Sociedad Química y Minera de Chile S.A. (SQM) operates as a producer of potassium nitrate, iodine, and lithium worldwide.
The company also produces specialty plant nutrients, iodine derivatives, lithium derivatives, potassium chloride, potassium sulfate and certain industrial chemicals (including industrial nitrates and solar salts). The company’s products are sold in over 100 countries through its worldwide distribution network, with 96% of the company’s sales in 2024 derived from countries outside Chile.
The company’s products are mainly derived from mineral deposits found in northern Chile. The company mines and processes caliche ore and brine deposits.
From the company’s caliche ore deposits, the company produces a wide range of nitrate-based products used for specialty plant nutrients and industrial applications, as well as iodine and iodine derivatives. At the Salar de Atacama, the company extracts brines rich in potassium, lithium, sulfate and boron in order to produce potassium chloride, potassium sulfate, lithium solutions and bischofite (magnesium chloride). The company produces lithium carbonate and lithium hydroxide at the company’s plant near the city of Antofagasta, Chile, from the solutions brought from the Salar de Atacama. The company markets all of these products through an established worldwide distribution network.
The company’s products are divided into six categories: specialty plant nutrients; iodine and its derivatives; lithium and its derivatives; potassium chloride and potassium sulfate; industrial chemicals and other commodity fertilizers.
Specialty plant nutrients are premium fertilizers that enable farmers to improve yields and the quality of certain crops. The company’s main specialty fertilizer is potassium nitrate, which is used primarily via fertigation in high-value crops. Iodine and iodine derivatives are used in a wide range of medical, agricultural, and industrial applications, as well as in human and animal nutrition products. They are mainly used in the X-ray contrast media, polarizing film and pharmaceuticals. Lithium and its derivatives are mainly used in batteries, greases and frits for production of ceramics. Potassium chloride is a commodity fertilizer that is produced and sold by the company worldwide. Industrial chemicals have a wide range of applications in certain chemical processes such as the manufacturing of glass, explosives and ceramics. Industrial nitrates are also being used in concentrated solar power plants as a means for energy storage. Additionally, the company trades other complementary fertilizers worldwide to diversify its offerings.
Specialty Plant Nutrition: The company offers three main types of specialty plant nutrients for fertigation, direct soil, and foliar applications: potassium nitrate, sodium nitrate, and specialty blends. The company also sells other specialty fertilizers, including third-party products. These products, available in solid or liquid forms, are mainly used on high-value crops like fruit, flowers, and some vegetables. They are widely utilized in modern agricultural techniques, such as hydroponics, greenhouses, and fertigation (where fertilizer is dissolved in water before irrigation).
Specialty plant nutrients offer advantages over commodity fertilizers, such as quick absorption, excellent water solubility, and low chloride content. Potassium nitrate, a key product, comes in crystalline and prill forms for various applications. Crystalline potassium nitrate suits fertigation and foliar use, while prills are ideal for direct soil application.
The company markets its products under the following brands: Ultrasol (fertigation), Qrop (soil application), Speedfol (foliar application), and Allganic (organic agriculture).
Sophisticated customers now seek integrated solutions rather than single products. The company’s offerings include customized blends and agronomic services, enhancing plant nutrition for better yields and quality. Derived from natural nitrate compounds or potassium brines, its products feature beneficial trace elements, offering advantages over synthetic fertilizers. Consequently, specialty nutrients command a premium price compared to standard fertilizers.
Iodine and its Derivatives: The company is the world’s leading producer of iodine and iodine derivatives, which are used in a wide range of medical, pharmaceutical, agricultural and industrial applications, including X-ray contrast media, polarizing films for LCD and LED, antiseptics, biocides and disinfectants, in the synthesis of pharmaceuticals, electronics, pigments and dye components.
Lithium and its Derivatives: The company is a leading producer of lithium carbonate, which is used in a variety of applications, including electrochemical materials for batteries used in electric vehicles, portable computers, tablets, cellular telephones and electronic apparatus, frits for the ceramic and enamel industries, heat-resistant glass (ceramic glass), air conditioning chemicals, continuous casting powder for steel extrusion, pharmaceuticals and lithium derivatives. The company is also a leading supplier of lithium hydroxide, which is primarily used as an input for the lubricating greases industry and for cathodes for high energy capacity batteries.
