FRONTIER ADVANCES LITHIUM CONVERSION FACILITY WITH DEFINITIVE FEASIBILITY STUDY AWARD

MWN-AI** Summary

Frontier Lithium Inc. (TSXV: FL) has announced the launch of a Definitive Feasibility Study (DFS) for its lithium conversion facility in Thunder Bay, Ontario. This crucial step follows the positive results of a previous DFS focused on the company's mine and mill operations. The new study aims to assess a refinery that will utilize lithium produced by Frontier alongside potential third-party feedstock.

To conduct the DFS, Frontier has engaged Fluor Canada Ltd., a renowned engineering and construction firm, known for its expertise in critical minerals development. Fluor's responsibilities will cover a variety of components, including infrastructure planning, process design, cost estimation, and environmental assessments, all essential for enabling the first commercial lithium refining facility in Canada.

The objective of the feasibility study is to provide a preliminary capital cost estimate and establish a long-term production strategy for the refinement of lithium hydroxide and carbonate. This production capacity is projected to support the battery production needs for up to 500,000 electric vehicles annually, thereby positioning Canada as a vital player in the global battery supply chain.

Frontier Lithium emphasizes its commitment to sustainable resource development and collaboration with Indigenous communities and government bodies to successfully advance this significant project. With plans to complete the DFS within the next 18 months, Frontier also aims to finalize contribution agreements with federal and provincial governments in 2025/2026, further solidifying its role in the North American lithium market.

As a pioneer in lithium production, Frontier continues to leverage its strategic alliances—most notably with Mitsubishi Corporation in the PAK Lithium Project—to establish a robust and secure domestic lithium supply for the clean energy transition.

MWN-AI** Analysis

Frontier Lithium Inc. (TSXV: FL) has recently taken a pivotal step in establishing itself as a key player in Canada’s lithium supply chain by initiating a Definitive Feasibility Study (DFS) for its lithium conversion facility in Thunder Bay, Ontario. The decision to collaborate with Fluor Canada Ltd., a well-regarded engineering firm, indicates Frontier’s commitment to executing a comprehensive and strategically significant project.

From an investment perspective, this development is promising for several reasons. The completion of the DFS will provide crucial insights into the facility’s capital costs and economic viability, potentially leading to government funding agreements that can bolster liquidity and financial stability. With the global electric vehicle market projected to expand significantly, the proposed output of approximately 20,000 tonnes of lithium carbonate equivalent annually is well-positioned to meet increasing demand, which could support battery production for about 500,000 electric vehicles per year.

Moreover, Frontier's PAK Lithium Project, situated in a resource-rich area, is gaining traction due to its strategic joint venture with Mitsubishi Corporation. The DFS’s favorable findings could enhance investor confidence and create upward momentum for the stock price, given the projected after-tax net present value of CA$932 million.

However, potential investors must remain mindful of inherent risks as indicated in the company's forward-looking statements. Factors such as fluctuating market prices, regulatory challenges, and overall infrastructural development could impact the feasibility and profitability of the project.

In summary, while the commencement of the DFS signals positive growth potential for Frontier Lithium, investors should conduct thorough due diligence and consider market dynamics before making investment decisions. A balanced view that includes both the exciting prospects of the lithium market and the associated risks will be essential for capitalizing on opportunities in this sector.

GREATER SUDBURY, ON , July 31, 2025 /CNW/ - Frontier Lithium Inc. (TSXV: FL) (OTCQX: LITOF) ("Frontier" or the "Company") is pleased to announce the commencement of the Definitive Feasibility Study ("DFS") for the lithium conversion facility (the "Project") in Thunder Bay, Ontario . As a second definitive feasibility study, this work builds on the positive outcomes of the recently completed mine and mill DFS, with a dedicated focus on evaluating a refinery supplied by Frontier Lithium's own production and potential third-party feedstock. The Company has awarded the feasibility scope for the Project to Fluor Canada Ltd. ("Fluor"), a leading engineering and construction company that provides engineering, procurement, construction, maintenance, and project management services across various industries.

Fluor will work with Frontier to deliver the comprehensive DFS, covering various work packages such as infrastructure, process and design, cost estimation, economic valuation, procurement and a technical report for Frontier. Fluor will also advance execution planning, and coordination with specialized consultants supporting technical studies, reporting, and environmental assessments.

"After a thorough evaluation process, we have selected Fluor based on their global and North American expertise in critical minerals development and their proven track record delivering large-scale lithium processing and refinery projects," said Trevor Walker , President and Chief Executive Officer of Frontier. "Advancing this phase of the Project is critical not only for Frontier, but for ensuring that we continue to build a successful made-in-Canada EV battery supply chain. We're confident in the lithium refining experience of our project team and excited to move forward into this next phase".

The DFS will initially deliver a preliminary capital cost estimate laying the foundation for Frontier's first commercial refining facility and long-term production strategy. These outcomes will also support the goal of finalizing the contribution agreement's with both federal and provincial governments as previously announced in the Company's press release on March 4, 2025 and highlighted in the Province of Ontario budget on May 15, 2025 . Frontier expects to complete the federal and provincial government agreements in 2025/2026 and deliver the feasibility study within the next 18 months. Frontier may consider future updates to reflect integrated economics of the mine and mill and refinery projects, subject to funding progress.

The proposed Project, which is planned for the recently acquired Mission Island site (Figure A) in Thunder Bay, Ontario , will be designed to produce approximately 20,000 tonnes of lithium carbonate equivalent (LCE) lithium hydroxide salts annually, once in production. This output could support battery production for up to 500,000 electric vehicles per year. The Project will also be designed to accommodate supply from other lithium deposits both in Canada and internationally, strengthening Canada's role in the global battery supply chain.

Frontier remains committed to sustainable resource development and to working collaboratively with Indigenous community partners, stakeholders, and government agencies to ensure the successful execution of this nationally significant critical minerals project in Thunder Bay, Ontario .
