Marimaca Copper Corp. (âMarimaca Copperâ or the âCompanyâ)Â (TSX: MARI) is pleased to announce the results from underground mapping and sampling at the Cindy Target (âCindyâ), which indicate broad zones of higher-grade mineralization. Highlights Underground channel sampling defines broad zones of higher-grade mineralization including: 38m @ 0.90% CuT, 112m @ 0.41% CuT, 36m @ 0.60% CuT, 48m @ 0.90% CuT and 160m @ 0.59% CuT Historical underground workings selectively exploited high grade copper mineralization in magnetite breccias Consists primarily of copper oxides atacamite, brochantite and chrysocolla with some wad Drilling commenced at the end of April targeting a 1,300m long complex with several magnetite breccias with the potential to host high grade copper mineralization
