Rare Earths Americas Hits Dysprosium at Homer in Brazil

Rare Earths Americas (NYSE American: REA) said initial drilling at its Homer project in Brazil returned broad, near-surface rare earth mineralization enriched in dysprosium and terbium, prompting the company to expand its drill program; shares were unchanged at 10.98 as of 17:57 GMT on Sept. 24, 2026.

Rare Earths Americas Inc. (NYSE American: REA) said its first drilling at the Homer project in Brazil intersected broad zones of near-surface rare earth mineralization, and that the material is enriched in dysprosium and terbium — the two elements that matter most to buyers of high-temperature permanent magnets. The company said the results were strong enough to justify expanding the drill program.

Shares were flat at 10.98 as of 17:57 GMT on Sept. 24, 2026, matching the previous close, after trading between 10.54 and 10.99 on the day. The broader tape was slightly lower: the S&P 500 tracker was at $766.87, down 0.12%, with the Nasdaq 100 proxy off 0.22% at $739.58 and the Dow 30 fund down 0.33% at $512.60.

Why dysprosium and terbium are the headline, not the tonnage

Rare earths are not a single commodity. The light end — cerium, lanthanum, neodymium, praseodymium — is comparatively abundant and, in the case of cerium and lanthanum, frequently a by-product nobody has a use for. The heavy end is where scarcity lives, and dysprosium and terbium sit at its commercial centre.

Both are added in small quantities to neodymium-iron-boron magnets to stop them demagnetizing as they heat up. That matters in exactly the applications driving demand growth: electric-vehicle traction motors, which run hot; direct-drive wind turbine generators; and defence actuators and guidance systems, where thermal tolerance is a specification rather than a preference. A magnet producer can substitute around a lot of things. It cannot easily substitute around dysprosium.

That is why an early-stage announcement framed around heavy-element enrichment reads differently from one framed around total rare earth oxide grade. A deposit can carry a headline grade that looks impressive and still be commercially awkward if the split skews to light elements with thin pricing. The reverse — a modest total grade with a favourable heavy fraction — can be the better asset. Rare Earths Americas has put the enrichment claim at the front of its release, which is the claim the market will test in the assays that follow.

The near-surface detail carries the economics

The second word doing work in the company's statement is "near-surface." Brazil's emerging rare earth story is built largely on ionic clay deposits — weathered horizons where rare earth ions sit loosely adsorbed onto clay particles rather than locked inside hard-rock minerals. The geology is the same family that made southern China's heavy rare earth supply possible for decades.

The appeal is cost. Clay-hosted material can sit within metres of surface, which means shallow open pits, low strip ratios and no blasting. More importantly, the rare earths can often be recovered by leaching with a salt solution rather than by crushing, grinding, flotation and high-temperature acid cracking. That removes most of the capital intensity and much of the process risk that has sunk hard-rock rare earth developers elsewhere.

None of that is confirmed at Homer by a first drill program. Grades, widths, depth of the weathered profile and — critically — metallurgical recovery from bench-scale leach testing are the variables that determine whether a promising intercept becomes a project. The company has not, in the material reported by Northern Miner, moved past the drilling stage.

Brazil's pitch to Western magnet buyers

Brazil has spent the past several years positioning itself as the non-Chinese source of clay-hosted rare earths, and Homer joins a growing cluster of projects making that case. The country's advantages are real: favourable weathering geology across large areas, an established mining workforce, hydroelectric power and a permitting regime that developers have generally found navigable.

The obstacle is the same one every Western rare earth project faces. Mining the ore is the easy part. Separating individual rare earth oxides from a mixed concentrate is a chemical engineering problem requiring hundreds of solvent-extraction stages, and the overwhelming majority of that capacity sits in China. A Brazilian producer with excellent heavy-element ratios still needs somewhere to send its concentrate, and the answer to that question determines whether the asset is a mine or a feedstock supplier to a competitor.