Potassium: Potassium chloride is produced from brines extracted from the Salar de Atacama. This commodity fertilizer is used to nourish various crops, including corn, rice, sugarcane, soybeans, and wheat.
Industrial Chemicals: The company produces and sells three industrial chemicals: sodium nitrate, potassium nitrate and potassium chloride. Sodium nitrate is used primarily in the production of glass, explosives, and metal treatment, metal recycling and the production of insulation materials, among other uses. Potassium nitrate is used in the manufacturing of specialty glass, and it is also an important raw material for the production of frits for the ceramics, enamel industries, metal treatment and pyrotechnics. Solar salts, a combination of potassium nitrate and sodium nitrate, are used as a thermal storage medium in concentrated solar power plants. Potassium chloride is a basic chemical used to produce potassium hydroxide, and it is also used as an additive in oil drilling, as well as in food processing, among other uses.
Other Products and Services: The company sells a variety of fertilizers and blends, including those it does not produce. The company is the largest producer of potassium nitrate and distributor of potassium nitrate, sulfate, and chloride.

Some of these activities are being directly carried out by the company’s internal geological exploration team, based in the company’s office in Perth, Western Australia, with others being worked in conjunction with partners through earn-in agreements. Activities range from desktop target generation to on-site mapping, rock chip/soil sampling and drilling.
During 2024, the company also expanded into early exploration projects in Sweden, subject to conditions precedent, and Namibia, with similar activities as the ones being carried out in Australia.
In Chile, the company is actively conducting exploration for metallic minerals in the mining properties the company owns. If such minerals are found, the company may decide to exploit, sell or enter into an association to extract these resources. The company’s exploration efforts are focused on the layer of bedrock that lies beneath the caliche ore that the company uses as the primary raw material in the production of iodine and nitrates. This bedrock has significant potential for metallic mineralization, particularly copper, gold and silver. A significant portion of the company’s mining properties are located in the Antofagasta region of Chile, where many large copper producers operate.
The company has an in-house geological exploration team that explores the area directly, identifying drilling targets and assessing new prospects. In 2021, the team has confirmed the existence of high-grade copper and gold mineralization at the Bufalo project, located 120 kilometers east of the city of Antofagasta. The Bufalo project corresponds to a district that hosts several mineralized bodies of copper, copper-gold and copper-gold-silver in which SQM has already drilled nearly 170,000 meters, using the company’s own diamond and reverse circulation RC drilling machines. More than 45 projects with copper potential have also been generated, in greenfield and intermediate exploration stages, which are under study and drilling. The company also has a metal business development team that works to engage partners interested in investing in metal exploration within the company’s mining properties. As of December 2024, the company had an option agreement in place with a private equity-owned mining company. It participated in the formation of a joint venture as a result of the exercise of an option agreement with a major mining company in the precious metals market.
Main Business Lines
Specialty Plant Nutrition
The company is the world’s largest producer of potassium nitrate.
Specialty Plant Nutrition: Market
Specialty plant nutrients serve various agricultural purposes, including fertigation for high-value crops like vegetables and fruits. These fertilizers must be highly soluble and free of impurities for modern irrigation methods, such as drip and micro-sprinkler systems. Potassium nitrate stands out among these nutrients due to its chlorine-free composition, high solubility, proper pH, and lack of impurities, allowing it to command a premium price over alternatives like potassium chloride and sulfate.
Modern irrigation systems are widely used in protected crops and high-value fruit plantations like greenhouses, tunnels (for berries), and shade houses (for tomatoes). Specialty nutrients are also applied for foliar and granular soil applications in niches, such as potato and tobacco production.
Specialty plant nutrients have distinct characteristics that can increase productivity and improve quality when applied to specific crops and soils. These products offer certain benefits over commodity fertilizers derived from other sources of nitrogen and potassium, such as urea and potassium chloride.
Specialty Plant Nutrition: The company’s Products
The company produces three main types of specialty plant nutrients that provide nutritional solutions for fertigation, direct soil applications, and foliar fertilizers: potassium nitrate (KNO3), sodium nitrate (NaNO3), and specialty blends.

