Completion 2021 Drill Program At Herbert Gold Project

VANCOUVER - Grande Portage Resources Ltd. has completed its two rig drill program at the Herbert Gold project in SE Alaska. The Company completed 19 holes and approximately 8150 meters of drill core which included both step out and in-fill holes, effectively expanding the parameters of the established resource and improving the company's knowledge base.

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

Final sample results are expected throughout November, December and into 2022 due to continued delays at the assay labs principally due to protocols of the ongoing COVID-19 pandemic. 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 Bureau Veritas Labs, Richmond, B.C., an independent lab from the Company. The Company's geologists who are logging the core identifies certain sections which could contain coarse gold and marks them for the special preparation procedure of 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. Additionally, all core is photographed with a high resolution camera for future viewing.

Several samples were also collected 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. Previous tests 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.
