Quebec (Figure 1). 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%

Li2O and 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 Lith ium

Deposit of Sa y ona Mining (ASX: SY A) 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 (https://bit.ly/3qxcgZM).

Figure 1: Regional location of the Chubb Lithium Property within the La Corne Pluton.

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 monzodior ite 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 t o 6 m e t r e s t h i c k s o f a r ,

oriented northwest and vary in length from 25 to 250 metres. The pegmatites are composed

o f q u a r t z , a l b i t e a n d / o r c l e a v e l a n d i t e , K - f e l d s p a r , m u s c o v i t e , 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 i ntersected

3.7m grading 1.68% Li2O, 2.74m grading 1.00% Li2O and 2.4m grading 1.25% Li2O.

Commentary from the CEO

Great Thunder’s President and CEO, Mr. Blair Naughty, said, “While we continue to focus on

gold in the Fenelon camp, Great Thunder is in an enviable position to have the Chubb Lithium

Property in a prolific lithium‐bearing pegmatite field, close to infrastructure and close to the

development of the first possible lithium mines in Canada during the inevitable need for electric

vehicles. We look forward to continuing our exploration efforts with an upcoming drill program

in the spring of 2021.”
