URANIUM EXPLORATION UPDATE

Dated: 6 March 2008

Thor Mining PLC ('the Company' or 'Thor'), AIM, ASX: 'THR' the specialist metals
company focused on advancing tungsten-molybdenum and uranium projects in the
Northern Territory of Australia, today releases an update on current exploration
activities on its uranium exploration projects in the Northern Territory of
Australia.


HIGHLIGHTS
     
•    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; and

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


Harts Range Summary

The Harts Range project area lies on the eastern margin of the Entia Dome. The
Entia Gneiss forms the core of the Entia Dome, which is located on the western
part of the Exploration License area. In late July, a mapping and rock chip
survey was carried out on tenements EL24736 and EL24734, two of the tenements
within the Harts Range Uranium Project which is located approximately 200km
east-northeast of Alice Springs in the Arunta Province of the Northern
Territory.


Daicos Prospect

Last quarter reconnaissance rock chip samples and soil samples were taken on
pegmatite veins mapped at the Daicos prospect area. These had previously
returned a best assay of l9.37% U from highly radioactive samples with visible
uraninite and columbite. The rock samples were taken along a number of contact
zones associated with an exposed pegmatite vein system covering an area of 300m
by 400m.

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.

A total of 374 -80 mesh soil samples were collected over a 100m x 50m grid
spacing covering the Daicos prospect area. A further 22 additional rock chip
samples were collected from veining in the area.

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.


Haddock Prospect

Numerous anomalous rock chip sample assays were returned from additional
reconnaissance sampling over the base of the hill in epidote altered
metamorphosed sediments. A best result of 904.5ppm U was returned from the
sampling.


Indiana Prospect

Additional reconnaissance sampling has confirmed that anomalous uranium
mineralisation associated with outcropping pegmatite in a shear zone extends in
excess of 600 metres in strike length. Anomalous rock chip assays were returned
up to 781.3 ppm U.


Rock Chip Results

A total of 99 additional reconnaissance rock chip samples were collected in
October/November 2007 over the Daicos, Haddock and Indiana prospects.



Bundey River Project

The airborne EM survey (SkyTEM) was completed in January costing in excess of
AUDS$140,000. Initial height corrected field data indicates the presence of
conductors within the palaeo drainage system on the eastern side of the
tenement.

Interpretation and modeling will be completed by Montana GIS. Modeling 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.'
