Great Atlantic Now Completing the Final Guidance Hole While Awaiting the Arrival of the BoreDrill from the Netherlands - 100% Owned Golden Promise Gold Property, Central Newfoundland

Vancouver, British Columbia--(Newsfile Corp. - April 24, 2025) - GREAT ATLANTIC RESOURCES CORP. (TSXV: GR) (the "Company" or "Great Atlantic") is pleased to announce its wholly owned subsidiary, Golden Promise Mines Inc., has mobilized diamond drilling equipment to its Golden Promise Gold Property to complete one additional pre-bulk sampling hole, partnering with Novamera Inc., at the gold bearing Jaclyn Main Zone (JMZ). The property is located in central Newfoundland.

"We are now drilling the final of three strategically placed guidance holes-this marks the last step necessary to assist in the precise orientation of the BoreDrill prior to commencing our 2,700-tonne bulk sample, which will target material grading over 10.4 grams of gold per tonne.

This will be the first time in the world that AI-assisted Surgical Mining™ is deployed using directional drilling with a 2.5-meter-wide BoreDrill. If successful, it will represent a major leap forward-not only for Great Atlantic and our development plans at Golden Promise, but for the broader mining sector as a whole.

The custom-built directional drill head is currently en route from Italy, while the BoreDrill itself is on a vessel from the Netherlands. Both are expected to arrive at the port in Newfoundland during the first week of May. We anticipate beginning the bulk sample program within the next couple of months," states CEO Anderson.

The hole will be a steep down-dip hole in the area of the planned 2025 bulk sample site at the JMZ. This will be the third and final of three steep down-dip holes in the area of the planned bulk sample program. The first two down-dip holes were completed during December, 2024.

This drill hole, as with the two late 2024 drill holes, will utilize Novamera's proprietary Guidance Tool and will be managed by Novamera Inc.

Novamera's proprietary Guidance Tool will be again used to provide increased data and knowledge to define the vein's shape, geometry, and continuity. It is used to collect subsurface data to define the geometry of the JMZ vein (s). The Guidance Tool collects data within a 3-4 meter radius of the borehole to create a high-resolution 3D orebody model, which is then used to calculate the optimal drill trajectory for Surgical Mining^TM.
