Great Atlantic Establishes wholly Owned Subsidiary

Golden Promise Mines Inc.

VANCOUVER, British Columbia – September 06, 2023 - GREAT ATLANTIC

RESOURCES CORP. (TSXV.GR) (the “Company” or “Great Atlantic”) is pleased to

announce that it has established a wholly -owned subsidiary named Golden Promise Mines Inc.

into which it will be transferring all of Great Atlantic’s central Newfoundland gold properties

including the Golden Promise Property, the Southwest Golden Promise Property, the West Golden

Promise Property, the South Golden Promise Property, the East Golden Promise Property, the

Coronation Property, the Lynx Property and the Golden Trust Property.

Golden Promise Property

The Golden Promise Property is the Company’s most advanced, highest priority and largest (14

mineral licences totalling 16,525 hectares) property. Great Atlantic acquired the property through

two option agreements and staking and has acquired 100% interest in the property. Multiple gold

bearing quartz veins / quartz vein systems and zones of gold bearing quartz boulders occur within

the property.

One such gold bearing quartz vein system is the Jaclyn Main Zone (JMZ). Great Atlantic reported

a NI 43-101 compliant mineral resource estimate for the JMZ during December 2018 (119,900

ounces of gold - Inferred resource) (see Company news release of December 6th, 2018). Diamond

drilling by Great Atlantic during 2019 - 2021 tested a section of the JMZ and the east region of the

Jaclyn North Zone with high grade gold being intersected including the following intercepts (core

length) (see Company news releases for results of 2019-2021 drilling programs at the Jaclyn

Zone):

Jaclyn Main Zone:

GP-19-138: 113.0 grams / tonne

(g/t) gold over 0.55 meters.

GP-19-139: 15.8 g/t gold over

2.70 meters.

GP-19-140: 2.30 g/t gold over

25.25 meters.

GP-21-149: 238 g/t gold over

0.40 meters.

GP-21-151: 56.8 g/t gold over

0.75 meters.

Jaclyn North Zone:

GP-21-156: 30.6 g/t gold over

0.41 meters

Drilling during 2021 intersected gold mineralization at the Ot ter Brook gold showing in the east

region of the Golden Promise Property. Samples from four holes exceeded 1 g/t gold including

4.95 g/t gold over 0.50 meters core length in drill hole OB -21-9 (see Company news release of

May 31st, 2022). Based on depths and locations of intersected gold bearing intervals, Company

management are interpreting at least four gold bearing veins / structures at / near this showing.

Great Atlantic collected gold bearing rock samples during 2020 at the Otter Broo k gold showing

from outcrop, subcrop and float. Eight of 11 rock samples collected during 2020 at this showing

returned gold values in the 0.719 – 5.758 g/t range. An outcrop grab sample returned the highest

value of 5.758 g/t gold (see Company news release of December 3rd, 2020).

Multiple 2017 Great Atlantic quartz samples from different regions of the Golden Promise

Property exceeded 1 ounce / ton gold (see Company news releases for results of 2017-2022 work

at the Golden Promise property).

Great Atlantic acquired the Golden Trust, Southwest Golden Promise, East Golden Promise, West

Golden Promise, South Golden Promise, Lynx and Coronation properties during 20 19 and 2020

through staking.

Golden Trust

The property, which covers an area of 2,400 hectares, is located approximately 44 kilometers

southwest of the Golden Promise Property and one kilometer north of the Valentine Gold Project

of Marathon Gold Corp. Great Atlantic confirmed gold soil geochemica l anomalies in multiple

areas within the northern region of the Golden Trust Property during 2020 and 2022. The initial

2020 reconnaissance soil sampling identified gold soil anomalies in this region of the property

with samples collected adjacent to a trail returning up to 52 parts per billion (ppb) gold (see

Company news release of January 27th, 2021). Fifty-three soil samples were collected during the

4

2022 program along two north-south sample lines east and west of some 2020 samples. Ten of the

53 soil samples (approximately 19% of the samples) returned anomalous values of 5-72 ppb gold

of which five samples (approximately 9% of the samples) returned 10-72 ppb gold (see Company

news release of February 17th, 2023).

