Company Description
Midnight Sun Mining Corp. (MDNGF) is a junior exploration company in the gold ore mining and broader mining, quarrying, and oil and gas extraction sector. According to the company’s disclosures, Midnight Sun is focused on exploring its flagship Solwezi Project, located in Zambia, in the heart of the Zambia-Congo Copperbelt. This region is described as the second largest copper producing area in the world and the Solwezi property is characterized as vast and highly prospective.
The Solwezi Project is surrounded by producing copper mines, including what the company identifies as Africa’s largest copper mining complex, First Quantum Minerals’ Kansanshi Mine, situated next door to the project area. Midnight Sun states that it is led by an experienced geological team with multiple discoveries and mines around the world to their credit, and that its goal is to find and develop what it describes as Zambia’s next generational copper deposit.
Flagship Solwezi Project in Zambia
Midnight Sun’s public communications emphasize the strategic location of the Solwezi Project within the Zambia-Congo Copperbelt. The company highlights proximity to existing operations, including First Quantum’s Kansanshi Mine, and presents Solwezi as a highly prospective land package for copper-focused exploration. The project includes multiple targets, with Dumbwa and Kazhiba-Main featuring prominently in recent technical updates.
The company notes that work at Solwezi has included geochemical sampling, airborne VTEM surveys, reverse circulation (RC) drilling, diamond drilling, and a dipole-dipole induced polarization (IP) survey. These datasets are used to build geological and structural models that guide drill targeting along extensive copper-in-soil anomalies.
Dumbwa Target
The Dumbwa Target is described as Midnight Sun’s flagship focus within the Solwezi Project. Company releases characterize Dumbwa as a near-surface, low-strip, bulk-tonnage exploration target with geology and mineralization that closely resemble Barrick’s Lumwana Mine, located approximately 60 kilometres to the west. Dumbwa hosts a high-grade copper-in-soil anomaly extending roughly 20 kilometres along strike and more than 1 kilometre in width, with peak copper values reported at 0.73% in soils.
Midnight Sun reports that previous drilling at Dumbwa has confirmed sulphide copper mineralization. Multiple stacked mineralized horizons have been identified, which the company states appear similar in deposition to those at Lumwana. A 56 line-kilometre dipole-dipole IP survey over the southern 11.5 kilometres of the Dumbwa soil anomaly has been completed, and the interpretation of these IP results is used to refine drill targets. The IP work has revealed a target horizon that varies from relatively flat-lying and gently dipping to areas with open to very tight upright folds, and has highlighted major cross-cutting structures that help explain offsets between soil geochemistry and historical drilling.
Diamond drilling has been initiated and expanded at Dumbwa. The company reports that drilling is designed to confirm and correlate disseminated copper sulphide mineralization with the IP chargeability horizon and to test the extensive strike length of the target. Initial holes, such as DBW-25-003 and DBW-25-007, are described as confirming sulphide copper mineralization within near-vertical shear zones, with copper sulphides including bornite, chalcopyrite, and chalcocite occurring in disseminated form, within quartz blow-outs, in coarse sulphide clotting, and in healed fractures and veins.
Subsequent drilling at Dumbwa, including holes DBW-25-009 and DBW-25-010, has been used to test the east–west extent of mineralization and confirm the near-vertical dip of multiple parallel shear zones. The company reports that drilling has now established nearly 1.5 kilometres of mineralized strike at Dumbwa and continues to trace the mineralized corridor northward. Midnight Sun notes that it has expanded its geological team, increased core cutting and logging capacity, and deployed multiple diamond drill rigs at Dumbwa to accelerate exploration.
Kazhiba-Main and Kazhiba East Targets
Another key area within the Solwezi Project is the Kazhiba-Main oxide copper target. Midnight Sun reports that initial RC drilling at Kazhiba-Main yielded strong results and confirmed what it describes as a substantial high-grade, near-surface oxide copper blanket. Work to date has tested only part of the geochemical anomaly, and the company has initiated expansion drilling to establish the extents of mineralization and prepare an NI 43-101 compliant maiden resource estimate for Kazhiba-Main.
The company’s 2025 program at Kazhiba-Main includes a large RC drill grid designed to test expansion potential beyond previously drilled areas and to infill within the existing grid. Midnight Sun has also undertaken a due diligence diamond drilling campaign to re-drill selected intervals from earlier RC holes where “no sample return” was previously reported. The company explains that technical issues in wet soils led to misidentified cavities, and diamond re-drilling is being used to obtain complete profiles and verify mineralization. Early diamond results, such as those from hole MSZ-25-029E, are described as intercepting significant oxide copper mineralization within the existing footprint.
In addition, Midnight Sun has carried out a Partial Ionic Leach (PIL) geochemical sampling program over three Kazhiba East target areas. These areas are interpreted by the company as analogs to Kazhiba-Main in terms of copper mineralization and emplacement. The PIL sampling is intended to better delineate these targets and optimize future RC drill locations, with the goal of identifying additional near-surface oxide copper resources.
Exploration Approach and Technical Work
Midnight Sun’s disclosures emphasize a methodical, phased exploration strategy. At Dumbwa, the company combines soil geochemistry, VTEM geophysics, IP chargeability and resistivity data, and historical drilling to build a structural and geological model. This model is then used to position diamond drill holes along the interpreted mineralized horizon and across key structures. The company notes a strong correlation between IP chargeability highs, resistivity features, copper-in-soil anomalies, and mineralized intervals in drilling.
At Kazhiba-Main, the focus has been on defining a near-surface oxide copper zone through RC drilling, followed by diamond drilling for verification and resource definition. The company highlights the use of QA/QC programs that include insertion of blanks, duplicates, and certified reference materials, and describes sample preparation and analytical procedures at accredited laboratories in Kalulushi, Zambia and Ndola, Zambia.
Capital Markets and Listings
Midnight Sun Mining Corp. is listed on the TSX Venture Exchange under the symbol MMA, which the company identifies as its primary listing.

The company has stated that qualifying to trade on the OTCQX is intended to broaden its investor base and provide greater visibility and liquidity for U.S. shareholders.
Corporate Objectives
In its public statements, Midnight Sun consistently frames its objective as advancing the Solwezi Project, with an emphasis on Dumbwa and Kazhiba-Main, toward defining significant copper resources. The company refers to a Cooperative Exploration Plan with First Quantum Minerals in relation to work at Kazhiba-Main and notes that key steps in this plan, such as expansion drilling and a maiden resource estimate, are intended to create strategic options and potential near-term cash flow opportunities. Overall, Midnight Sun presents itself as a junior explorer focused on copper within a globally significant copper belt.
