Grande Portage Resources Announces Signing of Drill Agreement and Mobilization

Vancouver, June 16, 2021 - Grande Portage Resources Ltd. (TSXV: GPG) (OTCQB: GPTRF) (FSE: GPB) ("Grande Portage" or "the Company") is pleased to announce that it is taking the necessary steps to prepare for its upcoming drill season at the Herbert Gold project in SE Alaska.

As previously announced, the Company has received all permits and all other regulatory approvals to proceed this season. NASCO Industrial Services and Supply ("NISS") has been engaged to drill up to 24,000 feet of diamond drill core on the Company's Herbert gold project.

The upcoming drill program, expected to start in the next two weeks, will test multiple targets from up to nine platforms. The Company intends to;

• test the eastern extensions of the Goat vein
• expand coverage of the western, central and eastern portions of the Deep Trench and Main veins
• drill deeper to expand coverage on the Main vein
• expand drill testing of the newly discovered Sleeping Giant vein, where in 2020 the Company encountered assays including:
  • DDH 20T-7 reported 50.84 gpt gold over 1.3m;
  • DDH 20T-2B reported 43.03 gpt gold over 1.5m.

Ian Klassen, the Company's CEO remarked, "We are very excited to start this season's drill program, with NISS, a first class operator, especially on the heels of our recently announced NI resource calculation. Our geological team, led by Carl Hale is very optimistic about the continued opportunities to expand the Herbert resource, a high grade gold project with tremendous growth potential."

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.
