 Victoria and Iris and the evaporation ponds at the Sur Viejo sector of the site. The areas currently being mined are located approximately 27 kilometers northeast of Nueva Victoria. Solar energy and electricity are the primary sources of power for this operation. The nitrate-rich salts are sent to Coya Sur, which is a processing plant located approximately 15 kilometers south of María Elena, and production activities undertaken there are associated with the production of potassium nitrate and finished products. The main production plants at this site include three potassium nitrate plants with a total capacity of 900,000 metric tons per year. There are also four production lines for crystallized nitrates, with a total capacity of 1,200,000 metric tons per year, and a prilling plant with a capacity of 360,000 metric tons per year. The potassium nitrate produced at Coya Sur is an intermediate product that is used as a raw material for the production of finished products (crystallized nitrates and prilled nitrates). Therefore, the production capacities listed above are not independent of one another and cannot be added together to obtain an overall total capacity. Natural gas is the main source of energy for the Coya Sur operation.
Pampa Blanca
The Pampa Blanca Project mine and facilities are located in the Antofagasta Region of northern Chile. It is located 100 kilometers northeast of the city of Antofagasta, in the commune of Sierra Gorda. The property has an area of 51,201 hectares and is composed of 152 mining concessions. The Pampa Blanca Project aims to produce salts rich in iodide, iodine and nitrate from the processing of caliche, extracted from deposits rich in this mineral. The Pampa Blanca Mining Plan considers an initial extraction of caliche at a rate of 5.5 million metric tons per year between 2024-2040. For the period 2024-2040 a total extraction of 85.3 million metric tons of caliche is projected with an average grade of 392 ppm of iodine and 5.4% of nitrates. The production process to obtain iodine as the main product, along with salts rich in sodium nitrate and potassium nitrate as by-products, consists of heap leaching with fresh water or with recirculated solutions to obtain a solution rich in iodate, which will then be treated in a chemical plant to transform it into elemental iodine in prill format.
