Marimaca Copper Corp. has revealed significant drilling results from its Pampa Medina deposit, located approximately 28 kilometers east of its Marimaca Oxide Deposit in the Antofagasta Region of Chile. These results show a strong presence of ultra-high-grade copper and silver mineralization, including exceptional intersections that could greatly expand the deposit's known size and mineral resource potential.
The latest assays from the ongoing drilling program indicate notable continuity of copper-silver mineralization. Drilling hole SPRD-05 has intersected 96 meters of mineralization at 1.19% copper and 11.7 grams per ton silver, which includes a more concentrated section of 16 meters at 5.70% copper and 62.6 g/t silver. Further drilling has identified even higher grades, with a peak of 4 meters at 11.32% copper and 144 g/t silver.
The Pampa Medina deposit exhibits a manto-style structure primarily within Jurassic-Triassic sedimentary units, overlaid by andesitic volcanics. This geology supports the high concentration of bornite and chalcocite higher-grade sulphide mantos. The continuous high-grade mineralization across 150-meter drill spacings reinforces the deposit's extensive scope and underscores its potential as a significant project.
Marimaca Copper is engaged in a structured drilling campaign aimed at further delineating the area of interest (AOI) for a forthcoming Mineral Resource Estimate (MRE). As part of its strategy, the company will conduct geochemical and geophysical programs aimed at identifying new mineralized extensions across its Sierra Norte and Pampa Norte areas.
Sergio Rivera, Vice President of Exploration at Marimaca Copper, remarked on the drilling's results, highlighting their implications for a sizable mineral resource endowment in the central AOI. The ongoing drilling supports confidence in the long-term viability and economic potential of the Pampa Medina deposit.
Marimaca Copper has announced significant results from its ongoing drilling programme at the Pampa Medina deposit, with notable intersections of ultra-high-grade copper and silver. This includes a 16m interval of 5.70% Cu and 62.6 g/t Ag, highlighting the potential for substantial mineralisation.
The strong lateral continuity of high-grade mineralisation across the Pampa Medina deposit, as demonstrated by recent drill results, suggests a significant district-scale copper-silver system. This continuity is a promising factor for potential resource expansion and economic viability.
The identification of an ultra-high grade bornite zone is indicative of the deposit's quality and potential economic returns. Such high-grade intersections can positively influence future mineral resource estimates and project feasibility.
Marimaca Copper plans to complete a 150m-spaced drilling campaign to delineate the area of interest, followed by an initial mineral resource estimate. This phased approach aims to confirm and expand the known mineralisation while identifying new targets.
Located approximately 28km east of the Marimaca Oxide Deposit in the Antofagasta Region of Chile, Pampa Medina benefits from established mining infrastructure, which can facilitate efficient project development and reduce operational costs.
Marimaca Copper is conducting geochemical and geophysical surveys to identify additional mineralised zones and extensions beyond the current drilling. This proactive exploration could reveal new prospects and further enhance the project's value.
The company implements a strict QA/QC protocol involving meticulous sampling and laboratory assays conducted under professional supervision, ensuring high accuracy and reliability of the mineralisation data reported.
Given the promising drilling results and strategic exploration plans, Marimaca Copper's prospects appear positive. Continued high-grade discoveries could enhance investor confidence and potentially drive share value.
