"Great Atlantic has assembled a prolific and diverse portfolio of 100% owned properties assembled in

both NB & NFLD. Regional work continues in the gold district, and we are developing additional

targets and making new discoveries while advancing the bulk sample at the Jaclyn Main Zone, which

remains our primary focus,"

stated Anderson, CEO.

Four trenches were excavated during June within the southwest region of the Golden Promise

Property in an area of gold anomalies (soil and rock samples). Initial 2024 trenching in this area

uncovered bedrock anomalous for gold and copper.

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 2025 trenches were excavated

within the southwest region of the property within Mineral Licence 036105M, approximately 4 kilometers

northeast of Linda / Snow White gold bearing quartz vein system.

The four trenches were excavated within an area of gold soil anomalies (up to 77 parts per billion gold

(ppb)) and anomalous gold (+/- anomalous copper) in rock samples (glacial float, subcrop and bedrock)

based on previous sampling by Great Atlantic and Golden Promise Mines Inc. Golden Promise Mines

Inc. collected rock samples anomalous for gold +/- anomalous copper from two trenches in this area

during 2024 (see Company News Release of February 12

th

, 2025), including:

2024 Trench #1:

309464 (float): 0.964 grams / tonne (g/t) gold

309466 (subcrop): 0.463 g/t gold and 4,287 ppm copper (0.428% Cu)

309469 (bedrock): 0.481 g/t gold, >6.0 g/t silver and >10,000 ppm copper (> 1% Cu)

2024 Trench #2:

309472 (float): 0.420 g/t gold

309473 (bedrock): 0.323 g/t gold

309474 (float): 0.196 g/t gold and 5,370 ppm copper (0.537% Cu)

Trench No. 1 of the 2025 program was excavated between the two 2024 trenches. Trench No. 2 of 2025

program was excavated west – southwest of 2024 Trench No. 2. The third and fourth 2025 trenches

were excavated approximately 200 meters and 160 meters southwest and south of the second 2025

trench in an area of gold soil anomalies (identified during Great Atlantic's 2018 and 2020 exploration

programs).

Thirty-eight samples were collected during June at the four 2025 trench sites with samples collected from

glacial float boulders excavated from the trenches and from subcrop and outcrop within the trenches.

Most of the samples contain quartz veining (with +/- metasedimentary host rock) and / or sulfide

mineralization consisting mainly of pyrite. Chalcopyrite is present in some samples collected from 2025

Trench No. 2. All samples have been submitted to an independent, certified laboratory for gold and multi-

element analysis. The analytical results are pending.

Five additional rock samples were collected during the June program from the area of 2024 Trench No.

1 which has been backfilled.

Three of these samples were collected from a near surface bedrock

exposure at this trench site (same location as 2024 sample no. 309469 which yielded 0.481 g/t

gold, >6.0 g/t silver and >1% copper). The three 2025 grab samples were collected from the same

narrow (up to approximately 0.4 meters wide) silicified, sheared and sulfide bearing (pyrite and

chalcopyrite) zone as sample 309469.

These samples have also been submitted to an independent,

certified laboratory for gold and multi-element analysis.
