Midnight Sun’s Dumbwa Copper Deposit Extends to 6.7 km of Continuous Mineralization - Adrian O’Brien

Midnight Sun Mining 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. 00:00 Intro 00:28 Dumbwa Discovery Update 01:15 Basement Dome Copper Explained 04:10 Majors-Style Drill Strategy 11:16 Data Modeling And MRE 12:33 Deposit Scale & Geometry 14:08 Share Price Disconnect 19:19 Kazhiba Oxide Monetization 20:32 Upcoming Catalysts Roadmap https://midnightsunmining.com/ TSXV:MMA OTCQX:MDNGF Press release discussed: https://midnightsunmining.com/2026/midnight-sun-continues-rapid-strike-expansion-at-dumbwa-now-6-7-kilometres-of-near-surface-copper-mineralization/ Sign up for our free newsletter and receive interview transcripts, stock profiles and investment ideas: http://eepurl.com/cHxJ39 Sponsor Midnight Sun Mining pays MSE a United States dollar ten thousand per month coverage fee.
