Operational Continuity Integration Project

Description: The Environmental Impact Statement (DIA) of the Project "Operational Continuity Project Integration" (hereinafter the Project) of Minera Centinela (hereinafter Minera Centinela, the company or the owner), has the purpose of evaluating the execution of a Project that groups together different activities mainly associated with the operation of the oxide line and, to a lesser extent, the sulfide line. In particular, the Project considers the following scopes of which all, except the last one, are related to the oxide line: Exploitation of a new oxide slit, called the South Treasure, providing a new source of oxidized ore to the line of oxides. oxides Said exploitation includes the relocation of some facilities associated with the current operation, a new expit dump of the same name, an inpit dump to be enabled once the first phase of the pit has been exploited and a stockpile / temporary stock of ore. Redesign and exploitation of El Llano oxide sludge, originally approved according to the RCA N ° 356/2007 that favorably qualifies the project "Operational Continuity of Minera El Tesoro: Exploitation of Oxide Deposits of the Sierra Gorda District". To this end, an ore stockpile / stock is also considered. It is not considered an additional dump, since the ballast coming from this pit will be disposed in the dumps Treasure South, East and / or In Pit, depending on the case giving flexibility to the operation. Expansion of the area and extension of the mineral exploitation from the Mirador pit until the year 2022, with the consequent modification of the pit and the extension of the dump. Extension of the useful life of facilities, works and activities of the oxides line, without modifying the overall useful life of the Centinela Mining Integration project (RCA N ° 215/15) and without prejudice to the useful life already modified within the framework of the project Minera Centinela Development (RCA No. 436/16). Expansion of the Este Esperanza dump, allowing to optimize the transport distances of sterile extracted from the Esperanza pit and reduce the associated environmental impacts. However, as the scopes previously stated give account, the Project corresponds to a continuity of the current operation. Thus, it raises adjustments to the current operation that allow extending the useful life of the oxide line without increasing the processing rate or production over the environmentally evaluated. Objective The objective of the Project is to provide continuity and flexibility to the current operation of Minera Centinela, complementing the Centinela Mining Integration project through the exploitation of new sources of oxidized ore and the optimization of the exploitation of existing sources, without this implying the generation of new environmental impacts or of greater impacts than the current ones.
