NEW URANIUM ANOMALIES DISCOVERED AT DOUGLAS RANGE PROJECT, NT
Yellow Rock Resources Ltd (YRR) is pleased to announce that Australian Uranium Ltd (AUL), a controlled entity of YRR has located at least two significant uranium anomalies on its Douglas Range tenement (E25339) in the Northern Territory.
This area has a lack of publicly-reported history of uranium mineralization and the Northern Territory Geological Survey (NTGS) sample and drilling database contains only minor reference to uranium occurrences in soils (BMR 1980’s data).
The uranium anomalies are located on the northern and central parts of the Douglas Range tenement (E25339) and are distributed across two transect lines. The northern reconnaissance traverse (West McKinley area) is approximately 0.6 kilometres in length and the central traverse (Central area) is 14 kilometres long. Both traverses show strong zones of high uranium response (between 3 and 10 times background value) from
radiometric material confirmed from 80-metre spaced scintillometer readings.
The area of interest at West McKinley is located within the drainage basin of the McKinley River and probably represents palaeochannel deposits under recent alluvium or sheetwash. The Central anomaly is spread over a wide area and spans several geological
environments including Proterozoic basement metasediments and Palaeozoic platform cover sediments.
The two traverses and the lease geology are shown in Figure 1 and the West McKinley anomaly is shown in Figure 2.
During the July fieldwork campaign at Douglas Range Project the following uranium anomalies were identified from confirmed and test-calibrated scintillometer readings:
�� McKinley (600m long) – anomalies to 210 cps (65 cps background)
�� Central (14,000m long) – anomalies to 220 cps (50 cps background)

The instruments used for ground surveys were Scintrex and Geogamma portable scintillometers. Surveys were conducted along lines at sample intervals of 80 metres. The areas tested were checked and calibrated at the start and end of each line. Also comparison readings were made between the two scintillometer models over the same lines with repeat readings. A very close degree of correlation between Scintrex and
Geogamma readings showed that the measurements against background levels were comparable and that the uranium anomalies were validated in both cases.
YRR is planning further ground radiometric surveys on a grid pattern so that the full extent of the two anomalous zones can be evaluated. This will be accompanied by a geological, geophysical and geochemical investigation of the structures that are host to these anomalous readings. This will assist YRR to identify potential drill targets for the next phase of exploration.
