Midnight Sun puts second drill to work at Solwezi

Mr. Al Fabbro reports MIDNIGHT SUN PUTS SECOND DRILL TO WORK AT DUMBWA A second diamond drill has commenced work at Midnight Sun Mining Corp.'s flagship Dumbwa target on the Solwezi project in Zambia. As per the company's plans discussed in an Aug. 6, 2025, press release, Midnight Sun has brought in an additional diamond drill rig to expedite the exploration program on Dumbwa. Midnight Sun's president and chief executive officer, Al Fabbro, states: "Our systematic exploration approach is in action and the team are executing with precision. All of our data at Dumbwa suggests an extremely large target area, so we have put a second drill to work in order to expedite the program, which is designed to correlate all previous drilling, new IP data and the extraordinary 20-kilometre soil anomaly that overlays the target with underlying copper mineralization." About Dumbwa Dumbwa represents a near-surface, low-strip, bulk-tonnage exploration target with geology and mineralization closely resembling Barrick's Lumwana mine, approximately 60 kilometres to the west. Dumbwa boasts a high-grade copper-in-soil anomaly extending approximately 20 kilometres along strike and more than one kilometre wide, with peak copper values reaching 0.73 per cent. Previous drilling has confirmed sulphide copper mineralization, but additional drilling guided by structural controls is needed to better define the dip, continuity, size and scale of the system. Multiple stacked mineralized horizons have been identified, which appear to be similar in deposition to those found at the Lumwana mine. The recent dipole-dipole IP survey, covering the southern 11.5 kilometres of the strike extent, has revealed the structural framework of the Dumbwa target, critical for understanding its geometry. The interpreted IP results indicate a horizon that varies from relatively flat-lying and gently dipping, to areas with clear evidence of folding, ranging from open folds to very tight upright folds. There is a strong correlation between the mineralized intervals encountered in prior drilling at Dumbwa and the target horizon interpreted from the IP data. Additionally, a positive relationship exists between this horizon and the overlying soil anomaly. The interpreted IP survey also identified several major crosscutting structures, which help explain offsets between historical soil geochemistry and previously drilled mineralization. Qualified person Darin Labrenz, PGeo, a consulting geologist for the company and qualified person under National Instrument 43-101, has reviewed and approved the technical data and contents of this release. About Midnight Sun Mining Corp. Midnight Sun is focused on exploring the company's flagship Solwezi project, located in Zambia. Situated in the heart of the Zambia-Congo Copperbelt, the second-largest copper-producing region in the world, the company's property is vast and highly prospective. The company's Solwezi project is surrounded by producing copper mines, including Africa's largest copper mining complex right next door, First Quantum's Kansanshi mine. Led by an experienced geological team with multiple discoveries and mines around the world to their credit, Midnight Sun's goal is to find and develop Zambia's next-generational copper deposit. We seek Safe Harbor.
