- This discovery could be a game-changer for critical mineral supply, especially for new tech like advanced solar panels.
Ready to dive a bit deeper into what this all means for the future of essential minerals?
How Did Shaakichiuwaanaan Achieve High Recovery Caesium Concentrate?
PMET Resources Inc. just hit a major milestone at its Shaakichiuwaanaan Project by successfully creating marketable, commercial-grade pollucite concentrates. This happened during their initial bench-scale tests on material from the Vega Caesium Zone at the CV13 Pegmatite.
The results were seriously impressive: they achieved an average of 11.9% Cs2O with an 88% global recovery. To put that in perspective, a pollucite concentrate of 8-10% Cs2O is already considered highly valuable for industrial use. This shows just how high-quality and commercially viable the caesium at Shaakichiuwaanaan’s CV13 Deposit truly is.
This success isn’t just about caesium, though. It also sets a clear path to make caesium a valuable co-product alongside lithium and tantalum. This multi-mineral approach boosts the entire project’s economic potential, turning it into a vital source for several critical minerals.
What is XRT Ore Sorting, and How Does it Help Recover Caesium?
The secret sauce behind this metallurgical success is a technology called X-Ray Transmission (XRT) ore sorting. Think of XRT ore sorting as a smart scanner for rocks. It’s a well-known and commercially proven dry mechanical process used widely in mining, especially for larger pieces of crushed material.
Here’s how it works for pollucite recovery:
- It scans material to analyze its atomic density.
- Using a blast of compressed air, it precisely separates the denser pollucite pieces into a concentrate.
- Lighter, less dense materials are rejected.
One of the coolest things about XRT ore sorting at the Shaakichiuwaanaan Project is how eco-friendly and efficient it is. There’s no need for water or chemicals, which means no messy tailings ponds, just dry reject material. Plus, it only requires a coarse crush of the ore, skipping the energy-intensive grinding steps often found in traditional methods. This makes XRT an incredibly simple, cost-effective, and sustainable way to produce caesium concentrate.
Can Shaakichiuwaanaan Recover Lithium and Tantalum Alongside Caesium?
Absolutely! The potential of the Shaakichiuwaanaan Project isn’t limited to its impressive caesium concentrate production. During the XRT ore sorting tests, they discovered that the leftover material from the CV13 Pegmatite still held significant amounts of other valuable critical minerals: lithium (as spodumene) and tantalum (as tantalite). This opens up exciting possibilities for creating multiple revenue streams from a single mining operation.
The best part? The rejected material from the XRT sorter is perfectly sized for subsequent recovery of these additional minerals using standard, established methods. Lithium-rich spodumene can be processed using Dense Media Separation (DMS), a common technique in lithium mining. Tantalum can then be recovered from the rejects using simpler gravity and magnetic separation methods. This integrated approach is super appealing because the pollucite XRT ore sorting recovery circuit can easily be added before the spodumene DMS circuit, keeping the overall process straightforward and efficient. This smart processing pathway significantly boosts the project’s economics, making PMET Resources Inc. a key player in a diversified critical mineral supply chain.
Why is Shaakichiuwaanaan’s CV13 Deposit Considered a World Leader in Caesium Resources?
The amount of caesium found at Shaakichiuwaanaan is truly remarkable, setting a new global standard. The Rigel and Vega Zones at the project’s CV13 Deposit together represent the largest known pollucite-hosted caesium pegmatite Mineral Resource anywhere in the world. That’s a huge deal and highlights just how strategically important this discovery is.
The updated Mineral Resource Estimate (MRE), dated June 20, 2025, shows substantial resources:
- Indicated: 693,000 tonnes at 4.40% Cs2O, 2.12% Li2O, and 283 ppm Ta2O5.
- Inferred: 1,698,000 tonnes at 2.40% Cs2O, 1.81% Li2O, and 245 ppm Ta2O5.
To give you some context, pollucite deposits are usually quite small, often less than 350 kilotonnes. Shaakichiuwaanaan’s indicated and inferred resources blow these typical figures out of the water, cementing its unique position as a significant global source of caesium. This massive resource base gives PMET Resources Inc. a strong foundation for long-term production and a dominant presence in the evolving caesium market.
Why is Caesium So Important, and What Are Its Emerging Uses?
Caesium is a highly reactive alkali metal that’s absolutely vital for various high-tech and industrial uses. Historically, pollucite-hosted caesium deposits have been incredibly rare, serving as virtually the only economic source of the mineral. With previous major mines depleting their resources, the market has faced a significant caesium supply constraint.
While the caesium market is a bit hush-hush, operating mainly through private contracts, its importance is growing. Caesium carbonate (Cs2CO3≥99%) currently trades around US$155/kg. Beyond its traditional roles in oil/gas drilling fluids and medical imaging, caesium is now becoming a star in exciting new applications. For example, it dramatically improves the efficiency, stability, and lifespan of next-generation solar panels through its use in perovskite crystal structures. A discovery of this size and grade at Shaakichiuwaanaan’s CV13 Pegmatite has the potential to become a primary, long-term global source, helping to bridge supply gaps and power innovations in renewable energy.
What Are the Next Steps for Developing the Shaakichiuwaanaan Project?
PMET Resources Inc. isn’t resting on its laurels; they’re actively pushing the Shaakichiuwaanaan Project forward with a clear strategy to get the most out of its critical minerals. They’re planning more testwork to fine-tune the XRT circuit for even better pollucite recovery. This involves collecting larger drill core samples to explore different size fractions, aiming to perfect the processing pathway based on the already fantastic initial results.
At the same time, they’re refining the software that directs the ore sorter to specifically match the unique characteristics of Shaakichiuwaanaan’s CV13 pollucite pegmatite, which should further boost separation efficiency.
And it’s not just about caesium! A dedicated program is underway to recover the spodumene (lithium) and tantalite (tantalum) from the ore sorter reject materials using simple gravity and magnetic methods. The company is also exploring how to integrate the caesium opportunity at Rigel and Vega as a future co-product, engaging with potential end-users and supply chain partners. While a feasibility study for the CV5 Mineral Resource (focused on lithium) is nearing completion, the economic potential of these critical metal co-products (caesium and tantalum) will be assessed through separate, ongoing studies. This comprehensive approach ensures a bright future for this globally significant critical mineral deposit.
