 In addition, we have a supply of liquefied petroleum gas (LPG) from Lipigas at our Lithium Chemical Plant and the Salar de Atacama.
We obtain ammonium nitrate, sulfuric acid, hydrochloric acid, kerosene, sulphur, calcium oxide and soda ash from several large suppliers, mainly in Chile, the United States and Europe, under long-term contracts or general agreements, some of which contain provisions for annual revisions of prices, quantities and deliveries. Diesel fuel is obtained under contracts that provide fuel at international market prices.
At Mt. Holland, different reagents are added at various points in the concentrator. Ferrosilicon is added to facilitate the gravity separation in the DMS circuit, and collector, flocculants and coagulant reagents are utilized in the flotation circuit, among others. The reagents are stored at a weatherproof storage shed on site. In the refinery, sulfuric acid and caustic soda will be delivered via pipeline, and all other reagents by truck to a designated off-loading facility for storage within the refinery. 
For main power supply at Mt. Holland, the substations on site were connected in January 2023 to Western Power’s 132kV grid power network (Bounty station). At the Kwinana refinery, the power is supplied from Western Power’s grid connection via the 132/22kV Kwinana Beach Power (KBP) switchyard which was commissioned in October 2023. 
To support the heating in the pyrometallurgical system of the refinery, a gas pipeline between the existing ATCO natural gas network and the Kwinana refinery site boundary was connected and installed. Gas will be supplied by a local supplier. A diesel refueling facility is to be installed on site in 2024 with diesel fuel being trucked to site.
We believe that all of our contracts and agreements with third-party suppliers with respect to our main raw materials contain standard and customary commercial terms and conditions.

Water Supply
We hold water rights for the supply of surface and subterranean water near our production facilities. The main sources of water for our nitrate and iodine facilities at Pedro de Valdivia, María Elena and Coya Sur are the Loa and San Salvador rivers, which run near our production facilities. Water for our Nueva Victoria and Salar de Atacama facilities is obtained from wells near the production facilities. For our lithium carbonate and lithium hydroxide production processes at
