Midnight Sun Announces Kazhiba Target 2 Drilling Underway

Vancouver, British Columbia--(Newsfile Corp. - June 5, 2025) - Midnight Sun Mining Corp. (TSXV: MMA) (OTC Pink: MDNGF) ("Midnight Sun" or the "Company") is pleased to report that diamond drilling is underway at the Kazhiba Target 2 sulphide copper target on the Company's Solwezi Project in Zambia.

Midnight Sun's President & CEO, Al Fabbro, states "Kazhiba Target 2 represents an exciting opportunity to reach a major new milestone for Midnight Sun. By utilizing a phased sequence of exploration methods, we have checked all the boxes to prepare for this initial drill program, and I am extremely excited for the results of the hard work being done by our technical team."

The planned six to eight diamond drill holes totalling approximately 1,000 metres are designed to test the ~four-kilometre by two-kilometre Kazhiba sulphide copper target, where the Company has identified an overlapping copper signature in Partial Ionic Leach testing, a strong VTEM geophysical anomaly, and high chargeability / low resistivity responses from induced polarization geophysics all coinciding with geology consistent to most deposits in the Zambian Copperbelt. A water supply borehole has been completed, and the company is now underway with the first diamond drill hole, which is KAZ-25-003, and has a target depth of 150 metres.

Additionally, geochemical sample collection at Mitu has been completed. The samples are now being prepared for Partial Ionic Leach assaying at ALS Chemex.