The company has established capabilities in commercial management, supply, flexibility, and inventory management, enabling it to respond to the evolving fertilizer market and secure profits from these transactions.
Production Process
The company’s integrated production process can be classified according to its natural resources: caliche ore deposits, which contain nitrates, iodine and potassium; brines from the Salar de Atacama, which contain potassium, lithium, sulfate, boron and magnesium; and spodumene deposits from the Mt. Holland project in Western Australia, which contain lithium.
Caliche Ore Deposits
Caliche ore deposits are located in the First and Second Regions in northern Chile. During 2024, the company’s mining operations were concentrated in the First Region where it mainly worked in the mining sectors Tente en el Aire, Mina Oeste, Hermosa, Mina Sur and Torcaza, and in the Second Region at the Pampa Blanca site. Operations at the El Toco mine (which is part of the Maria Elena site) and the Pedro de Valdivia site were suspended in November 2013 and November 2015, respectively, in an effort to optimize its production facilities with lower production costs.
During 2024, SQM used four continuous mining equipment systems to replace the drilling and blasting process for mining some of the caliche ore and obtaining a smaller ore size (under 6 ½ inches) that allows a better metallurgical recovery.
The run of mine ore is loaded in heaps and leached with water to produce concentrated solutions containing iodine, nitrate and potassium. These solutions are treated at the company’s iodide plants where iodine is extracted through both solvent-extraction and blow out processes. The remaining solutions, which are rich in nitrates and potassium, are subsequently sent to solar evaporation ponds where the solutions are evaporated and after iodide is obtained, nitrate and potassium salts are produced. These concentrated salts are then sent to Coya Sur where they are used to produce potassium nitrate and sodium nitrate.
Caliche Ore-Derived Products
Caliche ore-derived products are sodium nitrate, potassium nitrate, sodium potassium nitrate and iodine.
Sodium Nitrate
During 2024, sodium nitrate for both agricultural and industrial applications was produced from nitrate salts from the company's mining operations at Sur Viejo and fed to its new crystallization plant located in Coya Sur. Crystallized sodium nitrate is processed at the Coya Sur production plants to produce sodium nitrate and sodium potassium nitrate in different chemical and physical forms, including crystallized and prilled products. Finally, the products are transported by truck to the company's port facilities in Tocopilla for shipping to customers and distributors worldwide.
Potassium Nitrate
Potassium nitrate is produced at the company's Coya Sur facility using a production process developed in-house. Potassium salts produced at Nueva Victoria or Coya Sur, as well as potassium salts from the Salar de Atacama, are added to the company's conversion plants. A chemical reaction begins, transforming sodium nitrate into potassium nitrate and creating formed sodium chloride as a by-product. Depending on the specifications of the required product, it is subjected to an adiabatic or atmospheric cooling process to obtain the required quality.
The company’s potassium nitrate production capacity at Coya Sur is approximately 900,000 metric tons per year.
The potassium nitrate produced at Coya Sur is transported to Tocopilla for shipping and delivery to customers and distributors. All potassium nitrate produced in crystallized or prilled form at Coya Sur has been certified by TÜV-Rheinland under the quality standard ISO 9001:2015. Additionally, the Coya Sur and Nueva Victoria leaching sites achieved certification by TÜV-Rheinland in 2023 under the ISO 50001:2015 quality standard (certification of energy management systems), and in Coya Sur, the company is advancing in the phase two of the external audit to certify its potassium nitrate, sodium nitrates and soluble fertilizers production.
Iodine and Iodine Derivatives
During 2024, the company produced iodine at its facilities at Nueva Victoria, Pedro de Valdivia and Pampa Blanca (iodide solutions). Iodine is extracted from solutions produced by leaching caliche ore.
As in the case of nitrates, the process of extracting iodine from the caliche ore is well established, but variations in the iodine and other chemical contents of the treated ore and other operating parameters require a high level of know-how to manage the process effectively and efficiently.
The company has obtained patents in the United States and Chile (Chilean patent number 47,080) for its iodine prilling process.
Prilled iodine is tested for quality control purposes, using international standard procedures. It is then packed in 20 to 50-kilogram drums or 350-to-700-kilogram maxi bags and transported by truck to Antofagasta, Mejillones, or Iquique for export. The company’s iodine and iodine derivatives production facilities have been certified by TÜV-Rheinland under the ISO 9001:2015 program, providing third-party certification of its quality management system. The last recertification process was approved in November 2022, valid through March 2026.
