FRONTIER LITHIUM ANNOUNCES THIRD QUARTER RESULTS AND PARTICIPATION IN INDUSTRY EVENTS

Frontier Lithium Inc. has provided an update on its recent and upcoming participation in key industry events, and has released its third quarter financial results.

Frontier recently participated in the Precious Metals & Critical Minerals Virtual Investor Conference, a live, interactive on-line investor event, where the company presented to a broad audience of individual and institutional investors and engaged one-on-one with market participants.

The company attended the 35th Annual BMO Global Metals, Mining & Critical Minerals Conference in Hollywood, Fla., from Feb. 22, 2026, to Feb. 25, 2026. Frontier met with investors, partners and industry professionals. Discussions emphasized that critical minerals are now viewed as a national security issue, with access to capital being the main challenge rather than geology. The U.S. government signalled openness to investing in global projects supporting American supply chains. Lithium sentiment was positive, driven by demand for energy storage and concerns over reliance on Chinese supply.

Frontier Lithium was also pleased to participate in the recent Canadian Critical Minerals Investment Forum hosted by Natural Resources Canada and Invest in Canada. Engagements were held across Rome, Munich and Paris joining Canadian critical mineral mining peers to showcase the company's projects and to strengthen collaboration with European governments, investors and industrial partners. In all engagements, discussions advanced co-operation under bilateral critical minerals frameworks and the G7 Alliance on the Production of Critical Minerals, reinforcing a shared commitment to standards-based markets and responsible development and explore new partnerships across strategic sectors. Across all forums, Frontier showcased its investment-ready lithium assets and reaffirmed its commitment to safe, sustainable and long-term development in support of resilient North American and European battery supply chains.

In addition, Frontier will be attending the Prospectors & Developers Association of Canada (PDAC) 2026 Convention, taking place between March 1, 2026, and March 4, 2026, at the Metro Toronto Convention Centre (MTCC) in Toronto, Ont., Canada, the world's premier mineral exploration and mining event, bringing together global industry leaders, investors, governments and service providers. Frontier will be exhibiting at booth No. 3236 in the Investors Exchange and scheduled to deliver a corporate presentation as part of PDAC's Electric Materials 2 session on Tuesday, March 3, 2026, from 3:30 p.m. in Room 801B at the MTCC, highlighting its project developments and investment story to an audience of investors and industry participants

The company also reports the filing of its interim financial results for the third quarter ended Dec. 31, 2025. Frontier closed the quarter with $12-million in cash and cash equivalents, supporting continued project advancement and corporate activities. The quarter and subsequent period reflect continued execution across key work streams, including consultation activities under Ontario's One Project, One Process (1P1P) framework and strengthened engagement with local first nations, culminating in the execution of formal process agreements in January, 2026, with Deer Lake and Sandy Lake first nations to advance collaborative permitting for the company's PAK project. Earlier in the quarter, the PAK project was selected as Ontario's first lithium project under the 1P1P framework, helping streamline the provincial permitting pathway. Frontier also continued advancing refinery predefinitive feasibility study work with its engineering partner, including value engineering initiatives across the mine and mill flowsheet, and released an independent socioeconomic impact study highlighting the project's significant economic, employment and regional benefits. Most recently, the company welcomed the announcement of the start of construction of the Berens bridge and road project by Ministry of Northern Economic Development and Growth. Collectively, these milestones demonstrate measurable progress toward derisking and advancing the PAK project.

Frontier's condensed interim consolidated financial statements and accompanying management's discussion and analysis for the three-month period ended Dec. 31, 2025, have been filed on SEDAR+ and can be viewed under the company's website.

About Frontier Lithium Inc.

Frontier Lithium is a preproduction mining company with an objective to become a strategic and integrated supplier of premium spodumene concentrates, as well as battery-grade lithium salts to the growing electric vehicle, and energy storage markets in North America. The company's PAK lithium project maintains the largest land position and resource in a premium lithium mineral district located in Ontario's Great Lakes region.

About the PAK lithium project

The PAK lithium project is a fully integrated critical minerals initiative in Ontario, developing a high-grade, large-scale lithium resource. Operated as a joint venture between Frontier (92.5 per cent) and Mitsubishi Corp. (7.5 per cent), the project is advancing in parallel with a mine and mill, north of Red Lake, Ont., and a downstream lithium conversion facility in Thunder Bay, Ont., which are both key to supporting a secure domestic lithium supply for the clean energy transition. A 2025 mine and mill feasibility study (FS), prepared by DRA Global Ltd. and entitled "National Instrument 43-101 Technical Report FS PAK Lithium Project, Mine and Mill," outlines a 31-year project life with an after-tax net present value of $932-million at a discount rate of 8 per cent and an after-tax internal rate of return of 17.9 per cent. These results have been disclosed in the company's news release dated May 28, 2025, and the accompanying technical report was filed on SEDAR+ on July 9, 2025.
