Lithium Assay Results Returned from Step-out Winter 2023 Drill Program as Rock Tech Initiates Summer Field Exploration at Georgia Lake
Rock Tech completed its step-out winter drill program ("Phase I") as part of its lithium mineralization extension targets for Georgia Lake.
17 exploration holes for a total of 3,676 meters were drilled with supporting assay results for:
Rock Tech has initiated an extensive summer field exploration program ("Phase II") at the Georgia Lake property.
VANCOUVER, BC, July 4, 2023 /CNW/ - Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the "Company" or "Rock Tech") has received positive assay results from its 2023 winter drill program. The completed step-out drilling aims to support the expansion of known pegmatite zones at its 100%-owned Georgia Lake Lithium project in the Thunder Bay Mining District of Ontario (the "Georgia Lake Project").
Rock Tech has successfully completed the drilling of 17 exploration holes for a total of 3,676 meters in the first months of 2023, at the Main Zone North (MZN) and McVittie deposits. It has received assay results for ten holes drilled around MZN and seven holes that were drilled at McVittie (refer to results on Table 1 and Table 2).
Commenting on the Drill Programme, Robert MacDonald, General Manager of the Georgia Lake Project, said, "Rock Tech is pleased to have been able to follow up on our 2021-22 drill results from the MZN and past results from McVittie. Positive results obtained further support the strength of the deposits and extends our understanding of the known pegmatites. We are currently preparing to follow up with a summer field programme and get 'boots on the ground' to support our commitment to our total land package at Georgia Lake."
KEY EXPLORATION HIGHLIGHTS
Ten NQ1 diamond drill holes totaling 2,115 meters were completed at the MZN deposit.
Highlights of assay results from the ten holes at MZN include:
Seven NQ diamond drill holes totaling 1,561 meters were completed at McVittie; assay results include:
Rock Tech intends to increase mineral resources at Georgia Lake Project during 2023 and 2024 through a set of phased exploration programmes. The first phase of this commitment ("Phase I") has been the completion of the winter drill programme at MZN and McVittie.
Rock Tech is also pleased to announce that it has initiated an extensive summer exploration programme ("Phase II") that will focus on prospecting, mapping, and sampling around high priority targets. The work will be followed by trenching and channel sampling on select prospects in both the Northern Spodumene Pegmatite Area (NSPA) and Southern Spodumene Pegmatite Area (SSPA).
This work will follow up on the positive results of the 2022 field programme (see Rock Tech's press release dated January 31, 2023) which sampled pegmatite prospects in close proximity to Rock Tech's NI 43–101 compliant mineral resources (refer to Table 3). Figure 1 and Figure 4 illustrate the locations of the high priority spodumene-bearing prospects at Line 20, Camp 38, Conway East, Caral, Foster Lew, Jean Lake, and Aumacho, where Rock Tech's 2023 summer exploration programme will be focused. The results from Phase II are expected to generate additional drill targets for a Fall 2023 drill programme ("Phase III").
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.
SAMPLING AND QA/QC PROCEDURE
Samples were taken across every spodumene-bearing pegmatite and 1 metre into the barren host rock on either side of pegmatite dikes. Sample lengths are generally around 1 metre, though individual sample length can be determined based on internal zoning of the dikes 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. 16% of the samples that were submitted to Activation Laboratories Ltd. ("Actlabs") for analysis were QAQC samples. QAQC samples were inserted into the sample stream and consist of a high- and low-grade lithium standards, blank material, and duplicates. Samples were dropped at Actlabs' preparation laboratory in Thunder Bay, Ontario for crushing and pulverizing, and subsequently were sent to Actlabs' geochemistry laboratory in Ancaster, Ontario for analysis of 41 elements using fusion plus ICP-OES or ICP-MS. Sodium peroxide fusion plus ICP-OES was used to analyze for lithium. Actlabs is independent of the Company.

ABOUT ROCK TECH
Rock Tech is a cleantech company with operations in Canada and Germany on a mission to produce lithium hydroxide for electric vehicle batteries. The Company plans to build lithium converters at the door-step of its customers, to guarantee supply-chain transparency and just-in-time delivery, beginning with the Company's proposed lithium hydroxide merchant converter and refinery facility in Guben, Germany. To close the most pressing gap in the clean mobility story, Rock Tech has gathered one of the strongest teams in the industry. The Company has adopted strict environmental, social and governance standards and is developing a proprietary refining process aimed at further increasing efficiency and sustainability. Rock Tech plans to source raw material from its wholly-owned Georgia Lake spodumene project located in the Thunder Bay Mining District of Ontario, Canada, as well as procuring it from other responsibly producing mines. In the years to come, the Company expects to also source raw material from discarded batteries. Rock Tech's goal: to create a closed-loop lithium production system. www.rocktechlithium.com
