Mexico’s lithium: when ambition meets political reality
*Please note that this report only includes an Excel data file if this is indicated in "What's included" below
Report summary
Mexico’s bid to become a global lithium player remains stalled by political caution, legal limits, and unproven technology. Since nationalising the mineral in 2022 and creating the state operator LitioMx, the country has declared vast reserve zones—most notably in Sonora—yet production is still theoretical. Unlike South American brine-rich salars, Mexico’s lithium is trapped in clay deposits that require costly, energy‑intensive processing, and no commercial extraction method has succeeded so far. The government is now exploring an alternative path: “petrolithium” from oilfield and geothermal brines, with early data from the Sureste Basin showing promising lithium concentrations. Three years on, Mexico’s lithium story remains rich in potential but short on output.
