GREAT ATLANTIC RESOURCES 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 southwestern New Brunswick tin-tungsten project. The work is being focused within the southwestern region of the claim within and adjacent to an area of reported tungsten-bearing glacial float, including reported high-grade tungsten.

"Great Atlantic comes with a history of tungsten experience. Both Dave Martin, the VP, and myself were instrumental in bringing the Sisson Brook tungsten-moly project at Northcliff to prefeasibility, which is now moving towards production. Previously, we created a show called Talking Tungsten that highlighted the attributes of tungsten to the general public. Over the past decade, Dave and I have assembled a high-quality package of tungsten assets in New Brunswick and Newfoundland. We own 100 per cent of these assets under Great Atlantic and are now seeking partners to advance the projects while we focus our primary efforts on developing the Golden Promise mine," stated Christopher Anderson, chief executive officer of Great Atlantic.

The Flume Ridge mineral claim is one of seven mineral claims located in southwestern New Brunswick, the claims comprising the company's 100-per-cent-owned southwestern New Brunswick tin-tungsten project. These mineral claims were acquired by Great Atlantic through a purchase agreement (see company news release of March 7, 2025).

The Flume Ridge claim hosts the Flume Ridge tungsten mineral occurrence with scheelite reported in quartz veins (New Brunswick Department of Natural Resources and Energy Development, mineral occurrence database, reference No. 1448).

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 per cent tungsten (0.76 per cent WO3) over 0.57 metre (core length) and 0.557 per cent tungsten (0.70 per cent WO3) over 0.65 metre (core length) (Martin, 2010; report of work No. 476928). Four 2009 trenches -- stripped areas --were reported to expose tungsten (scheelite)-bearing quartz veins (Martin, 2010, report of work No. 476928). A bedrock grab sample reported during 2018 from one of these trenches was reported to return 1.58 per cent tungsten (1.99 per cent WO3) (Steven, 2018, report of work No. 478371).

The 2026 work is being focused within the southwestern 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 parts per million (greater than 0.30 per cent W) including two samples reported to return 13,000 ppm tungsten (1.30 per cent W or 1.64 per cent WO3) and 16,600 ppm tungsten (1.66 per cent W or 2.09 per cent WO3) (Stevens, 2021, report of work No. 479103).

Readers are warned that Great Atlantic has not verified historically reported tungsten analytical results for the area of the Flume Ridge claim.
