FIRST LITHIUM MINERALS RECEIVES ENVIRONMENTAL APPROVAL AND SIGNS COOPERATION AGREEMENT WITH THE CEBOLLAR-ASCOTAN INDIGENOUS COMMUNITY

First Lithium Minerals Corp. has received a favourable official response to its "Consulta de Pertinencia de Ingreso al SEIA del Proyecto de Sondajes OCA" (the environmental approval) for the coming drilling exploration program and signed a co-operation agreement that formalizes the company's relationship with the Cebollar-Ascotan indigenous community at the Salar de Ascotan, which forms the company's 100-per-cent-owned OCA project in the Antofagasta region of northern Chile.

The company received an official response from the environmental evaluation service of Chile, Servicio de Evaluacion Ambiental (SEA), which states that the company is not obliged to enter the environmental impact assessment system, Sistema de Evaluacion de Impacto Ambiental (SEIA), to conduct its coming drilling program on the company's exploration concessions at the Salar de Ascotan. The northeastern property areas at the salar de Ascotan (approximately 1,775 hectares) were previously identified as priority exploration drill targets following promising transient electromagnetic (TEM) and magnetotelluric (MT) geophysical surveys.

Upon the receipt of the environmental approval, the company has entered into the co-operation 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, chief executive officer 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 acknowledgment, 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 licence 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.
