Great Thunder Reports 1.48% Li2O over 12.7m at its Chubb Lithium Project in Quebec






Chubb Lithium drill program extends pegmatite dyke along strike and depth


Great Thunder Gold Corp. (CSE: GTG) (OTC Pink: GTGFF) (FSE: M4KQ) would like to provide final drill results from its drilling activities in Quebec at its Chubb Lithium Project.


Chubb Lithium Project


On the Chubb Lithium Project, Great Thunder completed 15 diamond drill holes totalling 2,283 metres. Assays have been received from a total of 423 samples from all drill holes. Highlights of the results received to date include 1.48% Li2O over 12.7m and 1.16% Li2O over 9.8m at the Main Dyke (see Table 1). These are the widest and highest-grade intercepts to date where thickening of the Main Dyke is appearing to extend south along strike and at depth.

All the assays were performed by ALS Laboratory of Val d’Or using Na2O fusion and ALS’s super traces ICP-MS methodology.


The Chubb Lithium project is located in the prolific La Corne pegmatite field located km north of Val d’Or, QC (Figure 1). The La Corne pegmatite field is host to North American Lithium’s deposit with reported proven and probable reserves of 17.06 Mt grading 0.94% Li2O and measured and indicated resources of 33.24 Mt grading 1.19% Li2O ( The La Corne pegmatite field also hosts the Authier Lithium Deposit of Sayona Mining which is estimated to contain measured and indicated resources of 17.18 Mt grading 1.01% Li2O and inferred resources of 3.76Mt grading 0.98% Li2O

To date three parallel pegmatitic dykes oriented south southeast are located on the Property, namely the Main Dyke, Dyke 2 and Dyke 3. Eight holes were completed on the Main Dyke, 5 holes were completed on Dyke 2 and 2 holes were completed on Dyke 3.

We are extremely pleased with the lithium results from our Phase 1 drill program at the Chubb Property, said CEO Blair Naughty. “Drilling has not only confirmed historical results but has improved on the grade and width from Great Thunder’s drill program completed in 2017. This round’s best drill hole ended in mineralization and could not go further due to weather conditions. Winter weather will enable our drillers to continue drilling the extension of this area. We look forward to analyzing the results and moving forward with a Phase 2 program in this prolific lithium camp.”


Potential Spinout of Lithium Projects


Additionally, the Company would like to update its shareholders about the potential transfer of its Canadian lithium exploration projects to a new subsidiary that was previously announced in a news release dated October 21st, 2020.
