Dear Sir / Madam,
URANIUM MINERALISATION EXTENDED FOR OVER 3 KM AT OBAN
Curnamona Energy Limited (Curnamona Energy – ASX : CUY) reports that ongoing
drilling at its Oban prospect, 120 kilometres northwest of Broken Hill, has now
confirmed economic grades of uranium mineralization over at least 3 kilometres,
hosted by water saturated sands.
Drilling in the south over the last few days has encountered several good intersections
including 5.45 metres of 0.06% eU3O8 for a grade thickness of 0.35 m% eU3O8 in
drillhole CEY 207 (see attached downhole log) and 4.5 metres of 0.02% eU3O8 for a
grade thickness of 0.1 m % eU3O8 in CEY 212 (see map for drillhole locations).
As drilling progresses, the geological model emerging is one of a sinuous sand
strandline system fringing a large lake area that lay to the east and north. It is a
different style of uranium occurrence to the traditional palaeochannel, but the rollfront
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 Energy 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 mineralization 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.”
Exploration is continuing both at Oban and also in the Yarramba Palaeochannel.
Yours faithfully
CURNAMONA ENERGY LIMITED
