Great Atlantic Completes First Three Holes of 2024 Diamond Drilling Program, Gold Bearing Veins Intersected at the Jaclyn Main Zone, 100% Owned Golden Promise Gold Property - Central Newfoundland

Vancouver, September 24, 2024 - Great Atlantic Resources Corp. (TSXV: GR) (the "Company" or "Great Atlantic") is pleased to announce its wholly owned subsidiary, Golden Promise Mines Inc., has completed the first three holes of the 2024 diamond drilling program at its Golden Promise Gold Property, located in central Newfoundland. Sulfide bearing quartz veins with visible gold were intersected in two holes while a fracture zone with sulfide bearing quartz vein pieces was intersected in the third hole.

The fully funded drill program (nine drill holes planned and estimated 900 total meters) is being conducted at the gold-bearing Jaclyn Main Zone (JMZ) in the area of a planned bulk sample.

The drilling program is being conducted within the west region of the JMZ targeting gold bearing veins to approximately 100 meters vertical depth. The first three holes were drilled on the same northwest - southeast trend to intersect the steeply dipping JMZ. The first two holes (GP-24-157 and GP-24-158) were collared approximately one meter apart. Drill hole GP-24-157 was drilled slightly northwest (approximately 347 degrees) at a dip of approximately 46 degrees while hole GP-24-158 was drilled slightly northwest (approximately 346 degrees) at a dip of approximately 61 degrees. Drill hole GP-24-159 was collared approximately 12 meters slightly northwest of hole GP-24-157, also being drilled slightly northwest (approximately 344 degrees) at a dip of approximately 50 degrees. The three holes totalled 204.5 meters.

Drill hole GP-24-157 intersected a sulfide bearing quartz vein at 34.47-35.00 meters (0.53 meters core length). Four pin-size grains of visible gold were noted in this vein by a Qualified Person. Drill hole GP-24-158 intersected a sulfide bearing quartz vein at 45.35-45.94 meters (0.59 meters core length). One pin-size grain of visible gold was noted in this vein by a Qualified Person. Drill hole GP-24-159 intersected a fracture zone (estimated to be less than 0.5 meters core width) with local pieces of sulfide bearing quartz vein material. Company management are interpreting this fracture zone with some quartz vein pieces and the quartz veins of holes 157 and 158 to be the same steeply dipping vein / vein system / structure. Drill core samples from each hole will be submitted for gold and multi-element analysis.

The 2024 drilling program is being conducted with partner Novamera Inc. and will include Novamera's proprietary Guidance Technology, providing increased data and resource knowledge to define the shape, geometry and continuity of the vein. The drilling is being conducted in the area of a planned bulk sample, which is also fully funded.

The 2024 diamond drilling and subsequent planned bulk sample work at the JMZ is being funded 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 Link to the announcement can be found here.

The planned approximately 2700 tonne bulk sample at the JMZ is to be extracted after diamond drilling and bulk sampling approval using a precision mining method, powered by Novamera's proprietary Surgical Mining technologies. The transformative new mining method leverages hardware, software, AI and ML paired with conventional drilling equipment to extract ore at a fraction of the cost of conventional mining methods.

Great Atlantic confirmed high-grade gold in quartz veins in the west region of the JMZ during 2019 and 2021 diamond drilling programs, including near surface high grade intercepts (core length) of 113.07 grams / tonne (g/t) gold over 0.55 meters and 61.35 g/t gold over 2.04 meters (see Company news releases for results of 2019 and 2021 diamond drilling programs).

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 ounces of gold - uncapped) (see Company News Release of December 6, 2018; and Sedar-filed National Instrument 43-101 Technical Report on the Golden Promise Property, Central Newfoundland (revised), dated December 4, 2018 by Mr. Greg Z. Mosher, M.Sc. App., P.Geo., and Mr. Larry Pilgrim, B.Sc., P.Geo.).
