en.Wedoany.com Reported - The Antofagasta Regional Office of Chile's Environmental Assessment Service (SEA) has formally accepted the Environmental Impact Statement (DIA) for the "Chango 8 Mining Project" submitted by Collao Inversiones en Minería SpA.

The project plans to invest $2 million, with the goal of increasing the mineral delivery volume of the copper mine deposit named "Chango 8 Mining Project" from 5,000 tons per month to 25,000 tons per month. The project will maintain the existing open-pit mining method and crushing facilities. This production plan was initially approved by Sernageomin through Exempt Resolution No. 73/2022 dated March 2, 2022, and subsequently updated and confirmed by Exempt Resolution No. 545/2023 dated December 4, 2023, and Exempt Resolution No. 235/2025 dated July 2, 2025.

To achieve the production increase, the project's total monthly rock movement will reach 50,000 tons, of which 25,000 tons will be mineral and 25,000 tons will be waste rock. The extracted mineral will be transported to the surface and stockpiled in a stockyard area next to the crusher.

The crushed mineral will be screened and temporarily stockpiled, then transported using 28-ton capacity dump trucks to the Enami buyer located in the town of Taltal.
