The Project encompasses twenty-two contiguous exploration and exploitation licenses totalling 46.6km 2. There are multiple mineralised targets over an extensive strike length with intensive copper mineralisation from surface. Only 16km to the northeast of the CCP is the Nueva Unión joint venture between Teck and Newmont. Nueva Unión is currently developing the multi-billion-dollar Relincho and Fortuna (previously called El Morro) deposits. Whilst the CCP currently presents as a copper oxide project with highly soluble copper oxide mineralisation from surface; it also hosts significant sulphide potential as demonstrated in historical drill intercepts that warrant further investigation and follow-up drilling programs. Norfolk is aiming to establish the Carmen Copper Project as a low-cost, highmargin, value-accretive copper heap leaching operation producing copper cathode at the mine gate. The Orroroo Uranium Project comprises three granted exploration licenses, EL6552, EL6814 and EL6948, which together cover 723km2 , located approximately 274km northwest of the capital city of Adelaide, South Australia within 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 Roger River Project comprises two granted exploration licenses, EL20/2020, and EL17/2021, which together cover 74km2, located 410km northwest of the capital city of Hobart, Tasmania. The Project is prospective for gold and copper as indicated by the intense silicification, argillisation and diatreme breccias in close proximity to the Roger River Fault along with carbonate-rich host rocks.
