                                 URANIUM UPDATE


Dated: 11 May 2007



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, announces today that air core drilling will
commence on 13 May at its 100% owned Hale River Project ('Hale River').  The
Central Land Council and representatives of the traditional people of the area
were on site on Wednesday 9 May and Thursday 10 May. Thor has today received
verbal approval for approximately 90% of all drilling sites. The Mining
Management Plan for the initial work programme has also been approved by the
Department of Primary Industries Fisheries and Minerals.


The final report on the Hale River Hoist EM interpretation from the Company's
consultants resulted in six prospective areas being identified along south
easterly striking palaeo-channels, with depth to basement estimated between 45m
and 130m. These channels also contain irregular flat conductive carbonaceous
sedimentary units, which are an important component for the localisation of
secondary uranium mineralisation.


Orbit Drilling Pty Ltd have been contracted to complete the 47 hole, 3,000m air
core drilling programme.  Drilling results should be available in approximately
six weeks.


Approvals have also been sought for drilling on the Plenty River Project,
located to the north east of Hale River.
