 to such individually material properties is derived from the technical report summary (TRS) relating to such properties prepared in compliance with Item 601(b)(96) and subpart 1300 of Regulation S-K. Portions of the following information are based on assumptions, qualifications and procedures that are not fully described herein. Reference should be made to the full text of the TRS, incorporated herein by reference and made a part of this Form 20-F. The relevant TRS for the Salar de Atacama property, the Nueva Victoria property, the Pampa Blanca property and 
the Pampa Orcoma property, and the Mount Holland lithium project properties are included as Exhibits 96.1, 96.2, 96.3, 96.4 and 96.5, respectively, to this Form 20-F.
El Norte Grande Caliche, Chile
SQM's mining operations are concentrated in the First Region of Chile, where we mainly work in the mining areas of Tente en el Aire, Nueva Victoria Oeste, Hermosa and Torcaza, and in the Second Region of Chile, where we work in the mining area of Pampa Blanca.
The El Norte Grande Caliche, found in Regions I and II of northern Chile, corresponds to flat areas or “pampas”, that have been thoroughly explored. Results indicate that these prospects hold mineralization of nitrate and iodine. The area is accessible from Santiago through Route 5. The mineralization is stratiform in style, with a wide areal distribution, forming "spots" of several kilometers in extension, where mineralization thicknesses are variable. As a result of geological activity over time (volcanism, weathering, faulting) the deposits form continuous mantles. Environmental permits for mining operations, and the corresponding Environmental Qualification Resolution, grant access to the required water and electricity supply, as well as the infrastructure required for the mining operation.
Facilities
Nueva Victoria
The Nueva Victoria mine and facilities are located 140 kilometers southeast of Iquique and are accessible by highway. Since 2007, the Nueva Victoria mine includes the mining properties Soronal, Mapocho and Iris. At this site, SQM uses caliche ore to produce salts rich in nitrates and iodine, through heap leaching and the use of solar evaporation ponds. The main production facilities at this site include the operation centers for the heap leaching process, the iodide and iodine plants at Nueva
