Vancouver, British Columbia, Canada, September 13, 2012 – Rock Tech Lithium Inc. (TSX-Venture: RCK; Frankfurt: RJIA; Pink Sheets: RCKTF) (the “Company” or “Rock Tech”) is pleased to announce the results of surface grab samples taken from its Lochaber graphite property in Quebec, Canada. The results demonstrate the presence of graphite mineralization with grades up to 22% graphite.

In May 2012, a total of eleven (11) surface samples were collected from various outcrops and boulders as part of a due diligence property visit by the Company’s geological team. The majority of the samples were collected from the historical graphite occurrences, past producing mines and other areas of past exploration work. The surface samples were submitted to Techni-Lab Abitibi Inc., a branch of Activation Laboratories Ltd., and were tested by using the following analytical packages: Code 5D, analyzing C-Graphite (infrared) where the sample is subjected to a multistage furnace treatment to remove all forms of carbon with the exception of graphitic carbon; and C-Total (infrared), a procedure that determines the most volatile organic carbon species.

Company President and CEO, Eunho Lee, commented, “We are pleased with the results of the grab samples as they confirm the presence of graphite mineralization on our Lochaber project.”

Analytical results are presented in the following table:
