Sherritt International

Sherritt International is a Canadian resource company, based in Toronto, Ontario. Sherritt is a miner and refiner of nickel and cobalt. Sherritt is also the largest independent energy producer in Cuba. Sherritt’s common shares are listed on the Toronto Stock Exchange under the symbol "S". Operations Mining Moa Joint Venture Sherritt has a 50/50 partnership with General Nickel Company S.A. (GNC) of Cuba (the Moa Joint Venture) and a wholly‑owned fertilizer business and sulphuric acid, utilities and fertilizer storage facilities in Fort Saskatchewan, Alberta, Canada (Fort Site) that provides additional sources of income. The Moa Joint Venture mines, processes and refines nickel and cobalt for sale worldwide (except in the United States). The Moa Joint Venture is a vertically‑integrated joint venture that mines lateritic ore by open pit methods and processes them at its facilities at Moa, Cuba into mixed sulphides containing nickel and cobalt. The mixed sulphides are transported to the refining facilities in Fort Saskatchewan, Alberta. The resulting nickel and cobalt products are sold to various markets, primarily in Europe, Japan and China. At current depletion rates, the concessions of the Moa Joint Venture are planned to be mined until at least 2034. In Q2 2019, the Moa Joint Venture filed an updated National Instrument 43-101 technical report on SEDAR that confirmed the current mineral reserves and outlined increased mineral resources with the potential to extend Moa's mine life. The Fort Site facilities provides inputs (ammonia, sulphuric acid and utilities) for the Moa Joint Venture metals refinery, produces agriculture fertilizer for sale in Western Canada and provides additional fertilizer storage and administrative facilities. The metals refinery facilities in Fort Saskatchewan have an annual production capacity of approximately 35,000 (100% basis) tonnes of nickel and approximately 3,800 (100% basis) tonnes of cobalt. Ambatovy Joint Venture In 2007, Sherritt acquired a 40% interest in the Ambatovy Joint Venture to develop and build a vertically-integrated nickel and cobalt mining, processing, refining and marketing operation in Madagascar. The Joint Venture reached commercial production in 2014 and comprises (i) a mine and an ore preparation plant located in the immediate vicinity of the ore bodies near Moramanga in eastern central Madagascar, (ii) a pipeline, approximately 220 kilometres long, to transport the mined laterite ore in the form of prepared slurry from the ore preparation plant at the mine to the processing plant which is located just south of the port city of Toamasina, and (iii) a processing plant, including a refinery, that produces LME-grade finished nickel, as well as cobalt metal. In 2017, Sherritt exchanged CAD1.4 billion in debt to its joint venture partners for 28% of its interest in the joint venture. In 2020, Sherritt exchanged its 12% interest in the joint venture for the remaining partner loans. Oil and gas Sherritt's Oil and Gas division explores for oil and gas primarily from reservoirs located offshore, but close to the coastline along the north coast of Cuba. Specialized long reach directional drilling methods are being used to economically exploit these reserves from land‑based drilling locations. Sherritt currently has an interest in three PSCs in the exploration phase. In addition, Sherritt holds working‑interests in several oil fields and the related production platform located in the Gulf of Valencia in Spain. Electricity Sherritt's primary power generating assets are located in Cuba at Varadero, Boca de Jaruco, and Puerto Escondido. These assets are held by Sherritt through its one‑third interest in Energas S.A. (Energas), which is a Cuban joint arrangement established to process raw natural gas and generate electricity for sale to the Cuban national electrical grid. Cuban government agencies Unión Eléctrica (UNE) and Unión Cubapetróleo (CUPET) hold the remaining two‑thirds interest in Energas. Raw natural gas is supplied to Energas by CUPET free of charge. The processing of raw natural gas produces clean natural gas, used to generate electricity, as well as by‑products such as condensate and liquefied petroleum gas. All of Energas' electrical generation is purchased by UNE under long‑term fixed‑price contracts while the by‑products are purchased by CUPET or a Cuban entity providing natural gas to the city of Havana at market based prices. Sherritt provided the financing for the construction of the Energas facilities and is being repaid from the cash flows generated by the facilities. The Energas facilities, which consist of the two combined cycle plants at Varadero and Boca de Jaruco, produce electricity using natural gas and steam generated from the waste heat captured from the gas turbines. Energas' electrical generating capacity is 506 MW. Fertilizer Sherritt owns assets, which produce fertilizer products, primarily for sale in the Western Canadian market, and which provide some of the critical input requirements for the Fort Saskatchewan metals refinery. Revenue is derived primarily from the sale of nitrogen fertilizers, and of sulphate fertilizers produced directly or indirectly as a by-product of the metals refining process. Technologies Sherritt's Technologies group provided technical support, process optimization and technology development services to Sherritt's operating divisions, and identified opportunities for the Corporation as a result of its research and development activities. Its activities included the internally focused development of technologies that provided strategic advantages to the Corporation; evaluating, developing and commercializing process technologies for natural resource based industries, in particular for the hydrometallurgical recovery of non-ferrous metals; and providing technical support for Sherritt’s operations, marketing and business development arms. The Technologies division was closed in July 2025 as part of the organization's efforts to adapt to the current business environment (low nickel prices), resulting in a significant reduction of Sherritt's workforce. History The company was named after Carl Sherritt, an American citizen and teamster on local rail construction projects who, after becoming a trapper and prospector, staked copper prospects in the Cold Lake area of Manitoba; and J. Peter Gordon, a civil engineer who had also worked on the railroad construction. Eldon Brown was the company's first employee and general superintendent. The company operated the Sherritt-Gordon Mine from 1931 until 1951, leaving behind 7.7 mega tons of tailings, polluting Kississing Lake in what the Winnipeg Free Press described the pollution around the mine as "one of the worst cases of acidic mine drainage in the world".
