(“Marimaca Copper” or the “Company”) (TSX: MARI) is pleased to announce the results of the five drill hole diamond drilling exploration program from the eastern margin of the Marimaca Oxide Deposit (“MOD”). The program was designed to follow-up on the sulphide-bearing intersection of the previously released hole MAD-22, which intersected higher grades of primary copper mineralization down-dip of the Marimaca oxides. The program encountered challenging drilling conditions due to the orientation of the drilling from existing drill-pads along major known structures at the MOD. Results from this program and learnings regarding the approach for potential future deeper drilling, particularly origin and orientation, and will be considered for the design of follow-up exploration work. A discussion of results is provided in the “Geological Discussion” section of this news release. Highlights Four drill holes recovered to a maximum depth of 349m from surface, with three holes completed successfully to target depth The fourth hole, although recovered, MAD-25 was terminated above target depth due to poor rock quality caused by localized faulting Holes MAD-24, 25, 26 and 27 intersected the extension of the upper oxide and mixed/enriched copper mineralization This zone is interpreted as the near-surface, oxidized expressions of high-grade mineralized structures encountered in MAD-22 MAD-25 intersected 56m at 0.40% CuT from 136m including 24m at 0.63% CuT of secondary and primary sulphides in-line with the projected horizon from MAD-22, however, could not progress further into the horizon due to rock quality in a fault zone and was terminated at 218m Hole MAD-24 intersected 74m of 0.52% CuT from 24m including 18m at 0.68% CuT from 24m and 28m at 0.79% CuT from 64m above the projected sulphide horizon Hole MAD-24 intersected a barren post-mineral dyke from 224.3m which occupied the projected extension of the sulphide horizon from MAD-22 Hole MAD-27 intersected 40m at 0.50% CuT from 68m including 18m at 0.90% CuT of mixed and enriched mineralization from 74m, and a deeper intersection of 12m at 1.0% CuT of chalcopyrite mineralization from 162m Hole MAD-26 intersected strong magnetite alteration from 186m, however with a higher pyrite/chalcopyrite ratio rel...
