Mawson Summarizes Successful 2021 Drilling at Rajapalot, Finland

VANCOUVER, BC / ACCESSWIRE / August 23, 2021 / Mawson Gold Limited ("Mawson") or (the "Company") (TSX:MAW)(Frankfurt:MXR)(OTC PINK:MWSNF) is pleased to summarize drill results from the Company's 76 hole, 19,422 metre 2020/21 drill program at the Company's 100%-owned Rajapalot gold-cobalt project in Finland (Figure 1).

Key Results:

• The soon to be released Rajapalot resource update will cover eight prospect areas (The Hut, Terry's Hammer, Rumajärvi, Palokas, South Palokas, Raja, Uusisaari and Joki E). The 2020/21 drill program has 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 (Figure 1);
• 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.

Key results from the program include (Figure 1):

• Drill delineation of coherent gold-cobalt zones at the Hut and Joki East , which are located 500 metres and 1,500 metres respectively from the closest Inferred Mineral resource areas (Figure 1).
  • 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 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 which intersected 1.6 metres @ 28.3 g/t gold ("Au") and 1,190 ppm cobalt ("Co") , 29.2 g/t gold equivalent ("AuEq") from 168.6 metres;
  • At the Hut , a new discovery delivered the thickest mineralized zone drilled to date at Rajapalot with PAL0259 intersecting 70.3 metres @ 0.9 g/t Au, 828 ppm Co, 1.6 g/t AuEq from 95.8 metres (no lower cut-off applied). Follow up drilling included 3.6 metres @ 7.4 g/t Au, 2,290 ppm Co, 9.4 g/t AuEq from 207.7 metres in PAL0301;
• At South Palokas significant extensions of mineralization were discovered, with intersections drilled 290 metres down-plunge. Mineralization remains open. Highlights included:
  • PAL0235 intersected 15.3 metres @ 3.0 g/t Au, 998 ppm Co, 3.9 g/t AuEq from 439.5 metres;
  • PAL0303 was drilled 120 metres down-plunge from PAL0235 and intersected 30.8 metres @ 3.9 g/t Au, 1,403 ppm Co, 5.1 g/t AuEq from 553.2 metres.
• At the Raja project shallow holes drilled on a 90-metre-wide cross section were targeted to test an undrilled area. These results more than double the grade and thickness of the shallow parts of the Raja prospect. Highlights included:
  • Drill hole PAL0297 intersected 20.7 metres @ 7.4 g/t Au, 111 ppm Co, 7.5 g/t AuEq from 74.0 metres;
  • Drill hole PAL0295 intersected 15.7 metres @ 3.8 g/t Au, 783 ppm Co, 4.5 g/t AuEq from 53.3 metres;
• Early stage drilling also defined new high-grade gold-cobalt intersections with electromagnetic conductors that will provide a large upside for increasing the resource base in future drill campaigns.
  • At Terry's Hammer prospect PAL0273 intersected 9.3 metres @ 1.5 g/t Au, 422 ppm Co, 1.9 g/t AuEq from 14.6 metres;
  • At the Rumajärvi prospect PAL0258 intersected 3.0 metres @ 8.3 g/t Au, 283 ppm Co, 8.6 g/t AuEq from 66.9 metres and PAL0267 intersected 27.5 metres @ 0.7 g/t Au, 443 ppm Co, 1.0 g/t AuEq from 30.3 metres.

Mr. Michael Hudson, Chairman and CEO states, "Our 2021 drilling program has delivered more economic grade/width intersections than ever before. We have discovered 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. Our Rajapalot gold camp is expanding rapidly, allowing us to extend our successful exploration strategy across the full 100 square kilometre property. Drill success has continually increased through recognition of strong linear late 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. A resource upgrade is due before the end of August."

Mawson completed 76 holes for 19,422 metres during the 2020/21 winter drill season. Results from all holes are provided in Tables 1 and 3 below. At the completion of the 2020/21 winter drill program a total of 544 drillholes for 84,507 metres has been drilled at the Rajapalot project with an average depth of 155 metres. The top 30 intersections in the project to date are shown in Table 2. Key results from the program are outlined below.

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 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.

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 1 metre for mineralized samples and 2 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 US$1,599 per oz
• Average cobalt price US$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 2 metre lower cut. No upper cut-off was applied, and higher-grade intersections use a 1.1 g/t AuEq lower cut over 2 metres.
