---

Written by Amir Richani for Industrial Info Resources (Sugar Land, Texas)--Marimaca (Vancouver, Canada) anticipates producing 50,000 tons of copper cathode annually for 13 years at its Marimaca copper project in Antofagasta, Chile.

The company completed the feasibility study for the project. The company forecasted pre-production capital costs of US$587 million and a capital intensity cost of US$11,700 per ton of copper.

Following the announcement, Marimaca expects to obtain the necessary environmental approvals from the authorities before the end of this year and commence construction between the third and fourth quarters of 2026.

The mine will have a capacity of 50,000 tons of copper cathode for a mine life of 13 years, with an average annual production of 43,000 tons throughout the entire period.

The deposit has a proven and probable mineral reserve of 178.6 million tons, with an average grade of 0.42% CuT, representing 750,000 tons of contained copper based on measured and indicated resources.

In terms of water usage, the project has secured access to recycled seawater from the Bay of Mejillones, which will be connected through a pipeline. The company does not foresee the use of continental water or freshwater for its operations.
