Rock Tech Lithium has announced a strategic shift to develop an integrated mine-to-converter lithium supply chain in Canada, leveraging its engineering expertise built in Germany. The company plans to combine its 100%-owned Georgia Lake spodumene mine in Ontario with the Red Rock Converter facility, located just 70 kilometers away. This integrated approach aims to capture value at both the mining and conversion stages while reducing exposure to volatile spot feedstock markets.
Georgia Lake’s economics have been further enhanced by recent ore-sorting test results conducted in collaboration with Queen’s University and STARK Resources. Preliminary data indicate a 25–45% reduction in waste, a 1.4–1.8× increase in feed grade, up to a 50% cut in capital requirements for crushing and concentration, and roughly 20% lower operating costs. Rock Tech plans a summer 2026 drill program to expand inferred resources, with a definitive feasibility study (DFS) award targeted for August 2026 and first production expected about 18 months after a planned final investment decision (FID) in the first quarter of 2027.
The Red Rock Converter will use the engineering blueprint from Rock Tech’s fully permitted Guben project in Germany but will benefit from Canada’s supportive policy environment. The federal and Ontario governments have committed co-investment through the Canada Strong Fund, treating critical minerals as strategic assets. Ontario hydroelectric power priced competitively adds another advantage. Rock Tech has structured Red Rock as a general-partner/limited-partner (GP/LP) joint venture, retaining operational control and technology royalties while strategic and financial partners provide most project capital. Anchor investors include BMI Group and potential equity participation from Siemens Canada, with both federal and provincial funding discussions underway. A DFS award for Red Rock is expected in June 2026, aiming for FID in early 2027.
Rock Tech will also maintain its Guben converter in Germany as a fully engineered asset under the same GP/LP model, pursuing strategic partnerships and potential sales to realize value. To broaden its investor base, the company has launched a XETRA listing and is preparing a NASDAQ application, timing a US listing around Red Rock’s FID.
