Great Atlantic Resources Corp. Begins 2026 Exploration Program At Flume Ridge Claim of 100% Owned Southwest New Brunswick Tin-Tungsten Project Great Atlantic Resources Corp. has commenced a focused prospecting and rock geochemical sampling program at the Flume Ridge mineral claim, being part of its Southwest New Brunswick Tin-Tungsten Project. The work is being focused within the southwest region of the claim within and adjacent to an area of reported tungsten bearing glacial float including reported high-grade tungsten. The Flume Ridge mineral claim is one of seven mineral claims located in southwest New Brunswick, the claims comprising the Company's 100% owned Southwest New Brunswick Tin - Tungsten Project. These mineral claims were acquired by Great Atlantic through a purchase agreement. The Flume Ridge claim hosts the Flume Ridge Tungsten mineral occurrence with scheelite reported in quartz veins. Reports of Work on file with the New Brunswick Department of Natural Resources and Energy Development document previous exploration within the Flume Ridge claim. Two 2009 drill holes within the southern region of the claim were reported to intersect 0.608% tungsten (0.76% WO3) (WO3= W * 1.26) over 0.57 meters (core length) and 0.557% tungsten (0.70% WO3) over 0.65 meters core length. Four 2009 trenches - stripped areas were reported to expose tungsten (scheelite) bearing quartz veins. A bedrock grab sample reported during 2018 from one of these trenches was reported to return 1.58% tungsten (1.99% WO3). The 2026 work is being focused within the southwest region of the claim including an area of reported tungsten bearing glacial float. At least 16 rock samples collected during 2020 by the late Dave Stevens of Campfire Resources Ltd. from glacial float in this region of the claim were reported to return tungsten values greater than 3,000 ppm (>0.30% W) including two samples reported to return 13,000 ppm tungsten (1.30% W or 1.64% WO3) and 16,600 ppm tungsten (1.66% W or 2.09% WO3).

Great Atlantic Resources Corp. Provides Update on Diamond Drilling At Pilley's Island Project Great Atlantic Resources Corp. provided an update on diamond drilling by HM Exploration Corp. at Great Atlantic's Pilley's Island Project at Pilley's Island, north-central Newfoundland. HM Exploration holds an option to earn a 100% interest in the project. HM Exploration has provided an update for the ninth to twelfth drill holes (PI-26-009 to PI-26-012) completed this year at the project. The four holes were all drilled within the area of Great Atlantic's Pilley's Island Project. Drill holes PI-26-009 to PI-26-012 discussed in this news release represent an additional 1,115.60 metres for a total drilled meterage of 2,747.87 metres. Holes nine and ten have successfully intersected the new blind discovery of massive sulphide mineralization extending the strike length of the lower-zone to approximately 40m northwest. The upper-zone mineralized trend can be traced consistently over approximately 130m northwest. The mineralization observed in the lower-lens of holes nine and ten displays similar characteristics as PI-26-008. Multiple mineralized intervals were encountered displaying varying types of mineralization ranging from disseminated – semi-massive – massive sulphide, including: PI-26-009 from 17.00 – 22.45m down-hole; 5.45m drilled length. From 155.03 – 157.66m down-hole; 2.63m drilled length. PI-26-010 from 141.81 – 145.90m down-hole; 4.09m drilled length. Abundant angular copper-bearing clasts observed, potentially indicating limited transport from the source and proximity to a hydrothermal vent environment. Planning is underway for a downhole electromagnetic (EM) survey, followed by a Phase Two diamond drilling program designed to further test the expanding mineralized system. Assay results for the Phase One drilling program are expected to be released shortly. HM Exploration states the 2026 Phase One Drilling program was focused on evaluating the continuity of the mineralized system below known surface showings and along strike of the Clifford Jones Zone to improve their understanding of the geological controls on mineralization. Visual observations from drilled holes indicate that the upper targeted copper-bearing debris flow was successfully intersected, with zones of alteration and massive to semi-massive sulphide mineralization observed in the drill core. HM Exploration states that