PMET Advances On-Site Lithium Refining Strategy Through Technology Collaboration MOU with Mitsui and MWCC

By

PMET Resources (PMET.TO) after the close Wednesday said entered into a non-binding memorandum of understanding with Mitsui & Co., Ltd. and Microwave Chemical Co., Ltd. to jointly evaluate the application of proprietary microwave calcination technology to spodumene samples from its Shaakichiuwaanaan project in the Eeyou Istchee James Bay region of Quebec.

According to the statement, microwave calcination has the potential to support electric calcination at site, which is the first step in the production of value-added lithium chemicals from spodumene concentrate, leveraging Quebec's low-cost, renewable hydroelectric power as a potential alternative to conventional fossil fuel-based calcination.

Calcination is an initial processing step in the conversion of spodumene concentrate into downstream lithium chemicals, using heat to convert alpha-spodumene into beta-spodumene for subsequent lithium extraction. Historically, fossil fuels have been the key energy source to create heat and the overall energy required to undertake the phase change.

"This collaboration is a direct extension of the downstream growth strategy we outlined recently for Shaakichiuwaanaan. Our concept study identified a potential pathway to produce battery-grade lithium carbonate on site, and microwave calcination now represents an opportunity to evaluate one of the key enabling technologies that could support that vision," chief executive Ken Brinsden said. "Shaakichiuwaanaan is already one of the world's premier hard-rock lithium projects, and the collaboration with Mitsui and Microwave Chemical represents another important step in our strategy to evaluate additional value-creation opportunities beyond spodumene concentrate."

PMET shares closed down $0.16 to $6.19 on Toronto Stock Exchange.

Lundin Mining (LUN) on Tuesday said Vicuna Corp., a joint venture with BHP Group (BHP) received approval for the inclusion of the Josemaria and Filo del Sol deposits to the Incentive Regime for Large Investments under the Long-Term Strategic Export Projects (RIGI PEELP) designation in Argentina.Vicuna is the first copper mining project in Argentina to be granted the more favourable RIGI PEELP status, it added.Lundin chief executive Jack Lundin, said: "We are very pleased to receive this favourable ruling which represents a significant milestone for the Project. The approval of Vicuna's RIGI PEELP application is an important step forward in advancing one of the world's most important copper districts. Argentina's RIGI regime is designed to attract and accelerate large-scale investment through long-term fiscal stability and transparent regulatory conditions. Under this regime, the Project will benefit from greater investment certainty, further supporting progress toward a final investment decision for Stage 1 before the end of this year. Together with our partner, BHP, we appreciate the constructive engagement and support of the Governments of Argentina and San Juan and look forward to continuing to work collaboratively to unlock the full potential of Vicuna for the benefit of all stakeholders."Lundin noted development of the Vicuna district is envisioned in a staged approach. Stage 1 encompasses a sulphide mill and the Josemaria deposit, the technical report released on February 16, 2026 estimated an initial capital at $7.1 billion. The RIGI PEELP application capital expenditure number included stage 1 and aspects of Stage 2 (leachable oxides).Lundin shares closed up $1.40 to $41.25 on the Toronto Stock Exchange.
