Project details
Olympia’s Harts Range tenements in the Northern Territory have been identified as being highly prospective for uranium and explotaion of identified areas has commenced. A low level, slow flying helicopter survey has been completed over anomalous zones. The reconnaissance survey used a hand held gamma ray spectrometer (6 cu inch Nal sensor) combined with very low level inspections as necessary. Ground inspections, sampling and reconnaissance drilling are likely to follow.
Several other companies hold tenements for uranium exploration in the Harts Range area. These companies include Newera Uranium Ltd, Red Metal Ltd and Oklo Uranium Ltd.
The uranium potential for the area is considered to be related to the Arunta Metamorphics and Valley-fill type deposits as well as a prominent uranium anomaly in the Eastern portion of the tenement block.
Arunta Metamorphics
The Olympia tenements cover an extensive area of Arunta Metamorphics, which are known to contain two uranium deposits (Napperby-New Well and Nolans Bore) and various uranium occurrences elsewhere in the region. The types of deposit being sought by Olympia are in structurally controlled situations (e.g. vein/fault related including IOCG types) within metamorphic rocks, and possibly disseminated uranium in granitic intrusives. It is expected that there is likely to be a variety of potentially favourable rocks within the Olympia tenements.
Valley-fill Deposits
Alluvial paleochannels of Tertiary age have developed along some of the more mature parts of the main drainage systems of the Arunta Block. These palaeochannels are favourable sites for the development of “roll-front” and calcrete style deposits of uranium. These deposits are likely to be buried and will require careful exploration. There is a prominent uranium anomaly in the eastern portion of the tenement block where a prominent and extensive uranium channel, aero-radiometric anomaly accompanies a strong lineament in the eastern part of the tenement block that warrants exploration.
