Our strength and scale reflect the courage shown by past generations, and the curiosity of our current employees, who continue to shape important partnerships with companies, communities, and countries - constantly evolving our business and our products to support the world around us. We have marked a wide range of milestones through our 150 years of operation; these are a few of the moments that shaped the Rio Tinto of today. 150 years of Rio Tinto 4 1873 Rio Tinto commences copper mining in Spain The Rio Tinto Company was registered in London after a British-European investor group bought the Rio Tinto mines in Spain, first mined in Phoenician and Roman times. We introduced new processing facilities and techniques that transformed the operation, and by the turn of the century, we were producing 10% of the world's copper. 2007 Becoming a global leader in aluminium We acquired Alcan, becoming a global leader in aluminium, and further diversifying our portfolio. Through this deal, we also obtained access to water rights and renewable power through a vast network of hydropower facilities in Canada, a major competitive advantage to our smelting business. While Alcan was clearly a leader in green aluminium, the acquisition resulted in an unsustainable level of debt when the global financial crisis happened and left the company in a vulnerable financial situation. Annual Report 2022 | riotinto.com 1929-1953 Exploring new lands We looked beyond Spain's borders for growth opportunities, setting up a series of joint ventures to explore and develop mines, starting in 1929 with the great copper belt of what is now known as Zambia. Come 1952, our exploration team expanded into South Africa and Canada, and the following year Australia, resulting in new uranium mines in Canada and Australia. 1955-1963 The red cliffs of Australia In 1955, a geologist discovered bauxite in Queensland and commercial bauxite mining began at Weipa in 1963, where we still mine today. 2000-2022 Shaping our portfolio At the turn of the new century, we embarked on an acquisition and divestment programme, which simplified the business, focused the Group on large, low-cost mines and culminated in our divestment of our coal assets in 2018. We became the first major miner to cease coal production. We acquired North Ltd in 2000, significantly expanding our iron ore assets, including mines, rail and port capacity. And in 2006, we partnered with Ivanhoe Mines to construct and operate Oyu Tolgoi in Mongolia. In 2022, we acquired full ownership of Turquoise Hill Resources Ltd, increasing our direct ownership in Oyu Tolgoi to 66%. 2008-2019 Technology redefines the business In an attempt to transform the efficiency and safety of the way we mine, we partnered with Komatsu to be among the first in the world to trial the world's first driverless haul trucks. This initiative set us on a path to become a global leader in fully integrated, automated mining. In 2019, together with our partner Hitachi, we launched the world's first fully autonomous, long-distance, heavy-haul rail network - AutoHaul™.#7#8#9#10#11#12#13#14#15#16#17#18#19#20#21#22#23#24#25#26#27#28#29#30#31#32#33
