GREAT ATLANTIC COMMENCES 2026 EXPLORATION PROGRAM AT ITS GLENELG GOLD - ANTIMONY - VANADIUM PROPERTY, SOUTHWEST NEW BRUNSWICK

Great Atlantic Resources Corp. is commencing the 2026 exploration program at its Glenelg gold-antimony-vanadium property, located in southwestern New Brunswick.

The 2026 exploration program will focus on specific targets areas within the property in which the company had previously collected rock samples containing gold, antimony, vanadium, lithium and titanium mineralization (including high-grade antimony at one location).

"We are very encouraged by the combination of gold and high-grade antimony discovered at Glenelg, particularly given the strong global demand for critical metals. Our 2026 program will focus on rapidly advancing these discoveries toward drill targets while expanding exploration across multiple mineralized zones on the property. We believe Glenelg has the potential to emerge as an important polymetallic discovery in Atlantic Canada," states Christopher Anderson, chief executive officer.

Great Atlantic is planning work during 2026 in three target areas within the Glenelg property to further define sites for trenching and/or diamond drilling. A combination of focused prospecting, rock/soil geochemical sampling and geophysical surveys is planned within the three target areas. These target areas are as follows.

South-central region: This is a large target area approximately two kilometres by two kilometres in size, containing three gold (plus or minus silver, copper) occurrences (as per the New Brunswick Department of Natural Resources and Energy Development, mineral occurrence database files), a new gold discovery (2025 discovery) and a vein containing high grade antimony (2022 discovery).

At the Johnson Lake gold-silver occurrence, Great Atlantic located a gold-bearing outcrop during 2023. Rock samples collected by the company during 2023 to 2025 at this outcrop yielded highly anomalous gold values of 0.50 gram per tonne (g/t), 0.46 g/t and 0.73 g/t (see the company's news releases of Nov. 30, 2023, March 24, 2025, and Feb. 18, 2026). This outcrop is altered and pyrite bearing.

Great Atlantic discovered an antimony-bearing vein (quartz-carbonate-stibnite) during 2022 within the southern region of this target area. The vein occurs in a highway-cut bedrock exposure. This vein contains high-grade antimony locally (massive stibnite occurs locally in the vein at the bedrock exposure). This northwest-striking and steeply dipping vein was sampled during 2022 and 2023 (vein is up to 0.6 metre (m) wide where sampled). Five samples from the vein returned antimony values of (see the company's news releases of Aug. 16, 2022, and April 30, 2024):

• 23.4 per cent antimony (Sb) (2022 grab sample weighing 1.83 kilograms);
• 13.75 per cent Sb (2023 grab sample weighing 6.36 kilograms);
• 13.70 per cent Sb (2023 grab sample weighing 4.94 kilograms);
• 2.98 per cent Sb (2023 grab sample weighing 6.34 kilograms);
• 0.36 per cent Sb (2023 grab sample weighing 6.81 kilograms).

During 2025, Great Atlantic discovered gold mineralization within a fault zone approximately 55 metres southwest of the antimony-bearing vein along the same roadside bedrock exposure. A 2025 grab sample from this fault zone returned a highly anomalous gold value of 1.72 g/t while also returning anomalous values for silver (5.9 g/t), bismuth (3,290 parts per million (ppm)), cobalt (691 ppm) and copper (635 ppm) (see the company's news release of Feb. 18, 2026).

Grid-level soil geochemical sampling, additional prospecting and rock geochemical sampling, and geological mapping and geophysical surveys are planned during 2026 in this target area, being focused in the areas of the three reported mineral occurrences and the southernmost part of this target area in the area of the antimony-bearing vein and the gold-bearing fault zone discovered during 2025. Given that the company has already confirmed gold and antimony mineralization in bedrock in this area, company management interpret some general sites for trenching and/or diamond drilling have already been identified in this area. The objective of the planned work is to further define these sites and evaluate other potential sites such as at the Chris Wrem Lake North and Chris Wren Lake South occurrences.

North-central region: Great Atlantic collected rock samples from glacial float and outcrop exposures in this area during 2023 to 2024 containing anomalous levels for gold and/or lithium. Samples collected during 2023 from this target area included an outcrop grab sample from a highly oxidized and locally faulted outcrop, which returned an anomalous value of 820 ppm lithium, and a sample from a granite boulder with quartz veins, which returned an anomalous value of 920 ppm lithium (see the company news release of March 14, 2024). Two rock samples collected during 2024 in this area returned anomalous gold values of 0.159 g/t (outcrop) and 0.104 g/t (subcrop), establishing gold potential in this area.

Grid-level soil geochemical sampling, as well as additional prospecting and rock geochemical sampling, are planned during 2026 in this target area to better define the target area. Geophysical surveys (magnetic and electromagnetic) are planned following this work with the combined results being evaluated to determine potential trenching and/or diamond drilling sites.

Southeast region: Great Atlantic confirmed vanadium mineralization during 2018 at one location within the southeast region of the Glenelg property within the Bocabec Gabbro complex. A 2018 outcrop grab sample from this region returned 0.33 per cent V2O5 (see the company's news release of May 6, 2019). Focused prospecting and rock sampling are planned during 2026 in this area of the property with a focus on vanadium exploration.

Gold analysis of the 2023-2025 rock samples discussed in this news release was by fire assay-AA (atomic absorption) while antimony analysis of 2022 and 2023 rock samples discussed in this news release was by XRF (X-ray fluorescence) (following lithium borate fusion). The 2023 rock samples yielding anomalous lithium values were analyzed by four-acid digestion -- ICP-AES (inductively coupled plasma atomic emission spectroscopy) analysis. Vanadium analysis of the 2018 rock sample discussed in this news release was by XRF fusion. ALS Canada Ltd., a certified laboratory independent of Great Atlantic, conducted the analysis of these rock samples.

The 2018-2025 exploration programs at the Glenelg property were supervised by a qualified person.

Part of the northern boundary of the Glenelg property borders the Clarence Stream project of Galway Metals Inc. Galway reported a National Instrument 43-101 resource estimate for the project during 2022, reporting total indicated resources of 12,396,000 tonnes at 2.31 g/t gold (contained indicated 922,000 ounces of gold and 9,605 tonnes of antimony) and total inferred resources of 15,963,000 tonnes at 2.60 g/t gold (contained inferred 1,334,000 ounces of gold and 2,145 tonnes of antimony). Readers are warned that mineralization at the Clarence Stream project is not necessarily indicative of mineralization within the Glenelg property.

David Martin, PGeo (New Brunswick and Newfoundland and Labrador), a qualified person as defined by National Instrument 43-101 and vice-president of exploration for Great Atlantic, is responsible for the technical information contained in this news release.
