Midnight Sun Mining Corp (TSX-V:MMA, OTCQB:MDNGF) announced initial assay results, representing eight diamond drill holes, from the 2025 drilling campaign on the Kazhiba Main target at its flagship Solwezi Project in Zambia, which included 7.39% copper over 14.86 metres (m) from 17m to 31.86m depth in hole MSZ-25-029E.
The exploration company said drilling has intercepted new zones of “significant” oxide copper mineralization within the existing mineralized footprint.
"We are quickly and systematically marching Kazhiba toward a maiden resource, due before the end of the year," Midnight Sun Mining CEO Al Fabbro said in a statement.
"Kazhiba Main is an extraordinary, high-grade, near surface opportunity, and our team has taken all the right steps to properly define this unique, highly variable, oxide copper deposit."
Midnight Sun noted that the 2025 resource-edge definition campaign at Kazhiba-Main is now complete, with 163 holes drilled totalling 5,243m.
It added that assays for the 2025 reverse circulation (RC) program are pending and will be incorporated into a maiden NI 43-101 resource estimate that is expected to be completed in the fourth quarter of 2025.
As well, diamond drilling at Kazhiba Main is expected to continue through the end of November 2025, according to the company.
Midnight Sun Mining also announced that the Kazhiba East RC drilling program is now underway, which is designed to test three Partial Ionic Leach soil sample copper anomalies from the 2024 campaign and is planned to comprise a total of 100 RC drill holes.
The company said three Kazhiba East target areas have the same characteristics and geological profile as Kazhiba Main, thus representing expansion potential for more near-surface oxide resources at Kazhiba.
