Operation of Aggregates and RMI Poor Clares I and II and María and Helena

Description: The project that enters the SEIA through this DIA, consists of developing the activity of extraction and processing of aggregates from a surface of 316.3 hectares, on land part of mining properties of 1000 ha, owned by Sociedad de Inversiones La Tirana Limitada ; whose location is in the commune of Sierra Gorda, 25.5 kilometers northeast of the urban area of said commune, province of Antofagasta, Region of Antofagasta. A total exploitation of 6,326,000 m3 is estimated to be carried out in 3 consecutive stages of one year duration each, where an area of 184 will be exploited; 73.7 and 58.6 hectares respectively. The production process consists of; the extraction of the integral material from the surface by means of excavators; the transfer of material to the sorting plant where the physical process is carried out and the products are obtained; the collection of the products and finally the dispatch to the clients. Specifically, the extraction of arid sterile materials and RMI will be carried out. The materials that will be produced from the exploitation will be sand, gravel, gravel and filler materials. As currently on the ground, a project of the same productive nature is being developed, but of lesser importance, belonging to a limited Hidrocorp company; This will be included in this document for evaluation. This project consists of the extraction of 98,000 m3 from an area of 4.9 ha, so it did not require entering SEIA. Objective The objective of the project is to form a productive unit to extract and process integral sterile material that is in the mantle and with a depth of 2 m.
