GRANDE PORTAGE RESOURCES ANNOUNCES CORPORATE UPDATES

Grande Portage Resources Ltd.'s drill contractor, Nasco Industrial Services and Supply, has confirmed that its drill rig and necessary equipment and supplies have arrived at the company's staging area in Juneau, Alaska.

NISS, whose clients include Hecla Mining, First Majestic Silver and Rio Tinto, has been engaged to drill up to 25,000 feet of diamond drill core on the company's Herbert gold project. The drill program will target many geologically promising high-value targets at the Main, Goat, Deep Trench, Ridge and Sleeping Giant veins from multiple locations. The coming drill program is fully permitted and fully financed.

In addition, the company confirms that Cox Environmental Services, a Juneau-based environmental water quality consultant, has been engaged to continue the company's dedicated program of gathering baseline water sampling adding to its expanding database. Previous tests results from 2020, 2021 and 2022 confirm that there are no tendencies to produce acid rock drainage due to the high inherent carbonate content and the low sulphide content of the host rock and altered wall rock.

Ian Klassen, president, remarked: "We are ready to recommence field activities with our experienced and dedicated team of professionals. The company is well financed and has a comprehensive drill plan for 2023."

The company also announces that it has closed a non-brokered private placement with the issuance of 5.55 million units at a price of 20 cents per unit for gross proceeds of $1.11-million, with all securities issued having a four-month hold period, which expires on Sept. 10, 2023.

Each unit in this offering consists of one common share in the capital of the company and one share purchase warrant. Each whole warrant entitles the unit holder to purchase one additional Grande Portage common share at a price of 30 cents per share at any time within 24 months of the closing.

No finders' fees were paid in conjunction with this non-brokered placement.

The net proceeds of the offering will be used to advance exploration activities at the company's Herbert gold project and for general working capital.

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 National Instrument 43-101.
