American Rare Earths (ASX: ARR | OTCQX: ARRNF) has announced promising results from surface geochemistry sampling at its Halleck Creek Rare Earths project. The company collected 88 surface samples across previously unmapped or sparsely mapped expansion areas, including Bluegrass, northern Overton Mountain, and Sommers Flat Area.

Key findings include:

  • Total Rare Earth Oxide (TREO) grades up to 5,280 ppm
  • Most samples at Overton Mountain and Bluegrass show TREO values exceeding 2,770 ppm
  • Four samples exceeded 4,000 ppm TREO

The results demonstrate the upside potential of the Halleck Creek district, with the Bluegrass area identified as a high-priority exploration/expansion target for 2024-2025.

DENVER, Aug. 07, 2024 (GLOBE NEWSWIRE) -- American Rare Earths (ASX: ARR | OTCQX: ARRNF | ADR: AMRRY) (“ARR” or the “Company”) is pleased to announce the release surface geochemistry samples across the Bluegrass, northern Overton Mountain, and Sommers Flat Area at the Halleck Creek Rare Earths project. ARR geologists collected 88 surface samples in June 2024 across previously unmapped or sparsely mapped expansion areas at Halleck Creek. ALS Global assayed the samples which contain TREO values ranging to 5,280 ppm.

Most of the surface samples at 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”), which is the chief rare earth bearing rock type within the Red Mountain Pluton (“RMP”).

The surface samples at the Sommers Flat area vary with changes in the geology. At Sommers Flat the biotite hornblende syenite (“BHS”) is the primary rock type within the RMP. The BHS rocks have lower TREO grades than the CQM. Thin dikes of higher grade CQM cross-cut the BHS rocks at Sommers Flat and range in thickness between 5 and 50 centimetres. Two CQM dike samples contained 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.”

Technical Information
ARR geologists collected 88 surface rock samples across the northern Overton Mountain, Bluegrass and Sommers Flat resource areas at the Halleck Creek Rare Earths Project, Figure 1.

After the current exploration drilling at the Cowboy State Mine (CSM) area concludes, ARR geologists will update exploration drilling plans for Bluegrass and northern Overton Mountain and submit applications to the BLM and the WDEQ for 2025. ARR is also working to secure long-term exploration agreements with surface owners adjacent to the Bluegrass area.
