(TSXV: MMA) (OTC Pink: MDNGF) (\"Midnight Sun\" or the \"Company\") is pleased to announce the mobilization of a third diamond drill rig to its flagship Dumbwa Target, a key component of the Company's Solwezi Project, located in the Domes Region of Zambia. The most recent drilling tender has been awarded to Chibuli Investments Limited, a local drilling contractor based in Ndola, Zambia. Under the terms of the contract, a minimum of 6,000 metres of core drilling will be completed with the newly added rig. This initial phase of drilling is focused on the southern 11.5 kilometres of the ~20-kilometre Dumbwa Target. \"The addition of a third rig allows us to fast-track our exploration efforts at Dumbwa\" stated Midnight Sun CEO Al Fabbro. \"This is an incredibly exciting phase for the Company, as we work to build upon our new geological model of the mineralization at Dumbwa. Our intensified drilling campaign reflects our structured approach and strong commitment to aggressive, but systematic, exploration. With drilling continuing to ramp up, we anticipate a consistent stream of results in the coming months.\"About Dumbwa:Dumbwa represents a near-surface, low-strip, bulk-tonnage exploration target with geology and mineralization closely resembling Barrick's Lumwana Mine, ~60 kilometres to the west. Dumbwa boasts a high-grade copper-in-soil anomaly extending ~20 kilometers along strike and more than 1 kilometer wide, with peak copper values reaching 0.73%. Previous drilling has confirmed sulphide copper mineralization, but additional drilling guided by structural controls is needed to better define the dip, continuity, size, and scale of the system. Multiple stacked mineralized horizons have been identified, which appear to be similar in deposition to those found at the Lumwana Mine.The recent dipole-dipole IP survey, covering the southern 11.5 kilometers of the strike extent, has revealed the structural framework of the Dumbwa target, critical for understanding its geometry. The interpreted IP results indicate a horizon that varies from relatively flat-lying and gently dipping, to areas with clear evidence of folding, ranging from open folds to very tight upright folds. There is a strong correlatio...
