HIGHLIGHTS
- Increased size and strike length of Henri Anomaly
- 6 further anomalies identified at Henri
- 3 additional anomalies identified at Mtonya Project
- Numerous drill targets now identified at Mtonya
- More high grade uranium results from trench sampling
- Best trench results from channel samples

* For conversion to U3O8 the uranium ppm values should be multiplied by 1.18.
INTRODUCTION
Uranium Resources plc is pleased to advise that the November exploration field program on the Mtonya Uranium Prospect in Tanzania has been successfully completed.
The Company also advises that it has received the final assay results of field work conducted during the August field program in the area.
The work was undertaken by the Company's farm-in partner, Western Metals Ltd (ASX:WMT; www.westernmetals.com.au).
NOVEMBER FIELD PROGRAM
The field program was completed successfully on 2 December 2006 with a further 7 trenches excavated and sampled, bringing the total number of trenches at Mtonya to 13, as well as radiometric surveys completed in detail at Henri. Radiometric surveys were also completed at the previously identified Para and Tabilk anomalies.
Further a field, reconnaissance surveys were conducted over a 5 km trend to the north east of Henri, identifying several new anomalies at Galway, Moysten and Grandfather.
Exploration activities undertaken were:
- Excavating, sampling and geological mapping of a further 7 trenches at the Henri, Para and Tabilk anomalies;
- Detailed radiometric surveys over the Henri anomaly area including extensions to the north and south;
- Increased radiometric survey coverage over the Para and Tabilk anomalies; and
- Reconnaissance radiometric surveys over a further strike extent of 5 kilometres to the north east of Henri.
Uranium Resources director James Pratt said, 'The data collected by Dr Drake-Brockman on the recent field trip further enhances the Company's belief that the Mtonya system has the potential to host a significant ore body and provides the Company with further immediate drill targets for our planned drilling program in June 2007 post the upcoming wet season.'.
The Henri detailed radiometric survey has provided greater definition over the known anomaly and identified a further six >200 cps anomalies within 250 metres of the Henri discovery anomaly.
The surveys of the Para and Tabilk anomalies have increased the extents of the anomalies with trenching completed on these areas to determine the distribution of uranium near surface.
500 cps at surface with some areas exceeding 1000 cps. These results provide targets for further detailed work to determine further drill targets.
The radiometric data in conjunction with the known assay values indicate many drill targets exist in the work area tested to date.
For diagrams of the anomalies, refer to Western Metals announcement on their web site at www.westernmetals.com.au.
FUTURE WORK AT MTONYA
The next phase of exploration to be undertaken at Mtonya will follow the end of the wet season in April/May 2007. Activities to be conducted include:
- Drilling program over identified anomalies; and
- Airborne radiometric survey over tenement area.
AUGUST 2006 FIELD WORK FINAL RESULTS
All results from the August field program have now been received. Initial results from the August field work were reported on 21 November and this report finalises all the results from that exploration program.
Trenching work conducted at Mtonya in August included excavating, sampling and mapping 5 trenches at the Henri anomaly area and collecting surface samples from sites of elevated radiometric response. Trench 6 was excavated during August but not sampled. This work has now been completed in the November field program with results pending.
Trenches were dug to a depth of 1 to 1.5 metres. Channel samples and selective grab samples were collected and the trenches were geologically mapped. Channel samples were collected at 1 to 2 metre intervals along the length of the trenches. Sample lengths were based on geological boundaries and collected perpendicular to the generally sub-horizontal dip of the host geology.
Trench 1 and Trench 2 at the Henri anomaly showed visible yellow secondary uranium mineralisation. Photographs of the project including the visible uranium mineralisation are available shortly on the Western Metals web page www.westernmetals.com.au.
The assays received from the trenches showed high grade uranium was present in Trench 1 and Trench 2 with lower results from Trenches 3, 4 and 5. The results from Trenches 4 and 5 are interpreted to be from beneath the redox boundary front. The assays remain elevated indicating they are within the mineralized system.
Trench 1 and Trench 2 show continuous zones of uranium mineralisation. Of significance is that both trenches remain strongly mineralized at the eastern and western extremities and in the bases of each trench indicating that the mineralisation is more extensive than these exposures.
Samples were also collected from the surface or shallow trenches (<0.3m) in areas where radiometric responses exceeded 200 counts per second (cps) on the other anomalies in the area. Five anomalies were identified over a 2 kilometre strike length of prospective stratigraphy.
The results of these samples indicated elevated uranium often in excess of 100ppm U in all areas indicating the scintillometer anomalies are related to the presence of elevated uranium and warrant further trenching and drilling.

Notes on Table 1:
Samples have been analysed by pressed powder XRF method by SEAMIC laboratory Dar Es Salaam Tanzania. Certified reference standards and blanks have been included by Western Metals in addition to laboratory control standards.
All results are in ppm uranium with analysis method accuracy quoted at + 10 ppm U.
* For conversion to U3O8the uranium ppm values should be multiplied by 1.18.
Co-ordinates are WGS84 and have been measured by hand held GPS.
