Mawson Defines Two New Areas in First Winter Drilling Results from Finland Drills 70.3 m @ 1.6 g/t AuEq at The Hut and 1.5 m @ 19.6 g/t AuEq at Joki East

VANCOUVER, BC / ACCESSWIRE / April 12, 2021 / Mawson Gold Limited ("Mawson") or (the "Company") (TSX:MAW) (Frankfurt:MXR) (PINKSHEETS: MWSNF) is pleased to announce results from two new areas that are located outside and adjacent to current resource areas. These results deliver the thickest mineralized zone found at Rajapalot to date at The Hut and continue to extend high-grade mineralization at Joki East. Fifteen diamond drill holes are reported 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.

Highlights:

• Results are presented for two new discovery areas: The Hut and Joki East, that are located outside and adjacent to current resource areas at Rajapalot (Figure 1);
• At Joki East, a blind discovery made by Mawson in late 2020, high grade mineralization has been drilled at the shallowest levels yet found;
  • Drill hole PAL0252 intersected 1.5 metres @ 18.1 g/t Au, 1,696 ppm Co, 19.6 g/t AuEq from 117.1 metres;
  • Mineralization at Joki East now extends over 225 metres down plunge and 30-40 metres across strike with mineralization open up- and down-plunge;
• A new discovery has been drilled in PAL0259 at The Hut prospect and delivers the thickest mineralized zone drilled to date at Rajapalot;
  • Drill hole PAL0259 intersected 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);
    • Including 23.3 metres @ 1.2 g/t Au, 1,035 ppm Co, 2.1 g/t AuEq from 100.7 metres;
    • Including 14.4 metres @ 0.6 g/t Au, 1,531 ppm Co, 1.9 g/t AuEq from 126.3 metres;
    • Including 2.4 metres @ 3.9 g/t Au, 747 ppm Co, 4.6 g/t AuEq from 143.3 metres;
    • Including 7.0 metres @ 1.1 g/t Au, 31 ppm Co, 1.2 g/t AuEq from 159.0 metres;
  • Drill hole PAL0263, drilled 70 metres down plunge and north of PAL0259, intersected:
    • 13.6 metres @ 1.2 g/t Au and 98 ppm Co (1.3 g/t AuEQ) from 103.0 metres;
      • including 2.7 metres @ 5.0 g/t Au, 264 ppm Co, 5.3 g/t AuEq from 104.8 metres;
    • 4.3 metres @ 2.3 g/t Au, 26 ppm Co, 2.3 g/t AuEq from 121.5 metres;
    • 9.2 metres @ 1.1 g/t Au, 256 ppm Co, 1.3 g/t AuEq from 222.3 metres;
      • including 2.0 metres @ 4.3 g/t Au, 170 ppm Co, 4.4 g/t AuEq from 227.3 metres;
  • Drill hole PAL0269, drilled 50 metres north-west from PAL0263 intersected:
    • 15 metres @ 1.0 g/t Au, 307 ppm Co, 1.3 g/t AuEq from 195.9 metres;
      • including 6.0 metres @ 2.1 g/t Au, 501 ppm Co, 2.5 g/t AuEq from 198.9 metres; and
    • 3.0 metres @ 3.1 g/t Au, 13 ppm Co, 3.1 g/t AuEq from 219.4 metres
• In total, since drilling commenced in September 2020, Mawson has drilled 76 drillholes for 19,422 metres. A total of 15 holes for 4,478 metres are presented here; and
  • A total of 50 drill holes for 12,600 metres from 5 individual prospect areas remain to be reported through to June 2021, with a resource upgrade scheduled for July 2021.

Mr. Hudson, Chairman and CEO, states, "After an active few months in the field, this is a strong start, delivering both high grades and thick gold-cobalt mineralization on new discoveries close to our already defined resource areas. These results show the potential to substantially grow the Rajapalot resource and we highly anticipate the additional results from 50 drill holes that will be reported from five individual prospect areas over the coming months."

The Hut and Joki East are located 500 metres and 1,500 metres respectively from the closest resource areas (Figure 1). Gold and cobalt assay results are reported here from 15 holes for 4,478 metres from the 2020/21 drill program, which is now complete. In total, since drilling commenced in September 2020, Mawson has drilled 76 drillholes for 19,422 metres. Eleven holes for 2,345 metres were reported in late 2020 (Table 1). Drilling with 4 rigs ramped up through February and March 2021. With the snow melt commencing in late March, the winter program drilling was completed just short of the planned 20,000 metres. A total of 50 drill holes for 12,600 metres from five individual prospect areas remain to be reported through to June 2021, with a resource upgrade scheduled for July 2021. Specifically, holes released here are from Joki East (PAL0249-254) and The Hut (PAL0255-257, PAL0259-260, PAL0263, PAL0265 and PAL0269). A full set of reported results is shown in Table 2.

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 $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 2 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 2 metres.