The company's total iodine production in 2024 was 13,101 metric tons, predominantly from its Nueva Victoria facility. The company has the flexibility to adjust its production according to market conditions.
The company uses a portion of the iodine it produces to manufacture inorganic iodine derivatives, which are intermediate products used for manufacturing agricultural and nutritional applications, at facilities located near Santiago, Chile. The company also produces inorganic and organic iodine derivative products together with Ajay, which purchases iodine from the company. In the past, the company has primarily sold its iodine derivative products in South America, Africa and Asia, while Ajay and its affiliates have primarily sold their iodine derivative products in North America and Europe.
Salar de Atacama Brine Deposits
The Salar de Atacama, located approximately 210 kilometers east of Antofagasta, is a salt-encrusted depression in the Atacama Desert, within which lies an underground deposit of brines contained in porous sodium chloride rock fed by an underground inflow from the Andes mountains, which is the result of millions of years of climatic and tectonic impacts. Brines are pumped from depths of 15 to 150 meters below the surface, through a field of wells that are located in the Salar de Atacama, distributed in areas authorized for exploitation, and which contain relatively high concentrations of potassium, lithium, sulfates and other minerals.
The company’s mining exploitation rights to the Salar de Atacama are pursuant to the Corfo Agreements, which expire in 2030.
For the year ended December 31, 2024, revenues related to products originating from the Salar de Atacama represented 55% of its consolidated revenues, consisting of revenues from its potassium business line and its lithium and derivatives business line for the period. All of the company’s products originating from the Salar de Atacama are derived from its extraction operations under the SQM-Corfo Agreements. As of December 31, 2024, only six years remain on the term of the SQM-Corfo Agreements.
Under the Chilean National Lithium Strategy announced in April 2023, the Chilean government, through Codelco, intends to participate in the lithium-related activities in the Salar de Atacama. On December 27, 2023, SQM and Codelco signed a non-binding MOU, which, among other matters, established a framework for the terms and conditions of the definitive agreements for a new entity through which SQM’s subsidiary, SQM Salar, may continue to exploit mineral resources in the Salar de Atacama until 2060. Corfo has granted to Codelco’s subsidiary, Minera Tarar, the rights to exploit the Salar de Atacama from 2031 to 2060, which will be contributed to the joint venture. If the parties are unable to agree on definitive agreements for the proposed new entity, either the Chilean government or SQM could allow the SQM-Corfo Agreements to expire in 2030 in accordance with their terms.
Products Derived from the Salar de Atacama Brines
The variety of products that may be derived from the Salar de Atacama brines includes solutions of lithium chloride, lithium sulfate, lithium carbonate, lithium hydroxide, lithium salts, potassium chloride, potassium salts, potassium sulfate, boric acid, sodium chloride and bischofite (magnesium chloride).
In order to produce these products, brines from the Salar de Atacama are pumped to solar evaporation ponds. Evaporation of the water contained in the brine in a sequential process of precipitation and evaporation, results in potassium-enriched salts and lithium-concentrated brines. In the first stages of the evaporation process, sodium chloride salts (halite) precipitate followed by potassium chloride salts together with sodium chloride (sylvinite), which are used to produce fertilizer products. The brine that remains in the evaporation pond system continues its concentration, producing additional products of interest, such as lithium sulfate salts and a concentrated lithium chloride solution, which are used to produce lithium sulfate concentrate and lithium carbonate, respectively.
Lithium Chloride Solution and Lithium Carbonate
The production capacity of the company’s lithium carbonate facility at the end of 2024 was 210,000 metric tons per year.
The company’s lithium carbonate production quality assurance program has been certified by TÜV-Rheinland under ISO 9001:2015 since September 2018.
Lithium Hydroxide (from Lithium Carbonate)
The company has three lithium hydroxide plants in Chile, one of which has two production lines, and the second of which came into operation at the end of July 2024. Together, they have a total production capacity of 40,000 metric tons per year. These plants are located at the lithium production chemical plant, adjacent to the company's lithium carbonate operations.
