The results of the PEA include a pre-tax Net Present Value ("NPV") of

$312 million

at a discount rate

of 8% and a pre-tax Internal Rate of Return ("IRR") of 62.2%. The PEA focused on only a portion of

the Georgia Lake project centered around an area referred to as the Nama Creek Main Zone,

excluding additional inferred resources the Company has defined on other areas of the property as

included in the updated resource estimate disclosed on

June 27, 2018

and filed on SEDAR on

August 10, 2018

. In the PEA, DMT covered all relevant topics for the development of the mine and

the production of spodumene concentrate, including project infrastructure, mine design and

operations, recovery, processing and reclamation.

"The completion of the PEA is a key milestone in the development of our Georgia Lake lithium

property," said

Martin Stephan

, Chief Executive Officer of Rock Tech. "We are pleased that the

results confirm our optimism with respect to the project and confirm for our shareholders that their

investments in advancing this project have been a success. Although the PEA focused only on a

portion of our NI 43-101 resource estimate, it shows the real value of our company's assets and

proves the excellent profit potential with an expected annual EBITDA of

$64 million

(CAD) which is

nearly double the current market capitalization."

oxide ("Li2O") price of

US$800

per tonne for the first five years and

US$850

About Rock Tech Lithium:

Rock Tech Lithium is an exploration company focused on acquiring and exploring properties in the

field of lithium. The Georgia Lake Lithium project develops 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.
