The merger between Allkem and Livent has triggered one of the most important processing transformations in the global lithium industry. At the core of this shift is the large-scale industrialisation of direct lithium extraction (DLE) across Argentina’s Hombre Muerto basin, combining Allkem’s Sal de Vida project in Catamarca with Livent’s Hombre Muerto South expansion in Salta. The integrated strategy is designed to bypass the structural limits of evaporation ponds, accelerate project timelines, and improve overall resource efficiency.
Sal de Vida is advancing as a multi-phase lithium development, with total CAPEX for Phases 1 and 2 estimated at USD 1.6–1.8 billion. Investment spans brine extraction fields, DLE adsorption units, lithium carbonate conversion, power infrastructure, and water management systems. Ownership under the merged Allkem–Livent platform allows early-stage construction to be funded from the corporate balance sheet, while retaining the option to introduce project-level debt once operating data validates performance.
Hombre Muerto South: Leveraging Operational History
The Hombre Muerto South expansion complements Sal de Vida with incremental CAPEX of approximately USD 600–700 million, primarily focused on DLE modules and downstream chemical processing integrated into Livent’s existing facilities. Livent’s decades-long operating presence in the salar significantly reduces geological and resource risk, shifting the key execution challenge toward process efficiency, reagent optimisation, and long-term adsorption stability.
Financing across both assets is being sequenced conservatively. Early phases rely on internal cash flow and equity, while senior debt is expected to fund up to 45 percent of later expansion capital once recovery rates and operational uptime are demonstrated at scale. Lenders are underwriting against conservative lithium price assumptions, placing covenant emphasis on water balance, adsorption cycle performance, and system reliability, rather than nominal production capacity.
Economics and Environmental Advantages of DLE
From an economic standpoint, DLE improves lithium recoveries and dramatically reduces land use and water intensity compared with traditional evaporation-based processing. These structural advantages support EBITDA margins above 40 percent under mid-cycle pricing scenarios. The merged platform’s scale further enables procurement synergies in reagents, power contracting, and maintenance, lowering unit operating costs across both projects.
For investors, the strategic importance of Sal de Vida and Hombre Muerto South lies in execution credibility. If both projects achieve stable, repeatable performance, DLE will shift from a niche solution to an industrial standard in Argentina, reshaping capital allocation, project design, and environmental benchmarks across the broader Lithium Triangle.
