GREAT ATLANTIC SITE SET UP FOR BULK SAMPLING PROGRAM TARGETING EARLY SEPTEMBER AS OFFICIAL START AT ITS 100% OWNED GOLDEN PROMISE GOLD PROPERTY, CENTRAL NEWFOUNDLAND

Great Atlantic Resources Corp.'s wholly owned subsidiary, Golden Promise Mines Inc., has mobilized and set up a specialized large-diameter drill for drilling of a bulk sample at its Golden Promise gold property, located in central Newfoundland.

"Site set-up at the Jaclyn Main zone is now nearly complete. Testing of the world's first-of-its-kind precision mining initiative, utilizing Novamera's technology, is about to begin. The minimal environmental footprint and non-invasive approach to narrow vein mining are expected to significantly reduce all-in sustaining costs (AISC). This positions Great Atlantic at the forefront of mining innovation and as a key player in value creation within Newfoundland's gold sector. As they say, fortune favours the brave," states Christopher Anderson, chief executive officer.

The bulk sampling program is being conducted at the gold bearing Jaclyn Main zone (JMZ), specifically within an area of high-grade gold diamond drilling intercepts. The bulk sample will total up to 1,000 cubic metres (approximately 2,700 tonnes).

The bulk sampling work at the JMZ is being financed in part by co-investment from Digital, Canada's global innovation cluster for digital technologies, as part of a larger project that aims to support data-driven and digital solutions within the mining sector.

The bulk sampling program is being conducted in the west region of the JMZ. Golden Promise Mines completed eight diamond drill holes during September to October of 2024 in the area of the bulk sampling program. The eight holes were designed to target the JMZ between surface and approximately 100 metres (m) of vertical depth. High-grade intercepts from this drilling included (core length) (see the company's news releases of Nov. 19, 2024, Dec. 4, 2024, Jan. 8, 2025, Jan. 14, 2025, and Jan. 20, 2025):

• GP-24-157: 34.47 to 35.00 m (0.53 m): 34.879 grams per tonne (g/t) gold;
• GP-24-160: 78.95 to 79.52 m (0.57 m): 19.121 g/t gold;
• GP-24-161: 82.56 to 83.00 m (0.44 m): 120.89 g/t gold;
• GP-24-162: 109.25 to 109.69 m (0.44 m): 60.206 g/t gold;
• GP-24-163: 37.00 to 37.80 m (0.80 m): 28.023 g/t gold;
• GP-24-164: 54.53 to 55.35 m (0.82 m): 42.708 g/t gold;
• GP-24-164 64.13 to 64.65 m (0.52 m): 39.180 g/t gold.

Three additional close-spaced diamond drill holes were completed during December, 2024, and April, 2025, in this area of the JMZ in preparation for the bulk sample program, the program managed by Novamera Inc. The three drill holes included the use of Novamera's proprietary guidance tool, providing increased data and resource knowledge to define the shape, geometry and continuity of the vein (or veins). The guidance tool collects data within a three to four m radius of the borehole to create a high-resolution 3-D model, which is then used to calculate the optimal drill trajectory for Surgical Mining.

Great Atlantic reported a National Instrument 43-101-compliant inferred resource estimate during late 2018 for the JMZ of 357,500 tonnes at 10.4 g/t gold (119,900 inferred ounces of gold -- uncapped) (see the company's news release of Dec. 6, 2018, and the National Instrument 43-101 technical report on the Golden Promise property, central Newfoundland (revised), filed on SEDAR+ and dated Dec. 4, 2018, by Greg Z. Mosher, MScApp, PGeo, and Larry Pilgrim, BSc, PGeo).

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 (km) 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 or any of the other central Newfoundland gold properties of Golden Promise Mines.

David Martin, PGeo (New Brunswick, and Newfoundland and Labrador), a qualified person as defined by National Instrument 43-101 and vice-president of exploration for Great Atlantic, approved the technical information contained in this news release.
