Great Atlantic Invites Diamond Drilling Proposals for

2024 Fully Funded Jaclyn Main Zone Drilling

at its 100% Owned Golden Promise Gold Property

Central Newfoundland

FOCUSED ON EXPLORING ATLANTIC CANADA

VANCOUVER, British Columbia June 25, 2024 - GREAT ATLANTIC RESOURCES

CORP. (TSXV.GR) (the “Company” or “Great Atlantic”) is pleased to announce its wholly

owned subsidiary, Golden Promise Mines Inc., has invited diamond drilling proposals from

multiple contractors for planned 2024 drilling at its 100% owned Golden Promise Gold Property,

located in the central Newfoundland. Nine holes are planned for approximately 900 meters.

The fully funded drilling program will be conducted during August – September with partner

Novamera Inc. at the gold- bearing Jaclyn Main Zone (JMZ). The drill program will include

Novamera’s proprietary Guidance Technology, providing increased data and res ource

knowledge to define the shape, geometry and continuity of the vein. The drilling is planned for

the area of a planned 2024-2025 bulk sample, also being fully funded.

The objective of the planned 2024 diamond drilling program is to further define gold bearing

quartz veins in one part of the JMZ in preparation for extraction of the bulk sample. The nine

diamond drill holes are planned within the west region of the JMZ targeting gold bearing veins to

approximately 100 meters vertical depth. Golden Promise Mines Inc. submitted an application in

late May to the Newfoundland and Labrador government for the diamond drilling. Pending

approval, the drilling program is planned to begin during late August.

Great Atlantic confirmed high -grade gold in quartz veins in the west region of the Jaclyn Main

Zone during 2019 and 2021 diamond drilling programs , including near surface high grade

intercepts (core length) of 113.07 grams / tonne ( g/t) gold over 0.55 meters and 61.35 g/t gold

over 2.04 meters (see Company news releases for results of 2019 and 2021 diamond drilling

programs).

The planned approximately 2700 tonne bulk sample at the JMZ is to be extracted after diamond

drilling and bulk sampling approval using a precision mining method, powered by Novamera’s

proprietary Surgical Mining technologies. The transformative new mining method leverages

hardware, software, AI and ML paired with conventional drilling equipment to extract ore at a

fraction of the cost of conventional mining methods.

The 2024 diamond drilling and subsequent bulk sample work at the JMZ is being funded in

part by co-investment from DIGITAL, Canada’s Global Innovation Cluster for digital

technologies, as part of a larger project that aims to support data-driven and digital solutions

within the mining sector. The Link to the announcement can be found here.

Great Atlantic reported a National Instrument 43- 101 compliant inferred resource estimate

during late 2018 for the JMZ of 357,500 tonnes at 10.4 g/t gold (119,900 ounces of gold -

uncapped) (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 Golden Promise Gold Property is the largest and most advanced of eight central

Newfoundland gold properties owned by Golden Promise Mines Inc. and located within the

Exploits Subzone of the Newfoundland Dunnage Zone. One of these properties (Golden Trust) is

located within one kilometer of the Valentine Gold Mine of Calibre Mining Corp. ( TSX: CXB;

OTCQX: CXBMF) which is also located within the Exploits Subzone. Readers are warned that

mineralization at the Valentine Gold Mine is not necessarily indicative of mineralization at the

Golden Promise Property or any of the other central Newfoundland gold properties of Golden

Promise Mines Inc.
