U3O8 Corp. has an extensive land position adjacent to Argentina’s largest known uranium deposits (the Cerro Solo deposit in Chubut province with a historic resource of 10 million pounds at 0.15% U3O8 and the Sierra Pintada deposit in Mendoza Province with a historic resource of 30 million pounds at 0.12% U3O8) presently owned and under development by the National Atomic Energy Commission of Argentina (CNEA). The CNEA has identified these two areas – the Cretaceous San Jorge Basin of Chubut Province and the Sierra Pintada Uranium District in Mendoza Province – as having the country’s best uranium discovery potential.
U3O8 Corp’s most advanced properties in Argentina are in Chubut Province, and contain both surficial uranium and sandstone-hosted uranium targets. Other properties in Chubut, Mendoza, Salta, Catamarca, San Luis and Santa Cruz provinces constitute grassroots prospects, which are being evaluated and prioritized for further exploration.
Surficial uranium – Laguna Salada is the first project in Argentina to add to our mineral resource inventory. The Laguna Salada Project hosts surficial uranium-vanadium that lies within three metres from surface. Metallurgical test results show rapid uranium-vanadium extraction using alkaline leaching in the Guanaco area of the deposit, while acid leach was very effective in the Lago Seco area.
Sandstone-hosted uranium – The Cerro Solo Area target lies adjacent to the State-owned Cerro Solo uranium deposit. Scout drilling has intersected significant sandstone-hosted uranium of 1-2 metres at 0.1-0.2% U3O8 in two bore holes. Target areas will be refined through IP geophysical surveys and further drilling.
