TSX - Toronto Stock Exchange · Copper · Canada · Drill Results

VANCOUVER, BC / ACCESS Newswire/ April 2, 2026 / Marimaca Copper Corp. ("Marimaca Copper" or the "Company") (TSX:MARI)(ASX:MC2)is pleased to report the complete silver assay results from its drilling to date at the Pampa Medina deposit, located at low altitude approximately 28km east of the Company's Marimaca Oxide Deposit ("MOD") (Figure 1), in Chile's prolific Antofagasta region. Copper assays and further details for holes reported in this announcement have been previously released.

Silver mineralization is present across the deposit, with elevated silver grades present in both oxide and sulphide copper-mineralized zones and broadly correlated with copper grade. The Company is releasing these silver assays alongside a consolidation of all Pampa Medina drilling results to date, highlighting the significance of the consistent, high-grade copper and silver mineralization across a 3km by 2km area of interest.

The Company has not yet completed its Phase I metallurgical programs at Pampa Medina and is therefore not reporting copper equivalent grades at this time. Silver by-products are common in Chilean manto-type deposits, including the nearby Mantos Blancos (Capstone Copper) and Cachorro (Antofagasta Minerals) deposits.

Highlights

-

Completion of the ICP assaying on all drilling completed to date at Pampa Medina indicates consistent, high-grade silver mineralization with the potential to be a predictable by-product credit at scale

Sergio Rivera, VP Exploration of Marimaca Copper, commented:

"Finalizing our silver assays across the complete Pampa Medina drilling database confirms our working hypothesis that silver grades would be elevated, consistent and strongly correlated with copper grades across the known deposit area to date. Drilling is ongoing on site, now combining 300m to 150m spaced delineation of the interpreted higher-grade zones of the deposit, as well as further step-out drilling focusing on extensions to the west, north-west and north-east. We intend to increase the rig count on site, currently at five, over the course of April and May in order to accelerate the 2026 drilling program. Pampa Medina continues to demonstrate qualities that make us very excited about the future of the deposit. Precious metal by-products in large primary copper deposits can surface exceptional value for builders and operators of these deposits as we have seen in recent and past transactions."

Overview of Pampa Medina

Pampa Medina is a manto-style copper deposit dominantly hosted in Jurassic-Triassic sedimentary units (sandstones, conglomerates, tuffs and black shales) overlain by andesitic volcanics and underlain by an Upper Paleozoic complex of metamorphosed sediments, volcanics and intrusions. Key lithological units are intruded by a dyke swarm and affected by post mineral normal faulting. Copper was originally identified in near-surface oxide mineralization dominated by atacamite, chrysocolla and both secondary chalcocite, and has now been identified in high-grade zones of bornite, chalcopyrite, covellite and chalcocite which extend at depth beyond the oxide-primary transition. Elevated silver grades are present in in both oxide and sulphide copper-mineralized zones and are generally correlated with copper grade.

Following Marimaca's consolidation of the project area and surrounding land packages in 2024, the Company reinterpreted all available geological information and developed an updated geological model for Pampa Medina, which identified the lower sedimentary units of interbedded sandstones, shales, tuffs and conglomerates as the priority target horizons for future drilling. Marimaca's 2026 drilling campaign will focus on three priority goals: definition of the high-grade sulphide-dominant central zone, delineation of the identified oxide extensions, and further step-out drilling to test potential extensions of the broader system identified in geophysical work completed to date.

Sampling and Assay Protocols

True widths are estimated as 80-90% of reported intervals, based on down-hole bedding and structural measurements. DDH holes were sampled on a 2m continuous basis, halved by a conventional core splitter on site with one half sent to the Andes Analytical Assay preparation laboratory in Copiapó and the pulps then sent to the same company laboratory in Santiago for assaying. Samples were prepared using the following standard protocol: drying; crushing all sample to -1/4" and passing through a secondary crusher to better than 80% passing -10#; homogenizing; splitting; pulverizing a 400-600g subsample to 95% passing -150#; and a 125g split of this sent for assaying. All samples were assayed for sequential copper %CuT (total copper); %CuS (acid soluble copper), %CuCN (cyanide soluble copper) and CuRes (residual copper), In addition to copper analyses, multi-element analysis including silver (Ag) was undertaken using ICP (multi-element Optical Inductively Coupled Plasma). A full QA/QC program, involving insertion of appropriate blanks, standards and duplicates was employed with acceptable results. Pulps and sample rejects are stored by Marimaca Copper for future reference.

Qualified Person / Competent Person

The technical information in this news release, including the information that relates to geology, drilling and mineralization was prepared under the supervision of, or has been reviewed by Sergio Rivera, Vice President of Exploration, Marimaca Copper Corp, a geologist with more than 40 years of experience and a member of the Colegio de Geólogos de Chile and of the Institute of Mining Engineers of Chile, and who is the Qualified Person for the purposes of NI 43-101 responsible for the design and execution of the drilling program.

The information in this announcement which relates to exploration results for the Pampa Medina Project is based on, and fairly reflects, information and supporting documentation prepared by Sergio Rivera, VP Exploration of Marimaca, a Competent Person who is a member of the Comision Minera (Chilean Mining Commission), Colegio de Geólogos de Chile and of the Institute of Mining Engineers of Chile.

About Marimaca Copper:

Marimaca is a TSX ("MARI") and ASX ("MC2")-listed copper company focused on the development of high-quality copper assets in northern Chile. The Company's flagship asset is the Marimaca Oxide Deposit Project ("MOD"), located in Chile's prolific Antofagasta region. It has the potential to produce 50kt per year starting within the next three years. It is one of the few globally significant greenfield copper discoveries made in the last decade and represents a low-risk development opportunity, given the proximity to the city of Antofagasta and port of Mejillones, with substantial exploration upside. The Company also controls additional exploration properties at Pampa Medina and Madrugador within the Sierra de Medina region, located 25 kilometers from the MOD, where recent drilling has identified both oxide extensions and high-grade sulphide mineralization at depth.

Forward Looking Statements

This news release includes certain "forward-looking statements" under (without limitation) applicable Canadian securities legislation, including, without limitation, statements regarding the development of activities at Pampa Medina, the potential growth of Pampa Medina, and the discovery's potential to complement the MOD. There can be no assurance that such statements will prove to be accurate, and actual results and future events could differ materially from those anticipated in such statements. Forward-looking statements reflect the beliefs, opinions and projections on the date the statements are made and are based upon a number of assumptions and estimates that, while considered reasonable by Marimaca Copper, are inherently subject to significant business, economic, competitive, political and social uncertainties and contingencies.

Such factors include, without limitation: risks that the development activities at Pampa Medina will not progress as anticipated, or at all, risks related to share price and market conditions, the inherent risks involved in the mining, exploration and development of mineral properties, the uncertainties involved in interpreting drilling results and other geological data, fluctuating metal prices, the possibility of project delays or cost overruns or unanticipated excessive operating costs and expenses, uncertainties related to the necessity of financing, uncertainties relating to regulatory procedure and timing for permitting submissions and reviews, the availability of and costs of financing needed in the future as well as those factors disclosed in the annual information form of the Company dated March 27, 2025 and other filings made by the Company with the Canadian securities regulatory authorities (which may be viewed at www.sedar.com).
