VANCOUVER, BC, March 7, 2023 /PRNewswire/ – Rock Tech Lithium Inc. (TSXV: RCK) (OTCQX: RCKTF) (FWB: RJIB) (WKN: A1XF0V) (the “Company” or “Rock Tech”) is pleased to announce that the company has mobilized a diamond drill rig to start the first phase of the 2023 exploration drill campaign at its 100%-owned Georgia Lake Lithium project in the Thunder Bay Mining District of Ontario (the “Georgia Lake Project”).

“It is our aim for 2023 to unlock the exploration potential of our Georgia Lake Project by advancing our drilling and prospecting activities across the land package. We are pleased to be able to initiate a drill program which we believe will grow our MZN and McVittie deposits as the first phase of our 2023 exploration campaign. I expect that our exploration program will lead to a sizeable increase of our Resource over the next year,” Dirk Harbecke, Rock Tech’s Chief Executive says.

Rock Tech intends to increase its total mineral resources at its 100% owned Georgia Lake project during 2023 and 2024. The first phase of this commitment (“Phase I”) is the mobilization of a diamond drill rig for the completion of a 3,500 meters program. The exploration drilling will include targeted drilling, aimed at expanding the existing Spodumene mineralization at Main Zone North (MZN) and McVittie deposits. (Refer to Figure 1 below for location of MZN and McVittie.)

The MZN deposit currently contains the largest Mineral Resource within the Georgia Lake Pegmatite Field and remains open along strike to the east. The planned drilling will aim at extending Spodumene mineralization along strike to the east of MZN. Additional step-out drilling south of MZN will focus on extending mineralization in areas where Rock Tech have identified new mineralization during the 2022 drilling program (published on October 7th, 2022, and titled „Rock Tech Lithium Completes 2021 – 2022 Drill Program at Georgia Lake”).

The McVittie deposit comprises three spodumene dikes which have been mapped for more than 600m of strike length. It currently has an Inferred Resource of 1Mt at 1.0% Li2O and is open at depth and along strike in both directions.

On November 15, 2022, the Company reported a Mineral Resource estimate of the Georgia Lake Property in its Prefeasibility Study (“PFS”). It outlined 10.60 million tonnes (mt) of Indicated Mineral Resource at a grade of 0.88% Li2O and 4.22 mt of Inferred Mineral Resource at a grade of 1.0% Li2O limited to eight deposits in the Northern and Southern Spodumene Pegmatite Areas (Refer to Table 1 for summary of mineral resources at Rock Tech’s Georgia Lake project).

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.

a. CIM Definition Standards (2014) were used for reporting the Mineral Resources. 

b. The Qualified Person is Dinara Nussipakynova, P.Geo. of AMC. 

c. Cut-off grade for open pit Mineral Resources is 0.30% Li2O. 

d. Open pit Mineral Resources are constrained by the optimization pits shell at a lithium concentrate price of USD 1,100/t with metallurgical recovery of 80% and concentrate grade of 6%. Both cut off use same parameters. 

e. The pit optimization was based on following cost assumptions: 

           i.  Mill feed mining costs of USD 4.5/t and waste mining cost of USD 4.5/t. 

           ii.  Processing costs of USD 25/t and General and Administration costs of USD 15/t. 

           iii.  Slope angle 45-48 degrees. 

f.  Cut-off grade for underground Mineral Resources is 0.60% Li2O based on a USD 45/t mining cost and processing and G&A the same as the open pit. 

g. Underground Mineral Resources are not constrained. 

h. Mineralized Density used as 2.69 t/m3. 

i.  Waste Density used as 2.75 t/m3. 

j.  Drilling results up to 31 July 2022. 

k. The numbers may not compute exactly due to rounding. 

j.  Numbers may not compute exactly due to rounding. 


Samples will be 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 will be determined based on internal zoning of the dikes and the locations of their contacts. Core to be sampled will be cut in half with one half being sent for analysis and the other half remaining in the box for reference. All core will be stored at Rock Tech’s core facility in Beardmore, Ontario. Each sample will be put into its own plastic sample bag with a sample tag and closed with zip ties. About 13% of the samples that will be submitted to Activation Laboratories Ltd. (“Actlabs”) for analysis will be QAQC samples. QAQC samples will be inserted into the sample stream and will consist of a high- and low-grade lithium standards, blank material, and duplicates. Samples will be dropped at Actlabs’ preparation laboratory in Thunder Bay, Ontario for crushing and pulverizing, and will subsequently be 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. Will be used to analyze for lithium. Actlabs is independent of the Company.
