A dispersed group of tenements covering the known and inferred subcrop extent of the Tertiary Yarramba Palaeovalley in the eastern and northern Lake Frome Plains region is being explored by Curnamona Energy, in a search for possible economic sedimentary uranium mineralisation. The targets are substantial areas of amalgamated sheet (?blanket) sands and areas potentially underlain by Eyre Formation palaeochannel sands. Most of the project ground has not previously been explored for uranium because it contains more deeply buried distal fluvial sediments, formed in Tertiary depositional systems covering and bordering much older basement rocks of the Benagerie Ridge, that were largely by-passed by the uranium exploration phase of the late 1960s and early 1970s. However, their prospectivity has lately been recognised on the basis of interpreted modern aeromagnetic, gravity and airborne EM survey data, and is now being tested. Over the period November 2005 to May 2011, Curnamona Energy has drilled 970 rotary mud holes on adjacent exploration licences held by Havilah Resources NL, also targeting the Yarramba Palaeochannel fill and surrounding sheet sands wherein the subsidiary palaeochannels are less well defined. Significant uranium mineralisation was intersected during this work, particularly within blanket sands at the Oban prospect. During the first year of the project, the licensee did no field work because it was busy procuring drilling and other supportive equipment that would be suitable to use for the conditions of very sandy terrain and lack of ready supplies of drilling water. The intent, which was realised by mid-2008, was for the company to own and operate two drill rigs and ancillary equipment including water trucks, downhole pumps and a backhoe and grader. During the second year of the project, Curnamona Energy undertook reconnaissance rotary mud drilling on ELs 3748 and 4218, completing 85 vertical holes for a total penetration of 9071 m in two campaigns. The holes were initially spaced a nominal 400 m apart, but were later closed in to 100 m apart to evaluate places of emerging interest. Each hole was geologically logged and then was geophysically logged using the company's own gamma ray, induction and guard log tools. Limited bottomhole geochemical sampling of pre-Cretaceous bedrock was also done in 7 holes. Encouraging gamma ray log radioactivity responses were recorded from 3 holes drilled on EL4218 (Yalkalpo), with a highest log-interpreted grade-thickness intercept of 0.022 m% eU3O8 recorded in hole CTH022. The company stated that the drilling results had confirmed the effective role of geophysical data and its computer modelling in providing valid interpreted buried palaeochannel locations and conceptual uranium entrapment targets for testing. During the third year of the project, Curnamona Energy undertook reconnaissance rotary mud drilling on ELs 3770 and 4218, completing 78 vertical holes for a total penetration of 7338 m. These holes were more closely spaced than previously, starting at 200 m apart and again closing down to 100 m, or sometimes 50 m apart where thought necessary to best evaluate the geology. Encouraging gamma ray log radioactivity responses were recorded from drillholes on both tenements, with 4 holes showing interpreted mineralisation grade thickness values of greater than the 0.015 m% eU3O8 cut-off chosen for designating significant occurrences. The best result was 0.027 m% eU3O8 recorded in hole CTH080. In other work, a surface radon emanometry survey was performed on EL 3770 Yalkalpo East over three days in late June 2009, when 246 normalised indicative readings of the radioactive gas flux through the soil were made on a 20 m x 20 m sample grid spacing. During the fourth year of the project, Curnamona Energy delayed doing any further drilling while it awaited receiving the results from an airborne TEMPEST EM and magnetic survey being flown for Geoscience Australia over the Frome Embayment. The coverage included 550 line km crossing the subject project area along 50 east-west flight lines. The entire survey was completed in November 2010, and consultants to Curnamona Energy then began assessing the data. During the fifth year of the project, Curnamona Energy’s on ground exploration activities were focused elsewhere while Native Title negotiations were proceeding. During the sixth year of the project, on ground exploration activities were again focused elsewhere with no work completed within the tenement group. During the seventh year of the project, on the 30 April 2012 Havilah Resources NL announced a takeover offer of Curnamona Energy in a bid to acquire 100% ownership. At this time all exploration on Curnamona Energy Tenements was halted, while a review of exploration commitments was undertaken. Subsequent to the successful takeover Havilah pursued joint venture opportunities without a successful outcome, owing to the depressed Uranium market. Havilah continues to believe that the exploration licences are prospective for uranium. Untested sections of the Yarramba Palaeochannel, historic anomalous holes mostly in “blanket sands” areas and areas targeted by the airborne electromagnetic and magnetic survey remain to be tested when the current economic climate improves. During the eighth year of the project, Havilah did not add any new scientific data worth reporting, and as such no technical report was submitted. These tenements were incorporated into the Amalgamated Expenditure Arrangement – Curnamona Project in the Curnamona Craton. During the reporting period exploration within the project area was focused elsewhere.
