Power Minerals Limited (ASX: PNN) has delivered another set of impressive Power Minerals Santa Anna Project drilling results from its exploration activities in Brazil, with the latest shallow auger program returning exceptional high-grade niobium and rare earth element (REE) intercepts. The standout result includes 1m at 13,590 ppm (1.36%) Nbâ‚‚Oâ‚… from just 8 metres depth, alongside multiple significant REE zones exceeding 1.38% TREO.
These latest results from the 1,000-metre auger drilling program continue to validate Power's exploration model at the recently discovered alkaline carbonatite complex in Brazil's GoiĂ¡s State. Furthermore, with a major 10,000-metre reverse circulation (RC) drilling program set to commence this month, Power is rapidly advancing toward its goal of establishing a maiden Mineral Resource Estimate for this promising critical minerals project.
Outstanding Drill Results Confirm High-Grade Continuity
The latest batch of assay results from drill holes MN-TM-005 through MN-TM-013 has delivered consistently strong grades across both niobium and REE mineralisation. These Power Minerals Santa Anna Project drilling results demonstrate exceptional continuity and grade consistency across the exploration area.

Management Commentary:
"Latest results from our ongoing auger drilling at Santa Anna continue to validate our exploration model and provide confidence about the potential of this project, as we compile drill data to define a maiden Mineral Resource Estimate for the project, which we hope will be substantial."
Managing Director Mena Habib
In addition to these impressive intercepts, the drilling results demonstrate remarkable consistency across multiple drill holes. The fact that many intercepts begin from surface indicates minimal overburden, which could significantly reduce potential development costs.
Understanding Alkaline Carbonatite Complexes: A Critical Mineral Powerhouse
Alkaline carbonatite complexes represent some of the world's most significant sources of critical minerals, particularly niobium and rare earth elements. These geological formations occur when carbon-rich magma intrudes through the Earth's crust, creating concentrated deposits of valuable minerals through a process of chemical alteration and enrichment.
Key Geological Advantages:
- Carbonatites host approximately 95% of global niobium production
- They account for over 60% of world REE production
- These deposits typically feature large tonnages with consistent grades
- The shallow, near-surface mineralisation at Santa Anna significantly reduces potential mining costs
The Santa Anna complex sits within Brazil's GoiĂ¡s Alkaline Province, a world-renowned region for critical mineral deposits. However, the geological setting indicates that many drill intercepts start from surface, suggesting minimal overburden and potentially translating to lower strip ratios and reduced development costs.
What Makes These Deposits Special:
Alkaline carbonatite complexes form through a unique geological process where carbon-rich magma creates ideal conditions for critical mineral concentration. Consequently, the weathering profile at Santa Anna extends to depths of over 30 metres, creating a naturally enriched zone where valuable minerals become concentrated near the surface.
For instance, the consistent high grades observed in the Power Minerals Santa Anna Project drilling results reflect this natural enrichment process. The shallow nature of mineralisation, combined with the extensive untested areas, suggests significant exploration upside potential.
Accelerated Development Timeline Points to Near-Term Catalysts
Power Minerals has outlined an aggressive exploration schedule designed to rapidly advance Santa Anna toward resource definition. Furthermore, this systematic approach aims to build upon the positive Power Minerals Santa Anna Project drilling results achieved to date.
Immediate Milestones (Q4 2025):
- 10,000m RC drilling program commencing November 2025
- Initial 2,000m phase targeting 40 drill holes
- Focus on deeper REE and niobium mineralisation in untested areas
Q1 2026 Targets:
- Completion of initial RC drilling phase
- Assay results from expanded drilling campaign
- Maiden Mineral Resource Estimate preparation
Strategic Expansion Areas:
- Eastern and southeastern extensions of known mineralisation
- Testing of deeper carbonatite complex portions
- Systematic exploration of large areas with no previous deep sampling
The combination of shallow auger drilling for near-surface definition and deeper RC drilling for resource extension represents a systematic approach to rapid resource delineation. However, this dual-phase strategy enables Power to simultaneously advance immediate targets whilst expanding the overall mineralised footprint.
