Pampa Medina Drilling Continues to Validate Sedimentary-Hosted Copper Manto Model

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].
