NEWS RELEASE December 14, 2022

Mawson’s Subsidiary SXG Reports Continued High Grade Zones

to 840 meters at Sunday Creek, Victoria, Australia

Vancouver, Canada — Mawson Gold Limited (“Mawson” or the “Company”) (TSX: MAW) (Frankfurt: MXR)

(PINKSHEETS: MWSNF) announces further high-grade gold mineralization from new assays reported from the lower

third of drill hole SDDSC050 from 651 m to 923.7 m at the 100%- owned Sunday Creek Project in Victoria (Figure 2).

The top two thirds of SDDSC050 from 0 m to 651 m was reported on 21 November 2022 with a highlig ht 305.8 m @

2.4 g/t AuEq (1.6 g/t Au, 0.5% Sb) from 319.2 m, and included 12 high-grade intersections >20 g/t Au.

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:

o 0.3 m @ 54.6 g/t AuEq (54.6 g/t Au, 0.1 %Sb) from 667.1 m

o 9.0 m @ 7.3 g/t AuEq (7.2 g/t Au, 0.1 %Sb) from 712.0 m

 including 1.5 m @ 41.5 g/t AuEq (41.3 g/t Au, 0.1 %Sb) from 713.0 m

o 4.9 m @ 8.8 g/t AuEq (8.7 g/t Au, 0.1 %Sb) from 835.1 m

 including 1.8 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 minerali zation with thick quartz carbonate veins up to 1 m wide with gold and

arsenic, but no antimony minerali zation. 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 R ajapalot 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 mineraliz ation style wi th 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 mineraliz ation trend and therefore the true thickness of the mineralize d 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) minerali zation. Better gold and

antimony results included:

• 8.5 m @ 2.3 g/t AuEq (1.3 g/t Au, 0.6 %Sb) from 493.5 m

o Including 0.4 m @ 15.9 g/t AuEq (2.5 g/t Au, 8.5 %Sb) from 493.5 m

o 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 minerali zed 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.

Figure 1: Sunday Creek mineralization is changing at depth, with thick quartz-carbonate veins up to 1 m wide with

gold and arsenic, but no antimony mineralization.

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.
