Mawson’s Subsidiary SXG Reports Continued High Grade Zones to 840 meters at Sunday Creek, Victoria, Australia

The bottom portion of the hole, reported here, has identified 4 new and separate mineralized zones containing assays up to 95.6 g/t Au and with multiple visible gold intersections (photos 1-4). SDDSC050 now has a total of thirteen vein sets and sixteen intersections > 20 g/t Au over a > 0.5 km interval from 319.2 (520.8 m @ 1.7 g/t AuEq no lower cut).

Highlights:

• Mineralization extended from 651 m to 840 m, with 520.8 m between the first and last mineralized interval.
• Better assays from the bottom portion of hole, reported here, from 651 m – 923.7 m (end of hole) included:
  – 3 m @ 54.6 g/t AuEq (54.6 g/t Au, 0.1 %Sb) from 667.1 m
  – 0 m @ 7.3 g/t AuEq (7.2 g/t Au, 0.1 %Sb) from 712.0 m
        including 5 m @ 41.5 g/t AuEq (41.3 g/t Au, 0.1 %Sb) from 713.0 m
  – 9 m @ 8.8 g/t AuEq (8.7 g/t Au, 0.1 %Sb) from 835.1 m
        including 8 m @ 22.8 g/t AuEq (22.7 g/t Au, 0.1 %Sb) from 837.2 m
• Four new and separate mineralized zones (see also Figure 1) have been intersected in the lower portion of the hole reported here, for a total of thirteen veins sets found within SDDSC050
• SDDSC050 is the deepest hole on the project by 278 m. Of note in the lower third of SDDSC050 is the changing nature of mineralization with thick quartz carbonate veins up to 1 m wide with gold and arsenic, but no antimony mineralization. This is a typical change in epizonal deposits in Victoria which transition from gold-antimony to gold only zones at depth (Figure 4).
• Drilling with three rigs is in progress at the Golden Dyke, Rising Sun and Apollo prospects. Nine drill holes are being geologically processed and analysed.
• Mawson will own 51% of SXG following final close of SXG’s recent A$16.0 million capital raise. Mawson’s 93.75 million SXG shares have a market value of A$68 million (C$62 million) based on SXG’s closing price on December 14, 2022.

Ivan Fairhall, Mawson CEO, states: “This completes an incredible hole at Sunday Creek, demonstrating 13 vein sets over a > 0.5 km interval – which expands the project footprint both along strike and to depth in the deepest drilling on the project to date. Importantly, at depth the deposit is transitioning with wide quartz carbonate gold-bearing veins observed with gold, but no antimony – consistent with changes in other prominent epizonal deposits in the region such as Fosterville and Costerfield, two of the highest grade gold mines on earth.

Southern Cross is well capitalized following its recent raise and represents an asset of considerable value in Mawson’s portfolio, which also includes also the 100% owned Rajapalot project whose recent PEA delivered a US$211 million after-tax NPV5.

Results Discussion

The Sunday Creek epizonal-style gold project is located 60 km north of Melbourne within 19,365 hectares of granted exploration tenements. SXG is also the freehold landholder of 132.6Ctoni hectares that forms the key portion in and around the drilled area at the Sunday Creek Project.

Drill hole SDDSC050 was originally designed by SXG to test under the Rising Sun shoot (from 319.2 – 349.0 m), however the hole continued in mineralization to test a never-before-drilled area between Rising Sun and Apollo. With 100% of the assays returned for hole SDDSC050, it illustrates thick and multiple zones of high-grade mineralization and changes in mineralization style with depth, seen elsewhere in the region. The drill hole also intersected 16 high-grade intersections >20 g/t Au, including 5 high-grade intersections >100 g/t Au. Summary grades are outlined in the highlights section above and in Table 2.  SDDSC050 is parallel to the host breccia dyke but at a high angle to the predominant NW high-grade mineralization trend and therefore the true thickness of the mineralized interval is interpreted to be approximately 60-70% of the sampled thickness.

Also reported here is drillhole SDSC048A, delivering a solid result and also considered by SXG to be a near-miss drill hole at depth in the Apollo area, with over 230 m of anomalous sulphidic (arsenic) mineralization. Better gold and antimony results included:

• 5 m @ 2.3 g/t AuEq (1.3 g/t Au, 0.6 %Sb) from 493.5 m
  – Including 0.4 m @ 15.9 g/t AuEq (2.5 g/t Au, 8.5 %Sb) from 493.5 m
  – Including 0.4 m @ 8.7 g/t AuEq (6.3 g/t Au, 1.5 %Sb) from 500.0 m

Figures 2-4 show project location and plan and longitudinal views of drill results reported here and Tables 1–3 provide collar and assay data. The true thickness of the mineralized interval is interpreted to be approximately 60-70% of the sampled thickness.

Mineralization Transition at Depth

The transition from gold + stibnite +/- arsenopyrite to gold + arsenopyrite marks a change in temperature within the system. The transition observed in SDDSC050 correlates with the typical transition in epizonal deposits in Victoria and potentially indicates what may come at depth as drilling continues.

Technical Background and Qualified Person

The Qualified Person, Michael Hudson, Executive Chairman and a director of Mawson Gold, and a Fellow of the Australasian Institute of Mining and Metallurgy, has reviewed, verified and approved the technical contents of this release.

Analytical samples are transported to the Bendigo facility of On Site Laboratory Services (“On Site”) which operates under both an ISO 9001 and NATA quality systems. Samples were prepared and analyzed for gold using the fire assay technique (PE01S method; 25 gram charge), followed by measuring the gold in solution with flame AAS equipment. Samples for multi-element analysis (BM011 and over-range methods as required) use aqua regia digestion and ICP-MS analysis. The QA/QC program of Southern Cross Gold consists of the systematic insertion of certified standards of known gold content, blanks within interpreted mineralized rock and quarter core duplicates. In addition, On Site inserts blanks and standards into the analytical process.

Gold equivalent “AuEq” for Sunday Creek is = Au (g/t) + 1.58 × Sb (%) based on assumed prices of gold US$1,700/oz Au and antimony US$8,500/metal tonne, and total year metal recoveries of 93% for gold and 95% for antimony. Given the geological similarities of the projects, this formula has been adopted to align to TSX listed Mandalay Resources Ltd Technical Report dated 25 March 2022 on its Costerfield project, which is located 54 km from Sunday Creek and which historically processed mineralization from the property.
