Australian Rare Earths (ASX:AR3) has confirmed significant uranium mineralisation close to the surface at its Overland project in South Australia, with assays now revealing grades beyond 100 parts per million.

The explorer’s assay results are taken from chemical assaying of a previously drilled hole, OV047, which featured shallow, calcrete-hosted uranium.

Intercepts included two metres at 92ppm U3O8 (triuranium octoxide) from 26m, including one metre at 103ppm U3O8 from 27m; plus one metre at 82ppm U3O8 from 26m; and one metre at 72ppm U3O8 from 31m.

“These results from the first hole where the occurrence of shallow calcrete-hosted uranium was discovered underscore the significant potential of the Overland project,” managing director and CEO Travis Beinke said.

He continued: “The search for both shallow calcrete-hosted uranium, and sedimentary hosted, ISR amenable targets, continues in this frontier uranium play.”

Down-hole gamma responses and in-field pXRF measurements for contained uranium had already been taken for OV047 in the lead-up to drilling.

These Week 14 results confirm the validity of the measurements for AR3.
