PRESS RELEASE

Strategic partnership: Mercedes-Benz intends to source

battery material lithium hydroxide from Rock Tech Lithium

Vancouver, August 23, 2022 – Rock Tech Lithium Inc (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN:

A1XF0V) ("Rock Tech") and Mercedes-Benz AG ("Mercedes-Benz") are pleased to announce that they are

about to enter into an agreement which provides for a strategic partnership to produce high-quality

lithium hydroxide for the automaker and its battery suppliers. Under the intended binding agreement,

Rock Tech has agreed to deliver up to 10,000 tonnes per year of its planned production to the premium

manufacturer and its partners starting in 2026. The two companies made the announcement on

Tuesday during a visit to Canada by a business delegation from Germany led by Chancellor Olaf Scholz.

Mercedes-Benz wants to become fully electric by the end of the decade. From 2025 onwards the luxury

carmaker plans that all newly launched vehicle architectures will be all electric. To help make this a

reality, Mercedes-Benz intends to enter a strategic partnership with Rock Tech, l asting for at least five

years and an option to prolong.

From 2026 onwards, it is envisaged that Rock Tech contributes up to 10,000 tonnes of lithium hydroxide

annually to Mercedes-Benz and its battery partners, starting with a qualification period and after quality

and sustainability benchmarks have been met. This battery-grade lithium product is an essential

component of high- performance vehicle batteries. The Canadian -German Rock Tech expects to

become a central implementation partner for the automaker and its all electric and carbo n neutral

strategies.

With the envisaged strategic partnership, both companies aim to ensure that the amount of battery-

grade lithium meets Mercedes-Benz’s growing demand in order to scale up electric vehicle production .

Rock Tech is currently developing its first converter project in Guben, eastern Germany. So far, no other

refinery of its kind exists in Europe. Rock Tech aims to close this gap in supply of lithium and to make

regional supply chains more resilient by refining spodumene into high quality l ithium hydroxide at this

converter by the end of 2024. This would create a short supply chain in Mercedes -Benz’s origin and is

expected to further strengthen the partnership.

“With the envisaged agreement, we intend to provide Mercedes-Benz not only with high-quality lithium

hydroxide, but also to establish a strategic partnership that is expected to set new standards in

sustainable supply chains. We are very pleased to have found a partner that intends to take important

steps with us towards a more resilient and sustainable lithium supply chain to deliver an important part

of their strategy and of the e-mobility transformation", says Markus Bruegmann, Chief Executive Officer

of Rock Tech Lithium.

“Mercedes-Benz plans to go all electric by the end of this decade, wherever market conditions allow. To

scale up our electric vehicle production, access to raw materials is needed to improve the resilience and

sustainability of the electric vehicle supply chain. With the Rock Tech part nership we intend to take a

direct sourcing approach to secure the lithium supply for Mercedes -Benz battery production”, says

Markus Schaefer, Member of the Board of Management of Mercedes-Benz Group AG, Chief Technology

Officer, responsible for Research & Development and Procurement.

Additionally, Rock Tech also intends to operate its own mine in Georgia Lake, Canada, to contribute to

wider and growing lithium demand in the northern hemisphere. With the emergence of new sources of

raw materials within the G7 community, Canada in particular is becoming increasingly important for

resilient supply chains. Rock Tech exemplifies how cooperation between Canada and Germany can be

realized. This is one of the reasons why Mercedes -Benz and Rock Tech announced the envisaged

partnership during a business delegation's trip to Canada on Tuesday in Toronto , with reference to

Memorandum of Understanding entered into by Mercedes -Benz and the Government of Canada to

strengthen cooperation across the electric vehicle value chain.

A shared understanding and focus on reliability, resilience, and sustainability in the supply chains in

Europe and North America creates a strong basis for the planned strategic partnership between Rock

Tech and Mercedes -Benz. Rock Tech's sourcing options and its own mining project in Canada are

expected to meet or exceed the standards of the Initiative for Responsible Mining Assurances (IRMA),

whose criteria includes both human rights as pects and the environmentally sustainable mining of raw

materials, among others. In addition, Rock Tech is investigating new methods and technologies aimed at

the carbon neutral industrial production of lithium hydroxide and new zero waste production methods.
