Siemens Canada to Build Digital Twin of Rock Tech's Ontario Lithium Converter

Rock Tech Lithium has signed agreements with Siemens Canada covering the Red Rock Lithium Converter, the lithium conversion plant Rock Tech plans to build in Ontario with capacity for up to 32,000 tonnes per year of lithium carbonate equivalent. Siemens will develop a digital process twin of the plant and support Rock Tech’s project team on the converter’s definitive feasibility study (DFS).

Rock Tech describes the twin as a virtual, physics-based model of the plant’s processes, energy flows and material streams that lets the company test, optimize and validate design choices, efficiency, emissions and operational reliability before major capital is committed. The first step is a digital process twin built on results from the DFS. The company plans for the technology to cover the project’s entire lifecycle, from the feasibility study through engineering and construction to operations.

The agreements are the first implementation phase under a memorandum of understanding the two companies signed in March 2026. That memorandum covers development and integration of Siemens digital twin technology, as well as evaluation of additional Siemens solutions, services and engineering support. Rock Tech says the goal is to position the Red Rock Converter as a blueprint for future converters in Canada and allied markets. The parties will also evaluate applying the cooperation to future projects in other G7 countries.

In Canada, Rock Tech’s feedstock sources include its wholly owned Georgia Lake Project. In July 2026, the company secured an option to acquire the Victory project, a lithium exploration property in Northwestern Ontario.

For the DFS, Siemens Canada will provide support in process control, instrumentation and automation architecture. Rock Tech launched the study at the end of June 2026 and expects to finalize it by mid-December 2026.
