Great Atlantic begins Phase II trenching at Golden Promise

Central Newfoundland Vancouver, British Columbia--(Newsfile Corp. - June 22, 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 commenced its targeted 2026 Phase II trenching program at the Company's 100% owned Golden Promise Property, central Newfoundland.

"The program is focused on a priority gold bearing target zone as we refine and build upon information generated during previous phases of work.

We look forward to continuing exploration on the property and providing further updates as results become available." The Phase II trenching program is being conducted within east-central region of the Golden Promise Property (within Licence 034704M). Gold geochemical anomalies (soil and rock samples) are reported in this target area. Some rock samples collected by Rubicon Mineral Corp. during 2002-2005 in this target area were reported to yield anomalous gold values including two quartz vein float samples reported to return gold values of 168 parts per billion (ppb) and 109 ppb and a siltstone float sample reported to return 431 ppb gold (0.431 grams / tonne) (Copeland and Newport, 2004; and Copeland and Newport, 2005).

Anomalous soil samples from this target area included a sample reported to return 194 ppb gold (Copeland and Newport, 2005). Neither Great Atlantic nor Golden Promise Mines have verified these anomalous samples.

The bedrock geology in the area of the planned trenches is reported to be that of the Stanley Waters Formation (of the Victoria Lake Supergroup) with contacts of the Stanley Waters Formation and the Lawrence Harbour Formation adjacent to the area of planned trenches (Rogers et al., 2005). Some gold bearing quartz veins / quartz vein systems within the Golden Promise Property occur near the contacts of these two formations. These trenches will also be located within various parts of a zone of relatively higher resistivity (interpreted by Company management to be the Stanley Waters Formation) adjacent to areas of lower resistivity (interpreted by Company management to be the Lawrence Harbour Formation which contains black shale).

This is based on a reported 2003 airborne geophysical survey by Rubicon Mineral Corp. (Copeland and Newport, 2004). Some trenches will also be located within areas of magnetic anomalies based on the same 2003 geophysical survey. 2026 Planned Trench Map - Golden Promise Property To view an enhanced version of this graphic, please visit: https://images.newsfilecorp.com/files/3027/302224_f09d2274d48af964_004full.jpg 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 Phase II trenching program is being conducted approximately 2 kilometers northwest of the Otter Brook gold occurrence (Newfoundland and Labrador Department of Energy and Mines, Mineral Occurrence Database).

Great Atlantic confirmed gold bearing veins in the area of the Otter Brook occurrence during 2021 prospecting and diamond drilling (see Company news releases reporting this work). Readers are warned that mineralization at the Otter Brook occurrence is not necessarily indicative of mineralization in the area of the 2026 Phase II trenching program. The Golden Promise Property is located within the Exploits Subzone of the Newfoundland Dunnage Zone.

It is located approximately 50 kilometers 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 kilometer 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.
