Arizona Tribune - Grande Portage Resources Files 2026 Plan of Operations / Drill Permit with the US Forest Service

Subject to regulatory approval, the proposed program for 2026 includes up to 4,300 meters of diamond drilling from up to 14 drillholes, as well as installation of instrumentation, surface mapping, and trench sampling. The drillholes will provide additional definition to upgrade resource classification in key areas of the deposit and will characterize the geotechnical and hydrogeological aspects of the rock mass in order gather data necessary for the environmental review and permitting process as well as to inform mine development plans.

The geotechnical and hydrogeological characterization work will include:

• Detailed geotechnical logging to define the rock conditions in areas of key underground infrastructure,

• Installation of piezometers in select drillholes to measure groundwater levels and pressures, and

• Packer testing, which involves pumping pressurized water into a drillhole to determine the hydraulic conductivity or permeability of the rock structures intersected by the hole

Ian Klassen, President and CEO comments: "The filing of the 2026 Plan of Operations marks an important milestone for the New Amalga project as it advances to a mix of exploration and development. For the first time, drilling will be gathering the critical geotechnical and hydrogeological data necessary to inform engineering and environmental studies. This is a key step to enable the project to advance through the regulatory process and towards mine development."

Mr. Klassen continued: "We would like to thank our local regulatory officials at the US Forest Service, several of whom were brought back from furlough during the recent US Federal Government shutdown in order to continue advancing the permits for New Amalga and other mining projects in the region. This is a strong and welcome signal that the US Federal government and the US Forest Service consider permitting efforts for New Amalga to be a top priority due to the economic benefits the project will bring to the region."

The New Amalga Gold Project remains open to expansion in multiple directions and hosts an Indicated Resource of 1,438,500 ounces of gold at an average grade of 9.47 g/t Au (4,726,000 tonnes) and an Inferred Resource of 515,700 ounces of gold at an average grade of 8.85 g/t Au (1,813,000 tonnes). The current development concept envisions a small-footprint underground mining operation with third-party offsite processing, eliminating the need for an onsite mill or tailings storage facility.

About Grande Portage:

Grande Portage Resources Ltd. is a publicly traded mineral exploration company focused on advancing the New Amalga Mine project, the outgrowth of the Herbert Gold discovery situated approximately 25 km north of Juneau, Alaska. The Company holds a 100% interest in the New Amalga property. The New Amalga gold system is open to length and depth and is host to at least six main composite vein-fault structures that contain ribbon structure quartz-sulfide veins. The project lies prominently within the 160km long Juneau Gold Belt, which has produced over eight million ounces of gold.

The Company's updated NI#43-101 Mineral Resource Estimate (MRE) reported at a base case mineral resources cut-off grade of 2.5 grams per tonne gold (g/t Au) and consists of: an Indicated Resource of 1,438,500 ounces of gold at an average grade of 9.47 g/t Au (4,726,000 tonnes); and an Inferred Resource of 515,700 ounces of gold at an average grade of 8.85 g/t Au (1,813,000 tonnes), as well as an Indicated Resource of 891,600 ounces of silver at an average grade of 5.86 g/t Ag (4,726,000 tonnes); and an Inferred Resource of 390,600 ounces of silver at an average grade of 7.33 g/t silver (1,813,000 tonnes). The MRE was prepared by Dr. David R. Webb, Ph.D., P.Geol., P.Eng. (DRW Geological Consultants Ltd.) with an effective date of July 17, 2024.

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.

NEITHER THE TSX VENTURE EXCHANGE NOR ITS REGULATION SERVICE PROVIDER (AS THAT TERM IS DEFINED UNDER THE POLICIES OF THE EXCHANGE) ACCEPTS RESPONSIBILITY FOR THE ADEQUACY OR ACCURACY OF THIS NEWS RELEASE
