High-Grade Gold Results Strengthen Power Minerals Santa Anna Project

Power Minerals Strikes High-Grade Gold with Exceptional Niobium and REE Results at Santa Anna

Power Minerals Limited (ASX: PNN) has delivered another round of impressive drilling results from its expanding Santa Anna carbonatite project in Brazil. The high-grade gold results from Power Minerals' systematic 1,000-metre shallow drilling campaign have returned multiple high-grade intersections over 86.5 metres, building strong momentum toward the planned maiden Resource Estimate in Q1 2026.

The standout results from holes 20-25 include 16m at 4,462 ppm TREO from surface in hole MN-TM-020, featuring a spectacular 2m at 12,261ppm (1.23%) TREO from 1 metre depth. Furthermore, these results are complemented by strong niobium grades, with hole MN-TM-022 delivering 7m at 2,221 ppm Nb2O5 from 5m, including 2m at 3,226 ppm Nb2O5 from 9m.

Key Investment Highlights:

• Consistent high-grade results across expanding drill programme
• 10,000m RC drilling campaign set to commence this month
• Complete ownership of entire alkaline carbonatite complex
• Q1 2026 target for maiden Mineral Resource Estimate

Exceptional Continuity Builds Resource Confidence

The latest batch of results from Power's ongoing auger drilling programme demonstrates remarkable consistency in both grade and continuity across the shallow weathered zone. Hole MN-TM-021, located just 86 metres east of the previously reported high-grade hole MN-TM-18, returned 15m at 5,686 ppm TREO from surface, including 7m at 8,429 ppm TREO and 2m at 13,034 ppm (1.30%) TREO.

This spatial consistency is particularly significant for resource definition, as it confirms the continuity of the REE-enriched phase of the carbonatite complex. Moreover, the systematic grid-based drilling approach on 80-metre spacing is methodically mapping the extent and grade distribution across previously untested areas of the large alkaline complex.

In addition, the niobium results are equally impressive, with multiple intersections exceeding 2,000 ppm Nb2O5, including the standout 4m at 2,725 ppm Nb2O5 with 2m at 3,340 ppm Nb2O5 in hole MN-TM-023.

Understanding Carbonatite Complexes: A Critical Minerals Treasure Trove

Carbonatite complexes represent some of the world's most significant sources of critical minerals, particularly rare earth elements and niobium. These unique geological formations are carbonate-rich igneous rocks that typically contain elevated concentrations of REE, niobium, phosphorus, and other critical elements essential for modern technology.

Why Carbonatites Matter for Investors:

• Primary global source of niobium and many rare earth elements
• Typically large-tonnage deposits with consistent grade distribution
• Simple mineralogy often leads to more straightforward processing
• Strategic importance for battery metals and high-tech applications

However, the Santa Anna complex benefits from intense tropical weathering, which has concentrated the valuable minerals in a shallow, clay-rich layer extending to depths of 15 metres. This weathering process often enhances the grades and creates oxidised mineralogy that can be more amenable to extraction compared to fresh rock carbonatites.

Major Drilling Campaign Set to Accelerate Resource Definition

Power Minerals is preparing to launch its most significant drilling programme to date, with a 10,000-metre reverse circulation (RC) campaign designed to rapidly expand the known mineralised footprint. The first phase of 2,000 metres is scheduled to commence this month, targeting the Nb-rich phases of the carbonatite complex to the southeast of current drilling.

Strategic Drilling Objectives:

• Extend mineralised footprint east and southeast of maiden drilling
• Target deeper portions of the carbonatite complex
• Test untested zones within the 1,705-hectare project area
• Generate data for maiden Mineral Resource Estimate

Consequently, this systematic approach builds on Power's maiden 29-hole, 2,272-metre RC programme completed in June 2025, which first identified the exceptional grades and established the foundation for the current success. The combination of shallow auger drilling for near-surface definition and deeper RC drilling for resource expansion represents a comprehensive exploration strategy.

Managing Director Insight:
"The continuing 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." – Mena Habib

Why Investors Should Follow Power Minerals

Power Minerals has positioned itself strategically in the critical minerals sector through its complete ownership of the Santa Anna alkaline carbonatite complex, discovered as recently as 2021. With the high-grade gold results from Power Minerals consistently showing exceptional grades across an expanding drill database and systematic exploration methodology, the company is rapidly advancing toward a significant resource definition.

For instance, the combination of niobium and rare earth elements in a single deposit provides portfolio diversification within the critical minerals space, reducing dependency on any single commodity. Both elements are essential for renewable energy infrastructure, advanced manufacturing, and defence applications, positioning Santa Anna as a potentially strategic asset.

Investment Tracking Points:

• Q1 2026 maiden Resource Estimate represents key near-term catalyst
• Complete project ownership eliminates joint venture complexities
• Proven exploration model with consistent results across growing dataset
• Strategic location in established mining jurisdiction of Brazil
• Management team with demonstrated execution capability

What Makes This Discovery Exceptional?

The high-grade gold results from Power Minerals at Santa Anna are particularly noteworthy due to several key factors. The weathered zone extends from surface to approximately 15 metres depth, creating an optimal mining scenario with minimal overburden requirements.

Furthermore, the mineralisation demonstrates remarkable consistency across the tested area, with seventeen of the twenty-five holes returning significant intersections. This hit rate of 68% provides strong confidence in the continuity of mineralisation across the project area.

Future Exploration Potential

The Santa Anna complex covers 1,705 hectares, with current drilling having tested only a small portion of this substantial landholding. The upcoming 10,000-metre RC drilling programme will systematically test multiple target areas, potentially expanding the known mineralised footprint significantly.

Additionally, the project's location in Minas Gerais state provides access to established mining infrastructure and a skilled workforce, reducing potential development risks. The Brazilian regulatory environment offers a stable framework for mineral exploration and development activities.

With the Santa Anna project representing an advanced high-grade critical minerals exploration opportunity and systematic drilling continuing to validate the exceptional grades and continuity, Power Minerals has established itself as a compelling growth story in the critical minerals sector. The approaching major drilling campaign and targeted Q1 2026 Resource Estimate provide clear near-term catalysts for continued investor attention.

Key Takeaway:
Power Minerals has systematically built an exceptional critical minerals asset at Santa Anna, with consistent high-grade results across both niobium and rare earth elements. The upcoming 10,000-metre drilling campaign and targeted Q1 2026 Resource Estimate position this as a must-watch story in the critical minerals space.
