Rock Tech Lithium Inc. (TSX-V: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) is pleased to announce the latest assay results from the Company’s ongoing drill program at its 100%-owned Georgia Lake lithium project in the Thunder Bay Mining District of Ontario.

Rock Tech began the Drill Program in 2021 in support of an ongoing pre-feasibility study being conducted in respect of the Georgia Lake Project.. The current drilling results are from test drilling completed during the fall 2021 and winter 2022 portions of the Drill Program and will be included in the Georgia Lake Project pre-feasibility study. These results comprise the second of 3 batches of results from the winter 2021 and spring 2022 phase of the Drilling Program. Commenting on the Drill Program, Robert MacDonald, General Manager of the Georgia Lake Project, said, “Rock Tech is pleased with the progress of our Drill Program at our Georgia Lake Project. We are continuing to focus on completing a pre-feasibility study in respect of the Georgia Lake Project while concurrently pursuing project permitting.”

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 (see Figure 1).  Since the start of the Drill Program in 2021, the Company has completed approximately 21,000 metres of diamond drilling that focused on five spodumene pegmatite deposits known as the Main Zone North, Conway, Main Zone Southwest, Harricana and Line 60 (see Figure 2).

The objective of the Drill Program is 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. The assay results from the initial batch of core samples from the Drill Program were announced in a press release dated January 12, 2022.

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 Figure 3 to Figure 5)

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 Figure 5 and Figure 6).

DETAILS ABOUT MAIN ZONE SOUTHWEST, HARRICANA, AND LINE 60

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. The Harricana and Line 60 deposits are located 1 and 1.5 kms to the southeast of MZN deposit. Harricana contains two sub-parallel dikes, Harricana Main and Harricana West. Harricana Main strikes at 220 and dips 60 degrees to the northwest. Harricana West strikes at 220 and dips 60 degree to the northwest in the southern half of the dike; however, the orientation of the dike changes to strike of 140, dipping 60 degrees to the southwest, in the north. See Table 3 and Figure 5 for significant pegmatite intersections at MZSW and Harricana.

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. 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.

ABOUT ROCK TECH LITHIUM INC. 

Rock Tech Lithium Inc. is a cleantech company with operations in Canada and Germany that aims to supply the automotive industry with high quality, “made in Germany” lithium hydroxide. As early as 2024, Rock Tech intends to commission Europe’s first lithium converter with a production capacity of 24,000 tonnes per year. This is equivalent to the volume needed to equip around 500,000 electric cars with lithium-ion batteries.

Rock Tech owns the Georgia Lake Project in Ontario, Canada. The Company has set itself the goal of creating a closed loop for lithium, thus closing the raw material gap on the road to clean mobility. As early as 2030, around 50 percent of the raw materials used by Rock Tech are expected to come from the recycling of batteries.
