Ann: Scoping Study, low-cost, scalable world-class REE Project, page-73

American Rare Earths’ Halleck Creek Scoping Study released:

Earlier this week, American Rare Earths (ARR) announced results of a Scoping Study on its Halleck Creek REE project in Wyoming.

The Study, which was completed by Stantec Consulting, outlined the project's initial capex at $456M and projected a pre-tax NPV10 of $505M and a ~3-year payback period.

Last month the company announced an increased Halleck Creek MRE of 2,342 million tonnes grading 3,196 ppm TREO using a cut-off grade of 1,000 ppm TREO.

In the proposed flowsheet, the REE-bearing allanite ore from Halleck Creek will be concentrated to a grade of 3.5% to 4% at the mine site, then will be separated into oxides of NdPr, Dy, Tb, La and a mixed Sm-Eu-Gd concentrate at a facility to be built near Wheatland, Wyoming. ARR anticipate the completion of a PFS within the next 12 months.


Adamas take: A positive outcome for the Scoping Study although with a relatively low-grade resource and unproven mineralogy at scale, the upcoming PFS will be key to validate the viability of the project.
