Power Minerals Delivers Promising Santa Anna Rare Earth Results

Spectacular High-Grade Results Reveal World-Class Potential

The latest drilling results from Power Minerals' Santa Anna rare earth results have delivered exceptional high-grade rare earth element (REE) intersections that position the project as a potentially world-class asset in the critical minerals space.

The fourth hole (MN-TM-04) of the company's ongoing 1,000-meter auger drill program has returned truly remarkable results, including:

• 15m at 13,212ppm TREO (Total Rare Earth Oxides) from surface to end of hole
• 4m at 28,827ppm TREO from 9m
• 1m at 43,385ppm TREO (4.34%) from 11m

These results represent some of the highest-grade REE intersections reported at the Santa Anna Project to date, with the peak result of 4.34% TREO standing out as particularly significant within the global REE exploration landscape.

The mineralogical composition is also extremely favorable, with approximately 24-26% of the total rare earth content consisting of magnet rare earth oxides (MREO) – the most commercially valuable subset of rare earth elements essential for permanent magnets used in electric vehicles and renewable energy technologies.

Niobium Adds Significant Value Proposition

In addition to the exceptional REE results, the same drill hole returned impressive niobium values:

• 15m at 4,319ppm Nb₂O₅ from surface to end of hole
• 3m at 7,522ppm Nb₂O₅ from 11m
• 1m at 7,748ppm Nb₂O₅ from 12m

This dual mineralisation profile of both REE and niobium significantly enhances the economic potential of the Santa Anna Project, as niobium is a critical metal used in high-strength, low-alloy steels and superalloys for applications ranging from jet engines to superconducting magnets. Similar strategic partnerships for rare earth consortium in Kenya highlight the growing global interest in securing these critical resources.

Strategic Expansion of Mineralised Footprint

The current auger drilling program is designed to extend the Santa Anna Project's mineralised footprint to the east and south-east of initial drilling, targeting shallow niobium and REE in previously untested areas of the Santa Anna Alkaline Complex.

What makes these results particularly compelling is that all completed drill holes ended in mineralisation, suggesting strong potential for the mineralisation to continue at depth beyond the current drilling capacity of the auger program.

"The latest results from our ongoing auger drilling campaign at the Santa Anna Project provide further compelling validation of our exploration model at the Project, and in our confidence in its potential to deliver a significant Mineral Resources Estimate," said Managing Director Mena Habib.

Understanding Carbonatite-Hosted REE Deposits

What is a Carbonatite Complex?

Carbonatites are rare igneous rocks composed of more than 50% carbonate minerals, formed from unusual magmas that originate deep within the Earth's mantle. These geological formations are globally significant as they host some of the world's richest deposits of rare earth elements, niobium, and phosphate.

The Santa Anna Alkaline Complex, discovered only in 2021, represents a textbook example of this deposit type. Alkaline complexes typically have a core zone near their center, with surrounding zones that may host extensive local mineralisation – exactly what Power Minerals is confirming through its systematic exploration program.

What makes carbonatite deposits particularly valuable is their potential for large tonnage, relatively high-grade mineralisation that can often be economically extracted using relatively simple processing methods compared to other REE deposit types. This is similar to the promising results seen at Altair Minerals' copper project in Peru, where high-grade results are driving exploration momentum.

Project Timeline and Next Steps

Power Minerals has outlined a clear pathway forward for the Santa Anna Project:

1. Current Phase (Ongoing): Complete the 1,000m auger drilling program (approximately 60 holes) by September 2025
2. Near-Term Testing: Conduct leach tests using industry-standard AMSUL wash conditions to determine individual REE recoveries in the clay-rich portion
3. Follow-Up Drilling: Plan deeper RC drilling into fresh rock beneath the weathered zone
4. Resource Definition: Build toward a significant Mineral Resource Estimate (MRE)

The systematic approach to drilling, using a grid pattern, is specifically designed to assist with future Mineral Resource Estimate calculations – highlighting the company's confidence in the project's potential to advance rapidly toward resource definition.

Strategic Advantages of the Santa Anna Project

The Power Minerals Santa Anna rare earth results boast several significant strategic advantages that set it apart from many other REE exploration projects globally:

1. Complete Coverage: Power Minerals' tenements cover the entire Santa Anna Alkaline Complex, providing unparalleled exploration and development potential without boundary constraints
2. Mining-Friendly Jurisdiction: Located in Goiás State, a mining-friendly jurisdiction in Brazil with established infrastructure
3. No Environmental Concerns: The project has no known environmental issues or concerns
4. High-Grade, Near-Surface Mineralisation: The shallow nature of the mineralisation could potentially lead to favorable economics for any future mining operation
5. Critical Mineral Combination: The dual presence of both REE and niobium provides multiple potential revenue streams

In the current exploration landscape, companies with promising gold discovery projects like Inca Minerals are similarly positioned to capitalize on near-surface mineralisation with favorable economics.

Why Investors Should Follow Power Minerals

The exceptional Power Minerals Santa Anna rare earth results position the company as an emerging player in the critical minerals sector at a time when secure supplies of REEs and niobium are becoming increasingly strategic for governments and industries worldwide.

With each new drilling result, the company continues to build confidence toward achieving its near-term goal of confirming a significant Mineral Resource Estimate at the Santa Anna Project. The consistent high grades from near-surface indicate potential for a world-class exploration opportunity in the critical minerals sector.

For investors looking for exposure to the critical minerals thematic, Power Minerals represents a compelling opportunity with:

• A portfolio approach that includes lithium assets in Argentina and critical minerals in Brazil
• Exceptional grades of both REE and niobium at Santa Anna
• Clear pathway to resource definition
• Experienced management team with a track record of discovery
• Strategic positioning in the global critical minerals supply chain

As global demand for rare earth elements and niobium continues to grow, driven by the energy transition and technological advancement, Power Minerals appears well-positioned to capitalise on this high-growth sector with its flagship Santa Anna Project. Furthermore, strategic corporate moves similar to Inca Minerals' takeover of Stunalara demonstrate how companies are consolidating assets to strengthen their market position in the resources sector.

The project's potential aligns with broader industry trends where companies like Great Boulder Resources are identifying new targets that could deliver significant shareholder value through systematic exploration programs.