The company’s lithium hydroxide production quality assurance program has been certified by TÜV-Rheinland under ISO 9001:2015 since September 2018.
Lithium Sulfate
During the brine concentration process and if the chemistries are favorable, it is possible to obtain lithium sulfate as additional raw material. This salt mainly precipitates in the potassium carnallite and bischofite stages.
After collection, the lithium sulfate is treated in the MOP H II plant through crushing, flotation and filtration processes, obtaining wet lithium sulfate as an intermediate product. In addition, salts with high potassium content are obtained as a by-product of the process, which are treated in the adjacent SOP-H plant, allowing additional potassium chloride to be obtained.
The wet lithium sulfate is then treated at the SOP S/C plant producing dry lithium sulfate as a finished product, which is sent to its refining plant and different tolling facilities in China to be converted into lithium hydroxide and/or lithium carbonate.
Lithium Hydroxide (from Lithium Sulfate)
The company’s lithium hydroxide operations in China began at the beginning of 2023, with a design annual capacity of 20,000 metric tons. The production of lithium hydroxide monohydrate from lithium sulfate begins with a purification stage of the raw material for its subsequent transformation to lithium carbonate, which is subsequently converted into high-purity lithium hydroxide through crystallization, drying, cooling and packaging stages. Impurities from the process are eliminated in a form of mixed salts, avoiding liquid waste in the plant. Sodium sulfate is generated as a by-product, which is dried and packaged for sale.
Additionally, the company has tolling contracts with tolling facilities in China for the refining of lithium sulfate with an additional annual capacity of 20,000 metric tons allowing the production of lithium hydroxide and/or lithium carbonate.
Potassium Chloride
The company uses potassium chloride derived from the Salar de Atacama brines in the production of potassium nitrate. Production of its own supplies of potassium chloride provides the company with substantial raw material cost savings. The company also sells potassium chloride to third parties, primarily as a commodity fertilizer.
To produce potassium chloride, brines from the Salar de Atacama are sent to the first evaporation stage, where sodium chloride salts (halite) precipitate, are then harvested and removed. These salts have the potential to be used in the copper mining process. In the second stage of the evaporation process, the remaining brine from the first stage is transferred to other evaporation ponds where potassium chloride salts together with sodium chloride (sylvinite) precipitate. These salts are harvested and then sent for treatment at one of the wet potassium chloride plants where potassium chloride is separated by a grinding, flotation, and filtering process. In the final evaporation stage, salts containing magnesium are harvested and treated at one of the cold leach plants where magnesium is removed. Part of the potassium chloride is transported approximately 300 kilometers to the company’s Coya Sur facilities via a dedicated truck transport system, where it is used in the production of potassium nitrate. The use of potassium chloride salts as a raw material in Coya Sur allows the company to capture significant savings, as it allows the company to use potassium salts with different qualities and to avoid buying and importing potassium chloride from external sources.
The remainder of the potassium chloride produced at the Salar de Atacama is shipped to the company's port in Tocopilla in either crystallized (standard) or granular (compacted) form and then shipped and sold as a commodity fertilizer to third parties. All of the company's potassium chloride-related plants in the Salar de Atacama have a nominal production capacity of up to 2.6 million metric tons per year. Actual production capacity depends on the volume, quality, and performance of the salts used in the process, as well as the quality of the brine resources pumped from the Salar de Atacama.
Mount Holland Spodumene Deposits
The Mount Holland project is an integrated lithium project in Western Australia consisting of (i) an open-pit mine on the Earl Grey hard rock lithium deposit and a spodumene concentrator comprises Dense Media Separation (DMS) and flotation circuits, 120 kilometers southeast of Southern Cross, and (ii) a lithium hydroxide (LiOH) refinery, located in the town of Kwinana, 26.5 kilometers from the Port of Fremantle, from which the battery-grade LiOH product will be shipped. The concentrator at the Mt. Holland site has a nominal production capacity of 383,000 dry metric tons per annum concentrate at a grade of 5.5 per cent lithium oxide matching the refinery feed requirements. The refinery in Kwinana has the capacity to produce 50,000 metric tons per annum of lithium hydroxide.
The project is an unincorporated joint venture in which SQM and Wesfarmers, through a wholly owned subsidiary, each holding 50% of the assets. The joint venture is managed by Covalent, an entity equally owned (50/50) by SQM and Wesfarmers.
