Rock Tech and Imagine Lithium to Collaborate on Developing Northern Ontario Supply Chain

• Rock Tech and Imagine to collaborate on exploring potential mergers and acquisitions, commercial partnerships, and joint exploration and development of their lithium projects.
• The companies want to establish a reliable raw material supply chain to support Rock Tech's proposed lithium converter along Lake Superior's North Shore.
• Imagine's Jackpot Project is only 15 kilometers away from Rock Tech's proposed Georgia Lake concentrator, and the adjacent properties total approximately 25,000 hectares in the Northern Spodumene Pegmatite area.

THUNDER BAY, Nov. 14, 2023 - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock Tech") is strengthening its Northern Ontario strategy by entering into a memorandum of understanding with Imagine Lithium Inc. (TSXV: ILI) ("Imagine") to explore cooperation opportunities, including but not limited to commercial partnership structures, M&A schemes, joint exploration and development of their projects. The two companies will explore proximal synergies between the adjacent and nearby properties with the joint target to develop a reliable raw material supply chain to support Rock Tech's proposed lithium converter along Lake Superior's North Shore.

Rock Tech's Georgia Lake property, spanning approximately 5,700 hectares, and Imagine's Jackpot Project, which encompasses nearly 19,000 hectares, share contiguous boundaries between both companies' respective projects, which are internally connected by the Gorge Creek Road. Further, the Jackpot Project is strategically situated within 15 kilometres of the planned Georgia Lake concentrator in the Northern Spodumene Pegmatite area. Both companies have been actively engaged in exploration drilling, resulting in the identification of significant spodumene-bearing pegmatites and expanding on known resources.

"The growth potential is enormous if we collaborate with our neighbours in this area. We have already demonstrated that we can derive real economic value from mineral resources in our Northern Spodumene Pegmatite area. Developing accretive synergies in the Southern Spodumene Pegmatite area with our neighbour provides a genuine opportunity to transform the region into a leading lithium hub," said Robert MacDonald, General Manager of Rock Tech.

Imagine Lithium's J.C. St-Amour, President, also appreciates the joint development opportunities, ""Given the proximity of our projects to each other, collaboration with Rock Tech would only strengthen the potential economics of a standalone development in the Nipigon area, strategically proximal to the downstream opportunities. Imagine continues to have ongoing drilling success in the main Jackpot zone, as well as defining multiple new and exciting spodumene bearing pegmatites across our extensive landholding. Following the upcoming winter drill program, we expect to release a 43-101 resource estimate for the property in Q2 of 2024. In addition, Imagine remains well funded, following a $9.1 M placement in April."

The collaboration between the two companies will unlock and deliver significant value for shareholders, including joint exploration, processing ore in a centrally located concentrator, and shared infrastructure development. In the coming weeks, both companies will assess the mutual interests. Rock Tech will also reassess its target date for starting operations at Georgia Lake to align with the execution of its converter strategy.

Rock Tech is a cleantech company with operations in Canada and Germany on a mission to produce lithium hydroxide for electric vehicle batteries. The Company plans to build lithium converters at the doorstep of its customers, to guarantee supply-chain transparency and just-in-time delivery, beginning with the Company's proposed lithium hydroxide merchant converter and refinery facility in Guben, Germany. To close the most pressing gap in the clean mobility story, Rock Tech has gathered one of the strongest teams in the industry. The Company has adopted strict environmental, social and governance standards and is developing a proprietary refining process aimed at further increasing efficiency and sustainability. Rock Tech plans to source raw material from its wholly-owned Georgia Lake spodumene project located in the Thunder Bay Mining District of Ontario, Canada, as well as procuring it from other responsibly producing mines. In the years to come, the Company expects to also source raw material from discarded batteries. Rock Tech's goal: to create a closed-loop lithium production system. www.rocktechlithium.com

Imagine is a junior mining exploration company focused on seeking and acquiring world-class mineral projects. The company holds the Jackpot lithium property located in the Georgia Lake area about 140 km NNE of Thunder Bay, Ontario, is approximately 12 km by road from the TransCanada Highway (Hwy 11), and is in proximity to sources of power, railroads, and ports. The property contains known lithium-bearing granitic pegmatite dikes, of which two provided estimated historical resources of 2 million tons at 1.09% Li2O and 750,000 tons at 1.38% Li2O.
