Feb 22, 2021

Great Thunder Gold Corp. has filed an updated National Instrument 43-101 Technical Report relating to its Chubb Lithium property on SEDAR. The report recommends drilling on the three main dykes of the Property.

The Chubb Lithium Property

The Chubb Lithium property is located 25 km north of Val d'Or, Quebec. It is hosted within the La Corne Pluton which is also host to North American Lithium's deposit with reported proven and probable reserves of 17.06 Mt grading 0.94% Li2and measured and indicated resources of 33.24 Mt grading 1.19% Li2O (http://na-lithium.com/projects). The Chubb Lithium property is also close to the Authier Lithium Deposit of Sayona Mining (ASX: SYA) 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% Li2(https://bit.ly/3qxcgZM).

The Chubb Lithium property consists of 35 contiguous mineral claims for a total area of 1,509 hectares. The property geology is dominated by quartz monzodiorite and metasomatized quartz diorite (tonalite). A swarm of spodumene-rich pegmatite dykes intrude fractures and small faults within the plutonic rocks. The pegmatite dykes are 1 to 6 metres thick so far, oriented northwest and vary in length from 25 to 250 metres. The pegmatites are composed of quartz, albite and/or cleavelandite, K-feldspar, muscovite, with 5% to 25% spodumene. There are three important pegmatite dykes containing spodumene mineralization (Main Dyke, Dyke #2, and Dyke #3) (Figure 2).

Great Thunder drilled 3 holes for 306m in 2017 on the Property. Highlights included 1.33% Li2O over 5.3m in hole C-17-01. Diamond drilling by Wrightbar Mines in 1994 intersected 3.7m grading 1.68% Li2O2.74m grading 1.00% Li2O and 2.4m grading 1.25% Li2O.
