Full Circle Lithium's FCL-X™ Extinguishes Lithium Battery Fires at Fort McMurray Oil Industry Demonstration

About this update from Full Circle Lithium Corp

TORONTO, June 8, 2026 /CNW/ - Full Circle Lithium Corp. ("FCL" or the "Company") (TSXV: FCLI; OTCQB: FCLIF, FSE: K0Q's ), a leading U.S.-based manufacturer of lithium-ion battery fire extinguishing products, is pleased to announce today the resounding success of its live lithium battery burn demonstration held late May in Fort McMurray, Alberta. The event, attended by representatives of major oilsands producers, national railway, local fire departments, and health and safety professionals, showcased FCL's FCL-X™ suppression systems — the only technology in the world proven to quickly and completely extinguish lithium battery fires across a wide spectrum of battery types used in heavy industry. The Fort McMurray region sits at the heart of Canada's oilsands industry, home to some of the world's largest and most capital-intensive industrial operations. Lithium-ion batteries have become indispensable to daily site operations — powering everything from autonomous heavy machinery, haul trucks, and mobile equipment to mission-critical backup power systems and remote monitoring infrastructure. With that integration comes extraordinary risk. A single thermal runaway event on a large-format industrial battery can escalate within seconds, releasing toxic gases, including hydrogen fluoride (HF), carbon monoxide (CO), and methane 1, threatening lives, destroying equipment, and triggering regulatory shutdowns with multi-million-dollar consequences. A Demonstration That Left No DoubtDuring the live demonstration, FCL ignited lithium-ion batteries representing multiple chemistries and form factors commonly deployed across oilsands operations and backup power configuration battery arrays. In each case, FCL-X™ achieved rapid, full suppression — halting thermal runaway, eliminating re-ignition risk, and neutralizing toxic gas emissions — with a speed and efficiency that left attending operators and fire service professionals visibly impressed. Unlike conventional suppression approaches — which are largely ineffective against lithium battery fires and can require tens of thousands of litres of water over many hours(2) — FCL-X™ works through a proprietary chemical mechanism that directly interrupts the electrochemical chain reaction at the core of thermal runaway. The result: fires that traditional suppression systems cannot cont...
