ManagementMidnight Sun’s Dumbwa Copper Deposit More Than Doubles in Width to Over 2.4 km in Northern Block
Midnight Sun Mining reports drill results from its Dumbwa copper deposit in Zambia, where drilling has identified near-surface copper mineralization across an east-west extent exceeding 2,400 metres in the Northern Block, more than double the average width of the previously drilled corridor. The release reports 76 holes totalling 17,373 metres, including 0.47% Cu over 31.1 m (DBW-26-283), and says 70 holes remain pending because of assay lab delays.

AcquisitionMidnight Sun Initiates Phase Two Exploration Program at Dumbwa
Phase Two exploration has begun at the wholly-owned Dumbwa copper deposit in Zambia, combining high-resolution ground magnetics, dipole-dipole IP, soil geochemistry and targeted diamond drilling; an expanded magnetic survey will cover the full ~20 km copper-in-soil anomaly, ~19.1 line-km of additional IP at ~500 m spacing is underway, and ~4,600 soil samples are planned. Phase One, which included nearly 75,000 metres of drilling over the initial 11.5 km corridor, is expected to be completed by the end of Q3 2026. Midnight Sun also retained Rose & Company Holdings for investor relations for one year at US$50,000 per quarter, subject to TSX.V acceptance.
