Midnight Sun Drills 0.89% Copper Over 25 Metres and 1.36% Copper Over 6 Metres within 0.46% Copper Over 50 Metres; Continuing to Significantly Extend Dumbwa System

Highlights of Drilling include:

• DBW-25-021 intercepted 0.89% Cu over 25m. 4 separate mineralized zones were intercepted within the hole.

• DBW-25-030 intercepted 0.46% Cu over 50m, including 1.36% Cu over 6m.

• DBW-25-027 intercepted 0.48% Cu over 21.85m

Midnight Sun’s COO, Kevin Bonel, states “Similar to the nearby Lumwana Mine, delineating basement-hosted copper systems like Dumbwa requires defining continuous, shallow mineralization along extensive strike at surface, and these latest intercepts continue to do exactly that. Each hit strengthens our confidence in the Dumbwa system and further validates our thesis. Our strategy of methodically delineating Dumbwa in 100 to 200 metre increments along strike has proven to be the right strategy to rapidly reveal the true scale of this copper system. We are advancing quickly, hitting consistent copper mineralization that mirrors what my team encountered as we expanded Lumwana. With drilled strike length now exceeding 3.6 kilometres with exceptional continuity, we are efficiently tracking the system and delineating it with precision. As the strike continues to grow, each step-out makes Dumbwa larger, stronger, and increasingly compelling.”

Dumbwa Drill Program Update

The drilling at Dumbwa has now demonstrated 3.6 kilometres of north-south mineralized strike. To date, 122 holes have been completed with 5 holes ongoing and a further 140 holes called for in the immediate plan to test the mineralized corridor over the next 3 kilometres of strike. This represents approximately 25,000 metres of planned drilling.

Samples from an additional 64 drill holes have been submitted for assay, with the remaining samples currently being cut and prepared.

About Midnight Sun

Midnight Sun is rapidly advancing the Solwezi Copper Project, with a focus on our flagship Dumbwa Target. 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 workforce, 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 our project and First Quantum’s Kansanshi Mine, Africa’s largest copper mining complex, approximately 6 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 Target hosts a robust 20-kilometre copper-in-soil anomaly, and ongoing drilling has demonstrated strong geological similarities to the nearby Lumwana deposit, underscoring its potential to host a significant copper system.

Led by an experienced geological team with a proven track record of major discoveries in the Zambia–Congo Copperbelt and globally, Midnight Sun’s goal is to delineate Zambia’s next generational copper deposit.
