HATCHES CREEK SAMPLE RESULTS

Dated: 28 July 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 announces rock chip and grab sample results from our Hatches Creek Project (EL22912 and EL23463) located around 160kms southeast of Tennant Creek in the Northern Territory. 

Exciting results have been received from the 5 main groups of workings. Significantly the average Tungsten grade returned from 174 samples of wolfram - quartz veins was 2.19%, with a strong Cu, Ag and Bi association with average results of 1.92%, 5.36ppm and 0.22% respectively. Details are set out in the attached appendix.

In May a native title access meeting held at Hatches Creek Project approved a rock chip and mapping program, completed to assist with planning of the proposed RC program. A total of 174 rock chip samples were taken over old workings and from abandoned stockpiles associated with the historic mining centre. Mineralised reefs are present in groups. Mining here occurred from 1913 until 1957 and there are numerous reefs within 16 groups of lodes.

A strong gold association was noted at the Pioneer mine area with maximum gold results of up to 7.24 ppm Au and an average of 0.92ppm Au. At Hit and Miss group a number of samples also returned favourable Molybdenum assays peaking at 1.98%.

Commenting on the results, Thor's Chief Executive Officer, Mr John A. Young, said: 'These exciting results have confirmed the prospectivity of this historic area which has not been subject to modern exploration. Drilling targets have been identified and we look forward to starting drilling as soon as possible, subject to availability of appropriate drilling equipment.'

Appendix

Pioneer Mine Area

Significant gold assays were received from the Pioneer workings at the north end of the Wolfram Field, with gold results up to 7.24g/t Au from mullock dumps at the Pioneer Mine. It is also interesting to note that anomalous gold assays were returned from Battery Sands at the mine up to 2.48g/t Au. Visible wolfram was noted in many of the quartz rock chip samples with a number of results >1% W, average of the 27 samples taken returned 1.16% W and 0.3% Bi

Green Diamond Group

At Green Diamond tungsten mineralisation in the Hatches Creek area occurs as narrow quartz veins (up to 1.5m thick and extending up to 200m in individual lenses) hosting exceptionally high grade tungsten as wolframite crystals several centimetres in length. Virtually all veins visited at old prospects and exploration pits had visible wolframite evident. Thirty eight samples were taken returning a average grade of 1.42% W with maximum of 7.22% W.

Significant copper mineralisation was evident at numerous locations also associated with quartz veining occurring as malachite and/or azurite. High grade copper mineralisation was evident at the Green Diamond 

Prospect where quartz vein mullock from deeper parts of the workings exhibited massive sulphide veining containing bornite and chalcopyrite. High concentrations of malachite and azurite were also noted with four sample returning results of >1% Cu

Hit and Miss Group

Results from quartz vein samples at Hit and Miss returned and average grade from 23 samples of 2.9% W, with a maximum of 13.3%. Other than the obvious wolframite mineralisation, significant molybdenite was noted in mullock at the 'Hit & Miss' workings near Chinamans shaft with assays returning up to 1.98%. The workings are associated with one of the largest veins noted to date although numerous other parallel vein sets occur at the prospect. Not tabled here are the anomalous values here for Ag of up to 46pmm and Sn to 0.2%.

Copper Show Group

The 'Copper Show' workings were also located and are worthy of some follow up work as the main lode is easily traceable in later costeans that have been excavated. Along with the ubiquitous wolframite mineralisation the main lode exhibits significant malachite and azurite. The prospect area is relatively flat lying surrounded by hills. Significant potential exists for additional mineralisation under cover between the northern and southern areas of EL22912.

Treasure Group

The Treasure Group workings cover an extensive area that occupies two valleys and the sides of the adjacent hills in the central part of the Hatches Creek Wolfram Field.  The Treasure Group also boasted a general store a generator shed and large living quarters and office the ruins of which are still evident.  Workings extend to the west previously known as 'Next Treasure'.  The results returned consistently high tungsten assays from visible wolframite in quartz veining, the average tungsten grade returned 3.84% W. Only minor copper was noted in hand specimens in this area which is reflected in the assays.
