Albemarle Backs Power Metals' Case Lake Project With Non-Dilutive Funding, Advancing North American Cesium Production

• Global chemicals powerhouse Albemarle delivers non-dilutive investment
• Exceptional grades and simple processing position Case Lake as a standout
• Production momentum grows with strong permitting progress
• Strong Indigenous support with Apitipi Anicinapek Nation signing Participation Agreement
• Development underway of Impacts Benefits Agreement with Apitipi Anicinapek Nation

VANCOUVER, BC, Dec. 16, 2025 /CNW/ - Power Metals Corp ("Power Metals" or the "Company") (TSXV:PWM) (FRANKFURT: OAA1) (OTCQB:PWRMF) is pleased to announce a Company update for the Case Lake Project ("the Project") in Ontario, Canada.

Power Metals Corp (TSXV:PWM) is entering a pivotal new phase as the Case Lake Cesium Project advances toward production. The momentum is being driven by strong technical progress, strengthened partnerships and a landmark agreement with one of the world's leading critical-minerals companies.

The recent pre-payment and offtake agreement with Albemarle (NYSE:ALB) has reshaped the trajectory of the Project, providing both validation and a clear pathway toward development.

This partnership brings global chemical expertise directly into the fold, while securing a non-dilutive source of funding that supports the next stage of work on site.

With up to C$5 million in funding available through staged payments tied to permitting milestones, the Project now has enhanced financial certainty as it moves toward construction.

Equally important is what this agreement signals for North America. Case Lake is emerging at a time when global cesium supply is rapidly diminishing, and market participants are seeking reliable, transparent and politically aligned sources of critical minerals.

Albemarle's involvement underscores Case Lake's potential to anchor a rebuilt North American cesium ecosystem – one that can serve high-value technologies without reliance on overseas refining.

On the ground, the Company continues to make strong progress across technical, permitting and community partnership milestones. Recent laboratory test work has reaffirmed the Project's ability to produce a clean, high-grade cesium concentrate through a simple, dry and chemical-free process.

This flowsheet not only reduces development complexity but also avoids tailings, providing a meaningful environmental advantage and helping to streamline the permitting pathway.

At the same time, geological work continues to strengthen the scale potential of the deposit.
