Minas Americas

A magnet-rich rare-earth system, with Nd, Pr, Dy and Tb at the centre of the project's strategic focus, supported by 879 holes in the combined assay compilation.

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.

Field programme · Minas Americas

Drilling recorded through

More than 12,000 metres drilled in 2026.

Magnes is advancing the field programme at Minas Americas, with more than 12,000 metres drilled during 2026—a measure of drilling activity, separate from the assay results published to date.

The next step is to turn fieldwork into checked geological and assay data. Drilling metres alone do not establish mineralisation, continuity, a mineral resource or economic viability.

Drilling progress is not the published assay total.

The 6 October 2026 release reports 879 holes and 7,468.8 m assayed cumulatively. Physical drilling and this dated assay population are different measures.

CHAPTER 1 · THROUGH 16 JUNE 2026

The visual below preserves the selected shallow intervals and 253-hole aggregate reported in the June update. It is retained as a dated part of the project record.

Shallow mineralisation repeated across selected June intervals

Shallow. Repeated. Twelve selected new hole-level intervals from the 16 June 2026 assay update, all beginning at surface and compared on one common 0 to 15 metre scale. The intervals are ordered by TREO, not spatial position, with the full 253-hole June dataset summarized separately.
Table 1 of the 16 June 2026 release listed 12 selected new hole-level intervals, each beginning at surface, with drilled lengths from 6 to 14 metres. Selected interval data, in descending TREO order: MAV_AD_0200, 0 to 10 metres, 9,736 ppm TREO and 2,407 ppm MREO; MAV_AD_0288, 0 to 10 metres, 9,090 ppm TREO and 2,121 ppm MREO; MAV_AD_0299, 0 to 8 metres, 8,998 ppm TREO and 2,327 ppm MREO; MAV_AD_0138, 0 to 6 metres, 8,608 ppm TREO and 2,242 ppm MREO; MAV_AD_0287, 0 to 6 metres, 8,548 ppm TREO and 2,196 ppm MREO; MAV_AD_0237, 0 to 14 metres, 8,527 ppm TREO and 1,954 ppm MREO; MAV_AD_0205, 0 to 11 metres, 8,113 ppm TREO and 1,761 ppm MREO; MAV_AD_0097, 0 to 8 metres, 7,965 ppm TREO and 1,845 ppm MREO; MAV_AD_0077, 0 to 12 metres, 7,927 ppm TREO and 1,811 ppm MREO; MAV_AD_0320, 0 to 6 metres, 7,698 ppm TREO and 2,018 ppm MREO; MAV_AD_0201, 0 to 12 metres, 7,677 ppm TREO and 1,764 ppm MREO; and MAV_AD_0236, 0 to 8 metres, 7,654 ppm TREO and 1,868 ppm MREO. Across the 253-hole June dataset, the disclosed length-weighted averages were 3,640 ppm TREO and 800 ppm MREO. The 16 June 2026 release reported 94 hole-level composites at or above 4,000 ppm TREO over 826 metres, including 17 at or above 7,000 ppm TREO over 163 metres.

SGS BENCH-SCALE PROGRAMME

From diagnostic screening to process-development decisions.

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.

Reporting of the SGS bench-scale results is the next milestone, after results reconciliation and technical review.

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.

Review the next milestone

Selected shallow diagnostic leach results

Magnet and heavy rare earths gain share in solution. Four selected 2025 trench intervals and one later auger interval compare original-sample and dissolved-mix MREO and HREO shares. HREO share more than doubles in all five selected diagnostic tests. Composition comparison, not extraction recovery.

Magnet and heavy rare earths gain share in solution. Figure 2 from the 6 October 2026 release: four selected 2025 trench intervals, plus a later auger interval. HREO represented 6.6–12.1% of the dissolved rare-earth mix, compared with 3.0–4.1% in the original samples.

These are composition shares, not extraction recovery or an increase in absolute solution concentration. MREO and HREO overlap through DyTb and must not be added. Selected diagnostic tests are separate from the current SGS bench programme and do not establish an optimised flowsheet or project-wide recovery.

Diagnostic composition · October source basis

These are the five selected historical diagnostic intervals, not the seven geological samples in the separate SGS bench-scale programme. Values describe desorbed oxide equivalents on the laboratory mg/kg reporting basis—not increased absolute solution concentration or recovery.

Magnet-Rich in Solution. Five selected shallow SGS diagnostic intervals compared on one common zero-to-700 milligram-per-kilogram scale, with magnet rare-earth oxides highlighted within DREO in solution.
Five selected shallow intervals were tested using the same SGS ICM694 diagnostic method: 0.5 molar ammonium sulphate, nominal pH 4, for 30 minutes. PT-34 from zero to one metre returned 161 milligrams per kilogram MREO in 383 milligrams per kilogram DREO, a 41.9 percent magnet share. PT-34 from one to two metres returned 240 milligrams per kilogram MREO in 578 milligrams per kilogram DREO, a 41.6 percent magnet share. These are two consecutive one-metre intervals from surface. PT-36 from zero to one metre returned 278 milligrams per kilogram MREO in 667 milligrams per kilogram DREO, a 41.6 percent magnet share. PT-42 from zero to one metre returned 167 milligrams per kilogram MREO in 383 milligrams per kilogram DREO, a 43.6 percent magnet share. A later shallow-auger test, MAV_AD_0002 from two to three metres, returned 237 milligrams per kilogram MREO in 492 milligrams per kilogram DREO, a 48.1 percent magnet share. Across the five selected intervals, MREO represented 22.2 to 26.3 percent of TREO in the original samples and 41.6 to 48.1 percent of DREO in solution. This is a composition comparison, not recovery. Each displayed value is a solution concentration, not a recovery percentage. DREO means total desorbable rare-earth oxides expressed as oxide equivalents; MREO comprises the neodymium, praseodymium, dysprosium and terbium oxides. Values are on the laboratory reporting basis. The tests were diagnostic, not optimised, and the results are selected.

HOW TO READ THE RESULT

An initial solution response.

Four selected 2025 trench intervals and one later auger interval show what entered solution under the same mild diagnostic method. Representative extraction, mass balance and impurity work come next.

Metallurgy and product pathway
Rare earths in solution; uranium below the laboratory detection limit in all three selected results. The exact uranium and thorium concentrations are shown for PT-36, PT-34 and PT-42.
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. The selected intervals were PT-36 from zero to one metre, with 667 milligrams per kilogram DREO, uranium below 0.04 milligrams per kilogram and thorium at 2.59 milligrams per kilogram; PT-34 from one to two metres, with 578 milligrams per kilogram DREO, uranium below 0.04 milligrams per kilogram and thorium below 0.20 milligrams per kilogram; and PT-42 from zero to one metre, with 383 milligrams per kilogram DREO, uranium below 0.04 milligrams per kilogram and thorium at 2.92 milligrams per kilogram. SGS Geosol used method ICM694: 0.5 molar ammonium sulphate, initial pH 4 and 30 minutes, with ICP-OES and ICP-MS measurement. DREO is oxide-equivalent; uranium and thorium are reported as elemental concentrations. A less-than sign means below the stated laboratory detection limit, not zero. 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.

Regional execution experience

Prior operating experience. Project-specific evidence still comes first.

Cristiano Veloso previously led a mineral business in Minas Gerais through exploration, permitting, financing, mine and plant construction, commissioning and production.

That historical record includes two mines, three plants—two mineral-fertilizer plants and one bioproduction facility—and infrastructure extending to roads, a new bridge and a high-voltage grid connection.
