Vancouver, British Columbia--(Newsfile Corp. - June 30, 2020) - Grande Portage Resources Ltd. (TSXV: GPG) (OTCQB: GPTRF) (FSE: GPB) ("Grande Portage" or "the Company") is pleased to announce that it has commenced drilling, using two 12 hour shifts per day, at its Herbert Gold project in S.E. Alaska.

Grande Portage intends to drill approximately 18-20 holes from up to four different platforms which will test up to four separate major veins and their satellite structures. The 2020 drill program is a continuation of previous drilling which successfully tested multiple gold-quartz veins of the Herbert mesothermal vein system with very encouraging results. The current drill program will test targets focusing on the expansion of the gold-bearing Goat, Main and Deep Trench veins. It will also test the Floyd vein and the newly discovered Elusive vein which was identified by LiDAR and verified on surface as a quartz vein bearing visible gold.

Ian Klassen, Grande Portage's CEO, remarked, "We are excited to commence our much anticipated summer drill program at the Herbert gold project in Alaska. The Company has generated many very encouraging high-grade drill results in each of its previous drill campaigns. We are now well positioned to follow up on this summer's drilling program which is entirely focused on expansion."

In addition, the Company announces that subject to TSX Venture Exchange approval, it has granted incentive stock options to various directors, officers and consultants to purchase up to 650,000 common shares exercisable on or before June 30^th, 2025 at a price of $0.35 per share.
