Great Atlantic Resources Corp. (TSXV: GR) announced that its wholly-owned subsidiary, Golden Promise Mines Inc., has received rock sample analyses confirming a new gold and copper mineralized zone at the 100%-owned Golden Promise Property in central Newfoundland. The zone, initially discovered during a 2024 trenching program, returned gold values as high as 1.008 grams per tonne (g/t) Au from 2025 bedrock grab samples. The results reinforce the property's potential within the Exploits Subzone of the Newfoundland Dunnage Zone, a recognised gold belt in Atlantic Canada.

Key Points

  • Great Atlantic Resources Corp. (TSXV: GR) — Canadian mineral exploration company focused on Atlantic Canada
  • Golden Promise Mines confirmed gold-copper mineralization in bedrock at the southwest region of the Golden Promise Property through 2025 rock sampling
  • Three 2025 bedrock grab samples returned 1.008 g/t Au, 0.807 g/t Au with copper exceeding the 10,000 ppm upper analytical limit, and 0.443 g/t Au respectively
  • Golden Promise Mines plans geophysical surveys and additional trenching within the mineralized zone area

2025 Sampling Confirms Gold-Copper Bedrock Mineralization at Golden Promise Southwest Zone

Three bedrock grab samples collected in 2025 along an approximately 4-metre section of the zone returned values of 1.008 g/t Au with 155 ppm copper, 0.807 g/t Au with copper exceeding the 10,000 ppm upper analytical limit and silver exceeding 6 ppm, and 0.443 g/t Au with 680 ppm copper. A fourth 2025 sample taken from subcrop atop the same bedrock exposure returned 0.370 g/t Au. These results follow the initial 2024 grab sample, which returned 0.481 g/t Au along with copper exceeding 10,000 ppm and silver exceeding 6 ppm. All samples were analysed by Eastern Analytical Ltd., an independent certified laboratory.

Structural Characteristics of the Mineralised Zone Identified Through Trenching

The 2024 excavator trenching program exposed a narrow sulphide-bearing zone containing pyrite and chalcopyrite, with quartz veining, silicification, and shearing in bedrock. The zone measures up to 0.4 metres wide at the bedrock exposure, trends northeast-southwest, and is subvertical in orientation. The trench was subsequently backfilled, though the bedrock exposure containing the gold and copper mineralisation extends to surface and was left exposed. The release states that the zone has not yet been traced along its projected strike, leaving its full lateral extent undetermined at this stage of exploration.

Golden Promise Property Context Within Central Newfoundland's Gold Belt

The Golden Promise Property is described as the largest and most advanced of seven central Newfoundland gold properties owned by Golden Promise Mines. It hosts multiple gold-bearing quartz vein systems across various regions, including the Jaclyn Zone, Shawn's Shot, Otter Brook, Linda/Snow White, and Gabbro Zone occurrences. The property is located approximately 50 kilometres northeast of the Valentine Gold Mine operated by Equinox Gold Corp. (TSX: EQX, NYSE: EQX), also within the Exploits Subzone. The company cautions that mineralisation at Valentine is not necessarily indicative of results at Golden Promise or any other Golden Promise Mines property.
