Valhalla Uranium Deposit

The Valhalla uranium deposit is located 40km north-west of Mount Isa on Mineral Development Licence (MDL) 510 Previous drilling by Queensland Mines Ltd in the 1960’s, and SRA in the 1990’s and 2000’s, established a combined Measured, Indicated and Inferred Resource of 56Mlb of U3O8 grading 0.14%. Substantial widths of high grade uranium mineralisation in albite-carbonate hematite breccias and mylonites as well as altered mafic rocks have been intersected in the drilling at Valhalla. The deposit is hosted within basalts and basaltic sediments of the Eastern Creek Volcanics, trends north–south and is approximately 1,100m in strike length.

In the September 2010 quarter a Mineral Resource estimate conforming to both the JORC (2004) guidelines and the requirements of NI 43-101 was completed for the Valhalla uranium deposit following validation and compilation of drilling data. The estimate covers the main Valhalla deposit as well as the south eastern extension, Valhalla South.

Updated Valhalla Mineral Resource as at September 2010 (at 230ppm U3O8 Cut-off)


. Mt Grade ppm U3O8 Tonnes
Measured Resources 16.02 819 13,116 28.9
Indicated Resources 18.64 840 15,662 34.5
Total Measured + Indicated 34.66 830 28,778 63.4
Inferred Resources 9.1 643 5,824 12.8

(Figures may not add due to rounding)

The Mineral Resource estimation was completed using the same parameters as previous estimations with the dataset derived predominantly from downhole radiometric logging using company owned equipment. The radiometric grades have also been extensively validated against laboratory assays.
