The most significant drill intercept to date has been delivered early in the 2011 program
7.08 metres at 1,405 ppm eU3O8
Including 0.85 metres at 5,179 ppm eU3O8
A second drill rig has been engaged to accelerate the drilling program
Thundelarra is pleased to report that drilling at the Ngalia Basin has intersected the highest grade and
broadest width of uranium mineralisation from the project to date. Hole TNG061RC, the second hole
drilled in the 2011 program, intersected 7.08 metres of Tertiary paleochannel mineralisation grading
1,405 ppm eU3O8 at a depth of 135 metres below surface. The intercept included 0.85 metres at
5,179 ppm eU3O8.
The current drilling program of 155 holes for 20,160 metres is targeting an extensive paleochannel
system defined by a Tempest airborne electromagnetic survey carried out late last year (ASX 10
February 2011). Drilling in 2010 identified a broad zone of uranium mineralisation within the channel
system at the Afghan Swan prospect. Hole TNG061RC is located 800 metres north of previously
identified mineralisation.
The mineralisation intersected at Afghan Swan is continuing to display characteristics that are
considered favourable for in-situ recovery (ISR) of uranium.
Drilling is progressing well with the daily metreage exceeding budget. However a second drill has
been engaged to further accelerate evaluation of the vast paleochannel system. So far 13 reverse
circulation and 6 mud-rotary holes have been drilled on a 400 metre by 400 metre pattern. Initial
observation and down-hole logging indicates that several holes have intersected anomalous uranium
mineralisation, although none have intersected mineralisation as significant as TNG061RC. Further
processing and compilation of the down-hole logging data is pending.
These broadly spaced reconnaissance drill holes appear to be confirming the location of the paleovalleys
interpreted from the Tempest survey. Closer spaced follow-up drilling will be required to more
precisely define channels within these valleys that host the most concentrated mineralisation.
Equivalent U3O8 grades are being measured using a Mt Sopris down-hole gamma logger that has
been independently calibrated. Readings are taken at 50 millimetre intervals from within the drill rods
for reverse circulation holes and from the open hole for mud-rotary holes. Factors to allow for the
effects of the drill rods are applied in accordance with the equipment manufacturer?s specifications.
All drilling carried out to date is located on exploration licence EL25334, which is wholly owned by
Thundelarra.
