GRANDE PORTAGE RESOURCES COMMENCES BASELINE ENVIRONMENTAL

SAMPLING AT ITS HERBERT GOLD PROJECT IN S.E. ALASKA

VANCOUVER, BC, April 12, 202 1 – Grande Portage Resources Ltd. (TSX -V “GPG”); (OTCQB:

“GPTRF”); (Frankfurt: “GPB”); (" Grande Portage" or " the Company") is pleased to announce that it has

engaged Admiralty Environmental, LLC , Core Geoscience LLC , and Jade North LLC. to assist and oversee

the collection of baseline data that a developer would need for future mine development at the Herbert Gold

Project. Data such as acid/base accounting, water and air quality , and other data requiring longer sampling

and analytical times are being initiated. This data will form part of any future environmental assessment on

the project . Consultations with the US Forest Service, Alaska Department of Natural Resources, Alaska

Department of Fish and Game, Alaska , Department of Environmental Conservation , and other authorizing

agencies will be conducted to confirm compliance with all regulations.

Ian Klassen, President and CEO state d “These long lead data points are required of any evolving future

mining asset and are critical in de-risking the project. While it is impossible to confirm the direction of any

environmental assessment until the size parameters and scope of a project is fully defined, the baseline data

required for any EA or EIS will include the data being acquired. This new initiative will add val ue to the

project by advancing such studies”.

In addition, leading up to its 2021 field season, the Company conf irms that it has Department of Natural

Resources’ permit authorizations (APMA 3049 and the Temporary Water Authorization ) as well as its Fish

Habitat Permit and the City & Burrough of Juneau Development Permit. The Company expects to receive

its 2021 USFS Decision Memorandum shortly.

(g/t Au) and consists of: An indicated resource of 606,500 ounces of gold at an average grade of 10.03 g/t Au

(1,880,500 tonnes); and an inferred resource of 251,700 ounces of gold at an average grade of 14.15 g/t Au

(553,429 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 assumptions

that are believed to be reasonable and may be materially affected by environmental permitting, legal, title,

sociopolitical, marketing or other relevant issues.
