Rock Tech Provides Update on Converter Activities

Vancouver, BC, Canada – February 11, 2021 – Rock Tech Lithium Inc. (the "Company" or

“Rock Tech”) (TSX-V: RCK; Frankfurt: RJIB) wishes to provide an update on its downstream

activities.

The Company is pleased to announce it has engaged Wave International (“Wave”) to complete

basic engineering work and cost estimation for its planned Lithium Hydroxide operations to a

Class 4 level, according to the Association for the Advancement of Cost Engineering (“AACE”).

Wave are an asset development consultant, with extensive experience in the Lithium ion battery

supply chain, and specialist expertise in downstream lithium hydroxide production. Wave have

worked extensively on various world class downstream lithium projects in Australia, Asia and

Europe.

Wave will assist Rock Tech in providing process design, defining the optimal plant

configuration, finalizing site selection, including infrastructure needs, and will also support Rock

Tech in managing the upcoming pilot programs. The pilot programs will assess both the

traditional sulphate route and the Company’s innovative patent-pending Nitrate Process. Rock

Tech aims to produce lithium hydroxide from these programs during the second quarter. In

addition, Rock Tech is in the last due diligence phase on possible converter sites now including

discussions with major stakeholders, locals and permitting agencies in Europe.

Rock Tech is in the process of incorporating a German subsidiary, has recently opened its first

office in Munich and is scaling up its team in both Germany and Thunder Bay, including the

mobilization of the integrated Wave and Rock Tech team into Germany during January this year.

The Company is adding management, engineering, chemistry and marketing specialists to its

team.

Furthermore, the Company has been made aware of a publication based partially on a technical

report previously filed on November 9, 2020. As previously announced on December 18, 2020,

the economic analyses disclosed in a news release dated November 4, 2020, and contained in this

publication, are not currently supported by an NI 43-101 technical report. While this information

remains in the public domain, the Company cannot monitor how the information is being used

now or in the future. The Company reminds not to rely upon it until such time as the revised

report has been filed.
