Exploration for possible Beverley - type Tertiary sedimentary uranium deposits associated with the north-western margin of the Mount Babbage Inlier, being undertaken within a small licence area centred approximately 120 km east of Lyndhurst, has comprised a review of previous exploration data, the conduct of reconnaissance geological mapping, acquisition of portion of a fixed-wing airborne magnetic/radiometric/DTM geophysical survey, and afterwards performing an interpretation and modelling of subsurface stratigraphic and structural features based on this survey's data and on some AEM surveys data acquired by earlier explorers. The licensee's interpretation of contemporary surface drainage patterns and of the available radiometric imagery indicates that at present, and by inference extending well back into the Cenozoic and possibly the Mesozoic past, dissolved uranium is being shed into the five JV Project licence areas from the adjacent tectonically uplifted uranium-rich basement rocks of the Mount Babbage and Mount Painter Inliers. Previous exploration drilling is very sparse and localised, and although it indicates the likely presence of significant thicknesses of prospective Eyre Formation fluvial sand beds, it does not spatially constrain their depositional geometry or their redox state. Over the period July-August 2009, a large airborne magnetic, radiometric and digital terrain model survey totalling 18,818 line km was flown across the entire Marree JV Project area at various different flight line spacings (400 m, 100 m and 50 m) by UTS Geophysics, using a nominal sensor height of 30 m above the natural ground surface. The majority of the survey portion acquired within EL 4279 was flown on 100 m line spacing, with a small portion in the north flown on 400 m spacing [ Note: the raw digital data for the complete survey coverage across all five project licences will be released via SARIG after the end of December 2016 ]. Regional field mapping, and a later geophysical interpretation of the new survey data plus previous airborne EM survey data, has indicated the presence of potentially prospective sand and conglomerate layers within the Cretaceous Parabarana Sandstone within EL 4279 and within the adjacent EL 3390. These areas are thought to be prospective for Beverley 4 Mile type deposits that may have formed adjacent to basin margin faults.

Notes: This release to the public of the subject mineral exploration data, namely, company data which was acquired more than 5 years ago, is being done by DMITRE in accord with the provisions of Section 77D of the Mining Act 1971 and Regulation 88 of the Mining Regulations 2011. During October 2008, the subject licence applicant company entered into a Farm-In and Joint Venture Agreement with a Korean consortium comprising the Korean government (KORES), Daewoo International Corporation and LG International Corporation, who wished to jointly explore, drill and develop the Marree Uranium Project. Under the agreement, the Korean participants are entitled to earn up to an aggregate 50% interest in the project by funding AUD$6.2 million in expenditure on the licences within three years.
