A licence located in the north-eastern Olary Ranges and the abutting south-eastern Lake Frome Plains, which was centred about 90 km north-east of Olary and 16 km north of Mutooroo Siding, was taken in order to assess the potential for it to have economic Honeymoon or Junction Dam style roll front sedimentary uranium mineralisation, or primary vein style uranium deposits of Radium Hill or Crocker Well type. Initial work comprised an office-based review and GIS compliation by Sturt Exploration of available open file magnetic, gravity, DTM and drillhole data, aimed at identifying southwards extensions to the Yarramba Palaeochannel southern main arm which, only 15 km to the north of EL 4174, hosts the major Honeymoon sedimentary uranium deposit. This review found that the local early Tertiary palaeodrainage system probably had its catchment within the same package of uranium-rich Willyama Complex basement rocks as did the inferred source of the Honeymoon mineralisation. A follow-up reconnaissance field visit to the licence area, to inspect the surface geology and regolith features, led Sturt Exploration to think that doing surface geochemical exploration there to find uranium anomalies would not succeed; instead, doing scout rotary mud drilling and downhole geophysical logging along the interpreted palaeochannel seemed a better option. After a full transfer of subject licence ownership to DBL Blues Pty Ltd was approved by the Minister of Mineral and Energy Resources on 22/8/2012, the new licence operator Core Exploration ('Core') undertook its own review of previous exploration work to identify the potential for palaeochannel hosted roll-front uranium mineralisation. Core found that multiple palaeochannel horizons of varying ages and stratigraphic levels may exist in the region, all with the possibility to contain redox-controlled uranium mineralised cells. Upstream portions of the Yarramba Palaeochannel were interpreted to lie within EL 4174. The company decided to evaluate the airborne TEM and magnetic data recently released by Geoscience Australia and PIRSA from their 2010 Frome Embayment regional TEMPEST AEM survey, before planning any on-ground activities. During 2012, Core switched exploration focus to assess the potential of EL 4174 to contain gold mineralisation of the type ocurring at White Dam. No further work took place on the tenement during its fourth and fifth years, due to Core's exploration priorities being directed elsewhere, before the decision was made to surrender tenure.
