Recently Completed Drill Program At Herbert Gold Project

VANCOUVER - Grande Portage Resources Ltd. reported additional assay results from the recently completed drill program at its Herbert Gold Project located in S.E Alaska. Drilling from the U Pad in 2020 mainly targeted the Deep Trench Vein but also intersected the Main Vein at mid-depths (-40 to -80 meters elev.) near the eastern limits of previous drilling and the Ridge Vein. All four holes from U Pad hit strong shearing and hydrothermal alteration at the intersections with the Main Vein with gold values ranging from 11.466 g/t over 2.38 meters to 1.38 g/t over 1.41 meters in 20U-4.

A strong intercept on the Ridge Vein in 20U-1 yielded 1.48 meters of 29.21 g/t Au and another in 20U-4 showed 1.4 meters of 16.53 g/t Au with visible gold in the core. These two intercepts are approximately 70 meters apart east to west. The Ridge Vein is an intermediate vein situated in the structural block between the larger Goat and Main Vein structures. The targeted area of the Deep Trench Vein was beyond the eastern limits of previous drilling and at depth. Holes 20U-1 & 2 and 20H-1 through 3 hit the vein with the results shown in the chart above. The best intercept was in 20H-3 with 4.50 meters of 11.773 g/t Au with visible gold in the core. This weighted assay includes a sample showing 0.77 meters of 51.26 g/t.

The Company drilled 8375 meters in 2020 with two drill rigs and placed holes into the North Vein, Goat Vein, Sleeping Giant and Ridge Veins, Main Vein, Deep Trench, Floyd and Elusive Veins and numerous subsidiary veins and structures in between. New incoming sample results are expected throughout December and into January Assay processing from the lab has been especially slow this year due to Covid-19 related protocols.

Ian Klassen, President, said, "These holes continue to add confidence that this system is pervasive and will continue to grow. All veins drilled have encountered mineralized material. Mesothermal veins are usually less than two meters wide and often occur in parallel sets just as they are presented at the Herbert deposit."

Additional 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 geologist who is 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.
