Midnight Sun Mining Corp Reports Dumbwa Copper Deposit Drilling Results Midnight Sun Mining Corp. has reported results from drillholes completed on its wholly owned Dumbwa copper deposit, located in Solwezi, Zambia. Drilling has now surpassed 200 holes for a total of over 42,000 metres (“m”) and results to date confirm near surface copper sulphide mineralisation, over a continuous strike length of 5.3 kilometres, with assays received for the first ~4km of drilled strike. The initial discovery and delineation drill program continues with 4 rigs focussed on growing the deposit to the north along strike and to extend previously drilled mineralisation east and west. Quality control issues related to laboratory analysis have been resolved, and the related backlog of assays are now largely caught up. The Company’s drilling has now surpassed 200 holes for a total of more than 42,000m over 5.3km of strike, and continues to confirm that Dumbwa is an exceptionally large, very near surface, structurally controlled copper sulphide deposit which remains open for growth. Drill testing has focussed on the upper ~220m of the deposit with the intent of defining a resource amenable to rapid, low strip ratio, low-cost future development. It is noted that some areas of similar mineralisation at the nearby Lumwana project can be traced to vertical depths well beyond 200m. At Dumbwa, east-west width of the mineralised corridor ranges from 200m to greater than 500m. Copper grades are variable ranging from thick lower grade intercepts (> 50 m @ <0.3%) to thick higher-grade intercepts (>25m@>0.5%). Grade variability is pronounced along strike (north-south) and is influenced by cross-cutting northwest-southeast structures that adversely affect the strain regime and subsequent development of mineralised schists. In contrast, grades are relatively consistent east-west within the higher, medium and lower grade zones, and across the width of the mineralised corridor. Detailed lithological and structural logging is showing the Dumbwa copper deposit to be a stacked series of horizontal to shallow east dipping copper sulphide mineralised biotite and biotite-muscovite schists (“2 mica schists”) within a barren grey and pink basement gneiss sequence. The schists form in an intimate relationship with strain which has resulted in the schists being variably developed over the 5.3 km that have been drilled to date. Simply put, increasing strain leads to greater schist development, which in turn results in higher copper sulphide concentration. The relationship between high tectonic strain and the evolution of the copper-bearing schists is very clear, and the similarity between Lumwana and Dumbwa has been well established. Drilling was conducted using a conventional diamond drilling rig and drill core was captured for the entirety of each hole and placed into plastic core trays. All drill holes were cored in PQ until stable ground was achieved and then reduced to HQ size for the remainder of each hole. Sampling was based on visible copper mineralisation, and sample intervals honoured any important lithological boundaries. Core was then cut in house using a diamond saw and the right half of core was placed into a 200-micron plastic bag, assigned a unique sample number, and recorded into GeoSpark logging system. Samples always remained under the supervision of Midnight Sun staff to maintain chain of custody. All samples were then delivered to SGS Labs located in Kalulushi, Zambia, a fully accredited laboratory. Once received, the samples were sorted, dried, crushed, and pulverized (SGS code PRP90) followed by four-acid digest with ICP-OES finish (SGS Code ICP42S). Copper range of detection is 0.01-10%. Midnight Sun follows an in-house QA/QC program that consists of a random insertion every 10th sample of either a coarse blank, fine blank, coarse duplicate, fine duplicate, or Certified Reference Material (standards).

Midnight Sun Mining Corp. Reports Assay Results from 28 Holes, Totaling 5,247.30 Metres, from its 100% Owned Dumbwa Target, Located in Solwezi, Zambia Midnight Sun Mining Corp. reported assay results from 28 holes, totaling 5,247.30 metres ("m"), from its 100% owned Dumbwa Target, located in Solwezi, Zambia. Ongoing drilling continues to significantly extend the mineralized system at Dumbwa along strike. 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. お知らせ • Jan 20
Midnight Sun Mining Corp. Announces Resource Estimate for Kazhiba Main Copper Oxide Deposit Midnight Sun Mining Corp. 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. The effective date of the MRE is January 20, 2026. The MRE was completed by Dexter Ferreira, senior geostatistician, mining engineer and geologist, and a registered member of the South African Council of Natural Scientific Professionals. Mineral resources are reported using the 2014 CIM Definition Standards and were estimated using the 2019 CIM Best Practices Guidelines, as required National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101"). The MRE is undiluted and in situ, constrained by a localized digital terrain model using all drill hole collars in 3D space. Mr. Ferreira was responsible for the Kazhiba Copper Oxide Mineral Resource Estimate and has approved the scientific and technical information pertaining to the Mineral Resource Estimate in this news release. New Risk • Nov 06
New minor risk - Shareholder dilution The company's shareholders have been diluted in the past year. Increase in shares outstanding: 27% This is considered a minor risk. Shareholder dilution occurs when there is an increase in the number of shares on issue that is not proportionally distributed between all shareholders. Often due to the company raising equity capital or some options being converted into stock. All else being equal, if there are more shares outstanding then each existing share will be entitled to a lower proportion of the company's total earnings, thus reducing earnings per share (EPS). While dilution might not always result in lower EPS (like if the company is using the capital to fund an EPS accretive acquisition) in a lot cases it does, along with lower dividends per share and less voting power at shareholder meetings. Currently, the following risks have been identified for the company: Major Risks Earnings have declined by 27% per year over the past 5 years. Revenue is less than US$1m. Minor Risks Share price has been volatile over the past 3 months (17% average weekly change). Shareholders have been diluted in the past year (27% increase in shares outstanding).
