Sixth Wave Innovations Inc. reported on extraction and recovery of lithium from spodumene found at the Champlain Mineral Ventures Ltd. ("CMVL") Brazil Lake property. The focus of the work has been to develop a greener process for conversion of spodumene from alpha to leachable beta spodumene and simplify the process flow sheet to achieve battery grade lithium carbonate. Key objectives are to lower energy costs and utilize safer and greener reagents.

Fewer process steps reduce the environmental impact of processing lithium bearing spodumene. The Company completed initial baseline testing of conventional processing using calcination for spodumene conversion and comparison of a conventional sulfuric acid leaching and an improved version of flow sheet utilizing a sodium carbonate solution for leaching. Conventional processing showed adequate recovery to baseline results for a competitive comparison of advanced pathways being developed by Sixth Wave.

In summary, the Company has moved significantly forward in elimination and minimized use of toxic reagents and simplifying the process flow sheet while providing a competitive and commercially viable process to battery grade lithium carbonate production. Next steps in the work include continued simplification of the flow sheet to take advantage of lower energy technologies, such as microwave, to convert the spodumene and combining the conversion and leaching steps to further reduce OPEX and CAPEX. In addition, the Company is exploring other unique non-toxic and biodegradable lixiviants targeted toward lithium.

While there is some early work to draw on the Company believes that it is developing protectable new intellectual property both in processes as well as fundamental extraction and purification technology. Sixth Wave and CMVL are committed to sustainable mining and high Environmental, Social, and Governance (ESG) standards. The Company acquired all rights to an emerging class of "green lixiviants" that have direct application to hard-rock lithium mining Green lixiviants garner attention due to their unique properties that are inherently non-toxic, biodegradable with negligible or no vapor.

Sixth Wave expects this lixiviant to eliminate costly high energy processes including roasting to convert the spodumene to a leachable state. Subsequent purification of the leached lithium will be assessed using Sixth Wave's IXOS® molecular technology to produce high purity lithium carbonate.
