 electricity are the main sources of energy for this operation. The Pampa Blanca Project facilities also include operation centers for the heap leaching process, iodide plant, and evaporation ponds.
Pampa Orcoma
The Pampa Orcoma Project is located in the Tarapacá Region of northern Chile. It is situated 99 kilometers to the northeast of the city of Iquique, in the community of Huara. The property covers an area of 10,296 hectares and is composed of 45 mining concessions. The Pampa Orcoma Project aims to produce iodide, iodine and nitrate-rich salts from the processing of caliche that will be extracted from deposits rich in this mineral. The Pampa Orcoma Mining Plan considers an initial extraction of caliche at a rate of 8.4 million metric tons per year during the first four years of operation, followed by an 
extraction rate of 20 million metric tons per year from the fifth year of operation onwards. For the 16 year of LoM, a total extraction of 287.4 million metric tons of caliche is projected with an average grade of 408 ppm iodine and 6.7% nitrates. The production process to obtain iodine as the main product, along with salts rich in sodium nitrate and potassium nitrate as by-products, involves leaching with seawater or with recirculated solutions to obtain a solution rich in iodate, which will then be treated in chemical plants to transform it into elemental iodine in prill format. The Pampa Orcoma Project plan includes the construction of the following facilities: iodide and iodine production plants, with a capacity of 2,500 metric tons per year (of equivalent iodine), evaporation ponds to produce salts rich in nitrate at a rate of 320,325 metric tons per year and a seawater adduction pipe to meet the water needs. Solar energy and electricity are the primary sources of energy for this future operation. The development of the Pampa Orcoma Project was postponed, with no changes to the project information since December 31, 2022.
