Sibanye-Stillwater Starts Talks with EU on Ensuring Keliber’s Viability

Why It Matters

The refinery would create Europe’s only integrated lithium supply chain, cutting dependence on China and bolstering the EU’s strategic minerals agenda.

Key Takeaways

• Keliber refinery cost €763 m (~$832 m) pending price‑support decision.
• Project profitable above $13,000/ton; current price $24,000/ton.
• EU talks aim for floor price or protection for Keliber.
• Only integrated European lithium project, critical for EU battery supply.

Pulse Analysis

The lithium market has entered a new phase of volatility, driven by soaring demand for electric‑vehicle batteries and energy‑storage systems while Chinese producers still dominate refined output. Prices for lithium hydroxide, the key feedstock for high‑performance batteries, have swung from below $10,000 per tonne to over $24,000 per tonne within a year. This turbulence has prompted governments, especially the European Union, to reconsider how they secure critical mineral supplies, leading to the Industrial Accelerator Act and discussions about floor‑price guarantees for strategic projects.

Keliber, owned by Sibanye‑Stillwater, represents a rare European‑based, vertically integrated lithium operation. The first two phases—a €763 million open‑pit mine and a concentrator—are on schedule, with mining already underway and the concentrator in hot commissioning. Economic modeling shows the project breaks even at $13,000 per tonne of lithium hydroxide, a threshold comfortably above the current $24,000 level. However, the third phase—a refinery—remains a financial gamble; a price dip back below $10,000 would render it uneconomic, forcing a costly shutdown. The company’s leadership is therefore seeking EU‑backed price‑support tools to de‑risk the refinery investment and protect shareholders.

If the EU delivers tailored support—such as a floor price, early‑stage subsidies, or guaranteed offtake for the refined product—Keliber could become the cornerstone of a European battery supply chain. That would reduce the bloc’s reliance on Chinese refined lithium, align with “Made in the EU” objectives, and create a strategic asset for both regional manufacturers and global automakers. Conversely, without such guarantees, the project may stall, leaving Europe vulnerable to supply shocks and missing an opportunity to establish a domestic source of a critical clean‑energy input.
