Great Atlantic's Golden Promise completes trenching

Executive Summary

• Great Atlantic Resources’ wholly‑owned subsidiary, Golden Promise Mines Inc., completed a four‑hole trenching program at the Golden Promise gold property in central Newfoundland during June 2025.
• The 2025 trenches were located within previously identified gold soil anomalies (up to 77 ppb Au) and near historic 2024 trench sites that returned notable gold, silver, and copper grades.
• Thirty‑eight rock samples from the new trenches and five additional grab samples from a backfilled 2024 trench have been submitted for laboratory analysis; results are pending.

Key Details

• Program Scope: Four trenches excavated in the southwest region of the Golden Promise property (Mineral Licence 036105M), approximately 4 km NE of the Linda/Snow White quartz‑vein system.
• Historical 2024 Trench Highlights (for context):
• Float sample 309464 – 0.964 g/t Au.
• Subcrop sample 309466 – 0.463 g/t Au, 4,287 ppm Cu (0.428 % Cu).
• Bedrock sample 309469 – 0.481 g/t Au, >6.0 g/t Ag, >10,000 ppm Cu (>1 % Cu).
• 2025 Trench Locations:
• Trench 1 positioned between the two 2024 trenches.
• Trench 2 located WSW of 2024 trench 2.
• Trenches 3 and 4 situated ~200 m and ~160 m SW, respectively, of the second 2025 trench.
• Sampling: 38 samples collected from glacial float boulders, subcrop, and outcrop within the four 2025 trenches; all exhibit quartz veining with pyrite‑dominated sulphide mineralization; chalcopyrite observed in samples from Trench 2.
• Additional Grab Samples: Five rock grab samples taken from the backfilled 2024 trench area; three sourced from a narrow (≈0.4 m) silicified, sheared, sulphide‑bearing zone analogous to historic sample 309469.
• Laboratory Work: All 2025 and additional grab samples have been sent to an independent, certified laboratory for gold and multi‑element analysis; results are pending.
• Technical Review: David Martin, P.Geo., Vice‑President of Exploration (qualified person per NI 43‑101), reviewed and approved the technical information disclosed.

Notable Quotes

“Great Atlantic has assembled a prolific and diverse portfolio of 100‑percent‑owned properties in both NB and NFLD… regional work continues in the gold district, and we are developing additional targets and making new discoveries while advancing the bulk sample at the Jaclyn Main zone, which remains our primary focus.” – Christopher Anderson, CEO
