Mawson Drills 0.23% U3O8 Over 8.5 Metres at Klappibacken, Sweden

Doubles Previously Known Thicknesses of Mineralized Zone Up To 129 Metres; and Extends Known Mineralization from Surface down to Depth of 250 Meters

VANCOUVER, April 28 /- Mawson Resources Limited ("Mawson") TSX - MAW; Frankfurt - MRY. Michael Hudson, President & CEO, announces further results from the Company's 21 hole, 4,836 metre winter diamond drill program at the Klappibacken uranium project in Sweden.

Further uranium mineralization was discovered down dip from previously drilled mineralization, including a high grade zone which returned 0.23% U3O8 over 8.5 metres in drill hole KLADD0820. Significantly another drill hole KLADD0818 intersected mineralization over approximately twice the thickness previously known at the project. Without applying a lower cut-off, KLADD0818 intersected 129 metres at 0.04% U3O8 from 134 metres.

New assay results are presented for four diamond drill holes (KLADD0810, KLADD0813, KLADD0818 and KLADD08020). Best results, calculated with a lower cut-off of 0.01% uranium, are shown below. A full list of results from Mawson's drilling at Klappibacken is listed in Table 1.

    -  KLADD0810 : 39.3 metres at 0.06% U3O8 from 180.0m;
    -  KLADD0820 : 8.5 metres at 0.23% U3O8 from 267.0m
    -  KLADD0818 : 29.5 metres at 0.06% U3O8 from 144.6m;
                   including 3.7 metres for 0.19% U3O8 from 145.3m

These new intersections extend mineralization between 50-100 metres down dip from that previously known. Uranium mineralization is now known from surface down to a vertical depth of 250 metres below surface over a strike extent of 150 metres and remains open at depth. A longitudinal section showing the relationship between these results and previous results from the Klappibacken uranium project may be found at http://www.mawsonresources.com/index.php?page=ProjectsKlapLong. Six additional drill holes from the drill program have been sampled but the assays are yet to be received or reported. Drill holes not sampled to date include KLADD0808, KLADD0811, KLADD0812, KLADD0815, KLADD0816 all drilled to test radon cup anomalies within a one kilometre radius of the known mineralized body at Klappibacken. Although these holes intersected tectonic zones with variable fluorite veining they did not host significant uranium mineralization as determined by hand-held scintillometer logging. Drill holes KLADD0822 and KLADD0823 did not contain significant mineralization and were drilled up dip and to the north along strike respectively from the main body. In this area cross faults are interpreted to offset the mineralized body. Summer drill programs will focus on finding potential near surface offsets of the main mineralized body, and testing mineralization to the limit of open pittable depths.

Klappibacken is an intrusive-related uranium deposit, hosted by brecciated and cataclastic granite which is strongly enriched in fluorite or hematite. Uranium mineralization is present within a structural zone, generally greater than thirty metres in width, and locally exceeding 70 metres wide.

Mr Hudson states, "These results continue to expand the mineralized body at Klappibacken and includes hole KLADD0818 which doubled the previously known thicknesses of mineralization up to 129 metres. High grade mineralization has again been discovered, including 0.23% U3O8 over 8.5 metres in drill hole KLADD0820, following on from the 12.1 metres at 0.44% U3O8 as previously reported in KLADD0807. We await the final set of results to begin calculation of an updated resource estimate. Given the positive nature of results to date, the Company will recommence drilling when summer conditions provide suitable access."

The qualified person for the Klappibacken project, Mark Saxon, Director and Vice-President of Exploration for Mawson, and a member of the Australasian Institute of Mining and Metallurgy, has reviewed and verified the contents of this release. Uranium was analyzed by the ME-XRF05 technique by ALS Chemex Ltd's laboratories in Pitea, Sweden and Vancouver, Canada, where duplicates, repeats, blanks and known standards were inserted according to standard industry practice. It is interpreted that reported drill hole intercepts approximate the true width of mineralization.

About the Company: Mawson Resources holds significant uranium resources in the nuclear energy reliant countries of Spain, Sweden and Finland. As the European Union reduces its reliance on carbon-based energy sources, Mawson is well placed as the Company develops its exploration portfolio towards the sustainable production of uranium in the shortest possible time frame.

On behalf of the Board,
