On Friday, Elevra Lithium's stock price rose as much as 6.1% after the company signed a supply agreement with Mangrove Lithium.
The agreement covers spodumene concentrate from Elevra's Quebec project. Elevra will provide the entire feedstock for the planned 20,000-ton-per-year lithium carbonate conversion facility.
What sets this deal apart is the pricing structure. For Elevra, the floor price means it can count on a minimum return above production costs in a market that has been volatile. For Mangrove, the deal locks in a steady supply for a plant that has not yet been built.
Additional support from Export Development Canada and the Canada Growth Fund, along with other partners, is expected to follow once the project is formally approved. That support matters because building new lithium processing capacity is expensive and slow. A floor price helps both sides plan around that cost. Elevra knows it will not lose money on every ton it sells, and Mangrove knows it has a guaranteed supplier.

This is not just one company making a deal. It is part of a broader push across Western economies to build lithium processing capacity and reduce dependence on Chinese supply chains.
A broader shift is visible in this deal, said Annie Liu, a Mangrove Lithium executive. "The trend is very clear that all regions would like to preserve and secure their national security on critical minerals," Liu said. She added that "downstream processing is the key step in building an 'offshore-from-China' supply chain."
The February deal between Australia's PLS Group and another company, which also included a floor price, shows this is not a one-off. Liu expects the structure to catch on. "We do expect this type of pricing structure to be the standard moving forward," she said.
The lithium market has seen sharp swings in recent years, with prices falling from record highs as supply outpaced demand. That volatility makes long-term contracts with price floors especially useful for miners like Elevra, which must justify large capital costs for new projects. The Quebec project is still in development, and Mangrove's plant has not yet been approved, so both sides are betting that this pricing structure will give them enough certainty to proceed.
Mangrove's planned facility would process 20,000 tons of lithium carbonate per year, and Elevra would be its sole feedstock supplier. That makes the deal central to Mangrove's plan to build downstream processing outside China.
In the past year, Elevra's shares have more than doubled. Friday's rally is one part of that larger story. The deal gives investors a clearer view of what the company can earn even in a weak lithium market.
The floor price protects Elevra from a drop below costs, while Mangrove secures the supply it needs to become a Western alternative to Chinese processing. Mangrove's plant still needs financing from groups like Export Development Canada, a final construction go-ahead, and a long build-out.
But the pricing structure creates a shared incentive for both sides. In a lithium market full of uncertainty, that is rare: a deal where the producer and the offtaker both have clear reasons to make it work.
