Grande Portage to Present at 2025 Alaska Miners Association Annual Convention

The most recent news release from Grande Portage Resources Ltd. dated November 3, 2025, states the company will present at the 2025 Alaska Miners Association Annual Convention on November 5, 2025. The presentation will focus on the New Amalga Gold Project's development as an "ultra-low-footprint underground mine."

Key updates within the release include: - A reiteration of the project's mineral resource estimate (Indicated 1,438,500 ounces gold at 9.47 g/t Au and Inferred 515,700 ounces gold at 8.85 g/t Au), emphasizing that the project remains open to expansion. - Confirmation that the Preliminary Economic Assessment (PEA) for the project is scheduled for completion in February 2026. - Engagement of RESPEC Inc. to conduct roadway and traffic studies for ore haulage on Glacier Highway to Cascade Point and for mining cost estimation for the PEA. - A grant of 2,200,000 incentive stock options to directors, officers, and consultants. These options have an exercise price of $0.25 CAD and a five-year term, subject to TSX Venture Exchange approval.

The most recent news is largely a confirmation of ongoing activities and previously disclosed information, rather than a new material development.

The reiteration of the resource estimate and the PEA completion timeline (February 2026) is in line with expectations set by the October 20, 2025, news release, which announced the initiation of the PEA. This confirms the company is progressing as planned, but it does not provide new information to materially alter the company's valuation.

The engagement of RESPEC Inc. for specific studies (roadway, traffic, and mining cost estimation) is a necessary and routine step in advancing the PEA. It reinforces the company's commitment to its chosen development concept of off-site processing via Cascade Point, which was a positive strategic decision outlined in prior news. However, this is an operational detail of the PEA process, not a standalone material catalyst.

The granting of 2.2 million incentive stock options to insiders and consultants is a routine corporate compensation practice. While dilutive to existing shareholders (representing approximately 1.45% of the current outstanding shares), its impact is not considered material in the context of the company's overall share structure and stage of development. Notably, these options appear to have been included in the July 31, 2025, financial statements released on September 26, 2025, indicating a lag in public announcement compared to internal accounting. The exercise price of $0.25 CAD is slightly above the last trading price of $0.24 CAD, making them slightly out-of-the-money but close to current levels.

Overall, this news provides incremental positive reassurance regarding project execution but does not introduce new information that would warrant a significant re-rating of the stock. It is a follow-up to the materially positive announcement of PEA initiation and indicative off-take terms from October 20, 2025.

Grande Portage Resources Ltd. (GPG) is a Canadian mineral exploration company focused on gold and silver. Its flagship asset is the New Amalga Gold Project, located in Southeast Alaska, approximately 25 kilometers north of Juneau, Alaska. The project was formerly known as the Herbert Gold Project and holds a 100% interest for Grande Portage. Geologically, it is situated within the 160-kilometer-long Juneau gold belt, which has historically produced over eight million ounces of gold.

The New Amalga Project has an NI 43-101 compliant mineral resource estimate (effective July 2024, based on a 2.5 g/t gold cut-off) of: - Indicated Resource: 4,726,000 tonnes containing 1,438,500 ounces of gold at an average grade of 9.47 g/t Au, and 891,600 ounces of silver at 5.86 g/t Ag. - Inferred Resource: 1,813,000 tonnes containing 515,700 ounces of gold at an average grade of 8.85 g/t Au, and 390,600 ounces of silver at 7.33 g/t Ag. The company states the gold system remains open to length and depth, with potential for expansion.

The proposed development concept for New Amalga is a small-footprint underground mining operation that utilizes third-party off-site processing. This strategy aims to significantly reduce on-site capital expenditures by eliminating the need for a processing plant and tailings disposal facility. Recent sensor-based ore sorting testwork showed promising results, achieving a 120% gold grade increase and 57% mass reduction with minimal gold loss, which supports the viability of this direct-ship operation model. The project's proximity to tidewater and an existing paved highway is crucial for this logistics strategy. The company is currently conducting a Preliminary Economic Assessment (PEA), with final completion targeted for February 2026.
