MAWSON EXPLORING 9 HIGH GRADE BOULDER FIELDS OVER 12 SQ. KM IN FINLAND

160 boulders with gold grades ranging from 0.1 g/t gold to 3,870 g/t gold, with an average of 74.9 g/t gold and

median of 0.71 g/t gold

Vancouver, Canada – Mawson Resources Limited (“Maws on”) or (the “Company”) (TSX: MAW) (Frankfurt:

MXR) (PINKSHEETS: MWSNF) announces the result of a systematic review of nine prospect areas at the 100% owned

Rajapalot gold project in Finland. These prospect areas we re discovered by the Mawson team as gold-bearing boulder

fields, from which 160 gold mineralized boulders have now been identified within a 12 square kilometre area. The potential

bedrock source of only three of the nine boulder fields have been located by drilling, with the remaining six boulder trains

now planned for follow up exploration.

Key Points:

 A total of 160 boulders and outcrops with >0.1 g/t gold have been discovered within a 4 kilometre by 3 kilometre

area at Rajapalot. Gold grades range from 0.1 g/t gold to 3,870 g/t gold, with an average of 74.9 g/t

gold and median of 0.71 g/t gold. Samples from boulders are grab samples, which are selective by nature and

are unlikely to represent average grades on the property;

 The sources of six of nine gold bearing boulder fields remain to be discovered;

 The sources of three have been discovered by drilling over the last 18 months, these being:

 Palokas (including 10.0 metres @ 11.6 g/t gold from 110.2 metres, Mawson Release Feb 21, 2017)

 Raja (including 27.0 metres @ 3.3 g/t gold from 64.0 metres, Mawson Release May 02, 2017),

 South Palokas (including 8.4 metres @ 4.2 g/t gold from 206.0 metres, Mawson Release March 07, 2016)

 Glacial transport direction, combined with geological features and base of till drill results indicate only a short travel

distance for all mineralized boulders (<250 m). Rock outcrops related to the boulders have been discovered in five

of the boulder fields.

 Discoveries of additional Palokas-style amphibole-tourma line-chlorite-pyrrhotite boulders over the last month

(assays pending for 4 mineralized boulders) at Hirvimaa have defined immediate drill targets in areas that can be

drilled year-round;

 Winter drilling (2017-18) will focus on delineation of additi onal gold mineralization in prospects already identified

by drilling, and follow-up of boulder fields where the primary source of mineralization remains to be discovered.

Mr Hudson, Chairman & CEO states, "With more than 99% of the gold prospective area at Rajapalot covered with a thin

layer of glacial soil, tracing the source of boulders remains a key to further discoveries. The frequency of boulder discovery

at Rajapalot over at least 12 sq km is impressive. Our field teams are regularly making new finds, including the exciting

Palokas-style mineralized boulders at Hirvimaa, that present immediate drill targets. The bedrock source of only three of

nine boulder fields are known to date, with all nine still providing excellent discovery opportunities.

Further discoveries at Rajapalot will come through rigorous exploration practices and a commitment to drilling. Given the

high success rate of drilling during the last winter program where 28% of drill holes (39 out of a total of 137) recorded

greater than 5 g/t-m intersections, we are looking forward to our upcoming programs.”

A summary of sample statistics is shown in Table 1 and description of all boulder fields is shown in Table 2. Samples from

boulders are grab samples, which are selective by nature and are unlikely to represent average grades on the property. A

lower cut-off for reporting of the boulders is 0.1 g/t Au, and the range, mean and median are all reported to give a more

accurate representation of sample variation.

Compilation and re-examination of all the boulder information was conducted for comparison of the drill results of the 2016-

17 winter drilling and base of till (BOT) results with previously held data. The geochemistry, mineral assemblages and the

shape and size of all boulders was reviewed. Company geologists have determined that the grade distribution of boulders

and their spacial association with outcrops and drill results in dicate that the shallowly buried sources are close to the

northwestern edges of the defined boulder fields.

The source of three boulder fields identified in Figure 1 (Pal okas, South Palokas and Raja) have been located. The source

of the largest boulder field, Rumajärvi, remains elusive, bu t as the boulders contain highly anomalous and disseminated

gold with pyrrhotite, this remains a hi gh-priority target for 2017-18 winter drill pr ogram. Geophysical studies, including

distinguishing magnetic pyrrhotite-bearing metasediments from magnetic volcanic rocks is allowing more effective targeting

of boulder sources.

Technical Background

The qualified person for Mawson's Finnish projects, Dr. Nick Cook, President for Mawson and Fellow of the Australasian Institute of Mining

Metallurgy has reviewed and verified the contents of this release.

Boulder samples were assayed between 2012-2015 and transported by Maws on personnel from site to AL S Chemex Ltd's laboratory in

Pitea, Sweden where the samples were prepared and sent to ALS Chemex Ltd's laboratory in Vancouver, Canada to be analyzed by Au-

ICP21, GRA-21, ME-MS41u and ME-MS61u techniques. The QA/QC program of Mawson consisted of the systematic insertion of certified

standards of known gold content, with blanks at the beginning of each batch. In addition, ALS Chemex inserted a number of blanks and

standards into the analytical process.

intersected in early drilling, but

the sulphidic and gold-bearing

22 anomalous boulders spread

boulders are large and angular

(many 50 cm to 1 m

diameter). They are inferred to

be derived from the NW and W

edges of the boulder field.

This boulder field and

Rumajärvi (below) are

characterized by micaceous,

sulphidic and magnetic

boulders. As such, they form

excellent combined magnetic

and IP targets.
