Great Atlantic Receives Additional Permit

Diamond Drilling Approval for Up To 33 Holes

for the Jaclyn Zone at its 100% Owned Golden

Promise Property, Central Newfoundland

Vancouver, British Columbia--(Newsfile Corp. - May 28, 2025) -

GREAT ATLANTIC RESOURCES

CORP. (TSXV: GR) (the "Company" or "Great Atlantic")

is pleased to announce its wholly owned

subsidiary, Golden Promise Mines Inc., has received approval from the Newfoundland and Labrador

government for diamond drilling at the Golden Promise Property. The drilling approval is for up to 33 drill

holes (approximately 8,000 meters) at the Jaclyn Zone.

Golden Promise Mines property contains multiple gold bearing quartz veins / vein systems with

high grade gold. Company drilling between 2019-2024 resulted in multiple drill intercepts

exceeded 1 ounce gold / tonne.

The drilling approval allows for diamond drilling (up to 33 drill holes) in the areas of the gold – bearing

Jaclyn Main Zone (JNZ); the gold – bearing Jaclyn North Zone (JNZ); a target immediately north of the

JMZ; and the area east-northeast of the JNZ. The Company is planning diamond drilling during 2025 –

2026 under this approval. The drilling approval expires on April 4, 2027

Great Atlantic / Golden Promise Mines Inc. intersected high-grade quartz veins at the JMZ during

2019, 2021 and 2024 drilling programs including numerous intercepts exceeding 1 ounce / tonne

gold (see news releases at the Company's website) and reported a National Instrument 43-101

compliant inferred resource estimate during late 2018 for the JMZ of 357,500 tonnes at 10.4

grams / tonne (g/t) gold (119,900 inferred ounces of gold - uncapped) (see the Company's news

release of December 6, 2018).

The drilling approval allows for drill holes testing the central to east regions of the JMZ in an area of less

previous diamond drilling. The objective of this planned drilling is to increase the JMZ's inferred

resources. Following completion of this drilling Great Atlantic plans to generate an updated NI 43-101

technical report and resource estimate.

The drilling approval allows for drill holes testing for gold bearing quartz veins immediately north of the

JMZ along an apparent northeast striking structural zone (based on aeromagnetic geophysical data)

which connects with the JMZ.

The drilling approval allows for drill holes in the eastern region of the JNZ and east-northeast of the JNZ.

Diamond drilling by Great Atlantic during 2020 and 2021 indicated the JNZ gold bearing vein system to

be open to the east-northeast.

The two eastern-most 2020 and 2021 drill holes intersected gold

bearing veins including 30.6 g/t gold over 0.41 meters core length in drill hole GP-21-156 (see the

Company's news release of April 12

th

, 2022).

Rock samples collected during 2017 and 2020 in the area of drill hole GP-21-156 from multiple

gold-bearing quartz boulders yielded high grade gold values including samples returning 157 g/t,

162 g/t, 208 g/t and 332 g/t gold (see Company news releases).

These samples are located within

a 300-meters long zone of gold-bearing quartz vein boulders.

The Golden Promise Property is the largest and most advanced of six central Newfoundland gold

properties owned by Golden Promise Mines Inc. and located within the Exploits Subzone of the

Newfoundland Dunnage Zone.

One of these properties (Golden Trust) is located within one

kilometer of the Valentine Gold Mine of Calibre Mining Corp. which is also located within the

Exploits Subzone.

Readers are warned that mineralization at the Valentine Gold Mine is not

necessarily indicative of mineralization at the Golden Promise Property or any of the other central

Newfoundland gold properties of Golden Promise Mines Inc.
