PROGRESS ON PORTAL RESOURCES’ TROPEZÓN URANIUM PROJECT
Portal Resources Ltd. (TSX-V: PDO)is pleased to announce promising results from a mapping, trenching and sampling program on its El Tropezón uranium project in the San Jorge Basin of Chubut Province, Argentina.
Initial prospecting and radiometric surveying on Portal’s El Tropezón claim located in eastern Chubut Province identified an area greater than 2 square kilometers containing anomalous grab samples and spectrometer results within the Paleocene age sandstones and conglomerates of the Salamanca Formation. The uraniferous horizon is mostly covered by recent alluvial sediments but erosion along the northern boundary of the cover has exposed the uraniferous horizon within the underlying Salamanca Formation. A total of 27 hand trenches were excavated and sampled along 1,850 meters of the exposed uraniferous horizon. The trenches were established in locations previously identified as anomalous for uranium by sampling and radiometric surveying. Assay results have been received from thirteen of the 27 trenches and indicate true thickness ranging from 0.2 to 1.5 meters with grades ranging from 26 to 494 ppm uranium. Four of the trenches within 150 meters of the exposed horizon indicated true widths ranging from 0.2 to 0.9 meters with grades ranging from 124 to 494 ppm uranium and averaging 319 ppm uranium with a true thickness of 0.375 meters.
This area is being further evaluated to determine whether it has the potential for hosting a large low-grade uranium deposit. The initial results are encouraging and further work is planned depending upon the remainder of the trenching results.
The San Jorge Basin hosts significant uranium mineralization within lower Cretaceous age sandstones and conglomerates of the Los Adobes Formation and Paleocene age sediments of the Salamanca Formation. Exploration by Comisión Nacional de Energia Atómica (CNEA – the National Atomic Energy Commission of Argentina) in the basin resulted in the discovery of the Cerro Solo uranium deposit, one of the three discoveries of roll-front style uranium deposits located within 25 kilometers hosted by sandstones and conglomerates of the Los Adobes Formation. A 1997 prefeasibility study of the Cerro Solo deposit by Nuclear Assurance Corporation for CNEA concluded that an open pit and underground mining operation would be economically viable, based on mineable reserves averaging 0.3% U3O8 (10.3M lbs recoverable U3O8) and 0.2% molybdenum (3.3 million lbs recoverable molybdenum). N ote that this study is not compliant with NI 43-101.
A description of the Company’s assets including maps and photographs, can be viewed on the company’s website at www.portalresources.net.
Samples collected in the field are delivered to Acme Laboratory in Mendoza, Argentina S.A., a subsidiary of the international laboratory Acme Analytical Laboratories Limited where the samples are prepared and transported to Acme’s laboratory in Vancouver, Canada for analysis. Samples are analyzed for uranium and trace elements by ICP/MS. Mr. Alex Boronowski, P.Geo, British Columbia is the designated Qualified Person in accordance with the guidelines of National Instrument 43-101. Mr. Boronowski is responsible for the program design and quality control of exploration undertaken by the Company in Argentina.
