Marimaca Copper Corp. announced the final reverse circulation (“RC”) drill results from the 2022 infill drilling campaign. Results reported in this release reflect 2,766m of drilling across 13 drill holes predominantly located in the northern portion of the Marimaca Oxide Deposit (“MOD”). The results include the best copper intersection drilled to date (LAR-109), on a grade-times-width basis, at the MOD, since it's discovery in 2016. Drilling was focused in the northern and central zones of the MOD, following up on the higher-grade green oxide centres identified in the previously reported 2022 infill drilling in the northern MOD. Drilling focused on the northern and central zones of the MOD – following up on previous 2022 infill results which identified high-grade green oxide zones in the northern MOD. The northern MOD was previously interpreted to be lower grade, dominantly WAD (black oxide) copper mineralization
Results expected to have positive implications for average grade in northern area of the deposit for the updated Mineral Resource Estimate (“MRE”) planned for the first half of 2023, targeting conversion of Inferred Resources into Measured and Indicated categories Highlights from reported results include LAR-109 intersected 308m at 0.94% CuT from 32m, including 186m at 1.37% CuT from 154m, including 26m at 4.83% CuT from 202m TAR-37 intersected 62m at 1.02% CuT from 2m, including 28m at 1.84% from 2m ATR-167 intersected 46m at 1.23% CuT from 180m within a broader intersection of 76m at 0.79% CuT from 150m TAR-40 intersected 68m at 0.30% CuT from 60m including 26m at 0.60% CuT from 90m The northern MOD continues to demonstrate potential for growth beyond the northeast limits of the 2022 MRE pit Results represent the final assays of the 2022 infill RC campaign 2,762m of diamond drilling (geological and geotechnical drilling) remains outstanding from the 2022 program with final assays pending Marimaca is finalizing plans for the H1 2023 exploration program which will follow-up on drill hole MAD-22, which intersected primary sulphides (dominantly chalcopyrite) down-dip of the MOD (92m at 2.11% CuT from 140m including 22m at 5.27% CuT).
