GRANDE PORTAGE RESOURCES DRILLS 9.87 GPT/GOLD OVER 3.39 METERS

(11.1 FT)--- DRILLING NOW EXTENDS GOAT VEIN STRIKE LENGTH TO ALMOST

A KILOMETRE AT THE HERBERT GOLD PROJECT IN S.E ALASKA

VANCOUVER, BC, OCTOBER 31, 2023 – Grande Portage Resources Ltd. (TSX -V “GPG”); (OTCQB:

“GPTRF”); (Frankfurt: “GPB”); (" Grande Portage" or "the Company") is pleased to announce results from

three more diamond drill holes drilled at the Herbert Gold project located in southeast Alaska.

Highlights:

After drilling four holes from the Pad M (please refer to NR dated Sept 14/23) , the rig was moved 285

meters eastward where four more holes were drilled from Pad P. The Company is pleased to confirm that all

Pad P holes successfully targeted the eastern extensions of the Goat vein between 200 and 300 meters below

surface. These holes tested an area of the eastern Goat vein which previously had indications of strong gold

mineralization but only had sparse drilling. The three holes for which assay results have been returned

substantiate that this is a significant gold-bearing region of the Goat and is expected to have a positive impact

on the Company’s future mineral resource calculation.

Hole From To Vein. Intrvl Gold

Name (m) (m) g/t

23P-1 281.00 282.10 Goat 1.10 m 7.66

23P-2 297.00 303.66 Goat 2.83 m 7.753

23P-4 277.21 280.60 Goat 3.39 m 9.871

The Goat vein structure was the target and was intersected in all four holes from this pad. DDH23P-3 also

extended southward past the Goat vein where it intersected a well mineralized section of the Sleeping Giant

vein. Sample analyses from 23P-3 are pending and will be announced in due course.

DDH23P-1 intersected 1.10 meters assaying 7.66 gpt/gold in the Goat vein. This hole was approximately 36

meters below DDH20T-11 (24.0 gpt/gold over 2.1 meters) and 56 meters west of DDH21P-4.

DDH23P-2 intersected 2.83 meters of 7.753 gpt/gold in the Goat vein. This hole was approximately 86

meters below DDH23P-1. This intercept was approximately 15 m eters east of DDH21P-1 and 27 m eters

above DDH20P-1 (9.79 gpt /gold over 0.8 meters). This intersect occurs in a 10 -meter shear zone and

contains a 1.08-meter section which assayed 15.8 gpt/gold in a silicified and micro -brecciated vein riddled

with thin sulfide-rich seams in a hydrothermally altered quartz diorite.

DDH23P-4 intersected 3.39 meters assaying 9.871 gpt/gold including a 1.08-meter interval of quartz vein

assaying 30.8 gpt /gold. This hole was approximately 47 m eters below DDH21P-3 (3.8 gpt /gold over 0.9

meters). At the elevation of this intercept the Goat vein now has approximately 900 meters of strike length

from west to east . Mineralization in the quartz veins consists chiefly of arsenopyrite and to a lesser extent,

pyrite, galena, sphalerite, and sparse visible gold.

The success of the 2023 drilling from the P Pad is highly encouraging because it demonstrates that strong

gold mineralization can be found in the east-west Herbert vein structures the full distance between the

western and eastern boundary faults which effectively terminate the veins. The depth of the veins remains

open, but strong gold values have been intersected in DDH21Q -4 (0.92 meters of 18.93 gpt/gold) at 600

meters below the surface in the Company’s deepest drilling , which indicates that the Company’s resource is

only constrained by the major east and western boundary faults.

After completing drilling at the Pad P, the Company moved the rig to Pad BB, which is the easternmost drill

pad on the property, and completed one hole targeting the Goat vein and the Sleeping Giant vein. Drilling

results are still pending.

Past drilling over many years has confirmed that the Herbert gold project is a high -grade deposit. The chief

primary gold-bearing veins at the Herbert gold project are strong, persistent and extend from the Western

boundary fault to the Eastern fault, a distance averaging nearly one kilometer. Strong gold mineralization has

been identified almost everywhere along these s tructures, both laterally and to the deepest limits of drilling

over the last number of years. Much of the shallower portions of the veins have been tested with good to

superb results. The Herbert Gold veins are classed as a mesothermal high -quartz and low -sulfide style

mineralized system.

Mr. Ian Klassen, President and CEO reports that “Drilling this season certainly assists to fill in certain gaps

within the established resource and adds to the confidence leading into a new resource estimate that will

include the added drilling completed over the recent three-year period. Extending the higher-grade Goat vein

to the east with these three more material intersections is great news.”

QA/QC

All core samples are cleaned and photographed before logging and sampling by a registered professional

geologist. Samples were analyzed at ALS Canada Ltd. at its North Vancouver facilities using conventional

preparation techniques and analyzed using Au -ICP21 for gold with screened metallic analyses for samples

where visible gold was noted. ME -MS41 techniques were used to determine additional element

concentrations. Blanks and standards were inserted in the field as well as in the laboratory with all checks

reporting acceptable results. ALS is independent of the Company and certified ISO-17025.

This news release has been prepared and approved by Carl Hale, CPG, a geologist with more than 40 years of
