Frontier Lithium Inc. (TSX-V: FL) (FRA: HL2) (OTCQX: LITOF) is pleased to announce its receipt of $2 million in grant funding from the Northern Ontario Heritage Fund Corporation to test the processing and conversion of by-products as it advances towards commercial lithium salts production.

The funding announced today at the future headquarters of Frontier, by Ontario Premier, Doug Ford, Minister of Northern Development and Indigenous Affairs, Greg Rickford, Minister of Mines, George Pirie, and Minister of Economic Development, Job Creation and Trade, Vic Fedeli reflects the importance of the fully integrated PAK Lithium Project to EV and EV battery supply chains in the province. The NOHFC grant will enable the construction of a facility that will demonstrate processes targeted at the conversion of sodium sulfate by-products to achieve a closed-loop system for lithium salt production. This testing is expected to lead to reagent input regeneration, process optimization, recycling, energy efficiency and waste minimization that will mitigate disposal risks associated with by-products.

This new grant builds on NOHFC funding received by Frontier in 2021 to test the production of lithium hydroxide, an important component of the lithium-ion battery. The findings from the 2021 tests have informed this next phase of the research process and reflects Frontier’s desire to seek and implement environmentally responsible solutions to advance commercial lithium production objectives in Ontario.

About Frontier Lithium

Frontier Lithium Inc. is an exploration and development mining company with headquarters and assets in Northern Ontario, a tier-one mining jurisdiction. The Company’s PAK Project represents the largest proven land position in a new, premium lithium mineral district, with a 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 largest in Ontario 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 PAK deposit within the project claims). A 2023 Pre-Feasibility Study titled “”National Instrument 43-101 Technical Report PFS PAK Lithium Project”” authored by BBA E&C Inc., delivered a 24- year project life, at a post-tax NPV(8%) of US$1.74 billion and internal rate of return of 24.1% as per the press release disseminated on May 31, 2023 , and was filed on www.SedarPlus.com.