That is the strategic context in which drill results like Homer's are being read. Automakers, wind developers and defence primes in North America and Europe have spent three years signing memoranda of understanding with anyone who can plausibly deliver dysprosium outside the Chinese supply chain. Early-stage explorers with the right element split have found that interest translates into financing on terms that would have been unavailable a decade ago.

What the share price is and is not saying

REA's unchanged close on the day is worth reading carefully rather than dismissively. The stock traded as low as 10.54 and as high as 10.99 during the session, a range that indicates the news was contested intraday before the shares settled exactly where they started. On a day when all three major U.S. benchmarks finished in the red, flat is a modest relative outperformance — but it is not the sharp re-rating a genuinely transformational intercept typically produces.

One plausible reading: the market is waiting for numbers. A statement that mineralization is "broad" and "enriched" is qualitative. Until the assay table arrives with intercept lengths and per-element grades, and until the expanded program's scope is quantified in metres and holes, there is limited basis to reprice the equity.

The checkpoints that follow

Three things will determine whether Homer graduates from an interesting first pass.

• The full assay suite. Total rare earth oxide grade is necessary but not sufficient. The number to watch is the proportion of the contained oxide accounted for by the magnet metals — neodymium, praseodymium, dysprosium and terbium — because that fraction, not the headline grade, drives basket value.
• Leach recovery. If the material responds to ambient-temperature salt leaching at high recovery, the project's cost structure changes completely. If it needs acid, it becomes a conventional and far more expensive proposition.
• The expanded program's size and timing. The company has signalled it is scaling up the drilling. How many metres, over what footprint, and on what schedule will indicate whether management is chasing continuity across a large weathered blanket or infilling a narrower target.

Beyond the drill bit, the commercial questions arrive quickly for any rare earth developer that gets encouraging early results: offtake conversations, separation partnerships, and whether Brazilian or third-country processing capacity can be secured before capital markets lose patience. Homer is at the beginning of that sequence, not the end of it.

Frequently asked questions

What did Rare Earths Americas report at Homer?

The company said its initial drilling at the Homer project in Brazil returned broad, near-surface rare earth mineralization that is enriched in dysprosium and terbium. The results were encouraging enough that the company said it would expand its drilling program. Detailed intercept grades and widths were not included in the summary reported.

Why do dysprosium and terbium matter more than other rare earths?

Both are heavy rare earth elements added in small amounts to neodymium-iron-boron permanent magnets to prevent them from losing magnetism at high temperatures. That makes them essential for electric-vehicle traction motors, direct-drive wind turbine generators and defence actuators. They are far scarcer than light rare earths such as cerium and lanthanum, and much harder to substitute.

Where does Rare Earths Americas trade?

Rare Earths Americas trades on NYSE American under the symbol REA. As of the last trade at 17:57 GMT on Sept. 24, 2026, the shares were at 10.98, unchanged from the previous close of 10.98, having traded between 10.54 and 10.99 during the session.

What is an ionic clay rare earth deposit?

It is a weathered geological horizon in which rare earth ions are loosely adsorbed onto clay particles rather than bound inside hard minerals. Because the material sits near surface and can often be recovered by leaching with a salt solution instead of crushing and acid cracking, these deposits typically carry lower capital and operating costs than hard-rock rare earth mines.

Why is Brazil attracting rare earth exploration?

Brazil has extensive tropically weathered terrain suited to clay-hosted rare earth mineralization, an established mining workforce, abundant hydroelectric power and a permitting regime developers have generally found workable. It has become a focus for Western buyers seeking rare earth supply, particularly heavy elements, outside the Chinese-dominated supply chain.

What is the main obstacle for non-Chinese rare earth projects?

Separation. Extracting mixed rare earth concentrate from ore is comparatively straightforward, but splitting it into individual purified oxides requires extensive solvent-extraction circuits, and the overwhelming majority of that capacity is located in China. A developer with good ore still needs a processing route before its output can reach Western magnet manufacturers.
