August 2006 Field Work Initial Results Identify Uranium Mineralisation
HIGHLIGHTS
- Trenches show visible uranium mineralisation
- Best assay results include the following visibly mineralised selective grab samples;
- 55,600ppm (5.56%)U*
- 35,880ppm (3.59%)U*
- 18,800ppm (1.88%)U*
- Five ground radiometric anomalies identified over 2 km strike
- Airborne radiometric anomalies along 7 km trend
- Field work has commenced to further evaluate project area
*All results are in ppm uranium with analysis method accuracy quoted at +/- 100 ppm U. For conversion to U3O8 the uranium ppm values should be multiplied by 1.18.
Summary
The Board of Uranium Resources is pleased to announce the initial results of field work conducted on the Mtonya Uranium Prospect in Tanzania by its farm-in partner, Western Metals Limited (ASX:WMT, www.westernmetals.com.au). Under the farm in agreement Western Metals will earn 40% after spending A$2m and can earn a further 20% by spending a further A$2m.
These initial results are the first 53 assays from a total of 100 collected at the Mtonya Project in August. The remainder of the results will be announced when they have been received and verified.
Western Metals' Managing Director George Bauk said, 'These results are highly encouraging and provide the company with walk up drill targets. These results cover 2km of the 7km trend previously identified by airborne radiometric surveys and we are optimistic that more targets will be found. We have a field crew on the ground at the moment extending our data set on this area. This field work will cover approximately 50 km2 of the total 2,500 km2 in the Mtonya Project'.
The Mtonya Project
The Mtonya Project area is in southern Tanzania. Previous field checking of an airborne radiometric anomaly gave a surface spot assay of 980ppm U3O8. This anomaly was subsequently named the Henri Anomaly.
Western Metals conducted field work in August 2006 to evaluate the Henri Anomaly in more detail. A field crew spent two weeks conducting ground based radiometric surveys, trench sampling, geological mapping and surface sampling.
The ground radiometric surveys identified five anomalous areas of radioactivity within an area of 2 kilometers length and a width, at surface, ranging from 100 to 300 metres. The anomalous trend defined by historic airborne radiometric survey extends over 7 kilometres. Field work to date has focused on only 2 kilometres of this trend.
At the Henri Anomaly, interpretation of the radiometric data indicates the existence of three sub-horizontal anomalous layers each separated by approximately 8 vertical metres. Approximately 25 vertical metres of the sedimentary section has been surveyed so far via mapping and trenching of exposed ridges. Drilling will be required to test the anomalies to depth.
Trenching was conducted on several of the anomalous areas at Henri with six trenches dug to approximately 1.25 metres depth. Two of the trenches exposed visible uranium mineralisation in sub-horizontal bands within a sandstone host.
The discrete visibly mineralised bands varied between 10cm to 60cm in apparent thickness. Assay results and radiometric data from Trench 1 indicate a sub-horizontal zone of mineralisation extending from approximately 0.25 - 0.5 metres below surface to the base of the trench. The thickness of the mineralised zone cannot be determined until deeper excavations are completed as high grade assays continued to the base of the trench.
Selective grab samples were also collected from Trench 1. These samples contained visible secondary uranium mineralisation with the results and descriptions summarised in Table 1.

In addition to the trench samples, surface samples were collected from the
broader area of the anomalous zones via shallow sample pits. Many of these
samples have returned values in excess of 100ppm uranium indicating a broader
zone of anomalous values away from the trenches. A full evaluation of this data
will be conducted when all results are received.
Current Field Program
A field program has commenced this week in the area with the aim of:
- Extending the detailed ground radiometric evaluation of the Henri anomaly area
- Conducting ground radiometric surveys over potential strike extensions particularly to the northeast.
- Conducting further trenching and sampling of radiometric anomalies.
- Evaluating access for drilling equipment for a program to be conducted in 2007.
A detailed low level airborne radiometric survey to assist locating further anomalous zones in the project area will be conducted in 2007, contingent upon availability of aircraft and suitable weather conditions.
Tabulation of all results received to date is shown in Table 2.
