Orroroo Uranium Project
The Orroroo Uranium Project is located approximately 274km northwest of the capital city of Adelaide, South Australia. The Project area can be accessed from Adelaide by road via a very well-maintained national highway to Orroroo town, then 10km north-northeast of the township. Access and infrastructure is excellent.
The Project is located in the Walloway Basin, which is an elongate Tertiary Basin approximately 50km long and up to 15km wide. It consists of Tertiary and Quaternary sediments unconformably underlain by Adelaidian basement.
The Walloway basin has no known basement uranium source defined in the nearby ranges and outcrops. The Walloway basin is underlain by granitic basement rocks which could be the source of mobilized uranium.
All the drilling completed by Linc Energy in 2010 comprised downhole surveys. Downhole electric wireline logs comprised gamma ray, caliper, resistivity and high-resolution density logs were completed for each hole from end of hole to surface.
The figure below shows the Orrorou drillholes drilled by Linc energy with anomalous gamma downhole readings that represent potential uranium mineralisation. The highest single gamma anomalies are in wells ORROROO 15P (>900API) and ORROROO 7P3 (>500API).
