Channel Sample Assay Results Extend Length and Width of Pegmatites at Georgia Lake

Vancouver, BC, Canada – March 30, 2017 Rock Tech Lithium Inc. (the “Company” or “Rock Tech”) (TSX-V: RCK; Frankfurt: RJIB) is pleased to announce additional channel sample assay results from its recently completed exploration program at its 100%-owned Georgia Lake lithium property in the Thunder Bay Mining District of Northwest Ontario, Canada.

The assay results contained in this news release are from channel samples taken from the West, Harricana, Line 60, Newkirk, MZSW and Conway pegmatites. Seventy-four (74) channels were cut and three hundred twenty-five (325) samples taken from these pegmatites.

Rock Tech’s CEO, Martin Stephan, commented, “These channel sample results, specifically those from the area of the West, Line 60 and Harricana pegmatites, suggest the presence of a multiple dike system exceeding what was previously thought to be just three dikes. Furthermore, channel sampling on Line 60 increased the width of the pegmatite far more than anticipated. On the Conway pegmatite, the results confirmed the extension of the pegmatite to surface and along strike to the south.”

The exploration program targeted nine (9) of the known lithium-bearing pegmatite occurrences and has expanded on the wealth of knowledge obtained through past exploration programs that led to the Company’s National Instrument (“NI”) 43-101 resource estimate.

The purpose of the channels was to gain information on the location of the pegmatites on surface and to aid in drill targeting in the future. Assay result highlights are summarized in the following table:

The channel samples were analyzed by Actlabs, an ISO 9001:2008 certified analytical laboratory located in Geraldton, Ontario.

Rock Tech is the only exploration company in the Georgia Lake region with an NI 43-101 resource estimate. Further, the Company has completed metallurgical testing on a bulk sample demonstrating the ability to produce both a high-grade spodumene concentrate and battery-grade lithium carbonate (“Li2CO3”). The spodumene-bearing pegmatites of the Georgia Lake area were originally discovered in 1955.

All scientific and technical information in this news release concerning the Georgia Lake lithium property was reviewed and prepared under the supervision of Locke B. Goldsmith, P.Eng., P.Geo., an independent Qualified Person to Rock Tech.
