Euro Manganese signs offtake term sheet with 6K Energy

Term sheet supports EMN's project development as a secure, traceable Western source of high-purity manganese for North American battery supply chains

Vancouver, British Columbia--(Newsfile Corp. - August 17, 2026) - Euro Manganese Inc. (TSXV: EMN) (ASX: EMN) (OTC Pink: EUMNF) (FSE: E060) (the "Company" or "Euro Manganese" or "EMN") is pleased to announce that it has entered into a non-binding offtake term sheet with 6K Energy, a leading U.S.-based producer of advanced cathode active materials ("CAM"), for the proposed sale of high-purity electrolytic manganese metal ("HPEMM") from the Company's Chvaletice Manganese Project ("Chvaletice" or the "Project") in the Czech Republic.

The term sheet follows 6K Energy's successful testing and preliminary qualification of high-purity manganese produced at Euro Manganese's Demonstration Plant. This technical milestone provides important customer validation of the material's quality and suitability for advanced battery-material applications.

The proposed offtake represents an important step in establishing Chvaletice as a secure and traceable source of high-purity manganese for North American battery and advanced-manufacturing supply chains. Euro Manganese and 6K Energy have also agreed to evaluate broader opportunities involving the Company's products and their potential use within 6K Energy's business.

Highlights

6K Energy has successfully tested and preliminarily qualified high-purity manganese produced at Euro Manganese's Demonstration Plant, providing third-party validation of its quality and suitability for advanced battery-material applications.

The term sheet contemplates a long-term, take-or-pay offtake arrangement, with pricing and other commercial terms intended to support the Project's debt-financing requirements.

Initial volumes of HPEMM are expected to be supplied from Euro Manganese's Demonstration Plant beginning in 2028, supporting continued qualification and commercial engagement ahead of first commercial production.

The pricing structure contemplated by the term sheet is designed to support the Project's anticipated debt financing requirements while preserving potential upside exposure to strengthening manganese prices.

The proposed arrangement advances Chvaletice's position as a secure, traceable European source of high-purity manganese for North American battery and advanced-manufacturing supply chains.

Euro Manganese and 6K Energy intend to negotiate a definitive offtake agreement under which the contemplated pricing mechanism, volumes and other commercial terms would become binding.

The term sheet also establishes a framework for the parties to evaluate broader commercial opportunities involving Euro Manganese's products and their use within 6K Energy's operations.

6K Energy's successful testing and preliminary qualification of Euro Manganese's material from its Demonstration Plant represents an important technical endorsement of the Company's product quality and suitability for advanced battery materials applications. It also underscores the potential value of Euro Manganese's secure, traceable and responsibly produced manganese to customers seeking alternatives to existing sources of supply. The term sheet contemplates a long-term, take-or-pay offtake arrangement. Pricing is expected to be based on a market-linked mechanism that reflects prevailing market conditions. The pricing structure contemplated by the term sheet is designed to support the Project's anticipated debt financing requirements, while also providing Euro Manganese the potential to capture, in whole or in part, the benefit of any potential strengthening in manganese pricing as markets evolve over the coming years. The Company regards this as a further demonstration of the pragmatic, efficient approach it has taken to developing Chvaletice, an approach intended to perform across a range of market conditions while preserving upside exposure for shareholders.

The parties intend to explore further opportunities involving Euro Manganese's products within 6K Energy's business. Together with the preliminary qualification of the Company's material, this framework reinforces the commercial relevance of Chvaletice to customers seeking reliable supplies of high-purity manganese from a secure Western source.

Martina Blahova, President and Chief Executive Officer of Euro Manganese, commented:

"This term sheet represents an important step toward converting customer interest into a long-term commercial relationship. 6K Energy's successful testing and preliminary qualification of our material provide valuable validation of its quality and suitability for advanced battery-material applications.

"Chvaletice's planned ability to produce both high-purity manganese metal and high-purity manganese sulphate would provide customers with flexibility across a range of manufacturing processes and strengthen the Project's relevance to Western supply chains. We look forward to advancing negotiations toward a definitive offtake agreement and exploring broader opportunities with 6K Energy, including the potential supply of high-purity manganese intended to meet applicable requirements under the U.S. National Defense Authorization Act."

Aaron Kless, Senior Vice President of Global Operations at 6K Energy, commented:

"Establishing secure, transparent and resilient supply chains for critical battery materials is central to the growth of domestic cathode manufacturing. The successful testing and preliminary qualification of Euro Manganese's high-purity manganese material is an encouraging step in our evaluation process.

"We are pleased to establish this framework with Euro Manganese and look forward to advancing our discussions toward a definitive agreement while exploring opportunities to support 6K Energy's long-term material requirements and the continued development of a competitive North American battery supply chain."
