Rock Tech Receives Positive Results from Unconfined Compressive Strength

Tests

VANCOUVER, Aug. 20, 2018 /CNW/ - Rock Tech Lithium Inc. the "Company" or "Rock Tech") [TSX-V:

RCK; Frankfurt: RJIB (WKN: A1XF0V)] is pleased to announce that it has received the lab results for

Unconfined Compressive Strength ("UCS") testwork. The UCS tests were carried out in DMT GmbH &

Co. KG's ("DMT") geotechnical laboratory 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 UCS tests provide specific geotechnical parameters for the design of mine layout. As a result,

following the standards set by the International Society for Rock Mechanics, the main rock types from

Rock Tech's Georgia Lake lithium property can be classified as "strong" to "very strong" rocks with

strength parameters of up to 245 megapascal (MPa).

"The positive results from the UCS tests and the encouraging hydrogeological results recently

announced, represent important milestones along the path to complete the preliminary economic

assessment at our Georgia Lake lithium project," commented Martin Stephan, Rock Tech's CEO. "The

positive results from the UCS tests will now be implemented in the preliminary design of the mine

contemplated in the PEA."

Twelve (12) cylindrical samples from Rock Tech's drill core, together with two (2) rock samples of

pegmatite from the field, representing the main rock types encountered in the planned mining area, were

submitted to the lab for testing.

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.

All scientific and technical information in this news release was reviewed and prepared under the

supervision of Karl-Stephan Peters, EurGeol 787, an independent Qualified Person to Rock Tech.

Additionally, the Company announces the extension of its technical services agreement with Arriva

Management through December 31, 2018. As partial compensation for the services to be provided, Arriva

will receive $39,000 worth of common shares of the Company, paid in tranches after services have been

rendered. The agreement and the issuance of the common shares are subject to the approval of the TSX

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.