drill holes 9 and 10 have successfully intersected a lower mineralized sulphide lens that was previously undiscovered. Core samples have been submitted to the laboratory for analysis. Assay results will be released once they have been returned to HM Exploration. HM Exploration states the holes intersected a wide range of massive, semi-massive and disseminated sulphide mineralization over the following drill core lengths: PI-26-009 from 17.00 – 22.45m down-hole; 5.45m drilled length. From 155.03 – 157.66m down-hole; 2.63m drilled length. PI-26-010 from 141.81 – 145.90m down-hole; 4.09m drilled length. PI-26-011 from 143.57 – 144.94m down-hole; 1.37m drilled length. PI-26-012 from 22.32 – 23.15m down-hole; 0.83m drilled length. HM Exploration states observations from drill core continue to support the interpretation that the new lower mineralized sulphide lens may represent debris deposited closer to the original hydrothermal vent system. HM Exploration states that mineralization can be described as clast-dominated debris zones predominantly consisting of sub-angular to angular fragments of massive sulphide composed of Cpy + Py ± Sph ± Gn suspended in interstitial fine-grained disseminated sulphides (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. Matrix-dominated debris flow composed of fragments of sub-rounded to angular clasts of massive sulphide (Py + Cpy ± Sph ± Gn) and felsic ± mafic lithic fragments suspended in a matrix of fine-grained sulphide (Py + Cpy ± Sph ± Gn) and milled felsic ± mafic rock. More detailed classifications for individual intercepts are referenced in Table 2. HM Exploration and Great Atlantic caution that the presence of visible sulphides and visual estimates of mineral abundance are not indicative of grade and should not be considered a substitute for laboratory analysis. Assay results are pending. True widths of mineralized intersections are currently unknown. HM Exploration states the 2026 drill collar data; Coordinates reported in NAD83 - Zone 21N. HM Exploration states mineralized interval descriptions. HM Exploration states the Project is located within the Notre Dame Subzone of the Dunnage Tectonostratigraphic Zone. Most of the Project is underlain by Ordovician submarine volcanic rocks of the Roberts Arm Group which is regionally identified as part of a mature arc sequence referred to as the Buchans-Roberts Arm Belt that also hosts the historic Buchans mine. Mineralization occurs as lower grade (Spencer's Dock); medium grade (Old Mines); and high grade (3B-Zone/Clifford Jones) deposits that are of both sub-seafloor replacement and exhalative varieties. The deposits are often flanked by extensive chlorite, sericite, silica, K-feldspar and epidote alteration often observed in bimodal-felsic VMS systems. The Spencer's Dock area displays sericite/silica alteration that generally increases in intensity near mineralized zones, while the 3B/Old Mine areas display sericite/silica alteration that is abundant but less widespread and is more intense when proximal to mineralized zones. VMS deposits are a globally significant source of copper, zinc, lead, silver, and gold. The Project's geology shares key characteristics with known Volcanogenic Massive Sulphide districts in Newfoundland, including the past producing Buchans, Ming and Rambler Mines, supporting the exploration potential of the Project.

New major risk - Share price stability The company's share price has been highly volatile over the past 3 months. It is more volatile than 90% of Canadian stocks, typically moving 18% a week. This is considered a major risk. Share price volatility increases the risk of potential losses in the short-term as the stock tends to have larger drops in price more frequently than other stocks. It may also indicate the stock is highly sensitive to market conditions or economic conditions rather than being sensitive to its own business performance, which may also be inconsistent. Currently, the following risks have been identified for the company: Major Risks Less than 1 year of cash runway based on free cash flow trend (-CA$1.6m free cash flow). Share price has been highly volatile over the past 3 months (18% average weekly change). Negative equity (-CA$5.8m). Revenue is less than US$1m. Market cap is less than US$10m (CA$4.98m market cap, or US$3.57m). Minor Risk Shareholders have been diluted in the past year (16% increase in shares outstanding).
