LANGTJARN/VINLIDEN (GL NORTH)

Property NewsNovember 5, 2008 Provides an update from work completed during the northern summer at Långtjärn. During the summer field season at Långtjärn, Mawson has:
• Conducted a ground scintillometer survey over an area of 3.3 kilometers by 2 kilometers which identified the size
and strength of uranium anomalism associated with the magnetic trend.
• Discovered six uranium mineralized outcrops areas in an area of 1400 metres by 600 metres where less than 5% of bedrock outcrops through thin soil cover. Spectrometer assays from rocks at these localities above 0.05%
eU3O8 ranged from 0.06% U3O8 to 8.04% U3O8 and averaged 1.48% U3O8.
• At one of the six outcrop areas, 11 channel samples were taken with a rock saw across an area of 16 metres by 8 metres. Samples assayed above 0.08% U3O8 ranged from 0.08% U3O8 to 1.85% U3O8 and averaged 0.75%
U3O8. An application has been submitted to the relevant Swedish authorities to drill test the strongly mineralized
outcrop and its interpreted extensions beneath the glacial soil cover.
• Found historic records from the Swedish Geological Survey (SGU) which describe a uranium mineralized boulder field covering 15 metres by 10 metres where 4 boulders assayed from 6% U3O8 to 31% U3O8. In 1984, the SGU drilled 32 shallow holes into the lowest glacial soil horizon over this boulder field. Assays from these
samples averaged 47ppm U3O8. The uranium anomalous area remains open in all directions and has never been
diamond drill tested. July 7, 2006 Announced final results from a reverse circulation drill program at the Långtjärn gold project. Best results included 6m for 1.30 g/t gold in LGTRC0602 from 17m within a broader interval of 36 m for 0.45g/t Au.
No further work is recommended at Långtjärn. However mineralization at Långtjärn is located within a 6 kilometre long gold anomalous trend that also hosts the Kyrkviken and Duobblonbäcken prospects. May 7, 2006 Released a technical report on the Langtjarn prospect. Recommendations include: 1) Perform reverse circulation drilling along strike from, and on both sides of, the known resource at the southern Långtjärn zone. 2) Modern geochemical methods, such as sampling of "A-horizon" soils, may be an effective tool to define geochemical signatures in glaciated and heavily till covered terrain. Mapping of the soil grid and further boulder train sampling is also suggested. 3) Further sampling of unsampled sections of the existing drill core would be helpful in determining of there are any other modes of mineralization than the obvious quartz-sulphide association.
