CEO.CA Chairman's Briefing

Vancouver, British Columbia--(Newsfile Corp. - November 19, 2024) - GREAT ATLANTIC RESOURCES CORP. (TSXV: GR) (FSE: PH02) (the "Company" or "Great Atlantic") is pleased to announce its wholly owned subsidiary, Golden Promise Mines Inc., has received gold analyses for the first two holes of the 2024 diamond drilling program at its Golden Promise Gold Property, located in central Newfoundland. The holes were drilled at the gold-bearing Jaclyn Main Zone.

Drill hole GP-24-157 intersected 34.87 grams / tonne (g/t) gold over 0.53 meters while GP-24-158 intersected 12.96 g/t gold over 0.64 meters. These intervals are core length. These half core samples were collected from quartz veins containing visible gold.

Drill holes GP-24-157 and GP-24-158 were the first two holes completed during the 2024 fully funded drill program at the gold-bearing Jaclyn Main Zone (JMZ). Eight holes have ben completed to date during 2024 at the JMZ totalling 716.5 total meters. The 2024 drilling was conducted in the west region of the JMZ in the area of a planned bulk sample. The eight 2024 holes 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.

Drill 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 to a length of 68 meters. Drill hole GP-24-158 was drilled slightly northwest (approximately 346 degrees) at a dip of approximately 61 degrees to a length of 80.5 meters. Each hole intersected a quartz vein with visible gold, interpreted by Great Atlantic management to be the main JMZ vein / vein system. Two sawed half core samples from these veins were submitted to Eastern Analytical Ltd. for gold and multi-element analysis. The samples and gold analytical results include the following (core length):

• GP-24-157 (sample E534851): 34.47 - 35.00 meters (0.53 meters): 34.879 g/t gold

• GP-24-158 (sample E534852): 45.35 - 45.99 meters (0.64 meters): 12.968 g/t gold

The drill core samples from GP-24-157 and GP-24-58 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 GP-24-157 and GP-24-158 core samples 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 submission 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 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.
