Great Atlantic Completes First Phase of 2026 Trenching Program at 100% Owned Golden Promise Property

Central Newfoundland Vancouver, British Columbia--(Newsfile Corp. - June 12, 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 completed the first phase of its 2026 trenching program at the Company's 100% owned Golden Promise Property, central Newfoundland. Three trenches were excavated within the southwest region of the Golden Promise Property testing an area of multi-element soil geochemical anomalies, including gold anomalies. Rock samples collected at the trench sites have been submitted for gold and multi-element analysis. 2026 Trench No. 2 - Golden Promise Property (Licence 036105M) To view an enhanced version of this graphic, please visit: https://images.newsfilecorp.com/files/3027/301228_0156603b44a33a78_002full.jpg Rock Sampling at 2026 Trench No. 1 - Golden Promise Property (Licence 036105M)  To view an enhanced version of this graphic, please visit: https://images.newsfilecorp.com/files/3027/301228_0156603b44a33a78_003full.jpg "Completion of the first trenching phase represents another important milestone in our 2026 exploration program at Golden Promise," states Anderson, CEO 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 multi-element soil geochemical anomalies were identified by Golden Promise Mines during 2024 along a northeast - southwest reconnaissance soil sampling traverse.

S oil samples along one section of the traverse returned anomalous gold values of 44 parts per billion (ppb), 53 ppb and 83 ppb while some samples returned anomalous values for silver (up to 3.9 parts per million (ppm)), 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 meters long.

Exposed bedrock is common within each of the trenches with overburden being less than one meter thick in numerous locations. Some sections of bedrock have been thoroughly cleaned off using a high-pressure water sprayer. The trenches are orientated 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.
