/CNW/ - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FSE: RJIB) has entered a technology

partnership with GEA Group AG, one of the world's largest system suppliers for advanced process technology, to deliver key equipment for

its Lithium Converter in Guben,

Germany

. As part of the agreement, GEA will supply crystallization and zero-liquid discharge technology,

ensuring the highest standards in battery-grade lithium hydroxide monohydrate (LHM) production.

Following two and a half years of an intensive selection process followed by technical specifications and negotiations, Rock Tech has

successfully completed test works with GEA to procure crystallizers essential to produce 24,000 tons of battery-grade LHM annually. This

equipment contract is a significant step to establish an automated and continuously operating Lithium Converter in

Europe

.

"Finalizing the commercial and technical contract conditions is a key milestone, ensuring clarity, minimizing risks, and enabling efficient

execution. We are pleased to have reached this milestone with such a reputable partner as GEA, establishing a strong foundation for

successful collaboration," says Frank Spellier, Rock Tech's Head of Engineering.

The cooperation with GEA ensures that Rock Tech benefits from the company's extensive process knowledge, market expertise, and

technical capabilities. In the past few years GEA has contributed to key lithium crystallization projects globally. Among others, GEA supplied

technology for a lithium hydroxide plant in

Argentina

(25,000 tons/year), two process plants for lithium hydroxide production in

South Korea

, a

facility producing 20,000 tons/year in

Europe

and crystallization and drying technology for an Australian Lithium plant. Additionally, GEA

supplied several lithium hydroxide production lines focusing on solid-liquid separation technologies for a leading North American Lithium

producer. These projects underscore GEA's expertise in high-purity lithium hydroxide production for battery applications. With terms on

scope, services, warranties, and timelines now finalized, the formal contract signing is the next step, subject to the project's Final Investment

Decision (FID).

As Rock Tech progresses toward the finalization of the contract, preparations are in place to integrate GEA's high-automation solutions,

allowing continuous lithium production at the Guben site.
