GREAT ATLANTIC COMMENCES 2026 FIELD PROGRAM TO ADVANCE HIGH PRIORITY TARGETS AT GOLDEN PROMISE

Great Atlantic Resources Corp.'s wholly owned subsidiary Golden Promise Mines Inc. has begun the 2026 exploration program at its Golden Promise gold property, located in the central Newfoundland gold belt. Prospecting and geochemical sampling are under way within the southwestern region of the property in an area of gold geochemical anomalies (soil and rock samples).

"The 2026 program at Golden Promise is fully under way," stated Christopher Anderson, chief executive officer of Great Atlantic. "We are advancing on multiple fronts simultaneously: trenching and follow-up sampling across high-priority gold and copper targets in the southwest, expanded work programs across the east-central licences, and continued evaluation of the Jaclyn, Linda/Snow White and Gabbro zones. Golden Promise sits in one of the most prospective gold belts in North America, and we believe this property has the geological footprint to deliver meaningful discoveries. Shareholders can expect a steady stream of news flow as the season progresses."

Prospecting and rock geochemical sampling are currently being focused within an approximately one-kilometre-by-a-half-kilometre target area within the southwestern region of the Golden Promise property (within licence 036105M). Within the northern part of this target area is an area of soil geochemical anomalies identified by Golden Promise Mines during 2024 reconnaissance sampling. The 2024 sampling along a reconnaissance traverse included anomalies for gold (up to 83 parts per billion), silver (up to 3.9 parts per million), molybdenum (up to 44 ppm), antimony (up to 28 ppm), copper (up to 121 ppm) and vanadium (up to 920 ppm). The 2024 soil samples were analyzed by Eastern Analytical Ltd. for gold by fire assay and multielement by four-acid digestion and ICP-OES analysis. The company is planning three trenches in this area of these soil anomalies during May and June of 2026 (see company news release of April 10, 2026). Additional soil samples were collected during 2025 within this area of which the analytical results are pending.

Within the southern part of this target area are gold soil geochemical anomalies and gold-bearing rock samples identified by Great Atlantic and Golden Promise Mines, including gold-bearing rock samples collected from two 2024 trench sites (see company news release of Feb. 12, 2025).

These samples included the following.

2024 trench No. 1:

• 309464 (float): 0.964 gram per tonne gold;
• 309466 (subcrop): 0.463 g/t gold and 4,287 ppm 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).

Golden Promise Mines conducted excavator trenching during 2025 within licence 036105M, two trenches of which were excavated adjacent to 2024 trenches 1 and 2. Analytical results are pending for 40 rock samples collected within and adjacent to the 2025 trenches.

Planned prospecting and rock soil geochemical sampling in June will focus on the east-central region of the Golden Promise property within an area of reported gold geochemical anomalies (rock and soil samples) within mineral licence 034704M. Trenching is also planned for this area in June with up to five trenches planned (see company news release of April 10, 2026). Some rock samples collected by Rubicon Mineral Corp. during 2002 to 2005 in this target area were reported to yield anomalous gold values including two quartz vein float samples reported to return gold values of 168 ppb and 109 ppb and a siltstone float sample reported to return 431 ppb gold (0.431 g/t) (Copeland and Newport, 2004; and Copeland and Newport, 2005). Anomalous soil samples from this target area included a sample reported to return 184 ppb gold (Copeland and Newport, 2005). Neither Great Atlantic nor Golden Promise Mines have verified these anomalous samples.

Planned prospecting and rock soil geochemical sampling will include at least 10 other mineral licences within the Golden Promise property, being conducted in target areas for gold exploration identified by company management. This will include work in the southern area of the property in the areas of the Linda/Snow White and Gabbro zone gold occurrences, and the central to northern regions of the property including peripheral to Jaclyn zone gold-bearing quartz vein systems.

The Golden Promise property hosts gold-bearing quartz veins in various regions of the property, including the Jaclyn zone, Shawn's Shot vein, Otter Brook showing, Linda/Snow White quartz vein system and the Gabbro zone occurrence. Great Atlantic reported a National Instrument 43-101-compliant inferred resource estimate during late 2018 for the Jaclyn Main zone of 357,500 tonnes at 10.4 grams per tonne gold (119,900 inferred ounces of gold -- uncapped).

The Golden Promise property is located within the Exploits subzone of the Newfoundland Dunnage zone. The Golden Promise property is located approximately 50 kilometres northeast of the Valentine gold mine of Equinox Gold 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.

Please see the company's website for news releases reporting previous work on the Golden Promise property. Previous 2017 to 2025 programs at Golden Promise were supervised by a qualified person.
