Uranium mineralisation extended for over 3km at Oban
Ongoing drilling at Curnamona Energy’s Oban prospect, located 120km northwest of Broken Hill, has now confirmed economic grades of uranium mineralisation over at least 3km, hosted by water saturated sands.Curnamona said drilling in the south over the last few days encountered several good intersections, including 5.45m of 0.06% eU3O8 for a grade thickness of 0.35 m% eU3O8 in drillhole CEY 207, and 4.5m of 0.02% eU3O8 for a grade thickness of 0.1 m % eU3O8 in CEY 212. As drilling progresses, the geological model emerging is one of a sinuous sand strandline system fringing a large lake area that lies to the east and north. This is a different style of uranium occurrence to the traditional palaeochannel, but the roll-front oxidation / reduction process still seems to be controlling the distribution of the uranium mineralisation. Such a strand line system can be laterally extensive, as the present drilling is indicating. Curnamona is being guided by the historic mineral drilling databases across the area to determine the likely strandline positions, and has identified many kilometres of potential strike where it can test this concept. Commenting on the latest drilling results, Curnamona Energy Chairman, Dr Bob Johnson said: “The field remains wide open, with untested extensions to the known uranium mineralisation lying to the northeast and south of our current drilling.” “As the results from each drillhole are analysed, we are progressively developing a better understanding of the mineralisation controls that in turn helps our placement of future drillholes and our success rate,” he said. Curnamona is continuing exploration at Oban and also in the Yarramba Palaeochannel.
