Midnight Sun Mining Corp. received notification from Rio Tinto Mining and Exploration Limited that the initial 2021 exploration campaign on Midnight Sun's Solwezi Licences has resumed after temporarily pausing at the end of June. This exploration work is being performed pursuant to the Earn-In and Joint Venture Agreement Exploration work to date has been focused on gaining a deeper geological understanding of the Solwezi Licences within the broader context of the various geological models hosting the significant copper mines in the area. Upon returning to the field, the exploration program is expected to include work at Dumbwa, Likoka and Mawemba. Dumbwa is a 20 kilometre copper-in-soil anomaly overlying basement rock where previous drilling encountered disseminated chalcopyrite and bornite with certain similarities to Barrick's Lumwana Mine, which is approximately 60 kilometres west of the Solwezi Licences. The best hole to date at Dumbwa was drilled by a previous operator and intercepted 1.24% Cu over 16 metres starting at a depth of 164 metres (SDRC-13). The planned program includes infill soils, air core drilling, reverse circulation drilling and diamond drilling to test possible mineralization in magnetic, radiometric, and induced polarization geophysical responses. Mawemba is a geophysical anomaly along the Mitu Trend which has returned positive geochemical and air core drill results similar to the original Mitu discovery area. Diamond drilling and an expanded soil survey are planned for the Mawemba target area. Diamond drill hole MDD-17-15 was initially drilled as a 3.7 kilometre step out from the discovery at Mitu, in the area now called Likoka, and measured 4.23% CuEq over 11.6 metres. The upcoming work will tighten geochemical spacing and increase air core drill coverage of the area in preparation for a diamond drill campaign.
