Great Thunder Commences Drilling on the

Southern Star Property in the Fenelon Gold Camp

Vancouver, BC, March 24th, 2021 – Great Thunder Gold Corp. (CSE: GTG, OTC: GTGFF, FSE:

M4KQ-FF) ( “ G r e a t T h u n d e r ” o r t h e “ C o m p a n y ” ) i s p l e a s e d t o a n n o u n c e t h a t i t s i n a u g u r a l

drilling program on its Southern Star Property (“Southern Star” ) has commenced. The

Southern Star is located along the Lower Detour deformation zone, part of the Sunday Lake-

D e t o u r c r u s t a l s c a l e s t r u c t u r a l d o m a i n r e c o g n i z e d f o r i t s r e l a tion to gold deposits in east

central Quebec (Figure 1).

Property. The targets that will be drilled are located approxim ately 6.5km south of

Wallbridge Mining’s Fenelon Deposit and 9km south of their Tabasco and Area 51 gold zones

(Figure 2).

Southern Star Targets

The 2021 first-pass drill program will consist of 4 diamond drill holes targeting depths of 600

metres per hole for a total of about 2,400 metres. Drill targets have been selected based on the

conductive plate modelling carried out by Campbell and Walker Geophysics. The ‘ A’ conductor

was initially targeted in a 1986 drill campaign; however, the n ewly interpreted 3D model

demonstrated that the targets were not properly penetrated. The ‘ A ’ c o n d u c t o r i s a h i g h -

priority target in this Phase 1 program.

The ‘B’ conductor (in the centre of Figure 3) is flat lying and i s b e l i e v e d t o b e p r o p e r l y

penetrated in past drill programs. This conductor will not be t argeted in the maiden drill

program.

The ‘C’ conductor has never been drilled and will be a focus for this Phase 1 drill program.

System in the third quarter of 2021.

Commentary from the CEO

“We are excited to launch our inaugural drilling program on Southern Star. New geophysical

interpretation of conductive pla tes along the Lower Detour defo rmation zone and the fact

that historical drilling failed t o i n t e r s e c t t h e s e f a v o u r a b l e horizons for mineralization

provides opportunity for success for Great Thunder. Wallbridge Mining has demonstrated

t h a t d r i l l i n g b e y o n d t h e c o n f i n e s o f t h e i r d e p o s i t m o d e l c o n t i nu e s t o i m p r o v e t h e o v e r a l l
