GREAT ATLANTIC RESOURCES REPORTS GEOPHYSICAL RESULTS MOUNT RAYMOND PROPERTY

Great Atlantic Resources Corp. has provided an update regarding exploration progress at the company's Mount Raymond property, north-central New Brunswick, where Slam Exploration Ltd. holds an option to earn a 100-per-cent interest in the project through a combination of common share issuances and incurrence of exploration expenditures on the property. See Great Atlantic's March 4, 2026, news release for details. Slam Exploration completed a VTEM-Plus airborne electromagnetic geophysical survey during early 2026 at its Goodwin copper-nickel-cobalt project. This survey covered much of Great Atlantic's Mount Raymond property (mineral claim No. 8569).

As announced in its June 1, 2026, new release, Slam Exploration "is using the new VTEM survey over the Goodwin copper-nickel-cobalt project to generate targets and to plan the 2026 diamond drilling program," and "from a total of 432 anomalies," Slam Exploration "has constructed plate models for 24 conductors that range in depth from 30 metres to 320 metres." Slam Exploration states, "All of these models are potential extensions to the known zones of mineralization and could represent ovoid-type deposits with higher-grade mineralization at depth."

"We are pleased to see further exploration work begin in this mineral-rich province as Slam Exploration prepares for their upcoming diamond drilling program," stated Christopher Anderson, chief executive officer of Great Atlantic. "We believe the project adds to the significant exploration potential of the region as the demand for critical and strategic minerals increases."

Twenty-one VTEM electromagnetic conductors reported by Slam Exploration are within or along the boundaries of Great Atlantic's Mount Raymond property. Most of these conductors are within two target areas identified by Slam Exploration (target T07 and target T08).

The Mount Raymond property was acquired by Great Atlantic during 2018 by staking. The property covers an area of approximately 175 hectares. The property covers a reported cobalt-copper-nickel mineral occurrence (New Brunswick Department of Natural Resources and Energy Development, Mineral Occurrence Database, reference No. 1529). Drill core samples anomalous for vanadium are also reported (Gracia, 2012).

A 2011 diamond drill hole (VM-11-16) reported within the area of the Mount Raymond property was reported to intersect 1.65 metres of semi-massive sulphides (pyrrhotite) with chalcopyrite veinlets within gabbro (Gracia, 2012). This mineralized interval was reported to return 0.43 per cent copper, 0.12 per cent nickel and 0.11 per cent cobalt over 1.65 metres (core length). Another one-metre core length sample from this hole was reported to return 0.18 per cent cobalt while another one-metre core length sample from this hole was reported to return 0.12 per cent vanadium (Gracia, 2012). These mineralized intervals are reported near surface (within 100-metre vertical depth). A qualified person has not verified this mineralization for Great Atlantic.

David Martin, PGeo (New Brunswick and Newfoundland and Labrador), a qualified person as defined by National Instrument 43-101 and vice-president, exploration, for Great Atlantic, reviewed and approved the technical information contained in this news release. Great Atlantic has not verified the VTEM electromagnetic anomalies stated in this news release.
