GREAT ATLANTIC COMPLETES FIRST PHASE OF 2026 TRENCHING PROGRAM AT 100% OWNED GOLDEN PROMISE PROPERTY

Great Atlantic Resources Corp.'s wholly owned subsidiary, Golden Promise Mines Inc., has completed the first phase of its 2026 trenching program at the company's 100-per-cent-owned Golden Promise property, central Newfoundland. Three trenches were excavated within the southwestern region of the Golden Promise property testing an area of multielement soil geochemical anomalies, including gold anomalies. Rock samples collected at the trench sites have been submitted for gold and multielement analysis.

"Completion of the first trenching phase represents another important milestone in our 2026 exploration program at Golden Promise," stated Christopher Anderson, chief executive officer of Great Atlantic. "The work is helping refine our understanding of known gold-bearing zones while supporting the advancement of additional targets across the property. We remain encouraged and look forward to the next stages of our work program on the property."

Golden Promise Mines excavated the three trenches at the Golden Promise property during late May/early June (within mineral licence 036105M) in an area of the soil geochemical anomalies. The multielement soil geochemical anomalies were identified by Golden Promise Mines during 2024 along a northeast-southwest reconnaissance soil sampling traverse. Soil samples along one section of the traverse returned anomalous gold values of 44 parts per billion, 53 ppb and 83 ppb while some samples returned anomalous values for silver (up to 3.9 parts per million), copper (up to 121 ppm), molybdenum (up to 44 ppm), antimony (up to 28 ppm), zinc (up to 225 ppm), arsenic (up to 172 ppm) and/or vanadium (up to 920 ppm). The 2024 soil samples were analyzed by Eastern Analytical Ltd. for gold by fire assay AA and for 34 elements by four-acid digestion and ICP-OES analysis.

The three trenches are approximately 60, 70 and 105 metres long. Exposed bedrock is common within each of the trenches with overburden being less than one metre thick in numerous locations. Some sections of bedrock have been thoroughly cleaned off using a high-pressure water sprayer. The trenches are oriented northwest-southeast and are approximately perpendicular to the reported bedrock geology contacts in this area between the Lawrence Harbour formation and Stanley Waters formation (Rogers et al., 2005), both part of the Victoria Lake supergroup. Some gold-bearing quartz veins/quartz vein systems within the Golden Promise property occur near the contacts of these two formations.

Golden Promise Mines collected 29 rock samples during May/early June from the three trenches. These samples include samples from excavated rubble, subcrop and bedrock. The samples have been submitted to Eastern Analytical (located in Springdale, Nfld.) for gold analysis (fire assay (30 grams) with AA finish) and multielement (34 elements) analysis (four-acid digestion with ICP-OES analysis). Eastern Analytical is a commercial laboratory that is ISO/IEC 17025 accredited and completely independent of Great Atlantic and Golden Promise Mines. The analytical results are pending.

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 2026 trenching program at licence 036105M was conducted approximately five kilometres northeast of gold-bearing Linda/Snow White gold-bearing quartz vein system.

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

Please see the company's website for news releases reporting previous work on the Golden Promise property. The 2026 trenching program at licence 036105M was supervised by a qualified person. Previous 2017-2025 programs at Golden Promise were supervised by a qualified person.
