Midnight Sun Announces Cooperative Oxide-Copper Exploration Plan

Vancouver, British Columbia, April 23, 2024 – Midnight Sun Mining Corp. (the “Company”

or “Midnight Sun”) (TSX-V: MMA / OTC: MDNGF) is pleased to announce that a cooperative

exploration plan has been established between the Company and First Quantum Minerals

Ltd. (“First Quantum” ) to jointly define potential feed source s for First Quantum ’s SX/EW

oxide copper circuit at the Kansanshi Mine.

Midnight Sun will work closely with First Quantum to delineate and evaluate the potential

grade and metallurgy of the possible oxide ore types. Exploration work on oxide copper

targets across the Solwezi Project is anticipated to start in Q2 2024, with an initial focus on

the Kazhiba Dome target, where previous drilling intercepted 14 .2 me tres of 5.71% Cu, 24

metres of 3.15% Cu, and 8 metres of 5.14% Cu*. Prior work on the Solwezi Project outlined

multiple high-grade zones of oxide copper mineralization.

“Through exploration work carried out across our Solwezi Project , we have outlined

numerous areas of high-grade oxide copper mineralization at or near surface. Previously,

we had considered oxide intercepts as pathfinders in our exploration for large sedimentary

copper targets at depth . Now, a remarkable opportunity to utilize this oxide material has

been identified , which could put Midnight Sun in a position to become a near -term

producer.” stated Al Fabbro, Midnight Sun’s President & CEO. “First Quantum’s Kansanshi

Mine has depleted oxide reserves and is transitioning to a large sulphide development . In

the meantime, they have capacity potential to process oxide ore. Our property is just a few

kilometres from their mine gate , and an existing haul road owned by First Quantum

connects the two. Using oxide copper ore from our property, First Quantum may be able to

enhance feed grades and utilize sulfuric acid produced by their on -site smelter. In turn,

Midnight Sun would be in a position to receive significant near-term positive cash flow from

the throughput of material from our property . We are thrilled to have found a win -win

situation tha t represents such significant benefits to both Midnight Sun and First

Quantum.”

In parallel with KoBold Metals’ (“KoBold”) work on the Dumbwa Target area, Midnight Sun’s

2024 exploration plans will be focused on this cooperative exploration program to

delineate oxide copper on multiple areas of our Solwezi Project. Phase one of this program

is expected to begin at the Kazhiba Dome, which is located less than 10 kilometres from the

Kansanshi Mine gate.

*All results have been previously reported. Stated widths are downhole widths. True widths

are estimated to be 70%-90% of downhole widths

About Midnight Sun

Midnight Sun is focused on exploring our flagship Solwezi Project, located in Zambia.

Situated in the heart of the Zambia -Congo Copperbelt, the second largest copper

producing region in the world, our property is vast and highly prospective. Our Solwezi

Project is surrounded by world -class 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 intends to find and develop Zambia’s next generational copper

deposit.
