American Rare Earths (ARR) has completed soil sampling at the Wyoming Halleck Creek Rare Earths Project in Wyoming in the US.
World Industrial Minerals LLC of Arvada, Colorado, undertook surface sampling and presented the results in a report titled "2021 technical report on the Wyoming Halleck Creek Rare Earths Project".
Since 2010, 259 valid samples have been collected across the project with roughly 200 collected in 2021.
The highest grade observed in 2021 includes 5756 parts per million (ppm) total rare earth oxides (TREO) and 552 ppm heavy rare earth oxides (HREO).
This averages out the 3349 ppm TREO in the Overton Mountain Area and 3002 ppm TREO in the Red Mountain Area.
These samples also host high-grade neodymium and praseodymium with average grades peaking at 742 ppm for Overton Mountain and 661 ppm for Red Mountain.
Managing Director Keith Middleton is excited by the results received.
"The release of this report unveils the latest expansion and analysis of our Halleck Creek REE project," Mr Middleton said.
"We are extremely excited about the results of the surface sampling. The TREO grades and the grades of key elements of neodymium and praseodymium in our surface samples accelerates the timetable to perform additional exploration of the project area."
American Rare Earths is now planning to undertake drilling across Overton Mountain and Red Mountain with notice of intent documents filed with the regional Bureau of Land Management field office.
The aim of this drilling will be to better define rare earth element mineralisation and test for mineralisation at depth over the surface anomalies.
If successful, a maiden resource will be released.
Shares in ARR were up a healthy 13.6 per cent on the market and were trading at 18.8 cents at 11:15 am AEST.
