ASX Announcement

ASX Code: DYL

13 October 2011

MAIDEN RESOURCE FOR MS7 DEPOSIT IN NAMIBIA

KEY POINTS

  • Maiden JORC Code Inferred Mineral Resource estimate for the MS7 Alaskite Deposit completed by Coffey Mining Pty Ltd (Perth), totalling 2.7 Mt at 400 ppm U3O8 for 2.3 Mlbs U3O8 at a 300 ppm cut-off.

  • Main mineralised zone now extended to 600 metres long and 300 metres wide extending to 200 metres vertical depth.

  • Ongoing drilling is consistently delivering encouraging results with downhole gamma logging indicating high grade intersections which will be confirmed by chemical assay.

  • Omahola Project Resource base increased to 26.8 Mlbs U3O8 at an average grade of 317 ppm U3O8.

  • Resource upgrades for Ongolo and MS7 expected before the end of the year.

Advanced uranium explorer, Deep Yellow Limited (ASX : DYL ) is pleased to announce that Coffey Mining Pty Ltd (Perth) has completed a maiden Mineral Resource estimate for its MS7 Prospect deposit in Namibia. The prospect is located on EPL 3496 which is held 100% by DYL’s wholly-owned Namibian subsidiary, Reptile Uranium Namibia (Pty) Ltd (RUN).

The maiden resource estimate, at 2.7 Mt at 400 ppm U3O8 for 2.3 Mlbs U3O8 at a 300 ppm cut-off, increases the total Omahola Project Resource base to 26.8 Mlbs U3O8 at an average grade of 317 ppm U3O8 (Table 1) and DYL’s Namibian resource base to in excess of 95 Mlbs U3O8 (Appendix 4).

Deep Yellow Managing Director Greg Cochran was pleased with the result, commenting “in less than six months since the discovery of MS7 we have declared a maiden resource for the prospect and also continue to make promising intersections in our ongoing exploration programme. We are looking at this region with growing optimism in recognition of the increasing possibility that Ongolo and MS7 could join up which may enable us to source most of the Omahola project’s initial production from this area. ”

The drillhole database for the estimation consists of 127 RC drill holes totalling 23,584 metres and 2 diamond drillholes totalling 408 metres with drill spacing of 50 metres by 50 metres to 100 metres by 100 metres (Figure 1). The estimate is classified as Inferred as there is still a large amount of chemical assay data outstanding.

Drilling is continuing southwest from Ongolo and at MS7 (Figure 1) testing the potential that the two may ultimately join up with resource upgrades are expected before the end of the year.

Appendix 2 – Background Information on MS7 Resource

As announced on 6 July 2011, the MS7 alaskite discovery was made in May this year. The prospect is located approximately 2 kilometres to the west of the Ongolo deposit (Figure 1), with drilling delivering consistently good results. From regional geology it is believed that the uraniferous alaskites are within the Khan formation and mineralisation usually seems to be concentrated when these alaskites come into contact with the Rossing and Chuos formations, with a marble unit acting as an impermeable layer (Figure 2).

Current drilling is in a uniform direction to the south at 60[o] as the stratigraphy is folded and dips to the north, northeast and northwest. The main mineralised zone extends about 600 metres along the strike and is up to 300 metres wide and is open to depth below 200 metres.

The drillhole database for the estimation consists of 127 RC drill holes totalling 23,584 metres and 2 diamond drillholes totalling 408 metres. The drillholes were typically drilled at 60° towards 180° with a drill spacing of 50 metres by 50 metres to 100 metres by 100 metres. Only RC and diamond drilling and sampling undertaken by RUN were used in the estimate.

The RC samples are collected at 1 metre intervals in mineralised zones into a three tiered splitter to obtain a 2-3 kilogram final sample. Diamond core is quartered with samples taken every metre in mineralisation. Chemical assays are undertaken at Scientific Services in Cape Town, with Setpoint and Bureau Veritas in Johannesburg used for check assays. Downhole gamma data has been used where chemical assays were not available.

The assay data; 1,526 intervals (442 chemical and 1,084 factored gamma – eU3O8), was composited to 2 metres downhole with statistical analyses on the 2 metre composites undertaken. Variography and search neighbourhood analysis were also conducted as an input into grade estimation. A high-grade cut of 1,200 ppm U3O8 or 1,400 ppm U3O8 was applied on a domain by domain basis to the 2 metre composites prior to estimation.

The method used to obtain estimated grades within the mineralised zones for U3O8 was block Ordinary Kriging.

The estimated zones were classified as Inferred as there is still a large amount of chemical assay data outstanding and the interpreted mineralisation is quite complex. Additional drilling is underway in the central portion of the prospect.

Appendix 3 – MS7 Mineral Resource (Extract from Coffey’s Resource Statement)

The Mineral Resource estimate for the MS7 Uranium Project in Namibia has been finalised. An Ordinary Kriged (OK) estimate was undertaken for the MS7 Project located within EPL 3496 (Figure 1), approximately 2 kilometres west of the Ongolo Alaskite deposit and 15 kilometres NNE of the INCA deposit.

The Mineral Resource Statement is tabulated below in Table 2. Figure 3 shows the location of the modelled mineralised zones and the drilling and Figure 4 shows an example section from the MS7 prospect.

Note: Figures have been rounded

Notes for the resource estimation include:

  • The drillhole database in the vicinity of the estimation consists of 127 RC drill holes totalling 23,584 metres and 2 diamond drillholes totalling 408 metres. The drillholes were typically drilled at 60° towards 180° with a drill spacing of 50 metres by 50 metres to 100 metres by 100 metres. Only RC and diamond drilling and sampling undertaken by RUN were used in the estimate.

  • The RC samples are collected at 1 metre intervals in mineralised zones into a three tiered splitter to obtain a 2-3 kilogram final sample. Diamond core is quartered with samples taken every metre in mineralisation. Chemical assays are undertaken at Scientific Services in Cape Town, with Setpoint and Bureau Veritas in Johannesburg used for check assays. Downhole gamma data has been used where chemical assays were not available.

  • Coffey has not reviewed the QAQC in detail. RUN is the responsible entity for the assay database.

  • Density for the resource was based upon the density of the alaskites from the nearby Ongolo Alaskite Prospect.

  • Geology was modelled for marble lithologies and the main alaskite bodies to aid in the mineralisation interpretation.

  • Mineralisation was modelled based upon a nominal 100 ppm U3O8 lower cut-off. The bulk of the mineralisation was encountered in the alaskite lithologies.

  • The topographic surface was defined based upon the surveyed drillhole collars.

  • The assay data; 1,526 intervals (442 chemical and 1,084 factored gamma – eU3O8), was composited to 2 metres downhole with statistical analyses on the 2 metre composites undertaken. Variography and search neighbourhood analysis were also conducted as an input into grade estimation. A high-grade cut of 1,200 ppm U3O8 or 1,400 ppm U3O8 was applied on a domain by domain basis to the 2 metre composites prior to estimation.
