VANCOUVER, BC / ACCESS Newswire / May 7, 2025 / Grande Portage Resources Ltd. (TSXV:GPG)(OTCQB:GPTRF)(FSE:GPB) ("Grande Portage" or the "Company") is pleased to announce that it has staked 64 new federal claims adjacent to its existing exploration claims at the New Amalga Gold project in Southeast Alaska.
The added claims are intended to accommodate future surface facilities in support of a potential underground mine at the site. Such facilities could include buildings and infrastructure for:
Electrical utilities
Equipment maintenance
Ore sorting
Backfill preparation
Supplies warehousing
Water treatment
Office and administration
Environmental studies and fieldwork are ongoing to determine the ideal layout of the potential surface facilities to ensure protection of fish habitat, maintain integrity of wetlands, and minimize overall ecological footprint.
The potential surface facilities are not planned to include an ore processing plant. Due to the resource location near tidewater and less than 4 miles (6.5km) from existing paved highway (Fig. 1), the Company considers off-site processing by a third party to be the most favorable configuration for the project. This setup provides several potential benefits:
Eliminates the need to build a concentrator, greatly reducing project construction CAPEX
Results in no tailings generated at the site, removing the need to develop a tailings disposal facility near the mine.
Avoids the need for permanent waste rock storage facilities. All waste rock generated from mine access development would be returned to the underground workings for stope backfill.
No use of chemical reagents for gold processing at the site.
Dramatically reduces land usage and overall environmental footprint.
Greatly facilitates post-mining closure and reclamation.
Simplifies the environmental review and permitting process.
Ian Klassen, President and CEO comments: "We are extremely pleased to have secured these additional claims for the future mine surface facilities - a key milestone in our work towards preparing for the environmental review and permitting process. As always, our commitment is to exceed all regulatory requirements and environmental expectations while contributing to the local economy and creating long-term job opportunities for the community of Juneau".

Cautionary Statement Regarding Forward-Looking Information
This news release includes certain "forward-looking statements" under applicable Canadian securities legislation. Forward-looking statements include estimates and statements that describe the Company's future plans, objectives or goals, including words to the effect that the Company or management expects a stated condition or result to occur. Forward-looking statements may be identified by such terms as "believes", "anticipates", "expects", "estimates", "may", "could", "would", "will", or "plan". Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties as described in the Company's filings with Canadian securities regulators. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company disclaims any intention or obligation to update or revise any forward-looking information, whether as a result of new information, future events or otherwise, other than as required by law.
Please note that under National Instrument 43-101, the Company is required to disclose that it has not based any production decision on NI 43-101-compliant reserve estimates, preliminary economic assessments, or feasibility studies, and historically production decisions made without such reports have increased uncertainty and higher technical and economic risks of failure. These risks include, among others, areas that are analyzed in more detail in a feasibility study or preliminary economic assessment, such as the application of economic analysis to mineral resources, more detailed metallurgical and other specialized studies in areas such as mining and recovery methods, market analysis, and environmental, social, and community impacts. Any decision to place the New Amalga Mine into operation at levels intended by management, expand a mine, make other production-related decisions, or otherwise carry out mining and processing operations would be largely based on internal non-public Company data, and on reports based on exploration and mining work by the Company and by geologists and engineers engaged by the Company.
