The Marimaca Project is located in the Antofagasta Region of northern Chile. It is situated within a 25 kilometre radius of plug-and-play infrastructure: people, power, clean water, road and rail networks.

The regional capital Antofagasta, a city built on mining and today the world’s “capital of copper” is only 60 kilometres away.

The Marimaca Project

Discovered, controlled and currently being explored by Coro, the Marimaca Project is demonstrating its potential to be one of the best new open-pittable copper oxide deposits discovered in Chile in recent times. A fully funded Phase II exploration program is currently underway, targeting an enlarged resource in the third quarter of 2019.


The initial discovery at Marimaca 1-23 was made by Sergio Rivera, Coro’s VP of Exploration. His hunch that this area had the potential to be a big project was confirmed only a few months later when a one-in-a hundred-year rainfall washed the Atacama dust away and revealed the green colored mountain side at Marimaca. Sergio and his experienced team are now advancing a second phase of exploration at Marimaca, with over 150 drill holes for approximately 50,000 metres.


Investors have the opportunity to generate considerable value during the early phases of the mining life cycle - namely the discovery, exploration and project definition stages. This is where Coro is with the Marimaca Project and with the discovery already made, the story is partly de-risked and a simple one focused on resource growth.
