Rare Earths Americas’ 44.5% TREO at Shiloh: flowsheet and drilling lens for engineers

30 Second Briefing
Rare Earths Americas has reported rock chip assays up to 44.5% total rare earths oxide (TREO) from monazite-bearing sands at its Shiloh project in Georgia, with 13 surface samples collected across the Newbill and Pipeline properties. The 2026 work programme includes more than 20,000 m of sonic, direct push and diamond drilling to define continuity, scale and grade distribution, alongside drone-based radiometric surveys at the nearby Lazer Creek area, where hole 25-DPLC-015 returned 10.84% TREO from 6.1–6.77 m and 3.52% TREO from 7.35–8.63 m. For mine planners and process engineers, the coarse monazite sand style suggests potential for relatively simple mineral sands-style extraction flowsheets if continuity and tonnage are confirmed.
Technical Brief
- REA plans >20,000 m of sonic, direct push and diamond drilling at Shiloh in 2026.
- Sonic and direct push methods suit unconsolidated monazite sands, improving sample recovery and stratigraphic control.
- Drilling aims to define continuity, scale and grade distribution sufficient for future mineral resource estimation.
- REA interprets Shiloh monazite sands as potential source rock for US coastal plain mineral sands.
- Drone-based radiometric surveying at Lazer Creek has delineated additional along-strike REE targets beyond current drilling.
- Hole 25-DPLC-015 at Lazer Creek intersected two discrete high-grade TREO zones between 6.1–8.63 m.
- Alpha project in Bahia, Brazil, is more advanced, with engineering progressing towards an SK-1300 initial assessment.
- Focus on heavy rare earths for permanent magnets and defence links project economics to strategic supply security.
Our Take
Rare Earths Americas’ current market capitalisation of about $341.8 million sits slightly below the $368–$439.9 million valuation range seen around its oversubscribed NYSE IPO in May 2026, suggesting that even strong TREO grades at Shiloh in Georgia are being weighed against execution and permitting risk in the US coastal plain.
Our database shows only a handful of US- and Brazil-focused heavy rare earth items among more than a thousand Mining stories, so REA’s dual focus on the Shiloh project in Georgia and the Alpha project in Bahia positions it as one of the few listed plays explicitly trying to build a cross-hemisphere heavy rare earths pipeline.
