Grande Portage Receives US Forest Service Special Use Permit for

Environmental Infrastructure at the New Amalga Gold Project

Vancouver, British Columbia — January 6, 2026 – Grande Portage Resources Ltd. (TSXV: GPG) (OTCQB: GPTRF) (FSE:

GPB) (“Grande Portage” or the “Company”) is pleased to announce an update regarding permitting for its New Amalga Gold

property in Southeast Alaska. The current development concept for the project envisions a small-footprint underground mining

operation with third-party offsite processing, eliminating the need for an onsite mill or tailings storage facility.

On January 5th, the Company received a fully executed Special Use Permit from the US Forest Service (USFS) which authorizes

the installation of key long-term infrastructure related to environmental monitoring, including:

• An environmental data collection station at the expected location of the mine’s surface facilities to gather critical

meteorological data as necessary for key future permits including an Alaska Department of Conservation Air Quality

Control permit and Alaska Pollutant Discharge Elimination System (APDES) permit.

• Additional meteorological monitoring equipment above the potential future location of underground workings.

• Stream gauging sensors to understand seasonal fluctuations in river levels and support design of a mine water treatment

and handling system which is protective of fish habitat.

• Satellite uplink communications and power infrastructure necessary for system operation.

Ian Klassen, President and CEO comments: "The receipt of this Special Use Permit is a key step towards gathering all the data

necessary to design and permit a low -footprint mining operation which is protective of the surrounding environment. This is

an important milestone as it represents the project’s first instance of receiving permits for installation of long-term infrastructure

at the project site , intended to be utilized not only for preproduction studies but also for ongoing monitoring throughout

construction and operation of a future mine facility. We would like to thank our local regulatory officials at the US Forest

Service and particularly the USFS staff brought back from furlough for their work advancing this permit during the recent US

Federal Government shutdown.”

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 smal l-footprint underground

mining operation which would transport material offsite for processing by a third party, eliminating the need for an onsite gold

recovery plant or tailings storage facility.

This setup is designed to provide several benefits:

• Eliminates the need to build a gold recovery plant, minimizing mine footprint, power requirements and reducing project

construction CAPEX.

• Eliminates the need to develop a tailings disposal facility at the site, as no tailings would be generated.

• Removes the need for permanent waste rock storage facilities. Waste rock generated from mine development would

be returned to the underground workings as 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.

Project highlights:

• A 100% interest in the New Amalga Gold Project, located near infrastructure only 25km north of Juneau, Alaska and

6km from paved all-season highway (Fig. 2)

• The property is host to at least 8 large, long, gold bearing mesothermal veins

• 240 drill holes from 55 platforms totaling ~65,000 m confirm a large gold-quartz system

• Past drilling produced multi-ounce assays on several veins. Select samples include:

Deep Trench Vein: 15.3m grading 37.1 g/t Au, 8.3m grading 58.6 g/t Au, 11.6m grading 28.3 g/t Au

Goat Vein: 2.1m grading 74.2 g/t Au, 6.3m grading 15.7 g/t Au

Main Vein: 3.1m grading 79.2 g/t Au, 2.1m grading 37.2 g/t Au, 3.1m grading 13.9 g/t Au

Ridge Vein: 1.5m grading 43.0 g/t Au, 1.5m grading 29.2 g/t Au

Sleeping Giant Vein: 2.1m grading 15.4 g/t Au , 3.2m grading 20.7 g/t Au

See Fig. 1 below for approximate locations of selected intercepts.

• The Company's updated NI43-101 Mineral Resource Estimate (MRE) with an effective date of July 17, 2024

reported 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 deposit is open to the north, south and at depth.

• Goat vein surface outcrop channel samples assayed 129.02 g/t gold (3.76 opt) and 290 g/t gold (8.46 opt) with 224

g/t silver (6.53 opt)

• LiDAR survey of property discovered numerous targets - the first of these tested confirmed gold discovery

• Received excellent metallurgical recoveries up to 98.2%

• Completed 6+ years of environmental baseline water sampling

• Current development strategy envisions a small-footprint underground mining operation with third-party offsite

processing, eliminating the need for an onsite mill or tailings storage facility. This configuration reduces capital costs,

greatly minimizes the project’s environmental footprint, and facilitates permitting.

• LOI signed with Goldbelt Inc (an Alaska Native Corporation organized under the Alaska Native Claims Settlement

Act) for development of an ore export terminal at Cascade Point, Goldbelt’s privately-held parcel located only 22km

from the project site.

• NI43-101 Preliminary Economic Assessment in progress, expected completion 2026 Q1.

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 forw ard-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.
