Power Minerals Launches Major 10,000m Drilling Campaign at High-Grade Brazilian Niobium-REE Discovery
Power Minerals Limited (ASX: PNN) has commenced its most ambitious drilling program to date at the Santa Anna Niobium-REE Project in Brazil, targeting one of the most promising alkaline carbonatite complexes discovered in recent years. The Power Minerals drilling campaign in Brazil represents a significant escalation in the company's exploration efforts, designed to unlock the full potential of a deposit that has already delivered exceptional high-grade results.
This third phase of drilling builds upon Power's successful maiden 29-hole, 2,272m RC program and 1,000m auger drilling campaign, which intersected extensive zones of niobium mineralisation and multiple zones of high-grade rare earth elements (REE). The new program aims to expand the mineralised footprint both laterally and at depth, with drilling expected to continue until late March 2026.

Exceptional Grade Continuity Drives Expansion Strategy
The decision to launch this major campaign stems from outstanding results from previous drilling, particularly drillhole MN-RC-009, which delivered a remarkable 51m at 11,630ppm (1.16%) TREO from surface to end of hole. Critically, this hole remained in mineralisation when drilling ceased, with the final metre still returning 5,687ppm TREO, indicating significant potential for grade continuity at depth.
The weighted average result from MN-RC-009 also included 1,787ppm MREO (Magnetic Rare Earth Oxides), comprising:
- 1,268ppm Nb2O5 (niobium oxide)
- 464ppm Nd2O3 (neodymium oxide)
- 9.2ppm Tb4O7 (terbium oxide)
- 37.5ppm Dy2O3 (dysprosium oxide)
These magnetic rare earth elements are particularly valuable, as they're essential for permanent magnet applications in electric vehicles, wind turbines, and advanced electronics.
Managing Director Mena Habib commented: "The third drilling program at the Santa Anna Project will allow us to rapidly test new target areas and provide additional key data to support the estimation of an Exploration Target and/or a Mineral Resource Estimate. We have successfully completed an auger program aimed at identifying niobium and rare earth elements (REE) mineralisation within the shallow, weathered zone."
Vast Untested Territory Offers Significant Upside
Perhaps most compelling for investors is the scale of untested potential remaining at Santa Anna. Analysis reveals that only 34 drillholes from a total of 272 have reached depths below 51 metres (the final depth of the high-grade MN-RC-009 hole). Using a conservative 40-metre buffer zone for potential mineral resource blocks, the representative area sampled below 51 metres covers just 13.7 hectares, or 2.4% of the entire 5.8km² Alkaline Complex surface area.
| Key Drilling Statistics | Current Status |
|---|---|
| Total drillholes completed | 272 holes |
| Holes deeper than 51m | 34 holes (12.5%) |
| Complex surface area | 5.8km² |
| Area tested below 51m depth | 13.7 hectares (2.4%) |
| Untested area | 97.6% of complex |
This data highlights the exceptional exploration upside, with the vast majority of the alkaline complex remaining untested at depth where the highest-grade mineralisation has been encountered.
Understanding Alkaline Carbonatite Complexes: Critical Mineral Factories
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 unique mineralogical environments that concentrate valuable elements.
Formation and Characteristics
Carbonatites form when mantle-derived magmas rich in carbon dioxide rise through the Earth's crust. As these magmas cool and crystallise, they create distinctive rock types that preferentially concentrate rare metals. Furthermore, the alkaline nature of these systems creates chemical conditions that allow niobium, rare earth elements, and other critical minerals to accumulate in economic concentrations.
Global Significance
These formations host approximately 95% of global niobium production and significant portions of world REE supply. Major producing carbonatites include Brazil's AraxĂ¡ and CatalĂ£o complexes (niobium), China's Bayan Obo deposit (REE), and Greenland's Kvanefjeld project (REE).
Why Carbonatites Matter for Investors:
- They typically host multiple critical minerals in economic concentrations
- The weathered surface zones often contain easily extractable, high-grade mineralisation
- Fresh rock at depth can extend mineralisation significantly
- Many of the world's largest REE and niobium deposits are carbonatite-hosted
Santa Anna represents a rare opportunity to acquire an entire alkaline complex within a single tenement package—a geological and commercial advantage that's increasingly difficult to secure in today's competitive critical minerals landscape.
Strategic Drilling Program Targets High-Value Zones
The current 10,000-metre program employs industry-standard RC drilling with systematic 1-metre sampling to ensure continuous representation of the mineralised profile from surface to depth. The campaign specifically targets:
- Western extension areas following magnetic anomalies
- Deeper niobium and REE zones in previously untested areas
- Core zone expansion around known high-grade intersections
- Southern section exploration where no drilling has occurred
Quality Control Measures
Power Minerals has implemented comprehensive quality assurance and control (QA/QC) protocols to ensure data reliability:
- Field duplicates and blanks inserted regularly
- Certified reference material (CRM) standards
- Industry-standard sample preparation and analysis
- Lithium metaborate fusion with ICP-MS analysis
- Secure sample packaging and transport to certified laboratories
The comprehensive approach ensures data reliability for future JORC-compliant mineral resource estimates. Consequently, the Power Minerals drilling campaign in Brazil follows best practice standards throughout the exploration process.
Project Acquisition Strengthens Strategic Position
Power Minerals completed the acquisition of the entire 17.05km² Santa Anna Project in December 2025, securing 100% ownership of both tenements covering the complete geophysical anomaly area. This acquisition, following a successful option period, positions Power as the sole beneficiary of any discoveries across the entire alkaline complex.
The project's location in GoiĂ¡s State, central Brazil, places it within an established mining jurisdiction with well-developed infrastructure and supportive regulatory frameworks for critical mineral development. Additionally, Brazil's position as the world's largest niobium producer provides operational context and potential processing advantages.
Comprehensive Exploration Database
Power now controls an extensive database comprising:
- 29 RC holes and 51 auger holes completed by Power Minerals
- 121 air core holes, 38 auger holes, 16 RC holes, and 17 diamond drill holes from previous operators
- Comprehensive geophysical surveys including magnetic and radiometric data
- Detailed geological mapping and sampling programs
This database provides exceptional foundation data for resource estimation and mine planning activities.
Investment Timeline and Upcoming Catalysts
Immediate Catalysts (Q1 2026):
- Drilling results from the 10,000m program (expected throughout March)
- Regular sample data supporting mineralisation model development
- Potential Exploration Target or Mineral Resource Estimate updates
Medium-term Developments:
- Completion of comprehensive drilling by late March 2026
- Integration of all drilling data into updated geological models
- Potential advancement toward preliminary economic assessment
The systematic approach to data collection and analysis positions Power to rapidly advance Santa Anna through the exploration and development pipeline. However, each drilling result builds toward a comprehensive understanding of the deposit's scale and grade characteristics.
Critical Minerals Market Context
The timing of Power's drilling expansion aligns with growing global demand for critical minerals. Niobium consumption continues to grow driven by high-strength steel applications in infrastructure and automotive sectors, whilst rare earth elements face increasing demand from permanent magnet applications in electric vehicles and renewable energy systems.
Brazil maintains its position as the dominant global niobium supplier, producing approximately 85% of world supply from carbonatite-hosted deposits. This established supply chain infrastructure provides potential operational advantages for Santa Anna's development.
Key Investment Metrics:
