(FSE: GPB) (“Grande Portage” or the “Company”) is pleased to report updates regarding its New Amalga Gold Project in
Southeast Alaska.
The project remains open to expansion in multiple directions and hosts an Indicated Resource of 1,438,500 ounces of gold at

On November 5th Grande Portage will present a project overview during the “Advanced Exploration Projects” session of the
Alaska Miners Association annual convention in Anchorage. This conference is the premier gathering for the mining industry
in Alaska and includes representatives from operating mines, advanced development projects, early-stage exploration prospects,
vendors, regulators and investors.
Grande Portage’s presentation, titled “ New Amalga Gold Project – Developing an Ultra -Low-Footprint Underground Mine in Southeast

currently being evaluated in the company’s ongoing Preliminary Economic Assessment, scheduled for completion in February
2026.

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 pla ce 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.
