PROGRESS ON PORTAL RESOURCES’ LA PAMPA URANIUM PROJECT
Portal Resources Ltd. (TSX-V: PDO)is pleased to announce encouraging results obtained during a reconnaissance and property mapping and sampling program on its La Pampa Uranium project in the San Jorge Basin of Chubut Province, Argentina.
Project staff has been increased to two field crews of 2 geologists, with support personnel, to speed up the evaluation of the company’s properties and identify new target areas. As Chubut Province is experiencing one of the harshest winters on record, the severe weather conditions have slowed exploration on the company’s claims in the vicinity of Comisión Nacional de Energia Atómica’s (CNEA – the National Atomic Energy Commission of Argentina) Cerro Solo uranium deposit, one of three discoveries located within 25 kilometers of each other and hosted by sandstones and conglomerates of the lower Cretaceous in age 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 reco verable U3O8) and 0.2% molybdenum (3.3 million lbs recoverable molybdenum).
Due to the extremely cold weather, the focus of the exploration program has been shifted to lower elevations in eastern Chubut Province, where the crews have identified areas underlain by the Puesto Manuel Arce Formation of Upper Cretaceous age, and the Salamanca Formation of Paleocene age, both of which are favourable for hosting uranium mineralization. The Puesto Manuel Arce Formation is a particularly important target as it hosts the Sierra Cuadrada deposit, one of four sandstone hosted deposits discovered by CNEA during their exploration of numerous radiometric anomalies in the San Jorge Basin during the 1960’s and 1970’s.
Initial prospecting results from Portal’s El Tropezón claim, located in eastern Chubut Province, has outlined an area approximately 1.0 by 0.4 kilometers in size with grab values ranging from 36ppm U to the upper detection limit of >2000ppm U ( 0.2% U ) within sandstones and conglomerates of the Puesto Manuel Arce and Salamanca Formations. Portal is conducting more detail surveys over the area of interest.
In another area of eastern Chubut, four fluvial sediment samples collected from the Puesto Manuel Arce Formation containing carbonaceous trash, an important criteria for concentrating uranium during the mineralizing process, assayed 190, 160, 30, <1 ppm uranium. Additional mapping and sampling is being conducted to define the extent of this newly identified mineralized area.
Reconnaissance mapping and sampling are also being conducted in three other target areas underlain by favourable sandstone and conglomerate units of the Puesto Mauel Arce Formation and caliche-type uranium mineralization associated with Tertiary age sediments.
Portal Resources Ltd. was founded in 2004 and is a natural resource company, based in Vancouver and focused on the exploration and development of high potential uranium, gold-silver and copper-gold projects in Argentina and the U.S.A. The company currently controls over 1,200 square miles of mineral rights in three primary project areas. 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. Nordin is responsible for the program design and quality control of exploration undertaken by the Company in Argentina.