Southwest Golden Promise Property

The property, which covers an area of 1, 750 hectares, is located adjacent to the southwest region

of the Company’s Golden Promise Property. Initial 2019 prospecting by Great Atlantic located

gold bearing quartz vein rubble (possible subcrop). A sample from multiple pieces of quartz vein

rubble at one location returned 3.14 g/t gold identifying a target area (see Company news release

of May 7th, 2020).

East Golden Promise Property

The property, which covers an area of 1,125 hectares, is located adjacent to the east region of the

Golden Promise Property. The property covers areas of reported gold bearing rock samples ,

including two float samples reported to return 0.40 and 0.41 g/t gold (Copeland and Newport,

2005). Local Great Atlantic rock and soil samples collected during 2022 returned anomalous

gold values, up to 0.084 g/t gold in rock samples of loose material (subcrop) near bedrock and

up to 137 ppb in soil samples (see Company news releases of December 7th, 2022, and April 18th,

2023).

West Golden Promise Property

The property, which covers an area of 1,425 hectares, is located adjacent to the west region of the

Golden Promise Property. A 2005 soil sample collected within 100 meters of the east boundary

5

of the property was reported to return a highly anomalous value of 0.559 parts per million (ppm)

gold (Sparkes, 2006).

South Golden Promise Property

The property, which covers an area of 450 hectares, is located adjacent to the south region of the

Golden Promise Property. A 2008 soil sample reported approximately 113 meters north of the

property (in the Company’s Golden Promise Property) was reported to return a highly

anomalous value of 0.388 ppm gold (Morgan, 2008).

Lynx Property

The property, which covers an area of 1,525 hectares, is located approximately 12 kilometers east

of the northern region of the Golden Promise Property. The property covers the area of a reported

2004 quartz float sample which was reported to returned 17 g/t gold, 1.74 % copper and >1%

antimony (Copeland and Newport, 2005) and the Lynx Pond pyrite -gold mineral occurrence

(Newfoundland and Labrador Department of Industry, Energy and Tec hnology, Mineral

Occurrence Database).

Coronation Property

The property, which covers an area of 500 hectares, is located approximately 14 kilometers east

of the southern region of the Golden Promise Property. The property covers the Coronation Lake

South #1 and Coronation Lake South #2 gold -silver-molybdenum-copper mineral occurrences

(Newfoundland and Labrador De partment of Industry, Energy and Technology, Mineral

Occurrence Database). Mineralization reported during 1975 (Dimmell, 1975) include:

• A 1975 diamond drill hole was reported to intersect 0. 025 ounces / ton gold over 3 feet

core length (Dimmell, 1975).

• A 1975 float sample was reported to return 0.65% copper, 0.25% molybdenum and 0.015

ounces / ton gold (Dimmell, 1975).

Gold soil anomalies are reported within the property including 0.43 ppm gold, 0.152 ppm gold

and 0.112 ppm gold (Copeland and Newport, 2005).

The eight central Newfoundland gold properties of Great Atlantic discussed in this news release

are located within the Exploits Subzone of the Newfoundland Dunnage Zone. Recent significant

gold discoveries within the Exploits Subzone include those of Marathon Gold Corp. (TSX.MOZ)

at the Valentine Gold Project, Sokoman Minerals Corp. (TSXV.SIC) at the Moosehead Gold

Project and New Found Gold Corp. (TSXV.NFG) at the Queensway Project. Readers are warned

that mineralization at the Valentine Gold Project, Moosehead Gold Project, and Queensway

Project is not necessarily indicative of mineralization the Golden Promise Property.

Readers are warned that historic information referred to in this news release have not been verified
