Peruvian Supreme Court Mandates Full Company Ownership of Disputed Claims

Legal & Disputes

VANCOUVER, BRITISH COLUMBIA, December 03, 2025 – American Lithium Corp. (“American Lithium” or

the “Company”) (TSX-V:LI | OTCQX:AMLIF | Frankfurt:5LA1) reports that its Peruvian subsidiary, Macusani

Yellowcake S.A.C., has been notified of Resolution No. 24 issued by the Sixth Permanent Court of Lima,

which definitively consolidates the legal security of the 32 mining concessions subject to the judicial

process.

The Court has ordered the enforcement of the final judgment, after the higher court declared inadmissible

the cassation appeals filed by the co-defendants, INGEMMET and the Ministry of Energy and Mines. The

final ruling restores the validity and ownership of the 32 mining concessions in favour of Macusani

Yellowcake S.A.C. This constitutes a key milestone for the Falchani and Macusani projects.

The Court requires INGEMMET to issue, within a maximum period of 30 days, a new administrative

resolution fully reflecting the judgment, under penalty of fines in case of non-compliance, and to correctly

official (full name/address/office) charged with complying with the mandate. Failure to do so will result

in the highest institutional authority being deemed responsible under functional liability.

The process is now in the judgment -enforcement stage, with all possible appeals exhausted. This grants

the project a framework of full legal stability, essential for the development and continuity of present and

future investments related to the project.

Alex Tsakumis, Interim CEO of American Lithium, commented: “This Supreme Court Order provides the

final legal clarity we have been seeking. The Court has not only reaffirmed Macusani’s position, but has

also ordered immediate administrative compliance, giving us a clear runway to advance two of the most

strategically important critical-minerals projects in the Americas.”

This ruling is a major de-risking event for American Lithium, securing the Company’s concession rights at

the highest judicial level in Peru and eliminating remaining sources of potential delay. With full restoration

of the titles now mandated, the Company can move forward with Falchani, its large-scale lithium and

cesium critical-minerals project, and with Macusani, one of the world’s largest undeveloped uranium de-

posits, with enhanced legal security. With this confirmation, the Company is positioned to continue tech-

nical work, permitting processes, and strategic development across all its critical minerals assets.
