Mawson Resources Limited ("Mawson") or (the "Company") reports on drill results from the recent shallow diamond drill program at the Hirvimaa gold prospect, at Rajapalot in Northern Finland.
Key points:
- Best results returned from the shallow diamond drill program included 0.6 metres @ 21.3 g/t gold and 0.8 metres @ 13.1 g/t gold, from a large mineralized boulder.
- Boulders have the same mineralization style as the Palokas prospect, where recent drill results included 19.5 metres @ 7.4 g/t gold from 1.3 metres (see Mawson Press Releases October 03, 2013, October 16, 2013 and January 20, 2014. The bedrock source for the gold-bearing boulders remains to be identified (Figure 1).
- The shallow drill program also defined a 600 metre long mineralized trend, defined by lower tenor gold anomalism in bedrock, with the best result being 1 metre @ 0.12 g/t gold (Figure 1);
- Drilling continues at Rajapalot with the diamond drill rig moved to the Raja prospect to test recently discovered outcrops (Figure 1).

Michael Hudson, President & CEO, states, "We are very encouraged to have identified and drilled into high-grade, gold-bearing boulders with the same Palokas-style mineralization at Hirvimaa. The source of the boulders is to the north-west of the drilled area, which indicates the mineralized system is more extensive than we have discovered to date. We have unfinished business in this area, however with the field team's very recent discovery of new surface targets at the Raja project, a decision has been made to rapidly mobilize the drill rig to help map and define this new area."
In total, 120 drill holes were completed by independent drilling contractor Ludvika BorrTeknik AB, within an area of 2.5 kilometres by 0.5 kilometres. The average depth of each drill hole was 7.3 metres and the average thickness of glacial soil overburden was 3.9 metres. An additional in-house diamond drill rig with capability to drill deeper was mobilized at the end of the program to complete 16 holes for 116.65 metres. The boulders that were drilled are large (average 0.85m3), angular and considered to be locally sourced from their original position. They were drilled to test initial interpretations which suggested the boulders may have been in-situ sub-crop, however drilling confirmed otherwise.
Geological interpretation of the drill core from this program has provided a better understanding of the host rocks to the Palokas-style mineralization. The disseminated sulphidic, gold mineralized rocks at Palokas prospect are hosted within a sequence of relatively oxidized albite-altered platform calcitic and dolomitic carbonates interbedded with quartz sandstones. It is these host rocks that have been identified in the boulders drilled at Hirvimaa. New interpretation of project-scale airborne geophysics combined with the additional geologic knowledge derived from the Hirvimaa prospect, has led to the identification of the mineralized host sequence in the Raja area, to the southeast of Palokas.
The 2014 summer exploration program has now commenced, with twelve geologists at site. Main field activities will include diamond drilling, surface geophysics, geological mapping and further prospecting work. Further details will be released soon.

Technical Background
The drilling was undertaken by Ludvika BorrTeknik AB of Sweden who provided 32 millimetre diameter core and Mawson's in-house diamond drill rig which provided 25 millimetre diameter core. Drill recoveries were excellent and average close to 100% in fresh rock. Drill intersections are estimated to be 70 to 90 per cent of the true width, except drilling into boulders where true thickness is unknown. After photographing and logging, core intervals averaging one metre in length were cut in half at the Geological Survey of Finland core facilities in Rovaniemi, Finland. These half core one metre samples weigh from 1.5 to 2 kilograms. The samples were then transported by commercial couriers to ALS 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, PGM-ICP27 and ME-MS61u techniques. The QA/QC program of Mawson consists of the systematic insertion of certified standards of known gold content, with blanks at the beginning of each batch. In addition, ALS Chemex inserts a number of blanks and standards into the analytical process. The remaining half core is retained on site for verification and reference purposes. The qualified person for Mawson's Finnish projects, Mr Michael Hudson, President & CEO for Mawson and Fellow of the Australasian Institute of Mining Metallurgy has reviewed and verified the contents of this release.
