Encouraging Uranium Sample Results in the Patagonia Project, Argentina

May 9, 2007
  • Results indicate significant potential for several shallow horizons of uranium mineralisation in the Sierra Cuadrada and Mirasol prospect areas
  • Chip sample results of the mineralized horizons include 1 metre @ 1.89% U3O8, 0.5 metre @ 1.5% U3O8, 0.4 metre @ 1.18% U3O8 and 1 metre@ 0.6 % U3O8

Toronto, Canada, May 9, 2007 – Mega Uranium Ltd. (MGA-TSX) ("Mega") is pleased to announce encouraging exploration results in its Patagonia Project in the San Jorge Gulf Basin of Chubut Province, Argentina. In its Sierra Cuadrada and Mirasol concession areas, ground radiometric surveys, geological mapping and rock chip sampling have delineated several stratiform mineralized horizons containing significant uranium mineralisation over extensive areas in the lower part of the Cretaceous Chubut Group. The mineralized horizons occur within the stratigraphic package that hosts the Cerro Solo deposit, held by the National Atomic Energy Commission of Argentina (CNEA), which is reported to contain a resource of 10.3 million pounds U3O8 at an average grade of 0.3% U3O8 and a substantial 0.3% molybdenum credit.

In the Sierra Cuadrada prospect area, located some 140 kilometres southeast of the Cerro Solo uranium resource, a total of 217 reconnaissance chip samples* were collected from exposures of two 0.5-1.5 metre thick mineralised horizons hosted within a 20-30 metre thickness of volcaniclastic sediments in the lower part of the Chubut Group. Samples of the flat to very shallow-dipping mineralized horizons were taken from sporadic outcrops in gullies over an 8 kilometre (E-W) X 3-5 kilometre (N-S) area. Of the 217 samples taken, 103 returned assay values > 100 ppm U3O8 and 14 returned values > 0.2% U3O8.

The largest concentrations of the higher assay results in the Sierra Cuadrada area are in the Cerro del Medio, Quebrada Seca and Cerro Chato sectors. In the Cerro del Medio area, 20 of a total of 24 samples taken from two stratigraphically separate mineralized horizons within a 0.4 km2 area returned values >200 ppm U3O8, the highest being 1 metre @ 0.6% U3O8 and 1 metre @ 1.89% U3O8. In the Quebrada Seca sector, 10 of 27 samples taken from a single 0.5-1.5 metre thick mineralized layer returned values >200ppm U3O8. In the Cerro Chato sector, 114 chip samples were taken from a single mineralized layer along an 8 kilometre long east-west zone. Of these, 36 returned values >500 ppm U3O8, the best results being 0.5 metre @ 1.5% U3O8, 0.4 metre @ 1.18% U3O8, 1 metre @ 0.5% U3O8 and 1 metre @ 0.6% U3O8. Based on the results obtained to date, there is potential in the Sierra Cuadrada area for an extensive area of these mineralized horizons under ~25 metres of cover. There has been no previous drill testing of this area.

In the Mirasol prospect area, some 70 kilometres east of Cerro Solo, a programme of reconnaissance geological mapping and rock chip sampling was undertaken to investigate radiometric anomalies delineated by a CNEA airborne survey in the 1970s. The mapping outlined significant uranium mineralisation within three 0.5-2 metre thick horizons in a very shallow dipping (~4o east), 20 metre thick portion of the Lower Chubut Group, consisting of tuffs and fine conglomerates with abundant carbonaceous material. Of an initial 46 chip samples taken from widespread exposures of the mineralized horizons in gullies, 10 returned values > 200 ppm U3O8, the best being 0.9 metres @ 0.41% U3O8 and 1 metre @ 0.12% U3O8.

Interpretation of the Mirasol results to date indicate that the prospective stratigraphy that hosts the mineralized horizons is present under <30 metres of overlying younger sediments over an extensive area of some 8 km2. There has been no previous drilling in this area.

*All chip samples referred to in this release were collected from channels transecting bedding at a 90o angle and are thus representative of the true width of the mineralized horizons.
