Use of Adrianitas-Raúl Iron Minerals Stockpiles

Description: Use of Adrianitas-Raúl Iron Minerals Stockpiles Mining development projects over 5,000 tons / month The Project is located in the Atacama Region, Copiapó Province, north of the city of Copiapó, and consists of the exploitation, through recovery and processing of iron ores from three stockpiles located in the Adrianitas-Raúl Mine sectors. The above, in order to produce pre-concentrated iron minerals. Indeed, in the defined iron ore extraction area, there are three (existing) stockpiles, and the existence of 2.2 Mt of total resources and 1.8 Mt of extractable resources has been identified in them, which will allow a useful life of the Project of approximately 15 months, depending on the net production capacity. As said, the mineral is currently in the form of three stockpiles, and its exploitation will be carried out by recovering the mineral through front loaders, feeding a Mobile Benefit Plant (PBM), which through crushing, screening and magnetic concentration processes , will allow processing of the order of 120,000 tons of mineral per month, to produce of the order of 40,000 tons of pre-concentrate per month.As established in RCA001, the processing of minerals, from their exploitation to the production of pre-concentrate, will be carried out dry; In other words, the processes of this Project (for the processing of the mineral) do not need industrial water in any of its stages, since the concentration of the mineral is carried out by magnetic means and it only generates aggregates as mining waste, not generating tailings. The objective of the Project is to extract and process iron ores from existing stockpiles located in the Adrianitas-Raúl mine sectors, in order to take advantage of said resources for the production of iron pre-concentrate.
