Perth, Sep 30, 2010 (ABN Newswire) - Deep Yellow Limited (
ASX:DYL) (PINK:DYLLF) has completed a review of the November 2007 Mineral Resource estimate for its Tubas Palaeochannel Project in Namibia and is pleased to announce the existing resource estimate by Geomine Consulting Namibia (Geomine) includes a substantial high-grade subset within the total resource, which could warrant a scoping study.
On 21 November 2007 DYL announced the initial Inferred Mineral Resource in accordance with the JORC Code for Tubas totalling 77.3 million tonnes at 0.023% (228 ppm) U3O8 for 17,600 tonnes or 38.8 million pounds contained U3O8 at a cut-off grade of 100 ppm U3O8.
A cut-off grade of 100 ppm U3O8 was selected at the time (November 2007) as the uranium spot price had peaked earlier in 2007 at US$136 per pound U3O8 and was US$90-95 per pound when the Tubas resource was announced. However, given current uranium market prices at US$46-48 per pound, the economics of potential uranium production can be significantly improved with higher average grade as can result from using a higher cut-off grade.
Upon review of the existing resource estimate at Tubas, it was determined that by using a cut-off grade of 200 ppm U3O8, a substantial quantity of resources could be outlined as a subset of the current resource, but at a much higher average grade. At 200 ppm U3O8 cut-off grade, the Inferred Mineral Resource estimate at Tubas totals 22.8 million tonne at 0.046% (455 ppm) U3O8 for 10,369 tonne or 22.9 million pounds contained U3O8.
The quantity of resources in this high-grade subset of the original Mineral Resource estimate at Tubas are sufficient to justify further evaluation to determine if this high-grade resource warrants a scoping study.
In addition, DYL has previously indicated it is actively working on an update of the Mineral Resource estimate for the south-eastern and central sections of the 30-kilometre Tubas-Tumas palaeochannel for completion early in the December quarter 2010.
These additional resources could add to the significance of the Tubas high-grade resource subset outlined above, which is located in the western section of the Tubas-Tumas palaeochannel.
