CENTURY LITHIUM COMMENDS FIRST PHOSPHATE IN MAKING LFP BATTERY

CELLS USING CENTURY LITHIUM MATERIAL

July 8, 2025 – Vancouver, Canada – Century Lithium Corp. (TSXV: LCE) (OTCQX: CYDVF) (Frankfurt: C1Z)

(“Century Lithium” or “the Company”) congratulates First Phosphate Corp. (“First Phosphate”) (CSE: PHOS)

(OTCQB: FRSPF) (FSE: KD0) on successfully producing commercial-grade lithium iron phosphate (“LFP”)

18650 format battery cells, as reported in First Phosphate’s news release on July 7, 2025. The LFP cathode

and anode materials for the First Phosphate 18650 LFP battery cells were produced using North American

critical minerals, which included lithium carbonate derived from Century’s Angel Island and produced at

Century’s Demonstration Plant in Nevada, USA, as well as high-purity phosphoric acid and iron powder

from First Phosphate’s Bégin-Lamarche property in Quebec, Canada.

“Century Lithium is very pleased that First Phosphate found our lithium carbonate suitable for use in

producing LFP battery cells,” said Bill Willoughby, Century Lithium President and CEO. “Century Lithium

continues to advance Angel Island through permitting, engineering, and innovation at the Company’s

Demonstration Plant in Nevada. We see a bright future for lithium-based chemistries. We believe LFP

batteries, in particular, will have an important place in the future of mobile and stationary energy storage

systems. We look forward to continuing to support First Phosphate as we work together to strengthen the

North American supply chain.”

The LFP 18650 battery cells were assembled for First Phosphate by Ultion Technologies Inc. at their pilot

facility in Las Vegas, Nevada.

combined with direct lithium extraction to make battery-grade lithium carbonate product samples from

Angel Island’s lithium-bearing claystone on-site at its Demonstration Plant in Amargosa Valley, Nevada.

Angel Island is one of the few advanced lithium projects in development in the United States to provide an

end-to-end process to produce battery-grade lithium carbonate for the growing electric vehicle and

battery storage market. Angel Island is currently in the permitting stage for a three-phase feasibility-level

production plan expected to yield an estimated life-of-mine average of 34,000 tonnes per year of

carbonate over a 40-year mine-life.
