Sydney, Australia – August 7, 2024 – American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) ("ARR" or the "Company") is pleased to announce the results of surface geochemistry samples collected across the Bluegrass, northern Overton Mountain, and Sommers Flat Area at the Halleck Creek Rare Earths project.
Highlights:
Mapping and sampling across unsampled areas at the new Bluegrass Resource Area completed
40 surface geochemical samples collected and assayed with Total Rare Earth Oxide ("TREO") grades up to 4,815 ppm
The Bluegrass and Overton Mountain geology consists of homogenous target mineralised material
Reconnaissance scale mapping and sampling across the Sommer's Flat Resource Area performed
48 surface geochemical samples collected and assayed with TREO grades up to 5,280 ppm
Results continue to demonstrate upside potential of the Halleck Creek district.
In June 2024, ARR geologists collected 88 surface samples across previously unmapped or sparsely mapped expansion areas at Halleck Creek. ALS Global assayed these samples, which contain TREO values ranging up to 5,280 ppm.
Most surface samples from Overton Mountain and Bluegrass show TREO values exceeding 2,770 ppm, with four samples exceeding 4,000 ppm TREO. The mapped geology in this area consists almost exclusively of clinopyroxene quartz monzonite (CQM), the primary rare earth-bearing rock type within the Red Mountain Pluton (RMP).
Surface samples at the Sommers Flat area show variation in TREO grades due to geological differences. The biotite hornblende syenite (BHS) is the primary rock type within the RMP at Sommers Flat and typically exhibits lower TREO grades. However, thin dikes of higher-grade CQM cross-cutting the BHS rocks have shown promising results, with two samples containing TREO values of 4,726 ppm and 5,250 ppm.
Dwight Kinnes, Chief Technical Officer, commented:
"The recent mapping and sampling from our geologists clearly show that the Bluegrass area will be a high priority exploration / expansion area for ARR. This area is contiguous to prior drilling at the Overton area, and we plan to perform expanded exploration at Bluegrass and will be updating exploration permits with the Bureau of Land Management (BLM) and Wyoming Department of Environmental Quality ("WDEQ") for 2024-2025. Additional field mapping and sampling at Sommers Flat will provide details on the CQM dikes and help us to determine if long-range exploration of Sommers Flat is warranted."
