Our vast 384 km² Solwezi Project features numerous structural and mineralized targets and our team have made multiple significant discoveries on our property to date. We have identified 4 separate target areas which we believe to host unique geological systems, each with the potential for a significant copper discovery. The targets are our flagship Dumbwa Target, Mitu, Kazhiba (22 Zone) and Crunch Zone. At Dumbwa, we have made the first significant discovery in the belt in 22 years, identifying a vast copper system which could develop into a transformative sulphide copper deposit. At Kazhiba and Mitu, we are targeting both high-grade near-surface oxide-copper mineralization, as well as larger sulphide copper targets at depth.
Our Luswishi Dome Project is data-rich, and features 366 square kilometres of key geology, located approximately 40 kilometres southeast of the Company’s Solwezi Project.
Dumbwa
Dumbwa is our flagship target – a large-scale, near-surface sulphide, basement-dome hosted copper system, geologically analogous to Barrick Mining’s nearby Lumwana Mine.
The target is defined by a continuous, high-grade copper-in-soil anomaly extending over 20 km along strike and up to over 2 km in width, with peak values reaching 0.73% copper, highlighting its vast potential.
Drilling is actively underway and ongoing, with a focus on rapidly and systematically defining the scale of the system. Work completed to date has already outlined more than 5 km of strike, with tight drill spacing of 50 metres east to west and 100-200 metres north to south.
Our aggressive, yet phased and methodical approach is designed to efficiently build critical mass across the full 20 km system.
Dumbwa is one of four key prospects within our Solwezi Project, representing a cornerstone asset in our strategy to deliver a globally significant copper discovery.
Geologically, Dumbwa is closely analogous to Barrick Gold Corporation’s 1.6-billion-tonne Lumwana system, located immediately to the west. Both are basement-hosted, strain-controlled copper systems that are near-surface, north–south trending, and gently east-dipping, with mineralization hosted in laterally continuous schist units and developed across multiple stacked lenses.
Importantly, Dumbwa compares favourably on several key metrics. At Lumwana, mineralization typically averages 40–60 metres in thickness beneath 20–30 metres of overburden. At Dumbwa, mineralization commonly begins at surface and averages approximately 200 metres in thickness. In addition, Dumbwa’s surface geochemical signature shows higher copper tenor and extends over a significantly longer north–south strike.
“What initially struck me about the Dumbwa Target was the remarkable similarity to Lumwana. They are both north-south trending, schist-hosted mineralised zones and both have multiple, stacked, mineralized horizons. Previous drilling has demonstrated that the copper-in-soil anomaly at Dumbwa is directly tied to bedrock schist-hosted copper sulfide mineralisation. 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.” – Dr. Kevin Bonel, COO, Midnight Sun Mining
Kazhiba
The Kazhiba Target is part of the Company’s Solwezi Project, situated in the northwestern part of the property, approximately 6 kilometres west of First Quantum’s Kansanshi Mine. Kazhiba features both near-surface targets for oxide copper as well as larger sediment-hosted sulphide copper targets.
Kazhiba Main Oxide-Copper Deposit:
The primary target at Kazhiba, has been our Kazhiba Main Deposit, which the company carried out extensive work on over the course of 2024 and 2025, leading to the delivery of an initial MRE in January 2026. The Kazhiba Main Deposit represents an opportunity for potential near-term production and resulting cash-flow, which would provide a non-dilutive funding source for our larger sulphide copper targets including Dumbwa.
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.
Kazhiba Sulphide Copper Targets:
Kazhiba is underlain by a previously undiscovered basement dome similar to those at both Kansanshi and Solwezi. Domes are believed to be associated with the copper mineralization at nearby mines, including both First Quantum’s Kansanshi and Sentinel mines as well as Barrick’s Lumwana Mine.
Mineralization at Kazhiba was discovered by follow up shallow drilling in 2012 over a subtle copper anomaly with thick overburden. The discovery hole intersected 11.3 metres of 5.71% Copper, near surface. Additional intercepts include 21 metres of 3.26% Copper and 6.4 metres of 5.08% Copper.1 Drill campaigns in 2013 (reverse circulation) and 2014 (diamond drilling) extended the high grade, near surface discovery.
Kazhiba features several highly prospective sulphide copper target areas, which the company plans to explore in the future.
