• Transformative Copper Discoveries in the Heart of Zambia

Midnight Sun is focussed on the exploration and discovery of world-class copper deposits in the heart of the prolific Zambia-Congo Copperbelt. Our vast 384² km Solwezi Project in Zambia represents multiple distinct opportunities for the discovery of transformative, multi-generational sulfide copper deposits and oxide copper mineralization that could potentially unlock significant near-term cashflow. We are surrounded by world-class operating mines and located adjacent to the largest copper mine in Zambia – First Quantum’s Kansanshi Mine. We have full control of all our assets, and are successfully exploring them, making new discoveries and advancing our top targets. And now, we are executing our plan to further explore the discoveries we’ve already made, systematically, across the extent of our property.

The Zambia-Congo copper belt is host to world-class copper deposits and some of the world’s richest mines. Many of the world’s leading mining companies are active in the region both as operators and explorers, including Barrick, Rio Tinto, Glencore, Ivanhoe Mines, First Quantum, and Anglo American.

Corporate Fact Sheet

Our 100% Owned Dumbwa Target

Dumbwa is a near surface, low-strip, sulphide copper opportunity with very similar geology and mineralisation to Barrick’s nearby Lumwana Mine. The target features a continuous high-grade copper-in-soil anomaly, which extends for over 20 km along strike and up to 2.67 km in width, with peak values of up to 0.73% copper. It is one of four key prospects that comprise our Solwezi Project.

Ideal targets in the Zambian Copper Belt, which have turned into mines, feature key characteristics including – a large coherent soil anomaly that is consistent with the ‘right geology’, bedrock exposure close to or at surface, and biological anomalies such as copper clearings. Dumbwa has all these criteria in abundance.

Along the 20 km long copper-in-soil anomaly at Dumbwa, previous drilling has demonstrated that it is directly tied to bedrock schist-hosted copper sulfide mineralisation, representing a very large high-grade copper exploration target and an incredible opportunity for Midnight Sun to make a transformative sulphide copper discovery.

Dumbwa has long been seen as an analog to Barrick’s 1.62 billion tonne, Lumwana mine.  Lumwana averages approximately 0.52% copper, is located just west of our property, and features nearly identical geology.1 Both Dumbwa and Lumwana are north-south trending, schist-hosted mineralised zones and both have multiple, stacked, mineralized horizons. But, by comparison, the geochemical anomaly at Dumbwa tends to have a higher copper tenor at surface and is laterally more extensive than found at Lumwana.

Our geological team is led by Dr. Kevin Bonel, the geologist responsible for leading the exploration team at Lumwana. We have the expertise of the person who led the team that transformed Barrick’s 900 million tonne deposit into a 1.62 billion tonne deposit in just 24 months, now driving our exploration at Dumbwa. Beyond Lumwana, Kevin has a career’s worth of experience in the belt, and several major discoveries to his credit. With Kevin at the helm of our geological team, we have the proven technical capability and depth to drive Dumbwa and our entire Solwezi Project forward.

Our Oxide Copper Opportunity1,2

Extensive oxide copper potential exists across our entire Solwezi Property package. We have focused on two initial key target areas featuring near-surface or at-surface high-grade oxide-copper mineralization: our Kazhiba and Mitu Targets.

At Kazhiba Main and Mitu, there may exist a unique and exciting near-term mining opportunity, that could produce significant near-term positive cash flow from our property.

Kazhiba Main

At Kazhiba Main, the company completed back-to-back programs in 2024 and 2025, which consisted of RC drilling, IP and Partial Ionic Leach Sampling. TM 

This work established “proof of concept” with regards to our oxide-copper plan. Kazhiba Main features a strongly variable, near-surface (low strip), unexploited,  oxide-copper opportunity.

Drill Highlights from the 2024 program include: 10.69% Cu over 21 metres, 5.60% Cu over 26 metres, and 3.01% Cu over 15 metres, and 4.66% Cu over 7 metres1, all near surface.

On January 20th 2026, the Company announced the completion of a maiden Mineral Resource Estimate for the near-surface Kazhiba Main Oxide Copper Deposit, located in Solwezi, Zambia.

The maiden Mineral Resource Estimate (“MRE”) consists of 2.33 million tonnes of Indicated mineral resources grading 1.41% copper (Cu) at a selected base case cut-off of 0.10 % Cu over all rock type categories. This initial MRE was prepared for the Company by DMT Kai Batla PTY Ltd. and has an effective date of January 20, 2026.

Previous programs also identified several new oxide copper anomalies that share a very similar geochemical signature to the known Kazhiba Main oxide copper deposit.  These new targets give us opportunity and room for growth.

Mitu

Drilling to date, intercepted numerous high-grade intervals of oxide mineralization, starting from surface.

Mineralization intercepted at Mitu, contained significant cobalt and nickel in addition to high grade copper.

Drill intercepts included 11.6 m of 3.44% Cu and 11.5 m of 1.41% Cu1

LEADERSHIP TEAM

A dedicated team of mineral exploration professionals, and geologists, with multiple discoveries and mines around the world to their credit.

RESPONSIBLE EXPLORATION

At Midnight Sun, we aim to better the communities in which we operate. We recognize that demand for responsibly mined critical metals such as copper play an integral role in electrification and a low-carbon world outlook.
