FCL Showcases FCL-X™ Lithium Battery Fire Extinguishing Products at Fire Leadership Challenge in Keystone, Colorado

TORONTO, Oct. 23, 2025 /PRNewswire/ - Full Circle Lithium Corp. ("FCL" or the "Company") (TSXV: FCLI) (OTCQB: FCLIF), a US-based lithium-ion battery fire products manufacturer, is proud to participate in the 2025 Fire Leadership Challenge in Keystone, Colorado. Through one of FCL's new representation agreements with SHUR-SALES & Marketing Inc., the company will be featuring its industry-leading FCL-X™ lithium battery fire extinguishing products to key fire service leaders, emergency management officials, and public safety stakeholders in Colorado.

Lithium-ion battery fires are a rapidly growing threat as electric vehicles, E-mobility, energy storage systems, and portable electronics become more widespread. These fires are uniquely dangerous — capable of triggering violent thermal runaway events, re-ignitions, and toxic off-gassing. They are difficult to extinguish using conventional fire suppression methods.

"We were honored to be invited to this year's Fire Leadership Challenge and to be part of the national dialogue around this urgent issue," said Chad Carver, VP Sales and Operations at FCL. "There's no question: lithium battery fires are here, they are serious, and they are increasing. Departments need tools now. That's why we developed FCL-X™ — and it's proving to be the best solution available."

FCL-X™ is a purpose-built extinguishing agent formulated specifically to neutralize and suppress lithium-ion battery fires quickly, effectively, and safely. Unlike water or general-purpose suppressants, FCL-X™ is designed to target battery chemistry and prevent reignition. Already trusted in the field, one of Colorado's fire departments is a current user of FCL-X™ and continues to rely on it in frontline response scenarios involving electric vehicles and mobile energy storage.

"Having a progressive fire agency in Colorado already using FCL-X™ gives us real operational insight and validation," added Shane Bentley, Sales Director at FCL.  "We are seeing growing demand from departments that know conventional methods are not enough — and they want the best, field-ready solution today, not tomorrow."

The Fire Leadership Challenge offered FCLI the opportunity to:

• Engage directly with fire chiefs and emergency planners
• Demonstrate FCL-X™ performance capabilities
• Support the fire service community with education and real-world application knowledge

FCL remains committed to equipping fire professionals, fleet operators, and industrial safety leaders with the most advanced tools to manage the battery fire risks reshaping their environments.
