On August 2st, Sydney-listed Elevra Lithium has secured a price-floor supply agreement to deliver spodumene concentrate from its Québec project to Mangrove Lithium's planned conversion facility in Canada, as North American players move to build out domestic lithium processing capacity.
Under the agreement, Elevra will supply 100% of the feedstock required for Mangrove's 20,000 tonne-per-year lithium carbonate-equivalent conversion plant. The deal includes a price floor set above Elevra's expected production cost, with no ceiling on the upside, though the contract value was not disclosed. The Mangrove facility remains subject to a final investment decision, with additional funding support expected from Export Development Canada and the Canada Growth Fund, according to Mangrove Chief Commercial and Strategy Officer Annie Liu.
Liu noted that floor-price offtake structures are becoming increasingly standard across the hard-rock lithium supply chain, citing long asset development lead times and sustained demand for spodumene feedstock. A similar structure was adopted in February when Australia's PLS Group signed a floor-priced spodumene concentrate offtake agreement with a Chinese converter.
SMM View: The Elevra-Mangrove agreement reflects growing use of price-floor mechanisms to underpin new spodumene supply contracts, providing upstream producers with cost-cover certainty against continued lithium price volatility while securing dedicated feedstock for new North American conversion capacity. As more western processing projects reach final investment decision, similar floor-price offtake structures may become a standard feature of non-China-aligned spodumene supply chains, with implications for how feedstock is contracted and priced globally.
