Rompas Gold Uranium

Rompas is a new 100% owned gold and uranium and is secured by 95,000 hectares of claim applications. and uranium mineralization has been discovered at surface over an area exceeding. Hundreds of bonanza grade gold and high grade uranium sites have been discovered to date at Rompas over a NNW-SSE trending area 6.5km long by 200m average width.

Highlights of representative channel samples include 0.95m @ 1,424 g/t Au and 1.3 % U, and 2.05m @ 191.3 g/t Au and 0.44 % U. The average width and weighted average of 49 channel samples assayed is 0.43m @ 222.7 g/t Au and 0.6 % U. Mineralized grab samples (254) average 406 g/t Au and 0.74 % U and ranged from 0.001 g/t to 22,723 g/t Au and 0.1 ppm to >15% U. Grab samples are selective by nature and are unlikely to represent average grades on the property.

Rompas can be classified as a U-Au skarn or metasomatitic vein deposit in metasedimentary and igneous bedrock. A detailed map can be downloaded from the following URL: http://www.mawsonresources.com/i/maps/Rompas_PLANFEB22.pdf.


Asento Uranium

As part of the Areva transaction announced on April 30, 2010, Mawson acquired 100% interest in the Asento project, located near to the Rompas area. Tenure consist of 37 claim applications for approximately 3,556 hectares and are considered to be prospective for vein-style, structurally-hosted hydrothermal uranium deposits hosted within Archaen granites



Riutta Uranium

As part of the Areva transaction announced on April 30, 2010, Mawson acquired 100% interest in the Riutta granted claims which are located in south eastern Finland. Tenure comprise 10 claims for approximately 790 hectares. This area is considered prospective for unconformity-style uranium deposits.



Mustamaa Uranium

Uranium at Mustamaa is locally hosted by a breccia unit. The breccia is contained within greater than 500 metre long and up to 40 metre wide apatite bearing dolomite horizon. Better drill intersections include: R13: 55.4m @ 0.03% U₃O₈ from 104m, including 4.1m @ 0.08% U₃O₈ from 120m and R10: 18.1m @ 0.03% U₃O₈ from 65m, including 8.4m @ 0.04% U₃O₈ from 73m.



Nuottijärvi Uranium

The Nuottijärvi uranium project in central Finland is one of that nation's largest known uranium deposits. In Sept 2010, Mawson calculated a NI 43-101 compliant resource of 2.0 million tonnes averaging 0.074% U3O8, using a 0.03% uranium lower cut-off, for 3.27 million lbs. U3O8. Mineralization at Nuottijarvi remains open along strike and at depth. The resource was based on 43 diamond drill holes for 6,679 metres, drilled on a 50-metre-by-50-metre drill pattern and was completed by qualified and independent geologists Mr. John Nebocat of PGS Pacific Geological Services and Mr. Geoffrey Reed of Reed Leyton Consultants. The mineralized body is approximately 40 metres in thickness, extends from surface to a vertical depth of 80 metres, trends over a strike length of more than 400 metres, and remains open along strike and at depth.
