Toronto, Ontario--(Newsfile Corp. - March 4, 2024) - First Lithium Minerals Corp. (CSE: FLM) (OTC Pink: FLMCF) (FSE: X28) ("First Lithium Minerals" or the "Company") is pleased to announce the receipt of a favorable official response to its "Consulta de Pertinencia de Ingreso al SEIA del Proyecto de Sondajes OCA" (the "Environmental Approval") for the upcoming drilling exploration program and signing of a Cooperation Agreement (the "Agreement") that formalizes the Company's relationship with The Cebollar-Ascotan Indigenous Community "Comunidad Indígena Cebollar-Ascotán" (the "Community") at the Salar de Ascotan, which forms Company's 100%-owned OCA project ("OCA Project") in the Antofagasta Region of northern Chile.

The Company received an official response from the Environmental Evaluation Service of Chile "Servicio de Evaluación Ambiental (SEA)", which states that the Company is not obliged to enter the Environmental Impact Assessment System "Sistema de Evaluación de Impacto Ambiental (SEIA)" to conduct its upcoming drilling program on the Company's exploration concessions at the salar de Ascotan. The northeastern property areas at the salar de Ascotan (approx. 1,775 ha) were previously identified as priority exploration drill targets following promising Transient Electromagnetic ("TEM") and Magneto-Telluric (MT) geophysical surveys. (Ref.: Press Release, March 24, 2023: "First Lithium Minerals Announces Drill Targets and Upcoming Exploration Program").

Upon the receipt of the Environmental Approval, the Company has entered into the Cooperation Agreement with the Cebollar-Ascotan Indigenous Community for the formation of a long-term mutually beneficial partnership for the Community to benefit from the participation in the employment opportunities and social infrastructure improvements.

First Lithium Minerals is dedicated to contributing to environmental sustainability and socio-economic health of the Community. The Agreement establishes provisions for information-sharing, monitoring, and environmental protection. The Community and the Company will oversee the Agreement's implementation and provide active site monitoring to protect the land and water in the project exploration area.

Rob Saltsman, CEO and Director of First Lithium Minerals, commented: "Securing environmental approval and signing the community agreement are important milestones that effectively make our project drill-ready. Through this Agreement, First Lithium Minerals is confirming its commitment and dedication to the environmental and socio-economic sustainability of the Cebollar-Ascotan Indigenous Community. We are extremely pleased to have signed this Agreement with the Community, which provides acknowledgement, consent, and support for our exploration activities, as we continue to advance the OCA project in an environmentally sustainable and responsible way with a full focus on a social license to operate."

The Company is currently in the process of selecting a qualified and experienced drilling contractor and conducting site visits for the drill program logistics and operational planning.
