FRONTIER LITHIUM INC. AWARDS CONTRACT FOR DEFINITIVE FEASIBILITY STUDY FOR THE PAK LITHIUM PROJECT

Frontier Lithium Inc. has started the first phase of the definitive feasibility study (DFS) for the PAK lithium project and has awarded the mine and mill scope to DRA Americas Inc., a fully owned subsidiary of DRA Global (DRA). DRA Global is an international multidisciplinary 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 to 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.

About Frontier Lithium Inc.

Frontier Lithium is an exploration and development mining company with headquarters and assets in Northern Ontario, a Tier 1 mining jurisdiction. The company's PAK project represents the largest land position in a new, premium lithium mineral district, with a proven high-grade, large tonnage and pure lithium resource. Strategically located in Ontario's Great Lakes region near the United States border, Frontier is developing the first fully integrated lithium mining-and-processing operation in Ontario with an aim is to become a significant supplier of spodumene concentrates and battery-grade lithium hydroxide to the growing electric vehicle and energy storage markets across North America.

About the PAK lithium project

The Pak lithium project contains North America's highest-grade lithium resource and is the second largest in North America by size. The project encompasses close to 27,000 hectares and remains largely unexplored; however, since 2013, the company has delineated two premium spodumene-bearing lithium deposits (Pak and Spark), located 2.3 kilometres apart. Exploration is continuing on the project through two other spodumene-bearing discoveries: the Bolt pegmatite (located between the Pak and Spark deposits) as well as the Pennock pegmatite (25 kilometres northwest of the Pak deposit within the project claims). A 2023 prefeasibility study, "National Instrument 43-101 Technical Report PFS PAK Lithium Project," by BBA E&C Inc. delivered a 24-year project life, delivering a posttax net present value (discounted at 8 per cent) of $1.74-billion (U.S.) and internal rate of return of 24.1 per cent, as per the press release disseminated on May 31, 2023, and was filed on SEDAR+.
