Drilling carried out by Thundelarra to date, combined with historic drilling by AGIP, is thought to have
tested less than one percent of the paleochannel systems present.



2267 line kilometres of Tempest Airborne EM surveying completed
Extensive paleochannel systems identified
Potential for uranium deposits of substantial scale highlighted
Interpretation of EM results validated by excellent correlation with existing drill data
Thundelarra is pleased to report that a regional airborne electromagnetic Tempest (EM) survey
completed at the Company�s Ngalia Basin Project has identified very extensive paleochannel systems
within the Lower Tertiary sequence of the basin. These paleochannel systems are highly prospective
for uranium mineralisation as evidenced by Thundelarra�s drilling results in 2010.
Some 2,267 line kilometres were flown on line spacings ranging from 320 metres to 5,120 metres,
providing complete coverage of Thundelarra�s 3,300 square kilometres of tenure within the basin. The
Northern Territory government contributed $100,000 towards the cost of the survey through the
Bringing Forward Discovery initiative.
Conductivity plots clearly define the Lower Tertiary paleochannel system that hosts the Afghan Swan
prospect where Thundelarra�s drilling in 2010 identified extensive uranium mineralisation (ASX 28
October 2010). Correlation with the drilling data is superb (see the map and cross-sections over
page).
Overall the Tempest survey has provided outstanding results demonstrating that the Ngalia Basin
paleochannel systems are far more extensive than initially thought, with potential to host uranium
deposits of substantial scale. The paleochannel hosting Afghan Swan can now be traced for over fifty
kilometres. Furthermore, the style of mineralisation observed is considered potentially amenable to in-
situ recovery (ISR), an extraction method which typically delivers significant economic and
environmental benefits.
Drilling carried out by Thundelarra to date, combined with historic drilling by AGIP, is thought to have
tested less than one percent of the paleochannel systems present. The EM results now allow
Thundelarra geologists to directly target paleochannel systems throughout the Project area. Detailed
modelling and analysis of the EM data is continuing in preparation for systematic and extensive drill
testing of the paleochannel systems to commence in 2011.
