NEWS RELEASE JULY 06, 2021

MAWSON DRILLS 15.3 METRES AT 2.2 g/t GOLD AND 2.1% ANTIMONY AT SUNDAY CREEK IN

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 further drill holes (MDDSC013A-15A) from the

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

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

Highlights:

 Diamond drillhole MDDSC015A, the deepest hole drilled to date at the Apollo mine area (Tables 1-3, Figures 1-3)

intersected (lower cut of 0.3 g/t Au cut over 2.0 metre width, with higher grades reported with a 5 g/t Au cut over

1.0 metre):

o 4.6 metres @ 1.6 g/t Au and 0.1% Sb (1.7 g/t AuEQ) from 222 metres; and

o 15.3 metres @ 2.2 g/t Au and 2.1% Sb (4.3 g/t AuEQ) from 231.4 metres

 Including 0.8 metres @ 1.1 g/t Au and 6.8% Sb (7.8 g/t AuEQ) from 232.3 metres

 Including 0.5 metres @ 6.6 g/t Au and 15.3% Sb (21.9 g/t AuEQ) from 238.1 metres

 Including 2.8 metres @ 5.7 g/t Au and 5.5% Sb (11.1 g/t AuEQ) from 241.3 metres

 Including 0.5 metres @ 10.1 g/t Au and 0.7% Sb (10.8 g/t AuEQ) from 245.6 metres

 Diamond drillhole MDDSC013A, the most south-easterly hole at Apollo, intersected (Tables 1-3, Figures 1-3):

o 5.3 metres @ 3.1 g/t Au and 1.1% Sb (4.2 g/t AuEQ) from 111.1 metres

 Including 0.6 metres @ 14.4 g/t Au and 9.6% Sb (24.0 g/t AuEQ) from 111.1 metres

 Including 0.6 metres @ 8.4 g/t Au and 0.01% Sb (8.4 g/t AuEQ) from 113.5 metres

 Eighteen drill holes (MDDSC001-018) for 2,968 metres have been now completed at the Sunday Creek gold project.

Drilling continues;

Michael Hudson, CEO, states: “Our Victorian portfolio continues to successfully deliver at Sunday Creek with the deepest

hole drilled to date intersecting broad mineralization with multiple impressive higher-grade zones including 15.3 metres @

2.2 g/t Au and 2.1% Sb (4.3 g/t AuEQ) located 50 metres down-dip from our closest drill hole. We continue to be impressed

by the continuity of gold mineralization as we drill to depth, as well as the increasing antimony grades. Drilling continues

as we work towards a maiden resource.”

MDDSC015A was drilled 50 metres below Mawson’s previously reported drill h ol e MDDSC012 wh i c h i n ter sec ted 3 6 . 4

metres @ 2.4 g/t Au and 0.4% Sb, 2.8 g/t AuEQ from 177 metres d emonstrating the consistency of mineralization

continuing to depth (Figure 2 and 3). MDDSC013 was drilled 50 metres SE of MDDSC015A and supports the interpretation

that higher grade mineralization dips steeply to the NW. MDDSC014, drilled beneath the central zone, drilled under the

NE plunging enveloping mineralized surface, intersected low-grade mineralization, with a near-surface best result of 1 metre

@ 0.6 g/t Au from 8.2 metres. M DDSC013 and MDDSC015 were abandoned at shallow depths due to hole deviation near

their collars and redrilled as MDDSC013A and MDDSC015A respectively.

Mawson has now completed eighteen drill holes (MDDSC001-018) fo r 2,968 metres at the Sunday Creek gold-antimony

project. Drilling continues and assays from 15 out of the 18 fi nalized holes have been released. Geophysical surveys (3D

induced polarization and ground magnetics) and detailed LiDAR surveys have been completed. A 2,500-point soil sampling

program at Sunday Creek is near completion extending east-northeast from drilling areas to test the 11-kilometre trend of

historic epizonal dyke-hosted mineralization within Mawson’s te nured areas. The integration of the LiDAR, soil sampling

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

At Sunday Creek, historic gold mining occurred between 1880 and 1920 over a greater than 11-kilometre strike length.

Drilling during 1990-2000s focused on shallow, previously mined surface workings, covering an area of 100 metres in width,

800 metres length but, only to 80 metres average depth. As such, the entire field remains open along strike and to depth.

Apollo was the original deepest shaft to 100 metres in the late 1800s in a series of sheeted stibnite-rich veins, predominately

hosted within a zone of felsic dykes and related alteration that broadly controls gold distribution.

Mineralization at Sunday Creek is hosted in late-Silurian to early-Devonian-aged shales and siltstones containing a series of

dykes of felsic-intermediate composition. Gold is concentrated mainly in and around the north dipping and EW to NE-SW

striking felsic dykes and the halo of associated pre-mineralization dyke-related sericite-pyrite alteration. The mineralization

generally lies within brittle multiple sheeted veins and catacl astic zones. Individual NW striking high-grade quartz-stibnite

veins at Apollo and Golden Dyke, and cataclastic zones at Gladys were the focus of historical mining at Sunday Creek. These

zones have been proven to continue to depth by Mawson. Broader vein-hosted and cataclastic mineralization grading less

than 15 g/t gold appears untouched by the historic miners.

Technical and Environmental Background

Tables 1–3 provide collar and assay data. The true thickness of the mineralized interval is interpreted to be approximately 70 % of the

sampled thickness. Gold-only intersections are reported with a lower-cut of 0.5 g/t gold over a 2.5 metre width except on the edge of

calculated intervals where 1 metre @ >2.0 g/t gold was applied. No upper cut-off was applied.

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 fr esh rock. After photographing and logging in Mawson’s core logg ing

facilities in Nagambie, intervals were diamond sawn in half by Mawson personnel. Half core is retained for verification and re ference

purposes. Analytical samples are 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 go ld using the fire assay technique (25 gram charge), followed by

measuring the gold in solution with flame AAS equipment. Samples for multi-element analysis use aqua regia digest and ICP-MS methods.

The QA/QC program of Mawson consists of the systematic insertio n of certified standards of known gold content and blanks withi n

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 the metal equivalent calculation have a reasonable potential to be recovered.

The gold equivalent (AuEQ) was calculated based on commodity prices as 21 March 2021. The 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.
