NEWS RELEASE MAY 13, 2019

MAWSON EXPANDS RAJAPALOT PROJECT WITH NEW GOLD-COBALT DISCOVERY AT RUMAJÄRVI,

FINLAND

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

(Frankfurt:MXR) (PINKSHEETS: MWSNF) announces a new drill discovery at the Rumajärvi prospect of shallow gold-

cobalt mineralization located 700 me tres west and 1.1 kilometres south of the Raja and Palokas resource area s

respectively, at the Company’s 100% owned Rajapalot Project in northern Finland. Highlights include PAL0182 which

intersected 7.4 metres @ 4.4 g/t gold equivalent (“AuEq”), 3.4 g/t gold (“Au”) and 597 ppm cobalt (“Co”) from 86.3

metres.

Assay results continue to be received from drill holes that tested both the boundaries of Mineral Resources at the Raja ,

Palokas and South Palokas prospects, and earlier stage prospect areas including the Hut, Terry’s Hammer and Rumajärvi

(Figures 1 and 2). Mawson recently completed 44 holes (PAL0159–PAL0201D1) for 15,059 metres during the 2019 winter

drill season. Results from 6 holes from the Rumajärvi prospect are provided here, with additional results to be reported on

a prospect -by-prospect basis. Twenty-three holes with full assays remain to be reported that were drilled

predominantly down plunge from resource areas . Sulphidic (pyrrhotite -rich) intersection s with visible gold provide

encouraging signs in drill holes PAL0190 and PAL0 191(Raja), PAL0194 (Palokas) and PAL0198 (South Palokas) , where

assays are yet to be received.

"Our exploration success at Rumajärvi provides encouragement of continued growth of the Rajapalot mineral system,"

said Mr. Michael Hudson, Chairman and CEO of Mawson. “ The discovery of these new gold -cobalt zones at Rumajärvi

clearly demonstrate the potential to increase Rajapalot’s gold -cobalt resources . Rajapalot is a significant and strategic

growing gold-cobalt resource already positioned as one of Finland's top three gold resources by grade and contained

ounces and one of a small group of cobalt resou rces in Europe prepared in accordance with NI 43 -101 policy. We still

have over half the winter season drill holes to report, and look forward to sharing results over the coming month .”

The newly discovered gold-cobalt corridor at Rumajärvi lies on the western flank of the mineralized Rajapalot trend and is

indicated with dashed lines in F igures 1 and 2. The resource areas at Rajapalot trend to the north and east of this

discovery within an overall 4 kilometre trend. Rajapalot remains untested to the south, west and north.

The new Rumajärvi corridor is located 700m west and 1 .1 km south of the Raja and Palokas Inferred Mineral Resources

and represents a new drill- defined mineralized area within the best-developed boulder field in Rajapalot where a total of

55 boulders and outcrops with >0.1 g/t gold have been discovered. Gold grades from a 10 hectare area range from 0.1

g/t gold to 3,870 g/t gold, with an average of 184 g/t gold and median of 0. 6 g/t gold . Samples from

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

Results are available from 6 of 9 holes drilled at Rumajärvi over winter (PAL0177, 179, 181, 182, 183 and 184) . Results

from 3 drill holes from Rumajärvi are awaited (PAL0178, 185 and 186) . Better drill holes from this release include

PAL0182 which intersected 7.4 metres @ 4.4 g/t gold equivalent (“AuEq”), 3.4 g/t gold (“Au”) and 597 ppm cobalt

(“Co”) from 86.3 metres. PAL0179, drilled 200 metres to the NE of PAL0182 intersected 4.7 metres @ 1.9 g/t AuEq , 1.0

g/t Au and 578 ppm Co from 6.0 metres and PAL0183 intersected 0.6 metres @ 2.8 g/t AuEq, 2.2 g/t Au and 340 ppm

Co from 142.5 metres.

Geological Discussion

Rumajärvi prospect area is a discovery at its early stages within the Rajapalot project . Drilling at depth at Rajapalot is

driven by electromagnetic geophysics. At Rumajärvi six modelled geophysical conductors (two ground-based TEM and

four airborne VTEMplus) have only been tested by four drill holes. The discovery is a result of systematically following up

boulder trains, geophysical surveys and scout drilling to target further mineralization.

