Initial Results Support Ceasium Development
Recent testwork at PMET Resources Inc.'s Shaakichiuwaanaan Project has revealed promising results in the production of caesium, indicating significant potential alongside other critical minerals like lithium and tantalum. The initial metallurgical test revealed a robust commercial-grade pollucite concentrate, suggesting a sustainable pathway for recovery.
Noteworthy Highlights of the Testwork
Among the primary findings is the successful production of a marketable grade pollucite concentrate from the Vega Caesium Zone, demonstrating:
- 11.9% Cs2O yield with an impressive 88% global recovery rate.
- Size fraction compositions include 20.0% Cs2O (12.5 to 25 mm) and 11.5% Cs2O (>25 mm).
- Concentrates exceeding 8-10% Cs2O are considered highly favorable for downstream applications.
X-Ray Transmission Ore Sorting Process
The application of X-Ray Transmission (XRT) ore sorting has proven advantageous in recovering caesium economically. The benefits include:
- A waterless process generating no tailings, thereby minimizing environmental impact by only producing coarse, dry reject material.
- Significant residual lithium and tantalum in reject materials can be further exploited using conventional methods.
The Scale of the Mineral Resource
The combined Rigel and Vega Zones classify as the largest known pollucite-hosted caesium pegmatite mineral resource globally, boasting:
- 693,000 tonnes at 4.40% Cs2O in indicated resources.
- 1,698,000 tonnes at 2.40% Cs2O in inferred resources.
Future Directions for PMET Resources
PMET is poised to advance on its findings, exploring further caesium recovery opportunities. A follow-up program aims to refine the XRT process while focusing on the extraction of lithium and tantalum. The company is engaging with potential end-users and supply chain participants to assess commercial viability.
Significance of Caesium
Caesium is one of the rarest minerals found in LCT pegmatite systems, foundational for several industrial applications, including pharmaceuticals and advanced materials for solar panels. Its supply is currently limited to a few historically operated mines, thereby presenting PMET with a unique opportunity to address this gap.
Understanding Market Potential
The caesium market operates differently from mainstream commodities, relying on bilateral contracts rather than public trading. Presently, caesium carbonate transactions reflect its importance and growing demand in sectors like energy and technology.
