Grande Portage Resources Completes Drill Program at The Herbert Gold Project in SE Alaska

Vancouver, British Columbia--(Newsfile Corp. - November 3, 2022) - Grande Portage Resources Ltd. (TSXV: GPG) (OTCQB: GPTRF) (FSE: GPB); ("Grande Portage" or "the Company") is pleased to announce that it has completed its 2022 drill program at the Herbert Gold project in SE Alaska.

The Company completed its 5 deep holes with approximately 3700 metres of drill core. The program targeted both step out and in-fill holes, effectively expanding the database of the established resource and improving the Company's resource parametres.

The Company's drilling continued to test a number of the deposit's primary veins but also penetrated the eastern extensions of the Sleeping Giant and North veins as well as numerous subsidiary veins and structures found within the deposit.

Final sample results are expected throughout December and into 2023 due to continued delays at the assay labs. Lab results will be reported in future disclosures as they are received from the lab and QA/QC has been met. Samples taken for assay are split from the core with a diamond saw with one half being sent to ALS Canada Ltd. an independent lab from the Company. The Company's geologists, who are logging the core have identified certain sections which could contain coarse gold and has marked them for metallic screening which captures the nuggety gold in the assay. Known standards and blanks are inserted into the stream of samples on a regular basis and all core is photographed with a high resolution camera for future viewing.

In addition, the Company confirms that Admiralty Environmental, a Juneau based environmental consultant and water quality laboratory, continued its program of gathering baseline water sampling adding to the company's expanding database from previous years. Results were received this year from several environmental water samples that were collected in 2021 and submitted to the laboratory to test for environmental effects after mining commences. Specifically, the tests determine the potential for mine waste rock to generate acidic run-off and/or harmful concentrations of toxic metals. These and previous tests results conducted in 2020 were extremely positive environmentally showing no tendencies to produce acid rock drainage due to the high inherent carbonate content and the low sulfide content of the host rock and altered wallrock.

Mr. Ian Klassen, President and CEO commented, "The 2022 diamond drill season has been completed and we await the assay results which are expected over the balance of the year and into early 2023. Our 2022 program began late due to unforeseen contractor and supply chain delays. This, coupled with unseasonably poor and foggy weather, further interrupted the Company's original drill plan. That said, our geological team has certainly gained more knowledge into the resource at the Herbert property. Grande Portage is funded for next year's program and management looks forward to adding 2021 & 2022 drill results to the Herbert Gold database."
