Norfolk Metals Limited to commence exploration work at its 100% owned Orroroo Uranium Project, located in South Australia, targeting greenfield uranium discoveries in the Walloway Basin. Initial work will comprise a downhole geophysical survey (Spectral Gamma and PFN) across five (5) prioritised historical petroleum wells at Orroroo providing imminent understanding on the uranium prospectivity. All necessary approvals have been received with geophysics contractor scheduled to commence February 2023.

Norfolk owns 100% of 2 Exploration Licences (EL) totalling 659 km2 covering the inferred limits of the Walloway Basin, which together comprise the Orroroo Uranium Project. The Walloway Basin has never been explored for uranium despite being the same age as sediments observed in the Frome Embayment. The Frome Embayment is host to Four Mile, Oban, Beverly and Honeymoon uranium resources.

Historical exploration undertaken by Linc Energy throughout 2009 to 2011 produced results delineating coal. The coal measures are considered a prime reducing environment for the precipitation of uranium mineralisation. Initial work will comprise a downhole geophysical survey (Spectral Gamma and PFN) of historical petroleum wells to better understand the source of the gamma anomalies, and assist in ranking and prioritising targets for drill testing.

Norfolk is to report that field work is scheduled to commence in February 2023 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 Adelaidean 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. NFL has received all necessary approvals and contracted the services of Geosensor Wireline to conduct Spectral Gamma and Prompt Fission Neutron (PFN) surveys across five (5) priority wells at Orroroo. The survey results are expected to provide the Company with an understanding of the potential uranium prospectivity of EL 6552, being the tenement in which all survey wells are located.

The purpose of the geophysical program is two-fold: firstly, the program will provide direct detection of uranium in the host rock environment and determine the source of gamma anomalies in historical Linc Energy wells (e.g. Orroroo target wells 7 and 15). Secondly, step-out wells are prioritised to infill the survey grid to less than 3 kilometer spacing which is considered appropriate in the reconnaissance stage of exploration for defining the surface footprint of known sandstone-hosted uranium deposits. At this spacing, minor downhole intervals of elevated uranium will be highly encouraging and be the impetus for further downhole geophysics and infill drilling.
