New Pathways for Battery-Grade Lithium Carbonate from Shaakichiuwaanaan Project

Recent advancements in lithium processing at PMET Resources Inc.'s Shaakichiuwaanaan project in Quebec, Canada, indicate promising opportunities for producing battery-grade lithium carbonate directly at the mining site. A completed concept study analyzed processing methods for converting spodumene concentrate into higher-value lithium products, achieving a notable purity level of 99.8% Li₂CO₃.

Overview of the Study

The study embarked on a systematic review of various processing flowsheets, ultimately identifying the proprietary ALi® atmospheric leach process from Primero, a subsidiary of NRW Holdings, as the most economically suitable option. This method not only addresses technical concerns but also aligns with both PMET's sustainability objectives and the environmental goals of Canada and Quebec regarding domestic mineral processing.

Bench-scale tests have shown that the ALi® process, which operates at lower temperatures and pressures, results in a significantly reduced carbon footprint compared to traditional methods. By leveraging Quebec’s low-cost renewable hydroelectric power for electric calcination, the processing initiatives aim to decrease logistics intensity and further the development of a sustainable local battery materials supply chain.

Enhanced Economic Potential

Frederic Mercier-Langevin, Chief Operations/Development Officer at PMET, highlighted that Shaakichiuwaanaan is already a Tier-1 asset recognized in a prior feasibility study from 2025. The newly identified refining pathway could enhance the project's overall value by enabling on-site production of battery-grade lithium chemical, thereby generating cost savings and minimizing environmental impacts.

"It's time for the industry to reconsider how lithium is processed. Traditionally, lithium is mined in one location and refined elsewhere, which complicates the supply chain. This study opens possibilities for redefining these processes," said Mercier-Langevin.

If implemented, this on-site processing strategy could also support Quebec's critical mineral strategies by producing value-added products domestically, thus reducing dependency on offshore refining services.

Future Work and Developments

With this concept study in hand, PMET anticipates conducting further evaluations to optimize the ALi® process. This includes additional testing to enhance product recovery rates and delineating logistical efficiencies.

As a long-term growth strategy, this initiative aims to establish a robust domestic lithium supply chain that caters to both North American and European markets. By focusing on producing concentrated lithium chemicals directly at the mine site, PMET can realize substantial logistical cost savings and facilitate a more sustainable extraction-to-processing model.

In summary, the concept study presents a transformative approach to lithium processing that could significantly benefit both PMET Resources and the broader North American lithium market. The findings encourage a future where Canadian geological advantages are fully utilized to supply an increasing global demand for lithium at a lower carbon cost, ultimately supporting the development of electric vehicles and renewable technologies.

Conclusion

With ongoing progress and subsequent detailed studies planned, the Shaakichiuwaanaan project positions itself at the forefront of sustainable lithium production. As developments unfold, PMET continues to pave the way towards a cleaner, more efficient lithium supply chain that not only meets market demands but also upholds the principles of environmental stewardship.
