GREAT ATLANTIC TRENCHING PROGRAM UNDERWAY AT 100% OWNED GOLDEN PROMISE GOLD PROPERTY, CENTRAL NEWFOUNDLAND

Great Atlantic Resources Corp.'s wholly owned subsidiary, Golden Promise Mines Inc., has mobilized an excavator to begin trenching at its Golden Promise gold property, located in central Newfoundland.

Excavator trenching will be conducted within the southwest region of the 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 initial 2025 trenches will be excavated approximately four kilometres northeast of Linda/Snow White gold-bearing quartz vein system.

Golden Promise Mines has approval from the Newfoundland and Labrador government for up to seven trenches within this southwest region of the Golden Promise property, all within mineral licence 036105M (see company news release dated May 21, 2025). The approved trenches are in two target areas in this region.

The initial trenches will be excavated within an area of gold soil anomalies (up to 77 parts per billion gold (ppb)) and anomalous gold (plus/minus anomalous copper) in rock samples (glacial float, subcrop and bedrock) based on previous sampling by Great Atlantic and Golden Promise Mines. Golden Promise Mines collected rock samples anomalous for gold plus/minus anomalous copper from two trenches in this area during 2024 (see company news release of Feb. 12, 2025), including:

2024 trench No. 1:

• 309464 (float): 0.964 gram/tonne (g/t) gold;
• 309466 (subcrop): 0.463 g/t gold and 4,287 ppm (parts per million) copper (0.428 per cent Cu);
• 309469 (outcrop): 0.481 g/t gold, greater than 6.0 g/t silver and greater than 10,000 ppm copper (greater than 1 per cent Cu).

2024 trench No. 2:

• 309472 (float): 0.420 g/t gold;
• 309473 (outcrop): 0.323 g/t gold;
• 309474 (float): 0.196 g/t gold and 5,370 ppm copper (0.537 per cent Cu).

The initial two trenches of the current program will include a trench between the two 2024 trenches and a trench west of 2024 trench 2. The third and fourth planned trenches will be located further south within approximately 250 metres of 2024 trench No. 2 in an area of gold soil anomalies (identified during Great Atlantic's 2018 and 2020 exploration programs).

Three trenches are also planned during 2025 approximately one kilometre farther north in an area of gold soil anomalies identified during 2024 along a reconnaissance soil sampling traverse, including three consecutive samples (approximately 25 metres sample spacing) which returned anomalous gold values of 44 ppb (parts per billion), 53 ppb and 83 ppb. Some 2024 soil samples in this area also returned anomalous values for copper (up to 121 parts per million (ppm)), molybdenum (up to 44 ppm) and antimony (up to 28 ppm).

The Golden Promise property is the largest and most advanced of six central Newfoundland gold properties owned by Golden Promise Mines and located within the Exploits Subzone of the Newfoundland Dunnage zone. One of these properties (Golden Trust) is located within one kilometre 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.
