Rock Tech Lithium Completes 2021 - 2022 Drill Program at Georgia Lake

Exploration Programs

Rock Tech Lithium Completes 2021 - 2022 Drill Program at

Georgia Lake

VANCOUVER, BC

,

Oct. 7, 2022

/CNW/ -

Rock Tech Lithium Inc.

(TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V)

(the "Company" or "Rock Tech") is pleased to announce the final results from the

Company's recently completed 2021 – 2022

drill program (the "Drill Program") at its 100%-owned Georgia Lake lithium project in the Thunder Bay Mining District of

Ontario

(the "Georgia Lake Project"

).

Rock Tech is pleased to announce the final results from its completed 2021 – 2022 Drill Program. The Drill Program was designed

to support the Company's ongoing pre-feasibility study in respect of the Georgia Lake Project, which the Company expects to

publish in the fourth quarter of 2022. The final drill results are from exploration drilling completed during the winter and spring of

2022. Commenting on the Drill Program,

Robert MacDonald

, General Manager of the Georgia Lake Project, said, "Rock Tech is

pleased to conclude this phase of our Drill Program, and with that, we are looking forward to the completion of our pre-feasibility

study later this year while continuing to progress permitting work in respect of the Georgia Lake Project."

The objective of the Drill Program was to increase the confidence in the current mineral resource estimate in respect of the

Georgia Lake Project and to upgrade the resource classification from predominantly inferred resources to predominantly indicated

resources, as well as test potential extensions of the mineral resource down dip and along strike of the deposits. Assay results

from the initial 70 holes drilled during the 2021 – 2022 Drill Program were announced by the Company on

January 12, 2022

and

June 30, 2022

, respectively.

In addition to the Drill Program, Rock Tech is also pleased to announce that it executed a successful mapping and prospecting

program commenced in summer 2022 at the Georgia Lake Project in areas both proximal to known spodumene-bearing pegmatite

deposits and in under-explored areas within its 6,728 hectares property. The Georgia Lake Project, located between

Nipigon

and

Beardmore, Ontario

is comprised of 1,042 hectares of mineral leases and 5,686 hectares of mineral claims. Since the start of the

Drill Program in 2021, the Company has completed a total of 23,200 metres of diamond drilling that focused on five spodumene

pegmatite deposits known as the Main Zone North ("MZN"),

Conway

, Main Zone Southwest ("MZSW"), Harricana and Line 60.

KEY EXPLORATION HIGHLIGHTS

Fourty-six (46) NQ

1

diamond drill holes totaling 13,829 metres were completed at the MZN deposit.

Thirty-five (35) NQ diamond drill holes totaling 5,943 metres were completed at

Conway

.

Sixteen (16) NQ diamond drill holes totaling 3,437 metres were completed at MZSW, Harricana and Line 60.

Significant assay results from remaining 27 holes Rock Tech have been waiting for lab results include:

at MZN and

Conway

(see details below), and also identified a new mineralized zone south of the MZN deposit. Significant

assay intersections from the new zone include:

DETAILS ABOUT THE MAIN ZONE NORTH DRILLING

The MZN deposit contains multiple stacked pegmatite dikes that are grouped into the "Northern" and "Southern" pegmatite

systems at MZN. Spodumene mineralization at MZN strikes at 235 degrees for over 1 km and dips 60 degrees to the northwest.

At MZN, the Drill Program extended spodumene mineralization for 50 – 100 metres down dip of known pegmatites for about 300

metres along strike on the eastern side of the deposit (See Table 1 and Figures 1 to 3 in the Appendix to this press release). A

new mineralized zone was also discovered 150 – 300 metres south of the "MZN" deposit where historic drill holes and mapping

showed sporadic spodumene mineralization (See Figure 1 and assay results for drill holes NC-22-17 to -19, NC-22-26, and NC-22-

28 to -31 in Table 1, respectively, in the Appendix to this press release).

DETAILS ABOUT THE

CONWAY

DRILLING

The

Conway

deposit hosts one main pegmatite dike with spodumene mineralization striking at 210 degrees for 800 metres and

dips 70 degrees to the northwest. The 2021 – 2022 drilling at

Conway

extended spodumene mineralization for 100 metres along

strike to the south, to the 75 metres level (See Table 2 and Figures 4 and 5 in the Appendix to this press release).

DETAILS ABOUT DRILLING AT MAIN ZONE SOUTHWEST

The MZSW deposit, located 1 km to southwest of MZN deposit, hosts three parallel – sub-parallel spodumene pegmatites that

strike at 235 degrees for 300 metres, dipping 70 degrees to the northwest. See Table 2 in the Appendix to this press release for

assay results in drill hole MZSW-21-02.

SAMPLING AND QAQC PROCEDURE

Samples were taken across every spodumene-bearing pegmatite and 1 metre into the barren host rock on either side of the

dykes. Sample lengths were around 1 metre, though individual sample length was determined based on internal zoning of the

dykes and the locations of their contacts. Core to be sampled was cut in half with one half being sent for analysis and the other

half remaining in the box for reference. All core is stored at Rock Tech's core facility in

Beardmore, Ontario

. Each sample was put

into its own plastic sample bag with a sample tag and closed with zip ties. About 13% of the samples submitted to Activation

Laboratories Ltd. ("

Actlabs

") for analysis were QAQC samples that were inserted into the sample stream and consist of a high-

and low-grade lithium standards, blank material, and duplicates. Samples were sent to Actlabs' preparation laboratories in

Geraldton

and

Thunder Bay, Ontario

for crushing and pulverizing, and were subsequently sent to Actlabs' geochemistry laboratory

in

Ancaster, Ontario

for analysis of 41 elements using fusion plus ICP-OES or ICP-MS. Analysis for lithium was completed using a

sodium peroxide fusion plus ICP-OES. Actlabs is independent of the Company.

results, performance and/or achievements to vary materially include: the Company's ability to access funding required to invest in

available opportunities and projects (including the Georgia Lake Project) and on satisfactory terms; the current and potential

adverse impacts of the COVID-19 pandemic and ongoing geopolitical hostilities; the risk that Rock Tech will not be able to meet its

financial obligations as they fall due; changes in commodity and other prices; Rock Tech's ability to attract and retain skilled staff

and to secure feedstock from third party suppliers; unanticipated events and other difficulties related to the construction,

development and operation of the Georgia Lake Project and/or the Company's proposed lithium converters; the cost of compliance

with current and future environmental and other laws and regulations; title defects; competition from existing and new competitors;

changes in currency and/or exchange rates and the market prices of Rock Tech's securities; Rock Tech's history of losses;

adverse impacts of climate change; and other risks and uncertainties described from time to time in Rock Tech's public disclosure
