Sinead became Chief Executive, Minerals in March 2021
Since joining Rio Tinto in 1997 as a geologist, Sinead has held senior leadership and operational roles across Aluminium, Copper & Diamonds, Energy & Minerals, and Iron Ore. Most recently, she was Managing Director, Operations, at Copper & Diamonds.
Sinead brings to her current role strong operational expertise and asset leadership combined with a track record and commitment to sustainability: under her tenure as Managing Director, Copper & Diamonds, our Kennecott copper operation in Utah, US, became the first in the world to be awarded the Copper Mark, the industry’s independently assessed responsible production programme. Sinead also oversaw the reduction of Kennecott’s carbon footprint by more than 60%, achieved by closing the coal-fired power station and using renewable energy carbon offsets.
