PRESS RELEASE

CRITICAL ELEMENTS LITHIUM SUMMER EXPLORATION PLANS

May 12th, 202 5 - MONTRÉAL, QUÉBEC – Critical Elements Lithium Corporation (TSX -V: CRE) (US

OTCQX: CRECF) (FSE: F12) ( "Critical Elements" or the "Corporation”) is pleased to announce the

recommencement of active exploration on its highly prospective, 1,050 square kilometre land portfolio ,

including the 100% owned Nemaska Belt properties.

An important helicopter-borne electromagnetic VTEM plus time-domain system (“VTEM”) survey covering

the Nemaska Belt group of properties in the Eeyou Istchee region of Québec has been completed (Figure

1). The 2,701-line kilometre VTEM survey executed by Geotech Airborne Geophysical Survey covers the

entirety of Critical Elements’ 100%-owned Nemaska Belt properties with flight lines at a 200-metre spacing.

The objective of the survey was to identify conductors that could correlate with high-grade Nickel-Copper-

PGE mineralization and define high-priority drill targets.

The Corporation plans to begin a surface exploration program on the Nemaska Belt portion of the portfolio

and the Rose blocks at the end of May and intends to pursue a prospecting, mapping, and sampling

program until late August. Dahrouge Geological Consulting L td. (“Dahrouge”) has been mandated to

perform the summer exploration program targeting potentially economic mineralization including high-grade

Nickel-Copper-PGE as well as lithium-bearing spodumene.

Management continues to be engaged in assembling the funding required to make a final investment

decision on the Corporation’s flagship Rose Lithium-Tantalum project. These efforts build on the $20 million

conditional funding from Natural Resources Canada’s Critical Minerals Infrastructure Fund (see press

release dated February 6, 2025) and the support letter from a leading Canadian financial institution stating

its interest in providing long term debt financing of up to US$115 million (approximately C$150 million) of

project debt (see press release dated February 10, 2025).
