Adavale Resources has identified extensive helium anomalies in a desktop study of its Lake Surprise uranium project in South Australia – which are potential pathfinders for the presence of uranium.

The study analysed the presence of helium spectral signatures from the radioactive decay of uranium, with several of the helium anomalies coincident with elevated gamma in the regional geophysical data.

The company says this strongly indicates the presence of uranium.

Especially considering the correlation seen between helium signatures and uranium occurrences at known uranium deposits such as the Beverly mine to the southeast of Adavale Resources’ (ASX:ADD) tenements.

Prospective tenement package

“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,” Adavale senior exploration geologist Patrick Harvey said.

“This survey and resulting information provide an extra layer of data that builds upon our understanding of the tenements to support the upcoming geophysical survey.”

Exploration is scheduled to begin as soon as Covid-19 related travel restrictions ease for entry into South Australia from the ACT. 

Ground-based gamma survey planned

The radiometric gamma anomalies that are the target of the planned exploration at the project were never tested historically and are the initial targets for the company’s upcoming exploration program.

The company will conduct a 1,100 line km ground-based gamma survey, focusing on one gamma anomaly of 1.8km x 8km – which is much larger and stronger than the one defined by historic drilling in the northwest of the tenement.

The investigation will focus on linking the helium signatures associated with gamma anomalies defined in the survey and determining the relationship between helium, gamma and uranium mineralisation.

New tenement application lodged

Adavale has also applied for a new tenement to the west of Lake Surprise which covers large coincident gamma and helium anomalies.

The information from the desktop study was not available at the time of application – but the company says this improves the prospectivity of the area greatly.

The application is currently under the consideration of the Department for Energy and Mining and no ground-based exploration will be completed on the area, until the tenement has been granted.
