The survey results indicate the potential for widespread uranium in the gravel plain. The company targeted to find Laguna Salada-type mineralization in which it says uranium occurs in a roughly horizontal layer within a few metres of surface, covered by a layer of soil and/or gravel.

The anomalous area has a same geometry to the shape of the Laguna Salada deposit which covers an area of 37km2.

U3O8 president and CEO Richard Spencer said: "The highly anomalous zone defined by the radon cup survey has a footprint that is significantly larger than the Laguna Salada resource area.

"Alpha radiation is generated from the natural decay of uranium and its detection within the soil layer has proven to be a reliable pathfinder for covered uranium mineralization."

The company plans to extend the radon survey across the remaining gravel plain beyond the Laguna Salada resource area in an exploration program. It will also undertake systematic trenching after anomalous areas for potential resource growth.

U3O8 is a Canadian-based firm advancing sequential development of uranium projects in South America with a focus on low-cost production.
