Great Atlantic Resources Corp. 5th Drill Hole Intersects Two Veins:

The fifth hole of the 2024 program (GP-24-161) 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-24-161 intersected 120.89 grams / tonne (g/t) gold over 0.44 meters and 13.16 g/t gold over 1.67 meters (including 10.92 g/t gold over 1.04 meters and 16.87 g/t gold over 0.63 meters). These intervals are core length. These half core samples were collected from two quartz vein intervals containing visible gold.

GP-24-161 was the fifth of eight cross cutting drill holes (716.5 total meters) at the JMZ completed during September October of 2024, the program being fully funded. These holes were drilled in the west region of the JMZ within the planned (2025) bulk sample area. All eight holes were drilled on the same northwest - southeast trend to intersect the steeply dipping, east to slightly northeast trending JMZ. The eight holes were designed to target the JMZ between surface and approximately 100 meters vertical depth.

Drill hole GP-24-161 was collared at the same site as hole GP-24-160. GP-24-161 was drilled slightly northwest (approximately 346 degrees) at a dip of approximately 60 degrees and to a length of 128 meters. The hole intersected two quartz veins with visible gold, the first vein intersected being brecciated and containing a mafic dyke. Three sawed half core samples from these vein intervals (one from the first vein and two samples from the second vein) were submitted to Eastern Analytical Ltd. for gold and multi-element analysis. The samples and gold analytical results are as follows (core length):

• Sample E534857: 82.56 - 83.00 meters (0.44 meters): 120.890 g/t gold
• Sample E534858: 91.80 - 92.84 meters (1.04 meters): 10.922 g/t gold
• Sample E534859: 92.84 - 93.47 meters (0.63 meters): 16.875 g/t gold

Great Atlantic previously announced results of drill core samples from drill holes GP-24-157, GP-24-158 and GP-24-160, the first, second and fourth holes of the 2024 diamond drilling program at the JMZ (see Company news releases of November 19^th and December 4^th, 2024). These included core samples from quartz vein intervals with visible gold with intercepts including (core length):

• GP-24-157: 34.47 - 35.00 meters (0.53 meters): 34.879 g/t gold
• GP-24-158: 45.35 - 45.99 meters (0.64 meters): 12.968 g/t gold
• GP-24-160: 52.19 - 52.43 meters (0.24 meters): 14.769 g/t gold
• GP-24-160: 78.95 - 79.52 meters (0.57 meters): 19.121 g/t gold

The drill core samples from GP-24-157, GP-24-158, GP-24-160 and GP-24-161 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 assay - 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, GP-24-160 and GP-24-161 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.

The 2024 drilling was conducted with partner Novamera Inc. Two additional close-spaced drill holes (9^th and 10^th 2024 drill holes) were completed during December of 2024 in this area of the JMZ. The 9^th and 10^th 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. These two steep holes were drilled approximately down - dip of the JMZ and are located in the area of the planned 2025 bulk sample, which is also fully funded. 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. A third down-dip hole is planned at this site in early 2025.

The 2024 diamond drilling and subsequent planned bulk sample work at the JMZ was / 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 in 2025 after diamond drilling and bulk sampling approval using a precision mining method, powered by Novamera's full suite of Surgical Mining^TM 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.).

The Golden Promise Property is the largest and most advanced of seven central Newfoundland gold properties owned by Golden Promise Mines Inc. and located within the Exploits Subzone of the Newfoundland Dunnage Zone. One of these properties (Golden Trust) is located within one kilometer of the Valentine Gold Mine of Calibre Mining Corp. (TSX: CXB) (OTCQX: CXBMF) 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 Inc.
