Further drilling update

Thor Mining PLC 09 May 2007 THOR MINING PLC FURTHER DRILLING RESULTS FOR MOLYHIL Dated: 9 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 further significant results from the recently completed program of reverse circulation ('RC') drilling at its 100%-owned Molyhil Tungsten-Molybdenum Project ('Molyhil') in the Northern Territory. All results from the recent round of drilling have been received with the exception of drill holes 07MHRC007 and 07MHRC011. The drilling program was completed in March 2007 with 25 RC holes drilled for 2,586m. Further high grade results (see table 1) have now been received from the program of infill RC drilling.

Samples from this program are being sent to an independent laboratory for check assaying due to their high grade nature. The results from this check sampling program will need to be received before the recalculation of the current resource and ultimately the reserve. A total of 16, of the 25 hole program, were designed to focus on the indicated and inferred parts of the Yacht Club resource. Of these 16 holes, 13 holes intersected mineralisation with 9 holes returning assays with a combined MoS2 + WO3 grades in excess of 1%. Should check sampling verify these results, this further confirms the potential to achieve a rapid capital payback as documented in the Molyhil Definitive Feasibility Study.
