Callabonna Uranium has said that the partial extraction soil survey to define the drill targets over the company’s Denison Rare Earth/Uranium Project in the Northern Territory will commence soon.
The survey will use a partial extraction method that relies on detecting highly mobile metal ions, which can travel through shallow cover sequences highlighting the mineralization.
The Denison project is located approximately 250km north west of Alice Springs, within the Arunta Inlier geological province and covers a total area of 422sq km.
Arafura Resources Nolans Bore Rare Earths deposit is located approximately 90km to the southeast of Denison.
The Arunta Inlier is considered to be highly prospective and largely under-explored terrain.
Historic exploration yielded significant rock chips assay records, which includes uranium values up to 1297 ppm U3O8 and Rare Earth Elements between 100<1000ppm.
The Proterozoic Wangala granite outcrops as a range of hills through the southern part of the lease and contains highly elevated background uranium contents ranging from 15-40ppm.
The company has recently conducted reconnaissance additional mapping and geochemical sampling of the outcropping Wangala granite.
Ground traverses assisted with scintillometer and spectrometer instrumentation has successfully delineated numerous anomalous zones of uranium mineralization across the outcropping granite range.
Mineralization appears to be associated with the dominant structural grain of the granite along a north-easterly trend.
An extensive Mobile Metal Ion (MMI) geochemistry survey is planned to evaluate areas of basement under cover.
Following the completion and analysis of the soil sampling program, exploration drilling is planned to test the best anomalies (outcropping and covered).
