Rock Tech Receives Positive Results from

Geotechnical Rock Mass Classification

VANCOUVER

,

Sept. 17, 2018

/CNW/ -

Rock Tech Lithium Inc.

(the "Company" or "Rock Tech")

[TSX-V: RCK;

Frankfurt

: RJIB (WKN: A1XF0V)] is pleased to announce geotechnical rock mass

rating results. The geotechnical investigations were carried out by DMT GmbH & Co. KG's ("DMT")

during a recent field visit and subsequent analyses were conducted in

Essen, Germany

, as part of

its work on the first-ever Preliminary Economic Assessment ("PEA") at Rock Tech's flagship Georgia

Lake lithium property.

The geotechnical investigations and analyses, conducted in accordance with the Q-system for rock

mass classification, were based on geotechnical logging of more than 1,000 metres of core from the

Georgia Lake lithium property. The core analyzed was selected from different locations representing

the main rock types that host the main lithium-bearing pegmatites. DMT qualitatively evaluated the

characteristics of the joints in the rock mass, including information from the compressive strength

tests and hydrogeological work previously announced. The Q-system results for the meta-sediments

and gneiss show that the overall rock mass can be classified as "good rock."

"Rock strength and the existing disintegration of the rock mass are essential factors when

considering the stability of an excavation," said

Martin Stephan

, Rock Tech's Chief Executive Officer.

"It is encouraging that the laboratory tests on the rock strength at our Georgia Lake lithium property

have shown that the intact rock is "strong" to "very strong.""

The ongoing preliminary economic assessment is based on the updated and upgraded resource

estimate announced on

June 27, 2018

. The updated and upgraded resource estimate included the

following:

Measured: 1.89 million tonnes grading 1.04% lithium oxide ("Li2O");

Indicated: 4.68 million tonnes grading 1.00% Li2O;

Inferred: 6.72 million tonnes grading 1.16% Li2O.

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. The Georgia Lake Lithium project aims to develop

a lithium-rich pegmatite vein deposit for the purpose of mining. The deposit was discovered in the

Thunder Bay Mining district in northwestern

Ontario/Canada

, close to the

Lake Superior

, as early as

1955. Rock Tech Lithium has been working increasingly on the property since 2016 – in a market

environment, where the trend for electric cars on the international market has been rising steeply for

years. Analysts expect that more than 25% of newly sold cars in 2025 will be electrified, with the

demand for batteries and therefore battery metals such as lithium expanding rapidly.
