MIDNIGHT SUN ANNOUNCES COOPERATIVE OXIDE-COPPER EXPLORATION PLAN

A co-operative exploration plan has been established between Midnight Sun Mining Corp. and First Quantum Minerals Ltd. to jointly define potential feed sources for First Quantum's SX/EW (solvent extraction/electrowinning) 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 metres 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 that 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.

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.

We seek Safe Harbor.
