ABOUT ROCK TECH

Rock Tech's vision is to supply the electric vehicle and battery industry with sustainable, locally produced lithium, targeting

a 100% recycling rate. To ensure resilient supply chains, the company plans to build lithium converters at the doorstep of

its customers, beginning with the Company's proposed Lithium Hydroxide Converter in Guben, Brandenburg,

Germany

.

The second Converter is planned to be built in

Red Rock, Ontario, Canada

. Rock Tech Lithium plans to source raw

material from its own

Georgia Lake

spodumene project in the Thunder Bay Mining District of

Ontario, Canada

, and procure

from other ESG-compliant mines. Ultimately, Rock Tech's goal is to create a closed-loop lithium production system. Rock

Tech has gathered one of the strongest teams in the industry to close the most pressing gap in the clean mobility story.

The Company has adopted strict environmental, social and governance standards and is developing a proprietary refining

process to increase efficiency and sustainability further.
