                           Uranium Exploration Update



Dated: 3 April 2007



Thor Mining PLC ('Thor' or the 'Company') the specialist metals company
currently focussed on advancing tungsten-molybdenum and uranium projects in the
Northern Territory of Australia, today announced that it had received the final
interpretation from the HoistEM survey completed over its Hale River Uranium
Project ('Hale River').



Highlights



•   A major palaeo-channel identified with numerous connecting subsidiary
    channels has been identified; and

•   Five new targets to be drilled.



Thor is pleased to announce that drilling will commence in April on a number of
targets at Hale River subject to approvals from the DPIFM and the CLC.  The
modelling and interpretation of 200m spaced HoistEM data at Hale River has been
completed which has identified a complex palaeo-channel structure.  In the past
the area has had limited wide spaced drilling coverage which identified
anomalous 'roll front' style mineralisation.



Final interpretations have been received for Hale River.  A 3D basement
topography surface has been created from interpretation of 1D layered earth
inversion modelling of the HoistEM survey data and the locations of conductivity
shells have revealed five major drill targets within a south easterly striking
palaeo-channel and the connecting subsidiary channels.  3D modelling of
conductivity shells is interpreted to indicate the presence of carbonaceous
sediments within the palaeo-channels providing a reducing trap for uranium
bearing groundwater essential for the formation of 'roll front' Uranium
deposits. Zones of conductive and resistive sediments (indicating reducing and
oxidizing environments) have been interpreted within the main and subsidiary
palaeo-channels within the model.  The revised modelling has also incorporated
previous exploration drilling that has already identified anomalous areas of '
roll front style' uranium mineralisation. Target areas identified in the recent
modelling are also coincident with surface radiometric anomalies.



Commenting on the results, Thor's Chief Executive Officer, Mr John A. Young,
said: 'I am very pleased with the results from the HoistEM survey at Hale River.
Drilling programs are now being planned in detail and are scheduled to
commence in late April 2007. Drilling will test a number of priority targets
some of which have all the ingredients for a discovery'
