Argentina held meaningful stocks across oil, gas, and coal, which gave it flexibility across global energy markets. Reserve estimates had been revised upward over the past decade, reflecting new discoveries or improved recovery technology.
Argentina produces Lithium and Gold among USGS-tracked critical minerals.
USGS marks 2025 production figures and all reserve estimates as estimated; some earlier production years are USGS estimates as well. Each commodity below charts its own mine-production history, with the 2025 reserve shown beneath its chart.
