American Lithium's Falchani pilot plant in Peru has achieved average lithium recovery of 88.7%, above the 80% assumed in its 2024 feasibility study, as the project's estimated capital cost rises to $834 million.
At a glance
- American Lithium's Falchani pilot plant in Peru averaged 88.7% lithium recovery in semi-continuous bench tests, above the 80% used in its 2024 feasibility study.
- The pilot plant also produced battery-grade lithium carbonate exceeding 99.5% purity from Falchani's volcanic-hosted ore.
- American Lithium's Peruvian subsidiary, Macusani Yellowcake, separately raised the project's estimated capital cost to $834 million.
Background
Falchani is a volcanic-hosted lithium deposit in southern Peru being developed by American Lithium through its local subsidiary, Macusani Yellowcake. A pilot plant tests a project's processing steps at a small scale before a full commercial plant is built, and its results are used to confirm or revise the recovery and cost assumptions in earlier feasibility studies.
What happened
American Lithium's Falchani pilot plant in Peru achieved average lithium extraction of 88.7% in bench-scale test work, in a range of 88.0% to 89.9%. That is above the 80.0% recovery rate used in the project's February 2024 feasibility study. The pilot process also produced battery-grade lithium carbonate exceeding 99.5% purity. Macusani Yellowcake, American Lithium's Peruvian subsidiary, separately raised the project's estimated capital cost to $834 million at the Expomina 2026 industry event.
Why it happened
Falchani's lithium sits in volcanic rock rather than the granite pegmatites or brine that supply most of the world's lithium. That gives its ore naturally low impurities, which let American Lithium simplify its processing steps. The company said lithium losses at each processing stage were cut to fractions of a percent. That is what drove the overall recovery rate above the project's earlier feasibility-study assumption. Higher confirmed recovery matters because those assumptions drive both a project's future revenue and its capital cost estimates.
What it means
Falchani is still a pre-construction project, so these results affect its future economics rather than near-term lithium supply. A validated flowsheet and a clearer cost estimate make it easier for American Lithium to raise construction financing later. For India, which imports nearly all its lithium, projects like Falchani add to a small pool of new sources outside China and South America's traditional brine producers.
Our read
Outlook: neutral. Falchani is a pre-construction project years from output, so its pilot-plant results affect American Lithium's own project economics rather than current lithium prices.
What to watch
- Whether American Lithium confirms the bench-scale recovery rate during three months of continuous pilot-plant operation.
- Updates to Falchani's feasibility study reflecting the higher recovery rate and the $834 million capex estimate.
- American Lithium's progress toward financing Falchani's construction phase.
