Location Map of Project & Drilling Target
 

The Norr Döttern contains many drilled, bed rock and boulder samples over an area of six kilometres by 4 kilometres. Prospects include Norr Döttern 1, Västra Kikkejaur, Norr Döttern 2, Tallberg, Sör Döttern, Östra Järntjärnbäcken, Västra Järntjärnbäcken and Tjpsäive.

Sampling encountered high grade uranium oxide ("U3O8") mineralization at the Norr Döttern 1 Project. In 1974 trenching though soil cover to bedrock discovered a uranium mineralized zone that assayed up to 28.2% U3O8 over 0.2 metres with an average grade of 3.5% U3O8 over 3 metres width along the 5 metre long excavation. The project has never been drill tested and the target remains open along strike and down dip.

A new drill discovery at Östra Järntjärnbäcken in the winter of 2008 is considered very encouraging given that this is the first bedrock drilling program carried out at the prospect.

Ownership

The 100 Ha Norr Döttern nr 3 was free pegged by Mawson Sweden AB (a 100% subsidiary of Mawson Resource Ltd).

Mawson has granted a third party, ASX-listed Hodges Resources Ltd, the right to earn up to 51% in the project by funding work program expenditures of US$1 million over 4 years on 4 of Mawson's earlier stage uranium projects (Norr Döttern, Sjaule, Åsnebogruvan and Harrejokk) in Sweden and up to 75% by fully funding any project to successful bankable feasibility.

Location

The Norr Döttern prospect lies in the Arvidsjaur uranium district, in the Norbotten province of Northern Sweden.

History

Norr Döttern was discovered by the Swedish Geological Survey in 1974 using boulder-tracing.

Property Geology

Uranium mineralization in hosted in granitic and felsic volcanic bedrock and is associated with well defined north-south regional structures.

Location of Drill Holes & Other Significant Geological Information
 

Uranium mineralization as exposed at Norr Döttern 1 occurs as uraninite, hosted in fractures and disseminations within felsic volcanics and granitic rocks.

Seven diamond drill holes were completed for a total of 555.85 metres at the Östra Järntjärnbäcken prospect in the winter of 2008. Best results are shown below and a full set of results provided in Table 1:
  • JTB08002:
  • 7.0 metres @ 0.15 % U3O8 from 22 metres;
  • JTB08007:
  • 1.1 metres @ 0.11 % U3O8 from 33 metres;
  • JTB08004:
  • 2.0 metres @ 0.05 % U3O8 from 49 metres.

    The holes were located to test an area containing uranium mineralization in granitic and felsic volcanic bedrock discovered by previous Swedish Geological Survey sampling, and detailed by mapping and geochemical sampling within the last year. The drilling targeted radioactive bedrock, mineralized granite and felsic volcanic outcrop and hammer drill results over an area of approximately 100 x 200 metres.

    Five of the seven drill holes intersected uranium mineralisation. Mineralized zones ranged in width from less than 1 metre up to 25 metres. Broad intervals of lower grade mineralization were characterised by hematite-epidote altered granite with radiation of 50-200 counts per second as measured with a hand held scintillometer. Higher grade intervals were associated with hematite-uranium veined zones with up to 900 counts per second. These higher grade veins were intersected in JTB08002, 004 and 007. It is interpreted that reported drill hole intercepts approximate the true width of mineralization.

    History

    World Nuclear Association Brief on Sweden

    Ten nuclear power reactors provide approximately 50% of its electricity.

    Swedish mining legislation allows exploration for uranium and places no special restriction on mining where the uranium grade is less than 200 ppm or the production is less than 5 kg. When higher uranium grades are present, permitting will follow a process concerning "nuclear technical activity". Such permitting must pass before the Swedish government for decision making.

    Sweden has been an enthusiastic supporter of measures to improve world environmental quality. Among many others, Sweden in 1992 committed itself to stabilise carbon dioxide emissions at 1990 levels by 2000, and this was reaffirmed in Berlin in 1995. The fact that those levels in 1990 were only 60% of 1970's was due to nuclear energy replacing most oil for electricity generation.

    Both the Energy Commission report and that of an independent economist, W.D.Nordhaus, project that a full nuclear phase-out would increase Sweden's carbon dioxide emissions by about 50% above the 1990 level. This is why European Union proposals for 1997 climate change negotiations allowed for a 5% increase in Sweden's emission levels due simply to the proposed Barsebäck reactor closure.

    One problem with closing any reactor is that in the short run the replacement generation or imports would be fossil fuelled. Local back-up capacity is mostly oil-fired, as indicated in the 1996 figures when hydro production was much less than normal.

    Sweden has its nuclear waste management well in hand. A dedicated ship moves the wastes from power plants to repositories. Some low-level waste is disposed of at reactor sites, some is incinerated at Studsvik. A final underground repository for intermediate-level waste (SFR) has been operating near Forsmark since 1988. The CLAB interim repository for spent fuel (treated as high level waste) has been operating since 1985 at Oskarshamn, and its 5000 tonne capacity is being expanded to 8000 tonnes to cater for all the fuel from all the present reactors. The spent fuel is stored under water in an underground rock cavern for some 40 years. It will then be encapsulated in copper and stainless steel canisters for final emplacement packed with bentonite clay in a 500 metre deep repository in granite.

    Conclusion

    The Norr Döttern project has never been drill tested despite grades up to 28.2% U3O8 assayed from surface outcrops. Basement drill testing of the exposed mineralization and the other magnetic lows is required to determine the strike and dip extent.

    A new drill discovery at Östra Järntjärnbäcken in the winter of 2008 is considered very encouraging given that this is the first bedrock drilling program carried out at the prospect.

    The presence of the many mineralized drillholes and bedrock occurrences at the Norr Döttern 1, Västra Kikkejaur, Norr Döttern 2, Tallberg, Sör Döttern, Östra Järntjärnbäcken, Västra Järntjärnbäcken and Tjpsäive prospects indicates the potential scale of the project.
