Great Atlantic Resources Corp. announced it has completed its 2023 program of prospecting and rock geochemical sampling at its Mascarene Property, located in southwest New Brunswick. The highlight of the program was the discovery of sulfide-bearing quartz veins in one area in the north-central region of the property.

Rock samples have been collected and submitted for gold and multi-element analysis of which the analytical results are pending. The 2023 prospecting and rock geochemical samples was conducted in the west and north-central regions of the Mascarene Property. The work in the north-central region was conducted southeast of the reported location of the Mascarene Gold mineral occurrence (New Brunswick Department of Natural Resources and Energy Development Mineral Occurrence Database - Reference No.

1323). Great Atlantic has not confirmed this mineral occurrence. During the 2023 work, Great Atlantic located sulfide bearing quartz veins in outcrops at three locations within an area of approximately 200 meters by 50 meters.

The quartz veins vary from approximately 0.2 meters to 1.3 meters wide and contain pyrite and /or chalcopyrite. Seven outcrop grab samples were collected from these quartz veins. Two other samples was collected in this area from quartz vein subcrop and from a glacially transported float with quartz veins.

These nine samples have been submitted to ALS Canada Ltd. for gold and multi- element analysis. The work in the west region of the property was conducted south-southwest of historic workings interpreted by Great Atlantic management to be associated with the reported Simpson Prospects mineral occurrence. Six rock samples were collected in this region, six being grab samples from outcrop and one sample collected from glacially tranported float.

These include quartz vein samples with +/- pyrite and mafic volcanic samples with+/- pyrite and pyrrhotite, one of which is cut by a shear /fault zone. These six rock samples have been submitted to ALSCanada Ltd. for gold and multiple-element analysis. Great Atlantic previously confirmed high-grade zinc mineralization in rubble at the Simpson Prospects workings with two 2018 rubble samples yielding 12.6% zinc and 12.3% zinc. A broad northeast trending zone of magnetic high anomalies (identified during a 2001 government airborne magnetic survey) transects the entire Mascarene Property.

Great Atlantic's management speculate this magnetic high trend to be associated with a buried mafic intrusion (s) and a possible target for mafic intrusive hosted copper-nickel-cobalt deposits.
