Gold Mountain Limited (ASX: GMN) (“Gold Mountain” or “the Company”) has reported fresh results from stream sediment sampling at its Gold Mountain Araxá Project in Brazil. The results point to niobium, magnet rare earth and phosphate anomalies across all four prospect areas.

Gold Mountain added 327 more samples. That brings the total to 515 assays. The anomaly spots match well with magnetic and structural features. This supports doing more drilling to confirm what is there.
What Happened at the Araxá Project
Gold Mountain received assay results from regional stream sediment sampling across the Araxá Project. The results revealed strongly clustered multielement anomalies across niobium, phosphate and magnet rare earth elements.
Magnetic and structural anomalies were found to coincide with these geochemical results. This overlap strengthens the geological case for target definition ahead of drilling.
Work Undertaken by Gold Mountain
Only this heading carries bullet points, as outlined below.
- Assays revealed strongly clustered multielement anomalies across niobium, phosphate and Magnet Rare Earths
- Magnetic and structural anomalies were found coincident with the geochemical anomalies
- Soil sampling and high-resolution magnetics targets were identified, supporting future drill target definition
Why This Matters for Investors
Gold Mountain operates in the critical minerals sector, where niobium and rare earth elements carry growing global demand. Carbonatite complexes in the Araxá region host every known mine or resource nearby.
This compares with a global average of only twenty per cent for such complexes, according to the Company. That statistic underpins why Gold Mountain considers its four prospect clusters highly prospective for the Gold Mountain critical minerals sector.
Who Is Involved
Gold Mountain Limited (GMN) is the Company behind the Gold Mountain Araxá Project exploration programme. Executive Director David Evans provided commentary alongside the announcement.
Peter Temby, an independent consultant and Competent Person, compiled and interpreted the exploration results. He is a Member of the Australian Institute of Geoscientists.
Where the Anomalies Were Found
The Araxá Project sits within the Alto Paranaíba Igneous Province in eastern Brazil. It lies approximately three hundred kilometres west of Belo Horizonte.
Gold Mountain holds four clusters of granted exploration licences there, named Guimarania, Ibiá, Sacramento and Tapira. Each prospect returned coincident niobium, phosphorus and magnet rare earth anomalies.

When the Announcement Was Made
Gold Mountain released this update to the ASX on 10 Sep 2026. It follows an earlier release on 23 Jan 2026, which confirmed the presence of carbonatites across the Project area.
The Company noted that follow-up exploration programs will commence as soon as practical. These programs aim to refine and prioritise drill targets across the tenements.
How the Anomalies Were Identified
Gold Mountain undertook interpretation of the 515 stream sediment samples, including ten orientation samples over known mineralisation. The work focused on Gold Mountain niobium rare earth mineralisation patterns across the tenements.
A suite of rock-forming elements was also assessed. These elements help indicate mafic portions of the complexes where niobium mineralisation is more likely to occur.
Prospect-by-Prospect Breakdown
| Prospect | Niobium Anomalies | Magnet REE Anomalies | Phosphorus Anomalies |
|---|---|---|---|
| Guimarania | Strong, eastern three-quarters of tenement | Present, source likely within tenement | Present, coincident with niobium |
| Ibiá | Strongly coincident with large magnetic anomaly | Peripheral to niobium and phosphorus zones | Coincident with the composite magnetic signal |
| Sacramento | Two coincident clusters identified | Present in one of the two clusters | Coincident with niobium in both clusters |
| Tapira | Four anomalous areas identified | Associated with three of four Nb-P zones | Supported by magnesium, nickel and iron anomalies |

Anomaly Grade Ranges Recorded
| Element | Top Grade Range | Lowest Mapped Range | Unit |
|---|---|---|---|
| Niobium | 16.35 to 6.78 | 2.51 to 1.87 | ppm |
| Magnet Rare Earths | 990 to 175 | 72 to 61 | ppm |
| Phosphorus | 0.90 to 0.43 | 0.10 to 0.07 | ppm |
Gold Mountain Future Workplan
Gold Mountain outlined a staged program for the highest ranked anomalies across its tenements. Niobium targets will receive drone magnetics and grid soil sampling.
Magnet REE and phosphate anomalies will also be advanced through grid soil sampling programs. Stream sediment coverage will extend once landowner access agreements are finalised, alongside environmental approvals sought from local municipal authorities.

Industry Outlook
Demand keeps going up for niobium, rare earths, and phosphorus. This is happening in batteries, steel, and farming. Deposits from carbonatite, including the ones in the Araxá area, still supply a major share of these materials.
The critical minerals sector increasingly favours jurisdictions with established mining infrastructure nearby. Araxá sits close to existing niobium and phosphate mines, supporting Gold Mountain’s exploration thesis.
Future Direction and Impact on Gold Mountain’s Exploration Pipeline
Impact on drill target definition remains the immediate focus for Gold Mountain. Soil sample grids planned across Guimarania, Ibiá, Sacramento and Tapira aim to sharpen priority zones.
According to the Director’s Statement, follow-up exploration programs will commence as practical, advancing the Gold Mountain Araxá Project toward drilling. Environmental approvals from local municipal authorities represent the next procedural milestone.
If landowner access agreements are finalised as planned, stream sediment coverage could expand further. This would support Gold Mountain’s broader ambition across its REE, niobium and lithium portfolio in Brazil.
Colitco will continue tracking Gold Mountain’s progress as drill targets are confirmed across the Araxá Project.
