Midnight Sun Bets on Dumbwa as Copperbelt’s Next Major Discovery

VANCOUVER, British Columbia – May 14, 2026 – Midnight Sun Mining Corp. is set to pull back the curtain on what it believes could be Zambia’s next major copper discovery. The company has invited shareholders and investors to a critical technical webinar on May 19th, offering a deep dive into the promising drill results from its flagship Dumbwa copper deposit.

The event will feature Chief Operating Officer, Dr. Kevin Bonel, a seasoned geologist with extensive experience in the region. This webinar moves beyond typical corporate updates, promising to deliver detailed geological context and interpretation of the project's progress. For investors tracking the junior mining space, this is a key opportunity to assess the substance behind the company's ambitious claims within one of the world's most important copper jurisdictions.

High-Grade Hits Fuel Exploration Fire

At the heart of the upcoming discussion are the recent drill results that have ignited interest in the Dumbwa deposit. Throughout late 2023 and early 2024, Midnight Sun has consistently reported intercepts of high-grade copper mineralization that stand out in the industry.

Notable results from the Dumbwa Central and Dumbwa East targets included intercepts such as 2.50% copper over 11.20 meters and 2.40% copper over 13.50 meters, with concentrated zones hitting as high as 4.88% copper over 5.20 meters. In a sector where many large-scale mines operate on grades below 1%, these figures are significant. They not only confirm the presence of rich mineralization but also demonstrate continuity, suggesting the potential for a robust and economically viable system.

These drill results are not isolated finds. They fall within a massive 20-kilometer-long copper-in-soil anomaly, a vast surface footprint that has guided the company's exploration strategy and hints at the district-scale potential of the underlying deposit. The webinar is expected to connect the dots between this large anomaly and the high-grade intercepts, building a comprehensive geological model for attendees.

Location is Everything: In the Heart of Copper Giants

Midnight Sun's Solwezi Project is strategically positioned in the heart of the Zambia-Congo Copperbelt, the planet's second-largest source of copper. This isn't just a geographical footnote; it's a fundamental pillar of the project's value proposition. The property is surrounded by some of Africa's most significant mining operations.

To the west lies Barrick Gold's Lumwana mine, a massive operation to which Dumbwa shares "strong geological similarities," according to the company. Just six kilometers to the east is First Quantum Minerals' Kansanshi mine, Africa's largest copper mine by production. Operating in the shadow of these giants provides Midnight Sun with unparalleled advantages. The region boasts established infrastructure, including power and transportation networks, and a skilled local workforce with generations of mining experience.

Furthermore, the project benefits from a favorable political climate. The Zambian government has publicly stated its goal to triple the country's annual copper output to 3 million tonnes, actively encouraging foreign investment and streamlining the mining sector to achieve this ambitious target. This pro-mining stance creates a stable and supportive environment for exploration companies like Midnight Sun to advance their projects from discovery to potential production.

Expert Guidance and a Proven Geological Model

Leading the technical presentation is COO Dr. Kevin Bonel, whose credentials lend significant weight to the company's exploration efforts. With a Ph.D. in Economic Geology and over two decades of experience, including senior roles with major players like Anglo American on the African continent, Dr. Bonel brings a deep understanding of the Copperbelt's complex geology. His leadership provides investors with confidence that the exploration program is being guided by rigorous scientific methodology.

A key aspect of this methodology is the comparison to the nearby Lumwana mine. Lumwana is a classic example of a large, sediment-hosted stratiform copper deposit, a style of mineralization characteristic of the Copperbelt. By drawing parallels, Midnight Sun is suggesting that Dumbwa has the potential to be a similar large-tonnage system. This geological analogy serves as a powerful de-risking tool, leveraging the known success of a neighboring world-class mine to build a case for Dumbwa's potential scale. The webinar will likely elaborate on the specific shared characteristics, from rock types to structural controls, that underpin this compelling comparison.

Tapping into a Surging Copper Market

Midnight Sun's focused exploration comes at a pivotal moment for the global copper market. The metal is a cornerstone of the global energy transition, essential for everything from electric vehicles and charging infrastructure to wind turbines and solar panels. As the world electrifies, demand for copper is forecast to surge.

Simultaneously, the supply side is facing significant challenges. Years of underinvestment in exploration and the increasing difficulty of developing new mines have led analysts to predict substantial supply deficits in the coming decade. This looming supply-demand imbalance has pushed copper prices to multi-year highs, creating a highly favorable environment for companies capable of bringing new, high-quality deposits online.

In this context, the May 19th webinar is more than just a project update; it is a direct appeal to a market hungry for new discoveries. By offering a transparent, data-driven look at the Dumbwa deposit, Midnight Sun is providing investors with the technical details needed to evaluate a ground-floor opportunity in a critical commodity sector. The live question-and-answer session with management will further enable stakeholders to probe the company's strategy and vision for advancing what could become a significant new source of copper for a world that desperately needs it.
