Argentina Lithium & Energy Corp. Files Technical Report for the Rincon West Lithium Project

Executive Summary

• Argentina Lithium filed a NI 43‑101 Technical Report disclosing the first MRE for the Rincon West lithium‑brine project, with measured and indicated resources of 212,800 t LCE (Lithium Carbonate Equivalent) and 1.47 M t KCl (Potassium Chloride).
• The report also details inferred resources totaling an additional 64,000 t LCE and 327,000 t KCl, highlighting the project's overall scale and potential.
• The filing re‑affirms Stellantis’ strategic investment (19.9% stake) and a seven‑year off‑take agreement for up to 15,000 t of lithium carbonate per year once commercial production commences.

Key Details

• Technical Report: “Mineral Resource Estimate – Rincon West Project, Salta, Argentina,” effective November 27 2025; available on SEDAR+ and the company website.
• Qualified Person: Frederik Reidel, CPG (Atacama Water Consultants).
• Resource Summary – Measured & Indicated (M + Ind):
• Lithium: 212,800 t LCE (Measured) + 26,600 t LCE (Indicated) = 239,400 t LCE.
• Potassium: 1,470,700 t KCl (Measured) + 175,720 t KCl (Indicated) = 1,646,420 t KCl.
• Inferred Resources: 64,000 t LCE and 327,000 t KCl.
• Aquifer & Brine Volumes: Total aquifer volume 4.33 km³; brine volume 0.15 km³ (Measured + Indicated).
• Grades & Concentrations: Mean lithium grade 11.9 g/m³ (Measured) and 4.9 g/m³ (Indicated); mean potassium grade 229.2 g/m³ (Measured) and 94.0 g/m³ (Indicated).
• Conversion Factors: Li → Li₂CO₃ = 5.32; K → KCl = 1.91.
• Stellantis Investment & Off‑take (Sept 2023):
• Stellantis, via Peugeot Citroën Argentina S.A., holds a 19.9% equity stake with an exchange right to convert shares into up to 19.9% of Argentina Lithium’s common stock.
• Seven‑year lithium off‑take right for up to 15,000 t Li₂CO₃ per year upon commercial production, with extension options and first‑refusal rights on surplus product.
• Cautionary Statements: Resources are NI 43‑101 compliant but not mineral reserves; inferred resources are conceptual and require further drilling and pump testing for upgrade.
