TORONTO, Dec. 15, 2025 – Statement by CEO Mirco Wojnarowicz on Ontario’s Critical Minerals Processing Fund

Rock Tech Lithium Inc. (“Rock Tech” or the “Company”) welcomes the Province of Ontario’s approval and launch of the CAD $500 million Critical Minerals Processing Fund (“CMPF”), a milestone initiative designed to accelerate the province’s critical minerals processing capacity and strengthen Ontario’s position in the global battery materials supply chain.

Rock Tech’s proposed Lithium Conversion Facility (the “Converter”) in Red Rock, Ontario directly aligns with the CMPF’s mandate to support midstream critical minerals processing projects in the province. The Converter is designed to deliver domestic lithium conversion capacity for battery-grade products, reduce reliance on offshore processing, and anchor downstream investment in Ontario’s electric vehicle and energy storage supply chain.

The CMPF represents a clear signal to global markets that Ontario is committed to scaling up processing capacity needed to support the energy transition. By enabling new critical mineral projects and midstream processing facilities, the fund will help catalyze investment, create jobs, and anchor long-term economic benefits across the province.

As a technology company advancing its Georgia Lake lithium mining project and a lithium conversion facility in Ontario, located only about 60 kilometers apart, Rock Tech sees the CMPF as an important building block in establishing a regional and integrated lithium battery supply chain. The planned design of the Converter in Red Rock is directly based on Rock Tech’s fully permitted, shovel-ready converter in Guben, Germany, which was recently designated an EU Strategic Project under the European Critical Raw Materials Act (CRMA). This foundation gives the Converter a uniquely advanced and de-risked design — positioning it as one of the most technically mature lithium conversion projects in North America.

“We applaud the Government of Ontario for taking bold action to support critical minerals development,” said Mirco Wojnarowicz, CEO of Rock Tech Lithium. “With the CMPF now approved, Ontario is sending a clear signal that it intends to lead in battery materials. Our Converter in Red Rock, built on the engineering and experience behind our EU CRMA Strategic Project in Germany, is exceptionally well-positioned to help deliver the processing capacity the province needs to compete globally.”

Rock Tech has invested more than 350,000 engineering hours and CAD 65 million into the design of its lithium conversion facilities. The Company will continue to work closely with provincial partners, Indigenous communities, and industry stakeholders to support the development of an integrated, competitive, and resilient lithium supply chain in Ontario.
