Adavale Resources (ADD) has identified helium anomalies at its Lake Surprise uranium project in South Australia.
The company commissioned a desktop study, which was conducted by Dr Neil Pendock, to analyse the presence of helium spectral signatures from the radioactive decay of uranium within the project.
For context, helium is released as a “daughter” product of radioactive decay as uranium
breaks down into other elements. Helium migrates through the regolith after decay which is then released into the atmosphere.
If the helium released is concentrated enough, it will have a spectral signature in specific wavelengths that can be seen by sensors on satellites or other detection vehicles. These sensors provide data in those specific wavelengths which make the helium visible.
Dr Pendock compared some of the anomalies at known uranium deposits in the region to see how they correlate with those at the Lake Surprise project. As it turns out, several of the helium anomalies are coincident with elevated gamma in the regional geophysical
data which strongly indicates the presence of uranium.
One of the identified anomalies is approximately eight kilometres long and 1.8 kilometres wide and was never historically tested. The company said this provides an exciting target for follow-up.
“The workstream undertaken by Dr Pendock, using the helium data as a pathfinder is well-established and provides additional evidence of the potential presence of uranium, highlighting the prospective nature of Adavale’s uranium tenement package,” Senior Exploration Geologist Patrick Harvey said.
Adavale plans to follow up on the anomalies with a 1100 line-kilometre ground based
radiometric survey which will include targeted outcrop sampling to focus on the priority gamma anomalies. The survey work will aim to link the helium signatures associated with gamma anomalies and determine the relationship between helium, gamma and uranium mineralisation.
Company shares were up 3.64 per cent to trade at 5.7 cents at 10:36 am AEDT.
