Midnight Sun Mining shifts to targeted drilling as Phase Two begins at Dumbwa

Midnight Sun Mining Corp (TSX-V:MMA, OTCQB:MDNGF) has begun a Phase Two exploration program at its Dumbwa copper deposit in Zambia, the company said, shifting from broad systematic drilling to a more targeted strategy aimed at expanding higher-grade mineralization.

The new phase builds on Phase One, which saw nearly 75,000 metres of drilling across the initial 11.5 kilometres of the roughly 20 kilometre Dumbwa copper-in-soil anomaly.

That work identified four areas of more intense copper mineralization within the broader corridor and generated an extensive geological, geochemical and geophysical dataset.

Phase Two will combine high-resolution ground magnetics, dipole-dipole induced polarization geophysics, soil geochemistry and diamond drilling, with two main objectives: extending the Dumbwa system northward and identifying higher-grade mineralization both within the previously drilled corridor and in potential satellite targets to the east and west.

An initial high-resolution ground magnetic survey over a previously drilled portion of Dumbwa identified distinct magnetic signatures associated with drill-confirmed copper mineralization, according to the company.

Similar signatures were also found outside the currently defined corridor, including two new exploration targets located around one kilometre east of the main trend.

Based on those results, the company is expanding the magnetic survey to cover the full 20 kilometre extent of the anomaly.

The company also plans to exte...
