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

    First reported on MINING.com

    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.

    Fortuna’s Diamba Sud gold ESIA approval: design and schedule notes for engineers

    Fortuna Mining has secured Senegalese government approval of the environmental and social impact assessment for its Diamba Sud gold project in eastern Senegal, clearing a key hurdle ahead of a mining permit decision following its 4 Feb 2026 application. A 2025 preliminary economic assessment reported an after-tax IRR of 72% and a US$563 million NPV (5% discount rate) at US$2,750/oz gold, with a 2026 project budget of US$100 million and final investment and construction decision targeted by mid‑2026. For engineers, the ESIA decree signals regulatory alignment for detailed design, site preparation and construction planning.

    Phoenix Tailings’ $500m Pentagon loan: midstream rare earths lens for mine planners

    Rare-earth refiner Phoenix Tailings has secured a conditional $500 million long-term loan from the US Pentagon’s Office of Strategic Capital to build its ‘Freedom Facility’, anchoring an approximately $1 billion financing package for domestic rare earth midstream processing. The plant, targeted to start initial operations in 2028, will provide large-scale separation and metallisation of both light and heavy rare earths from concentrates, recycled materials and secondary feedstocks, complementing existing metallisation sites in Burlington, Massachusetts, and Exeter, New Hampshire. For miners and recyclers, this creates a US-based outlet for mixed rare earth feed, reducing reliance on Chinese processors and tightening mine-to-magnet integration.

    Switzerland loses its shine as central bank gold vault: demand signals for miners

    Central banks added a net 17 tonnes of gold in April and have accumulated about 1,000 tonnes over the past four years, yet the share stored with the Swiss National Bank has halved to 6% from 12% as institutions diversify away from Switzerland’s traditional neutrality. Nearly 90% of reserve managers expect to increase gold holdings, while 74% expect to cut US dollar reserves within five years, with advanced and emerging economies now aligned on this view. About half plan to fund new gold via local-currency domestic programmes rather than selling dollars, creating a structurally different demand channel for gold miners.
