Great Atlantic Begins 2021 Exploration Program at Its 100% Owned - Golden Promise Gold Property - Central Newfoundland

VANCOUVER, May 27, 2021 - Great Atlantic Resources Corp. (TSXV:GR) (the "Company" or "Great Atlantic") is pleased to announce it has begun the 2021 exploration program at its Golden Promise Gold Property, located in the central Newfoundland gold belt. Exploration is underway in the northern region of the property to define trenching and drilling targets. Two rock samples collected by the Company during 2017 from quartz float in this region returned 57.5 and 200 grams / tonne gold (Company News Release of August 28, 2017). This is referred to as the Branden float occurrence.

Great Atlantic is currently conducting prospecting and rock / soil geochemical sampling in the area of the Branden float occurrence. Following this work, the Company will continue the 2021 exploration program on multiple target areas throughout the property. Planned work consists of prospecting, rock / soil geochemical sampling, geophysical surveys, trenching and diamond drilling. The Company is preparing trenching and diamond drilling permit applications for priority areas including the Jaclyn Zone, the Otter Brook gold showing and a zone of gold soil geochemical anomalies within the southwest region of the property (referred to as Soil Anomaly No. 1).

The Golden Promise Property hosts gold bearing quartz veins in various regions of the property including the Jaclyn Zone, Shawn's Shot vein, Otter Brook showing, Linda / Snow White quartz vein system and the Gabbro occurrence. Great Atlantic confirmed high-grade gold at the Jaclyn Main Zone during 2019 drilling, including core length intercepts of 113.07 grams / tonne (g/t) gold over 0.55 meters and 61.35 g/t gold over 2.04 meters. The Company confirmed gold mineralization at the Otter Brook showing during 2020 including an outcrop grab sample returning 5.75 g/t gold. In addition to the high-grade float at the Branden float occurrence Great Atlantic has confirmed high grade quartz vein float at the Jaclyn North Subzone (including samples returning 157.5, 163.9, 208.5 and 332.6 g/t gold). Please see the Company's website for news releases reporting previous work.

The Golden Promise Property is located within a region of recent significant gold discoveries. The property is located within the Exploits Subzone of the Newfoundland Dunnage Zone. Within the Exploits Subzone, the property lies along the north-northwestern fringe of the Victoria Lake Supergroup (VLSG), a volcano-sedimentary terrane. The northwestern margin of the Golden Promise Property occurs proximal to, and, in part, contiguous with a major (Appalachian-scale) collisional boundary, and suture zone, known as the RIL. The RIL forms the western boundary of the Exploits Subzone. Recent significant gold discoveries within the Exploits Subzone include those of Marathon Gold Corp. (TSX.MOZ) at the Valentine Gold Project, Sokoman Minerals Corp. (TSXV.SIC) at the Moosehead Gold Project and New Found Gold Corp. (TSXV.NFG) at the Queensway Project. Readers are warned that mineralization at the Valentine Gold Project, Moosehead Gold Project, and Queensway Project is not necessarily indicative of mineralization on the Golden Promise Property.

Great Atlantic reported a National Instrument 43-101 mineral resource estimate for the Jaclyn Main Zone (JMZ) in late 2018 (Company News Release of December 6, 2018; and Sedar-filed National Instrument 43-101 Technical Report on the Golden Promise Property, Central Newfoundland (revised), dated December 4, 2018 by Mr. Greg Z. Mosher, M.Sc. App., P.Geo., and Mr. Larry Pilgrim, B.Sc., P.Geo.). The reported inferred mineral resource estimate for the JMZ is as follows:

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves.
Mineral resource tonnage and contained metal have been rounded to reflect the accuracy of the estimate, and numbers may not add due to rounding.
Mineral resource tonnage and grades are reported as undiluted.
Contained Au ounces are in-situ and do not include recovery losses.

As reported in the National Instrument 43-101 Technical Report on the Golden Promise Property, Central Newfoundland (revised), dated December 4, 2018 by Mr. Greg Z. Mosher, M.Sc. App., P.Geo., and Mr. Larry Pilgrim, B.Sc., P.Geo., the JMZ was modelled as a single quartz vein that strikes east-west and dips steeply to the south. Modelled vein thickness was based on true thickness derived from quartz vein intercepts. The estimate is based on 220 assays that were composited to 135 one-meter long composites. A bulk density of 2.7 g/cm³ was used. Blocks in the model measured 15 meters east-west, 1-meter north-south and 10 meters vertically. The block model was not rotated. Grades were interpolated using inverse-distance squared (ID²) weighting and a search ellipse that measured 100 meters along strike, two meters across strike and 50 meters vertically. Grades were interpolated based on a minimum of two and a maximum of 10 composites with a maximum of one composite per hole so the grade of each block is based on at least two drill holes thereby demonstrating continuity of mineralization. For the capped mineral resource estimate, all assays that exceed 65 g/t gold were capped at 65 g/t gold. All resources were classified as Inferred because of the relatively wide spacing of drill holes through most of the zone.

Because part of the vein is near surface the resource estimate was constrained by a conceptual open pit to demonstrate reasonable prospects of eventual economic extraction. Generic mining costs of US$2.50/tonne and processing costs of US$25.00/tonne were used together with a gold price of US$1,300/ounce. A conceptual pit slope of 45° was assumed with no allowance for mining loss or dilution. Based on the combined hypothetical mining and processing costs and the assumed price of gold, a pit-constrained cutoff grade of 0.6 g/t was adopted. For the underground portion of the resource a cutoff of 1.5 g/t was assumed. The cutoff grade for the total resource is the weighted average of the pit-constrained and underground cutoff grades.
