VANCOUVER, BC / ACCESSWIRE / September 10, 2024 / Grande Portage Resources Ltd. (TSXV:GPG)(OTCQB:GPTRF)(FSE:GPB) (“Grande Portage” or the “Company”) is pleased to announce that it has signed a Letter of Intent (“LOI”) with Goldbelt, Incorporated (“Goldbelt”) to explore the potential development of an ore terminal at Goldbelt’s Cascade Point site in Southeast Alaska, approximately 53 km northwest of the City of Juneau.

As previously announced on September 9^and 2024, the Company’s Conceptual Mining Plan evaluates the development of the New Amalga gold mine as a selective underground mining operation that would extract high-grade material with minimal dilution. Due to the project’s location near tidal waters and less than 4 miles (6.5 km) from existing paved highway, the Company considers off-site processing to be the most favorable configuration and is exploring numerous business opportunities including strategic partnerships, potential use of third-party facilities around the Pacific Rim and direct shipping to smelters in East Asia.
