NEWS RELEASE DECEMBER 13, 2021

MAWSON DRILLS 3.0 m @ 41.4 g/t GOLD AND 12.0 % ANTIMONY WITHIN 11.7m @ 12.4 g/t

GOLD AND 3.6 % ANTIMONY IN DEEPEST HOLE AT SUNDAY CREEK, VICTORIA, AUSTRALIA

Vancouver, Canada — Mawson Gold Limited (“Mawson” or the “Compa n y ” ) ( T S X : M A W ) ( F r a n k f u r t : M X R )

(PINKSHEETS: MWSNF) is pleased to announce assay results from three diamond drill h oles (MDDSC023-25) drilled at

the 100%-owned Sunday Creek project in the Victorian Goldfields of Australia. The Sunday Creek epizonal-style gold project

is located 56 kilometres north of Melbourne and within 19,365 hectares of granted exploration tenements.

Highlights:

 11.7 metres @ 12.4 g/t Au and 3.6 % Sb (16.0 g/t AuEq) from 362.0 metres in hole MDDSC025,

including:

o 3.0 metres @ 41.4 g/t Au and 12.0 % Sb (53.4 g/t AuEq) from 364.0 metres;

o 0.5 metres @ 14.3 g/t Au and 4.4 % Sb (18.7 g/t AuEq) from 370.8 metres;

 MDDSC025 is the deepest drill hole drilled at Sunday Creek (320 metres vertical depth), and highest-grade gold-

stibnite mineralization to date on the project (Tables 1-3, Figures 1-3)

 The proposed spin-out of Mawson’s Australian assets onto the Australian Stock Exchange (“ASX”) is progressing

well, with Mawson recently receiving ASX’s positive reply for Southern Cross Gold’s In-principle Advice submission

to support Southern Cross Gold’s suitability for admission to t he official list of the ASX. Southern Cross Gold is

now moving to the pre-IPO private placement financing stage to fund continued exploration, drilling, working

capital and IPO expenses in Australia.

Michael Hudson, Executive Chairman, states: “Sunday Creek is one of the best discoveries to be made in the

modern renaissance of the Victorian goldfields. With bolder and larger step-outs the project continues to

deliver. Our deepest hole at the project to date has intersected the highest grades and widths we have seen.

This is the eighth intersection exceeding 100 “grade (g/t) x wi dth (m)” on the project. Mineralization

remains open at depth and the system continues 10 kilometres to the east covering historic mines, without

a single drill hole test.”

MDDSC025 is a large step-out, located 380 metres east of MDDSC021 (Figure 1), the previous deepest intersection drilled

at the project (21.7 metres @ 4.7 g/t Au and 1.0 % Sb (5.6 g/t AuEq from 274.7 metres) (Figure 2). MDDSC025 (Figure 3)

intersected:

 11.7 metres @ 12.4 g/t Au and 3.6 % Sb (16.0 g/t AuEq) from 362.0 metres in hole MDDSC025, including:

o 3.0 metres @ 41.4 g/t Au and 12.0 % Sb (53.4 g/t AuEq) from 364.0 metres or 6.5 metres @

20.6 g/t Au and 6.0 % Sb (26.6 g/t AuEq) from 362.5 metres;

o 0.5 metres @ 14.3 g/t Au and 4.4 % Sb (18.7 g/t AuEq) from 370.8 metres;

MDDSC024 metres at Gladys, drilled 180 metres SW of MDDSC025 intersected:

o 5.0 metres @ 1.1 g/t Au and 0.3 % Sb (1.5 g/t AuEq) from 195.0 metres;

MDDSC022 at Rising Sun and MDDSC023 at Gladys did not intersect significant mineralization (Figure 1).

Mawson has now completed twenty-six drill holes (MDDSC001-026) for 6,447.8 metres at the Sunday Creek gold-antimony

project since mid-2021 (Figures 1 and 2). Assays from 25 out of the 26 finalized holes have been released. The drill rig will

return to Sunday Creek in January 2022 after completing two dia mond drill holes at the Whroo JV project. Geophysical

surveys (3D induced polarization and ground magnetics) and deta iled LiDAR surveys have been completed. Mawson has

also completed a 1,200-point soil sampling program at Sunday Creek extending east-northeast from the drilling area to test

the 11-kilometre trend of historically mined epizonal dyke-host ed mineralization within Mawson’s tenured areas. The

integration of the LiDAR, soil sampling data, rock chips and geophysics is key to the expansion of the project along strike.

The previously announced spin-out Mawson’s Australian assets into a new entity, Southern Cross Gold Pty Ltd. ("Southern

Cross Gold") via an Initial Public Offering (“IPO”) for admission to the official list of ASX Limited (“ASX” or “Australian Stock

Exchange”) is progressing well. ASX’s positive reply has now be en received for Southern Cross Gold’s In-principle Advice

submission to support Southern Cross Gold’s suitability for admission to the official list of the ASX. Southern Cross Gold will

now move to the pre-IPO private placement financing stage to fund continued exploration, drilling, working capital and IPO

expenses in Australia from sophisticated and professional (“accredited”) investors.

Technical and Environmental Background: Tables 1–3 provide collar and assay data. The true thickness of the mineralized interval

is interpreted to be approximately 60 % of the sampled thicknes s. All drill results quoted have a lower cut of 0.3 g/t Au cut over a 2.0

metre width, with higher grades reported with a 5 g/t Au cut over 1.0 metre applied unless otherwise stated. Lab duplicates and quarter

core field duplicates demonstrate that mineralization is homogenous with a low nugget effect evident. A diamond drill rig from contractor

Starwest Pty Ltd was used in the program. Core diameter is HQ ( 63.5 mm) and oriented with excellent core recoveries averaging close

to 100% in both oxidized and fresh rock. After photographing and logging in Mawson’s core logging facilities in Nagambie, intervals were

d i a m o n d s a w n i n h a l f b y M a w s o n p e r s o n n e l . H a l f c o r e i s r e t a i n e d for verification and reference purposes. Analytical samples ar e

transported to On Site Laboratory Services’ Bendigo facility which operates under both an ISO 9001 and NATA quality systems. Samples

were prepared and analyzed for gold using the fire assay techni que (PE01S method; 25 gram charge), followed by measuring the g old

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 Mawson consists of the systematic insertion of certified standards of known gold

content, quarter core duplicates and blanks within interpreted mineralized rock. In addition, On Site inserts blanks and standards into the

analytical process.

Gold Equivalent Calculation: It is the opinion of Mawson that all the elements included in t he metal equivalent calculation have a

reasonable potential to be recov ered. The gold equivalent (AuEq ) was calculated based on commodity prices as 21 March 2021. Th e

AuEq formula is as follows: AuEq(g/t) = (Aug/t) + (XX * Sb%), where XX = (US$5,600/100) / (US$1,750/31.1035) and the gold price =

US$1,750/oz and antimony price = US$5,600/tonne.

Qualified Person: Dr Nick Cook (FAusMM), Chief Geologist for the Company, is a qu alified person as defined by National Instrument

43-101 – Standards of Disclosure or Mineral Projects and has pr e p a r e d o r r e v i e w e d t h e p r e p a r a t i o n o f t h e s c i e n t i f i c a n d t e c h n ical

information in this press release.
