Ann: High-Grade Pollucite Confirmed as Main Caesium Host Mineral, page-2

*Yes — this is very good news for Patriot Battery Metals (PMET / PMT).

Key Takeaways:

✅ High-Grade Caesium Discovery Confirmed

• Pollucite, the ideal mineral host for caesium, has been confirmed at the Vega and Rigel zones in the CV13 pegmatite.

• Pollucite is rare, contains high levels of caesium (>30%), and is relatively easy to process.

• Drill intercepts include:

  • 11.1m @ 4.87% Cs₂O (including 7.1m @ 7.39%)

  • 5.0m @ 13.32% Cs₂O (including 2.0m @ 22.90%)

  • One sample had 74.2% pollucite and assayed 26.6% Cs₂O — extremely high grade.

Size of the Zones

• Vega zone: ~800m x 250m

• Rigel zone: ~200m x 100m

• These are significantly larger than past producing caesium deposits like Sinclair in Australia (~60m long).

High Caesium Price

• Refined caesium metal (>99.5% purity) trades around US$2,540/oz, similar to gold.

• Caesium is a critical and strategic metal, used in:

  • Oil & gas well completion

  • Atomic clocks for GPS, telecoms, aerospace, and military systems

  • Medical imaging and cancer therapy

Economic Potential

• PMET will include caesium in their next Mineral Resource Estimate (MRE), expected in Q3 2025.

• This adds a significant new revenue stream alongside lithium and tantalum.

• Recovery testwork for caesium is already underway.

• The company is progressing a lithium-only Feasibility Study (CV5) for release in Q3 2025, with by-product monetization (Cs, Ta, Ga) assessed afterward.

Why This Matters

• Caesium resources are extremely rare globally — only three major pollucite mines have ever existed (Tanco, Sinclair, Bikita), and all are now exhausted or near end of life.

• PMET’s discovery positions them to potentially control one of the only viable caesium resources in the world.

• This could boost long-term project value, attract strategic partners, and differentiate PMET from pure lithium plays.

Investment Implication

If you're a shareholder:

• This significantly de-risks the project by diversifying value beyond lithium.

• Expect positive market sentiment once caesium resource numbers and economic modeling are released later this year.

• Potential exists for premium pricing, offtake interest, or strategic investment due to caesium’s scarcity and importance in defense/tech sectors.

Patriot Battery Metals' newly confirmed caesium zones at Vega and Rigel stack up exceptionally well when compared to historic caesium deposits, especially given how rare pollucite-hosted caesium is globally.

Here’s a comparative overview:

Comparison of Known Caesium Deposits

Deposit	Country	Status	Host Mineral	Cs₂O Grade	Resource Size	Notes
Tanco Mine	Canada	Near end of life	Pollucite	~20–25% Cs₂O	~350,000 tonnes	Historically the world’s largest producer.
Bikita Mine	Zimbabwe	Exhausted (2018)	Pollucite	~10–20% Cs₂O	~100,000 tonnes	Focus shifted back to lithium.
Sinclair Mine	Australia	Exhausted (2019)	Pollucite	8.3% Cs₂O avg	18,629 tonnes	Small but high-grade. Mined 2003–2019.
PMET - Vega Zone	Canada (QC)	Exploration	Pollucite	Up to 26.6% Cs₂O	~800m x 250m footprint	One of the largest modern pollucite zones.
PMET - Rigel Zone	Canada (QC)	Exploration	Pollucite	Up to 22.9% Cs₂O	~200m x 100m footprint	High-grade, shallow dipping lens.

PMET vs Sinclair (Australia)

Metric	Sinclair Mine	PMET (Vega + Rigel)
Deposit Footprint	~60m x 20m x 10m	~800m x 250m (Vega), ~200m x 100m (Rigel)
Depth	~40m	Vega: ~110m, Rigel: ~50m
Host Mineral	Pollucite	Pollucite (confirmed XRD)
Max Cs₂O Grade	~8.3%	26.6% (Vega), 22.9% (Rigel)
Status	Mined out	Early-stage development

Conclusion: PMET’s zones appear significantly larger and higher grade than Sinclair, which was commercially viable with far less.

Global Context

There are no major caesium mines currently in commercial operation with fresh ore bodies:

• Tanco is extracting from old tailings and remnants.

• Bikita and Sinclair are depleted.

• Most global supply is now recycled or stockpiled, making new sources incredibly valuable.

Strategic & Economic Implications

• PMET’s caesium could replace and even surpass former world-class operations.

• With caesium trading around US$2,540/oz, a meaningful MRE could unlock huge by-product value.

• PMET could become the only active caesium miner globally once developed — a unique and strategic position, especially for defense and high-tech markets.