The Mount Holland project focuses on the extraction and beneficiation of spodumene reserves in the Earl Grey pegmatite group. The deposit consists of a main body of thick tabular pegmatites, which become progressively narrower and branch to the south and east of the main pegmatite until the main body splits into several narrower dikes. Sporadically, isolated box rock enclaves are found within the pegmatite body.
The first ore from the pit was mined in 2022 and the concentrator started commissioning in the third quarter of 2023. First concentrate production from both circuits was achieved in the last quarter of 2023 and the first export of spodumene concentrate was in the first half of 2024. In December 2023, construction of the concentrator plant was completed and in December 2024, the refinery is under construction, with the objective of completion during 2025.
Products Derived from the Mount Holland Spodumene Deposits
Spodumene Concentrate
After traditional drill and blasting, load and haul operations of the spodumene ore obtained from the open pit is sent to Run of Mine (ROM) ore pad, from which a crushing circuit is fed. The crushing circuit reduces the granulometry of the material and generates a particle size suitable for processing at the smaller scale DMS circuit of the concentrator plant. This crushing circuit also has an intermediary crushed ore stockpile. The concentrator also has a larger integrated flotation circuit for the treatment of the finer portion of ore.
Until full commissioning of the lithium hydroxide refinery at Kwinana, the concentrate will be trucked there for commissioning and production and will continue to be trucked to a storage facility at Bunbury, approximately 500 kilometers west of the Mt. Holland mine. At Bunbury, the product is distributed to the SQM and Wesfarmers joint venture partners to follow their individual shipping and marketing plans.
Lithium Hydroxide
At the Kwinana refinery, the spodumene concentrate feed is calcined in a rotary kiln and afterwards treated with sulfuric acid. The sulfated calcine is transferred to the leaching and impurity removal area and leached with a process liquor. The slurry is then neutralized and filtered. The filtrate is pumped into the purification area where it is passed through a filter to remove fine entrained particles and later enters the solution causticization area where caustic soda (NaOH) is added to convert the lithium sulfate to lithium hydroxide (LiOH) plus sodium sulfate (Na2SO4). Lithium hydroxide is then crystallized, dried and finally packaged for shipment and subsequent commercialization. The production capacity of the lithium hydroxide plant is designed to take the whole concentrate production from Mt. Holland and transform it into 50,000 metric tons of lithium hydroxide per year upon completion of its construction.
Future production will depend on the actual volumes and quality of the spodumene concentrate shipped by the concentrator operation, the refinery plant performance and prevailing market conditions.
Raw Materials
The company’s electricity needs are primarily covered by Power Purchase Agreements that the company entered into with Empresa Electrica Cochrane SpA (an AES affiliate) on December 31, 2012.
For the company’s supply of liquefied natural gas, the company maintains a five-year contract with Engie, which was executed in 2019 and some annual contracts to supply possible increases in demand. In addition, the company has a supply of liquefied petroleum gas (LPG) from Lipigas at the company’s Lithium Chemical production facility and the Salar de Atacama.

Material Individual Properties
El Norte Grande Caliche, Chile
The company’s mining operations are concentrated in the First Region of Chile, where the company mainly works in the mining areas of Tente en el Aire, Nueva Victoria Oeste, Hermosa and Torcaza, and in the Second Region of Chile, where the company works 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.
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 Victoria and Iris and the evaporation ponds at the Sur Viejo sector of the site. The areas 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. Solar energy and 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.
SQM directly or indirectly through subsidiaries owns, leases or holds concessions over the facilities where it carries out its operations.
Salar de Atacama, Chile
The operations of SQM in the Salar de Atacama are located in the Antofagasta Region of Chile, which covers the El Loa Province and the San Pedro de Atacama commune. The Salar de Atacama Project is in operation for the treatment of brines to obtain lithium and potassium salts, and as such it is in a production stage. The Salar de Atacama deposits are owned by Corfo, which grants special operating contracts or administrative leases to private companies for the extraction of brine. SQM and Albemarle have a lease agreement with Corfo to extract and produce lithium from brines stored in the Salar de Atacama deposit. Consequently, SQM must follow the terms of the agreement and also the conditions established in RCAs in order to retain operations in the Salar de Atacama. Exploration is routinely carried out within the established areas.
