The investment case
What supports the thesis—and what could break it.
01What is the investment hypothesis?+
Minas Americas has produced enough early geological and diagnostic evidence to justify serious follow-up. Future value depends on establishing scale, continuity, representative recovery, manageable impurities, a credible product route, permits, economics and financing.
02Why do magnet rare earths matter?+
Nd and Pr are important inputs to high-performance permanent magnets; Dy and Tb can improve performance at elevated temperatures. Supply concentration rises further downstream into separation and magnet manufacturing. Read the source in context
03Why might Minas Americas be different?+
The combined assay compilation covers 879 holes and 7,468.8 assayed metres at the 25 September 2026 cutoff. It includes prior results and complete or partial assay coverage; it is not all-new drilling or gross physical drilling. MAV_RC_0001 returned 53 metres from surface at 1,242 ppm MREO, including 30 metres at 1,950 ppm MREO. A selected 5-metre interval in MAV_RC_0054 returned 3,310 ppm MREO and 90 ppm DyTb. The project also has selected diagnostic solution responses that warrant representative metallurgy. Those facts merit follow-up; they do not establish a resource, continuity or recovery.

04What is the strongest current evidence?+
MAV_RC_0063 returned 30 metres from surface at 1,853 ppm MREO, including 60 ppm DyTb, with 270 ppm HREO. MAV_AD_0691 returned 8 metres from surface at 2,194 ppm MREO; MAV_AD_0639 returned 11 metres from surface at 2,179 ppm MREO and 335 ppm HREO. These are selected cumulative auger profiles, not an all-new cohort. They are selected head-grade drilled intervals, not project averages, recovery results or evidence of economics. Read the source in context Continue reading
05What is the next technical milestone?+
Reporting of the SGS bench-scale results is the next milestone, after results reconciliation and technical review. SGS bench work covers seven geological samples from four auger holes plus one quality-control duplicate. Leach liquor, two separately analysed washes and residue were tested. No numerical results from this programme are disclosed here. An optimised flowsheet and commercial recovery have not been established; timing and outcomes are not guaranteed. Continue reading
06Which result would most increase conviction?+
A defensible mineral resource combined with representative, element-by-element recovery and a complete impurity mass balance would materially improve the ability to assess potential value.
07Which result would most reduce conviction?+
Insufficient geological continuity or low and inconsistent recovery of Nd, Pr, Dy and Tb across representative material would directly weaken the thesis.
Technical questions
How to read the drilling, metallurgy and impurity data.
01How should the reported RC results be read?+
MAV_RC_0001 returned 53 metres from surface at 1,242 ppm MREO, including 30 metres at 1,950 ppm MREO. A selected 5-metre interval in MAV_RC_0054 returned 3,310 ppm MREO and 90 ppm DyTb. Selected head-grade drilled intervals, not recovered grades. True widths and continuity between holes are not established. Nested intervals are included, not additional metres. MREO and HREO overlap through DyTb and must not be added. No mineral resource, reserve, commercial recovery or economic result is established. Read the source in context Continue reading
02What exactly does the June dataset average describe?+
Across the 253-hole June dataset, the disclosed length-weighted averages were 3,640 ppm TREO and 800 ppm MREO. It is a head-grade statistic for the 253-hole June population, not all 297 reported holes, a mineral-resource grade, true thickness or recoverable grade. Read the source in context
03What did the diagnostic leach test measure?+
The current v11-based context describes earlier selected diagnostic intervals on the laboratory mg/kg reporting basis. Comparing the rare-earth shares in head material and the dissolved mix describes composition, not extraction recovery. Those diagnostic intervals are separate from the later SGS bench-scale programme. Read the source in context Continue reading
04Why is leachate concentration not recovery?+
Recovery is the proportion of the original inventory transferred to a defined output. It requires the original sample mass, solution volume, solids-to-liquid ratio and a complete mass balance. A concentration reported in solution does not supply those quantities.
05What is the current radiological evidence?+
In three selected 2025 primary leach solutions, uranium was reported below 0.04 mg/kg in every result; thorium was reported at 2.59 mg/kg, below 0.20 mg/kg and 2.92 mg/kg. Selected diagnostic solution results, not a resource-average or representative radiological dataset. The concentrations do not characterise uranium or thorium in the feed, residue, water, workplace, potential product or property as a whole and do not establish transfer, recovery, mass balance, total radioactivity, product specification, environmental safety or commercial performance. Read the source in context
06Why do uranium and thorium matter to investors?+
Their distribution can affect process design, residues, worker controls, permitting, product acceptance and cost. The next useful work is a representative feed–solution–residue–product mass balance. Continue reading
07Why doesn’t Magnes publish peer rankings?+
Headline comparisons can mislead when projects differ by stage, sample population, oxide definition or test conditions. A useful comparison must match grade with grade, recovery with recovery and equivalent datasets under current, original sources.
Ownership and access
How Magnes is owned, funded and followed today.
01What is Magnes Rare Earths?+
Magnes is a dedicated rare-earth company advancing Minas Americas, an exploration-stage project in Minas Gerais, Brazil. Read the source in context
02Is Magnes separately traded?+
Magnes is Verde AgriTech's subsidiary. No separately traded Magnes security is disclosed. This corporate pathway is separate from the technical work programme. No listing has occurred, no date has been disclosed and no timing or outcome is assured. Read the source in context
03What does MREO mean?+
MREO is defined as Nd₂O₃ + Pr₆O₁₁ + Dy₂O₃ + Tb₄O₇. It is a reporting definition, not “magnet grade,” recovery or a product specification. Read the source in context
04Is there a mineral resource or mine plan?+
No mineral resource, mineral reserve, project economics, production guidance or development decision has been disclosed for Minas Americas. Read the source in context
05Who is funding the work?+
The parent company reported that a 2026 financing was intended to support Minas Americas drilling, metallurgical testing and technical de-risking alongside working capital and general corporate purposes. No separately disclosed Magnes budget, ring-fenced funding amount or runway was identified. Parent-level liquidity and debt do not constitute a Magnes funding commitment, and future work may require additional capital with possible dilution or structural consequences. Continue reading
06How can I follow the next result?+

Glossary
Terms that drive different economic conclusions.
These definitions are simplified; the issued release and applicable reporting standards govern.
- TREO
- Total rare earth oxides as defined in the applicable disclosure. TREO alone does not describe basket value.
- MREO
- Nd₂O₃ + Pr₆O₁₁ + Dy₂O₃ + Tb₄O₇ in the disclosed project definition. It is not “magnet grade.”
- DREO
- The company’s disclosed desorbable rare-earth-oxide measure in the selected diagnostic solution context; not recovery or proof of economic ionic processing.
- Head grade
- The concentration in the original solid sample before processing.
- Drilled interval
- Length measured along the drill hole; not necessarily true thickness.
- Leachate concentration
- Concentration measured in a test solution under stated conditions; not a recovery percentage.
- Extraction or desorption
- The measured fraction of the original inventory transferred into solution under a defined test.
- Flowsheet recovery
- The fraction reaching a defined product after all process stages and losses.
- Payable recovery
- The portion for which a customer would pay after specifications, impurities and commercial deductions.
- Mineral resource
- A formal concentration estimate meeting an applicable reporting standard; none has been disclosed for Minas Americas.
