suitable for wireframing and resource estimation.

Approximately 80% of the Rajapalot area, or 20 kilometres of mineralization-host package remains untested by drilling. Rajapalot forms a smaller part of Mawson’s larger 100 square kilometre Rompas-Rajapalot Finnish project area owned 100% by Mawson.

At the completion of the 2021 winter drill program, a total of 84,507 metres has been drilled at Rajapalot with the average depth now 155 metres. A total of 330 holes for 72.8 kilometres and an average depth of 250 metres were used in the upgraded August 2021 resource estimation. Whereas a total of 257 holes for 53.8 kilometres metres and an average depth of 209 metres were used the upgraded September 2020 resource estimation and a total of 178 holes for 24.0 kilometres with an average depth of 135 metres were used within the December 2018 maiden resource estimation.

Drill success has continually increased through recognition of strong linear structural controls to high-grade gold-cobalt mineralization and a strong correlation with electromagnetic conductors that provide a large potential for increasing mineral resources in future drill campaigns.

Joki East

Joki East is a blind discovery from 150 metres depth made by Mawson this drill season. Mineralization is thin but very high grade and extends over 225 metres down-plunge and 30-40 metres across strike. The mineralization is in an all-season drill area and remains open and untested up- and down-plunge. Mise-a-la-masse geophysics undertaken at Joki East has confirmed the shape and extent of the sulphidic gold-bearing body up plunge and demonstrated that mineralization shows good connectivity between drill holes. Key results included:

• PAL0241 intersected 1.6 metres @ 28.3 g/t Au and 1,190ppm Co, 29.2 g/t AuEq from 168.6 metres;
• PAL0242 returned 1.6 metres @ 19.2 g/t Au and 1,478ppm Co, 20.3 g/t AuEq from 155.0 metres;

At Raja, holes drilled on a 90-metre-wide cross section at the prospect were targeted to test an undrilled shallow area. These results more than double the grade and thickness of the shallow parts of the Raja prospect. The holes are located 250 metres up-plunge from PAL0093 that intersected 33.6 metres @ 8.0 g/t Au and 823 ppm Co from 243.0 metres (press release of June 27, 2018).

New earlier stage targets

Early stage drilling also defined new high-grade gold-cobalt intersections with electromagnetic conductors that will provide upside for increasing the resource base in future drill campaigns.

• At Terry’s Hammer prospect PAL0273 drilled 9.3 metres @ 1.5 g/t Au, 422 ppm Co, 1.9 g/t AuEq from 14.6 metres;and

Diamond Drilling

A total of 76,155 drilling metres (90% of total) has been completed since 2017. A total of 330 holes for 72.8 kilometres and an average depth of 250 metres were used in the upgraded August 2021 resource estimation. In comparison, a total of 257 holes for 53.8 km and an average depth of 209 metres were used the upgraded September 2020 resource estimation and a total of 178 holes for 24.0 km with an average depth of 135 metres were used within the December 2018 maiden resource estimation.

Geology

The host sequence comprises a polydeformed, isoclinally folded package of moderately to strongly metamorphosed Paleoproterozoic supracrustal rocks of the Peräpohja belt. The Paleoproterozoic of northern Finland are highly prospective for gold and cobalt, and include the Europe’s largest gold mine, Kittilä, operated by Agnico Eagle Finland Oy.

Prospects with high-grade gold and cobalt at Rajapalot occur across 3 km (east-west) by 2 km (north-south) area within the larger Rajapalot project exploration area measuring 4 km by 4 km with multiple mineralized boulders, base-of-till (BOT) and rare outcrops. High-grade Au-Co mineralization at Rajapalot has been drilled to 540 metres deep at Raja and South Palokas prospects but is not closed out at depth in any prospect. The only surface exposure of mineralization is at Palokas, however except for East Joki, all mineralization comes to the top of the bedrock below the till, less than 6 metres below the surface. East Joki is 110 metres from the surface at its shallowest but is not drilled yet in the up-dip direction.

Mawson’s primary target type across the whole Rajapalot-Rompas area is the disseminated Au-Co style, with Mawson’s geological team in Finland devoted to uncovering more prospects based on their increased understanding of the host sequence.

Two distinct styles of gold mineralization dominate the Rajapalot area. The first, is a variably sulphidic magnesian-iron host, previously referred to internally as “Palokas” style. The magnesian-iron host is most likely an ultramafic volcanic (komatiitic) and occurs within approximately 100 vertical metres of the inferred Kivalo-Paakkola boundary (that is, near the incoming of pelites, calc-pelites and quartz muscovite rocks). A largely retrograde mineral alteration assemblage includes chlorite, Fe-Mg amphiboles (anthophyllite and cummingtonite series), tourmaline and pyrrhotite commonly associated with quartz-veining. Subordinate almandine garnet, magnetite and pyrite occur with bismuth tellurides, scheelite, ilmenite and gold, cobalt pentlandite and cobaltite. Metallurgical testing at Palokas reveals the gold to be non-refractory and 95% pure (with minor Ag and Cu) with excellent recoveries by gravitational circuit with conventional cyanidation and/or flotation. QEMSCAN studies also show that the gold occurs as native grains, found both on grain boundaries and within minerals. Detailed work by Jukka Pekka Ranta of the University of Oulu (plus co-workers) on fluid inclusions and the host rocks to the Fe-Mg mineralization at Palokas indicates weakly saline, methane-bearing fluids at depths as shallow as 5 km and temperatures of approximately 250 degrees were responsible for deposition of the gold.

The second style of gold-cobalt mineralization at Rajapalot, a potassic-iron (K-Fe) style (formerly referred to internally as “Rumajärvi” type) is characteristically associated with muscovite and / or biotite and chlorite in a diverse range of fabrics. Gold grades of more than 1 g/t Au are associated with pyrrhotite and contained within muscovite-biotite schists, muscovite and biotite bearing albitic granofels and brecciated, variably micaceous albitic rocks. Magnetite is a common mineral, but not a necessity for anomalous gold grades. The host rocks are grey to white owing to their reduced nature and may be enclosed by light pink to red calcsilicate-bearing albitites. To date, the K-Fe gold-cobalt mineralization style has been intersected near the muscovite-bearing quartzite at Raja and Rumajärvi, but as other rock types are also mineralized and the clear strong structural control on grade, stratigraphic constraints may locally not be relevant.

Exploration for Palokas and Rumajärvi style gold prospects is not restricted to the Rajapalot area. Recognition of the host stratigraphic package (near the boundary of the Kivalo-Paakkola Group boundary) enclosing the 6 km long vein-hosted Rompas Au-U system increases the search space for the pyrrhotite-Au-Co systems to cover Mawson’s full permit area. The geochemical characteristics of the ultramafic volcanics and related intrusives are not only present in the southern drill section at South Rompas but have more than 50 km of strike length in Rompas-Rajapalot. It is the interaction of this reactive rock package with late gold-bearing hydrothermal systems driven by ca. 1.8 Ga granitoids, that now form the most highly prospective targets away from the Rajapalot area. The cobalt component of the system is largely stratabound and formed much earlier, most likely from oxidized saline basinal fluids interacting with reduced strata.
