Rock Tech Lithium Inc.

(the "Company" or "Rock Tech")

[TSX-V: RCK;

Frankfurt

: RJIB (WKN: A1XF0V)] is pleased to announce that it has completed a

hydrogeological survey on the Georgia Lake property. The investigations were conducted by DMT

GmbH & Co. KG ("DMT") as part of its work on the first-ever Preliminary Economic Assessment

("PEA") at Rock Tech's flagship, 100%-owned Georgia Lake lithium property in the Thunder Bay

Mining District of

Northwest Ontario

, Canada.

The hydrogeological investigations help estimate the recharge of groundwater and the catchment

areas, information important to define mining costs at the property. The data collected indicate that

the drainage concept to be developed during mine planning should not pose special challenges. In

addition to groundwater level measurements on existing boreholes, water permeability tests in

boreholes using open systems were carried out. The derived transmissivities and hydraulic

conductivities show low permeabilities which should not cause any major disruption to the intended

type of mining drainage. The work supported the results of the hydrogeological work performed on

the property in the late 1950's and during 2010/2011 when Rock Tech commissioned baseline

ecological and water balance studies for the purpose of the permission process for future advanced

exploration on the Georgia Lake lithium property.

"Valuable data and preparations have already been identified for current and subsequent feasibility

studies and environmental impact assessments," said

Martin Stephan

, Rock Tech's CEO. "Thus,

further hydraulic field trials and studies on the groundwater conditions are planned to support and

expand on the hydrogeological findings that have now been developed."

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.
