NEWS RELEASE SEPTEMBER 17, 2020

Mawson Completes 3 Holes at Sunday Creek and Commences Drilling at the High-Grade

Redcastle Gold Project in Victoria, Australia

Vancouver, Canada — Mawson Resources Limite d (“Mawson”) or (the “Company”) (TSX:MAW)

(Frankfurt:MXR) (PINKSHEETS: MWSNF) is pleased to provide an update of exploration activities in Australia. Initial

drilling at Sunday Creek has been completed with first results due before the end of the month. The drill rig has moved to

the Redcastle project and a second drill rig will be mobilized to Mawson’s Victorian projects next week. Multiple geophysical

crews are active at the Redcastle gold project.

Key points:

 Three initial drill holes for 345 metres have been completed at the Sunday Creek gold project in the Victorian

Goldfields. The target was high-grade veining with associ ated mineralised halos, typical of epizonal-style gold

mineralization at the Apollo-Golden Dyke prospect.

o First results are expected before month’s end;

 The drill rig has moved to the high-grade Redcastle Gold Project where extremely high gold grades were mined

over a 4.5 x 7 square kilometre area containing over 24 historic mining areas. They include the Welcome Group

of mines that were exploited over 2 kilometres str ike length from 1859–1865, down to a maximum depth of 125

metres and extracted 20,583 oz @ 254.6 g/t gold;

 A second diamond drill rig is expected to be mobilized to Mawson’s Victorian projects next week. A total program

of 5,000 metres is planned for the remainder of 2020 in Victoria; and

 Geophysical surveys are ongoing at the Redcastle gold project with two induced polarization crews and one ground

magnetics crew. Dipole-dipole IP and detailed gravity will al so be undertaken at Redcastle, before crews move to

Sunday Creek to perform gradient IP, 3D IP and ground magnetics over the coming months.

Mr. Hudson, Chairman and CEO, states: “The search for the next high-grade epiz onal gold deposit is well underway. All

hands are on deck as we execute on our drilling and geophysical programs in Australia. We are excited to have completed

the first targeted diamond drill holes through the mineralized zone at Sunday Creek and results will start to flow during late

September.”

At the Sunday Creek gold project the target is high-grade veining with associated mineralized halos, typical of epizonal-

style gold mineralization at the Apollo-Golden Dyke prospect.

 Historic gold mines at Sunday Creek occur over a greater than 11-kilometre trend. Modern drilling at Sunday Creek

has focussed on shallow, previously mined surface workings, to an average of 80 metres depth. Selected historical

drill results include: CRC013: 21 metres @ 4.8 g/t gold from 9 metres including 2 metres @ 28.8 g/t gold

from 15 metres, and VCRC022: 8 metres @ 11.3 g/t gold from 66 metres including 2 metres @ 40.3 g/t gold

from 70 metres;

At Redcastle the depth extensions of four historic vein areas will be diamond drill tested over the next month for the first

time since mining ceased in the last 1890’s. Additionally, geophysical surveys are ongoing at the Redcastle gold project

with 2 induced polarization crews and one ground magnetics crew. Dipole-dipole IP and detailed gravity will also be

undertaken at Redcastle, before crews move onto Sunday Creek to perform gradient IP, 3D IP and ground magnetics over

the coming months

 At Redcastle, extremely high gold grades were mined over a 4.5 x 7 square kilometre area that contains over 24

historic mining areas, They include the Welcome Group of mines that were exploited over 2 kilometres strike

length from 1859–1865, down to a maximum depth of 125 metres and produced 20,583 oz @ 254.6 g/t gold.

Victoria has produced more than 80 million ounces of gold and has seen three booms: the 1850s, early 1900s, and the last

three years. Two different styles of gold mineralization predominate in Victoria. The deep orogenic (“mesozonal”) style and

the shallow orogenic “epizonal” style. The mesozonal style is well represented in the Bendigo and Ballarat regions that are

often represented by huge mineralizing systems containing abundant nuggety gold that are typically extremely difficult to

accurately model in modern resource calculations. Mawson is sharply focused on the high-grade epizonal-style (i.e.

Fosterville-style).

Qualified Person

Michael Hudson (FAusMM), Chairman and CEO for the Company, is a qualified person as defined by National Instrument 43-101 –

Standards of Disclosure or Mineral Projects and has prepared or reviewed the preparation of th e scientific and technical inform ation in

this press release.

None of the drill and trench data have been independently verifi ed by Mawson at this time. The historical data pre-dates the

implementation of NI 43 101 and are quoted for information purposes only. Drilling and trench information from Sunday Creek by CRA

Exploration, Ausminde and Beadell Resources had a variety of assays and check assays reported in historical reports. It is reported that

the primary analysis for gold was completed by fire assay with an atomic adsorption finish by NATA registered laboratories. XRF assays

were used for antimony.
