Developing High-quality Copper Assets in Northern Chile
Marimaca is a TSX- and ASX-listed copper company developing high-quality copper assets in northern Chile. Its flagship asset, the Marimaca Oxide Deposit Project (MOD) in the Antofagasta region, is one of the few globally significant greenfield copper discoveries of the past decade. With close access to Antofagasta and the port of Mejillones, the MOD offers a low-risk development opportunity and substantial exploration upside.
Why Copper? Why Now?
Global demand for copper is booming. Demand is expected to increase from 28 million metric tonnes in 2025 to 42 million metric tonnes by 2040. Furthermore, the rapid growth of data centres to power AI is adding a significant new source of demand, with a single hyperscale AI data centre consuming up to 50,000 tonnes of copper.
Yet while demand accelerates, the industry faces a mounting supply challenge. Declining ore grades and a lack of major new discoveries are creating an ever-widening gap between copper demand and available supply. New sources of copper supply are desperately needed.
Marimaca Copper is focused on closing that gap.
Chile: a Tier 1 Mining Jurisdiction
Chile is consistently rated as one of the world’s premier mining jurisdictions and is the global leader in copper production. Marimaca’s land package is exceptionally located in the coastal belt at low elevation, close to Antofagasta and the port of Mejillones.
The prime location, combined with access to first-class infrastructure and utilities, supports the development of a high-margin copper project with relatively low capital intensity and reduced execution risk.
Our Three Core Value Pillars
Marimaca’s vision is to create significant value for shareholders and stakeholders through our three core pillars.
Marimaca Oxide Deposit: Near Term Production. The deposit is one of the few globally significant greenfield copper discoveries made in the last decade and represents a low-risk development opportunity, with substantial exploration upside. With the DFS complete and environmental approval received, we are advancing towards a final investment decision.
Pampa Medina: Game Changing Growth. The Pampa Medina Project is a near surface copper oxide deposit approximately 28km from the Marimaca Oxide Deposit. Recent drilling success at Pampa Medina has revealed exceptional results, demonstrating compelling district scale exploration with both copper oxide and sulphide potential.
Exploration: Complementary Opportunities. As a leading landholder in an emerging tier 1 discovery belt in Chile, Marimaca controls a portfolio of complementary exploration opportunities. This includes underexplored oxide targets in immediate proximity to the MOD and sulphide targets that remain largely untested.
