Core Insights - Midnight Sun Mining Corp. has reported significant assay results from its drilling program at the Dumbwa Target in Zambia, demonstrating a mineralized strike length of over 3.6 kilometers [2][5][15] - The ongoing drilling program aims to further delineate the copper system, with a total of 122 holes completed and plans for an additional 140 holes to test the mineralized corridor [5][15] - The company emphasizes the geological similarities between the Dumbwa Target and the nearby Lumwana Mine, which supports the potential for a significant copper deposit [13][15] Drilling Results - The drilling program has yielded multiple intercepts of copper mineralization, with notable results including: - DBW-25-021: 0.89% Cu over 25 meters, with four separate mineralized zones [3] - DBW-25-030: 0.46% Cu over 50 meters, including 1.36% Cu over 6 meters [3] - DBW-25-027: 0.48% Cu over 21.85 meters [4] - The drilling results indicate consistent copper mineralization, reinforcing the company's confidence in the scale of the Dumbwa system [2][5] Future Plans - The company plans to conduct approximately 25,000 meters of drilling to further explore the mineralized corridor over the next 3 kilometers [5] - An additional 64 drill hole samples have been submitted for assay, with ongoing preparations for the remaining samples [5] Quality Control - The drilling was conducted using a conventional diamond drilling rig, with strict quality control measures in place, including sample handling and laboratory analysis by SGS Labs in Zambia [8]

Core Insights - Marimaca Copper Corp. has announced successful results from its 10,000m discovery drilling campaign at the Pampa Medina deposit, indicating significant extensions to high-grade copper mineralization and the commencement of a 30,000m follow-up drilling program [1][4]. Drilling Results - The discovery drilling program at Pampa Medina has defined a potentially significant new deposit, with notable intersections such as 48m of 2.05% Cu and 16m of 2.29% Cu from different drill holes [5][6]. - The southern drilling confirmed the primary mineralized sedimentary horizon extends 900m south of previous drilling, enhancing the continuity of mineralization [5][6]. - The drilling results have established a favorable mineralized stratigraphic sequence across a 1.6km x 1.4km area, with extensional drilling planned towards the north and west [5][6]. Geological Overview - Pampa Medina is characterized as a stratiform manto-style copper deposit hosted in Jurassic-Triassic sedimentary units, with copper mineralization identified in both near-surface oxides and deeper sulphide zones [6][7]. - The geological model has been updated to target lower sedimentary units, which are expected to be productive for future drilling campaigns [7]. Future Plans - The company has initiated a 30,000m Phase II drilling program with five rigs on site, aimed at further understanding the deposit's geological controls and extent [1][4]. - The exploration strategy includes geophysical surveys and additional drilling to explore potential extensions from the Pampa Medina deposit [68].
