Midnight Sun Closes $10 Million Non-Brokered Private Placement

Vancouver, May 23, 2024 - Midnight Sun Mining Corp. (TSXV: MMA) (OTC Pink: MDNGF) (the "Company" or "Midnight Sun") is pleased to announce that the Company has now closed its previously announced non-brokered private placement (the "Offering") for gross total proceeds of $10,000,000. Under the Offering, the Company sold 45,454,544 units of the Company (each, a "Unit") at a price of $0.22 per Unit.

"Midnight Sun is now sufficiently funded to execute on all of our exploration plans," stated Al Fabbro, Midnight Sun's President & CEO. "Over the last 12 months, we have pulled the plans for our Solwezi Project into sharp focus. Starting with our USD $15.5 million earn-in with KoBold Metals announced in February, which moves our Dumbwa Target forward, and followed by the recent announcement of a cooperative exploration plan with First Quantum Minerals to advance near surface oxide-copper targets toward potential near-term cash flow. We have a two-fold attack plan underway, comprised of aggressive drill campaigns on two separate key targets, designed to demonstrate the tremendous value of our copper project, all underpinned by a very significant financing."

Each Unit consists of one common share of the Company ("Common Share") and one common share purchase warrant ("Warrant"). Each Warrant will entitle the holder to purchase one Common Share for a period of 36 months following the closing date of the Offering at an exercise price of $0.33 per share.

The net proceeds of this offering will be used by the Company to fund exploration work on its projects located in Zambia, as well as general working capital.

Canaccord Genuity Corp., Red Cloud Securities Inc., and Haywood Securities Inc., acted as finders for the Company under the Offering.

Finder's fees of $426,788 will be paid in cash and 1,962,530 Finder's Warrants will be issued in connection with the Private Placement. 1,374,337 Finder's Warrants each entitle the Finder to purchase one Common Share of the Company for a period of thirty-six months from closing, at an exercise price of $0.33 and 588,193 of the Finder's Warrants each entitle the Finder to purchase one Common Share of the Company for a period of thirty-six months from closing, at an exercise price of $0.22.
