Mega Uranium Ltd.: Extensive Shallow Uranium Mineralization Delineated in Argentina
Mega Uranium Ltd. (TSX: MGA) (“Mega”) is pleased to report on progress in its ongoing investigation of the shallow uranium resource potential of the Laguna Salada tenements of its Patagonia Project in Chubut Province, Argentina – refer to the Mega news releases of September 4 2007 and December 5 2007.
In the Guanaco prospect area, the exploration to date has included 182 shallow trenches and 11 drill holes (to 8-10 meters depth). Of the 145 trenches for which assay results have been received, 117 trenches have delineated an extensive, consistent, flat-lying layer of uranium mineralization within unconsolidated Quaternary pebbly conglomerates, that are either exposed on surface or lying below less than 0.3 meter of soil cover. The mineralized layer averages 1 meter in thickness, contains grades representative of the whole thickness of 40-200 ppm U3O8(1), and has an overall average grade of all samples of 120 ppm U3O8. Mineralization comprises disseminations of carnotite and autunite within the fine-grained sandy matrix of the conglomerates, in association with carbonates and minor gypsum. To date the mineralization has been traced in trenches and drill holes over a 15 km2 area.
In the Lago Seco Prospect area, located four kilometers southwest of Guanaco, 87 trenches and 4 drill holes have delineated a similar horizontal mineralized layer in unconsolidated pebbly conglomerates under 0.2 meter of soil cover. Over a 4.6 km2 area, the mineralization averages 0.7 meter in thickness, and contains grades over the whole thickness of 120-250 ppm U3O8(1), with an overall average of 140 ppm U3O8.
Mega is now assessing the economic viability of this extensive mineralized layer, as it is amenable to low cost mining and beneficiation based on the following favourable characteristics:
– It occurs on surface or at a shallow depth, generally of less than 0.3 meter.
– It is flat-lying and continuous over an extensive area.
– As mineralization is confined to the fine-grained matrix of unconsolidated pebbly conglomerates, it is suitable for beneficiation by a simple screening process.
– In general, samples of the Lago Seco conglomerates consist of 45% by weight of barren pebbles and 55% by weight of mineralized matrix. In the Guanaco area, where the conglomerates typically contain a higher proportion of pebbles, the samples generally comprise 65% of barren pebbles and 35% of mineralized matrix.
Based on the results of the trenches summarized above, Mega estimates that the 15 km2 area of the Guanaco prospect explored to date contains potential for delineating a resource of the order of 5-8 million pounds U3O8 with an average grade of all samples of the order of 100-140 ppm U3O8. The mineralisation is open to the southeast where a 15km2 area of the Quaternary terrace remains to be investigated by trenches. In the Lago Seco prospect, it is estimated that the 4.6 km2 area explored to date contains potential for delineating a resource of the order of 2-3 million pounds U3O8 with an average grade of all samples of the order of 120-160 ppm U3O8, and that additional potential exists in a 6 km2 portion of the Quaternary terrace to the south. In accordance with the NI43-101 guidelines, Mega wishes to state that the potential quantity and grade is conceptual in nature, that there has been insufficient exploration to define a mineral resource, and that it is uncertain if further exploration will result in the target being delineated as a mineral resource.
Further trenching, shallow drilling and beneficiation/processing test work will be conducted over the area in the coming months to delineate a resource and determine its economic viability.
