Marimaca Signs Binding Option to Acquire the Madrugador Project, Further Consolidating the SdM Exploration District
News Release
Marimaca Signs Binding Option to Acquire the Madrugador Project, Further Consolidating
the SdM Exploration District
Vancouver, British Columbia, December 17, 2024 – Marimaca Copper Corp. (“Marimaca” or the “Company”)
(TSX: MARI) is pleased to announce the signing of a binding option agreement (the “Agreement”) to acquire the Madrugador
project (“Madrugador”). Details of the transaction are found below in the “Transaction Summary” section of this press release.
Madrugador consists of 10 mining concessions totaling 855 hectares and is located immediately adjacent to the Pampa Medina
project (“Pampa Medina”) (see press release dated October 8th, 2024). The acquisition of Madrugador and Pampa Medina
consolidates the Company’s ownership of the southern extent of the broader 14,500ha Sierra de Medina (“SdM”) property
package (see Figures 1, 2 and 3). Madrugador is located approximately 26km in distance and ~200m higher elevation relative
to the Company’s planned processing infrastructure as defined in the ongoing Marimaca Oxide Deposit (“ MOD”) Definitive
Feasibility Study (“DFS”) (see press release dated January 15th, 2024).
Madrugador hosts a historical National Instrument 43 -101 – Standards of Disclosure for Mineral Projects (“ NI 43-101”) non-
compliant resource estimate of copper hosted in dominantly oxide mineralization, which is detailed below in Table 1 alongside
relevant technical and regulatory disclosure. Marimaca is currently completing a review of available historical information to
plan and execute a validation and upgrade program of the historical resource.
Hayden Locke, President & CEO, commented:
“The acquisition of Madrugador consolidates our ownership of what we now recognize as a highly prospective district for
complementary leachable copper resources, underpinning our aspirations for growth in copper production in the future.”
”Similar to Pampa Medina, Madrugador hosts near or at surface, high grade, leachable copper mineralization. We believe these
assets already have the potential to add meaningful , compliant, resources and we are completing confirmatory reviews to
support eventual release of compliant Mineral Resource Estimates.”
”Both projects are also within areas where surface and geophysical exploration programs suggest good potential for extension
with ongoing exploration. Our VP Exploration, Sergio Rivera, and his team are drilling several targets now and we expect to step
up our exploration activities in the new year.”
”We are considering how the expanded project will fit in the broader development strategy of the MOD, as we expect the most
logical development strategy for these assets will be to utilise the future MOD infrastructure. This is especially true with respect
to our water management systems, potential pipeline routes, and the footprint of the SX-EW facility, to ensure an allowance for
future, modular, capacity expansions at low incremental capital cost.”
Table 1. Historic al Resource Estimate Taken From “Mineral Resources Technical Report on the Madrugador Property,
Antofagasta, Chile, Apoquindo Minerals, 2009” (the “Apoquindo Historical Estimate”)
The historical estimate uses CIM categories. The Qualified Person (QP) has not done sufficient work to classify the historical
estimate as a current resource at this stage. The Company is not treating the historical estimate as a current resource and
intends to verify and upgrade the historical estimate via a planned work program outlined in the “Validation Program”
section of this news release.

Property Overview
• 855ha land package adjacent to Pampa Medina and Marimaca’s broader SdM exploration property package
• Located in the eastern domain of the Antofagasta Region’s coastal copper belt, which hosts large, ‘Manto’-style copper
deposits including Capstone Copper’s Mantos Blancos mine and Antofagasta Minerals’ Cachorro project (Figure 4)
• Observable, shallow volcanic-hosted manto-style copper oxide mineralization near surface and in available drill core in the
western historical Madrugador Mine concessions, with copper oxide and mixed oxide-sulphide mineralization described in
historical reports and drilling observed in both volcanic and underlying sedimentary units in the east and southern
concessions (Figure 2 and Figure 3)
• Historical resources reported are located in the historical Madrugador mine area. Over 6,000m of drilling was completed in
the Brac area, however no historical resource was ever reported. Marimaca will review and consider the Brac drilling for
future mineral resource updates
• 45,885m of historical drilling data available for review and validation
• Complements the Pampa Medina project currently undergoing step out drilling by adding further potential for the
expansion of leachable copper resources
• Significant geological database to leverage for further exploration vectoring in the broader SdM land package
Validation Program (Underway)
• Geological relogging of available historical diamond drilling database
• Drill collar GPS validation, topography validation, survey validation
• Reinterpretation and rebuild of the geological model
• Strategy to upgrade historical resource to current resources will be further defined based on the results of the above
Transaction Summary
• Under the terms of the Agreement, Marimaca Copper will pay the following over an option term of 5-years to acquire
100% of Madrugador from Sociedad Legal Minera Juanita Uno del Mineral El Desesperado and Sociedad Legal Minera
Madrugador Uno del Mineral de Sierra Valenzuela. Marimaca may withdraw from the Agreement at any time subject to
forfeit of payments made up to the date of withdrawal.
― US$150,000 on signing
― US$250,000 on the first anniversary of signing
― US$400,000 24 months from of signing
― US$1,200,000 36 months from signing
― US$3,000,000 48 months from signing
― US$7,000,000 60 months from signing
• The sellers will retain a 1.5% royalty on Madrugador’s net gross sales. Marimaca will have the ability to buy back 1.0% of
the NSR for US$1,500,000 at any time and a right of first refusal on any sale of the royalty to a third party.
