Power Minerals Ltd Delivers Exceptional High-Grade Results at Santa Anna

Power Minerals Delivers Outstanding High-Grade Results at Santa Anna Project

Power Minerals Limited (ASX: PNN) has delivered exceptional high-grade results Power Minerals Ltd from its ongoing auger drilling programme at the Santa Anna Project in Brazil. The company has achieved multiple intersections exceeding 1% TREO and consistent mineralisation across a 356.75m sampled interval.

The latest assays from holes 26 to 51 have returned standout results including 16,008 ppm (1.60%) TREO and 5,327 ppm Nb₂O₅. These high-grade results Power Minerals Ltd validate the scale and grade potential of the shallow weathered zone at this advanced critical minerals exploration opportunity.

Exceptional Grade Results Validate Resource Potential

Power's systematic auger drilling programme continues to deliver remarkable consistency. Furthermore, multiple drill holes have returned substantial high-grade intersections that demonstrate the project's exceptional potential.

Outstanding TREO Results:

• 16.5m at 4,848 ppm TREO from surface, including 1m at 16,008 ppm (1.60%) TREO in MN-TM-042

• 15m at 6,818 ppm TREO from surface, including 2m at 11,686 ppm (1.17%) TREO in MN-TM-032

• 15.5m at 6,754 ppm TREO from surface, including 12m at 7,346 ppm TREO from 2m in MN-TM-033

• 18m at 3,954 ppm TREO from surface, including 2m at 12,375 ppm (1.24%) TREO in MN-TM-049

High-Grade Niobium Intersections:

• 15m at 2,852 ppm Nb₂O₅ from surface, including 8m at 3,662 ppm Nb₂O₅ in MN-TM-033

• 11m at 4,124 ppm TREO including 2m at 3,422 ppm Nb₂O₅ in MN-TM-045

• 2.5m at 3,519 ppm Nb₂O₅ from 14m in MN-TM-042

The programme has now completed 51 auger drillholes totalling 700 metres. In addition, mineralisation begins at surface and remains open at end of hole in many intersections. This surface-starting mineralisation significantly enhances the project's economic potential by minimising waste stripping requirements.

Understanding Carbonatite Complexes: A Critical Minerals Source

What is a Carbonatite Complex?

Carbonatite complexes are rare geological formations containing unusual igneous rocks composed primarily of carbonate minerals. These formations are globally significant sources of critical minerals, hosting over 90% of the world's niobium production and substantial rare earth element deposits.

Why Santa Anna Matters:

• Surface mineralisation eliminates costly deep mining requirements

• Large-scale system spanning approximately 2.5km east-west

• Weathered zone enhancement through natural upgrading processes that concentrate minerals

• Critical minerals exposure as niobium and REEs are essential for renewable energy technologies

The weathered carbonatite at Santa Anna has undergone natural beneficiation processes. Consequently, valuable minerals have been concentrated in the upper 15 metres through lateritic weathering, creating an exceptionally economic mineralisation style.

Strategic 10,000m Drilling Campaign Set to Commence

Power is advancing to the next phase with an ambitious 10,000m reverse circulation drilling programme. However, this campaign will be executed in strategic phases to maximise efficiency and resource definition.

Immediate Phase (January 2026):

• Initial 2,000m RC drilling across approximately 40 holes

• Target deeper portions of the carbonatite complex

• Extend mineralised footprint east and southeast of current drilling

Technical Advantages:

• Drone aerial magnetic survey completed provides precision targeting for high-grade zones

• 80m systematic grid spacing ensures comprehensive coverage

• Untested areas identified with significant exploration upside in unexplored complex areas

Managing Director Mena Habib commented:
"The consistent, high-grade results from our ongoing auger drilling at Santa Anna validate and enhance our exploration model, and also builds confidence in the significant Resource potential of the shallow, weathered zone."

The company's systematic approach positions it to deliver the first Mineral Resource Estimate for Santa Anna in Q1 2026. For instance, this timeline provides crucial validation for this world-class critical minerals asset.

Complete Ownership of World-Class Asset

Power's recent acquisition of 100% ownership of the entire 2.5km Santa Anna Alkaline Complex represents a strategic coup in the critical minerals space. Furthermore, this complete control provides several key competitive advantages.

Asset Quality:

• Entire complex ownership eliminates joint venture complications

• Advanced exploration stage with substantial historical database

• Surface mineralisation enables low-cost extraction potential

• Critical minerals focus provides exposure to high-demand commodities

Location Benefits:

• Established infrastructure situated 6km from Mundo Novo township

• Highway access adjacent to state highway GO-156

• Capital proximity located 335km from Brasília

• Mining-friendly jurisdiction within Brazil's established mining framework

Investment Thesis: Critical Minerals at Surface

Santa Anna represents a rare combination of high-grade critical minerals, surface accessibility, and large-scale potential. Consequently, these attributes position Power Minerals as a compelling investment opportunity in the critical minerals sector.

Key Investment Drivers:

1. Exceptional Grades: Multiple intersections >1% TREO with consistent high-grade niobium

2. Surface Mineralisation: Eliminates deep mining costs and complexity

3. Critical Minerals Exposure: Niobium and REEs are essential for clean energy transition

4. Large-Scale System: 2.5km complex with substantial untested areas

5. Clear Development Path: Resource estimate targeted for Q1 2026

Market Context:

• Niobium demand growth driven by steel strengthening applications

• REE supply security critical for renewable energy technologies

• Brazil advantage as an established mining jurisdiction with infrastructure

The combination of surface-starting mineralisation, exceptional grades, and complete asset ownership creates a unique value proposition. In addition, these factors distinguish the project in the competitive critical minerals exploration landscape.
