GRANDE PORTAGE RESOURCES STAKES ADDITIONAL CLAIMS

EXPANDING HOLDINGS AT THE HERBERT GOLD PROJECT

VANCOUVER, BC, August 2 , 202 2 – Grande Portage Resources Ltd. (TSX -V “GPG”); (OTCQB:

“GPTRF”); (Frankfurt: “GPB”); (" Grande Portage" or " the Company ") announces the staking of 10

additional unpatented mining claims for its Herbert Gold project (the “Project”), continuously adjoining the

northeast corner of the property.

The new claims were staked to cover the north -eastern extension thereby ensuring a continuation of the

prospective ground held by the Company and its drilling efforts to expand upon its resource. The vein

structures and mineralization show no signs of diminishing with depth, and that the host rock unit containing

the mineralized veins dips to the northeast between two major bounding faults.

The Company’s current drill program is underway and will continue until November 2022.

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

experience and a Qualified Person as defined under NI #43-101.

About Grande Portage:

Grande Portage Resources Ltd. is a publicly traded mineral exploration company focused on the Herbert

Gold discovery situated approximately 25 km north of Juneau, Alaska. The Company holds a 100% interest

in the Herbert property. The Herbert Gold property system is open to length and depth and is host to at least

six main composite vein -fault structures that contain ribbon structure quartz -sulfide veins. The project lies

prominently within the 160km long Juneau Gold Belt, which has produced over seven mill ion ounces of

gold. The Company’s updated NI#43 -101 Mineral Resource estimate reported at a base case mineral

resources cut -off grade of 3.0 grams per tonne gold (g/t Au) and consists of: an indicated resource of

1,196,800 ounces of gold at an average gra de of 10.23 g/t Au (3,637,000 tonnes); and an inferred resource of

325,900 ounces of gold at an average grade of 8.91 g/t Au (1,138,000 tonnes), as well as an Indicated resource

of 686,700 ounces of silver at an average grade of 5.87 g/t Ag (3,637,000 tonn es); and an inferred resource of

169,300 ounces of silver at an average grade of 4.63 g/t silver (1,138,000 tonnes).

The resource assumes underground mining techniques, a gold price of $1,300 and are reported at a 2.5 gpt

cut-off. Composites were capped at 125 gpt. Mineral Resources are not Mineral Reserves and do not have

demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be

converted to Mineral Reserves. The estimate of Mineral Resources requires a ssumptions that are believed to

be reasonable and may be materially affected by environmental permitting, legal, title, sociopolitical,

marketing or other relevant issues.
