Strategic Positioning in Brazil's REE Landscape
Gold Mountain's Down Under Project is strategically located in Bahia State, eastern Brazil, positioning the company within a region known for its diverse mineral endowments. The project encompasses 136 granted tenements with 100% ownership, providing the company with significant exploration upside across a substantial land package.
The Central Prospect represents a key focus area within this broader project, where systematic exploration is revealing the true scale of REE mineralisation potential. Moreover, the latest results build upon previous announcements, demonstrating the company's methodical approach to defining what could become a significant REE resource.
Gold Mountain Ltd rare earth elements exploration activities have expanded significantly through this comprehensive sampling programme, with the company positioning itself to capitalise on growing global demand for critical minerals.
Comprehensive Exploration Results Deliver Multiple Targets
TREO Anomalies Expand Known Zones
The 281 stream sediment samples have successfully defined strongly anomalous TREO zones that extend the previously identified Central Prospect anomalies. These results demonstrate the expanding scale of the REE province and provide the foundation for upcoming auger drilling programmes designed to define priority diamond drill targets for future resource estimation.
| Exploration Metric | Result |
|---|---|
| Stream sediment samples | 281 samples |
| Sample coverage | 15 tenements |
| Sample spacing | ~1km intervals |
| Drainage length threshold | >500 metres |
| Sample weight | ~1kg each |
Gold Potential Emerges as Secondary Target
The exploration programme has identified significant gold anomalies extending approximately 10km in a northeasterly trend, parallel to regional structure. These anomalies are strongly supported by coincident mercury (Hg), arsenic (As), and in places by sulphur (S) and lead (Pb) anomalies, indicating potential for hard-rock gold mineralisation.
In addition, the gold anomalies appear to be structurally controlled, aligning with major geological structures mapped by regional surveys. This structural control suggests the presence of large-scale mineralising systems with significant exploration potential.
Understanding REE Exploration: What TREO Means for Investors
Total Rare Earth Oxides (TREO) represents the combined concentration of all rare earth elements expressed as their oxide equivalents. This measurement is crucial for investors as it provides a single metric to evaluate the overall rare earth content of a deposit or exploration target.
TREO values in stream sediments indicate the presence of REE-bearing minerals being eroded from upstream sources, essentially providing a roadmap to potential hard-rock mineralisation. Consequently, high TREO values in stream sediments suggest that significant REE accumulations may exist in the catchment area, making them priority targets for follow-up drilling.
Why REE Matter for Modern Technology
Rare earth elements are essential components in clean energy technology, including wind turbines, electric vehicle batteries, and solar panels. These elements also play crucial roles in defence applications, consumer electronics, and advanced manufacturing processes.
The growing global transition to renewable energy has created unprecedented demand for REE, making successful exploration projects increasingly valuable. Countries worldwide are seeking to diversify REE supply chains, creating opportunities for new producers in stable jurisdictions like Brazil.
For Gold Mountain, the identification of extensive TREO anomalies across multiple tenements indicates the potential for a large-scale REE system. This could support substantial future resources if confirmed through drilling.
Advanced Technical Integration Strengthens Targets
Radiometric Correlation Validates Anomalies
The exploration programme has incorporated radiometric traversing to measure thorium anomalies, which show general agreement with stream sediment TREO anomalies. This correlation is significant because thorium is commonly associated with REE mineralisation, providing independent validation of the stream sediment results.
The radiometric work has revealed that anomalies are present almost exclusively on slopes between old surfaces, suggesting that surface leaching has occurred while concentrating REE-thorium-uranium content at depth. This geological interpretation supports the potential for substantial mineralisation beneath the current surface expression.
Structural Controls Define Target Geometry
The exploration has identified strong northeast structural controls reflected in very linear northeast-trending drainages. Additional major structures include WNW and NNW trends, creating a structural framework that could control both REE and gold mineralisation.
Understanding these structural controls is crucial for targeting future drilling, as both ionic adsorbed clay REE deposits and structurally controlled gold mineralisation often follow predictable geological patterns.
Executive Leadership Highlights Value Creation Potential
"Down Under Rare Earth Project continues to deliver highly positive results, with major TREO extensions to anomalous zones previously identified through our regional stream sediment sampling programme at Central Prospect. With additional auger drilling underway at Irajuba and at Capivara, an ever expanding pipeline of high-quality targets is being defined. I'm confident these programmes will unlock significant value and advance the Company toward defining substantial REE resources."
David Evans, Executive Director
Evans also highlighted the gold potential, noting that "the large-scale gold anomalies identified, particularly where supported by arsenic and mercury, indicate strong gold potential at Central."
Gold Mountain Ltd rare earth elements exploration strategy appears well-positioned to capitalise on the systematic approach to target definition and resource development across the substantial land package.

Technical Foundation Supports Resource Development
What Makes the Geological Setting Advantageous?
The Down Under Project is situated within Middle Archean ortho and para granulite facies rocks and Late Archean high potassium iron-rich A-type granitoid sequences. These geological formations underwent granulite facies metamorphism during the Transamazonian orogeny and were later intruded by Paleoproterozoic post-tectonic charnockitic granites.
This complex geological history has created ideal conditions for REE concentration, particularly in ionic adsorbed clay and residual heavy mineral accumulations associated with deeply weathered profiles. Additionally, post-tectonic potassium-rich pegmatites that cross-cut regional structural patterns are also present.
Mineralisation Style Diversity
Gold Mountain Ltd rare earth elements exploration targets multiple styles of mineralisation, including:
Ionic Adsorbed Clay (IAC) Deposits: These deposits form through weathering processes that concentrate REE in clay minerals, making them relatively easy to extract using conventional techniques.
Hard Rock REE Sources: High-grade monazite-hosted REE-niobium-uranium-scandium mineralisation occurs in small mafic intrusive bodies and Late Archean A-type granitoids.
Structural Gold Systems: Large-scale gold anomalies appear to be controlled by regional structures, suggesting the potential for significant hard-rock gold deposits.
