MARIMACA COPPER CORP. Marimaca Copper Corp. announce results from channel sampling completed at the Mercedes target (?Mercedes?), located approximately 400m-1,000m north of the Marimaca Oxide Deposit (the ?MOD?). Chip sampling in 2m intervals was completed along new access road development which is currently being constructed in advance of planned exploration drilling in H2 2024.
The new sampling results expand the Mercedes area of interest eastward from the original discovery drilling in 2021, now extending approximately 700m x 500m x 100m depth (and remaining open) as indicated in the 2021 discovery drilling Based on the results of this work, the Company will proceed with plans to execute a follow-up drilling program at the expanded Mercedes AOI commencing in the second half of 2024. Results from the Mercedes sampling compare favourably to the original discovery channel sampling completed at the MOD. Mercedes has similar geological characteristics to the MOD and may represent the northern extension of the same IOCG-system.
Mercedes, like the MOD, is hosted in Jurassic intrusive stock and dyke-swarm rock types with mineralization controlled by a major NE sheeted structural system and associated fracture networks, cross-cut by a later series of WNW faults and dykes. Geological surface mapping at Mercedes has also confirmed the presence of NNE trending dacitic dykes, which have an important relationship with the highest grades of mineralization at the MOD. Copper mineralization identified at Mercedes is dominated by green oxides (atacamite/brochantite), chrysocolla and wad (black oxides).
Previously completed high-resolution MagDrone surveying at Mercedes demonstrates an anomaly similar in dimension and intensity to the MOD magnetic-inversion model, which coincides with the anomalous geochemical background sampling. While not expected to be incorporated into the Company?s ongoing Definitive Feasibility Study (?DFS?), the work completed at Mercedes continues to demonstrate opportunity for future oxide mine life extensions at the MOD. Next steps for Mercedes will be considered following the planned 2024 drilling program.
Highlights Samples were taken in 2m intervals across the newly developed road infrastructure Highlights from the channel sampling results at Mercedes include: 168m @ 0.26% CuT (incl. internal dilution) including: 36m at 0.44% CuT within a broader zone of 80m at 0.28% CuT; and 24m at 0.48% CuT within a broader zone of 46m at 0.39% CuT. 122m @ 0.20% CuT (incl.
internal dilution) including: 32m at 0.36% CuT within a broader zone of 56m at 0.27% CuT; and 24m at 0.25% CuT within a broader zone of 44m at 0.20% CuT. 12m at 0.50% CuT within a broader zone of 34m at 0.24% CuT Sampling direction is not considered optimal relative to the structural controls of mineralization given sampling was limited to the direction of new road development, which runs predominantly semi-parallel to the NE trending structures Drilling program will focus on testing directions near-perpendicular to key structures Results compare favourably to the original discovery channel sampling at the MOD ? which intersected 150m at 0.36% CuT.
