Midnight Sun’s Dumbwa Copper Deposit Extends to 6.7 km of Continuous Mineralization – Adrian O’Brien
Midnight Sun Mining (TSXV:MMA – OTCQX:MDNGF) VP Adrian O’Brien explains how the company has expanded its near-surface copper mineralization at the Dumbwa basement dome-hosted sulfide copper deposit in Zambia’s Domes region to 6.7 km strike within an 11.5 km phase-one program and a broader 20 km geochemical target. O’Brien explains the deposit’s close geological analogy to Barrick’s nearby Lumwana deposit, outlines a systematic “drill like a major” fence-drilling method with 50 m hole spacing and 100–200 m fence spacing enabled by low Zambian drill costs, and says the approach is designed to define edges, grade variability, and stacked, relatively flat mineralized lenses from surface to ~200 m depth. He discusses expectations for a first MRE in the fall, continued drill result releases, planned magnetics and metallurgical testing, reasons for share-price weakness despite operational progress, and ongoing but undisclosed monetization talks for the Kazhiba oxide resource.
