Mawson Drills 4.9 metres @ 18.0 g/t Gold and 1,236 ppm Cobalt in Deepest Intersection at Palokas, Finland

VANCOUVER, BC / ACCESSWIRE / May 27, 2020 / Mawson Resources Limited ("Mawson") or (the "Company") (TSX:MAW)(Frankfurt:MXR)(OTC PINK:MWSNF) is pleased to announce further high-grade gold and cobalt results from five additional holes from the Palokas prospect, drilled during the recent 14.1 kilometre winter drill program at the Company's 100%-owned Rajapalot project in Finland.

Highlights:

• The deepest mineralized intersection drilled at Palokas to date, PAL0236, intersected 4.9 metres @ 18.0 g/t gold, 1,236 ppm cobalt, 18.8 g/t gold equivalent ("AuEq") from 449.7 metres including 2.0 metres at 31.2 g/t gold from 452.6 metres (Tables 1-4, Figures 1-3);
  • PAL0236 is located 360 metres vertically and 450 metres down plunge from the surface, 250 metres from the 2018 inferred resource (>2 g/t lower-cut) and 140 metres NW and down plunge from previously reported drill hole PAL0222 8.2 metres @ 19.1 g/t Au, 1,572 ppm cobalt, 20.1 g/t AuEq from 266.9 metres and 190 metres from PAL0228 7.0 metres @ 17.0 g/t gold, 2,168 ppm cobalt, 18.4 g/t AuEq from 251.4 metres;
• Drill hole PAL0216 located 24 metres north east of PAL0222 at Palokas returned 4.0 metres @ 6.0 g/t gold, 456 ppm cobalt, 6.3g/t AuEq from 262.0 metres, 1.0 metres @ 3.2 g/t gold from 273.9 metres and 2.0 metres @ 7.4 g/t gold from 319.0 metres (Tables 1-4, Figures 1-3);

Mr. Hudson, Chairman and CEO, states, "Drilling continues to return impressively high-grade intersections with 4.9 metres @ 18.0 g/t gold and 1,236 ppm cobalt in our deepest intersection to date from Palokas. The project continues to demonstrate grade and width with significant step-outs, while also demonstrating considerable room for expansion, particularly down plunge and southwards towards the South Palokas prospect. Geological modelling based on core logging and assaying remains on schedule to deliver an updated resource at Rajapalot at the start of Q3 2020."

Gold and cobalt assay results from five drill holes from Palokas prospect are released here (PAL0215, 0216, 0231, 0233 and 0236). The 2020 winter drill program consisted of 37 drill holes for 14,132 metres (including one wedged drill hole and deepening an existing hole). To date Mawson and has released results from 29 drill holes on 20^th January, 5^th and 28^th February, 9^th March, 20^th April, 2020 and here. Eight drill holes remain to be reported.

Distinct high-grade zones within the larger mineralized footprint at Palokas-South Palokas are becoming more evident as drill results are returned. PAL0236 adds more strength to the high grade-width intersections of Table 4 (2 g/t gold lower cut) intersections drilled to date at Rajapalot. The high-grade intersections from the 2020 drill campaign are a significant addition to the Palokas prospect (Figures 2 & 3). These include drill hole PAL0222 (8.2 metres @ 19.1 g/t Au, 1,572 ppm cobalt, 20.1 g/t AuEq), the plunge extent is defined from the shallower intersection in PAL0228 (7.0 metres @ 17.0 g/t gold, 2,168 ppm cobalt, 18.4 g/t AuEq), towards PAL0236 and PAL0194 (7.8 metres @ 5.1 g/t Au, 4,454 ppm cobalt, 7.9 g/t AuEq from 425.1 metres). The continuity of these high-grade trends is encouraging as the Company learns more about the detailed distribution of mineralization. All three prospect areas with inferred resources at Rajapalot remain open, with further drilling required.

Further results reported here from the Palokas prospect include PAL0215 intersected 3.8 metres @ 0.7 g/t gold, 194 ppm cobalt, 0.9 g/t AuEq from 294.9 metres and PAL0231 intersected 2.3 metres @ 3.1 g/t gold, 272 ppm Co, 3.1 g/t AuEq from 342.0 metres. PAL0233 contained no significant mineralization.

A plan view of the completed drill holes and the locations of drill holes reported here are shown in Figures 1-3 with corresponding collar and assay data in Tables 1-3. Intersections in the plan view (Figure 2) and oblique section in Figure 3 are coloured by AuEq grade to show the higher grade zones at Palokas and South Palokas.

Assuming a predominant stratabound control, the true thickness of the mineralized interval is interpreted to be approximately 90% of the sampled thickness. Gold-only intersections are reported with a lower-cut of 0.5 g/t gold over a 1 metre width. No upper cut-off was applied. Where cobalt data becomes available, a lower cut of 0.3 g/t AuEq is used, based on modifying the open pit Whittle^TM optimized open pit lower cut-off grade of 0.37 g/t AuEq developed for the 2018 resource recalculated to a dollar value per tonne against current averaged gold and cobalt prices (and therefore the 2018 resource cutoff 0.37 g/t AuEq is the same value per tonne as 0.30 g/t AuEq today). Where gold is below detection limit, half the cutoff grade is used in calculating the average grade for an interval and in determining the gold equivalent value.

Technical and Environmental Background

Up to five diamond drill rigs from the Arctic Drilling Company OY ("ADC") and Kati OY ("Kati") 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.

Three-month average gold and cobalt prices have been used to calculate AuEq values according to the following:

• Average gold price $1,580 per oz
• Average cobalt price $14.50 per pound
• Resulting in gold equivalent formula of AuEq g/t = Au g/t + (Co ppm/1,589).

The host rocks to the gold and cobalt mineralization comprise sulphides (pyrrhotite>>pyrite) with biotite-muscovite-chlorite schists at South Palokas and Mg-Fe amphibole-biotite-chlorite rocks at Palokas. 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 minerals 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).
