Rock Tech Obtains LEI Number

Vancouver, BC, Canada – December 18, 2017 – Rock Tech Lithium Inc. (the "Company" or “Rock Tech”) [TSX-V: RCK; Frankfurt: RJIB (WKN: A1XF0V)] announces that it has been granted a Legal Entity Identifier (“LEI”). The Company’s LEI code is 529900SUTRHXAAHH7648.

About the Legal Entity Identifier

The LEI initiative is designed to create a global reference data system that uniquely identifies every legal entity or structure, in any jurisdiction, that is party to a financial transaction. Endorsed by the G20, the establishment of a Global LEI System (“GLEIS”) is critical to improving measurement and monitoring of systemic risk. Global, standardised LEIs will enable regulators and organisations to more effectively measure and manage counterparty exposure while also resolving long standing issues on entity identification across the globe.