SQM leases an area of about 1,400 square kilometers with permission to extract brines from an area of 820 square kilometers with two core operations. It produces lithium at its southwest operation. The lease was signed in 1993 and expires on December 31, 2030.
Mount Holland Lithium Project, Australia
The Mount Holland project is a production stage integrated lithium project in Western Australia consisting of (i) an open pit mine and lithium concentrator operation, at Mount Holland, 100 kilometers southeast of Southern Cross, and (ii) a lithium hydroxide (LiOH) refinery located in the Town of Kwinana, 26.5 kilometers from the port of Fremantle, from where the LiOH will be shipped.
The project is an unincorporated joint venture in which SQM and Wesfarmers through a wholly owned subsidiary each holding 50% of the assets. The joint ventures are managed by Covalent, an entity equally owned (50/50) by SQM and Wesfarmers.
The project is accessed by land using the Parker Range Road and Marvel Loch-Forrestania road, which are an all-season gravel road. The Parker Range road is connected to the Great Eastern Highway, which is a paved road with connectivity to Southern Cross, Kalgoorlie and Perth. Also, the project has its own access by air using an airstrip and infrastructure in the southern part of the mine.
The Project comprises:
An open pit mining operation aimed at extracting lithium ore from the Earl Grey lithium deposit at Mount Holland, approximately 100 kilometers south of Southern Cross in Western Australia and 500 kilometers east of Perth.
A spodumene concentrator facility located at the Mount Holland site with a nominal production capacity of 383,000 metric tons per annum of dry spodumene concentrate at a grade of 5.5% Li2O.
A refinery in development, located in the Kwinana industrial precinct approximately 45 kilometers south of Perth, with the capacity to produce 50,000 metric tons per annum of battery-grade lithium hydroxide product (LiOH) for export globally.
The non-process infrastructure (NPI) required to support the Mount Holland and Kwinana sites, including roads, buildings, accommodation and the provision of logistics and utilities.
Transportation and Storage Facilities
Product transportation is carried out by trucks that are operated by dedicated third parties through long-term contracts. SQM leases port and storage facilities for the transportation and management of finished products and consumable materials.
SQM's main centers for the production and storage of raw materials are the facilities in Nueva Victoria, Coya Sur and Salar de Atacama in Chile and Mount Holland in Australia. Other facilities include chemical plants for the finished products of lithium carbonate and lithium hydroxide at its Lithium Chemical Plant near the city of Antofagasta, Chile, the lithium hydroxide refinery in Western Australia (part of the Mount Holland project), and the Port of Tocopilla terminal in Chile, which is the principal facility for the storage and shipment of its bulk products and packaged potassium chloride (MOP), nitrates and lithium carbonate.
In Chile, the nitrate finished products are produced at the company’s Coya Sur facilities and then transported via trucks to the Port of Tocopilla terminal where they are stored and shipped in bulk or packaged in polypropylene bags, polyethylene or polypropylene bags. The latter can also be transported and stored in an alternative port (Mejillones) for later shipment.
The potassium chloride is produced at the company’s Salar de Atacama facilities and the company transports it by truck, either to the Port of Tocopilla terminal, the Coya Sur facility or the alternative Port of Mejillones for its shipment. The product transported to Coya Sur is an intermediate product that is used as a raw material for the production of potassium nitrate. The product transported to the Port of Tocopilla or Mejillones is a final product that will be shipped or transported to the customer or affiliate. The nitrate raw material for the production of potassium nitrate in Coya Sur is produced at Nueva Victoria.
Lithium chloride solution, which contains a high concentration of boron, is produced at the company’s Salar de Atacama facilities, and is transported to the lithium carbonate plant at its Lithium Chemical Plant area where the finished lithium carbonate is produced. Part of the lithium carbonate is provided to the adjacent lithium hydroxide plant where the finished lithium hydroxide is produced. These two products are packed in packaging of distinct characteristics such as polyethylene bags, multi-layer or polypropylene FIBC big bags, and stored within the same facilities in secured storerooms. The products are later consolidated into containers that are transported by trucks to a transit warehouse or directly to port terminals for their subsequent shipment. The port terminals used are suited to receive container ships and are situated in Antofagasta, Mejillones and Iquique. Lithium carbonate can also be transported in packaged format both to the Port of Tocopilla and to an alternative port (Mejillones) to be shipped in break bulk format.
