## Resource

Midnight Sun Mining Corp Vice President of Business Development Adrian O’Brien joined Steve Darling from Proactive to provide an update on drilling results from the Dumbwa copper deposit at the company’s Solwezi Project in Zambia. The Dumbwa deposit is located in the prolific Domes Region, positioned near major producing operations including First Quantum Minerals’ Kansanshi mine and Barrick Gold’s Lumwana mine. O’Brien said drilling at Dumbwa has now exceeded 200 holes totaling more than 42,000 metres. Results received to date confirm near-surface copper sulphide mineralization extending across a continuous strike length of approximately 5.3 kilometres, with assays currently available for the first four kilometres of drilled strike. The ongoing discovery and delineation program continues with four drill rigs focused on expanding the deposit to the north along strike and extending known mineralization to the east and west. The Dumbwa system remains open to the north along the full extent of the copper-in-soil anomaly, open in several eastern areas, and open at depth. Management described Dumbwa as an exceptionally large, structurally controlled copper sulphide deposit with very shallow mineralization that could support low-strip, low-cost future development scenarios. Current drilling has primarily targeted the upper 220 metres of the system with the objective of defining a resource suitable for rapid development potential. The company also noted that similar mineralization styles at the nearby Lumwana project extend to depths well beyond 200 metres, highlighting potential for deeper expansion at Dumbwa. The mineralized corridor ranges from approximately 200 metres to more than 500 metres wide east-to-west. Copper grades vary across the deposit, ranging from broad lowe…
