Frontier Lithium Inc. announce the commencement of the first phase of the Definitive Feasibility Study (DFS) for the PAK lithium project ("Project") and the award of the mine and mill scope to DRA Americas Inc., a fully-owned subsidiary of DRA Global (DRA). DRA Global is an international multi-disciplinary engineering, project delivery, and operations management group primarily focused on the mining, minerals, and metals industry. Following the encouraging results from the Company's Preliminary Feasibility Study (PFS) on the Project, as described in the press release dated July 17,2023.

The Company is excited to be moving forward with the next stage of project engineering. The fully integrated mine, mill, and refinery flowsheet demonstrated in the PFS will be studied in two distinct scopes at the DFS level with the mine and mill scope set to conclude in the next 12-18 months. It is projected that a mine and milling facility with an estimated output of 200,000 metric tonnes of spodumene concentrate per annum will be brought online in two stages: Stage 1 ­ Winter Road Access: The existing winter road will be used for the construction of the first concentrator line targeting the high purity PAK deposit and facilitating the production of up to 100,000 metric tonnes per annum of premium spodumene concentrates.

Stage 1 aims to leverage the winter road for transportation to market to facilitate rapid market penetration with the Company's premium spodumene concentrates. Stage 2 ­ All Season Road Access: The development and ramping of the second mill line into production will be completed concurrent with the targeted completion of an all-season access- road to the region. This expansion will enable the export of additional premium spodumene concentrates, to enhance Frontier's market presence.

Implementing this phased construction approach serves to mitigate project risks, capitalize on existing infrastructure, and focuses the Company on short-term concentrate production goals. Additionally, this strategy will aim to minimize potential delays associated with all-season road construction, and to provide a more streamlined path with options for operational success. Frontier remains fully financed for the successful completion of the Phase 1 DFS, reinforcing its commitment to driving sustainable lithium solutions in the Canadian mining industry.
