Power Minerals Delivers Exceptional Santa Anna Drill Results in Brazil

Power Minerals Delivers Exceptional High-Grade Results at Brazil's Santa Anna Project

Power Minerals Limited (ASX: PNN) has announced outstanding power minerals santa anna drill results from its latest auger drilling program at the Santa Anna Niobium-REE Project in Brazil, with the final six drillholes delivering some of the highest grades reported to date. These results continue to validate the exceptional resource potential of this advanced critical minerals exploration opportunity.

Furthermore, the latest findings demonstrate the consistency of high-grade mineralisation across the project area, significantly enhancing confidence in the deposit's commercial potential.

Outstanding Intercepts Drive Resource Confidence

The latest batch of results from holes MN-TM-052 to MN-TM-057 has delivered remarkable high-grade intercepts across 81.0 metres of total sampled intervals. These Power Minerals Santa Anna drill results represent some of the most impressive grades encountered in the program to date.

TREO (Total Rare Earth Oxides) Highlights:

• 14m at 6,081 ppm TREO from surface to end-of-hole, including 3m at 15,436 ppm (1.54%) TREO from 11m (MN-TM-057)
• 14.5m at 5,904 ppm TREO from surface to end-of-hole, including 2m at 12,003 ppm (1.20%) TREO from 12m (MN-TM-056)
• 8.5m at 6,900 ppm TREO from surface to end-of-hole, including 2m at 13,082 ppm (1.31%) TREO from surface (MN-TM-054)

Niobium (Nb₂O₅) Highlights:

• 13.5m at 3,529 ppm Nb₂O₅ from surface to end-of-hole, including 4m at 4,942 ppm Nb₂O₅ from 7m (MN-TM-055)
• 3m at 4,019 ppm Nb₂O₅ from 11m to end-of-hole (MN-TM-057)

In addition, these exceptional intercepts demonstrate the shallow nature of the high-grade mineralisation, which could significantly benefit future mining development costs and project economics.

"These latest results, from the last six holes, in our shallow auger drilling program have delivered further exceptional results, consistent with previous results from the program. The latest results further solidify our confidence in the substantial resource potential within the shallow weathered zone." – Mena Habib, Managing Director

Understanding TREO: A Critical Metric for Rare Earth Projects

Total Rare Earth Oxides (TREO) represents the combined concentration of all rare earth elements converted to their oxide forms, providing a comprehensive measure of rare earth mineralisation intensity. TREO includes both Light Rare Earth Elements (LREE) like lanthanum and cerium, and Heavy Rare Earth Elements (HREE) including the highly valuable dysprosium and terbium.

For investors, TREO grades above 5,000 ppm (0.5%) are generally considered significant in carbonatite-hosted deposits. However, grades exceeding 10,000 ppm (1.0%) are exceptional in the industry.

Power's results, with multiple intercepts above 12,000 ppm (1.2%) TREO, place Santa Anna among the higher-grade rare earth projects globally. Consequently, these Power Minerals Santa Anna drill results significantly enhance the project's attractiveness to potential development partners and investors.

Major 10,000m Drilling Campaign Now Underway

Building on the success of the 57-hole auger program, Power has commenced an ambitious 10,000-metre reverse circulation (RC) drilling campaign. This third phase of drilling will substantially expand the understanding of the deposit's geometry and grade distribution.

Immediate Objectives:

• Test deeper portions of the carbonatite complex beyond the 15-metre auger penetration
• Extend the mineralised footprint to the east and southeast of existing drilling
• Target high-grade niobium mineralisation using new drone magnetic survey data

Program Structure:

• Initial 2,000 metres across approximately 40 holes currently underway
• Systematic grid-based approach building on extensive existing dataset
• Integration with recently completed drone aerial magnetic-DEM survey for targeting

The deeper drilling campaign represents a critical inflection point, potentially unlocking significant additional resource potential beneath the proven near-surface mineralisation. Furthermore, this expanded program will provide essential data for the upcoming resource estimation process.

Advanced Project Status and Near-Term Catalysts

Maiden Resource Estimate Imminent

Power has engaged SRK Consulting to deliver the project's maiden Mineral Resource Estimate, expected in the current quarter. This milestone will provide the first formal quantification of Santa Anna's resource potential and establish a foundation for future development studies.

For instance, the resource estimate will incorporate all available drilling data, including the exceptional Power Minerals Santa Anna drill results from recent campaigns. This comprehensive evaluation will enable more accurate project valuation and development planning.

Complete Project Ownership

Following completion of its Santa Anna acquisition in December 2025, Power now owns 100% of the entire 2.5km alkaline carbonatite complex. This strategic control eliminates joint venture complexities and provides maximum flexibility for future development decisions.

Moreover, complete ownership enables streamlined decision-making and eliminates potential conflicts with joint venture partners during critical development phases.

Technical Program Advancement

• Mineralogical studies planned to understand host minerals for Nb and REEs
• Metallurgical test work to follow, optimising plant design requirements and recovery potential
• Geophysical data integration from new drone survey enhancing targeting precision

Investment Thesis: Critical Minerals in a Strategic Location

Project Fundamentals

Santa Anna represents a rare opportunity in the critical minerals space, combining exceptional grades with strategic location advantages. The recent Power Minerals Santa Anna drill results further strengthen this compelling investment proposition.

Market Context

Brazil supplies approximately 90% of global niobium production, primarily from CBMM's operations. The country's established niobium processing infrastructure and technical expertise provide Santa Anna with significant competitive advantages for future development.

Additionally, the rare earth element market continues to strengthen as global supply chain diversification accelerates. Projects like Santa Anna offer potential alternative supply chain solutions outside traditional dominant producers.

However, this market dominance also presents opportunities for new projects in established mining jurisdictions with proven infrastructure and regulatory frameworks.

Why Investors Should Track Power Minerals

Near-Term Catalysts

1. Maiden Resource Estimate – Q1 2026 delivery will establish formal resource base
2. 10,000m Drilling Program Results – Systematic release of deeper drilling results
