Geologically similar to the Athabasca
U3O8 Corp’s exploration model in the Roraima Basin is based on its geological similarity to the prolific Athabasca Basin in Saskatchewan, Canada, and the possibility that the Roraima Basin may host unconformity-related deposits similar to the world-class Cigar Lake and McArthur River mines.
We are seeing key geological and chemical characteristics in our Roraima targets that are commonly associated with Athabasca-type deposits. We are refining and ranking our unconformity targets and expect to start scout drilling the most promising areas in 2010.
Through the analysis of archived core drilled by a gold company in the mid-1990’s, integrated with our airborne geophysical data, U3O8 Corp. has defined targets in the Roraima Basin that share many of the features with unconformity-related uranium systems in the Athabasca including:
Structure: The targets lie near the intersection of faults;
Alteration minerals: Sudoite and illite have been detected in archived core. These clay minerals are typically arranged in zones around Athabasca-type deposits; and
Metal enrichment: The archived core contains some elevated uranium values which, importantly, occur with a suite of chemical elements that are commonly associated with uranium deposits in the Athabasca.
