Rock Tech Announces Third Batch of Assay Results from Trenching Program – Preparation for Upcoming Drill Program

Vancouver, BC, Canada – February 5, 2018 Rock Tech Lithium Inc. (the “Company” or “Rock Tech”) [TSX-V: RCK; Frankfurt: RJIB (WKN: A1XF0V)] is pleased to announce assay results from grab samples collected during the recent trenching and channel sampling program at its 100%-owned Georgia Lake lithium property in the Thunder Bay Mining District of Northwest Ontario, Canada.

This program targeted areas located adjacent to the main resource zone of the Georgia Lake property, an area that hosts an NI 43-101 indicated resource of 2.47 million tonnes grading 1.11% lithium oxide (“Li2O”) and an inferred resource of 2.50 million tonnes grading 0.98% Li2O. In its entirety, the Georgia Lake lithium property hosts an indicated resource of 3.19 million tonnes grading 1.10% Li2O and an inferred resource of 6.31 million tonnes grading 1.00% Li2O.

In January, the Company released assay results from seventeen trenches completed on and in the area around mapped pegmatites located adjacent to the Nama Creek main resource zone. Trenching uncovered at least four pegmatite dykes in the region. An additional lithium bearing pegmatite dyke, in an oblique (NW-SE trending) orientation, was observed in this area and sampled in channels.

Five (5) samples were collected in areas with thick overburden in an effort to trace the pegmatite dykes along strike and identify additional target areas for follow up. The following table contains the grab sample assay results:

Sample Type Grade (% Li2O)
Grab 0.31
Grab 0.76
Grab 1.31
Grab 1.42
Grab 2.28


Martin Stephan, Chief Executive Officer of Rock Tech, commented, “Current exploration work aims to increase resource tonnage significantly both by bringing unverified resources into compliance with NI 43-101 and through new discoveries. Recent trenching and channel sampling results will guide drilling efforts over the next few months.”

The map below shows the locations of the grab samples and their proximity to the main resource zone:

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

The field program was carried out by Pleson Geoscience, an exploration consulting company dedicated to providing its clients with experienced personnel and efficient services. The company’s focus is on low-impact, high resolution data collection from grass-roots prospecting to preliminary economic evaluations.

About Rock Tech Lithium:

Rock Tech Lithium is an exploration company focused on acquiring and exploring properties in the field of lithium and other selected battery metals.

Rock Tech is the only exploration company in the Georgia Lake region of Ontario with an NI 43-101 resource estimate. The resource estimate shows an indicated resource estimate of 3.19 million tonnes grading 1.10% lithium oxide in addition to an inferred resource estimate of 6.31 million tonnes grading 1.00% lithium oxide. 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.
