Sedgman and North American Lithium: design-phase insights for project engineers
Reviewed by Tom Sullivan
First reported on International Mining – News
30 Second Briefing
Sedgman, part of CIMIC Group and ACS Group’s global critical minerals platform, is advancing the expansion of Sayona and Piedmont Lithium’s North American Lithium (NAL) operation in Québec through an ongoing feasibility study and a newly awarded detailed design mandate. The work follows updated scoping and prefeasibility studies for the NAL spodumene concentrator and associated processing facilities, targeting higher throughput and improved lithium recovery. For engineers, the key shift is from concept-level options to executable design, locking in flowsheet, plant layout and infrastructure requirements for the next growth phase.
Technical Brief
- Feasibility-level work typically refines comminution and flotation equipment sizing, structural loads and foundation requirements.
Our Take
Sedgman’s work at the North American Lithium (NAL) operation in Québec gives CIMIC Group another foothold in battery minerals, complementing its processing contracts in base metals such as zinc and silver at Hindustan Zinc’s Rampura Agucha mine.
Lithium appears in over 100 items in our database, but relatively few are tied to Canadian projects, so NAL stands out as one of the more prominent Québec-based entries in current project and contract-award coverage.
With CIMIC Group consolidating ownership of Thiess Group in a separate move, the NAL contract suggests the parent is positioning its mining and processing arms to capture more of the lithium value chain alongside its traditional coal and metals portfolio.
