Rock Tech Lithium and ENERTRAG SE Enter Strategic Partnership for
Sustainable Energy Supply of the Lithium Hydroxide Converter in Guben
At least 50 percent of the electricity demand of Rock Tech's converter in Guben will be supplied directly from new wind and photovoltaic plants operated by
ENERTRAG starting in 2030.
By using renewable energy, indirect CO2 emissions (Scope 2) of the converter can be reduced by approximately 50 percent.
The energy and sustainability concept for the converter in Guben will serve as a blueprint for the converter in
Red Rock, Ontario, Canada

/CNW/ - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock
Tech") Rock Tech and ENERTRAG, in the presence of the Canadian Prime Minister
Mark Carney
as well as
Tim Hodgson
, Canadian Minister of Energy and
Natural Resources, Mélanie
Joly
, Canadian Minister of Innovation, Science and Industry, and
Katharina Reiche
,
Germany's
Federal Minister for Economic Affairs
and Energy, have signed a Memorandum of Understanding (MoU) for the long-term supply of renewable energy for the planned lithium hydroxide converter in
Guben. The goal of the partnership is to ensure a sustainable and competitive electricity supply, providing Rock Tech with planning security for the converter's
operating costs (OpEx). The converter project is recognized as a strategic initiative under the
European Commission's Critical Raw Materials Act
and serves as a
model for the decarbonization of European industry through cross-border cooperation. The concept also serves as a template for building a resilient supply chain
for critical minerals in
Canada
.

A core element of the renewable energy initiative is the direct supply of electricity from new wind and photovoltaic plants in the neighboring Polish municipality of
Gubin. ENERTRAG intends to provide at least 70 GWh of renewable electricity per year under a future power purchase agreement (PPA), covering at least 50
percent of the converter's expected electricity demand. For Rock Tech, this means a significant reduction in indirect CO
2
emissions (Scope 2 GHG) by at least 25
percent.
"With the planned direct supply of our converter with renewable energy, we are setting an important milestone for the sustainable and competitive production of
lithium hydroxide in
Europe
. The partnership with ENERTRAG is an important example of how industry and energy producers can work together in a practical way
to decarbonize the value chain. This not only creates planning security for our project but also contributes to achieving European climate targets," says
Mirco
Wojnarowicz
, Chief Executive Officer (CEO) of Rock Tech Lithium.
From the start of commissioning, a significant share of the converter's electricity demand is to be covered by renewable sources. From 2030 onwards, at least 50
percent of the total electricity demand will be met by renewables.
The project stands as a model for the decarbonization of European industry and underscores the importance of cross-border and cross-company collaboration for
greater sustainability.
Dr.
Gunar Hering
, Chief Executive Officer (CEO) of ENERTRAG adds: "With this partnership, we are demonstrating how tomorrow's industry can be supplied with
climate-friendly and competitive renewable energy today. We are focusing on innovative solutions such as direct electricity supply from new wind and solar parks
in Gubin and the use of process heat through sector coupling. The project with Rock Tech is a milestone for the cross-border energy transition and highlights the
role of the Lausitz-area in Brandenburg as the future region for sustainable industry. Together, we are creating planning security, strengthening the regional value
proposition, and making a true contribution to the decarbonization of the European economy."
The cooperation is subject to positive investment decisions by both parties.
The agreement was signed during the German-Canadian Critical Minerals Round Table. "The partnership between Rock Tech Lithium and ENERTRAG represents
a powerful example of how Canadian innovation and international collaboration can drive the clean energy transition. The Guben converter project, and its future
counterpart in
Red Rock, Ontario
, reflect
Canada's
commitment to building resilient, low-carbon supply chains for critical minerals, while strengthening our
strategic partnership with
Germany
in support of shared climate and economic goals," noted the Honourable Tim Hodgson, Minister of Energy and Natural
Resources. The participation of the Natural Resources Canada (NRCan) underscores the close bilateral cooperation between
Canada
and
Germany
in the field of
critical minerals and clean energy, and highlights Rock Tech's role as a Canadian company contributing to the development of a sustainable transatlantic supply
chain. As a recipient of NRCan funding from the Critical Minerals Infrastructure Fund (CMIF), Rock Tech is proud to continue working with NRCan and the
Government of
Canada
government to advance
Canada's
Critical Minerals Strategy and to further strengthen the Canadian-German transatlantic partnership in
the field of clean energy.
About Rock Tech Lithium

Europe
and
North America
more independent and competitive. The Company's goal is to
ensure the supply of high-quality, locally produced lithium – supporting a resilient, sustainable, and transparent value chain from mine to battery-grade material.
Rock Tech relies on responsible sourcing, state-of-the-art and proven technologies, and a clear focus on circular economy principles. The Company's lithium
hydroxide converter projects in Guben,
Germany
(24,000 tonnes LHM per year) and
Ontario, Canada
(up to 36,000 tonnes LCE per year) form the foundation for
a stable and regional supply to the battery and automotive industries. The Guben converter has been recognized as a strategic project under the EU Critical Raw
Materials Act.
The raw materials for Rock Tech's converter projects are sourced exclusively from verifiably ESG-compliant suppliers. In
Canada
, Rock Tech relies, among other
sources, on its wholly owned Georgia Lake Project, which ensures a stable and sustainable supply for the North American market and is being developed in close
partnership with local First Nations communities. By integrating recycled materials, the company aims to close the local battery loop.
With its facilities, Rock Tech makes a central contribution to battery-grade material sovereignty and the achievement of climate targets. The company works in
partnership with industry, policymakers, and community groups, and is committed to open communication and the highest environmental standards.
