Norfolk reported that field work is scheduled to commence at the Orroroo Uranium Project, located in South Australia. The Orroroo Project area 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 Orroroo Uranium Project comprises two granted EL's, 6552 and 6814, covering 659km2 of the inferred limit of the Walloway Basin. The Walloway Basin has previously been explored for coal with Linc Energy having completed a drill program (2009-2011) in which the Walloway Coal seam was discovered. Drilling also identified multiple gamma anomalies which are typical of the "oxidized tails" and "interface zones" of roll-front uranium mineralisation.

The presence of the Walloway coal measure, considered to be a prime-reducing environment for the precipitation of uranium mineralisation, as well as the gamma anomalies identified within previous Linc Energy drillholes presents the Orroroo Project as prime area for sandstone-hosted uranium discoveries. The company plans to investigate gamma anomalies detected by Linc Energy while drilling for coal. Investigations will involve a Spectral Gamma and Prompt Fission Neutron (PFN) downhole tool which will determine the source of the radioactivity.

Roll-front uranium deposits are zoned horizontal tabular bodies which have typical gamma-anomaly signatures dependent on the location within the system. This relationship is shown schematically. Gamma anomalies observed in open-file reports for historic Linc Energy wells are typical of "oxidised tails" and zones marginal to roll-front mineralisation.
