ASX Announcement
ASX Code: DYL
31 January 2011
HIGH GRADE INTERCEPTS CONFIRMED AT THE ONGOLO ALASKITE PROJECT
Namibian-focussed advanced stage uranium explorer Deep Yellow Limited (ASX Code: DYL ) is pleased to confirm significant uranium intercepts from its JORC Resource drilling programme at its Ongolo Alaskite Project area in Namibia. DYL’s wholly-owned subsidiary Reptile Uranium Namibia (Pty) Ltd (RUN), which is conducting the programme, received Fusion-XRF chemical assay results for a batch of 430 samples submitted to the Scientific Services Geological Laboratories in Cape Town, South Africa.
Samples are selected for Fusion XRF-chemical assay based on downhole gamma logging results and these assay results have enabled RUN to outline a number of high-grade mineralised zones within a wider area of lower grade alaskite mineralisation. A further batch of 481 samples has been dispatched for assay with results due before the end of February.
Previous widely spaced reconnaissance grid-line drilling outlined an apparent continuous mineralised zone along a 2 kilometre strike length. Infill drilling to JORC Code standards commenced in December 2010 and will continue over the coming months, however only assay results received by midMarch 2011 will be included in the planned initial JORC Code resource due by the end of the first quarter. Five RC rigs and one diamond rig are currently drilling at Ongolo on a 85 x 53 metre grid and approximately half of the mineralised zone has been drilled out to date. A plan of the project’s drilling area is included (Figure 1) whilst additional and more detailed assay results can be found in Table 1.
Highlights from the assay results include:
-
ALAR246 16 metres at 400 ppm U3O8 from 25 metres
-
ALAR246 12 metres at 404 ppm U3O8 from 98 metres ALAR246 15 metres at 498 ppm U3O8 from 120 metres ALAR246 28 metres at 590 ppm U3O8 from 153 metres ALAD3 18 metres at 939 ppm U3O8 from 118 metres ALAR249 41 metres at 496 ppm U3O8 from 164 metres ALAR192 12 metres at 856 ppm U3O8 from 131 metres ALAR188 16 metres at 405 ppm U3O8 from 185 metres ALAR195 9 metres at 881 ppm U3O8 from 133 metres ALAR219 10 metres at 400 ppm U3O8 from 94 metres

Notes: TD is total depth of hole; U3O8 is chemical assay – fusion XRF. GTM is grade thickness metre and is calculated by multiplying the interval (m) x U3O8 (ppm)
- Values of approximately 400 ppm U3O8 are deemed to be significant by DYL in this environment and therefore lower average values are not reported .

Brief Description of the Geology and Mineralisation
Uranium mineralisation at the Ongolo Alaskite Project is hosted by alaskitic granite, which occurs as voluminous masses and sheeted intrusive dykes, within the metasedimentary Khan Formation.
The Khan Formation locally comprises infolded pelitic and calc-silicate gneisses, which are flanked by thick marble units of probable Karibib Formation. Mineralised alaskite, as steeply dipping, sheeted or anastomosing veins, occurs in a northeast trending corridor, adjacent to the Karibib Formation contact.
The Ongolo mineralisation comes to within 20 metres of surface and underlies a broad, flat gently sloping sheetwash plain thinly veneered by gravelly alluvial and aeolian sands. The enclosing rocks are mostly pelitic gneiss with variable but significant pyrite/pyrrhotite content, which may be important if sufficient to be recovered to support locally generated sulphuric acid production. The uranium mineral is primarily uraninite, and where present at grades of greater than 500 ppm, is marked by the presence of significant visible smokey quartz and, frequently, biotite.

Compliance Statement
The information in this report that relates to Exploration Results, Mineral Resources or Ore Reserves is based on 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 Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Dr Pretorius consents to the inclusion in the report of the matters based on his information in the form and context in which it appears.
Where eU3O8 are reported it relates to values attained from radiometrically logging boreholes with Auslog equipment using an A675 slimline gamma ray tool. All probes are calibrated either at the Pelindaba Calibration facility in South Africa or at the Adelaide Calibration facility in South Australia.
Deep Yellow Limited (DYL) is an ASX-listed advanced stage uranium exploration Company with extensive operations in the southern African nation of Namibia and in Australia. It also has a listing on the NSX.
DYL’s primary focus is in Namibia where its operations are conducted by its 100% owned subsidiary Reptile Uranium Namibia (Pty) Ltd (RUN). Its flag ship is the Omahola Project currently under PreFeasibility Study with concurrent resource drill-outs on the high grade Ongolo Alaskite project and on secondary uranium mineralisation in the Tumas-Tubas palaeochannel/fluviatile sheetwash systems.
In Australia the Company is focused on resource delineation of mid to high grade discoveries in the Mount Isa district in Queensland, including the Queens Gift, Conquest, Slance, Eldorado, Thanksgiving, Bambino and Turpentine Prospects. The Company also owns the Napperby Uranium Project and numerous exploration tenements in the Northern Territory.
