Great Atlantic Discovers New Gold - Copper Zone at 100% Owned Golden Promise Property Central Newfoundland
Great Atlantic Discovers New Gold - Copper
Zone at 100% Owned Golden Promise Property
Central Newfoundland
Vancouver, British Columbia--(Newsfile Corp. - September 10, 2026) -
GREAT ATLANTIC
RESOURCES CORP. (TSXV: GR) (the "Company" or "Great Atlantic")
is pleased to announce its
wholly-owned subsidiary, Golden Promise Mines Inc. ("Golden Promise Mines"), has received analyses
for some rock samples collected during 2025 at the Company's 100% owned Golden Promise Property,
central Newfoundland.
The results further confirm gold and copper mineralization in bedrock
within a narrow zone in the southwest region of the property. The mineralized zone was initially
discovered during a 2024 trenching program.

Excavator trenching by Golden Promise Mines during 2024 exposed a narrow sulfide being zone
(including pyrite and chalcopyrite) with quartz veining and exhibiting silicification and shearing. The zone
was exposed in the northern part of the eastern - most trench.
The initial 2024 rock grab sample
(sample no. 309469) from this zone returned 481 parts per billion (ppb) gold (0.481 grams / tonne
(g/t) Au) while returning greater than 10,000 parts per million (ppm) for copper (>1% Cu) and
returning greater than 6 ppm silver
(see Company news releases of February 12, 2025; and
September 4, 2025). The zone is up to 0.4 meters wide in the bedrock exposure, trends northeast -
southwest and is subvertical. The trench was subsequently backfilled although the bedrock exposure with
the gold and copper bearing zone extends to surface and was left exposed.
Three additional bedrock grab samples were collected from the gold and copper bearing zone during
2025. These samples were collected along an approximately 4 meters long section of the zone. The
samples confirmed copper and gold mineralization with +/- anomalous silver. The three 2025 bedrock
grab samples returned:
36105-25-16:
1,008 ppb gold (1.008 g/t Au) and 155 ppm copper
36105-25-47:
807 ppb gold (0.807 g/t Au), >10,000 ppm copper (>1% Cu) & >6 ppm silver
36105-25-48:
443 ppb gold (0.443 g/t Au) and 680 ppm copper
A 2025 sample (36105-25-49) from a piece of subcrop on top of the same bedrock exposure
returned an anomalous gold value of 370 ppb (0.370 g/t gold).

The gold and copper bearing zone discussed in this news release has not been traced along its
projected strike. Management of Golden Promise Mines are planning work within the area of this
mineralized zone including geophysical surveys and additional trenching.
The Golden Promise Property hosts gold bearing quartz veins in various regions of the property,
including the Jaclyn Zone quartz vein systems, Shawn's Shot quartz vein, Otter Brook occurrence, Linda /
Snow White quartz vein system and the Gabbro Zone occurrence. The property is located within the
Exploits Subzone of the Newfoundland Dunnage Zone.
It is located approximately 50 kilometers
northeast of the Valentine Gold Mine of Equinox Gold Corp.
(
TSX: EQX, NYSE: EQX) which is
also located within the Exploits Subzone.
The Golden Promise Property is the largest and most
advanced of seven central Newfoundland gold properties owned by Golden Promise Mines.
One of
these properties (Golden Trust) is located within one kilometer of the Valentine Gold Mine of
Equinox Gold Corp.
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.

The 2024 and 2025 rock samples discussed in this news release were analyzed by Eastern Analytical
Ltd., a certified laboratory independent of Golden Promise Mines and Great Atlantic. Sample 309469
was analyzed for gold by the Total Pulp Metallics method. This involved crushing the sample to -10 mesh
and pulverizing to 95% -150mesh. The sample was then weighed and screened 150mesh. The
+150mesh fraction was fire assayed for gold (148 ppb Au) and a 30-gram subsample of the -150mesh
fraction was fire assayed for gold (482 ppb Au). A calculated weighted average of total gold was also
reported (481 ppb Au). The four 2025 rock samples discussed in this news release were analyzed for
gold by fire assay - AA (30-gram subsamples from -150mesh pulverized fractions). These 2024 and
2025 samples were also analyzed for 34 elements (including silver and copper). This involved total
dissolving of 200mg subsamples from the pulverized fractions and analysis by ICP-OES. The upper
analytical limit was 10,000 ppm for copper and 6 ppm for silver. Golden Promise Mines plans to re-
submit sample nos. 309469 and 36105-25-47 for copper and silver assay.
Readers are warned that pre-2017 historic results stated in Figure 1 have not been verified by Great
Atlantic or Golden Promise Mines.
