About this episode
Bill Powers interviews Adrian O’Brien about the significant copper discovery at Dumbwa in Zambia.
MSE host Bill Powers interviews Midnight Sun Mining VP Adrian O’Brien for an update on the company’s Dumbwa copper discovery in Zambia’s Copperbelt. O’Brien shares how the company has now defined continuous copper mineralization over 5.3km of strike. He explains the release of assays from 99 drill holes after lab delays and QA/QC issues, saying results confirm continuity, scale, and a clear geological analog to Barrick’s neighboring Lumwana mine, with variable grades consistent with a bulk-tonnage system. He discusses the 20-km copper-in-soil anomaly, methodical fence-line drilling (four rigs, ~10,000 m/month, ~$160/m), expansion drilling to better discover and define the mineralization, and ongoing work toward completing the fully funded first 11 km of strike by end of Q3. The conversation also covers analyst reports, pending assays sent to Intertek, and plans to monetize the Kazhiba near-surface oxide resource (2.33 Mt at 1.41% Cu) to fund Dumbwa non-dilutively, plus general risk disclaimers about mining stocks. 00:00 Intro 00:49 Big Assay Release 02:35 Copperbelt Context 03:28 Market Reaction and Grade 08:06 Scale and Drill Plan 09:09 Funding and MRE Timing 10:25 Copper…