Iodine obtained from the same caliche used for the production of nitrates, is processed, packaged and stored exclusively in the Pedro de Valdivia and Nueva Victoria facilities. The packaging used for iodine are drums and polypropylene FIBC big bags with an internal polyethylene bag and oxygen barrier, which are consolidated into containers and sent by truck to port terminals suited for their management, principally located in Antofagasta, Mejillones and Iquique. Thereafter, they are sent to distinct markets by container ship or by truck to Santiago where iodine derivatives are produced in the Ajay-SQM Chile plants. Drums and maxibags can also be transported on flat ramps to an alternative port (Mejillones) to be shipped in break bulk format.
In Australia, spodumene concentrate production from the Mount Holland mine began in 2023. Until the full ramp-up of the lithium hydroxide refinery in Kwinana, the concentrate will be trucked to a storage facility in Bunbury, approximately 500 kilometers west of the Mount Holland mine. At Bunbury, the product is distributed to both JV partners SQM and Wesfarmers, for them to follow their individual shipment and commercialization plans. For the ground logistics from Mount Holland mine to Bunbury Port, bulk haulage operators are responsible to haul the spodumene concentrate via haul trucks on public road. The haulage operator has a certification awarded by Bureau Veritas for the provision of bulk haulage and warehouse services, transport of controlled waste dangerous goods, operation and maintenance of heavy vehicles in accordance with the requirements of the management system standards, ISO 9001:2015 and ISO 45001:2018.
In Chile, the company owns and operates the port and storage facilities at the Port of Tocopilla terminal for the transportation and management of finished products and consumable materials. The Port of Tocopilla terminal facilities cover approximately 22 hectares and are located approximately 186 kilometers north of Antofagasta, approximately 124 kilometers west of María Elena and Coya Sur and 372 kilometers to the west of Salar de Atacama. The company’s affiliate, Servicios Integrales de Tránsitos y Transferencias S.A. (SIT), operates facilities for the shipment of products and the delivery of certain raw materials based on renewable concessions granted by Chilean regulatory authorities, provided that the facilities are used in accordance with the authorization granted and the company pays an annual concession fee. The facilities include a truck weighing machine that confirms product entry into the port and transfers the product to distinct storage zones, a piezometer within the shipping system to carry out bulk product loaded onto ships, a crane with a 40-ton capacity for the loading of sealed product onto ships and a nitrate mixing facility.
The storage facilities consist of a system of six silos, with a total storage capacity of 55,000 metric tons, and a mixed storage area of open and covered storehouses with a total storage capacity of approximately 250,000 metric tons. In addition, to fulfill future storage needs, the company will continue to make investments in accordance with the investment plan outlined by management. The products are also put into bags at the Port of Tocopilla terminal facilities where the bagging capacity is established by two bag packaging machines, one for sacks and polypropylene FIBC big bags and one for FFS polyethylene. The products that are packaged in Tocopilla may be subsequently shipped at the same port or may also be consolidated into trucks or containers for its subsequent dispatch to clients by land or sea through containers from other ports, principally located in Antofagasta, Mejillones and Iquique.
For the transportation of bulk product, the transportation belt system extends across the coastline to deliver products directly to the hatches of bulk cargo ships. The nominal load capacity of this shipping system is 1,200 tons per hour. The transportation of packaged product is carried out utilizing the same bulk cargo ships using barges without motors located in the dock and loaded by a crane with a 40-ton capacity from the Port of Tocopilla terminal. Thereafter, they are towed and unloaded using ship cranes to the respective warehouses.
The company normally contracts bulk cargo ships to transfer the product from the Port of Tocopilla terminal to the company’s hubs around the world or to clients directly, who, in certain instances, use their own contracted vessels for delivery.
Tocopilla processes related to the reception, handling, storage and shipment of bulk/packaged nitrates produced at Coya Sur are certified by the third-party organization TÜV-Rheinland under the quality standard ISO 9001:2015. The Port of Tocopilla has also Responsible Care, ISO 14000 and Ecoport certifications.
