About Midnight Sun Mining Corp.

Midnight Sun is rapidly advancing the Solwezi copper project, with a focus on its flagship Dumbwa copper deposit. The project is located near the town of Solwezi in the heart of the Zambia-Congo copperbelt, the world's second-largest copper-producing region. This prolific mining district is renowned for hosting multiple major copper deposits, and benefits from excellent infrastructure, an established mining work force and a long history of successful production.

The Solwezi copper project is surrounded by producing copper mines, including the geologically similar Lumwana mine just west of the project and First Quantum's Kansanshi mine -- Africa's largest integrated metallurgical processing facility, approximately six kilometres east of the company's recently announced Kazhiba oxide resource. This highly favourable location highlights the district-scale potential of Midnight Sun's land package.

The Dumbwa copper deposit underlies a robust 20-kilometre copper-in-soil anomaly, and continuing drilling has demonstrated strong geological similarities to the nearby Lumwana mine, underscoring the potential scale of this new copper system.

Led by an experienced geological team with a proven record of major discoveries in the Zambia-Congo copperbelt and globally, Midnight Sun has a goal to delineate Zambia's next-generational copper deposit.
