Marimaca Copper Corp. announced further results from the 2022 infill drilling campaign. Results reported in this release reflect 8,444m of drilling across 41 reverse circulation (“RC”) drill holes predominantly located in the northern portion of the Marimaca Oxide Deposit (“MOD”).

The results further improve confidence in the newly identified higher-grade centres located in the northern MOD which were intersected in previously reported drill holes from the 2022 campaign. Infill drilling continues to improve confidence in the higher-grade centers identified in the northern infill drilling announced on November 21st, 2022, and the higher-grade central MOD (MAR-175). Results continue to demonstrate potential for improved grade profile in the northern sector from previous grade interpolation of the northern MOD.

Target of the northern infill campaign is to improve the resource categorization from dominantly Inferred Resources (refere to technical report dated November 28, 2022) to Measured and Indicated categories for the purpose of future mine planning. Updated MRE remains on schedule for early 2023.
