• Previous drilling intersected 1 to 4 m thick mineralisation rarely averaging more than
300 ppm U3O8.
• Present drilling is regularly intersecting thicker zones of up to 13 m at much higher grades,
notably:-

As previously announced Deep Yellow’s wholly owned Namibian subsidiary Reptile Uranium
Namibia (Pty) LTD (RUN) is conducting a vertical RC drilling campaign aimed at defining JORC
Standard resources within the 1970’s drilled Tubas prospect of Anglo American. To date 424
holes have been drilled for a total of 10,785 metre.
The uranium mineralisation occurs as recent secondary concentrations of carnotite in gypcrete
from the surface (in places) that quickly grades into aeolian and fluviatile sands. Mineralisation is
typically restricted to a maximum depth of 30 m and historically was reported by Anglo American to
rarely exceed 4 m in thickness and rarely exceed an average of 300 ppm U3O8
over the
mineralised zone.
RUN’s grid drilling has varied from 50 m spacing to 100 m and lately to 200 m spacing as can be
seen on the attached map and is aimed at augmenting the historical data to allow Deep Yellow’s
consultants to determine JORC resources on an ongoing basis which will eventually encompass
the entire 14 by 4 km area of known mineralisation at Tubas. Initial resource numbers are expected
within two months.

It is very encouraging that not only is the RUN drilling returning higher grades on average to those
that Anglo reported in general; but it is also finding much thicker zones of mineralisation (as
depicted above) at much higher grades than Anglo ever reported.

Although downhole radiometric logging is being done on all holes drilled, the Company will not
report equivalent U3O8
values until the disequilibrium factors are statistically proven.

information compiled by Dr Leon Pretorius a Fellow of The Australasian Institute of Mining and Metallurgy. Dr Pretorius
has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to
the activity which he is undertaking to qualify as a Competent Person as defined in the 2004 Edition of the ‘Australasian
