Drilling At The Solwezi Licenses In Zambia

VANCOUVER - Midnight Sun Mining Corp. reported on preparations that have been completed and drilling has commenced on the Solwezi Licenses in Zambia. Four exploration targets and new concepts to be tested, with up to 4,500 meters of diamond drilling for up to 29 drill holes planned. The drill has arrived on site and set up at Mitu. This drill program was designed based on a review and re-interpretation of data generated by Rio Tinto Mining and Exploration Limited ("Rio Tinto") under the terms of a now terminated earn-in and joint venture agreement.

Al Fabbro, President and CEO, said, "Our Solwezi Licenses are located in an area of world-class copper mines and have so far shown many of the hallmarks of such deposits. We are of the view that this revised technical approach will provide the Company with an opportunity to catapult the project to a new level."

Midnight Sun has committed to up to 4,500 meters of drilling at its Solwezi Licences for the 2022 field season. The drill meterage has been allocated to 4 targets  which include the known Mitu and Dumbwa prospects and two new targets at North 22 Zone and the Crunch Zone.

The high-resolution airborne magnetics shows multiple structures cross cutting the Solwezi Dome margin and the overlying Copperbelt sediment succession. The displacement occurs primarily along northeast trending structures which are key to mineralization at the nearby Kansanshi Mine, owned by First Quantum Minerals. A reassessment of drill cores confirms a structural overprint on stratiform mineralization and provides justification to revisit existing prospects including the proposal of structural corridors controlling mineralization around the Mitu area as intercepted in hole MDD-17-15 which measured 4.23% CuEq over 11.6 meters. Five diamond drill holes have been planned for the Mitu area, targeting northeast-trending structures.

The Dumbwa Prospect is geologically located over basement rock, located approximately 60 kilometers west of Solwezi. The Dumbwa Prospect is marked by a north-south soil anomaly that extends for more than 20 kilometers. Previous drilling has intersected copper mineralization but follow up drilling was unable to determine the source of this large anomaly. New magnetic data shows that the southern area of the Dumbwa anomaly is underlain by a major lineament and two east-west drill hole traverses totaling nine holes have been planned to target the source of the surface anomaly.

The 22 Zone North & Crunch Zone targets are concepts derived from a combination of structural interpretation, subtle geochemical anomalism, and new insights into the genesis of mineralization in the Zambian-Congo Copperbelt. The primary objective of this drilling is to assess the structural control on mineralization in the area. The selected locations show apparent structural displacements of several hundreds of meters and are oriented in a favorable direction for fluid flow during compressional deformation, potentially leading to areas which trap and concentrate copper-bearing fluids.
