VANCOUVER, November 10, 2020 - Mawson Gold Ltd. ("Mawson" or the "Company") (TSX:MAW)(Frankfurt:MXR)(OTC PINK:MWSNF) is pleased to announce it has discovered high-grade gold for the first time at the Joki East prospect at the 100% owned Rajapalot Project in Finland. Joki East is located 1,600 metres north-east of the Raja resource area and is permitted for year-round drill access (Figure 1).
Key points:
-
PAL0241, the discovery drill hole at Joki East, returned 1.6 metres @ 28.3 g/t gold from 168.6 metres;
-
A total of eight drill holes have been completed at Joki East, with the first two holes reported here (PAL0240-241). Visible gold has been identified in 4 of the 8 drill holes completed to date, including PAL0241;
-
Holes drilled to date define a body of 50-60 metres across strike and 120 metres down plunge within a modelled electromagnetic ("EM") plate with dimensions of 300 metres by 140 metres. Mineralization remains open in all directions. The body plunges at 25 degrees to the NW, a similar orientation to the mineralized bodies defined in the resources areas at Rajapalot. Mineralization is thin but high-grade;
-
Drilling this autumn in Finland consisted of 11 diamond drill holes for 2,344.6 metres, at both the Joki East and Hirvimaa areas. Drilling was targeted using the inferred location of the stratigraphic host to the gold-cobalt mineralization, combined with base-of-till drill hole gold anomalies, conductors first recognized in airborne electromagnetic ("VTEMplus"), and then followed up by ground EM surveys (Figure 1);
-
A 18 kilometre drill program is planned to commence from late November 2020 with the aim to find additional resource areas and expand the Sept 2020 Mineral Resource, which doubled the resource published 20 months earlier;
-
Electromagnetic ("EM") geophysical surveys remain in progress, covering the entire 2 kilometre trend at Joki East and other prospective areas (Figure 1);
Mr. Hudson, Chairman and CEO, states: "This is a game changer. We have been waiting to drill gold mineralization over a much larger area and into all year round permitted drill areas, outside Natura 2000, for several years. As the project pivots towards further resource expansion and early stage economic studies, having the ability to drill year-round will become a key to faster potential project development. The new discovery at Joki East also demonstrates that our exploration methodology, underpinned by geological understanding, combined with base-of-till drilling, EM geophysics and follow up diamond drilling forms a very effective discovery tool, which opens up the prospectivity of the project even further. We now look forward to the 18 kilometre resource-expansion drill program planned to start in late November in Finland."
In total, 11 diamond drill holes for 2,344.6 metres were completed during the autumn program, as initially announced on September 23, 2020. This included eight holes at Joki East (PAL0240-247) for 2084.7 metres, while 2 holes (PAL0237-238) for 218.2 metres were also drilled at Hirvimaa. PAL0239 was abandoned at 41.7 metres at Joki East and redrilled as PAL0240.
Drill holes PAL0237 and PAL0238, both drilled at Hirvimaa, contained no significant gold, but returned 2 metres @ 95.9 ppm cobalt from 42.1 metres and 1 metre @ 138.6 ppm cobalt from 109.5 metres, respectively, in the distal mineralized position. PAL0240, the first hole drilled into a ground EM anomaly recently identified by Mawson at Joki East, identified the correct prospective stratigraphy with 2-5% pyrrhotite in a biotite bearing calc-silicate metasediment from 165.1-167.5 metres and gave confidence for further drill testing. Low grade and sporadic gold was subsequently assayed within a broad downhole interval between 88.8 metres to 176.3 metres in PAL0240 with the best result of 1 metre @ 0.9 g/t gold from 148.8 metres in an oxidized albitic calc-silicate breccia, all suggestive of a near miss intersection. Downhole EM was subsequently performed within PAL0240 and showed a strong off-hole conductive response which aided in targeting additional drill holes at Joki East.
PAL0241, the second and discovery hole at Joki East, drilled 32 metres NE from PAL0240 within the modelled EM conductive plate returned 1.6 metres @ 28.3 g/t gold from 168.6 metres. From the eight holes drilled to date into Joki East, visible gold has been identified in 4 holes (PAL0241, PAL0242, PAL0245 and PAL0247). Drilling is paused for 4 weeks, to assess results and undertake further geophysical surveys. One drill rig will return to Rajapalot in late November, with 4 rigs in total to be mobilized in late December 2020-early January 2021. Further drill results will be released as they become available.
The host rocks to the gold mineralization at Joki East are similar to mineralization observed 1.6 kilometres to the west at the Raja and Palokas resource areas, and comprise sulphides (pyrrhotite>>pyrite) with biotite-albite schists and Mg-Fe amphibole-biotite-chlorite rocks +/- scheelite. Veining and fracture fill minerals include pyrrhotite, pyrite and minor chalcopyrite (+/- quartz, visible gold). Retrograde chlorite after amphibole and vein-controlled chlorite-biotite are also present. Altered rocks enclosing the mineralized package contain locally minor talc.
Technical and Environmental Background
One drill rig from Nivalan Timanttikairaus Oy with water recirculation and drill cuttings collection systems was 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.
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. 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.
All maps have been created within the KKJ3/Finland Uniform Coordinate System (EPSG:2393).

Scheelite fluoresces under the ultraviolet light and glows a bright sky-blue. Scheelite is always spatially associated with gold at Rajapalot, and is used by Mawson geologists in the search for potential gold-bearing zones in drill core. Scale of core is NQ2 (50.7 mm diameter).