Vein and fracture fill mineralization formed at multiple stratigraphic levels appears to be the main style associated with

Rumajärvi. It is interpreted that drilling may have only intersected “thin” structurally controlled transgressive veins

marginal to a main mineralized position. PAL0182 (7.4 metres @ 4.4 g/t AuEq from 86.3 m) was drilled to intersect an

inferred linear, NNW plunging Au-Co sulphidic intersection down-plunge from earlier hole PAL0037 (19.5 metres @ 1.8 g/t

AuEq, 0.7 g/t Au, 659ppm Co from 20.5 metres). Mineralization commences at the lower intersection of albite -rich rocks

with schists in association with fine -grained muscovite schists. Unlike at Raja where mineralization lies close to the basal

muscovite quartzite marker , mineralization at Rumajärvi is located over 300 metres structurally above this marker

horizon. Drill hole PAL0179 (4.7 metres @ 1.9 g/t AuEq, 1.0 g/t Au and 578 ppm Co from 6.0 metres), commenced in

mineralization at the base of the glacial till overburden in moderately foliated sulphidic breccia comprising pyrrhotite,

pyrite chalcopyrite, sphalerite and galena in a silicate host comprising chlorite, biotite, Mg -Fe amphiboles, albite, quartz

and tourmaline.

Geological interpretation suggest that mineralization may extend more than 300 metr es to the west of current drilling at

Rumajärvi where VTEMplus electromagnetic plates have not been drill tested. Notably, the only t wo holes drilled 320

metres NNW from PAL0182 (PAL0043 (3.0 metres @ 3.0 g/t AuEq , 2.6 g/t Au, 273 ppm Co from 10.6 metres) and

PAL0184 (1.0 metre @ 1.7 g/t AuEq , 1.3 g/t Au, 206 ppm Co from 117.6 metres) have both intersected gold -cobalt

mineralization. The principal undrilled target occurs in the large fold hinge where the sequence inverts from right -way-up

in the north (South Palokas and upper sequence at The Hut) to upside down in the south (Raja and Rumajärvi). The

construction of a 3D model (grade and structure/stratigraphy) to merge w ith geophysics (especially EM) is planned over

the coming months to help target drilling at the end of the year.

Technical and Environmental Background

The gold equivalent ("AuEq") value used in the resource and this press release was calculated using the following formula: AuEq g/t =

Au g/t + (Co ppm/608) with assumed prices of Co $30/lb; and Au $1,250/oz. AuEq varies with gold and cobalt prices. A long-term price

point has been chosen for both commodities to maintain consistency of reporting individual drill holes against the resource dated

December 2018. Approximate spot prices for gold and cobalt are currently $1280/oz and $16/lb respectively.

Assuming a predominant strataboun d control, the true thickness of the mineralized interval is interpreted to be approximately 90% of

the sampled thickness. Quality control duplicates for all holes show good repeatability of gold assays. Intersections are reported with a

lower-cut of 0.5g/t gold or 304ppm Co over 2 metre lower cut, except where indicated. No upper cut-off was applied.

Four diamond drill rigs (K3 & K8) from the Arctic Drilling Company OY (“ADC”), Kati OY (“Kati”) and MK Core Drilling OY (“MK”), all with

water recirculation and drill cuttings collection systems were used for the drill program. Core diameter is NQ2 (50.7 mm). Core

recoveries were excellent and average close to 100% in fresh rock. After photographing and logging in Mawson’s Rovaniemi facilities,

core intervals averaging 1 metre for mineralized samples and 2 m etres for barren samples were cut in half at the Geological Survey of

Finland (GTK) core f acilities in Rovaniemi, Finland . The remaining half core is retained for verification and reference pu rposes.

Analytical samples were transported by Mawson personnel or commercial transport from site to the CRS Minlab Oy facility in Kempele,

Finland. Samples were prepared and analyzed for gold using the PAL1000 technique which involves grinding the sample in steel pots

with abrasive media in the presence of cyanide, followed by measuring the gold in solution with flame AAS equipment. Multi-element

assays, including cobalt are determined using the ICP -MS method (IMS-230) of MS Analytical shipped directly from the CRS Minlab Oy

facility. The QA/QC program of Mawson consists of the systematic insertion of certified standards of k nown gold content, duplicate

samples by quartering the core, and blanks the within interpreted mineralized rock. In addition, CRS and MS Analytical insert blanks

and standards into the analytical process.

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

Mining Metallurgy has reviewed and verified the contents of this release.
