Mawson Intersects 15.3 metres at 3.0 g/t gold, 998 ppm cobalt and 11.0 metres at 4.0 g/t gold, 756 ppm cobalt at South Palokas, Finland

VANCOUVER, BC / ACCESSWIRE / June 29, 2021 / Mawson Gold Limited ("Mawson") or (the "Company") (TSX:MAW)(Frankfurt:MXR)(OTC PINK:MWSNF) is pleased to announce new results from three drillholes from the South Palokas prospect, completed during the recent 19.4 kilometre drill program at the Company's 100%-owned Rajapalot project in Finland. These increase the mineralized footprint and improve continuity of previous high-grade intersections.

Highlights:

• Results are presented here for three diamond drill holes totalling 853.5 metres from the South Palokas prospect as part of the Company's 76-hole, 19,422 metre 2020/21 drill program at the Company's 100%-owned Rajapalot project in Finland (Figure 1).
• PAL0235 intersected 15.3 metres @ 3.0 g/t Au, 998 ppm Co, 3.9 g/t AuEq from 439.5metres including 2.0 metres @ 11.2 g/t Au, 1,019 ppm Co, 12.0 g/t AuEq from 447.5 metres:
  • PAL0235 significantly opens up high-grade gold potential at depth at South Palokas. The closest high-grade drill hole, located 160 metres up plunge from PAL0235, was previously reported PAL0213 (17.7 metres @ 3.8 g/t Au, 880 ppm Co, 4.3 g/t AuEq from 293.0 metres and 6.0 metres @ 9.2 g/t Au, 1,364 ppm Co, 10.0 g/t AuEq from 317.0 metres;
  • PAL0235 was deepened this drill season following its early termination at 176.9 metres last drill season owing to the spring thaw in 2020;
• PAL0288 intersected 11.0 metres @ 4.0 g/t Au, 756 ppm Co, 4.6 g/t AuEq from 119.0metres (vertical depth 105 metres), including 4.0 metres @ 9.6 g/t Au, 676 ppm Co, 10.1 g/t AuEq from 124.0 metres.
  • PAL0288 was drilled on a section between holes PAL0122 and PAL0204 (17.7 metres @ 3.8 g/t Au, 880 ppm Co from 293.0 metres ) that lies within the confines of the Whittle Constrained pit published as part of the 2020 Inferred Mineral Resource .
• PAL0290 intersected 20.0 metres @ 1.7 g/t Au, 529 ppm Co, 2.1 g/t AuEq from 240.0 metres, including 11.6 metres @ 2.8 g/t Au, 541ppm Co, 3.2 g/t AuEq from 242.0 metres;
  • PAL0290 was drilled 30 metres to the west of PAL0173 ( 17.0 metres @ 3.0 g/t Au, 827 ppm Co, 4.3 g/t AuEq ) to determine the grade and western extents of the mineralization beyond the 2020 Inferred Mineral Resource;
• A total of 47 drill holes for 11,746 metres from five individual prospect areas remain to be reported through July/August 2021, with a resource upgrade scheduled during August 2021;
• In other important news, new mise-á-la-masse geophysical work (physical property = electrical conductivity) at Palokas and South Palokas indicates electrical connectivity based on cross-hole measurements. The continuity of the stratabound gold-cobalt package between both prospects further enhances the prospectivity between the two locations.

Mr. Hudson, Chairman and CEO, states, "The South Palokas prospect has always held promise of delivering more high-grade gold and cobalt assays. These results add to the deeper and untested western limits of the South Palokas mineralization and show the potential to substantially grow the Rajapalot resource. As assay results from the 2021 drill season continue to flow in, the geological team is adding to, or building new, mineralized wireframes to form part of the updated Inferred Mineral Resource we expect to publish in Q3 this year."

South Palokas lies approximately 400 metres southwest of the discovery outcrop at the Palokas prospect (Figure 1). Gold and cobalt assay results are reported here from three holes for 853.5 metres from the 2020/21 drill program, which is now complete. In total, since drilling commenced in September 2020, Mawson drilled 76 drillholes for 19,422 metres. Eleven holes for 2,345 metres were reported in late 2020 and a further 15 holes for 4,478 metres were reported in April 2021 (Table 1). A total of 47 drill holes for 11,746 metres from five individual prospect areas remain to be reported through to July/August 2021, with a resource upgrade scheduled for July-August 2021. Specifically, holes released here are from South Palokas (PAL0235, PAL0288, PAL0290). A full set of reported results and assay data are shown in Tables 2 and 3.

Technical and Environmental Background

Four diamond drill rigs from Kati Oy, Nivalan Timanttikairaus Oy and MK Core Drilling Oy all with water recirculation and drill cuttings collection systems are used in the 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 averaging one metre for mineralized samples and two metres for barren samples are cut in half at the Geological Survey of Finland (GTK) core facilities in Rovaniemi, Finland. The remaining half core is retained for verification and reference purposes. Analytical samples are transported by commercial transport from site to the CRS Minlab Oy 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 Minlab, then transported by air to the MSA labs in Vancouver, Canada and analyzed using four acid digest ICP-MS methods. The QA/QC program of Mawson consists of the systematic insertion of certified standards of known gold content, duplicate samples by quartering the core, and blanks the within interpreted mineralized rock. In addition, CRS inserts blanks and standards into the analytical process.

Spot gold and cobalt prices have been used to calculate AuEq values according to the following:

• Average gold price $1,599 per oz
• Average cobalt price $19.93 per pound
• Resulting in gold equivalent formula of AuEq g/t = Au g/t + (Co ppm/1,170).

The host rocks to the gold and cobalt mineralization comprise sulphides (pyrrhotite>>pyrite) with biotite-muscovite-chlorite schists and Mg-Fe amphibole-biotite-chlorite rocks. Veining and fracture fill minerals include pyrrhotite, magnetite and magnetite-pyrrhotite (+/- quartz, tourmaline). Retrograde chlorite after biotite, generations of secondary muscovite ("sericite") and vein-controlled chlorite+/- tourmaline and magnetite are also present. Preliminary hand-held XRF analysis confirms the presence of associated scheelite and molybdenite, the former visible under UV light as tiny veinlets and disseminations. The silicate mineral alteration assemblages associated with the gold are clearly post-metamorphic, reduced, and most likely driven by hydrothermal fluids from nearby granitoid intrusions. Chlorite and fine muscovite are regarded as the lowest temperature silicate minerals with gold, structurally controlled in apparent spatial association with quartz and/or K-feldspar veins. Altered rocks enclosing the mineralized package contain locally abundant talc and tourmaline.

All maps have been created within the KKJ3/Finland Uniform Coordinate System (EPSG:2393).

Tables 1-2 provide collar and assay data. Assuming a predominant stratabound control, the true thickness of the mineralized interval is interpreted to be approximately 90% of the sampled thickness. Table 3 gives detailed individual assays of all intervals reported in this press release. Intersections are reported with a lower cut of 0.3 g/t AuEq over two metre lower cut, except where noted no lower cut was applied. No upper cut-off was applied, and higher-grade intersections use a 1.1 g/t AuEq lower cut over two metres.
