Drilling Expands Near-Surface Uranium at Tasjo, Sweden

Vancouver, Canada (ots/PRNewswire) - Mawson Resources Limited ("Mawson") TSXv - MAW; Frankfurt - MRY. Michael Hudson, President & CEO, announces results from additional drill holes completed by Mawson at its Kronotorpet uranium - rare earth element (REE) prospect at the Company's Tasjo project in northwestern Sweden. Results are available for a further 19 drill holes (KRODD06020 to KRODD07038) of a 53-drill hole program. Results for these holes plus the first 19 holes released on March 19, 2007 are in the attached table. Uranium was targeted in a mineralized sedimentary horizon from surface to approximately 40 metres vertical depth, across an area 1,100 metres in strike and 250 metres wide. Drilling was performed on a grid of 25 or 50- metre spacing, on sections separated by 100 metres. The aim of the program was to collect sufficient samples to perform metallurgical test work, and to define an initial CIM-compliant resource within the Kronotorpet area. Better results are included below with a full list of results presented in the attached table 1. ------------------------------------------------ Drill Hole From To Width (m) U(3)O(8) (m) (m) ppm ------------------------------------------------ KRODD07020 38.9 45.9 7.0 252 ------------------------------------------------ KRODD07022 55.6 61.7 6.1 262 ------------------------------------------------ KRODD07022 74.8 79.8 5.0 304 ------------------------------------------------ KRODD07024 9.7 14.7 5.0 277 ------------------------------------------------ KRODD07031 7.3 12.0 4.7 229 ------------------------------------------------ KRODD07032 17.0 21.0 4.0 266 ------------------------------------------------ KRODD07026 5.5 9.5 4.0 263 ------------------------------------------------ KRODD07023 94.2 98.3 4.1 247 ------------------------------------------------ KRODD07036 53.0 56.0 3.0 303 ------------------------------------------------ Tasjo is a sedimentary uranium deposit where uranium mineralization is associated with concretions of carbonate-fluorapatite, which constitute up to 20% of the rock. Mass balance calculations indicate that the uranium grade of the fluorapatite is 0.16%. Significant rare earth element mineralization is contained within the uranium bearing sequence, again associated with the carbonate-fluorapatite. Drilled intersections range from 0.03% to 0.12% combined REE and averaged 0.09% combined REE. The dominant REE at Tasjo are yttrium (Y), cerium (Ce), neodymium (Nd), europium (Eu) and ytterbium (Yb). Mawson controls a 40-km strike extent of the uranium-mineralized unit in the Tasjo field. Based on 80 historic drill holes and the report, "Geological Investigations in the Tasjo area in 1963 and 1964" (G. Armands, Swedish Atomic Energy Company) it is estimated that 75 to 150 million tonnes exist at Tasjo, with a grade range of 0.03% to 0.07% uranium oxide (U(3)O(8)), 0.11% to 0.24% REE and 3.75% to 7.5% phosphate (P(2)O(5)). Total contained metal within the field is estimated to be between 104 to 116 million pounds of U(3)O(8), 165,000 to 180,000 tonnes of REE and 5.63 million tonnes of P(2)O(5). This exploration target estimate is based on the aforementioned report. The potential quantity and grade is conceptual in nature, as there has not been sufficient exploration to define the target at this time; and it is uncertain that further exploration would result in the definition of a resource. The magnitude of the exploration target was confirmed in a recent independent NI43-101 technical report by Andrew Browne of Geosynthesis Pty Ltd, the current qualified person at the Jabiluka uranium project in Australia, after a review of Swedish Geological Survey documentation, a field visit and check analysis of core samples. Further information regarding the Tasjo project and the current drilling program may be found at http://www.mawsonresources.com/index.php?page(equal sign)ProjectsTasjo. In addition, after a test program, a ground EM survey commenced at the Tasjo project to map accurately the near-surface host rock to uranium mineralization over a 20-kilometre strike length. Furthermore, a preferred metallurgical consulting group has been identified with extensive uranium and REE processing experience, with which terms of reference for metallurgical research are being discussed. Mr. Hudson stated: "The new drill results from Tasjo continue to demonstrate consistent at or near-surface uranium mineralization. The Company continues to be encouraged by the regularity of grade, the strike extent and the shallow depth of uranium mineralization. Drilling results from the final third of the program will be released as they become available." Uranium was analyzed by the ME-MS81u technique by ALS Chemex Ltd's laboratory in Vancouver, Canada, where duplicates, repeats, blanks and known standards were inserted according to standard industry practice. The qualified person for the Tasjo 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. 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.
