Rock Tech Announces First Batch of Assay Results from Field Program

VANCOUVER, Sept. 28, 2017 /CNW/ - Rock Tech Lithium Inc. (the "Company" or "Rock Tech") (TSX-

V: RCK; Frankfurt: RJIB) is pleased to announce the first batch of assay results from the field sampling

program recently completed at its 100%-owned Georgi a Lake lithium property in the Thunder Bay Mining

District of Northwest Ontario, Canada.

Phase I of the field program targeted the Parole Lake region, an area of the Georgia Lake lithium prop erty

that hosts at least six lithium-bearing pegmatites. The No. 4 pegmatite was the site of drilling conducted

this past spring and hosts an historic resource estimate. During this field program, the No. 1, No. 2, No. 3

and No. 5 pegmatite dykes were located and georefer enced. While no outcrop was found related to the

No. 6 pegmatite, historic trenches were located and georeferenced. A total of six (6) grab samples wer e

collected from the No. 1 and No. 3 pegmatite dykes, the results of which are presented in the followin g

table:

Area Lithium Oxide (Li2O) %

Parole Lake No. 1 Below detection

Parole Lake No. 1 1.68

Parole Lake No. 1 0.41

Parole Lake No. 1 1.01

Parole Lake No. 1 2.32

Parole Lake No. 3 1.13

Martin Stephan, Chief Executive Officer of Rock Tec h, commented, "The Parole Lake region is one of the

key growth areas of the Georgia Lake lithium proper ty and the sample results confirm that follow up

trenching and drilling is warranted. The geo-referencing of these pegmatites has provided us with mode rn

coordinates and proper locations, increasing the effectiveness of follow up trenching and drilling.

Sampling these pegmatites will provide valuable insights regarding the lithium content of these

pegmatites as assays were not reported for all historic drill holes completed in the 1950's and 1960's ."

Parole Lake Region

The Parole Lake region of the Georgia Lake lithium property hosts at least six lithium-bearing pegmatites.

One of them, the Parole Lake No. 4, was the site of recent drilling and channeling and has an historic

resource estimate of 1.5 million tonnes grading 1.30% Li2O (Pye, 1965); however, the historical estima te

does not use the categories set out in sections 1.2 and 1.3 of NI 43-101 and a Qualified Person has no t

done sufficient work to classify the historical estimate as current mineral resources or mineral reserves.

As a result, the Parole Lake pegmatite is not included in Rock Tech's NI 43-101 resource estimate.

The results from the recent channel program confirm ed the presence of high-grade lithium mineralization

on surface with a sample showing an average grade o f 1.89% Li2O over 4.22 metres, including 2.69%

Li2O over 1.03 metres. The recently completed drill program, with one intersection averaging 1.53% Li2O

over 11.65 metres, confirmed lithium mineralization at depth, provided a better understanding of the

geometry of the lithium-bearing pegmatite, and will greatly enhance the efficacy of future drill programs.

Additional drilling is required before estimation of true width in core intersections can be determine d. For

complete details of the channel sample and drill results, please see the news releases dated May 3 and

June 29, 2017, respectively.

All samples were analyzed by Actlabs, an ISO 9001:2 008 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.

All scientific and technical information in this news release concerning the Georgia Lake lithium prop erty

was reviewed and prepared under the supervision of Locke B. Goldsmith, P.Eng., P.Geo., an

independent Qualified Person to Rock Tech.

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 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.
