VANCOUVER, April 20, 2017 /CNW/ - 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 are from channel samples taken from the Aumacho pegmatite, and are the highest grade results to date for this channel sampling program. Three (3) channels were cut and eighteen (18) samples taken.

Rock Tech's CEO, Martin Stephan, commented, "The channel sample assay results from the Aumacho area are exceptional, showing grades up to 4.42% lithium oxide, the highest grades encountered to date. We have completed just three drill holes and four channel samples at Aumacho since acquiring the Georgia Lake property as the majority of our investment was aimed at confirming historic resources in the Nama Creek area and upgrading these to NI 43-101 standards. Further exploration work here is certainly warranted as the Aumacho area represents excellent potential for increased lithium resources."

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 Aumacho area of the property consists of three lithium-bearing pegmatites and was the focus of drill programs conducted by various operators in 1955, 1956, 1957 and 2009. In total, forty-one (41) holes were drilled totalling over 5,460 metres. Based on drill information from 1955-1957, a resource estimate of 236,775 tonnes grading 1.63% Li2O was delineated (The Northern Miner, 1957). The historical estimate does not use the categories set out in sections 1.2 and 1.3 of NI 43-101 and a qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. The Company is not treating the historical estimate as current mineral resources or mineral reserves. Rock Tech drilled three holes totalling 200 metres in 2010 and completed one channel for sampling in 2011. The drill holes were designed to twin historic holes and verify the location of the spodumene pegmatites at depth to get a better understanding of the geology of these pegmatites and their lithium oxide grade and rare earth element potential.

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.
