Great Atlantic Intersects 19.1 G/T Gold over 0.57 Meters in Fourth 2024 Drill Hole at the Jaclyn Main Zone Planned Bulk Sample Area at its 100% Owned Golden Promise Gold Property

Vancouver, December 4, 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 received gold analyses for the fourth hole of the 2024 diamond drilling program at its Golden Promise Gold Property, located in central Newfoundland. The hole (GP-24-160) was drilled at the gold-bearing Jaclyn Main Zone (JMZ). Golden Promise Mines Inc., along with partner Novamera inc., is planning to extract a bulk sample during 2025 from this area of the JMZ.

GP-24-160 intersected 19.12 grams / tonne (g/t) gold over 0.57 meters and 14.76 g/t gold over 0.24 meters. The intervals are core length. These half core samples were collected from quartz vein intervals containing visible gold.

GP-24-160 was the fourth hole completed during the 2024 fully funded drill program at the JMZ. Eight holes have ben completed to date during 2024 at the JMZ totalling 716.5 total meters. These holes were drilled in the west region of the JMZ within the planned bulk sample area. All were drilled on the same northwest - southeast trend to intersect the steeply dipping, east to slightly northeast trending JMZ. The holes were designed to target the JMZ between surface and approximately 100 meters vertical depth.

GP-24-160 was drilled slightly northwest (approximately 344 degrees) at a dip of approximately 51 degrees and to a length of 98 meters. The hole intersected two quartz veins with visible gold. Two sawed half core samples from these vein intervals were submitted to Eastern Analytical Ltd. for gold and multi-element analysis. The samples and gold analytical results are as follows (core length):

• Sample E534853: 52.19 - 52.43 meters (0.24 meters): 14.769 g/t gold
• Sample E534854: 78.95 - 79.52 meters (0.57 meters): 19.121 g/t gold

Great Atlantic previously announced results of drill core samples from drill holes GP-24-157 and GP-24-158, the first two holes of the 2024 diamond drilling program at the JMZ. These included core samples from quartz vein intervals with visible gold. Drill hole GP-24-157 intersected 34.87 g/t gold over 0.53 meters while GP-24-158 intersected 12.96 g/t gold over 0.64 meters (see the Company website for the news release). These intervals are core length. Analytical results are pending for drill core samples from drill holes GP-24-159 and GP-24-161 to GP-24-164.

The drill core samples from GP-24-157, GP-24-158 and GP-24-160 were analyzed at Eastern Analytical Ltd. The samples were assayed for gold by the Total Pulp Metallics method. This involves crushing of the entire sample to -10mesh and pulverizing to 95% -150mesh. The total sample is then weighed and screened 150mesh. The +150mesh fraction is analyzed for gold by fire assay - atomic absorption (AA), and a 30-gram subsample of the -150mesh fraction is analyzed for gold by fire assays - AA. A calculated weighted average of total gold in the sample is reported as well (the gold values reported in this news release for the core samples from GP-24-157, GP-24-158 and GP-24-160 are calculated weighted average). The samples were also analyzed for 34 elements (200-mg subsamples totally dissolved in four acids and analyzed by ICP-OES). Eastern Analytical, a certified laboratory, is independent of Golden Promise Mines Inc. and Great Atlantic. Blank and standard samples were included with the drill core sample submissions to Eastern Analytical.

Three additional drill holes are planned during 2024 in this area of the JMZ after a pause to confirm exact collar locations. The drilling program is being conducted with partner Novamera Inc. The three remaining holes of the program will include Novamera's proprietary Guidance Technology, providing increased data and resource knowledge to define the shape, geometry and continuity of the vein. The drill holes are in the area of the 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 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.).