Mitu
Mitu is a target area located in the southwestern portion of our Solwezi Project. Early exploration at Mitu identified “ore shale” type mineralization on the flank of the Solwezi Dome, crosscut by Kansanshi style veins. A series of near surface Cu-Co-Ni-Au intercepts, identified and confirmed copper-cobalt mineralization, including an impressive drill intercept of 11.6 metres grading 3.44% Copper. Additional drill results included:
- MDD-16-01 – 8.0 m of 1.22% Cu, 0.09% Co, and 0.05% Ni and 14.0 m of 1.02% Cu, 0.03% Co, 0.06% Ni
- MDD-16-06 – 30.3 m of 0.49% Cu, 0.03% Co, and 0.05% Ni and 9.0 m of 0.49% Cu, 0.02% Co, 0.03% Ni
- MDD-16-09 – 9.4 m of 1.03% Cu, 0.14% Co, and 0.04% Ni
- MDD-16-11 – 28 m of 0.82% Cu, 0.03% Co, and 0.05% Ni
The discovery of structurally controlled Kansanshi-style mineralized veins represented an additional mineralizing event in the area and drilling delineated a 1 kilometre by 500 metre zone of mineralization which remains open. A VTEM survey carried out over the target delineated multiple conductive zones, all occurring in favourable geology, over more than 17 kilometres on strike.
Further results from drilling carried out in 2022 confirmed a new and exciting revelation, concluding that copper mineralisation intercepted at Mitu is associated with cobalt, nickel, and anomalous gold. This suite of metals is comparable in mineralization style and grade to that at First Quantum’s Sentinel Mine, located approximately 120 kilometres west of Midnight Sun’s Solwezi Project. This new discovery provides proof of concept and revealed more insight into the mineralisation at Mitu, strengthening our conviction that more than one multi-generational copper deposit may exist on our 384 square kilometre property, and this establishes a new analog for Mitu.
Mitu 2025 Exploration
At Mitu, an extensive Partial Ionic Leach sampling program will be launched to test the entire Mitu Trend along the western flank of the Solwezi Dome. Given the positive results generated using Partial Ionic Leach sampling at Kazhiba, the Company plans to collect approximately 1,800 samples for Partial Ionic Leach analysis along the entire Mitu target trend. Mitu has similar regolith to Kazhiba, which is generally unresponsive to traditional geochemical analysis, so Partial Ionic Leach is expected to more effectively identify and track further copper targets.
Oxide and sulphide copper mineralization has previously been identified at Mitu, and a Partial Ionic Leach sampling program covering all highly prospective geology was carried out in 2025, the results of which will drive a follow up IP surveying to finalize drill targets on each of the identified mineralized zones for follow up drilling.
Mineralization is associated with shale units which form chemical and physical “traps” for base metals at or near the favourable contact between the Upper and Lower Roan units. This contact zone along the western flank of the Solwezi Dome extends for over 17 kilometres on the Company’s License areas. Diamond drilling has confirmed the association of copper, cobalt, nickel, and gold with the carbonaceous shales, returning intercepts of up to 3.44% Copper over 11.4 metres. Further exploration work is required to delineate the geometry of the sub-basin to successfully target the prospective carbonaceous shale unit.
Extensive soil sampling and shallow drilling have also established extensive oxide copper potential at Mitu.
Crunch Zone
The Crunch Zone exploration target is situated between the Kazhiba Dome in the northwest and the Solwezi Dome in the southeast. This newly identified structural target features a wedged fan of tight structural folds, located between domal structures, and linked to Kansanshi via a succession of sedimentary host rock. A VTEM survey identified the largest untested continuous EM conductive target/anomaly on the property, and this trend occurs in the same stratigraphy as that surrounding the neighbouring Kansanshi Mine. The anomaly remains largely untested & continuous for over 5 kilometres in length and 2 kilometres on strike. The sheer size and scale demonstrated by this anomaly, clearly indicates that appropriate investigation and attention is warranted. This conductive trend represents a potential new discovery at the Crunch Zone.
Crunch in detail
Based on geophysical data, it appears a northeast trending wedge of Copperbelt strata is ‘crunched’ between the domes showing interference fold patterns that abruptly terminate against the domal structures. An analysis of a VTEM electromagnetic survey identified the largest untested continuous EM conductive target/anomaly on the property and suggests that mineralized fluids may have migrated along major faults or thrusts which occurred where the Copperbelt strata encountered the dome structures.
