• Assay results received from detailed soil and rock sampling program over Daicos prospect.

• Highest-grade rock chip sample returned a uranium grade of 7.7%.

• New anomalies and encouraging soil results have defined drilling targets for 2008.

• Raw data received from Bundey EM survey confirms a number of large conductive horizons in palaeochanels.

Thor Mining ("Thor" or the "Company") (AIM, ASX: THR) is pleased to announce an update on current exploration activities at its uranium exploration projects in the Northern Territory of Australia.

Thor has conducted 374 soil samples and 24 rock chip samples at the Daicos prospect, part of the Company's Harts Range Project, to follow-up on results received last year indicating a number of pegmatites with a strong uranium/REE association.

Follow-up work has produced some encouraging results, with the main pegmatite identified under cover, and further rock chip sampling confirming earlier high grade assays with a best result of 7.7% U, 13.8% Ta and 8.54% Nb. Other anomalous elements included Dy, Er, Gd, Hf, Ho, Nd, Tb, Th, Y and Zr.

Further reconnaissance sampling at the Haddock and Indiana prospects at the Hart Range Project confirmed that uranium mineralisation associated with an outcropping pegmatite in a shear zone extends in excess of 600 metres along strike. Rock chip assays were returned up to 904.5 ppm U.

At the Bundey River Project, an EM survey (SkyTEM) has now been completed, costing in excess of A$140,000. Interpretation and modelling will be completed by Montana GIS. Modelling of a number of basement conductors for base metal mineralisation will also be completed for all EM datasets.

Commenting on the latest results, Thor Mining's Chief Executive Officer, Mr John Young said: "A number of drilling targets have now been identified and the approval process is underway to drill test the Diacos area during the second quarter of 2008. The information received from this work will also guide the next round of reconnaissance work in the Harts Range area."

Yours faithfully
