2,794 ppm U3O8 (0.28%)
2,641 ppm U3O8 (0.26%)
1,497 ppm U3O8 (0.15%)
1,473 ppm U3O8 (0.15%)

These results compliment the previously announced results that included selective grab samples of 6.55% U3O8 (5.56% U) and channel samples in trenches of up to 2.7% U3O8 (2.29% U).

Shareholders are urged to read the announcement of the company's farm-in partner, Western Metals Ltd, at www.westernmetals.com.au which includes a number of diagrams which the directors consider important to gain a proper understanding of the conceptual model.

Introduction

The board of Uranium Resources plc ('Uranium Resources') is pleased to announce an exploration update including the assay results from samples collected during the November 2006 field program on the Mtonya Project in Tanzania and an increase in the joint venture land position.

The November field program included the excavation, sampling, and geological mapping of seven trenches. The trenching also included the extension to Trench 1 that was originally excavated in August 2006. At that time, Trench 1 yielded selective grab results of 5.56% U3O8 and channel samples of up to 0.85% U3O8. Trench 2, which is 15 metres from Trench 1, yielded channel samples of 2.29% U3O8.

Radiometric surveys were also completed in November 2006 at the previously identified Henri, Para and Tahbilk anomalies and reconnaissance surveys were conducted over a five kilometre trend to the north east of Henri identifying several new anomalies. The assay results from soil samples collected proximal to these anomalies are included in this report.

Henri Anomaly

The trenching results and detailed radiometrics conducted over the Henri anomaly have confirmed it as a roll front style uranium mineralisation prospect.

Shareholders are urged to read the announcement of the company's farm-in partner, Western Metals Ltd, at www.westernmetals.com.au which includes a number of diagrams which the directors consider important to gain a proper understanding of the conceptual model.

The latest assay results in conjunction with radiometric surveys and geological observation have generated a conceptual target for mineralisation. (The model is shown in diagram 2 of the Western Metals announcement. It is cross section A to A' on diagram 1 of the Western Metals announcement.)

The results from the data locate Trench1 in the core of the roll front which hosts the very high grade assay results seen from this trench (selective grab samples of up to 6.55% U3O8). Trench 6 shows high uranium results (up to 0.14% U3O8) in reduced sandstone which is interpreted to be in advance of the roll front. These results in conjunction with the radiometric results give encouragement that the high grade roll front is located behind Trench 6 and beneath Trench 1.

Samples of reduced sandstone taken from an exposed gully face approximately 50 metres south-east of Trench 6 produced results between 770 and 1,470 ppm U3O8 (0.077% and 0.147% U3O8 respectively). These samples are interpreted to be from a horizon lower than Trench 6 and suggest that mineralisation could be extensive in advance of the roll front.

Results from Trench 8 located a further 150 metres south-east of Trench 6 show oxidised sandstone with elevated uranium content (up to 570 ppm U3O8; 0.057% U3O8). This is interpreted to be a remnant portion of a roll front that may have been eroded away.

The field work on Henri has provided immediate drill targets with radiometric and sampling data identifying an area of approximately 500 metres by 500 metres that requires drilling to determine the location and nature of the high grade roll front mineralisation.

Other Anomalies

Trench samples collected at radiometric anomalies Para (Trenches 9 to 12) and Tahbilk (Trench 13) gave maximum values of 118 ppm U3O8 (0.012%) at Para and 212 ppm U3O8 (0.021%) at Tahbilk. Surface soil grab samples from these areas also gave elevated results with peak values of 153 ppm U3O8 (0.015%) at Para and 370 ppm U3O8 (0.037%) at Tahbilk. These results are well in excess of background (5 ppm U3O8; 0.0005%) indicating they are highly anomalous and Western Metals considers that surface trenching has not exposed the location of the roll front. Reconnaissance drilling will be required to determine the profile through these areas.

Soil grab sampling from several radiometric anomalies along the interpreted mineralised trend have given the following peak results:

These samples have been collected from the surface soils and are in excess of background. All anomalies have surface radiometric responses in excess of 500 counts per second (cps) which is approximately 10 times background. Further investigation is justified on these anomalies based on the assay and scintillometer results.

Grant of Joint Venture Tenements and Further Tenement Applications

The three tenements that form the joint venture with Western Metals (42.5%) and Tanzanian interest (15%) announced on 23rd November 2006 have been granted by the Tanzanian Government. This land package covers 3,774km2 of prospective uranium properties on the Karoo.

The joint venture has also applied for two additional licences subject to government approval. These two licence applications cover 6,225 km2 and are expected to be granted in the next few months. This takes Uranium Resources' uranium exploration tenement interests in Tanzania to 13,865 km2. These latest tenements all show potential for uranium mineralisation based on geology and historic radiometric data.

The joint venture has also acquired a digital data set of the airborne radiometric surveys flown in the 1980s which will assist with initial ground reconnaissance. Evaluation of this data has provided many uranium anomalies. (These anomalies are as shown in Diagram 4 of Western Metals' announcement).

An in country team is being assembled in Tanzania to undertake exploration campaigns in 2007.

Table 1 Assay Results November 2006 Field Program

Samples have been analysed by ICP using laboratory method ME-ICP61s by ALS Chemex laboratory Perth Australia. Certified reference standards and blanks have been included by Western Metals in addition to laboratory control standards.

All results are in U3O8 ppm uranium with analysis method accuracy quoted at + 10 ppm U3O8. Co-ordinates are WGS84 and have been measured by hand held GPS.
